[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, the utility model provides a hole-punching device for processing cast iron parts, including a support frame 1, a fixed rod 19 is provided on the rear side of the support frame 1, and a certain safe processing distance is maintained to prevent the iron filings generated during drilling from wearing the hole-punching head 10. The top of the fixed rod 19 is fixedly connected to a drill bit frame 20, and the front end of the drill bit frame 20 is fixedly connected to a hydraulic rod 21. The hydraulic rod 21 is used to push a push plate 22 to slide repeatedly. The interior of the push plate 22 is set to a convex shape, and a retaining ring 9 is provided for sliding inside the push plate 22. The retaining ring 9 is set to an inner concave shape. The connection is achieved through the convex shape inside the push plate 22 and the concave shape of the retaining ring 9, so that the retaining ring 9 can be moved. The bottom end of the retaining ring 9 is rotatably connected to the hole-punching head 10, and the top of the hole-punching head 10 is welded and fixed with a connecting block 23. The outer side of the hole-punching head 10 is rotatably provided with a workpiece body 17.

[0024] Specifically, the top of the support frame 1 is fixedly connected to the frame 3, the left side of the frame 3 is fixedly connected to the first motor 2, the output end of the first motor 2 is rotatably connected to the screw 4, and when the screw 4 rotates, the outer sliding block 5 is driven to slide left and right, and the outer side of the sliding block 5 is welded and fixed with a movable plate 6.

[0025] Furthermore, a sliding groove is provided on the outer side of the movable plate 6, and a support seat 7 is provided inside the sliding groove of the movable plate 6 for sliding up and down, so as to facilitate adjustment of the position during drilling. A second motor 8 is fixedly connected to the inside of the support seat 7, and the output end of the second motor 8 is fixedly connected to the sleeve 24. A sliding groove is provided inside the sleeve 24, and the connecting block 23 slides up and down inside the sliding groove of the sleeve 24. The bottom end of the connecting block 23 is integrated with the retaining ring 9.

[0026] Furthermore, the top of the support frame 1 is fixedly connected to the base plate 11, the top side of the base plate 11 is fixedly connected to the rotating seat 12, the outer side of the rotating seat 12 is rotatably connected to the rotating disk 13, and the rotating disk 13 drives the workpiece body 17 to rotate, so as to facilitate drilling of other positions of the workpiece body 17.

[0027] It is worth noting that the top of the rotating disk 13 is fixedly connected to the base 14, and the inside of the base 14 is spirally connected to the threaded rod 15. The threaded rod 15 rotates inside the base 14, and the rear side of the threaded rod 15 is fixedly connected to the clamping disk 16. The threaded rod 15 drives the clamping disk 16 to be tightened against the outside of the workpiece body 17.

[0028] It is worth noting that a collecting box 18 is fixedly connected to the top of the bottom plate 11 , and a feeding trough is provided inside the top of the collecting box 18 . The collecting box 18 is used to collect iron filings generated by the workpiece body 17 .

[0029] It is worth mentioning that the push plate 22 slides back and forth inside the support frame 1. When the drill bit needs to be replaced, the push plate 22 drives the drill bit of a different model to be replaced to the bottom end of the support frame 1. When the drilling head 10 does not need to be replaced, it retreats to the rear side of the support frame 1 to prevent iron filings from wearing the remaining unused drilling heads 10 during the drilling process.

[0030] Among them, the first motor 2 and the second motor 8 are prior art and will not be described in detail. At the same time, the present invention also includes a power supply, a controller and a switch, which are not the main technical points of the present patent and will not be described in detail. The "front, back, left and right" perspectives of the present device are as follows: Figure 1 The direction shown in the figure is the reference.

[0031] Working principle:

[0032] First, the staff places the workpiece body 17 on the top of the rotating disk 13, and rotates the threaded rod 15 inside the base 14 at the top of the disk 13 clockwise. The threaded rod 15 passes through the inside of the base 14 and the tightening plate 16 on the rear side of the threaded rod 15 is pressed against the workpiece body 17. After the installation of the workpiece body 17 is completed, the first motor 2 is started. The first motor 2 drives the screw 4 inside the frame 3 to rotate, and the screw 4 drives the sliding block 5 on the outside to slide. The sliding block 5 drives the moving plate 6 to move, and in the process of moving, the support seat 7 slides up and down in the front end slot of the moving plate 6, and the retaining ring 9 at the bottom end of the second motor 8 inside the support seat 7 is tightened. Slide toward the position of the workpiece body 17 where a hole needs to be drilled. During the sliding process, the piercing head 10 on the outside of the clamping ring 9 drills the workpiece body 17. When drilling a relatively fragile position of the workpiece body 17, the drill bit holder 20 at the top of the fixing rod 19 pushes the hydraulic rod 21 to drive the push plate 22 to move toward the position of the clamping ring 9. During the movement, the protruding position inside the push plate 22 lifts the clamping ring 9 and moves the piercing head 10 at the bottom end of the clamping ring 9 out, and inserts the connecting block 23 at the top end of the clamping ring 9 into the inside of the sleeve 24. After the assembly is completed, the hydraulic rod 21 pulls the push plate 22 back to retract, driving the push plate 22 to return to its original position.

[0033] During the drilling process, the generated iron filings flow into the interior of the collecting box 18 .
