Description

Technical Field

[0001] This application relates to the technical field of bearing processing equipment, and in particular to an automatic bearing grinding equipment. Background Technology

[0002] A bearing is a mechanical component primarily used to support a shaft, allowing it to rotate. Bearings are indispensable parts in mechanical equipment, playing a crucial role in ensuring normal operation and extending the service life of the equipment. During the manufacturing process, the outer diameter surface of the bearing part needs to be ground using grinding equipment to improve the bearing's machining accuracy.

[0003] In the prior art, grinding equipment includes a machine tool and a grinding head. The machine tool has a grinding station, and the grinding head is set in the grinding station. A rotating shaft is rotatably installed in the grinding station. During grinding, the bearing part is sleeved on the outer peripheral wall of the rotating shaft and clamped and fixed, so that the bearing part and the rotating shaft are integrated. By driving the rotating shaft to rotate at high speed, the grinding head can perform grinding on the outer diameter surface of the bearing part.

[0004] However, when such grinding equipment is used for grinding, the disassembly and assembly of bearing parts and rotating shafts are mostly done manually, resulting in low grinding efficiency and making it unsuitable for grinding large batches of bearings. Therefore, there is an urgent need for a highly automated bearing grinding equipment to improve the grinding efficiency of bearings. Summary of the Invention

[0005] To improve the grinding efficiency of bearings, this application provides an automatic bearing grinding device.

[0006] The automatic bearing grinding equipment provided in this application adopts the following technical solution:

[0007] An automatic bearing grinding device includes a machine tool, a grinding head, a drive module, and a loading module. The machine tool has a grinding station, and the grinding head is disposed within the grinding station. The drive module includes a drive disk and a movable disk. The drive disk is rotatably mounted within the grinding station. A first sliding seat is slidably mounted on the machine tool. The movable disk is rotatably mounted on the first sliding seat and coaxially arranged with the drive disk. The drive disk and the movable disk are spaced apart to form a clamping area. The loading module is disposed on the machine tool for transferring bearing parts to the clamping area.

[0008] By adopting the above technical solution, during the grinding process, the bearing part to be processed is transferred to the clamping area via the loading module. Then, the first sliding seat is driven to slide, forcing the movable disc to slide towards the side closer to the drive disc, so that the drive disc and the movable disc together clamp the two ends of the bearing part. Next, the drive disc is driven to rotate at high speed, and the grinding head can perform grinding operations on the outer diameter surface of the bearing part. After grinding, the movable disc is driven to slide away from the drive disc, and the ground bearing part can fall off under its own gravity. The combination of the drive disc, the movable disc, and the loading module greatly reduces manual intervention, thereby improving the grinding efficiency of bearing parts.

[0009] Optionally, the feeding module includes a feeding rack and a feeding arm. The feeding rack is located on one side of the grinding station. The feeding rack has a feeding channel for storing bearing parts. The end of the feeding rack near the grinding station forms the outlet end of the feeding channel. The bearing parts in the feeding channel slide freely towards the outlet end of the feeding channel. A second sliding seat is slidably installed at the bottom of the feeding rack. One end of the feeding arm is connected to the second sliding seat. The end of the feeding arm away from the second sliding seat has a groove for receiving bearing parts. When the second sliding seat slides to the side near the grinding station, the groove of the feeding arm moves into the clamping area, and the feeding arm covers the outlet end of the feeding channel.

[0010] By adopting the above technical solution, multiple bearing parts to be processed are stored in the feeding channel. Under normal conditions, the bearing parts slide towards the outlet end of the feeding channel under their own gravity, and then fall into the groove of the feeding arm. The second sliding seat is driven to slide closer to the grinding station, and the feeding arm can transfer the bearing parts that have fallen into the groove to the clamping area for grinding. During this process, the feeding arm blocks the outlet end of the feeding channel to prevent the bearing parts from falling out of the feeding channel uncontrollably, thereby achieving the effect of "feeding" one by one.

[0011] Optionally, one end of the feeding arm is hinged to the second sliding seat, and a tension spring is provided between the feeding arm and the second sliding seat. One end of the tension spring is connected to the feeding arm, and the other end is connected to the second sliding seat.

[0012] By employing the above technical solution, the second sliding seat is driven to slide closer to the grinding station, allowing the loading arm to transfer the bearing parts that have fallen into the slot to the clamping area. Then, the bearing parts are clamped by the drive plate and the movable plate. Finally, the second sliding seat is driven to reset. At this point, the loading arm can rotate at a certain angle to avoid the bearing parts. The loading arm is hinged to the second sliding seat, ensuring that the loading arm can smoothly retract.

[0013] Optionally, the first sliding seat is provided with a mounting plate, and the movable plate is rotatably mounted on the surface of the mounting plate. The mounting plate is provided with a centering mechanism for centering the bearing parts.

[0014] By adopting the above technical solution, the bearing parts are quickly centered by the centering mechanism, ensuring that the bearing parts and the drive disk remain coaxial when the drive disk and the movable disk clamp the bearing parts, thereby improving the grinding accuracy of the grinding head on the bearing parts.

[0015] Optionally, the centering mechanism includes a rotating shaft, a centering arc strip, and a rotating component. The rotating shaft is rotatably mounted on the mounting plate and coaxially arranged with the drive plate. One end of the centering arc strip is hinged to the surface of the mounting plate near the clamping area. The outer arc surface of the centering arc strip is used to abut against the inner circumferential wall of the bearing part. Multiple centering arc strips are spaced around the central axis of the rotating shaft. Each centering arc strip is connected to the rotating shaft by a connecting rod. One end of the connecting rod is hinged to the centering arc strip, and the other end is hinged to the rotating shaft. The rotating component is used to drive the rotating shaft to rotate.

[0016] By adopting the above technical solution, when the drive plate and the movable plate clamp the bearing parts, the rotating component drives the rotating shaft to rotate. The rotating shaft pushes the centering arc strips through the connecting rod, forcing the free ends of all the centering arc strips to expand outward. This forces the outer arc surface of the centering arc strips to abut against the inner circumferential wall of the bearing parts, achieving a "centering" effect on the bearing parts. This ensures that when the drive plate and the movable plate clamp the bearing parts, the bearing parts and the drive plate maintain a high degree of coaxiality, thereby improving the grinding quality of the bearing parts.

[0017] Optionally, the rotating component includes a guide rod and a guide block. One end of the rotating shaft is provided with an insertion groove. One end of the guide rod is fixed to the side wall of the machine tool, and the other end is inserted into the insertion groove. The guide block is disposed on the outer peripheral wall of the guide rod. The inner peripheral wall of the insertion groove is provided with a guide groove for the guide block to be embedded. When the mounting plate drives the movable plate to abut against the bearing parts, the guide block drives the rotating shaft to rotate through the guide groove and forces the free ends of all centering arc strips to expand outward.

[0018] By adopting the above technical solution, when the first sliding seat drives the mounting plate to slide towards the side closer to the drive plate, the guide rod is fixedly connected to the machine tool, allowing the guide block to slide within the guide groove. When the mounting plate drives the movable plate to abut against the bearing part, the guide block drives the rotating shaft to rotate through the guide groove and forces the free ends of all centering arc strips to expand outward, so that the outer arc surface of the centering arc strip abuts against the inner circumferential wall of the bearing part, thereby achieving a "centering" effect on the bearing part and improving the coaxiality between the bearing part and the drive plate when the drive plate and the movable plate clamp the bearing part.

[0019] Optionally, the guide groove is formed sequentially into a first point, a second point, a third point, and a fourth point along the axial direction of the rotation shaft. When the guide block is at the first point, the mounting plate slides away from the drive plate to expand the clamping area. When the guide block is at the second point, the centering arc strip moves into the bearing part. When the guide block is at the third point, the free ends of all the centering arc strips expand outward. When the guide block is at the fourth point, the movable plate and the drive plate abut against both ends of the bearing part.

[0020] By adopting the above technical solution, under normal conditions (when the bearing part has not been moved into the clamping area), the mounting plate is driven to slide away from the drive plate, causing the guide block to move to the first position, thereby expanding the clamping area to facilitate the movement of the bearing part into the clamping area. After the bearing part is moved into the clamping area, the mounting plate is driven to slide closer to the drive plate, causing the guide block to move to the second position, thereby forcing the centering arc strip to move into the bearing part. The mounting plate continues to slide closer to the drive plate, causing the guide block to move to the third position. At this point, the guide block forces the rotating shaft to rotate, causing the free ends of all the centering arc strips to expand outward, thus "centering" the bearing part. The mounting plate continues to slide closer to the drive plate, causing the guide block to move to the fourth position. At this point, the movable plate and the drive plate together press against both ends of the bearing part, thereby clamping and fixing the bearing part. The drive plate is then driven to rotate, enabling the bearing part to rotate at high speed for grinding operations, improving grinding quality.

[0021] Optionally, an abutment ring is slidably installed on the surface of the movable disk near the clamping area, and a return spring is provided between the abutment ring and the movable disk. When the guide block is at the fourth position, the abutment ring abuts against the end face of the bearing part, and the return spring contracts and deforms.

[0022] By adopting the above technical solution, when the guide block moves to the fourth position, the movable disk and the drive disk together press against both ends of the bearing part, and the abutment ring squeezes the return spring, forcing the return spring to contract and deform to form elastic force. After the bearing part is ground, the mounting disk drives the movable disk to slide away from the drive disk, causing the guide block to move from the fourth position to the third position, and then from the third position to the second position. During the process of the guide block moving from the third position to the second position, the centering arc strip releases the bearing part, and at this time the return spring releases its elastic force, thereby ejecting the bearing part and improving the separation effect between the bearing part and the mounting disk.

[0023] Optionally, the inner wall of the insertion slot is provided with a rotation clearance groove, which is connected to the fourth point of the guide slide. When the drive disc drives the bearing parts to rotate, the bearing parts force the guide block to move into the rotation clearance groove, and when the guide block moves into the rotation clearance groove, the centering arc strip loosens the inner peripheral wall of the bearing parts.

[0024] By adopting the above technical solution, when the guide block slides to the fourth position, the drive disk and the movable disk together clamp the two ends of the bearing part, and the outer arc surfaces of all the centering arc strips abut against the inner circumferential wall of the bearing part. At this time, the drive disk drives the bearing part to rotate, and the friction between the inner circumferential wall of the bearing part and the outer arc surface of the centering arc strip can push the centering arc strip in the opposite direction, thereby forcing the rotating shaft to rotate at a certain angle, forcing the guide block to move into the rotating clearance groove, thereby causing the outer arc surface of the centering arc strip to loosen from the inner circumferential wall of the bearing part, that is, the centering arc strip separates from the bearing part, reducing the friction when the bearing part rotates.

[0025] Optionally, the outer arc surface of the centering arc bar is fitted with a plurality of rolling balls, the outer peripheral wall of which is used to abut against the inner peripheral wall of the bearing component.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up a drive module and a loading module, during the grinding process, the loading module transfers the bearing part to be processed to the clamping area. Then, the first sliding seat is driven to slide, forcing the movable disc to slide towards the side closer to the drive disc, so that the drive disc and the movable disc together clamp the two ends of the bearing part. Next, the drive disc is driven to rotate at high speed, and the grinding head can perform grinding operations on the outer diameter surface of the bearing part. After grinding is completed, the movable disc is driven to slide away from the drive disc, and the ground bearing part can fall off under its own gravity. The combination of the drive disc, the movable disc, and the loading module greatly reduces manual intervention, thereby improving the grinding efficiency of bearing parts.

[0028] 2. With the centering mechanism, when the drive plate and the movable plate clamp the bearing parts, the rotating component drives the rotating shaft to rotate. The rotating shaft pushes the centering arc strips through the connecting rod, forcing the free ends of all the centering arc strips to expand outward. This forces the outer arc surface of the centering arc strips to abut against the inner circumferential wall of the bearing parts, achieving a "centering" effect on the bearing parts. This ensures that when the drive plate and the movable plate clamp the bearing parts, the bearing parts and the drive plate maintain a high degree of coaxiality, thereby improving the grinding quality of the bearing parts.

[0029] 3. With the setting of the rotary clearance groove, when the guide block slides to the fourth position, the drive disk and the movable disk together clamp the two ends of the bearing part, and the outer arc surfaces of all the centering arc strips abut against the inner circumferential wall of the bearing part. At this time, the drive disk drives the bearing part to rotate, and the friction between the inner circumferential wall of the bearing part and the outer arc surface of the centering arc strip can push the centering arc strip in the opposite direction, thereby forcing the rotating shaft to rotate at a certain angle, forcing the guide block to move into the rotary clearance groove, thereby causing the outer arc surface of the centering arc strip to loosen from the inner circumferential wall of the bearing part, that is, the centering arc strip separates from the bearing part, reducing the friction when the bearing part rotates.

Detailed Implementation

[0041] The following combination Figures 1-10 This application will be described in further detail.

[0042] Example 1: This application discloses an automatic bearing grinding device.

[0043] Reference Figure 1 , Figure 2 An automatic bearing grinding device includes a machine tool 1, a grinding head 2, a drive module 3, and a feeding module 4. The machine tool 1 has a grinding station 11, and the grinding head 2 is installed in the grinding station 11 for grinding the outer diameter surface of the bearing parts.

[0044] Reference Figure 2 , Figure 3 The drive module 3 includes a drive disk 31 and a movable disk 32. The drive disk 31 is located inside the grinding station 11. A drive shaft 15 is rotatably mounted on the inner wall of the machine tool 1. The drive disk 31 is coaxially fixed to one end of the drive shaft 15. The drive disk 31 is rotatably mounted inside the grinding station 11 through the drive shaft 15. The machine tool 1 is equipped with a drive motor (not shown in the figure). The drive motor is fixedly mounted on the side wall of the machine tool 1. The output shaft of the drive motor is coaxially connected to the drive shaft 15.

[0045] A slide rail 16 is fixedly mounted on the machine tool 1. A first sliding seat 12 is slidably mounted on the slide rail 16. A connecting frame 121 is fixedly connected to the first sliding seat 12. A movable disk 32 is rotatably mounted on the side wall of the connecting frame 121. The movable disk 32 and the drive disk 31 are coaxially arranged. The drive disk 31 and the movable disk 32 are spaced apart to form a clamping area 33 for the bearing parts to be moved in. In this embodiment, the drive source for driving the first sliding seat 12 to slide along the length direction of the slide rail 16 is a linear motor (not shown in the figure). In other embodiments, the first sliding seat 12 can be driven by a cylinder so that the first sliding seat 12 (i.e., the movable disk 32) can move closer to or away from the drive disk 31.

[0046] Reference Figure 3 , Figure 4 The loading module 4 is disposed on the machine tool 1 to transfer bearing parts to the clamping area 33. In this embodiment, the loading module 4 includes a loading rack 41 and a loading arm 42. The loading rack 41 is fixedly installed on the inner wall of the machine tool 1 and located on one side of the grinding station 11. The loading rack 41 has a loading channel 411 for storing bearing parts. The end of the loading rack 41 near the grinding station 11 forms the outlet end of the loading channel 411, which is set downward. The height of the loading channel 411 gradually decreases from the end away from the grinding station 11 to the end near the grinding station 11. Under normal conditions, the bearing parts in the loading channel 411 slide freely towards the outlet end of the loading channel 411 under their own gravity.

[0047] A second sliding seat 13 is slidably mounted on the bottom of the loading rack 41. One end of the loading arm 42 is hinged to the side wall of the second sliding seat 13. A groove 421 for receiving bearing parts is provided at the end of the loading arm 42 away from the second sliding seat 13. A tension spring 422 is provided between the loading arm 42 and the second sliding seat 13. One end of the tension spring 422 is fixedly connected to the loading arm 42, and the other end is fixedly connected to the side wall of the second sliding seat 13. The machine tool 1 is equipped with a first cylinder (not shown in the figure). The cylinder body of the first cylinder is fixedly mounted on the second sliding seat 13, and the piston rod of the first cylinder is fixedly connected to the side wall of the second sliding seat 13.

[0048] When the piston rod of the first cylinder retracts inward, the second sliding seat 13 slides to the side away from the grinding station 11, and the groove 421 of the loading arm 42 is directly opposite the outlet end of the loading channel 411; when the piston rod of the first cylinder extends outward, the second sliding seat 13 slides to the side close to the grinding station 11, and the groove 421 of the loading arm 42 moves into the clamping area 33. In addition, when the groove 421 of the loading arm 42 moves into the clamping area 33, the top wall of the loading arm 42 covers the outlet end of the loading channel 411.

[0049] Reference Figure 2 The machine tool 1 is equipped with a collection hopper 17, which is located on the side of the second sliding seat 13 away from the grinding station 11. The machine tool 1 is equipped with a feeding rack 18, which has a feeding channel 181. One end of the feeding channel 181 extends to the bottom of the grinding station 11, and the other end extends to the top of the collection hopper 17. The height of the feeding channel 181 gradually decreases from the end near the grinding station 11 to the end away from the grinding station 11, so that the ground bearing parts can roll down along the feeding channel 181 into the collection hopper 17.

[0050] The implementation principle of Embodiment 1 of this application is as follows: Under normal conditions, the bearing parts slide down towards the outlet end of the feeding channel 411 under their own gravity, and fall into the groove 421 of the feeding arm 42; the second sliding seat 13 is driven to slide closer to the grinding station 11 to transfer the bearing parts that have fallen into the groove 421 to the clamping area 33; then the movable disk 32 is driven closer to the drive disk 31, so that the drive disk 31 and the movable disk 32 respectively abut against the two ends of the bearing parts to clamp and fix the bearing parts; then the feeding arm 42 is driven to retract, and the drive disk 31 is driven to rotate at high speed, so that the grinding head 2 can perform grinding operations on the outer diameter surface of the bearing parts.

[0051] After grinding is completed, the movable disc 32 is driven to slide away from the drive disc 31, and the ground bearing parts can fall into the unloading channel 181 under their own gravity. The combination of drive disc 31, movable disc 32, loading frame 41, loading arm 42 and unloading frame 18 greatly reduces the degree of manual intervention, thereby improving the grinding efficiency of bearing parts.

[0052] Example 2: This application discloses an automatic bearing grinding device.

[0053] The difference between the automatic bearing grinding equipment disclosed in this application and Embodiment 1 is that:

[0054] Reference Figure 5 , Figure 6 The first sliding seat 12 has a connecting frame 121 fixedly mounted with a mounting plate 14. The movable plate 32 is rotatably mounted on the surface of the mounting plate 14 near the driving plate 31. The movable plate 32 is rotatably mounted on the connecting frame 121 via the mounting plate 14. In this embodiment, the movable plate 32 is set in a ring shape, and the mounting plate 14, the driving plate 31 and the rotating plate are coaxially arranged.

[0055] The mounting plate 14 is equipped with a centering mechanism 5, which is used to center the bearing parts to improve the coaxiality between the bearing parts and the drive plate 31. The centering mechanism 5 includes a rotating shaft 51, a centering arc strip 52, and a rotating component. The rotating shaft 51 is rotatably mounted on the mounting plate 14 and coaxially arranged with the drive plate 31. The centering arc strip 52 is arc-shaped, and one end of the centering arc strip 52 is hinged to the surface of the mounting plate 14 near the clamping area 33. For ease of description, the other end of the centering arc strip 52 is defined as the free end of the centering arc strip 52. The outer arc surface of the centering arc strip 52 is used to abut against the inner peripheral wall of the bearing parts. Multiple centering arc strips 52 are spaced around the central axis of the rotating shaft 51. Each centering arc strip 52 is connected to the rotating shaft 51 by a connecting rod 53. One end of the connecting rod 53 is hinged to the centering arc strip 52, and the other end is hinged to the rotating shaft 51.

[0056] The rotating component is used to drive the rotating shaft 51 to rotate. In this embodiment, the rotating component is set as a second cylinder 56. The cylinder body of the second cylinder 56 is hinged to the side wall of the connecting frame 121, and the movable rod of the second cylinder 56 is hinged to the rotating shaft 51. When the piston rod of the second cylinder 56 retracts inward, the rotating shaft 51 drives the free ends of all the centering arc strips 52 to retract inward. When the piston rod of the second cylinder 56 extends outward, the rotating shaft 51 drives the free ends of all the centering arc strips 52 to expand outward, so that the outer arc surface of the centering arc strip 52 abuts against the inner peripheral wall of the bearing part.

[0057] The implementation principle of Embodiment 2 of this application is as follows: After the bearing part is moved into the clamping area 33 by the loading arm 42, the mounting plate 14 is driven to slide towards the side closer to the drive plate 31, so that the centering arc strip 52 moves into the bearing part. Then, the second cylinder 56 forces the free ends of all the centering arc strips 52 to expand outward so that the outer arc surface of the centering arc strip 52 abuts against the inner peripheral wall of the bearing part, thereby "centering" the bearing part.

[0058] After the bearing part is centered, the mounting plate 14 continues to slide towards the side closer to the drive plate 31, so that the drive plate 31 and the movable plate 32 clamp the two ends of the bearing part together. Then, the second cylinder 56 forces the free ends of all the centering arc bars 52 to retract inward, so that the outer arc surface of the centering arc bar 52 is separated from the inner circumferential wall of the bearing part. At this time, the drive plate 31 can drive the bearing part to rotate for grinding. The setting of the centering arc bar 52 improves the coaxiality between the bearing part and the drive plate 31, thereby improving the grinding quality of the bearing part.

[0059] Example 3: This application discloses an automatic bearing grinding device.

[0060] The difference between the automatic bearing grinding equipment disclosed in this application and Embodiment 2 is that:

[0061] Reference Figure 7 , Figure 8 In this embodiment, the rotating component includes a guide rod 54 and a guide block 55. The end of the rotating shaft 51 away from the drive disk 31 is provided with an insertion groove 511. One end of the guide rod 54 is fixed to the side wall of the machine tool 1, and the other end is inserted into the insertion groove 511. The guide block 55 is fixedly installed on the outer peripheral wall of the guide rod 54. The inner peripheral wall of the insertion groove 511 is provided with a guide groove 6 for the guide block 55 to be inserted. When the mounting disk 14 drives the movable disk 32 to abut against the bearing parts, the guide block 55 drives the rotating shaft 51 to rotate through the guide groove 6 and forces the free ends of all the centering arc bars 52 to expand outward.

[0062] Reference Figure 8 , Figure 9 The guide groove 6 includes a first straight segment 66, a connecting segment 67, and a second straight segment 68. Both ends of the first straight segment 66 and the second straight segment 68 extend along the axial direction of the rotation shaft 51. The first straight segment 66 is located on the side of the second straight segment 68 closer to the drive disk 31. The two ends of the connecting segment 67 are connected to the first straight segment 66 and the second straight segment 68, respectively. The end of the first straight segment 66 away from the connecting segment 67 forms a first point 61. The connection between the first straight segment 66 and the connecting segment 67 forms a second point 62. The connection between the connecting segment 67 and the second straight segment 68 forms a third point 63. The end of the second straight segment 68 away from the connecting segment 67 forms a fourth point 64.

[0063] When the mounting plate 14 slides away from the drive plate 31 and forces the guide block 55 to move to the first position 61, the clamping area 33 expands (i.e., the distance between the drive plate 31 and the movable plate 32 is greater than the thickness of the bearing part); when the mounting plate 14 slides closer to the drive plate 31 and forces the guide block 55 to move to the second position 62, the centering arc 52 of the mounting plate 14 moves into the bearing part.

[0064] As the mounting plate 14 continues to slide toward the side closer to the drive plate 31 and forces the guide block 55 to move to the third position 63, the guide block 55 drives the rotating shaft 51 to rotate and the free ends of all the centering arc bars 52 to expand outward; as the mounting plate 14 continues to slide toward the side closer to the drive plate 31 and forces the guide block 55 to move to the fourth position 64, the movable plate 32 and the drive plate 31 together press against both ends of the bearing parts.

[0065] Reference Figure 9 , Figure 10 The inner wall of the insertion slot 511 is provided with a rotation clearance groove 65, which connects to the fourth point 64 of the guide slide 6. When the drive disk 31 drives the bearing component to rotate, the bearing component forces the guide block 55 to move into the rotation clearance groove 65. When the guide block 55 moves into the rotation clearance groove 65, the centering arc strip 52 loosens the inner peripheral wall of the bearing component. It should be noted that in this embodiment, the rotation direction of the rotating shaft 51 forcing the centering arc strip 52 to abut against the bearing component is consistent with the rotation direction of the drive disk 31, so that when the drive disk 31 rotates, the bearing component generates a thrust on the centering arc strip 52, forcing the rotating shaft 51 to rotate in the opposite direction, so that the guide block 55 moves into the rotation clearance groove 65.

[0066] It should be noted that in this embodiment, the cross-sectional shape of the guide block 55 is set to be circular, and the connection between the rotary clearance groove 65 and the second straight segment 68 has a guide surface 69. When the guide block 55 moves into the rotary clearance groove 65 and drives the mounting plate 14 to slide away from the drive plate 31, the guide block 55 moves back into the second straight segment 68 through the guide surface 69.

[0067] Reference Figure 7 , Figure 8 In this embodiment, each centering arc strip 52 has multiple embedding grooves on its outer arc surface, and each embedding groove has a rolling ball 521 rolled in it. The outer peripheral wall of the rolling ball 521 is used to abut against the inner peripheral wall of the bearing part.

[0068] A sliding groove is provided on the surface of the movable disk 32 near the clamping area 33. The sliding groove is annular around the central axis of the movable disk 32. An abutment ring 321 is slidably installed in the sliding groove. A return spring 322 is provided between the abutment ring 321 and the movable disk 32. One end of the return spring 322 is fixedly connected to the inner wall of the sliding groove, and the other end is fixedly connected to the abutment ring 321. Under normal conditions, the return spring 322 forces the abutment ring 321 to be partially exposed outside the sliding groove. When the guide block 55 is located at the fourth point 64, the abutment ring 321 presses against the end face of the bearing part, and the abutment ring 321 moves into the sliding groove and forces the return spring 322 to contract and deform.

[0069] The implementation principle of Embodiment 3 of this application is as follows: Under normal conditions (when the bearing parts are not moved into the clamping area 33), the mounting plate 14 is driven to slide away from the drive plate 31, so that the guide block 55 moves to the first point 61, thereby expanding the clamping area 33 so that the loading arm 42 can move the bearing parts into the clamping area 33.

[0070] After the bearing component is moved into the clamping area 33, the mounting plate 14 is driven to slide towards the side closer to the drive plate 31, causing the guide block 55 to move to the second point 62, thereby forcing the centering arc strip 52 to move into the bearing component.

[0071] Continue to drive the mounting plate 14 to slide towards the side closer to the drive plate 31, so that the guide block 55 moves to the third point 63. At this time, the guide block 55 forces the rotating shaft 51 to rotate through the inner wall of the connecting section 67, causing the free ends of all the centering arc bars 52 to expand outward, so as to "center" the bearing parts.

[0072] Continue to drive the mounting plate 14 to slide towards the side closer to the drive plate 31, so that the guide block 55 moves to the fourth position 64. At this time, the movable plate 32 and the drive plate 31 together press against the two ends of the bearing part, thereby clamping and fixing the bearing part, driving the drive plate 31 to rotate, so that the drive plate 31 can drive the bearing part to rotate at high speed to perform grinding operations and improve grinding quality.

[0073] When the guide block 55 slides to the fourth position 64, the drive disk 31 and the movable disk 32 clamp the two ends of the bearing part together, and the outer arc surfaces of all the centering arc strips 52 abut against the inner circumferential wall of the bearing part. At this time, the drive disk 31 drives the bearing part to rotate. The friction between the inner circumferential wall of the bearing part and the outer arc surface of the centering arc strip 52 can push the centering arc strip 52 in the opposite direction, thereby forcing the rotating shaft 51 to rotate at a certain angle, forcing the guide block 55 to move into the rotating clearance groove 65, thereby loosening the abutment effect of the outer arc surface of the centering arc strip 52 against the inner circumferential wall of the bearing part, that is, separating the centering arc strip 52 from the bearing part, reducing the friction when the bearing part rotates.

[0074] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
