[0035] The working principle of the positioning device for parts processing provided by the utility model is as follows: when punching a part is required, the part to be processed is first placed on the positioning round block 311 on the workbench 7, and then the servo motor 302 is started to drive the turntable 303 to rotate, the turntable 303 drives the connecting ring 305 to rotate with the help of the belt 304, and the connecting ring 305 drives the boss 307 to move with the help of the connecting hole 306, so that the boss 307 drives the limiting plate 308 to clamp and limit the part on the positioning round block 311, and then the servo motor 302 is started to drive the turntable 303 to rotate, and ... then the servo motor 302 is started to drive the turntable 303 to rotate, and then the servo motor 302 is started to drive the turntable 303 to rotate, and then the servo motor 302 is started to drive the turntable 303 to rotate, and then the servo motor 302 is started to drive the turntable 303 to rotate, and then the servo motor 302 is started to drive the turntable 303 to rotate, and then the servo motor 302 is started to drive the turntable 303 to rotate, and then the servo motor 302 is started to drive the turntable 303 to rotate, and then the servo motor 302 is started to drive the turntable 303 to rotate, and then the serv The hydraulic cylinder 5 drives the punch 6 to punch the part. When the part is processed, the servo motor 302 is started to drive the turntable 303 to rotate in the opposite direction. The turntable 303 drives the connecting ring 305 to rotate in the opposite direction with the help of the belt 304, so that the connecting ring 305 drives several limit plates 308 to separate from the processed parts at the same time. Then the part can be taken off the workbench 7. According to the above steps, the positioning, clamping and punching of the part can be completed. In the process of the boss 307 driving the limit plate 308 to move, the limit plate 308 The positioning rod 309 can guide and position the boss 307, so as to avoid the boss 307 from rotating during its movement, thereby improving the stability of the positioning process of the part. The rubber pad 310 can increase the friction force on one side of the limiting plate 308, thereby improving the limiting effect of the limiting plate 308 on the part. In addition, after the limiting plate 308 clamps the part to be processed, the cylinder 312 can be started to drive the top block 313 to abut against the bottom of the turntable 303, so as to limit the turntable 303, so as to avoid the movement of the limiting plate 308 caused by the personnel starting the servo motor 302 during the part punching process. Finally, by arranging a round block on the upper surface of the workbench 7, the effect of quickly placing the part at the center of the connecting ring 305 is achieved, so that the part to be processed can be quickly placed at the designated position to wait for the next clamping and positioning. By setting the adjustment structure 3, the limiting plate 308 can be automatically driven to clamp and position the parts to be processed of different sizes. The clamping device has a large scope of application and improves the practicality of the processing device.

[0036] When the workbench 7 needs to be moved, the motor 41 is started to drive the gear 44 to rotate, so that the gear 44 moves along the surface of the rack 45. At this time, the motor 41 will drive the fixing ring 42 to move along the arc surface of the connecting rod 43. At the same time, the motor 41 will drive the workbench 7 to move. During the movement of the workbench 7, the positioning plate 46 will move along the arc surface of the positioning rod 47 on the workbench 7, thereby achieving the effect of improving the stability of the movement process of the workbench 7. By setting the auxiliary structure 4, when it is necessary to place the processed parts on the workbench 7, the workbench 7 can be easily moved out from under the punch 6, thereby avoiding the situation where the hands are squeezed by the punch 6, thereby improving the safety of the device.
