[0021] The rotating rod 4 is fixedly penetrated through the moving plate 5, the moving plate 5 is fixedly penetrated through the U-shaped plate 6, a threaded groove is opened on the circumferential surface of the rotating rod 4, the rotation of the rotating rod 4 drives the threaded groove to rotate, and the moving plate 5 moves away from the motor 3 through the threaded groove, and the movement of the moving plate 5 drives the movement of the U-shaped plate 6.

[0022] The moving plate 5 is slidably connected to the inner wall of the equipment frame 2. A first telescopic spring rod 7 is fixedly installed on the side of the moving plate 5 away from the motor 3. The free end of the first telescopic spring rod 7 is fixedly connected to the side of the U-shaped plate 6 close to the moving plate 5. When the U-shaped plate 6 contacts the steel, it contracts through the telescopic end of the first telescopic spring rod 7, and at the same time, the U-shaped plate 6 moves towards the moving plate 5.

[0023] A telescopic spring rod two 10 is slidably installed inside the limit groove 501. The free end of the telescopic spring rod two 10 is fixedly connected to the lower part of the L-shaped plate 9. One end of the L-shaped plate 9 away from the chassis 1 is provided with an inclined plane one, and the upper part of the L-shaped plate 9 is provided with a convex surface one. A fixing groove 601 is formed inside the U-shaped plate 6. The movement of the U-shaped plate 6 drives the movement of the fixing groove 601. At the same time, the L-shaped plate 9 is reset through the telescopic end of the telescopic spring rod two 10 and limits the U-shaped plate 6 again, realizing that the length of the steel can be adapted again next time.

[0024] When this embodiment works: When it is necessary to clamp the steel, start the motor 3. The output end of the motor 3 rotates to drive the rotating rod 4 to rotate. The rotation of the rotating rod 4 drives the threaded groove to rotate. The moving plate 5 moves away from the motor 3 through the threaded groove. The movement of the moving plate 5 drives the movement of the U-shaped plate 6 to clamp the steel, realizing the fixation of the steel and preventing the steel from shaking during welding, resulting in damage to the steel.

The inclined plane of the L-shaped plate moves and contacts and squeezes the fixing plate 8, and the L-shaped plate 9 squeezes the telescopic end of the telescopic spring rod two 10 downward to contract, releasing the limit on the U-shaped plate 6. At the same time, the telescopic spring rod one 7 is reset and drives the U-shaped plate 6 to move away from the moving plate 5. The movement of the U-shaped plate 6 drives the movement of the fixing groove 601. At the same time, the L-shaped plate 9 is reset through the telescopic end of the telescopic spring rod two 10 and limits the U-shaped plate 6 again, realizing that the length of the steel can be adapted again next time.

The connecting block 116 is fixedly installed inside the moving groove 118. The U-shaped rod 117 is rotatably installed inside the connecting block 116. The movement of the fixed block 113 drives the movement of the moving frame 112 to press the steel.

[0026] One end of the moving block 114 away from the fixed block 113 is hinged to the receiving block 115. The U-shaped rod 117 is made of rubber. The movement of the receiving block 115 drives the rotation of the moving block 114, and the rotation of the moving block 114 drives the fixed block 113 to move towards the side close to the chassis 1.

[0027] The air jet device includes an air frame 121, a pressing plate 122, a pressing rod 123, an air inlet cylinder 124, an air outlet cylinder 125, an air outlet pipe 126 and an air jet frame 127. The air frame 121 is fixedly installed above the moving frame 112. The pressing plate 122 is slidably installed inside the air frame 121. The pressing rod 123 is fixedly installed at the top of the inner wall of the equipment frame 2. The air inlet cylinder 124 fixedly penetrates the top of the air frame 121. The air outlet cylinder 125 fixedly penetrates one end of the air frame 121 close to the U-shaped rod 117.

Timely cleaning of the welding slag can prevent weld defects, prevent the increase of fire hazards due to non-cleaning of the welding slag, resulting in potential safety hazards for workers. At the same time, cleaning the welding slag helps to reduce the wear of the welding equipment and extend its service life.

[0028] The upper part of the pressing plate 122 is fixedly connected to the pressing rod 123. The pressing rod 123 slidably penetrates the top of the air frame 121. The jet part of the air jet frame 127 is set as an inclined plane. The pressing plate 122 squeezes the air below upwards and sprays the air into the air jet frame 127 through the air outlet pipe 126.

[0029] During the operation of this embodiment: When clamping the steel, the moving plate 5 moves to drive the receiving block 115 to move. The movement of the receiving block 115 drives the moving block 114 to rotate. The rotation of the moving block 114 drives the fixed block 113 to move towards the side close to the chassis 1. The movement of the fixed block 113 drives the moving frame 112 to move and press the steel. Pressing the steel can prevent the steel from tilting and deforming during welding, which may cause damage to the steel and reduce the subsequent work efficiency. When the moving frame 112 moves downward, it drives the connecting block 116 to move downward. The downward movement of the connecting block 116 drives the U-shaped rod 117 to move downward. The U-shaped rod 117 rotates clockwise to contact and squeeze the steel and center the steel. By accurately centering and clamping the steel, the docking accuracy of the welded joint can be ensured, thereby reducing the deformation and error after welding and increasing the work efficiency.

[0030] When the moving frame 112 moves downward, it drives the air frame 121 to move downward. The downward movement of the air frame 121 squeezes the air below upward through the pressing plate 122, and sprays the air into the inside of the jet frame 127 through the air outlet pipe 126, and sprays it onto the surface of the chassis 1 through the jet frame 127 to clean the welding slag left over from the previous welding. Timely cleaning of the welding slag can prevent weld defects and prevent the increase of fire hazards caused by not cleaning the welding slag, which may pose potential safety hazards to workers. At the same time, cleaning the welding slag helps to reduce the wear of the welding equipment and extend its service life. At the same time, when not jetting air, the outside air can be absorbed through the air intake cylinder 124, and the gas inside the air frame 121 can be discharged to the outside through the air outlet cylinder 125, ensuring the air connection inside the air frame 121. Good air circulation helps to reduce the harmful gases and smoke generated during welding, protect the health of workers. At the same time, air circulation can help regulate the temperature of the welding area, prevent the equipment from overheating, damage the equipment, and increase the subsequent maintenance cost.
