[0037] like Figure 1 As shown, as a preferred embodiment, on the basis of the above method, the lifting assembly 3 further includes a pneumatic cylinder 301 installed at the center of the L-shaped bracket 2, and a telescopic rod 302 is provided at the telescopic end of the pneumatic cylinder 301, and a slide 303 is fixedly installed at the end of the telescopic rod 302 away from the pneumatic cylinder 301, and a symmetrically distributed first slider 304 is fixedly provided at the end of the slider 303 close to the L-shaped bracket 2, and a symmetrically distributed first slide groove 7 is opened on the inner side wall of the L-shaped bracket 2, and the inner side wall of the first slide groove 7 is slidably connected to the first slider 304, and the telescopic rod 302 is driven to extend downward by the provided pneumatic cylinder 301. When the telescopic rod 302 extends downward, the slide 303 fixedly installed at the bottom end of the telescopic rod 302 is driven to slide downward along the inner wall of the first slide groove 7.

[0038] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, a driving shaft 8 is fixedly installed at the bottom of the skateboard 303, a drill bit 9 is fixedly provided at the output end of the driving shaft 8, the driving shaft 8 is arranged between the two sets of limit assemblies 6, and a protective cover 18 is fixedly installed at the bottom of the skateboard 303 covering the outside of the driving end of the driving shaft 8. By installing the driving shaft 8 at the bottom of the skateboard 303, the drill bit 9 is driven to rotate, thereby facilitating drilling of the tool.

[0039] like Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, a base 1 is fixedly installed on the outer side wall of the bottom of the L-shaped bracket 2, and a second slide groove 10 is provided on the side walls at both ends of the base 1. The inner wall of the second slide groove 10 is slidably connected with a symmetrically distributed second slider 11, and one end of any group of second sliders 11 is fixedly installed with a frame-shaped clamp 12, and a fixing screw 13 is threadedly connected at the top center of the frame-shaped clamp 12. The tool is clamped and fixed by the set frame-shaped clamp 12 and the fixing screw 13, which is convenient for subsequent drilling of the tool.

[0040] like Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, a hollow plate 14 is fixedly installed in the middle of the base 1, a collecting box 15 is provided below the hollow plate 14, a handle 16 is fixedly installed on the outer wall of the collecting box 15, and support blocks 17 are fixedly provided at the four corners of the bottom of the base 1. Through the hollow plate 14, the debris generated during the drilling process is conveniently collected into the collecting box 15, so that the debris can be centrally processed.

[0041] Specifically, when the present drilling device for carbide tool processing is used: first, the tool is clamped and fixed by the provided frame-shaped fixture 12 and fixing screws 13, so as to facilitate the subsequent drilling of the tool;

[0042] The screw rod 501 is driven to rotate by a rotating handle 502, and the threads at both ends of the screw rod 501 are opposite. When the rotating handle 502 drives the screw rod 501 to rotate forward, the slides 503 at both ends of the screw rod 501 approach each other. When the rotating handle 502 drives the screw rod 501 to rotate reversely, the slides 503 at both ends of the screw rod 501 move away from each other. A contact switch 506 is also installed at the bottom of the slide 503, so that the two sets of contact switches 506 can be adjusted to the desired position according to the required depth of the drilling.

[0043] Then, the pneumatic cylinder 301 is provided to drive the telescopic rod 302 to extend downward. When the telescopic rod 302 extends downward, it simultaneously drives the slide 303 fixedly installed at the bottom end of the telescopic rod 302 to slide downward along the inner wall of the first slide groove 7. In addition, symmetrically distributed support rods 603 are provided at the bottom of the slide 303. When the slide 303 slides downward, the rollers 604 installed on the inner side walls of the bottom of the support rods 603 press against the surface of the tool, thereby preventing the vibration generated during the drilling process from causing the tool to deviate, resulting in low drilling accuracy.

[0044] A driving shaft 8 is installed at the bottom of the slide 303 to drive the drill bit 9 to rotate. The contact switch 506 is electrically connected to the pneumatic cylinder 301 and the driving end of the driving shaft 8. When the push rod 603 tilts to a certain angle during the downward pressing process, the side wall of the push rod 603 touches the contact switch 506. At this time, the pneumatic cylinder 301 and the driving end of the driving shaft 8 stop working, thereby preventing the base from being damaged by drilling too deep during the drilling process and facilitating the adjustment of the drilling depth.

[0045] Finally, the hollow plate 14 is provided to facilitate the collection of debris generated during the drilling process into the collection box 15, so that the debris can be centrally processed.

[0046] All technical features in this embodiment can be freely combined according to actual needs.

[0047] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
