DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides the following technical solutions:

[0031] Embodiment 1: Figure 1-Figure 5 The technical solution shown is a punching machine for processing osteotomy plates, which discloses: a base 1, and a support leg 2 is fixedly installed at the lower end of the base 1, a support frame 3 is fixedly installed at the upper end of the base 1, and the support frame 3 is an inverted "L" shape structure when viewed from the side, an electric telescopic rod 4 is fixedly installed on the inner side of the support frame 3, and a punching device 5 is fixedly installed at the output end of the electric telescopic rod 4;

[0032] It also includes: a fence 6 is fixedly installed on the upper end of the base 1, and the fence 6 is a side "U" shape structure when viewed from above, a servo motor 7 is fixedly installed on the outside of the fence 6, and a different direction threaded rod 8 is fixedly installed on the output end of the servo motor 7, a threaded connector 9 is connected to the outside of the different direction threaded rod 8, a clamping frame 10 is fixedly installed on the outside of the threaded connector 9, and the clamping frame 10 is symmetrically arranged in two groups about the midpoint of the base 1; the threaded connector 9 is threadedly connected to the different direction threaded rod 8 through a threaded hole opened on the inside, and the threaded connector 9 is symmetrically arranged in two groups about the midpoint of the different direction threaded rod 8; a guide block 11 is fixedly installed on the outside of the threaded connector 9, and the guide block 11 is nested in the inside of the guide groove 12, and the guide groove 12 is fixedly installed on the inside of the fence 6;

[0033] When it is necessary to punch a hole in the osteotomy plate of this structure, the osteotomy plate is first placed at a height flush with the clamping frame 10, and then the servo motor 7 is operated. The output end of the servo motor 7 drives the counter-rotating threaded rod 8 to rotate, so that the threaded connectors 9 threadedly connected at both ends of the counter-rotating threaded rod 8 move toward each other. The two sets of threaded connectors 9 move toward each other, so that the two sets of clamping frames 10 connected on the outside are brought together, and the two sides of the osteotomy plate are clamped and fixed to the upper end of the base 1. When the threaded connectors 9 move toward each other, the guide block 11 is driven to slide along the inner side of the guide groove 12. The sliding of the guide block 11 on the inner side of the guide groove 12 limits the angle of the threaded connector 9. When the osteotomy plate is fixed, the electric telescopic rod 4 is operated, and the output end of the electric telescopic rod 4 drives the punching device 5 to move downward, thereby punching the fixed osteotomy plate.

[0034] Embodiment 2 is different from Embodiment 1 in that, in addition to clamping and fixing the osteotomy plate, a structure for cleaning the waste generated by drilling is added, such as Figure 1-Figure 2 , Figure 7 The figure discloses: an axle seat 17 is fixedly installed inside the clamping frame 10, and an adjusting rod 18 is rotatably connected to the outside of the axle seat 17, and two groups of adjusting rods 18 are symmetrically arranged about the midpoint of the concentric shaft 19, and the tail end of the adjusting rod 18 and the concentric shaft 19 form a rotating structure, the concentric shaft 19 is fixedly installed on the outside of the push plate 20, and the push plate 20 and the base 1 are distributed in a corresponding manner up and down; a telescopic spring 21 is connected between the adjusting rods 18;

[0035] In this structure, when the osteotomy plate is punched, the servo motor 7 is operated in the reverse direction, so that the counter-rotating threaded rod 8 rotates in the reverse direction. The counter-rotating threaded rod 8 causes the threaded connector 9 connected with the outer thread to drive the clamping frames 10 on both sides to move backwards. The backward movement of the clamping frames 10 pulls the adjusting rod 18 to rotate through the shaft seat 17 at the bottom, so that the push plate 20 moves toward the front end of the base 1 through the angle adjustment of the adjusting rod 18, and the waste chips scattered on the upper end of the base 1 are pushed into the first chip discharge opening 13.

[0036] Embodiment 3 is different from Embodiment 2 in that, in addition to cleaning the waste generated by punching, a structure for facilitating removal is added, such as Figure 1-Figure 2 , Figure 6 The figure discloses: a first chip discharge opening 13 and a second chip discharge opening 14 are opened on the inner side of the base 1; the inner side of the base 1 is a hollow structure, and an ash storage box 15 is slidably connected to the inner side of the base 1, and a pull ring 16 is fixedly installed on the outer side of the ash storage box 15;

[0037] In this structure, waste chips enter the ash storage box 15 through the first chip discharge port 13 and the second chip discharge port 14. When the waste chips in the ash storage box 15 need to be processed, the pull ring 16 can be manually pulled to slide the ash storage box 15 outward along the inner side of the base 1, so that the ash storage box 15 can be taken out to facilitate cleaning of the waste chips inside.
