The slide 15 will drive the block 17 to move together during the sliding process. After moving a certain distance, the two sets of blocks 17 will be inserted into the slots 20 at both ends of the piston rod body 3, thereby fixing the piston rod body 3. After fixing, start the motor again 10, the polishing disc 11 is driven to rotate by the motor 10, and the electric telescopic rod 8 is started after the polishing disc 11 rotates, and the rotating polishing disc 11 is driven to move downward by the electric telescopic rod 8, and the polishing disc 11 will grind the piston rod body 3 after moving a certain distance. When the polishing disc 11 needs to be moved left and right, the motor 2 12 can be started, and the threaded rod 13 is driven to rotate by the motor 2 12. The threaded rod 13 will drive the slider 7 to slide inside the slide groove 6 during the rotation process, and the slider 7 will drive the polishing disc 11 to move together during the sliding process. When the processing surface of the piston rod body 3 needs to be adjusted, the two groups of motors 3 16 can be started at the same time, and the clamping block 17 can be driven to rotate by the motor 3 16. The clamping block 17 will drive the piston rod body 3 to rotate together during the rotation process, and the motor 3 16 can be turned off after rotating a certain angle. When processing the piston rod body 3, debris is inevitably generated, which can be collected by the collection box 22. When there are a lot of debris in the collection box 22, the handle 23 can be pulled to drive the collection box 22 to slide inside the slot 21. After sliding a certain distance, it can be taken out and dumped.
