[0021] The lifting and sliding mechanism includes a first electric telescopic rod 8, a lifting slide rail 9, a second slider 10, a lifting frame 11, a drilling rig 12 and a drill bit 13. The first electric telescopic rod 8 is fixedly arranged around the tool change disc 4. The first electric telescopic rod 8 is provided with four groups. The lifting slide rail 9 is symmetrically arranged below the first electric telescopic rod 8. The upper end of the lifting slide rail 9 is fixedly connected to the bottom of the tool change disc 4. The second slider 10 is slidingly arranged on the inner side of the lifting slide rail 9. A lifting frame 11 is fixed between the second sliders 10. A drilling rig 12 is fixedly arranged in the middle below the lifting frame 11. A drill bit 13 is rotatably arranged at the output end of the drilling rig 12. The drill bit 13 adopts different models to facilitate rapid switching according to the drilling requirements. An anti-splash mechanism is arranged below the lifting frame 11. When drilling, the first electric telescopic rod 8 on the drill bit 13 of the corresponding model extends to push the lifting frame 11 and the drilling rig 12 down. At the same time, the drilling rig 12 starts to drive the drill bit 13 to rotate and drill. When the lifting frame 11 descends, it drives the second slider 10 to slide along the lifting slide rail 9 to keep the lifting frame 11 stable.

[0022] The anti-splash mechanism includes a folding cover 14, a support ring 15, a chip removal hole 16 and a collection box 17. The folding cover 14 is fixedly arranged around the lower part of the lifting frame 11, and a support ring 15 is fixedly arranged below the folding cover 14. The chip removal hole 16 is arranged around the workbench 1, and a collection box 17 is arranged below the workbench 1.

The folding cover 14 corresponds to the position of the drilling rig 12. The folding cover 14 is matched to cover the outside of the drilling rig 12. When drilling, the lifting frame 11 descends and drives the folding cover 14 to descend. After the support ring 15 contacts the flange, it drives the folding cover 14 to retract and cover the outside of the drill bit 13 to effectively prevent the debris generated by drilling from splashing, so that the debris can slide into the collection box 17 through the chip removal hole 16 for centralized treatment, thereby solving the problem that the drill bit 13 rotates at a high speed during drilling, which easily drives iron chips to splash everywhere and poses a safety hazard.

The second electric telescopic rod 21 is symmetrically fixedly provided on the lower inner side of the bracket 2, and an arc-shaped clamping plate 22 is matched and fixedly provided above the third slider 20. The telescopic end of the second electric telescopic rod 21 is fixedly connected to the outer side of the arc-shaped clamping plate 22. Before drilling, the flange is placed on the clamping platform 18, and the second electric telescopic rod 21 is extended to push the arc-shaped clamping plate 22 and the third slider 20 to slide along the groove 19 to clamp and fix the two sides of the flange to prevent the flange from being displaced during drilling and affecting the drilling effect.

[0024] When the mechanical parts punching device performs punching processing, the flange to be processed is placed on the clamping table, the second electric telescopic rod is extended to push the arc-shaped clamping plate and the third slider to slide toward each other along the groove, and the first motor drives the tool changing disc to rotate to adjust the tool change. The rotation of the tool changing disc drives the first slider to slide along the annular slide rail to maintain stability. When punching, the first electric telescopic rod corresponding to the drill bit is extended to push the lifting frame to descend along the lifting slide rail. At the same time, the drilling rig is started to drive the drill bit to rotate for drilling. When the lifting frame descends, it drives the folding cover to descend synchronously. When drilling, the folding cover covers the outside of the drill bit to prevent iron chips from splashing, so that the chips slide into the collection box through the chip removal hole. When adjusting the punching position, the first motor drives the tool changing disc to rotate and adjust.
