The device includes a frame, a welding head, a workbench, a cylinder, a fixing device, a slider, a bidirectional screw and a servo motor. The welding head is fixedly connected to the bottom of the welding machine, the welding machine is connected to the cylinder through a piston rod, and the top of the cylinder is movably connected to the fixed block on the top of the frame through an axle pin.
