Specifically, when a person uses it, he first fixes one end of the power motor 2 on the inner ring grinding wheel 3 of a size matching the bearing, places the bearing between the two arc clamping plates 14, and rotates the screw rod 9. Under the action of the thread, the two The distance between the arc-shaped clamping plates 14 is getting closer and closer, and finally the bearing is clamped. The motor 10 drives the screw rod 6 to rotate, so that the screw sleeve 7 can drive the clamped bearing to approach the grinding wheel 3, so that the grinding wheel 3 enters the inner cavity of the bearing to grind its inner ring. The debris generated during the grinding operation will fall to the surface of the operating table 1 due to the weight. During the grinding operation, the displacement of the screw sleeve 7 also drives the brush plate 11 to move, and the debris that falls on the operating table 1 is cleaned. Every time the bearing moves, the brush plate 11 will clean the surface of the adjacent operating table 1. Through the structural design, the personnel can grind the inner ring of the bearing while scraping and cleaning the debris left on the operating table 1 by the previous processing, which reduces the subsequent operating steps for the personnel to maintain the device, improves the overall cleanliness of the device, protects the production environment, and brings convenience to the users.
[0025] This program has the following working process:
[0026] When in use, the personnel first fix one end of the power motor 2 to the inner ring grinding wheel 3 of the size that matches the bearing, and place the bearing between the two arc-shaped clamping plates 14. The personnel rotate the screw 9. Under the action of the thread, the distance between the two arc-shaped clamping plates 14 becomes closer and closer, and finally the bearing is clamped. The motor 10 drives the screw 6 to rotate, so that the screw sleeve 7 can drive the clamped bearing to approach the grinding wheel 3, so that the grinding wheel 3 enters the inner cavity of the bearing to grind its inner ring. The debris generated during the grinding operation will fall to the surface of the operating table 1 due to the weight.

[0027] According to the above working process, we can know that:
[0028] Through the structural design, personnel can scrape and clean the debris left on the operating table 1 from previous processing while grinding the inner ring of the bearing, which reduces the personnel's subsequent operation steps for device maintenance, improves the overall cleanliness of the device, protects the production environment, and brings convenience to users.
[0029] Furthermore, the bottom of the brush plate 11 fits with the top of the operating table 1, and a slider 13 is fixedly connected to the outer arc side of the arc-shaped clamping plate 14. A slide groove 12 adapted to the slider 13 is provided on the top of the brush plate 11.

[0032] Furthermore, a displacement block 17 is fixedly connected to the bottom of the bracket 8 away from the mounting groove 4, and a displacement groove 16 matching the displacement block 17 is provided on one side outer wall of the operating table 1. Specifically, by setting the displacement block 17 and the displacement groove 16, the balance of the entire clamping and limiting structure is maintained during the displacement process.
[0033] Furthermore, a through groove 5 is opened on one side of the top of the operating table 1, and a bevel guide plate 18 is fixedly connected to the bottom of the inner cavity of the through groove 5. A limiting shaft 15 is passed between one end of the screw rod 9 and the outer arc side of the adjacent arc-shaped clamping plate 14. Specifically, through the setting of the limiting shaft 15, the screw rod 9 and the corresponding arc-shaped clamping plate 14 will not be stuck.
[0034] To sum up: when in use, the personnel first fix one end of the power motor 2 to the inner ring grinding wheel 3 of the size that matches the bearing, and place the bearing between the two arc-shaped clamping plates 14. The personnel rotate the screw 9. Under the action of the thread, the distance between the two arc-shaped clamping plates 14 becomes closer and closer, and finally the bearing is clamped. The motor 10 drives the screw 6 to rotate, so that the screw sleeve 7 can drive the clamped bearing to approach the grinding wheel 3, so that the grinding wheel 3 enters the inner cavity of the bearing to grind its inner ring. The debris generated during the grinding operation will fall to the surface of the operating table 1 due to the weight. At the same time as the grinding operation, the displacement of the screw sleeve 7 also drives the brush plate 11 to move, and the debris that falls on the operating table 1 is cleaned. Every time the bearing moves, the brush plate 11 will clean the surface of the adjacent operating table 1. The setting of the slider 13 and the slide groove 12 ensures that the corresponding arc-shaped clamping plate 14 will not rotate when the screw 9 rotates. The setting of the mounting groove 4 reduces the occupation of the external space by the screw rod 6 structure. The screw rod 6 cooperates with the screw sleeve 7 to drive the entire clamping structure to move. The setting of the displacement block 17 and the displacement groove 16 maintains the balance of the entire clamping limit structure during the displacement process. The setting of the limit rotating shaft 15 prevents the screw rod 9 and the corresponding arc-shaped clamping plate 14 from being locked to each other. The structural design allows personnel to scrape and clean the debris left on the operating table 1 from the previous processing while grinding the inner ring of the bearing, reducing the subsequent operating steps for personnel to maintain the device, improving the overall cleanliness of the device, protecting the production environment, and bringing convenience to users.
