An electric slide rail slide 3 is fixed on the slide 2, and a moving frame 5 is provided on the electric slide rail slide 3. A first electric push rod 6 is fixed on the top of both sides of the moving frame 5, and the piston rod of the first electric push rod 6 is fixed with a splint for fixing the mechanical accessories. A cylinder 4 is fixed to the front of the mounting table 1 through an extension frame, and the piston rod of the cylinder 4 is fixed to the sliding frame 2. Fixed slides are provided on both sides of the back of the mounting table 1, and a support frame 7 is slidingly provided in the fixed slide. The bottom of the support frame 7 is fixed with a first spring 10 whose bottom end is fixed on the bottom of the inner cavity of the strip groove 8. A lifting plate 21 with a bottom end fixed on the lifting seat 9 is inserted on each group of support frames 7. The lifting plate 21 has a T-shaped structure as a whole. The longitudinal length of the top of the lifting plate 21 is greater than the longitudinal length of the top of the support frame 7, which is convenient for the user to lift the lifting plate 21. The bottom of the support frame 7 and the lifting seat 9 are both rotatably equipped with pulleys 12. The surfaces of the upper and lower groups of pulleys 12 are connected with grinding belts 13 used in conjunction with mechanical accessories. The front sides of the support frames 7 that are away from each other are fixed with reinforcement support plates 14 used in conjunction with the grinding belts 13. The design of the reinforcement support plates 14 can support the grinding belts 13 to improve the grinding effect of mechanical accessories.

[0021] Reference Figure 1-Figure 3The lifting seats 9 are close to each other on one side with a motor 11 fixed by a bracket and the output shaft of the motor 11 is fixed to the upper pulley 12. A square groove 22 is provided on the lifting plate 21, and a locking block 23 is slidably set in the square groove 22 and one end of the locking block 23 passes through the lifting plate 21 and fits on the support frame 7. The other end of the locking block 23 is fixed with a second spring 24 and one end of the second spring 24 is fixed to the front of the inner cavity of the square groove 22. A plug-in plate 25 is fixed to the front of the locking block 23. The front of the inner cavity of the square groove 22 is provided with a socket for plugging with the plug-in plate 25. By setting the plug-in plate 25 and the socket, the locking block 23 can be plugged and positioned when it moves into the square groove 22, thereby improving the overall stability of the locking block 23. The support frames 7 are close to each other on one side. A first frame 17 is fixed, a fixed cylinder is embedded in the back of the top of the mounting table 1, and a vertical shaft 15 is rotatably installed in the fixed cylinder, and a rotating frame 16 and a second frame 20 are fixed to the top and bottom ends of the vertical shaft 15 respectively, and both ends of the rotating frame 16 are inserted in the first frame 17, and a second electric push rod 18 is fixed to the bottom of the mounting table 1, and the piston rod of the second electric push rod 18 is fixed to a drive seat 19 used in conjunction with the second frame 20. By setting and adjusting the grinding assembly, the grinding belt 13 is used alternately, and the damaged grinding belt 13 can be quickly replaced in the later stage, which effectively avoids the need for long-term shutdown to replace the grinding belt 13, thereby improving the overall working efficiency of the device, and a controller is provided on one side of the front of the mounting table 1.

[0022] In the present utility model, the user turns on the first electric push rod 6 through the controller, and the first electric push rod 6 can drive the splint to move inward and fix the mechanical parts that need to be processed. Then the user turns on the motor 11 through the controller. The motor 11 can drive the grinding belt 13 to transmit with the cooperation of the pulley 12, and the position of the mechanical parts can be adjusted with the cooperation of the cylinder 4 and the electric slide rail slide 3, so that the side of the mechanical parts close to the grinding belt 13 can be fully polished. If the grinding belt 13 is damaged, the user only needs to turn on the second electric push rod 18 through the controller. At this time, the second electric push rod 18 can drive the second frame 20 to swing with the cooperation of the driving seat 19, so that the rotating frame 16 can be driven to rotate with the cooperation of the vertical shaft 15. At this time, with the cooperation of the first frame 17, the positions of the two sets of support frames 7 can be quickly swapped, so that the positions of the two sets of grinding belts 13 can be quickly adjusted. The user then moves the locking block 23 corresponding to the damaged sanding belt 13 to the rear and the new sanding belt 13 to the front. At this time, the sanding belt 13 can continue to sand the mechanical parts. The user then moves the locking block 23 corresponding to the damaged sanding belt 13, thereby driving it to move inward until the locking block 23 completely enters the square groove 22. At this time, the elastic rebound of the first spring 10 can drive the lifting seat 9 to move down quickly, narrowing the distance between the two sets of pulleys 12, so that the damaged sanding belt 13 can be quickly removed, making it convenient for the user to put the new sanding belt 13 on the pulley 12. The user then only needs to pull the lifting plate 21 upwards. When the locking block 23 is completely moved to the support frame 7, under the action of the second spring 24, the locking block 23 can be pushed to move quickly and lock the lifting plate 21, so that the lifting seat 9 can be quickly locked, and then the new sanding belt 13 can be quickly positioned.
