Integrated movable welding device for special-shaped side plate of automobile container

The invention discloses an automobile container special-shaped sideboard integrated moving welding device which is provided with a spinning mechanism, and the spinning mechanism comprises a spinning pipe, a rotating shaft, a rolling frame, a welding wire, a pair of rollers and a servo motor. A lock hole is formed in the side face of the end of the rolling frame. A damping piece is arranged on the inner wall of the spinning pipe and comprises a fixing disc, a first spring, a ball and a spring bolt, a sliding groove is formed in the fixing disc, a communicating groove is formed in the surface of the fixing disc and overlaid on the sliding groove, one end of the spring bolt is connected with the ball, and the other end of the spring bolt penetrates through the communicating groove and elastically stretches into the lock hole. When the lock tongue extends into the lock hole, the rolling frame can be prevented from continuously rotating due to inertia, and more welding wires can be released. When the welding wire
