Description

Technical Field

[0001] The utility model relates to the technical field of laser welding equipment, in particular to a laser welding equipment used for bridge production. Background Art

[0002] The bridge is a commonly used device in electrical engineering installation. It is mainly used to support wires and cables to achieve standardized, systematic and universal laying of wires and cables. The bridge is composed of trays, straight sections of ladders, bends, accessories, supports and hangers, etc. It is a continuous system with a rigid structure.

[0003] The production of bridge frames generally consists of direct bending of metal plates or welding of multiple metal parts to each other. When some bridge frames are welded and assembled, it is necessary to first weld one end of multiple connecting beams to one side of the same side beam, and then, contact one side of another side beam with one end of multiple connecting beams and clamp them with a clamp. Then, one end of the connecting beam is welded to the side beam through welding equipment to complete the welding of a bridge frame section. However, when welding two side beams to multiple connecting beams, this welding operation method requires multiple connecting beams to be welded to one of the side beams in advance, which increases the welding time. At the same time, if the bridge frame is welded manually, the overall welding efficiency will be low. If the bridge frame components are welded with the help of a welding robot arm, the multiple bridge frame components cannot be fixed quickly, which affects the welding accuracy.
