In addition, springs and guide blocks are provided inside the pressing and fixing components, which can facilitate rapid resetting and move with them during the pressing and fixing process, so as to facilitate auxiliary processing, have good fixability, and be highly convenient.

[0004] In the process of using this device, it was found that this technology has the following problems: since the positions of the pressing piece and the supporting assembly of the device are relatively fixed, the pressing piece cannot pressurize different parts of the workpiece clamped on the supporting assembly. Therefore, it is necessary to optimize the design of this product and to propose an automotive parts press with high processing accuracy. Utility Model Content

A press machine for automobile parts with high processing accuracy, comprising a processing table 1, wherein both sides of the bottom of the processing table 1 are fixedly connected with a broad floor 2 through connecting plates, a slider 4 is slidably installed in the middle of the top of the processing table 1, a slide groove adapted to the slider 4 is provided in the middle of the top of the processing table 1, the slider 4 is slidably installed in the slide groove, a screw rod 6 is threadedly connected to the slider 4, and the rotation power of the screw rod 6 comes from a No. 1 motor at its end, a pressure platform 5 is fixedly installed on the top of the slider 4, a rotating gear 20 is rotatably installed on the middle of the top of the pressure platform 5 through a bearing, a clamping table 7 is fixedly installed on the top of the rotating gear 20, and the inner part of the clamping table 7 is provided with a screw rod 6. A passive toothed disc 8 is rotatably installed through a bearing in the middle of the bottom of the cavity, a driving gear 9 is meshed on the outer side of the passive toothed disc 8, and the rotational power source of the driving gear 9 is the No. 2 motor at the bottom of the inner cavity of the clamping platform 7, and a guide sleeve 10 is fixedly installed around the passive toothed disc 8. A movable rod 11 is plugged and installed on the guide sleeve 10, and a convex rod 12 is fixedly installed on the inner end top of the movable rod 11. An arc groove 13 adapted to the convex rod 12 is opened on the passive toothed disc 8, and the convex rod 12 is slidably installed in the arc groove 13, and a clamping plate 14 sliding on the top of the clamping platform 7 is fixedly installed on the outer end top of the movable rod 11.

[0022] By setting the clamping table 7, when the workpiece needs to be processed, the workpiece is first placed on the top of the clamping table 7, and then the No. 2 motor is started to drive the active gear 9 to rotate. The rotation of the active gear 9 will drive the passive gear plate 8 to rotate together. At this time, since the guide sleeve 10 guides and limits the movable rod 11, when the passive gear plate 8 rotates, the arc groove 13 squeezes and drives the convex rod 12 to pull the movable rod 11 to move inward. At this time, the clamping plates 14 on the top of the outer ends of the four movable rods 11 will move toward the workpiece, thereby clamping and fixing the workpiece quickly and stably. .

[0023] Reference Figure 1 , 2 3. A fixed plate 15 is fixedly installed on the top rear side of the processing table 1, and side plates 16 are fixedly installed on both sides of the bottom of the top plate of the fixed plate 15. A cylinder 17 is slidably installed in the middle of the side plate 16. A guide plate 18 is fixedly connected to the top of the cylinder 17, and a pressure block 19 facing the center of the clamping table 7 is fixedly installed in the middle of the bottom of the cylinder 17. A track plate 21 is fixedly installed on the top rear side of the pressure platform 5. A rack 22 meshing with the rotating gear 20 is slidably installed on the side of the track plate 21 facing the rotating gear 20. A movable groove meshing with the rack 22 is opened on the track plate 21, and a screw rod 23 is threadedly connected to the rack 22. The rotation power of the screw rod 23 comes from the No. 3 motor at its end.

[0024] Through the above design, when the workpiece is fixed on the clamping table 7, starting the guide plate 18 to extend can drive the pressure block 19 at the bottom of the cylinder 17 to move directly downward to apply pressure on the workpiece. When pressure needs to be applied to other positions on the upper surface of the workpiece, first start the No. 3 motor to drive the screw rod 23 to rotate. At this time, the screw rod 23 will force the rack 22 to move, thereby driving the rotating gear 20 and the clamping table 7 on the top of the rotating gear 20 to rotate together, until the part of the workpiece that needs to be pressurized is rotated to a position perpendicular to the horizontal edge of the pressure platform 5, and then start the No. 1 motor to drive the screw rod 1 6 to rotate, so that the slider 4 drives the pressure platform 5 to move, until the part of the workpiece that needs to be pressurized moves to directly below the pressure block 19. At this time, the guide plate 18 can be started, and the workpiece is pressurized again through the pressure block 19. This design can realize pressurization processing at multiple positions on the top of the workpiece.

[0025] The implementation principle of the embodiment of the present application is:

[0026] First, by setting up the clamping table 7, when the workpiece needs to be processed, the workpiece is first placed on the top of the clamping table 7, and then the No. 2 motor is started to drive the active gear 9 to rotate. The rotation of the active gear 9 will drive the passive gear disc 8 to rotate together. At this time, since the guide sleeve 10 guides and limits the movable rod 11, when the passive gear disc 8 rotates, the arc groove 13 will squeeze and drive the convex rod 12 to pull the movable rod 11 to move inward. At this time, the clamping plate 14 on the top of the outer end of the four movable rods 11 will move toward the workpiece, thereby quickly and stably clamping and fixing the workpiece.

[0027] When the workpiece is fixed on the clamping table 7, the guide plate 18 is started to extend, which can drive the pressure block 19 at the bottom of the cylinder 17 to move directly downward to apply pressure on the workpiece. When pressure needs to be applied to other positions on the upper surface of the workpiece, the No. 3 motor is started first to drive the screw rod 23 to rotate. At this time, the screw rod 23 will force the rack 22 to move, thereby driving the rotating gear 20 and the clamping table 7 on the top of the rotating gear 20 to rotate together, until the part of the workpiece that needs to be pressurized is rotated to a position perpendicular to the horizontal edge of the pressure platform 5, and then the No. 1 motor is started to drive the screw rod 1 6 to rotate, so that the slider 4 drives the pressure platform 5 to move, until the part of the workpiece that needs to be pressurized moves to directly below the pressure block 19. At this time, the guide plate 18 can be started, and the workpiece is pressurized again through the pressure block 19. This design can realize pressurization processing at multiple positions on the top of the workpiece.
