The output end of the first stepper motor drives the first screw to rotate, so that the two sets of clamping plates approach each other along the first guide rod, clamping the steel structure plate on the end of the conveyor. Under the action of the mechanical arm, the mechanical arm and the first clamping mechanism cooperate to place the rear end of the steel structure plate on the inner bottom end of the rear clamping frame. S2, then the output end of the rear cylinder is extended, driving the rear pressure plate to move downward, so as to clamp and fix the rear end of the steel structure plate, and the output end of the fifth stepper motor drives the fifth screw rod to rotate, so that the anti-splash frame moves downward, and the anti-splash frame covers the top of the rotating plate, and the output end of the second stepper motor drives the second screw rod to rotate, so that the first movable plate reciprocates back and forth along the second guide rod, so as to drive the mounting plate to reciprocate back and forth, and the output end of the third stepper motor drives the third screw rod to rotate, so that the second movable plate reciprocates left and right along the third guide rod, so as to drive the mounting plate to reciprocate left and right, and by controlling the extension or contraction of the output end of the electric push rod, the mounting plate is driven to move downward or upward, so that the drill bit moves in the horizontal, vertical and vertical directions, so as to drill the top front end of the steel structure plate; S3.

[0033] In order to clearly describe the working principle of the present invention, we use Figure 1 The perspective is explained as follows: S1. An external conveyor is provided on the left side of the box 1. The conveyor transports the steel structure plate to be drilled. The output end of the first stepper motor 204 drives the first screw 202 to rotate, so that the two sets of clamping plates 205 approach each other along the first guide rod 203, clamping the steel structure plate on the end of the conveyor. Under the action of the mechanical arm 101, the mechanical arm 101 and the first clamping mechanism 2 cooperate to place the rear end of the steel structure plate on the inner bottom end of the rear clamping frame 306. S2, after the output end of the rear cylinder 307 is extended, the rear pressure plate 308 is driven to move downward, so that the rear end of the steel structure plate is clamped and fixed, and the fifth screw rod 602 is driven to rotate by the output end of the fifth stepper motor 604, so that the anti-splash frame 605 moves downward, and the anti-splash frame 605 covers the top of the rotating plate 103, and the second screw rod 402 is driven to rotate by the output end of the second stepper motor 404, so that the first movable plate 405 reciprocates back and forth along the second guide rod 402, so as to drive the mounting plate 415 to reciprocate back and forth, and the third screw rod 407 is driven to rotate by the output end of the third stepper motor 409, so that the second movable plate 410 reciprocates left and right along the third guide rod 408, so as to drive the mounting plate 415 to reciprocate left and right, and the mounting plate 415 is driven to move downward or upward by controlling the extension or contraction of the output end of the electric push rod 411, so that the drill bit 104 moves in the horizontal, vertical and vertical directions, so as to drill the top front end of the steel structure plate; S3. Due to the clamping method, there is a blind spot for drilling at the rear end of the steel structure plate, and drilling is impossible. At this time, the output end of the servo motor 304 drives the threaded rod 302 to rotate, so that the two sets of movable blocks 305 approach each other, and drive the two sets of clamping frames 306 approach each other, so that the front end of the steel structure plate enters the interior of the front clamping frame 306, and the output end of the front cylinder 307 extends, driving the front pressure plate 308 to move downward, thereby clamping and fixing the front end of the steel structure plate, and the output end of the rear cylinder 307 contracts, so that the rear pressure plate 308 moves upward, releasing the clamping and fixing of the rear end of the steel structure plate, and then the output end of the servo motor 304 rotates in the opposite direction, so that the two sets of movable blocks 305 move away from each other until they are reset, thus exposing the blind spot at the rear end of the steel structure plate, and the drilling steps can be repeated to drill the top rear end of the steel structure plate; S4. During the punching process, due to the shielding of the anti-splash frame 605, even if the generated debris splashes, it is only inside the anti-splash frame 605, ensuring a clean environment. When cleaning and collecting the debris, the output end of the fifth stepper motor 604 drives the fifth screw rod 602 to rotate, so that the anti-splash frame 605 moves upward to the reset state, and then the output end of the first drive motor 102 drives the rotating plate 103 to flip, so that the debris falling on the top of the rotating plate 103 falls into the inside of the box body 1 for collection; S5. If the drill bit 104 is damaged during the drilling process, the fourth screw rod 502 is driven to rotate by the output end of the fourth stepper motor 504, so that the storage member 505 moves backward along the fourth guide rod 503, thereby driving the drill bit 104 stored thereon to move backward. Under the action of the output end of the third stepper motor 409, the second movable plate 410 moves to the right along the third guide rod 408, thereby driving the installation disk 415 to move to the right. The installation assembly can quickly install or remove the drill bit 104, and realize the return of the old drill bit 104 to the storage slot on the storage member 505, and the clamping and fixing of another new drill bit 104, which is convenient and fast and meets the needs of the staff.

A method for drilling holes in a building steel structure, used to implement a drilling device for a building steel structure according to any one of claims 1 to 9, characterized in that: include: S1. An external conveyor is provided on the left side of the box (1). The conveyor conveys the steel structure plate to be drilled. The output end of the first stepper motor (204) drives the first screw (202) to rotate, so that the two sets of clamping plates (205) approach each other along the first guide rod (203) to clamp the steel structure plate at the end of the conveyor. Under the action of the mechanical arm (101), the mechanical arm (101) and the first clamping mechanism (2) cooperate to place the rear end of the steel structure plate on the inner bottom end of the rear clamping frame (306); S2, the output end of the rear cylinder (307) is extended, driving the rear pressure plate (308) to move downward, thereby clamping and fixing the rear end of the steel structure plate, and the output end of the fifth stepper motor (604) drives the fifth screw rod (602) to rotate, so that the anti-splash frame (605) moves downward, and the anti-splash frame (605) covers the top of the rotating plate (103). The output end of the second stepper motor (404) drives the second screw rod (402) to rotate, so that the first movable plate (405) moves back and forth along the second guide rod (402). The third stepping motor (409) drives the third screw rod (407) to rotate, so that the second movable plate (410) moves back and forth along the third guide rod (408), thereby driving the mounting plate (415) to move back and forth. The output end of the electric push rod (411) is controlled to extend or contract, so that the mounting plate (415) is driven to move downward or upward, so that the drill bit (104) moves in the horizontal, vertical and vertical directions, thereby drilling the top front end of the steel structure plate. S3. Due to the clamping method, there is a drilling dead angle area at the rear end of the steel structure plate, and drilling cannot be performed. At this time, the output end of the servo motor (304) drives the threaded rod (302) to rotate, so that the two groups of movable blocks (305) are close to each other, and the two groups of clamping frames (306) are driven to approach each other, so that the front end of the steel structure plate enters the interior of the front clamping frame (306). The output end of the front cylinder (307) is extended, driving the front pressure plate (308) to move downward, thereby clamping and fixing the front end of the steel structure plate, and the output end of the rear cylinder (307) is contracted, so that the rear pressure plate (308) moves upward, releasing the clamping and fixing of the rear end of the steel structure plate. After that, the output end of the servo motor (304) rotates in the opposite direction, so that the two groups of movable blocks (305) move away from each other until they are reset, thereby exposing the dead angle area at the rear end of the steel structure plate. Then, the drilling steps can be repeated to drill the top rear end of the steel structure plate. S4. During the punching process, due to the shielding of the anti-splash frame (605), even if the generated debris splashes, it is only inside the anti-splash frame (605), ensuring a clean environment. When cleaning and collecting the debris, the output end of the fifth stepper motor (604) drives the fifth screw rod (602) to rotate, so that the anti-splash frame (605) moves upward to a reset state, and then the output end of the first drive motor (102) drives the rotating plate (103) to flip, so that the debris falling on the top of the rotating plate (103) falls inside the box (1) for collection; S5. If the drill bit (104) is damaged during the drilling process, the output end of the fourth stepper motor (504) drives the fourth screw rod (502) to rotate, so that the storage member (505) moves toward the rear side along the fourth guide rod (503), thereby driving the drill bit (104) stored thereon to move toward the rear side. Under the action of the output end of the third stepper motor (409), the second movable plate (410) moves toward the right side along the third guide rod (408), thereby driving the installation plate (415) to move toward the right side. The installation assembly can quickly install or remove the drill bit (104), realize the old drill bit (104) is put back into the storage slot on the storage member (505), and clamp and fix another new drill bit (104), which is convenient and fast, and meets the needs of the staff.
