Description

Clamping assembly and grinding machine comprising same

Technical Field

The utility model relates to a precision adjustment technical field of material loading ring festival in equipment such as grinding machine specifically provides a centre gripping subassembly with adjustable and including the grinding machine of this centre gripping subassembly.

Background

The grinding machine is equipment for grinding hard and brittle materials. Such as grinding machines, typically include a loading assembly, a feeding assembly, and a grinding assembly. Taking a piece made of hard and brittle materials as a silicon rod as an 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 the other chuck is a fixed chuck. And the silicon rod is conveyed to the grinding component through the axial movement of the silicon rod, so that the first group of surfaces to be ground is 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.

Taking the hard and brittle material as an example of the silicon rod, since the specifications of the silicon rods are different and the external dimensions of the silicon rods of the same specification are different, when the silicon rods are placed on the loading 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 present invention is directed to solve the above technical problem at least in part, and particularly, to suppress or eliminate any link in the above positional deviation and angular deviation, thereby improving the processing efficiency of a grinding machine and the surface quality of a silicon rod on this basis. More specifically, the present invention primarily adjusts the angle between the silicon rod and (the clamping plate of) the clamping second end assembly and/or the clamping first end assembly in angular deviations. If the clamping second end component and the clamping first end component can be both movable ends or one can be a fixed end and the other can be a movable end.

In a first aspect, the present invention provides a clamping assembly, comprising: clamping the first end assembly; the clamping second end assembly is used for clamping a workpiece to be machined between the clamping first end assembly and the clamping second end assembly; and an adjustment assembly, comprising: the clamping second end component and/or the clamping first end component are/is movably arranged on the bottom plate; a drive member operatively connected to the respective clamping first end assembly or the clamping second end assembly to: under the driving of the driving part, the distance between the corresponding clamping first end assembly or the corresponding clamping second end assembly and different parts of the bottom plate is different, and the first end assembly is clamped.

With such a configuration, fine adjustment of the angle of the silicon rod waiting workpiece to be ground can be realized along the clamping direction.

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.

It should be noted that the drive connection in "the drive member is in drive connection with the elevator wheel" is to be understood as: when the 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 driving component. For example, the driving component and the lifting wheel can be in direct driving connection or indirect driving connection.

It should be noted that the operative connection of the "drive member with the respective clamping first end assembly or clamping second end assembly" is to be understood as: when the drive member acts with one of the respective clamping second end assembly or clamping first end assembly, the other concomitantly produces an action associated with that action, i.e. the two have an association at the operational level, e.g. may be a direct association or an indirect association between the two.

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

The present invention will be described below with reference to a part or all of fig. 1 to 17.

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 opened silicon rod 2 is not flat, as is usually the case: the middle part of the silicon rod is convex compared with 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 cut end surface of the diamond wire is larger than that of the square of the cut end surface of the diamond wire). Therefore, the cut silicon rod needs to be ground to an ideal rectangular parallelepiped of 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 feeding slide unit 12 after the silicon rod is adjusted to a proper 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. In case the feeding accuracy is up to standard, the ideal axis of the silicon rod 2 and the axis between the (stationary, movable) chucks should have a high 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 are required to adjust the position and posture (hereinafter referred to as pose) of the silicon rod 2 in the aforementioned four dimensions, the centering assembly 112 is used to mainly determine the adjustment amount of the feeding assembly 111 to the pose of the silicon rod 2. 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 6, in one possible embodiment, the lifting assembly 1111 mainly includes a first base plate 11111, an electric cylinder 11112, a driving plate 11113 as a driving part, a lifting wheel set including a first lifting wheel 111141 (e.g., the first lifting wheel includes two wheel units provided on a first wheel axle 111191) and a second lifting wheel 111142, and a supporting plate 11115, wherein the driving plate 11113 has inclined surfaces 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 connection between the power output end of the electric cylinder 11112 and the transmission plate 11113 is as follows: the first bottom 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 bottom 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 end 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 end 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 addition, the two lifting wheels mounted on the supporting board 11115 can roll along the inclined plane 111131 from right to left, i.e. from low to high, and the supporting board 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 end 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 uneven is: the middle portion of the silicon rod is convex compared to the two end portions. In order to enable a silicon rod having this property to be placed on the support plate more smoothly, the middle portion of the support plate is recessed farther away from the silicon rod than both sides, i.e., downward in the drawing.

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 sites provided on the support plate, the screw is provided at a position corresponding to the mounting site, and in a mounted state, the screw is completely accommodated at the mounting site 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 supporting plate 11115, and a return spring 1118 is further provided between the first base plate and the supporting 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 pallet 11115 is raised, the return spring 1118 is in a compressed/extended (e.g., 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 open-bottomed enclosure structure, the aforementioned support plate is provided on the top of the enclosure structure, and the elevating wheels are provided on the side of the enclosure structure. Illustratively, the two lifting wheels are mounted to the pallet 11115 in such a way that: first 111141 and second 111142 lift wheels are mounted to the sides of the housing structure by first 111191 and second 111192 axles, 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. Such as to enable the supporting plate and the silicon rod arranged on the supporting plate to be smoothly lifted in the same height in the whole length range.

On the basis, in order to enable the lifting assembly to have the function of adjusting the angle adjustment of the silicon rod along the X axis besides the function of adjusting the position adjustment of the silicon rod along the Z axis. The utility model discloses in, improve the function of lifting subassembly 1111.

In one possible embodiment, one of first axle 111191 and second axle 111192 may be modified to be an eccentric axle, such as first axle 111191 corresponding to first lift wheel 111141 modified to be an eccentric axle (the outer circle of the axle is parallel to and does not coincide with the axis of the outer circle) and configured with first adjustment motor 1111, such as a first adjustment motor coupled 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 accordance with this, the joint bearing 11171 is mounted on the connecting shaft 1117, so that the connecting shaft is provided to restrict the movement of the pallet 11115 in the X-axis and Y-axis directions, but not to restrict the rotation of the pallet 11115 about the X-axis. In actual products, 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.

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, for example, both the clamping movable end assembly and the clamping fixed end assembly can be movably disposed.

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 and 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 that the movable clamping plate 111215 is pushed 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 arranged along the Y-axis direction to be 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 has a reference surface (e.g., referred to as 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 adjusting the angle of the silicon rod along the Z axis.

In one possible embodiment, the adjusting assembly mainly includes a second base plate (base plate) 1112221, an adjusting 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 adjusting plate 1112222 is fixed on the fixed clamping plate on one side thereof, and the adjusting plate 1112222 is mounted on the second base plate 1112221 on the other side thereof (near the left side) by the positioning block 1112223. A gap is formed 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 (driving part) 1112224, an adjusting top block (a first adjusting part, wherein the top is a form of the first adjusting structure) 1112225 and an adjusting wedge (a 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 this example, the second trim motor 1112224 is a stepper 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 the present example, the upper side of the adjustment top block is substantially an arc surface (first adjustment structure), and a position of the arc surface near the middle portion protrudes out of the installation space of the second bottom plate 1112221. Wherein, a stepping motor is connected with the adjusting wedge 1112226 so as to push the adjusting wedge to move towards/away from the adjusting 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 can be arranged on the second bottom plate 1112221, so that the stepping motor drives the adjusting wedge to move leftwards along the guide by the T-shaped lead screw, and in this example, the upper part of the adjusting wedge has a sliding end 1112227 matched with the guide. The process of the 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 opposite 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.

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 end 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. During 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. In order to ensure the stability of the movement, the base plate is provided with a guide rail, and the (first and second) clamping plates are provided with guide grooves matched with the guide rail, so that the servo motor rotates to drive the gear 11240 to rotate, and the (first and second) racks move inwards in a manner that the (first and second) clamping plates move on the guide rail by means of meshing with the gear 11240.

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 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 finishing grinding wheel 132 may move in a manner similar to that of the rough grinding wheel 131, and will not be described herein.

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.

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 table device 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 table assembly, 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 a blanking platform 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 position of the knife entrance of the silicon rod, the middle position along the length of the silicon rod and the position of the knife exit of the silicon rod in sequence, and then the chuck drives the silicon rod to rotate by 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. Particularly, 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, the rod cannot be ground, 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 directly adjusted for the second time on the feeding platform, and the silicon rod is detected again after the adjustment is completed. Such as where the offset 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 alternative case, the aforementioned first probe set corresponding to the centering assembly can also be reduced or omitted appropriately.

It can be seen that the utility model discloses an among the loading attachment of grinding machine, realized the position control along the Z axle to the silicon rod through the cooperation of driving plate, connecting axle and the lifting wheel in the lifting subassembly. On the basis, by configuring an eccentric shaft for one of the lifting wheels, the silicon rod can be simultaneously adjusted in angle along the X axis by the lifting assembly. Through increasing the adjusting part for the centre gripping stiff end subassembly of centre gripping subassembly, realized fixing to the adjusting plate on the stiff end grip block around the rotation of locating piece based on the cooperation of adjustment voussoir and adjustment kicking block to realized the angular adjustment along the Z axle to the silicon rod. The feeding table component is added to enable the position of the silicon rod to be adjusted along the X axis in the moving process of the feeding component holding the silicon rod. Based on the utility model discloses a scheme can realize the adjustment of four dimensions to the silicon rod through loading attachment, combines the position control along the Y axle that realizes through the centering subassembly and the angular adjustment along the Y axle that realizes through (decide) the chuck to the material loading precision of grinding machine has been guaranteed.
