Description

An intelligent gear production device

Technical Field

The invention relates to the field of gear production, and in particular to an intelligent gear production device.

Background Art

A gear is a mechanical component with teeth on the rim that can continuously mesh to transmit motion and power. Before the production of existing gears, it is necessary to determine the gear module, number of teeth, pressure angle and other parameters, and then select the appropriate material (usually metal material such as steel) according to the use requirements of the gear. The gear is cut using lathes, milling machines and other mechanical equipment to form the gear tooth shape. The gear is then heat treated, finished and other arrangements are performed to complete the production of the gear. Existing gears need to be ground and polished during production to improve the accuracy and quality of the gear.

For example, the patent with publication number CN117283446B and publication date February 2, 2024 discloses a grinding and polishing device for wind turbine gears, including a polishing barrel, a polishing rotary barrel is concentrically rotated inside the polishing barrel, the top of the polishing barrel has an upper cover, the bottom of the upper cover is connected to a guide clamping cylinder along its axial direction, the gear is sleeved on the outside of the guide clamping cylinder, and the polishing rotary barrel drives the abrasive inside it to rotate to polish the gear. During the polishing process, the gear slides back and forth along its axial direction relative to the guide clamping cylinder to achieve grinding and polishing of the inside and outside of the gear; this patent can not only achieve grinding and polishing of the inside and outside of the gear, but also can contact with the abrasive flow at different heights inside the polishing rotary barrel, make full use of the abrasive flow as much as possible, and thus improve the grinding efficiency and quality while avoiding the waste of resources to the greatest extent.

Existing gears need to be polished after grinding, and when the gears are transferred from the grinding station to the polishing station, the gears need to undergo multiple clamping, positioning and movement during this process. Obviously, this increases the probability of defective products and affects processing efficiency.

Summary of the invention

The purpose of the present invention is to provide an intelligent gear production device to solve the technical problems in the related art.

In order to achieve the above object, the present invention provides the following technical solutions:

An intelligent gear production device includes a frame, on which a rotating unit, a fixing unit and a moving unit are installed, wherein the fixing unit is used to fix the gear, and the moving unit drives the fixing unit to move, and further includes:

a first adjusting body, on which a first threaded grinding wheel for rough grinding of the gear is disposed;

a second adjusting body, on which a second threaded grinding wheel for fine grinding the gear is disposed;

The first adjusting body is connected to the second adjusting body through a deflecting part, and the deflecting part drives the second adjusting body to drive the second threaded grinding wheel to mesh with the gear based on the rotation of the gear.

As mentioned above, a displacement sensor is also installed on the frame, and the displacement sensor is used to monitor the rotation angle of the gear. When the rotation angle of the gear reaches the established threshold of the displacement sensor, the displacement sensor sends a signal to the deflection part, and the deflection part drives the second adjustment body to drive the second threaded grinding wheel to engage with the gear based on the signal of the displacement sensor.

As mentioned above, the fixed unit is rotationally connected to the movable unit, and the rotation axis of the fixed unit is coaxial with the gear.

As mentioned above, the deflection part includes a connecting module and a triggering module. The connecting module connects the first adjusting body with the second adjusting body. The triggering module is installed on the fixing unit. When the fixing unit rotates with the gear, the triggering module contacts the connecting module, and the connecting module drives the second adjusting body to drive the second threaded grinding wheel to engage with the gear.

As mentioned above, the fixing unit is divided into a fixing part, a second rotating seat and a first rotating seat from top to bottom. The fixing part is used to fix the gear. The fixing part is rotationally connected to the first rotating seat. The first rotating seat and the second rotating seat are rotationally connected. The trigger module includes a first trigger wedge and a second trigger wedge. The first trigger wedge is installed on the side wall of the first rotating seat, and the second trigger wedge is installed on the side wall of the second rotating seat.

As mentioned above, in the initial state, the first trigger wedge and the second trigger wedge are distributed at an angle, and the second trigger wedge passes through the connection module earlier than the first trigger wedge.

As mentioned above, the connecting module includes a connecting vertical rod, a first connecting part and a second connecting part. The connecting vertical rod is vertically arranged, and a first deflection groove and a second deflection groove are sequentially opened on the connecting vertical rod from bottom to top. The first connecting part and the second connecting part are spaced apart from bottom to top on the connecting vertical rod. The first connecting part is used to drive the second adjusting body to deflect to a position close to the gear, and the second connecting part is used to drive the first adjusting body to deflect to a position away from the gear.

As mentioned above, the first connecting part includes a first sliding sleeve, which slides along the axial direction of the connecting vertical rod. A first matching wedge is installed on the side wall of the first sliding sleeve, and the first matching wedge corresponds to the first trigger wedge. A first rotating ring is rotatably installed on the upper surface of the first sliding sleeve through a torsion spring, and a first slider is fixed on the inner wall of the first rotating ring. The other end of the first slider is inserted into the first deflection groove, and the first rotating ring is connected to the second adjustment body through a connecting rod.

As mentioned above, the second connecting part includes a second sliding sleeve, which slides along the axis of the connecting vertical rod. A second matching wedge is installed on the side wall of the second sliding sleeve, and the second matching wedge corresponds to the second trigger wedge. A second rotating ring is rotatably installed on the upper surface of the second sliding sleeve through a torsion spring, and a second slider is fixedly installed on the inner wall of the second rotating ring. The other end of the second slider is inserted into the second deflection groove, and the second rotating ring is connected to the second adjustment body through a connecting rod.

As mentioned above, both the first deflection groove and the second deflection groove are inclined grooves. The first deflection groove extends obliquely downward along the surface of the connecting vertical rod from the midpoint position of the connecting vertical rod, and the second deflection groove extends obliquely upward along the surface of the connecting vertical rod from the midpoint position of the connecting vertical rod. The extension directions of the first deflection groove and the second deflection groove are opposite. When the first slider slides along the groove direction of the first deflection groove, the second adjustment body deflects the second threaded grinding wheel toward the direction of the gear. When the second slider slides along the groove direction of the second deflection groove, the first deflection body deflects the first threaded grinding wheel toward the direction away from the gear.

The beneficial effect of the present invention lies in that: in the above technical scheme, the deflection part provided by the present invention, when the gear is engaged with the first threaded grinding wheel, the first threaded grinding wheel performs rough grinding on the gear, and the gear is driven by the first threaded grinding wheel to rotate with its own axis as the center of the circle, at this time, the deflection part drives the second adjustment body to drive the second threaded grinding wheel to engage with the gear, so that the area of the gear after rough grinding just falls into the position of the second threaded grinding wheel, and the area of the gear after rough grinding is finely ground, and the gear rough grinding and fine grinding are completed at one time, thereby improving the processing efficiency of the gear.

DETAILED DESCRIPTION

In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with Figures 1 to 12.

In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "degree", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

In one embodiment of the present invention, an intelligent gear production device is provided, including a frame 1, on which a rotating unit 2, a fixing unit 3 and a moving unit 4 are installed, the fixing unit 3 is used to fix the gear, the fixing unit 3 includes a placement seat, and the placement seat is provided with a locking part for fixing the gear. In this embodiment, the locking part can be selected from internal clamping jaws, and the internal clamping jaws fix the gear through its center hole by internal clamping. The moving unit 4 drives the fixing unit 3 to move, and also includes:

A first adjusting body 5 on which a first threaded grinding wheel 6 for rough grinding of the gear is disposed;

A second adjustment body 7, on which a second threaded grinding wheel 8 for fine grinding of the gear is arranged;

Among them, the first adjusting body 5 and the second adjusting body 7 are both rod-shaped, the first threaded grinding wheel 6 is coaxially arranged with the first adjusting body 5, and the second threaded grinding wheel 8 is also coaxially arranged with the second adjusting body 7. Here, fine grinding and coarse grinding do not refer to specific precisions, but mean that the grinding precisions of the first threaded grinding wheel 6 and the second threaded grinding wheel 8 are different, and the grinding precision of the second threaded grinding wheel 8 is higher than the grinding precision of the first threaded grinding wheel 6. Obviously, the specific precision of the technicians in this field can be selected based on actual needs. The moving unit 4 can use two groups of linear drive mechanisms. One group of linear drive mechanisms drives the fixed unit 3 to move in the horizontal direction, approaching the direction of the first adjusting body 5, driving the gear on the fixed unit 3 to cooperate with the first threaded grinding wheel 6, and the other group of linear drive mechanisms drives the fixed unit 3 to move in the vertical direction, driving the fixed The gear on the unit 3 moves up and down relative to the first threaded grinding wheel 6, driving a target (fixed unit 3) to move horizontally and vertically is a prior art, and its specific structure is not described in detail. The first adjustment body 5 and the second adjustment body 7 are connected by a deflection part 9. The deflection part 9 drives the second adjustment body 7 to drive the second threaded grinding wheel 8 to engage with the gear based on the rotation of the gear. The rotating unit 2 is used to drive the first adjustment body 5 to rotate around its own axis and the second adjustment body 7 can also rotate around its own axis. Specifically, in this embodiment, the rotating unit 2 can use two groups of drive motors, one group of drive motors is connected to the first adjustment body 5, and the other group of drive motors is connected to the second adjustment body 7. The two drive motors respectively drive the first adjustment body 5 and the second adjustment body 7 to rotate with their own axes as the center of the circle. This is a prior art and is not described in detail here.

It should be noted that the first threaded grinding wheel 6 and the second threaded grinding wheel 8 are always at the same horizontal height. In the initial state, the first threaded grinding wheel 6 and the second threaded grinding wheel 8 are located on one side of the gear blank (as shown in FIG. 1 ). When the gear blank needs to be finely ground, the second threaded grinding wheel 8 is deflected toward the gear under the action of the deflection part 9, forming a right angle to wrap around the gear (as shown in FIG. 2 ).

Specifically, manual or mechanical equipment places the gear blank to be processed on the placement seat of the fixing mechanism, and then the inner clamping claw on the placement seat fixes the gear in an inner clamping manner, and the driving motor first drives the first adjusting body 5 to rotate with its own axis as the center of the circle, and at this time, the first adjusting body 5 drives the first threaded grinding wheel 6 to rotate synchronously, and the moving unit 4 drives the gear on the fixing unit 3 to contact the first threaded grinding wheel 6. As the first threaded grinding wheel 6 rotates, the gear rotates with its own axis as the center of the circle under the action of the first threaded grinding wheel 6 (similar to the cooperation of a worm gear) to achieve rough grinding, and during the rough grinding of the gear by the first threaded grinding wheel 6, Another set of linear drive mechanisms as the mobile unit 4 drives the fixed unit 3 to reciprocate in the vertical direction, and the adjusting gear contacts with the first threaded grinding wheel 6 at contact areas at different heights to complete the rough grinding of the gear. After the rough grinding of the gear is completed, the deflection unit 9 drives the second adjusting body 7 to deflect toward the gear, driving the second threaded grinding wheel 8 on the second adjusting body 7 to contact and mesh with the gear. The deflection unit 9 here can use a stepper motor, which is connected to the second adjusting body 7 through the stepper motor, wherein the output end of the stepper motor is rotatably connected to the second adjusting body 7, that is, the second adjusting body 7 can rotate with its own axis relative to the stepper motor. The second adjusting body 7 rotates with its own axis as the center of the circle. When the deflection unit 9 drives the second threaded grinding wheel 8 on the second adjusting body 7 to engage with the gear, the second adjusting body 7 rotates with its own axis as the center of the circle under the action of the drive motor connected thereto (it should be noted that the speeds of the two drive motors should be consistent. The speed control of the two drive motors is a prior art and will not be described in detail later). The gear rotates with its own axis as the center of the circle under the engagement of the first threaded grinding wheel 6, and the rotating gear engages with the second threaded grinding wheel 8. At this time, the second threaded grinding wheel 8 also rotates under the action of the drive motor and engages with the gear. At this time, the gear embryo is roughly ground by the first threaded grinding wheel 6. After that, it comes into contact with the second threaded grinding wheel 8, and the second threaded grinding wheel 8 fine-grinds the gear blank, thereby completing the processing of the gear blank. However, the gear blank has a certain thickness. When the gear passes through the first threaded grinding wheel 6 and the second threaded grinding wheel 8 as in the above process, only the area where the circumference of the gear blank is in contact with the first threaded grinding wheel 6 and the second threaded grinding wheel 8 can be processed, and the remaining uncontacted areas remain in an unprocessed state. Then, after the gear blank rotates one circle, the moving unit 4 is cooperated to drive the gear blank to move in the vertical direction along its own axis, and the contact area between the gear blank and the first threaded grinding wheel 6 and the second threaded grinding wheel 8 is adjusted to achieve rough grinding and fine grinding of the gear.

Preferably, in this embodiment, when processing a gear blank with a certain thickness, the middle layer of the gear blank is processed first (that is, when the gear is placed horizontally, a circle at the midpoint of the thickness of the gear blank is the middle layer of the gear blank). After the middle layer of the gear blank is rough-ground and fine-ground, the middle layer of the gear blank will be shorter than the remaining unprocessed parts. Therefore, after the gear blank moves vertically along its own axis, when the remaining parts (the area above the middle layer of the gear blank or the area below the middle layer of the gear blank) are processed, the middle layer of the area to be processed facilitates the removal of the ground material from the surface to be processed and allows the cooling medium (such as coolant, cooling gas) to enter, thereby improving the heat exchange efficiency between the processing area and the cooling medium, that is, improving the heat dissipation efficiency of the area to be processed, and further improving the processing quality.

Among them, in this embodiment, the rotation of the second adjustment body 7 is based on the control of the deflection part 9, so it is easy for the gear to idle for multiple turns (that is, the gear has been roughly ground and the fine grinding has not been intervened in the first time, which affects the processing efficiency of the gear). Preferably, a displacement sensor 11 is also installed on the frame 1. The displacement sensor 11 is used to monitor the self-rotation angle of the gear (the self-rotation angle refers to the angle from the start of the gear being stationary to the gear self-rotating under the drive of the first threaded grinding wheel 6. Monitoring the self-rotation angle of the gear by the displacement sensor 11 is a prior art and is not described in detail here). When the self-rotation angle of the gear reaches the established threshold of the displacement sensor 11, the displacement sensor 11 sends a signal to the deflection part 9. The deflection part 9 drives the second adjustment body 7 to drive the second threaded grinding wheel 8 to mesh with the gear based on the signal of the displacement sensor 11. It should be noted that after the second adjustment body 7 completes the deflection under the action of the deflection part 9, the second adjustment body 7 and the first adjustment body 5 are directly arranged at an angle of ninety degrees. The setting of the monitoring threshold of the displacement sensor 11 should be It can be less than ninety degrees, but there is a certain time difference from the time when the displacement sensor 11 sends a signal to the time when the second adjustment body 7 is in place with the second threaded grinding wheel 8. During this time difference, the gear embryo will still rotate under the action of the first threaded grinding wheel 6. In order to ensure the timing of the cooperation between the second threaded grinding wheel 8 and the gear embryo, the setting of the threshold of the displacement sensor 11 is based on the rotation speed of the gear, that is, when the gear embryo rotates faster under the action of the first threaded grinding wheel 6, the smaller the threshold of the displacement sensor 11; when the gear embryo rotates slower under the action of the first threaded grinding wheel 6, the larger the threshold of the displacement sensor 11. The threshold of the displacement sensor 11 is used to control the deflection timing of the second adjustment body 7. In this embodiment, the threshold of the displacement sensor 11 is preferably 45°, that is, when the gear embryo rotates under the action of the first threaded grinding wheel 6 and the gear embryo rotates 45°, the monitoring threshold of the displacement sensor 11 is reached, and the displacement sensor 11 sends a signal to the deflection part 9, and the deflection part 9 drives the second adjustment body 7 to deflect toward the gear embryo.

Specifically, the gear blank processing process includes the following steps:

Rough grinding: The gear embryo is fixed on the placement seat by the fixing unit 3, and the moving unit 4 meshes with the first threaded grinding wheel 6 with the gear embryo. Then the driving motor drives the first adjusting body 5 to rotate with its own axis as the center of the circle. The first threaded grinding wheel 6 rotates synchronously with the first adjusting body 5. The first threaded grinding wheel 6 is in contact and meshing with the gear embryo. The first threaded grinding wheel 6 performs rough grinding on the contact area between the first threaded grinding wheel 6 and the gear embryo.

Fine grinding: When the first threaded grinding wheel 6 performs rough grinding on the gear blank, the gear blank rotates with its own axis as the center under the meshing action of the first threaded grinding wheel 6. As the gear blank starts to rotate, the displacement sensor 11 also synchronously monitors the rotation angle of the gear. When the gear rotates 45° (the 45° here is not a constant value, and the 45° is only an example), the displacement sensor 11 sends an electrical signal to the deflection unit 9, and the stepper motor of the deflection unit 9 drives the second adjustment body 7 to deflect in the direction of the gear blank until the second adjustment body 7 is on the gear blank. The second threaded grinding wheel 8 contacts the gear embryo. At this time, the area of the gear embryo that contacts the second threaded grinding wheel 8 should be exactly the area that has been rough-ground. Subsequently, the second threaded grinding wheel 8 also rotates at the same speed as the first threaded grinding wheel 6 under the action of the driving motor. The second threaded grinding wheel 8 contacts the gear embryo and promptly performs fine grinding on the area of the gear embryo that has been rough-ground, thereby avoiding the idling of the gear embryo after rough grinding and the inability to perform fine grinding on the area of the gear embryo that has been rough-ground in the first place, thereby improving the processing efficiency of the gear embryo and saving processing time.

It should be noted that when processing existing gears, the machine tool often sprays cooling medium (such as cooling water, cooling oil, etc.) to the processing position, and continuously sprays cooling medium to the processing area of the gear. A large amount of cooling medium directly immerses the displacement sensor 11. The displacement sensor 11 is in contact with the cooling medium for a long time, and is prone to aging, resulting in insensitivity. In this regard, in another embodiment of the present invention, the fixed unit 3 is rotatably connected to the mobile unit 4, and the rotation axis of the fixed unit 3 is coaxial with the gear. The fixed unit 3 is divided into a fixed portion 31 and a first rotating seat 32 from top to bottom along the vertical direction (that is, the axis direction of the gear), and the fixed unit 3 is The part 31 is used to fix the gear, and the fixing part 31 is rotatably connected with the first rotating seat 32. The deflection part 9 includes a connecting module 91 and a triggering module 92. The triggering module 92 includes a first triggering wedge 921, and the first triggering wedge 921 is fixedly installed on the side wall of the first rotating seat 32. The connecting module 91 includes a connecting vertical rod 93 and a first connecting part 94. The connecting vertical rod 93 is vertically arranged, and a first deflection groove 931 is provided on the connecting vertical rod 93. The first connecting part 94 is used to drive the second adjusting body 7 to deflect to a position close to the gear. The first connecting part 94 includes a first sliding sleeve 941, and the first sliding sleeve 941 is connected along the connecting vertical rod 93. Axial sliding, a first matching wedge block 942 is installed on the side wall of the first sliding sleeve 941, and the first matching wedge block 942 corresponds to the first trigger wedge block 921 (and the contact surface between the first matching wedge block 942 and the first trigger wedge block 921 is arc-shaped), and a first rotating ring 943 is rotatably installed on the upper surface of the first sliding sleeve 941 through a torsion spring, and a first slider 944 is fixed on the inner wall of the first rotating ring 943, and the other end of the first slider 944 is inserted into the first deflection groove 931, and the upper surface of the first rotating ring 943 is connected to a self-rotating ring 946 through a telescopic rod 945, and the self-rotating ring 946 is rotatably installed on the outer side of the connecting vertical rod 93 (need It should be noted that, in the present embodiment, the self-rotating ring 946 can only rotate with the axis of the connecting vertical rod 93 as the center, and cannot move along the axial direction of the connecting vertical rod 93, such as: an annular groove is provided on the side wall of the connecting vertical rod 93, the annular groove is coaxially arranged with the connecting vertical rod 93, an annular protrusion is provided on the inner circumferential surface of the self-rotating ring 946, and the annular protrusion is inserted into the annular groove), the self-rotating ring 946 is connected to the second adjustment body 7 through a connecting rod, and the first deflection groove 931 is an inclined groove, and the first deflection groove 931 extends obliquely downward from the midpoint position of the connecting vertical rod 93 (that is, the middle position in the axial direction of the connecting vertical rod 93) along its surface.

It should be noted that, in this embodiment, the fixing portion 31 and the first rotating seat 32 have the following two working modes:

One is that the first rotating seat 32 is not subject to additional resistance, so that the fixing portion 31 and the first rotating seat 32 rotate synchronously under the action of friction force;

The second is: the additional resistance to the first rotating seat 32 is greater than the friction force, so that the first rotating seat 32 stops rotating, and only the fixed part 31 rotates (the end of the first rotating seat 32 can be provided with an annular avoidance groove, the bottom of the fixed part 31 is annular and inserted into the avoidance groove, and the matching parts of the two are provided with an elastic damping structure. The most common elastic damping structure is: a limiting groove is provided on the side wall of the avoidance groove along the circumferential direction, and both ends of the limiting groove are arc-shaped, and a limiting block is connected to the side wall of the fixed part 31 through a spring, one end of the limiting block is inserted into the limiting groove, and the head end of the limiting block is hemispherical. In the initial state, the head end of the limiting block is inserted into the limiting groove, and the limiting block is against the limiting groove. The end portion realizes elastic damping in this way. At this time, when the first rotating seat 32 is not subjected to additional resistance, as the fixed portion 31 rotates, the limit block will not leave the limiting groove, and then the fixed portion 31 and the first rotating seat 32 rotate synchronously; when the first rotating seat 32 is subjected to additional resistance greater than the friction between the limit block and the limiting groove, the additional resistance prevents the first rotating seat 32 from continuing to rotate, but as the fixed portion 31 continues to rotate, the limit block moves relative to the limiting groove, so that under the extrusion of the limiting groove, the spring connected to the limit block is squeezed and contracts, and the limit block leaves the limiting groove and enters into the avoidance groove of the first rotating seat 32. At this time, the fixed portion 31 rotates along the avoidance groove on the first rotating seat 32).

Specifically, when the gear rotates under the action of the first threaded grinding wheel 6, the first rotating seat 32 is not subjected to external force, and the gear rotates synchronously with the fixing portion 31 and the first rotating seat 32. When the first rotating seat 32 rotates, the first trigger wedge 921 on the first rotating seat 32 moves synchronously with the first rotating seat 32, and the two arc-shaped surfaces of the first trigger wedge 921 and the first matching wedge 942 squeeze each other. Because the first rotating seat 32 cannot move in the vertical direction, but the first sliding sleeve 941 can move in the vertical direction along the axis of the connecting vertical rod 93, the first matching wedge 942 will move downward in the vertical direction under the squeezing action of the first trigger wedge 921. On the circumference of the first rotating seat 32, the thickness of the first trigger wedge 921 (the size in the radial direction of the first rotating seat 32) gradually increases, so that its rotation can gradually squeeze the first matching wedge 942. 2 moves downward synchronously with the first sliding sleeve 941. During the downward movement of the first sliding sleeve 941, the first rotating ring 943 moves downward synchronously with the first sliding sleeve 941. During the downward movement of the first rotating ring 943, the first sliding block 944 on the inner wall of the first rotating ring 943 slides along the groove direction of the first deflection groove 931. At this time, the first rotating ring 943 rotates relative to the first sliding sleeve 941. Then, while the first rotating ring 943 moves downward, it rotates along the axis of the connecting vertical rod 93 as the center of the circle. As the first rotating ring 943 moves downward, the telescopic rod 945 connected to the rotating ring 946 is stretched (ensuring that the height of the rotating ring 946 remains unchanged). When the first rotating ring 943 rotates, under the connection of the telescopic rod 945, the rotating ring 946 rotates synchronously with the first rotating ring 943. Then, under the connection of the connecting rod on the rotating ring 946, the second adjusting body 7 deflects synchronously with the first rotating ring 943. The main body 7 of the joint deflects with the second threaded grinding wheel 8 toward the direction of the gear, so that the second threaded grinding wheel 8 is in meshing contact with the gear, so that the gear after rough grinding is immediately fine-ground, thereby improving the processing efficiency of gear processing. When the gear rotates one circle relative to the second threaded grinding wheel 8 (that is, the gear rotates 360° with its own axis as the center), the rotating unit 2 that drives the first threaded grinding wheel 6 and the second threaded grinding wheel 8 to rotate stops working, and then the processed gear is removed from the fixing part 31 by manual or mechanical equipment to complete the gear unloading process. The stopping time of the rotating unit 2 here can be achieved by a sensor such as a high-speed camera. When the high-speed camera observes that the gear has rotated one circle relative to the second threaded grinding wheel 8, it sends a signal to the rotating unit 2, and the rotating unit 2 stops working; finally, the manual or automatic equipment rotates the first rotating seat 32 in the opposite direction (the reverse rotation here is relative to the rotation direction of the gear, that is, when the gear is in the first When the first rotating seat 32 is rotated clockwise under the action of a threaded grinding wheel 6, during the subsequent reset, the first rotating seat 32 is driven by manual or automatic equipment to rotate counterclockwise, and vice versa); the first trigger wedge 921 on the first rotating seat 32 moves away from the first matching wedge 942 on the first sliding sleeve 941, and then the first matching wedge 942 loses the squeezing of the first trigger wedge 921. At this time, the telescopic rod 945 connecting the self-rotating ring 946 and the first rotating ring 943 begins to reset and shrink. The telescopic rod 945 pulls the first rotating ring 943 and the first sliding sleeve 941 to slide upward synchronously. When the first rotating ring 943 slides upward, the first slider 944 on the inner wall of the first rotating ring 943 slides back along the groove of the first deflection groove 931. At the same time, under the action of the torsion spring, the first rotating ring 943 restores the self-rotating ring 946 to the initial state, that is, the second adjustment body 7 is deflected in the direction away from the gear to complete the reset action.

It should be noted that, in the above-mentioned embodiment, the gear is finely ground after rough grinding. In order to complete the fine grinding of the entire circumference of the gear, the gear needs to rotate at least one circle relative to the second threaded grinding wheel 8 (the gear rotates 360° with its own axis as the center) starting from when the gear leaves the first threaded grinding wheel 6 used for rough grinding and contacts the second threaded grinding wheel 8 for fine grinding. Since the first threaded grinding wheel 6 used for rough grinding and the second threaded grinding wheel 8 used for fine grinding are spaced apart (in this embodiment, the contact area of the deflected second threaded grinding wheel 8 and the first threaded grinding wheel 6 is 90°), when the gear rotates relative to the second threaded grinding wheel 8 When the gear rotates one circle, the number of revolutions relative to the first threaded grinding wheel 6 must be greater than one circle, that is, the area that was initially finely ground by the second threaded grinding wheel 8 contacts the first threaded grinding wheel 6 used for rough grinding again, that is, the finely ground gear surface is rough-ground again, destroying the original finely ground surface of the gear. In another embodiment of the present invention, the contact surface between the second trigger wedge block 922 and the second matching wedge block 953 is also arc-shaped (wherein the structure of the second trigger wedge block 922 and the second matching wedge block 953 is consistent with the structure of the first trigger wedge block 921 and the first matching wedge block 942 in the previous embodiment), and the fixed The unit 3 also includes a second rotating seat 33, the second rotating seat 33 is located above the first rotating seat 32, and the first rotating seat 32 is rotatably connected to the second rotating seat 33. The trigger module 92 also includes a second trigger wedge 922, and the second trigger wedge 922 is rotatably mounted on the side wall of the second rotating seat 33. The first trigger wedge 921 is also rotatably mounted on the side wall of the first rotating seat 32. Because the first rotating seat 32 and the second rotating seat 33 are coaxial, when the first trigger wedge 921 rotates on the first rotating seat 32, the first trigger wedge 921 rotates around the axis of the first rotating seat 32, and the second trigger wedge When the first trigger wedge 921 rotates on the second rotating seat 33, the second trigger wedge 922 rotates around the axis of the second rotating seat 33, that is, the first trigger wedge 921 and the second trigger wedge 922 rotate around the same axis on the first rotating seat 32 and the second rotating seat 33 respectively (for example, an annular groove is provided on the side wall of the first rotating seat 32, the annular groove is coaxial with the gear, the first trigger wedge 921 is damped and slidably installed in the annular groove, and the second trigger wedge 922 and the second rotating seat 33 are also connected in the above manner). In this embodiment, in the initial state, the first trigger wedge 921 and the second trigger wedge 922 are connected to each other. That is, the two are not collinear vertically upward, and the first trigger wedge 921 passes the relative position with the connecting module 91 earlier than the second trigger wedge 922 (the relative position here is recorded as the trigger position, and the first trigger wedge 921 and the second trigger wedge 922 and the trigger position of the connecting module 91 are arranged collinearly in the vertical direction), and in the initial state, the trigger position is located between the first trigger wedge 921 and the second trigger wedge 922, and the angle between the second trigger wedge 922 and the trigger position is close to zero. As the second rotating seat 33 rotates, the second trigger wedge 922 gradually moves away from the trigger position The connection module 91 further includes a second connection portion 95, which is located above the first connection portion 94, and is connected to the first adjustment body 5. The second connection portion 95 is used to drive the first adjustment body 5 to deflect to a position away from the gear. A second deflection groove 932 is also provided on the connection vertical rod 93, and the second deflection groove 932 is located above the first deflection groove 931. The second deflection groove 932 is also an inclined groove. The second deflection groove 932 extends upward along the surface of the connection vertical rod 93 from the midpoint position. When the second slider 955 slides along the groove direction of the second deflection groove 932, the first adjustment body 5 With the first threaded grinding wheel 6 deflected in the direction away from the gear, the second connecting part 95 includes a second sliding sleeve 951, the second sliding sleeve 951 slides along the axis of the connecting vertical rod 93, a second matching wedge block 953 is installed on the side wall of the second sliding sleeve 951, the second matching wedge block 953 corresponds to the second trigger wedge block 922, a second rotating ring 954 is rotatably installed on the upper surface of the second sliding sleeve 951 through a torsion spring, a second sliding block 955 is fixedly installed on the inner wall of the second rotating ring 954, the other end of the second sliding block 955 is inserted into the second deflection groove 932, and the second rotating ring 954 is connected to the first adjusting body through a connecting rod. 5, two blocking blocks 96 are further arranged on the side wall of the connecting vertical rod 93, one blocking block 96 corresponds to the first trigger wedge block 921, and the other blocking block 96 corresponds to the second trigger wedge block 922. When the first matching wedge block 942 moves down to the maximum position, the blocking block 96 corresponding to the first trigger wedge block 921 blocks the first matching wedge block 942 to prevent the first matching wedge block 942 from continuing to move. Similarly, when the second matching wedge block 953 moves up to the maximum position, the blocking block 96 corresponding to the second matching wedge block 953 blocks the second matching wedge block 953 to prevent the second matching wedge block 953 from continuing to move.

Specifically, when the gear rotates under the action of the first threaded grinding wheel 6, the gear rotates synchronously with the fixing portion 31 and the first rotating seat 32. When the first rotating seat 32 rotates, the first trigger wedge 921 on the first rotating seat 32 moves synchronously with the first rotating seat 32. When the first trigger wedge 921 contacts the first matching wedge 942, as the first trigger wedge 921 squeezes the first matching wedge 942, the first matching wedge 942 moves downward in the vertical direction under the squeezing action of the first trigger wedge 921. When the first matching wedge 942 moves down to the lowest position, the first trigger wedge 921 is blocked by the corresponding blocking block 96. Then the first trigger wedge 921 rotates around the axis of the first rotating seat 32 on the side wall of the first rotating seat 32, and as the first The matching wedge block 942 moves downward, and the first matching wedge block 942 moves downward synchronously with the first sliding sleeve 941. During the downward movement of the first sliding sleeve 941, the first rotating ring 943 moves downward synchronously with the first sliding ring 941. The first sliding block 944 on the inner wall of the first rotating ring 943 slides along the groove direction of the first deflection groove 931. At this time, the first rotating ring 943 rotates relative to the first sliding sleeve 941, and then the first rotating ring 943 moves downward while rotating along the axis of the connecting vertical rod 93 as the center of the circle. As the first rotating ring 943 moves downward, the telescopic rod 945 connected to the rotating ring 946 is stretched (to ensure that the height of the rotating ring 946 remains unchanged), and when the first rotating ring 943 rotates, under the connection of the telescopic rod 945, the rotating ring 946 follows the first rotating ring 943. The first rotating ring 943 rotates synchronously, and then under the connection action of the connecting rod on the rotating ring 946, the second adjusting body 7 deflects synchronously with the first rotating ring 943, and the second adjusting body 7 deflects toward the direction of the gear with the second threaded grinding wheel 8, so that the second threaded grinding wheel 8 engages with the gear, so that the gear after rough grinding is immediately fine-ground. After the gear rotates one circle relative to the first threaded grinding wheel 6 (that is, when the gear rotates 360 degrees around its own axis), the second trigger wedge block 922 moves to a position relative to the connecting module 91, and the second trigger wedge block 922 squeezes the second matching wedge block 953 for the first time. The second matching wedge block 953 moves upward in the vertical direction under the squeezing action of the second trigger wedge block 922. When the second trigger wedge block 922 moves to the highest position, the second The trigger wedge block 922 is blocked by the corresponding blocking block 96, and then the second trigger wedge block 922 rotates around the axis of the second rotating seat 33 on the side wall of the second rotating seat 33. During the upward movement, the second sliding sleeve 951 moves upward synchronously with the second rotating ring 954, and the second sliding block 955 on the inner wall of the second rotating ring 954 also slides along the groove direction of the second deflection groove 932. At this time, the second rotating ring 954 rotates relative to the second sliding sleeve 951, so that under the connecting action of the connecting rod, the first adjusting body 5 deflects synchronously with the second rotating ring 954, and the first adjusting body 5 deflects with the first threaded grinding wheel 6 in the direction away from the gear, so that the first threaded grinding wheel 6 is separated from the gear, thereby avoiding the situation where the gear after fine grinding is subjected to rough grinding again, which affects the progress of gear processing.
