[0016] Compared with the prior art, the present invention provides a punching device for punching holes on the surface of a building model, which has the following beneficial effects:

[0017] 1. A punching device for punching holes on the surface of a building model. A telescopic rod, a clamping claw, a first spring, a gear, a driving pulley and a driven pulley are arranged. The drill bit is close to the position to be punched, and the two clamping claws are respectively located on both sides of the building model. After the motor is started, the driving pulley rotates, and the driven pulley and the gear are driven to rotate through the transmission belt. The two telescopic rods move laterally under the transmission of the gear, and the two clamping claws approach each other until the building model is clamped. The drill bit is pushed by holding the handle to drill holes in the building model. During this process, the two telescopic rods continue to move laterally, and the clamping claws are supported by the building model and cannot continue to deflect. The angle between the telescopic rod and the adjacent clamping claw increases, and the first spring stretches and tends to be tightened, so that the pressure on the outer walls on both sides of the building model increases, further enhancing the clamping of the building model to keep it stable, and achieving synchronous clamping and fixing of the building model during drilling. The control process is simple and the operation is convenient.

[0018] 2. A punching device for drilling holes on the surface of a building model. By setting grooves and rollers, the drill bit penetrates deep into the building model during the drilling process, and the mounting plate gradually approaches the building model. The roller is installed on the inner side of the clamp through the groove and contacts the building model, converting the sliding friction between the clamp and the building model during the movement of the clamp into rolling friction, thereby ensuring that the clamp moves smoothly and synchronously with the drill bit.

[0019] 3. A punching device for punching holes on the surface of a building model, by arranging a second spring, a knob, a pressing ring, a threaded column, a threaded sleeve and a guide rail. In an initial state, the second spring is in a contracted state, and the pressing ring presses the guide rail after receiving the pressure from the second spring, fixing the bottom end of the handle to the bottom of the mounting plate. At this time, the handle cannot change its angle, and the knob is turned to make the threaded column move away from the threaded sleeve, and the distance between the knob and the pressing ring increases. The second spring is reset, and the pressure on the pressing ring is reduced, and the fixing ability of the bottom end of the handle is lost. The handle is turned, and the threaded sleeve leaves the socket and slides along the slide groove inside the guide rail. After adjusting the handle to an appropriate angle, the knob is rotated in the opposite direction, and the threaded column enters the threaded sleeve, and the distance between the knob and the pressing ring decreases. The second spring contracts, and the pressing ring presses the guide rail, and the handle is positioned again, which is convenient for fixing the building model at different angles, giving the device a wider range of applicability.

The two ends of the first spring 15 are fixed by the shaft sleeve 16 and the shaft seat 14, and the shaft sleeve 16 rotates relative to the clamping jaws 13 to avoid distortion of the first spring 15 during the stretching process, thereby extending the service life of the device.

[0037] In the present invention, the top of the handle 2 is rotatably connected to the mounting plate 1, and the bottom of the mounting plate 1 away from the handle 2 is fixedly connected with a guide rail 19, and a slide groove is provided inside the guide rail 19. The track of the slide groove is an arc, and the center of the arc is on the same straight line as the rotation axis of the top of the handle 2.

[0038] In the present invention, a socket 23 adapted to the slide groove is provided at the bottom of the mounting plate 1, a threaded sleeve 31 is fixedly connected to the bottom end of the handle 2, the threaded sleeve 31 is inserted into the inside of the socket 23, and the threaded sleeve 31 is slidably connected to the inside of the slide groove, a threaded column 30 is threadedly connected to the side of the threaded sleeve 31 away from the handle 2, and a knob 20 is fixedly connected to the end of the threaded column 30 away from the threaded sleeve 31, a second spring 21 is sleeved on the outside of the threaded column 30, one end of the second spring 21 is fixedly connected to the bottom of the knob 20, and a pressing ring 22 is fixedly connected to the other end of the second spring 21, the pressing ring 22 is sleeved on the outside of the threaded column 30, and a side of the pressing ring 22 away from the second spring 21 is in contact with the side of the guide rail 19, and in the initial state, the second spring 21 is in a contracted state, and the pressing The ring 22 receives the pressure from the second spring 21 and presses the guide rail 19 to fix the bottom end of the handle 2 to the bottom of the mounting plate 1. At this time, the handle 2 cannot change its angle. The knob 20 is turned to move the threaded column 30 away from the threaded sleeve 31. The distance between the knob 20 and the pressing ring 22 increases, the second spring 21 is reset, and the pressure on the pressing ring 22 decreases, losing the ability to fix the bottom end of the handle 2. The handle 2 is turned, and the threaded sleeve 31 leaves the socket 23 and slides along the slide groove inside the guide rail 19.

During this process, the two telescopic rods 29 continue to move laterally, and the clamping jaws 13 are supported by the building model and cannot continue to deflect. The angle between the telescopic rod 29 and the adjacent clamping jaws 13 increases, and the first spring 15 stretches and tends to be tightened, so that the outer walls on both sides of the building model are supported. The pressure received increases, further enhancing the clamping of the building model to keep it stable. The drill bit 6 penetrates into the building model during the drilling process, and the mounting plate 1 gradually approaches the building model. The roller 18 is installed on the inner side of the clamping jaw 13 through the groove 32 and contacts the building model, converting the sliding friction between the clamping jaw 13 and the building model during the movement of the building model into rolling friction, ensuring that the clamping jaw 13 is smoothly synchronized with the movement of the drill bit 6. After the drilling is completed, the motor 4 is controlled to reverse, the drill bit 6 leaves the building model, the two telescopic rods 29 move away from each other, and the first spring 15 is reset until the distance between the two clamping jaws 13 is larger than the width of the building model again, and the drilling of the building model is completed.
