Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3, the utility model provides an embodiment: a round tube punching machine for ship maintenance, comprising a workbench 1, the interior of the workbench 1 is fixedly connected with a fixed frame 2, the bottom of the workbench 1 is fixedly connected with a cylinder 3, the output end of the cylinder 3 is fixedly connected with a push block 4, the outer wall of the push block 4 is slidably connected to the interior of the workbench 1, the outer wall of the push block 4 is slidably connected with a trapezoidal slider 5, the outer wall of the trapezoidal slider 5 is provided with a roller 6, the outer wall of the roller 6 is rotatably connected with a special-shaped plate 7, the outer wall of the special-shaped plate 7 is rotatably connected with a rotating block 8, the outer wall of the rotating block 8 is fixedly connected with a telescopic rod 9, the outer wall of the telescopic rod 9 is sleeved with a spring 10, both ends of the spring 10 are fixedly connected to the outer wall of the rotating block 8, the outer wall of the special-shaped plate 7 is rotatably connected to the inner wall of the fixed frame 2, the outer wall of the special-shaped plate 7 is rotatably connected with a clamping plate 11, and the lower surface of the workbench 1 is provided with an anti-slip component;

[0024] Specifically, first, the push block 4 is driven to move through the output end of the cylinder 3 inside the workbench 1. The movement of the push block 4 is not random. The inclined surface of the push block 4 drives the trapezoidal slider 5 to slide inside the workbench 1, so that the trapezoidal slider 5 can move up and down, and the inclined surfaces on both sides of the trapezoidal slider 5 push the roller 6 to rotate, thereby further driving the middle part of the special-shaped plate 7 to rotate inside the fixed frame 2. At this time, one end of the special-shaped plate 7 drives the rotating block 8 to move to both sides, thereby driving the spring 10 to stretch, because the stretched spring 10 will be Subsequent operations provide important driving force, and then the other end of the special-shaped plate 7 drives the clamp 11 to move. The movement of the clamp 11 is coordinated with the clamp 11 on the top of the trapezoidal slider 5, and the round tube is clamped and fixed together to ensure that the round tube always maintains a stable position during the processing to prevent it from accidental movement. Finally, the trapezoidal slider 5 is driven back to its original position by the cylinder 13. At this time, the spring 10 is no longer under force and can rebound naturally. With the help of this elastic force, the special-shaped plate 7 can be pulled back to its original position to achieve the fixation and release of the round tube.

[0025] Reference Figure 1 and Figure 4 The anti-skid assembly includes an anti-skid pad 12, the upper surface of the anti-skid pad 12 is fixedly connected to the lower surface of the workbench 1, the bottom of the workbench 1 is fixedly connected to a motor 14, the output end of the motor 14 is fixedly connected to a gear 15, the interior of the workbench 1 is fixedly connected to a fixed ring 13, the outer wall of the gear 15 is rotatably connected to the inner wall of the fixed ring 13, the interior of the fixed ring 13 is rotatably connected to a gear ring 16, the gear 15 is meshed with the gear ring 16, the outer wall of the gear ring 16 is fixedly connected to a sliding sleeve 17, the outer wall of the sliding sleeve 17 is fixedly connected to a sliding block 18, the outer wall of the sliding block 18 is slidably connected to the outer wall of the fixed ring 13, a sliding groove 19 is provided inside the fixed ring 13, the interior of the sliding block 18 is fixedly connected to a cylinder 20, and the output end of the cylinder 20 is fixedly connected to a drill bit 21;

[0026] Specifically, first, the output end of the motor 14 inside the workbench 1 is used to drive the gear 15 to rotate. Due to the meshing connection between the gear 15 and the gear ring 16, the gear ring 16 can rotate with the rotation of the gear 15, which not only ensures the continuity of the equipment operation, but also greatly improves the transmission efficiency. The rotation of the gear ring 16 further drives the sleeve 17 to rotate inside the fixed ring 13, ensuring that it can rotate smoothly. The rotation of the sleeve 17 drives the sliding block 18, and the sliding block 18 is connected to the drill bit 21. The drill bit 21 can rotate with the rotation of the sliding block 18 to prepare for the next drilling operation. Finally, the cylinder 20 drives the drill bit 21 to drill holes in the round tube, achieving an all-round drilling effect.

[0027] Working principle: When the round tube punching machine for ship maintenance is needed, first pass the round tube through the fixing ring 13 and place it in the middle of the fixing frame 2, then drive the push block 4 to move through the output end of the cylinder 3, so that the push block 4 slides inside the trapezoidal slider 5, and then drives the trapezoidal slider 5 to move up and down, and then through the movement of the trapezoidal slider 5, the rollers 6 on both sides roll on the outer wall of the trapezoidal slider 5, so that the middle part of the special-shaped plate 7 rotates inside the fixing frame 2, so that one end of the special-shaped plate 7 drives the spring 10 to stretch through the rotating block 8, and then the other end of the special-shaped plate 7 drives the clamping plate 11 to move, and cooperates with the clamping plate 11 on the top of the trapezoidal slider 5. The round tube is clamped and fixed, and then the trapezoidal slider 5 is driven to return to its original position by the cylinder 1 3. At this time, the spring 10 is no longer subjected to force and rebounds to pull the special-shaped plate 7 back to its original position, thereby releasing the round tube and facilitating the next use. The output end of the motor 14 is then used to drive the gear 15 to rotate, so that the gear ring 16 rotates in response to the rotation of the gear 15, thereby driving the sliding sleeve 17 to rotate inside the fixed ring 13 through the rotation of the gear ring 16, and then driving the drill bit 21 to rotate around the fixed ring 13 through the sliding block 18, and finally driving the drill bit 21 to drill holes in the round tube through the cylinder 2 20, thereby achieving an all-round drilling effect.
