The moving component 7 is a moving slide rail, which can drive the belt conveyor 8 to approach and move away from the annular slide rail 18. When the belt conveyor 8 transports the steel plate 3, it approaches the annular slide rail 18, thereby making the two symmetrical steel plates 3 move symmetrically, and the front ends gradually leave the belt end of the belt conveyor 8.

[0040] In addition, the arc adjustment unit is arranged on the arc slide rail 5; the metal arc plate 13 is arranged on the inner wall of the arc slide rail 5, the first electromagnet 14 is slidably connected to the arc slide rail 5 and is located inside the arc slide rail 5, the second driving component 15 is arranged below the first electromagnet 14, and the output end of the second driving component 15 is fixedly connected to the roller 16, and the roller 16 is in contact with the arc slide rail 5, and the second lifting component 17 is arranged below the second driving component 15, and the output end of the second lifting component 17 is fixedly connected to the welding gun 2. The second driving component 15 is a self-locking motor, and the second lifting component 17 is a cylinder; the second driving component 15 is started, driving the roller 16 to rotate, and the roller 16 contacts the arc slide rail 5, thereby driving the first electromagnet 14, the second lifting component 17 and the second driving component 15 to slide on the arc slide rail 5 to adjust the position of the welding gun 2. After reaching the appropriate position, the first electromagnet 14 is energized to generate magnetic force, and attracts the metal arc plate 13 to fix the position of the welding gun 2. At this time, the second lifting component 17 is started again to adjust the distance between the welding gun 2 and the steel plate 3.

The reinforcing component 25 is a cylinder, and when the reinforcing component 25 is started, the limit blocks 26 are driven to enter the limit grooves 27, and the inner ring 20 is limited, so that the rotating ring 19 cannot rotate, so that the steel plate 3 maintains stability during welding.
