For example, patent application number CN202010948705.1 describes a motor rotor polishing device, which includes a frame, a clamping structure, a polishing structure, and a collecting structure. A rectangular dust guide frame is installed through the middle of the top surface of the frame, and support legs are vertically and symmetrically installed on both sides of the bottom surface of the frame. A support arm is vertically and symmetrically welded on one side of the top surface of the frame, and a clamping structure is installed on the top of the support arm. A polishing structure is vertically installed on the other side of the top surface of the frame, and a collecting structure is connected to the bottom end of the dust guide frame directly below the bottom surface of the frame. This invention can automatically clamp and grind the motor rotor core, thus avoiding the problems of low grinding efficiency, difficulty in controlling accuracy, and high cost caused by manual operation.

In the above technical solution, when grinding the rotor surface, the rotor will have an inclined surface. Currently, the angle of the grinding disc cannot be adjusted to tilt, and the rotor surface can only be ground vertically, which affects the grinding efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 As shown, a rotor inclined plane angle adjustment and grinding device includes a processing table 1. A positioning groove 3 is formed on the upper surface of the processing table 1. A support plate 8 is fixedly installed on one side surface of the processing table 1. A guide rod 9 is fixedly installed on the upper surface of the support plate 8. A top plate 11 is fixedly installed on the upper end of the guide rod 9. A first hydraulic cylinder 12 is fixedly installed on the upper surface of the top plate 11. A movable disk 13 is rotatably mounted on the output end of the first hydraulic cylinder 12. An adjustment component 10 is provided on the guide rod 9 and connected to the movable disk 13. A guide groove 17 is formed on the lower surface of the movable disk 13. 7. A guide block 22 is slidably installed inside. A second hydraulic cylinder 14 is fixedly installed on one side surface of the movable disk 13. The output end of the second hydraulic cylinder 14 is located on the surface of the guide block 22. A mounting bracket 18 is fixedly installed on the lower surface of the guide block 22. A third servo motor 19 is fixedly installed on one side surface of the mounting bracket 18. A rotating shaft 20 is installed on the output end of the third servo motor 19. A connecting plate 21 is fixedly installed on the circumference of the rotating shaft 20. A second servo motor 15 is fixedly installed on the top of the connecting plate 21. A grinding disc 16 is installed on the output end of the second servo motor 15.

[0021] like Figure 1 As shown, several support rods 2 are fixedly installed at equal intervals on the lower surface of the processing table 1, which can support the device.

[0022] like Figure 1 As shown, two clamping plates 7 are slidably installed on the inner surface of the positioning groove 3. A first servo motor 4 is fixedly installed on one side surface of the processing table 1. A bidirectional lead screw 5 is installed at the output end of the first servo motor 4. Two lead screw sleeves 6 are sleeved in the middle of the bidirectional lead screw 5. The two lead screw sleeves 6 are respectively connected to the two clamping plates 7. The bidirectional lead screw 5 is driven to rotate by the output end of the first servo motor 4, so that the two lead screw sleeves 6 move towards each other in the middle of the bidirectional lead screw 5, and at the same time drive the two clamping plates 7 to move towards each other, thereby fixing the rotor.

[0023] like Figure 2 , 3As shown in Figures 4 and 5, the adjustment assembly 10 includes a sliding plate 1001, a plurality of gear teeth 1005, and a sliding groove 1006. The sliding plate 1001 is slidably mounted on the middle of the guide rod 9. The plurality of gear teeth 1005 are disposed on the circumferential surface of the moving disk 13. The sliding groove 1006 is formed on the circumferential surface of the moving disk 13, and a slider 1007 is slidably mounted inside the sliding groove 1006. The top of the sliding plate 1001 is disposed on the surface of the slider 1007. A limit frame 1002 is fixedly mounted on the upper surface of the sliding plate 1001, and a fourth servo motor 1003 is fixedly mounted on the lower surface of the limit frame 1002. A gear 1004 is mounted on the output end of the fourth servo motor 1003. The gear 1004 meshes with the plurality of gear teeth 1005 and drives the moving disk 13 downward through the output end of the first hydraulic cylinder 12. The grinding disc 16 is moved downwards, and the rotating shaft 20 is driven to rotate by the output of the third servo motor 19. This causes the connecting plate 21 to swing, adjusting the tilt angle of the grinding disc 16 to match the angle of the rotor's inclined surface. The second hydraulic cylinder 14 extends and retracts, driving the guide block 22 to move inside the guide groove 17, causing the grinding disc 16 to move forward and fit against the rotor's inclined surface for grinding. At this time, the gear 1004 is driven to rotate by the output of the fourth servo motor 1003, causing the gear 1004 to drive several gear teeth 1005, which in turn causes the moving disc 13 to rotate. This allows the grinding disc 16 to move around the rotor, grinding the rotor once, thus improving the grinding efficiency of the device.

[0024] Working principle of this rotor inclined plane angle adjusting grinding device:

[0025] When using this device to grind the rotor, first, place the rotor between the two clamping plates 7 on the inner surface of the positioning groove 3. Then, the output of the first servo motor 4 drives the bidirectional lead screw 5 to rotate, causing the two lead screw sleeves 6 to move towards each other in the middle of the bidirectional lead screw 5. Simultaneously, this moves the two clamping plates 7 towards each other, fixing the rotor in place. Next, the output of the first hydraulic cylinder 12 drives the moving disc 13 downwards, and the grinding disc 16 downwards. Finally, the output of the third servo motor 19 drives the rotating shaft 20 to rotate, which in turn causes the connecting plate 21 to swing. By moving the grinding disc 16, the tilt angle can be adjusted to match the angle of the rotor's inclined surface. The output end of the second hydraulic cylinder 14 extends and retracts, driving the guide block 22 to move inside the guide groove 17, causing the grinding disc 16 to move forward and fit against the rotor's inclined surface for grinding. At this time, the output end of the fourth servo motor 1003 drives the gear 1004 to rotate, causing the gear 1004 to drive several gear teeth 1005, which in turn causes the moving disc 13 to rotate. This allows the grinding disc 16 to move around the rotor, performing grinding work around the rotor's circumference, thus improving the grinding efficiency of this device.

[0026] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here.
