Cleaning brushes 13 are arranged on the sides of the arc plates 12 close to each other.

[0023] Specifically, the first motor 5 drives the bidirectional lead screw 3 to rotate. When rotating clockwise, the moving blocks 4 on both sides move closer to each other, and when rotating counterclockwise, the moving blocks 4 move away from each other, which can drive two steel structures closer to each other for welding.

[0024] Preferably, the outer side of the first rotating gear 9 is meshed and connected with the outer side of the first transmission gear 10. There are two first hydraulic rods 11 and two arc plates 12, and the two are symmetrically arranged.

[0025] Specifically, the first rotating gear 9 drives the first transmission gear 10 to rotate, and the first transmission gear 10 can drive the rotating cylinder to rotate. The two symmetrical first hydraulic rods 11 can drive the arc plates 12 to move closer to or away from each other, and thus can be adjusted according to steel structures of different sizes.

[0026] Preferably, the output end of the first motor 5 is fixedly connected to the left end of the bidirectional lead screw 3. The outer side of the moving block 4 is slidably connected to the inner wall of the installation groove 2, and the lower part of the moving plate 6 is slidably connected to the surface of the workbench 1.

[0035] Working principle: The second hydraulic rod 15 drives the clamping plates 16 to fix the steel column. Then, during welding, the third hydraulic rod 22 drives the welding machine 23 to move downward to start welding the steel column. During welding, the third motor 18 can drive the second rotating gear 19 to rotate.
