However, the key process that affects the welding accuracy of the box beam is welding. At present, the welding of box beams mainly relies on the clamps at both ends of the positioner to achieve welding at different positions of the box beam. However, due to the large size of the box beam structure, the box beam end fixing clamp of the positioner adopts the traditional four-claw chuck four-way positioning, which requires alignment, centering and clamping from four directions. The centering process is very cumbersome and wastes a lot of work hours. It is inefficient and difficult to guarantee the centering accuracy. Therefore, there is an urgent need for a clamp with reasonable design, simple structure and fast centering and clamping to solve the problems that have been bothering technicians in the prior art.
