[0019] Preferably, a lower mounting plate is provided below the lead screw motor and the electromagnet, a limit fixing piece is provided at the middle position of the punching mechanism body, and a mounting bolt is provided on the outer wall of the limit fixing piece.

[0020] Preferably, a punching method of a punching device for processing civil air defense equipment comprises the following steps:

[0021] Step 1: Insert the inner reinforcement pipe body into the outer pipe body and place it in the middle position. Use the limit fixing parts and mounting bolts to limit and fix it. Move the upper electric clamps at both ends to the position above the pipe mouth. Use the upper electric clamps to clamp and fix the two pipes. Use the lower electric clamps to clamp and fix the lower part of the pipe mouth to prevent it from moving and deflecting.

[0022] Step 2: Use the guide rail slider and the top guide rail to move the first lifting frame and insert it into the tube, so that the ball screw passes through the tube body, and the electric lifter adjusts the insertion height. The second lifting frame moves to one end of the ball screw, and the positioning end of the screw is combined and fixed by the electromagnet and the magnetic clamping mouth;

[0023] Step 3: Start the lead screw motor to drive the dust collecting mechanism, the mobile drilling mechanism and the cleaning mechanism to move to the drilling position in the pipe in the order of front, middle and back, use the camera and the infrared distance sensor to detect the position distance between the drilling position and the inner pipe, adjust the electric lifting mechanism to make it reach the required drilling position for drilling, and when drilling the lower semicircle, use the turntable motor to drive the active turntable to rotate, so that the position of the ball screw changes, so as to achieve the effect of switching the drilling position;

[0024] Step 4: During the drilling process, the dust-containing gas is drawn into the interior by the fan, and the gas is filtered by the primary filter, high-efficiency filter and filter bag. The electric shaft drives the cleaning plate from the horizontal state to the vertical state, and the water in the water storage container is sent to the nozzle through the delivery pipe for spray cleaning. Since the cleaning plate is round, the inside of the pipe can be fully cleaned;

[0025] Step 5: After the drilling is completed, the electromagnet is powered off and demagnetized, and the second lifting frame is driven to separate from the positioning end of the screw. The first lifting frame moves to the far end, so that the ball screw moves out of the tube. The subsequent screw processing mechanism is used to screw the internal drilled holes to combine the two tube bodies, and they can still be disassembled and separated after the combination.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention can achieve the effect of two-side combination by setting the first lifting frame and the second lifting frame, and can be separated after the combination, so that the internal processing process of the pipe body can be adjusted more conveniently. The electric lifter and the top guide rail can adjust the height and position, so that the equipment can adapt to pipe bodies of different sizes and lengths. Inside the pipe, not only can the two pipe bodies be effectively punched at fixed points, but also cleaning and dust removal operations can be performed during the punching operation, making the punching operation process more environmentally friendly and improving the processing efficiency of the entire civil air defense equipment. After the entire equipment punches holes in the pipe body, the pipe body can have a detachable structure, and its exterior will not be damaged by the influence of the external punching method, and there will be no irreversibility due to welding, which is more conducive to user use.

[0028] 2. The drill rod motor drives the drill rod to rotate and punch holes. The camera takes pictures of the interior so that external users can know the internal punching process. The infrared distance sensor detects the distance between the punching point and the inner wall of the pipe. The detection data is fed back to the electric lifting mechanism controller, so that the controller drives the electric lifting mechanism to move up and down, making the punching process automatic and efficient. The electric shaft drives the cleaning disc to rotate so that the cleaning disc can switch between the horizontal and vertical states. The water storage container stores water and delivers water to the nozzle through the delivery pipe for spraying. Since the cleaning disc is circular and the nozzle is at different positions of the circle, it can effectively clean the inner wall of the pipe. The primary filter and the high-efficiency filter filter gas impurities. The filter bag strengthens the filtering effect. The fan pulls the gas. The above structure can strengthen the processing effect of the punching mechanism on the inner wall of the pipe body and can be used simultaneously during punching to improve the processing efficiency.
