Arc welding automatic clamp of automatic double-machine arc welding room

The automatic arc welding clamp of the automatic double-machine arc welding room comprises a machine body, a first air cylinder is installed on one side of the machine body, and a linkage rod is installed at the top end of the first air cylinder. The first air cylinder pushes the movable groove, so that the movable disc is pushed and steered through connection of the connecting shaft, and the transverse rod is steered and pushed under the action of pushing force, so that the transverse rod is perpendicular to the mounting groove from a right angle to a steered right angle, and the pressing block is driven to clamp and fix the top of a workpiece. Meanwhile, a second air cylinder pushes a connecting rod forwards, angle pushing of a fixing column is completed through the linkage effect of a movable shaft under the pushing acting force, the fixing column gradually forms a parallel angle with the machine base from the outer inclined angle through movable connection fit, and one side of the top end of the fixing co
