[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] Example: A polishing and grinding device for metal parts, such as Figures 1-4 As shown, it includes a grinding mechanism 1, a parts support base 2 is provided on the outside of the grinding mechanism 1, and a parts clamping assembly 3 is provided inside the parts support base 2;
[0025] The spare parts clamping assembly 3 includes a motor 301 installed inside the spare parts support base 2. One end of the motor 301 is connected to a screw 302. A screw cylinder 303 is sleeved on the outside of the screw 302. A conical push block 304 is installed on the outer surface of the screw cylinder 303. A clamping connecting block 305 is slidably arranged on one side of the conical push block 304. A square support block is connected to one side of the clamping connecting block 305. A clamping block 306 is connected to the clamping connecting block 305 through the square support block. A telescopic rod 307 is connected to one side of the directional support block.
[0026] The spare parts clamping assembly 3 includes a motor 301 fixedly connected to the inner wall of one side of the spare parts support base 2. A screw 302 is fixedly connected to the output end of the motor 301. The end of the screw 302 away from the motor 301 is rotatably connected to the inner wall of the spare parts support base 2. Two screw cylinders 303 are screwed into the external threads of the screw 302.
[0027] Two conical push blocks 304 are symmetrically connected to the outer surface of the screw barrel 303. A clamping connecting block 305 is slidably connected to the inclined end of the conical push block 304. One end of the clamping connecting block 305 is inclined, and the inclined end surface of the clamping connecting block 305 is in contact with the inclined end surface of the conical push block 304.
[0028] The horizontal ends of the two clamping connecting blocks 305 are simultaneously fixedly connected to the clamping blocks 306 via the square support blocks. The square support blocks are inserted into the upper end of the parts support base 2. The telescopic end of the telescopic rod 307 is fixedly connected to the square support block, and the other end of the telescopic rod 307 is inserted into the inner wall of the parts support base 2.
[0029] When the metal parts are not clamped, the clamping connecting block 305 is located on the inclined end surface of the cone-shaped pushing block 304 with the largest radius. At this time, the distance between the two clamping blocks 306 is at its maximum. When the metal parts need to be polished, the metal parts are placed between the two clamping blocks 306, and the motor 301 is started, driving the screw 302 to rotate. Based on the threaded connection between the screw barrel 303 and the screw barrel 304, the screw barrel 303 and the clamping connecting block 305 are driven to move along the direction of the screw 302. At this time, under the limit of the telescopic rod 307, the clamping connecting block 305 cannot move back and forth, but can only move along the direction of the telescopic rod 307. When the cone-shaped pushing block 304 moves... As the radius of the contact surface between the clamping connecting block 305 and the conical pushing block 304 gradually decreases, the clamping connecting block 305 is pulled inward, and the clamping block 306 moves inward simultaneously until the two clamping blocks 306 clamp and fix the metal parts. Then, the motor 301 stops running. Then, through the grinding mechanism 1, the robot arm drives the grinding disc to rotate. The front drive device of the robot arm drives the grinding disc to grind and polish the surface of the metal parts. Under the action of the parts clamping assembly 3, metal parts of different specifications can be clamped and ground without replacing the clamping mechanism. While improving the applicability of the grinding device, the grinding efficiency is further improved, ensuring the versatility of the equipment and production efficiency.
[0030] like Figures 1-4 As shown, a support limiting block 308 is fixedly connected to the lower surface of the conical push block 304. The two support limiting blocks 308 located at the long end are simultaneously inserted with support limiting posts 309. The two ends of the support limiting posts 309 are fixedly connected to the inner wall of the component support base 2.
[0031] Under the action of the support limiting block 308 and the support limiting post 309, firstly, they provide support for the conical pushing block 304, avoiding excessive pressure on the telescopic rod 307 caused by the conical pushing block 304 and the clamping connecting block 305, so that the telescopic rod 307 is always in a horizontal state, ensuring the stability of the clamping connecting block 305 during horizontal movement. Secondly, they provide angle limiting for the screw barrel 303 and the conical pushing block 304, further ensuring the stability of the screw barrel 303 and the conical pushing block 304 during movement, and avoiding angle swaying problems of the screw barrel 303 and the conical pushing block 304.
[0032] like Figures 1-4 As shown, the inclined end of the conical push block 304 is provided with a movable limiting groove 310, and the inclined end of the clamping connecting block 305 slides inside the movable limiting groove 310, with the surface of the inclined end of the clamping connecting block 305 in contact with the inner end surface of the movable limiting groove 310.
[0033] The movable limiting groove 310 has sliding grooves 312 on both sides of its inner wall. A slider 311 is slidably arranged inside the sliding groove 312, and the slider 311 is fixedly connected to the clamping connecting block 305.
[0034] When the conical push block 304 pushes and pulls back the clamping connecting block 305, the position of the clamping connecting block 305 within the moving limiting groove 310 on the conical push block 304 changes. Under the limiting action of the sliding groove 312 and the slider 311, the inclined end of the clamping connecting block 305 is always inside the moving limiting groove 310, which avoids the clamping connecting block 305 from disengaging from the conical push block 304 and ensures the stability of the conical push block 304 and the clamping connecting block 305 during operation.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
