Multi-arm welding robot

The invention provides a multi-arm welding robot which comprises a robot base and arms. The arms are located on the robot base, the left side and the right side of the base are respectively provided with a lifting frame, a lifting table is arranged on the base, the lifting table is located on the left side of the lifting frame on the left side, a lifting mechanism is arranged in the middle of the base, the arms are arranged on the lifting frames, the lifting table and the lifting mechanism, welding guns are arranged on the arms, and the arms are bent and adjustable. The multiple arms are arranged, multi-direction welding work can be carried out on a component at the same time, the welding guns can be combined into distribution patterns suitable for different welding requirements through the bent adjustability of the arms, and continuous welding of the welding guns in the movement process is achieved through the movable characteristic of the arms. The multi-arm welding robot is simple in structure, low in cost and particularly suitable for welding components with large welding areas or multiple welding positions, and the work efficiency of the welding robot is improved.
