[0040] After the thick steel plate is placed, the movable frame 501 moves downward under the drive of the frame body 3, so that the rotating shaft 503 drives the cone rod 510 to rotate, and the drilling assembly 507 moves downward to drill holes in the thick steel plate and gradually expand the hole diameter. When drilling, the mounting plate 509 drives the support rod 504 to rotate, so that the pad 506 contacts the top of the thick steel plate, and the telescopic column 502 gradually moves downward to squeeze the support rod 504, making the thick steel plate more stable. Then the protective assembly 508 is close to the drilling position to avoid splashing of debris generated by drilling, and after drilling is completed, the debris is pushed into the drilled hole, so that the debris falls into the collection box 4.

The outer wall of the frame rod 1032 is evenly provided with soft blocks 1034, and the outer wall of the soft blocks 1034 is fixedly connected to the outer wall of the frame rod 1032. The outer wall of the soft blocks 1034 is provided with air holes 1035, and the soft blocks 1034 have large elasticity and friction.

[0043] After the thick steel plate is placed on the machine 101, the hydraulic rod 1031 drives the frame rod 1032 to extend, so that the soft block 1034 contacts and absorbs the bottom of the thick steel plate, thereby driving the thick steel plate to move inward. After reaching the appropriate position, the hydraulic rod 1031 drives the frame rod 1032 to extend, so that the frame rod 1032 supports the thick steel plate. According to the position of the punching hole, the hydraulic rod 1031 at the corresponding position drives the frame rod 1032 to retract into the machine 101 to leave space for punching holes.

The end of the first telescopic rod 5072 close to the rotating shaft 503 is connected to the drill bit 5071. 071 is fixedly connected, one end of the first telescopic rod 5072 away from the rotating shaft 503 is fixedly connected with a U-shaped block 5073, the U-shaped block 5073 is made of metal rigid material, the shape of the U-shaped block 5073 is fan-shaped, and its arc surface fits with the outer wall of the drill bit 5071, the outer wall of the U-shaped block 5073 is sleeved with the inner wall of the drill bit 5071, the outer wall of the U-shaped block 5073 is provided with a frosted surface 5074, and the bottom of the U-shaped block 5073 is fixedly connected with a cleaning block 5075.

[0045] When drilling, the tapered rod 510 is inserted into the thick steel plate, and then the bottom drill bit 5071 drills a hole in the thick steel plate, and then the rotating shaft 503 continues to move downward, so that the second drill bit 5071 drills a hole in the thick steel plate. The diameter of the top drill bit 5071 is the same as the predetermined drilling diameter. When the drill bit 5071 drills into the thick steel plate, the first telescopic rod 5072 extends, and the telescopic column 502 controls the height, so that the U-shaped block 5073 in the drill bit 5071 contacts the top of the thick steel plate at this time, so that the cleaning block 5075 cleans the dust around the drilling hole, and the dust is cleaned into the collection box 4 by the protective component 508.

[0047] When the pad 506 contacts the top of the thick steel plate, the cover shells 5081 on both sides surround the drilling position to prevent debris from splashing to the sides of the machine 101. When debris is generated during drilling, the second telescopic rod 5082 contracts, driving the elastic rod 5085 to bend at a smaller angle, so that the cleaning plate 5086 cleans the surface of the thick steel plate.
