Description

Feeding device and grinding machine comprising same

Technical Field

The utility model relates to a material loading adjustment technical field in equipment such as grinding machine specifically provides a loading attachment and including this loading attachment's grinding machine.

Background

A grinding machine is a device for grinding a piece of hard and brittle material. Such as grinding machines, typically include a loading assembly, a feeding assembly, and a grinding assembly. Taking a part made of a hard and brittle material as a silicon rod as an example, for example, firstly fixing the cut silicon rod to a feeding assembly, performing certain initial adjustment on the position and posture of the feeding assembly, and then conveying the silicon rod to a position between two chucks of the feeding assembly, wherein for example, the two chucks can be both movable chucks or one chuck is a movable chuck and one chuck is a fixed chuck. And the silicon rod is conveyed to the grinding assembly through the axial movement of the silicon rod, so that the first group of surfaces to be ground are subjected to grinding processing including rough grinding and fine grinding. Thereafter, the silicon rod is rotated to a second group of surfaces to be ground by rotating the silicon rod, and the second group of surfaces to be ground is subjected to grinding including rough grinding and finish grinding. And repeating the steps until all surfaces to be ground of the silicon rod are ground according to the set grinding standard.

Still taking the hard and brittle material as the silicon rod as an example, because the specifications of the silicon rods are different and the external dimensions of the silicon rods with the same specification are also different, when the silicon rods are placed on the feeding platform, a certain position deviation usually exists between the axis of the silicon rod and the axes of the two chucks. In addition, due to the fact that the surface of the silicon rod before grinding is not flat, a certain angle deviation exists between the axis of the silicon rod and the axes of the two chucks. Obviously, the existence of the position deviation and the angle deviation can affect the coaxiality of the two axes, and the coaxiality between the two axes is shown as the feeding precision of the silicon rod on the grinding machine. The unqualified position deviation and angle deviation can affect the feeding precision of the silicon rod, and the reduction of the feeding precision can be generally expressed as the increase of the grinding quantity of the silicon rod and the improvement of silicon loss in different degrees, so that the processing efficiency of a grinding machine is reduced, and the surface quality of the silicon rod is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving above-mentioned technical problem at least partly, particularly, restrain or eliminate arbitrary link in above-mentioned position deviation and the angular deviation to improve the material loading precision of silicon rod on this basis, reduce silicon rod grinding volume, reduce the silicon loss on this basis.

In a first aspect, the utility model provides a loading device, this loading device includes: 1) Material loading subassembly, it includes: 11 A lifting assembly including a pallet on which a workpiece to be processed can be set, the lifting assembly being capable of lifting the workpiece to be processed set on the pallet in a vertical direction and allowing different portions of the workpiece to be processed to be lifted at different heights; 12 Clamping assembly comprising a clamping first end assembly, a clamping second end assembly and an adjustment assembly arranged on said clamping first end assembly and/or said clamping second end assembly, said adjustment assembly being capable of varying the distance between different parts of the piece to be machined and the respective clamping first end assembly and/or said clamping second end assembly.

With such a configuration, the loading height of the workpiece to be machined, for example, a silicon rod to be ground, can be increased in three dimensions by the loading device.

Compared with the mode of carrying out manual participation after the workpiece to be processed is directly blanked (bar withdrawing), the workpiece to be processed is directly placed in the feeding device for readjustment, so that the adjustment efficiency is improved. Compared with the mode of adjusting the feeding direction through the fixed clamping head and the movable clamping head, the feeding device has the advantages that the number of parts involved in the structure of the feeding device is relatively large, and therefore feeding precision adjustment in four dimensions can be achieved through different parts. In addition, the feeding device is separated from the movable clamping head and the fixed clamping head in structure, so that adjustment of corresponding dimensions can be realized more easily by means of adding parts and the like.

Particularly, through the setting of lifting subassembly, the utility model discloses make to set up when realizing the ascending of direction of height in the layer board, can also realize treating the fine setting of the different parts of machined part on the lifting height. Through the setting of centre gripping subassembly, will treat that the machined part is tight when pressing from both sides, can also realize treating the fine setting of the different parts of machined part on clamping position. Therefore the utility model relates to an adjustment includes following three dimension: height (hereinafter, positional adjustment along the Z-axis), height deviation (hereinafter, angular adjustment along the X-axis), and horizontal rotation (hereinafter, directional adjustment along the Z-axis).

It can be understood that, according to actual requirements, a person skilled in the art can determine the structural form of the lifting assembly and the implementation manner of the structural form to implement the two-dimensional adjustment of the to-be-processed member disposed on the supporting plate. By way of example, it is assumed that the lifting assembly comprises a mechanism 1 and a mechanism 2, wherein the mechanism 1 can achieve height adjustment and the mechanism 2 can achieve height deviation adjustment. Such as may be: the

units

1 and 2 can be operated independently of one another, so that the height adjustment and the height deviation adjustment can be carried out without interference in space-time (e.g., simultaneously or in any desired sequence); the mechanism 1 and the mechanism 2 have a cooperative relationship in movement such that the height adjustment and the height deviation adjustment are achieved simultaneously or in a specific order (e.g., height adjustment is followed by height deviation adjustment); and so on.

Obviously, the mechanism 1 and the mechanism 2 may be in any form, as long as it is ensured that the workpiece to be processed can be lifted and deviations in the lifting height can occur. For example, the

mechanisms

1 and 2 may be independent mechanisms or have associated mechanisms (e.g., some structural coincidence therebetween, one being part of the other, the two being connected by an intermediate member, etc.).

It can be understood that, a person skilled in the art may determine the structural form of the adjustment assembly and the configuration thereof in the clamping first end assembly and/or the clamping second end assembly and the specific configuration position according to actual requirements, wherein the clamping second end assembly and the clamping first end assembly may be both movable ends or one fixed end and one movable end. Illustratively, an adjustment assembly is disposed on each of the clamped first end assembly and the clamped second end assembly. The adjusting component can be a structure additionally arranged on the first end clamping component and the second end clamping component, or a structure formed by mutually combining with a part of the existing structures for clamping the first end clamping component and the second end clamping component. The adjustment assembly is illustratively a separate structure that angularly adjusts the workpiece along the Z-axis in a manner that causes different portions of the workpiece to be angularly displaced from the respective clamping first end assembly and/or clamping second end assembly. If the adjusting assembly comprises a mechanism 3 and a mechanism 4, the mechanism 3 and the mechanism 4 are respectively arranged outside the first end clamping assembly and the second end clamping assembly, and the distances between different parts of the workpiece to be processed and the corresponding first end clamping assembly and/or second end clamping assembly are different in a mode of 'the mechanism 3 can push one end of the first end clamping assembly to displace in a first direction (along the length direction of the workpiece to be processed) and the mechanism 4 can push the other end of the second end clamping assembly to displace in the opposite direction of the first direction', so that the angle adjustment of the workpiece to be processed along the Z axis is realized.

As for the above feeding device, in a possible implementation, the feeding device further comprises: 2) The feeding platform assembly comprises a feeding platform, a discharging platform and a driving transmission mechanism, wherein the driving transmission mechanism drives the feeding assembly carrying the workpieces to be processed to move along the direction between the feeding platform and the discharging platform, and therefore the workpieces to be processed are adjusted to move along the direction of movement.

With such a configuration, it is possible to increase the feed height of the workpiece to be processed from the fourth dimension on the basis of the three dimensions.

Particularly, through drive transmission's setting, the utility model discloses a drive transmission can also realize its material loading precision adjustment along last unloading direction (the position adjustment along the X axle of following said) when realizing the basic function of unloading from it.

It can be understood that, in order to ensure that the precision adjustment can reach the standard, a person skilled in the art can directly utilize the driving transmission mechanism corresponding to the basic transfer function according to actual requirements, add a certain structure and/or add a certain control logic on the basis of the driving transmission mechanism, and the like.

For the loading device, in one possible embodiment, the lifting assembly comprises: a first drive member; a lifting wheel set comprising a plurality of lifting wheels, the first drive member in driving connection with the lifting wheels, the lifting wheels in operative connection with the pallet; the first driving part can drive the lifting wheel to rotate so as to lift the supporting plate and a to-be-processed workpiece arranged on the supporting plate; the lift assembly further comprises: an adjustment portion in signal connection with at least the lift wheel to: the lifting heights of the supporting plate corresponding to the positions of the plurality of lifting wheels are different.

By this construction, a specific form of construction of the lift assembly is given.

It should be noted that the drive connection in "the first drive member is in drive connection with the elevator wheel" is to be understood as: when the first driving component sends out a driving action, the lifting wheel can concomitantly generate an action related to the driving action, namely the lifting wheel can generate actions such as lifting and the like in response to the driving of the first driving component. For example, the first driving part and the lifting wheel can be in direct driving connection or indirect driving connection.

It should be noted that the operative connection in the "operative connection of the lifting wheel to the pallet" is understood to mean: when one of the lifting wheels and the supporting plate acts, the other one concomitantly acts in association with the action, namely, the two have an association at the operation level, for example, the two can be in direct association or indirect association.

It should be noted that the signal connection in "the adjustment portion, which is at least in signal connection with the lifting wheel" should be understood as: according to different control instructions of the adjusting part, the lifting wheel can generate a lifting height corresponding to the instructions. It is obvious that a person skilled in the art can make a mapping relationship between the control command and the lifting height according to actual requirements. Alternatively, based on such signal connection, the mapping relationship between the control command and the lifting height can be flexibly selected according to actual requirements, the map can be known, conventionally selected or flexibly made according to actual situations, and the like.

It is understood that the structural form, the number, the relative position between each lifting wheel (in the case that the lifting wheels include a plurality of lifting wheels) and the relative position between the lifting wheels and the supporting plate can be determined by those skilled in the art according to actual needs. Such as may be: the lifting wheels comprise two groups, and the two groups of lifting wheels are arranged at positions close to two ends of the silicon rod; the silicon rod lifting device comprises four lifting wheels, wherein the four lifting wheels are respectively marked as A, B, C and D, A and C are a group, the silicon rod arranged on a supporting plate can realize the lifting in the first form by means of the lifting wheels (A and C), B and D are a group, and the silicon rod arranged on the supporting plate can realize the lifting in the second form by means of the lifting wheels (B and D); and the like.

It can be understood that, a person skilled in the art can determine the specific form of the displacement of the lifting wheel set driven by the first driving component and the corresponding relationship between the driving component and the lifting wheel set according to actual needs. For example, the first driving component can directly drive or indirectly drive the lifting wheel set to displace. The form of indirect drive may be: the power output end of the first driving component is directly connected with one or more intermediate components, and when the state of the first driving component driving the intermediate components is changed, the lifting wheels can generate displacement along the height direction based on the state change. And the corresponding relationship between the first driving component and the lifting wheel group can be one-to-one correspondence, one first driving component corresponds to a plurality of lifting wheels, one lifting wheel corresponds to a plurality of first driving components, and the like. Illustratively, the lifting wheels include two, and the two first driving members respectively drive the two lifting wheels in a relatively independent manner.

It is understood that the direction of the displacement of the lifting wheel driven by the first driving member and the displacement amount can be determined by those skilled in the art according to actual needs. For example, the direction may be a displacement only including the height direction, or may be a displacement including, but not limited to, other directions such as the horizontal direction. For the displacement amount, a person skilled in the art can set how the driving component can cause the lifting wheel to generate the expected displacement amount according to a driving mode of the lifting wheel driven by the first driving component to generate the displacement, a displacement amount required by the workpiece to be processed, and the like.

It can be understood that a person skilled in the art can determine the specific structural form of the supporting plate according to actual requirements, such as directly arranging the supporting plate or adding a corresponding functional structure on the supporting plate and then arranging the workpiece to be processed on the functional structure.

With regard to the above-mentioned loading device, in a possible embodiment, a part of the plurality of lifting wheels is fixedly connected to the pallet in a rotatable manner, the lifting assembly further comprising a transmission member connected to the first driving member on the one hand and interfacing with the lifting wheels on the other hand, wherein the transmission member has an inclined guide surface in a position close to the lifting wheels such that: when the first driving component drives the transmission component to move transversely, the lifting wheel rotates along the guide surface and lifts the supporting plate and the workpiece to be machined arranged on the supporting plate; another part of the plurality of lifting wheels is configured with an eccentric shaft configured with a second driving means such that: the second driving component drives the eccentric shaft to rotate and/or the lifting wheel corresponding to the eccentric shaft to rotate around the eccentric shaft, so that the supporting plate and different parts of the workpiece to be machined, which are arranged on the supporting plate, are allowed to be lifted at different heights.

By means of the structure, a specific implementation mode of the lifting assembly for achieving feeding precision adjustment of two dimensions is provided.

It should be noted that the rotation in "a part of the plurality of lifting wheels is fixedly connected to the supporting plate in a rotatable manner" should be understood as the rotating property of the lifting wheels, and the fixed connection should be understood as the connection relationship between the lifting wheels and the supporting plate. Illustratively, the lifting wheel is provided with a shaft, the shaft is fixedly connected to the supporting plate, and the lifting wheel can rotate around the shaft. Illustratively, the pallet is generally a housing structure, the workpiece to be processed is fixed to the top of the housing structure, and the lift wheels are mounted on the sides of the housing structure via axles.

It is understood that the structural form, the number of the transmission components and the specific motion form generated by the first driving component can be determined by those skilled in the art according to actual requirements. For example, the transmission component may be a plate-shaped structure, a block-shaped structure, a strip-shaped structure, etc., and the movable form of the transmission component may include moving, rotating, a combination of the two, etc. For example, the lifting wheels may share one transmission member, each lifting wheel may be provided with a plurality of transmission members, and the lifting wheels may correspond to the transmission members one by one.

An inclined guide surface is here to be understood as: the height of the downstream side of the guide surface should be lower than the height of the upstream side of the guide surface, as seen in the traversing direction of the transmission member. The guide surface having such a characteristic may be a slant surface, a (concave, convex) curved surface, a combination thereof, or the like. The first driving part is taken as a power cylinder, the guide surface is taken as an inclined surface as an example, the transmission part moves transversely along with the extension of a power output shaft of the power cylinder, and due to the arrangement of the inclined surface, the lifting wheel generates vertical upward displacement along with rotation and rolling of the lifting wheel on the inclined surface, so that the supporting plate can be driven to generate displacement along the vertical direction, and the lifting of the workpiece to be processed is realized. For example, the first driving member may be a power cylinder or a motor. For example, the power cylinder can be an electric cylinder, an air cylinder, a hydraulic cylinder and the like. At this time, the transmission part can be directly connected with the piston as a power output shaft. In the case where the driving member is a motor, for example, the shaft of the motor should be indirectly connected to the transmission member through a transmission mechanism such as a lead screw nut pair to effect lateral movement of the transmission member. Since the second driving component is mainly used for driving the eccentric shaft to rotate, the second driving component is usually a motor.

Through the resultant motion formed by the rotation of the lifting wheels around the eccentric shaft and the rotation of the eccentric shaft, under the action of the transmission component, the lifting heights among the plurality of lifting wheels are different, so that the different lifting heights of the part to be machined are different.

It will be understood that a person skilled in the art can determine the specific specification of the eccentric shafts and the specific number and positions of the eccentric shafts configured in the lifting wheel according to actual requirements, and the like, and the lifting wheel exemplarily includes two lifting wheels, one of which is a common shaft and the other is an eccentric shaft.

With regard to the above feeding device, in a possible embodiment, the lifting assembly includes a constraining component, and the supporting plate generates displacement along the height direction under the cooperation of the constraining component, and thus lifts the supporting plate and the workpiece to be processed arranged on the supporting plate along the vertical direction.

With this configuration, the reliability of the lift assembly can be ensured.

In particular, the lifting path of the pallet is defined by the guiding and/or limiting action of the constraining means. It should be understood that the structural form, the number of the guide and limit stop members, the relationship between the guide and limit stop members and the supporting plate, etc. can be determined by those skilled in the art according to actual requirements. Such as may be: the guide limiting component comprises a baffle plate/a baffle rib arranged outside the supporting plate in a surrounding way, a guide rail matched with the supporting plate and the like.

In a possible embodiment, the constraint component is a connecting shaft, and the supporting plate is provided with a hole, and the connecting shaft is freely accommodated in the hole.

By such a constitution, a specific configuration of the restricting member is given.

With regard to the above feeding device, in a possible implementation manner, the supporting plate includes a first bottom plate, the lifting assembly includes a return spring, and the return spring is disposed between the first bottom plate of the lifting assembly and the supporting plate.

Particularly, through the setting of reset spring, guaranteed that the layer board can return reliably. For example, in the process that a power output shaft (piston) of the power cylinder extends out and a supporting plate is lifted, the return spring is in a stretched state. When the power output shaft of the power cylinder retracts, the supporting plate descends under the combined action of the pulling force of the reset spring and the self gravity of the supporting plate, and therefore the supporting plate is reset.

It is understood that the specification (such as elastic coefficient, etc.) of the return spring, the number of the arrangement, the arrangement position and the specific connection mode with the bottom plate and the supporting plate, etc. can be determined by those skilled in the art according to actual requirements. Illustratively, taking the constraining member as the shaft, the return spring, for example, comprises a plurality of springs distributed around the circumference of the shaft. In addition, a return spring can also be sleeved outside the connecting shaft.

For the loading device, in one possible embodiment, the adjustment assembly comprises: the second bottom plate is movably arranged on the second bottom plate, and the first end component and/or the second end component are/is clamped; a third drive member operatively connected to the respective clamping first end assembly or the clamping second end assembly to: the distance between the clamping first end assembly or the clamping second end assembly and different parts of the second base plate is different under the driving of the third driving part.

Through the structure, a specific implementation mode of realizing one-dimensional feeding precision adjustment of the adjusting assembly is provided. Particularly, fine adjustment of the angle of the silicon rod to be ground waiting for a workpiece can be realized along the feeding/clamping direction.

It should be noted that the operative connection of the "third driving member operatively connected to the respective clamping first end assembly and/or clamping second end assembly" is understood to mean: when the third driving member acts with one of the respective clamping first end assembly and clamping second end assembly, the other concomitantly acts in association with the action, i.e. both have an association in the operational level, e.g. the third driving member may be in direct drive connection or in indirect drive connection with the clamping first/second end assembly.

It will be appreciated that the second base plate may be directly or indirectly connected to the first/second end assembly, and that the difference in distance between the different parts may be achieved by rotation, movement or a combination thereof. Such as may be: the displacement of the second bottom plate and the clamping first/second end component at the first position is first displacement, and the displacement at the second position is second displacement different from the first displacement, so that different local distances between the second bottom plate and the clamping first/second end component are different; the second bottom plate and the first/second bottom plate can rotate on the one hand and move along the thickness direction (clamping direction) of the second bottom plate and the first/second bottom plate, and different local distances between the second bottom plate and the first/second bottom plate are different through two movement amounts; and the like.

It will be appreciated that one skilled in the art may configure the adjustment assembly for clamping the first/second end assembly according to actual needs. For example, if the mounting position for holding the first end assembly is assumed to be relatively fixed, configuring the adjustment assembly for holding the first end assembly may effectively prevent the adjustment amount of the adjustment assembly from interfering with other movements.

With regard to the above feeding device, in a possible implementation manner, the second bottom plate is reserved with an installation space, and the adjusting assembly includes: the first adjusting component is arranged on the clamping plate for clamping the first end assembly and/or the second end assembly, and freely accommodated in the mounting space and provided with a first adjusting structure extending out of the mounting space; a second adjustment member drivingly connected to the third drive member and having a second adjustment structure inclined at a side thereof adjacent the first adjustment member such that: when the third driving component drives the second adjusting component to move towards the direction close to the first adjusting component, the second adjusting structure presses against the first adjusting structure so as to drive the clamping plate and the second bottom plate to rotate relatively, and therefore the distances between different parts of the clamping plate and the second bottom plate are different.

By means of such a construction, a specific construction of the adjustment assembly is given.

In particular, the difference in distance from different parts of the clamping plate and the second base plate is achieved by cooperation with the first adjustment structure and the second adjustment structure.

It is understood that a person skilled in the art can flexibly select the structural form of the first/second adjusting component, the specific structural form of the first/second adjusting structure, the arrangement position, arrangement mode, etc. of the first/second adjusting structure on the first/second adjusting component according to actual requirements.

If the first/second adjusting structure can be fixedly connected or integrally formed on the first/second adjusting component, the cross section (along the thickness direction of the second base plate) of the first adjusting structure can be a cambered surface, an inclined surface, etc. Illustratively, the first adjusting component and the first adjusting structure are integrally formed and are approximately cylindrical blocks with cambered ends.

The inclination as in the "inclined second adjustment structure" should be understood as: the height of the downstream side of the second adjustment structure should be lower than the height of the upstream side, as viewed in a direction away from the first adjustment member toward the first adjustment member. The second adjustment structure having such a feature may be an inclined surface, a (concave, convex) curved surface, a combination thereof, or the like. Illustratively, the second adjustment member is integrally formed with the second adjustment structure and is generally a wedge-shaped block.

With regard to the above-described feeding device, in one possible embodiment, the first adjusting component is an adjusting top block and/or the second adjusting component is an adjusting wedge block.

With this configuration, a specific configuration of the first/second regulating member is given.

With regard to the above-mentioned feeding device, in one possible embodiment, the adjusting assembly comprises: the adjusting plate is arranged between the second bottom plate and the clamping plate, wherein the second bottom plate is movably connected with the adjusting plate, and the first adjusting part is fixedly connected with the adjusting plate or integrally formed.

By means of this construction, a specific design of the adjustment assembly is given.

In particular, since the clamping plate has stringent specifications both in terms of precision and functionality, and furthermore, as corresponds to the clamping plate assuming clamping of the first/second end assembly, is a movable component, it may also cooperate with other components. Consequently, through the setting of adjusting plate, can avoid the utility model discloses a realization of adjustment function influences original centre gripping subassembly's basic clamping performance.

In a possible embodiment, the adjusting plate is fixedly connected to the clamping plate or is integrally formed with the clamping plate.

It will be appreciated that the specific manner of attachment of the adjustment plate to the first adjustment member and the clamping plate may be determined by those skilled in the art based on actual requirements. Such as screwing, clamping, bonding, etc.

With regard to the above-mentioned feeding device, in one possible embodiment, the adjusting assembly comprises: a positioning member fixedly provided to the second base plate; and the adjusting plate is provided with a reserved space at a position corresponding to the positioning component; wherein a portion of the positioning member in the headspace has a gap with the headspace such that: the clamping plate and the second bottom plate are relatively rotated through the movement of the positioning component in the reserved space.

By means of this construction, a specific connection between the adjusting plate and the base plate is given.

In the case where the relative rotation occurs, the position corresponding to the positioning block corresponds to the pivoting side and the position corresponding to the first adjusting member corresponds to the free side for the adjusting plate. Therefore, in order to ensure that the rotation is achieved, the setting position of the accommodating space corresponding to the positioning block on the adjusting plate and the setting position of the installation space corresponding to the first adjusting part on the adjusting plate should have a certain distance.

With regard to the above-mentioned feeding device, in a possible embodiment, the positioning component is a positioning block.

By such a construction, a specific form of construction of the positioning member is given.

With regard to the feeding device, in a possible embodiment, viewed in the length direction of the workpiece to be processed, the position of the supporting plate near the middle of one side of the workpiece to be processed is a structure recessed in the direction away from the workpiece to be processed.

With this configuration, the workpiece can be more reliably set on the pallet.

With regard to the feeding device, in a possible implementation manner, the supporting plate comprises a supporting plate main body and a supporting plate, and the workpiece to be machined is arranged on the supporting plate, wherein the supporting plate is recessed towards a direction away from the workpiece to be machined at a position close to the middle part of one side close to the workpiece to be machined.

With this construction, a specific design of the pallet is given.

With regard to the feeding device, in a possible embodiment, viewed along the length direction of the workpiece to be processed, the support plates include two groups which are separately arranged, each group of the support plates includes at least one support plate, and a structure which is concave towards the direction away from the workpiece to be processed is formed between the two groups of the support plates; or the supporting plate is of an integrally formed structure, and a structure which is sunken towards the direction far away from the workpiece to be machined is formed at the position, close to the middle part, of the supporting plate.

By such a construction, a possible way of forming the recess in the pallet is given.

In a second aspect, the present invention provides a grinding machine comprising a loading device according to any one of the preceding claims.

It can be understood that the grinding machine has all the technical effects of the feeding device in any one of the foregoing embodiments, and the description is omitted here.

The present invention will be described below with reference to a part or all of fig. 1 to 18.

Referring mainly to fig. 1, in a possible embodiment, the main body of the grinding machine 1 mainly includes a base 101 and a vertical frame 102 disposed at the bottom, and the base 101 has a certain horizontal adjustment function, so as to provide a mounting surface with a high level for the structures of the loading device 11, the grinding device 13, and the like of the grinding machine 1. Wherein, the top of the vertical frame 102 is provided with a guide rail on which the feeding slide table device 12 is mounted. The grinding machine is mainly used for grinding the silicon rod 2 after being cut as a workpiece to be machined to a set specification. Specifically, the silicon rod 2 after being cut is ideally a rectangular parallelepiped having a width and a height equal to each other. In practice, however, the surface of the cut silicon rod 2 is not flat, as is usually the case: the middle part of the silicon rod is more convex than the two end parts, and the size of the silicon rod knife outlet is larger than that of the knife inlet (the side length of the square of the diamond wire cut-out end surface is larger than that of the square of the diamond wire cut-in end surface). Therefore, the cut silicon rod needs to be ground to an ideal rectangular parallelepiped with a standard specification by a grinding machine.

Referring mainly to fig. 2 and 3, in one possible embodiment, the loading device 11 is mainly used for clamping the silicon rod 2 by the fixed chuck 121 and the movable chuck 122 of the feed slide unit 12 after the silicon rod is adjusted to a suitable position and angle. In order to reduce the grinding amount, reduce the silicon loss and improve the grinding efficiency, the grinding machine 1 needs a high feeding precision. Under the condition that the feeding precision reaches the standard, the ideal axis of the silicon rod 2 and the axis between the movable chuck and the fixed chuck have higher coaxiality. The utility model discloses mainly make the axiality reach comparatively ideal level through loading attachment's adjustment.

In one possible embodiment, the feeding device 11 mainly comprises a feeding assembly 111, a centering assembly 112 and a feeding table assembly 113. Wherein the feeding assembly 111 and the feeding table assembly 113 require adjustment of the position and posture (hereinafter referred to as the attitude) of the silicon rod 2 in the aforementioned four dimensions, the centering assembly 112 is used to mainly determine the amount of adjustment of the attitude of the silicon rod 2 by the feeding assembly 111. Specifically, loading assembly 111 generally includes a lift assembly 1111 and a clamp assembly 1112. According to the detection result of the centering assembly 112, the lifting assembly 1111 is mainly used for performing position adjustment along the Z axis and angular adjustment along the X axis (rotation in a vertical plane) on the silicon rod 2, and the clamping assembly 1112 is mainly used for performing angular adjustment along the Z axis (rotation in a horizontal plane) on the silicon rod 2. The feeding table assembly 113 is mainly used for adjusting the position of the silicon rod along the X axis in the process of moving the feeding assembly 111 holding the silicon rod 2 to the centering assembly 112. Based on this, after the feeding assembly 111 completes the adjustment of the silicon rod in four dimensions, the silicon rod with the (fixed, movable) chuck clamping pose reaching the standard is made, and the feeding process is completed.

Referring mainly to fig. 4 to 7, in one possible embodiment, the lifting assembly 1111 mainly includes a first base plate 11111, an electric cylinder 11112 (first driving member), a driving plate 11113 as a driving member, a lifting wheel set including a first lifting wheel 111141 (e.g., the first lifting wheel includes two wheel units disposed on a first wheel shaft 111191) and a second lifting wheel 111142, and a support plate 11115, wherein the driving plate 11113 has slopes 111131 inclined downward from left to right as guide surfaces at positions corresponding to the first lifting wheel 111141 and the second lifting wheel 111142, respectively.

In this example, the power output shaft of the electric cylinder 11112 and the transmission plate 11113 are connected in the following manner: the first base plate 11111 is provided with a connecting block 11116 as a connecting component, the connecting block 11116 is fixedly connected with a transmission plate 11113 above the first base plate 11111 by means of a fastener such as a screw, and the like, the lower part of the connecting block 11116 is provided with a protruding end, correspondingly, the power output shaft of the electric cylinder 11112 is provided with an annular groove matched with the protruding end, and the connecting block 11116 is connected with the electric cylinder 11112 by the matching of the protruding end and the annular groove.

Thus, when the power output shaft of the electric cylinder 11112 extends rightward, the driving plate 11113 disposed at the bottom of the housing is driven to move rightward synchronously. In this case, the two lifting wheels mounted on the supporting plate 11115 can roll along the inclined plane 111131 from right to left, i.e. from low to high, and the supporting plate can be driven to move in the vertical direction along with the rolling. In this way, the position of the silicon rod set on the support plate 11115 along the Z axis is adjusted. Similarly, the power output shaft of the electric cylinder 11112 retracts, the transmission plate 11113 moves leftwards, the lifting wheel rolls from high to low, and the supporting plate 11115 descends. For example, in order to better guide the movement of the driving plate 11113, a sliding rail adapted to the movement track of the driving plate 11113 may be provided on the first bottom plate 11111.

As described above, one of the expressions that the surface of the silicon rod 2 after the cutting is not flat is: the middle portion of the silicon rod is convex compared to the two end portions. In order to enable a more smooth placement of the silicon rod with this property on the carrier, the middle of the carrier is recessed further away from the silicon rod than on both sides, i.e. downwardly in the figure.

Illustratively, the support plate 11115 includes a support plate body 111151, two sides of the support plate body extending along the length direction are respectively provided with an upwardly extending support plate 111152, the upper surface of the support plate 111152 is a reference surface (e.g. referred to as reference surface a) directly contacting with the lower surface of the silicon rod 2, such as an anti-slip layer or an anti-slip structure made of polyurethane or the like may be added on the upper side of the support plate, and the aforementioned recess is formed at a position of the support plate close to the middle part, as a specific implementation manner: each side is provided with two spaced apart support plates 111152 which may be secured to the top of the pallet by fasteners such as screws, forming a recess therebetween. In this example, the support plate has a structure to avoid the silicon rod at a mounting portion corresponding to the screw, such as a plurality of mounting locations provided on the support plate, the screw is provided at a position corresponding to the mounting location, and in a mounted state, the screw is completely accommodated at the mounting location and thus a top portion of the screw is not in contact with a bottom portion of the silicon rod.

It can be understood that, a person skilled in the art can flexibly adjust the manner of forming the recess in the pallet according to actual requirements, for example, two segments of separately arranged support plates can be integrally arranged, then the middle portion of the support plates can be integrally arranged to form the recess, and the support plates and the pallet main body can be integrally arranged.

In one possible embodiment, the first base plate 11111 is provided with a connecting shaft 1117 engaged with the support plate 11115, and a return spring 1118 is further provided between the first base plate and the support plate. By the arrangement of the connecting shaft 1117, the movement of the supporting plate 11115 in the X-axis and Y-axis directions is restricted, so that the supporting plate 11115 can move only in the Z-axis direction under the guidance of the connecting shaft. When the electric cylinder 11112 is extended and the support plate 11115 is raised, the return spring 1118 is in a compressed/extended (compressed in this example) state. When the electric cylinder 11112 retracts, the supporting plate 11115 descends under the action of the elastic force of the return spring 1118 and the self-gravity of the supporting plate 11115, so that the supporting plate 11115 is reset. As in this example, the pallet is provided with a hole in which the connecting shaft is freely accommodated so that the pallet can smoothly rise (rise)/fall (return) in the axial direction of the connecting shaft. The bottom end of the connecting shaft is fixedly connected with the first bottom plate or integrally formed, the top end of the connecting shaft is provided with a radial size larger than the hole, and the axial size of the connecting shaft can ensure the lifting amount required by the silicon rod.

As in this example, the pallet body of the pallet is substantially an enclosure structure with an open bottom, the aforementioned support plate is disposed on the top of the enclosure structure, and the elevating wheels are disposed on the sides of the enclosure structure. Illustratively, the two lift wheels are mounted to the pallet 11115 in the manner of: first and

second lift wheels

111141 and 111142 are mounted to the sides of the housing structure by first and

second axle shafts

111191 and 111192, respectively. When the electric cylinder 11112 extends/retracts, the pallet 11115 achieves the lifting/returning of the pallet 11115 along with the rotation of the two lifting wheels and the rolling of the two lifting wheels on the inclined plane 111131. Based on this, the function of the lifting assembly 1111 may be improved, and specifically, the lifting assembly may have a function of adjusting the position adjustment of the silicon rod along the Z-axis and a function of adjusting the angle adjustment of the silicon rod along the X-axis.

In one possible embodiment, one of the first and

second wheel axles

111191, 111192 may be modified to an eccentric axle (also denoted as 111191), such as by modifying the first wheel axle 111191 corresponding to the first lifting wheel 111141 to an eccentric axle in the present example, and configuring the first adjustment motor 1111911 for the eccentric axle, such as by connecting the first adjustment motor (second drive member) to the eccentric axle via a reducer-coupling. In this way, when the first adjustment motor drives the eccentric shaft corresponding to the first lifting wheel to rotate by a certain angle, the first lifting wheel 111141 mounted on the eccentric shaft is lifted/lowered by a certain distance, and at this time, the supporting plate 11115 rotates by a certain angle around the X axis due to a height difference between the two lifting wheels, thereby realizing the angle adjustment of the silicon rod along the X axis. In this case, the joint bearing 11171 is mounted on the connecting shaft 1117, so that the connecting shaft is provided to restrict the movement of the blade 11115 in the X-axis and Y-axis directions, but not to restrict the rotation of the blade 11115 about the X-axis. In an actual product, for example, a mounting position corresponding to the first adjustment motor may be provided at a position corresponding to each of the first lifting wheel 111141 and the second lifting wheel 111142, and in this example, a removable cover plate 1111921 may be provided at a position corresponding to the second lifting wheel 111142. By removing the closure plate, the first adjustment motor can be replaced to a position corresponding to the second lift roller 111142.

Therefore, the silicon rods on the supporting plate can be lifted by a certain height along the vertical direction through the matching of the electric cylinder, the transmission plate and the (first and second) lifting wheels. Through the cooperation of the first adjusting motor, the eccentric shaft and the first lifting wheel, different local positions of the silicon rod on the supporting plate along the height direction can be distinguished. In this way, a position adjustment along the Z axis and an angular adjustment along the X axis of the silicon rod can be achieved by the lifting assembly.

Referring mainly to fig. 8 to 12, in one possible embodiment, the clamping assembly 1112 mainly includes a clamping movable end assembly 11121 and a clamping fixed end assembly 11122, and the silicon rod 2 on the reference surface a of the support plate 11115 can be clamped in the X-axis direction by clamping the movable end assembly 11121 relative to the clamping fixed end assembly 11122. It should be noted that the clamping movable end assembly and the clamping fixed end assembly are only one specific form of the clamping assembly, and for example, both the clamping movable end assembly and the clamping fixed end assembly may be configured to be movable.

In one possible embodiment, the clamping movable end assembly 11121 mainly comprises a first air cylinder 111211, two sets of guide rail sliders (an X-axis guide rail slider 111212, a Y-axis guide rail slider 111213), a movable end return spring 111214 and a movable clamping plate 111215, wherein after the silicon rod 2 to be ground is placed on the reference surface a of the lifting assembly 1111, the first air cylinder 111211 is extended, and the slider of the X-axis guide rail slider 111212 slides on the guide rail by pushing the bottom plate of the clamping movable end assembly 11121, so as to push the movable clamping plate 111215 to move towards the clamping fixed end assembly 11122, thereby clamping the silicon rod in the X-axis direction. When the (fixed and movable) chuck clamps the silicon rod, the movable chuck 122 will push the silicon rod to move a little along the Y-axis, and accordingly, the movable clamping plate 111215 will also move a little along the Y-axis in a manner that the slide block of the Y-axis guide rail slide block slides on the guide rail, such movement will make the two movable-end return springs 111214 disposed along the Y-axis direction in a compressed state and a stretched state, respectively. After the silicon rod is clamped by the (fixed and movable) chuck, the first cylinder 111211 is retracted, and simultaneously the two movable end return springs 111214 are restored, so that the movable clamping plate 111215 is restored.

In one possible embodiment, clamp fixed end assembly 11122 consists essentially of a fixed clamp plate 111221 and an adjustment assembly. The fixed clamping plate is provided with a reference surface (such as a reference surface b), and the first cylinder 111211 drives the movable end clamping plate to move towards the direction close to the fixed end clamping plate, so that the silicon rod can be clamped along the X direction. Similar to the structure and function of clamping movable end assembly 11121, clamping fixed end assembly 11122 also provides a Y-axis rail slide and a fixed end return spring that enable the movable end clamping plate to return. The adjusting component is mainly used for realizing the angle adjustment of the silicon rod along the Z axis.

In one possible embodiment, the adjustment assembly mainly includes a second base plate 1112221, an adjustment plate 1112222 and a positioning block 1112223, wherein the positioning block 1112223 can be fixed on the second base plate 1112221 by a fastener such as a screw a11122231, the adjustment plate 1112222 is fixed on a fixed clamping plate at one side thereof, and the adjustment plate 1112222 is mounted on the second base plate 1112221 at the other side thereof (near the left side) by the positioning block 1112223. Wherein, there is a gap between the positioning block 1112223 and the adjustment plate 1112222, thereby allowing the adjustment plate 1112222 to rotate about the Z-axis by a small angle. In this way, the silicon rod 2 clamped between the fixed end clamping plate and the movable end clamping plate can rotate around the Z axis by changing the included angle between the adjusting plate 1112222 and the second bottom plate 1112221, so that the angle of the silicon rod 2 along the Z axis can be adjusted.

In one possible embodiment, the adjusting assembly further includes a second adjusting motor (third driving part) 1112224, an adjusting top block (first adjusting part, wherein the top is a form of the first adjusting structure) 1112225 and an adjusting wedge (second adjusting part, wherein the wedge is a form of the second adjusting structure) 1112226, and the present invention is mainly based on the second bottom plate 1112221, the adjusting plate 1112222 and the positioning block 1112223, and adjusts the angle of the silicon rod 2 along the Z-axis by the cooperation of the adjusting top block and the adjusting wedge. As in the present example, the second adjustment motor 1112224 is a stepping motor. In this case, the second bottom plate 1112221 is provided with an installation space at a position corresponding to the adjustment top block (a position close to the right side), and the adjustment top block 1112225 is freely accommodated in the installation space and fixed to the adjustment plate by a fastener such as a screw b 11122251.

As in this example, the upper side of the adjustment top piece is substantially an arc surface (first adjustment structure) that protrudes out of the installation space of the second bottom plate 1112221 at a position near the middle. Wherein a stepper motor is coupled to the adjust wedge 1112226 to move the adjust wedge toward/away from the adjust top block 1112225. The underside (second adjustment structure) of adjustment wedge 1112226 may be beveled, curved, or a combination thereof. In the orientation shown in the drawings, as in the present embodiment, the underside of the setting wedge is a ramp sloping downwardly from right to left.

In one possible embodiment, for example, a stepper motor can drive the adjusting wedge 1112226 to the left via the T-shaped lead screw 1112229. Preferably, a guide 1112228 matched with the movement track of the adjusting wedge block can be arranged on the second bottom plate 1112221, so that the stepping motor drives the adjusting wedge block to move leftwards along the guide by the T-shaped screw rod. In the orientation shown, the adjust wedge has a sliding end 1112227 above it that engages the guide rail, as in this example. The process of leftward movement of the adjusting wedge will push the adjusting top block to move downward, and since the adjusting top block is fixed on the adjusting plate 1112222, the adjusting plate will rotate clockwise around the positioning block 1112223. Similarly, when the stepping motor rotates in the reverse direction, the adjusting wedge 1112226 moves rightward, the adjusting top block 1112225 moves upward, and the adjusting plate 1112222 rotates counterclockwise around the positioning block 1112223.

It can be understood that, on the premise that the accuracy is satisfied, the bottom surface of the adjusting wedge block can be changed into a plane, and the advancing direction of the stepping motor is set to have a certain included angle with the second bottom plate.

Referring primarily to fig. 3 and 13, in one possible embodiment, the loading platform assembly 113 primarily includes a loading platform 1131, a loading platform 1132, and two sets of drive linkages disposed therebetween. As in this example, the driving transmission mechanism mainly includes a loading and unloading motor 11331, a first ball screw 11332 and a first rail slider 11333, and the loading and unloading motor drives the first ball screw to move under the guidance of the first rail slider and generate displacement along the X-axis direction. The two sets of driving transmission mechanisms are respectively used for driving the feeding platform 1131 and the discharging platform 1132 to move along the X-axis direction, so that the position of the silicon rod in the X-axis direction is adjusted, and the feeding process and the discharging process are completed. As in this example, an organ shield 11334 is disposed between the feeding platform and the discharging platform to perform a certain waterproof and dustproof function while ensuring that feeding and discharging can be achieved.

Referring mainly to fig. 14, in a possible embodiment, the centering assembly 112 mainly includes a third bottom plate 1121, a centering motor (not shown) disposed on the third bottom plate 1121, a rack and pinion mechanism, a clamping plate group, and a first probe group, in this example, the centering motor is a servo motor, the rack and pinion mechanism includes a gear 11240 connected to a power output shaft of the servo motor, and upper and lower racks (respectively denoted as a first rack 11241 and a second rack 11242) engaged with the gear 11240, the clamping plate group includes a first clamping plate 11251 and a second clamping plate 11252 disposed opposite to each other and respectively connected to the first rack 11241 and the second rack 11242, and the first clamping plate 11251 and the second clamping plate 11252 are respectively configured with a first probe group, wherein the first probe group includes two probes (respectively denoted as a first probe 11261 and a second probe 62) and is mainly used for detecting an adjustment amount of the posture of the silicon rod 112.

In this example, a servo motor is provided on the back side (rear side in the drawing) of the third base plate at a substantially central position, a power output shaft of the servo motor protrudes out of the front side of the third base plate and is connected with a first gear 11240, a position on the left side of an upper first rack 11241 and a position on the right side of a lower second rack 11242 are engaged with the gear 11240, respectively, and the right end of the first rack 11241 and the left end of the second rack 11242 are connected to a left first bridge 11251 and a right second bridge 11252, respectively. In operation, the feeding assembly 111 conveys the silicon rod to the position below the centering assembly 112 and stops moving, and the (first and second) clamping plates respectively move from the outer side to the inner side and stop moving after clamping the silicon rod. To ensure the stability of the movement, the base plate is provided with guide rails and the (first and second) jaws are provided with guide grooves matching the guide rails, so that the rotation of the servo motor drives the gear 11240 to rotate and the (first and second) racks move inwards by means of the engagement with the gear 11240 to move the (first and second) jaws on the guide rails.

The (first and second) clamping plates of the centering assembly 112 adjust the position of the silicon rod in the Y-axis direction, so that the (movable and fixed) chuck of the feeding slide unit 12 reaches a proper position in advance before clamping the silicon rod, and the length of the silicon rod can be measured. The first probe 11261 and the second probe 11262 of the two first probe sets determine the adjustment amount of the position and angle of the silicon rod by inspecting the rear side surface and the upper side surface of the silicon rod, respectively.

In this example, the first probe 11261 is required to calculate the outer dimension of the silicon rod 2 according to the magnitude of the amount of compression of the head portion of the first probe 11261 after the head portion thereof is protruded to hit the upper side surface of the silicon rod 2. After the completion of the inspection, it is necessary to keep the head thereof away from the upper side surface of the silicon rod 2. In order to achieve the extension and contraction of the head of the first probe 11261, for example, the first probe 11261 may be provided with a second cylinder 112611, and the second cylinder 112611 may be mounted on the first mounting plate to push the head of the first probe to extend, so that the head of the first probe may be compressed after contacting the surface of the silicon rod 2. The second probe 11262 is fixed to the second mounting plate 112523 without using a cylinder. Specifically, the second probe 11262 may be compressed by moving the silicon rod 2 toward the second probe 11262 by the loading device 11, so as to obtain the amount of compression. Namely: the detection of the rear side surface of the silicon rod by the second probe 11262 may be accomplished along with the movement of the silicon rod in the X-axis direction.

Based on this, the operating principle of the centering assembly 112 is: after the silicon rod 2 is clamped by the pair of clamping plates of the centering assembly 112 and then released, the feeding platform 1131 continues to advance for a certain distance along the X-axis direction, the two second probes 11262 are compressed, so that the external dimension (width) of the silicon rod 2 along the X-axis direction is obtained, and the width difference of the two ends of the silicon rod 2 is obtained through the pair of second probes 11262. Then, the second air cylinders 112611 corresponding to the two first probes extend to drive the heads of the two first probes 11261 to contact with the upper surface of the silicon rod and compress for a certain distance, so that the external dimension (height) of the silicon rod along the Z-axis direction is obtained, and the height difference between the two ends of the silicon rod is obtained through the pair of first probes 11261.

Thus, the movable chuck 122 can move along the Y-axis synchronously with the slide assembly via the slide drive motor 1202, or can move along the Y-axis relative to the slide assembly via the movable chuck drive system. In addition, the fixed chuck 121 and the movable chuck 122 are respectively provided with a fixed chuck rotating motor 1211 and a movable chuck rotating motor 1221 so as to rotate the silicon rod after the silicon rod is clamped by the (fixed, movable) chucks, for example, from one set of surfaces to be ground to another set of surfaces to be ground.

Referring mainly to fig. 1, 16 to 18, in one possible embodiment, the grinding device 13 mainly includes a pair of oppositely disposed rough grinding wheels 131 for rough grinding of the silicon rod 2, a pair of oppositely disposed finish grinding wheels 132 for finish grinding of the silicon rod 2, and a detection assembly 133.

In one possible embodiment, the rough grinding motor 1311 drives the fourth ball screw 1312 to drive the carriage 1314 carrying the rough grinding wheel 131 to move in the X-axis direction by the guide of the fourth rail block 1313. The detection unit 133 is mounted on a carriage 1314 for carrying the rough grinding wheel 131. For example, the finish grinding wheel 132 may be moved in a manner similar to that of the rough grinding wheel 131, and will not be described in detail.

In one possible embodiment, the inspection assembly 133 basically includes a base 1331, a base plate 1332, a slide plate 1333, a second probe set, a third air cylinder 1335 and a fifth rail slide 1336. Among them, the base plate 1332 is fixed on the base 1331, and the slide plate 1333 is disposed on the base plate 1332 through the fifth rail block 1336, for example, the second probe group includes three third probes 1334 arranged in the vertical direction and installed on the slide plate 1333. During detection, the third cylinder 1335 extends to push the sliding plate 1333 to extend along the X-axis direction, and after detection is finished, the third cylinder 1335 retracts to pull the sliding plate 1333 to retract.

Based on the structure, the utility model discloses a grinding machine 1's working process is roughly:

after the feeding device 11 finishes adjusting the pose of the silicon rod 2, and the feeding slide unit 12 reaches a predetermined position according to the length of the silicon rod measured by the centering assembly 112, the movable chuck 122 moves along the Y-axis relative to the slide unit, so that the silicon rod is clamped by the cooperation between the fixed chuck 121 and the movable chuck 122. Thereafter, the feed slide table device 12 moves along the Y axis to transport the silicon rod 2 to the grinding area, and the feed slide table device 12 moves and rotates the silicon rod along the Y axis in accordance with the program setting, and finishes the grinding. After grinding is completed, the feeding sliding table device returns to the blanking area of the feeding device 11, and at the moment, the (fixed and movable) chuck loosens the silicon rod, so that the silicon rod falls to the blanking table corresponding to the blanking area, and blanking is completed.

Before grinding, the silicon rod 2 is inspected by the inspection unit 133. Specifically, when the silicon rod 2 stops moving after reaching the first detection position, the third cylinder 1335 of the detection assembly 133 extends to push the third probe 1334 to move along the X-axis direction, and the position of the third probe 1334 is advanced relative to the grinding wheel. Then, the rough grinding wheel 131 and the detection assembly 133 continue to move in the X-axis direction by the drive of the rough grinding motor 1311 until the third probe contacts the silicon rod and detection is completed (dotting and not grinding). Along with the movement of the silicon rod along the Y-axis direction, the third probe can detect the knife inlet position, the middle position along the length of the silicon rod and the knife outlet position of the silicon rod in sequence, then the chuck drives the silicon rod to rotate 90 degrees, and the detection process is repeated.

Whether the aforementioned grinding process is performed on the silicon rod 2 is determined by the detection result of the detection means 133. Specifically, if the maximum grinding size of the silicon rod is smaller than the standard size after grinding, the size of the rod is determined to be unqualified and the rod cannot be ground, so that the rod needs to be withdrawn, namely, the silicon rod is withdrawn to the blanking platform, and then manual intervention with different degrees is performed. On the premise that the silicon rod is qualified, the position deviation and the angle deviation between the axis of the (fixed or movable) chuck and the axis of the silicon rod can be measured by measuring the three positions of the silicon through the second probe group, if the deviation related to the four dimensions (namely, the deviation belongs to the adjusting capability of the feeding device) is greater than a specified value, the silicon rod is placed (returned) on the feeding platform of the feeding device again, the pose of the silicon rod is adjusted on the feeding platform for the second time, and the silicon rod is detected again after the adjustment is completed. Such as where the deviation is a position along the Y-axis, may be adjusted by the centering assembly. This can be achieved by feeding the (stationary, movable) collet of the slide arrangement, if the deviation is an angle along the Y-axis. After the detection is finished, grinding can be started. In the detection process, the grinding amount of the rough grinding wheel 131 can be calculated, and according to the grinding amount, the rough grinding wheel advances for a certain distance towards the X axis to perform rough grinding. After the rough grinding is finished, the detection assembly repeats the previous detection process to calculate the grinding amount of the finish grinding wheel 132, and the finish grinding wheel advances a certain distance to the X axis similarly according to the grinding amount to carry out finish grinding. In the present invention, there is a direct association between the feeding assembly and the detecting assembly, so that in an optional case, the aforementioned first probe set corresponding to the centering assembly can be appropriately reduced or omitted.
