Full-automatic welding device and method for reinforcing ring, rear cover and accessory of bridge type assembly

Abstract

The invention discloses a full-automatic welding device and method for a reinforcing ring, a rear cover and an accessory of a bridge type assembly. The device comprises a supporting frame and a welding assembly arranged on the periphery of the supporting frame. The supporting frame is of a U-shaped structure, a bearing table of a U-shaped structure is installed in the supporting frame, and an equipment table is installed in the bearing table. The welding assembly comprises a welding wire barrel, a welding machine, a robot welding arm and a gun cleaning station, the centers of the outer walls of the two sides, away from each other, of the bearing table are rotationally connected with the inner wall of the supporting frame, a first motor is installed in one side of the supporting frame, anda fixing cavity is formed in the position, close to the center, in the bearing table. The center of the bottom side of the equipment table is connected with the top face of the fixing cavity through arotating roller, a second motor is installed in the fixing cavity, and a power output shaft of the second motor is fixed to the end portion of the rotating roller. Through cooperative use of all theabove devices, the labor expenditure of workers can be reduced, in addition, welding points can be welded one by one through deflection of a workpiece, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field related to automatic welding equipment, in particular to a fully automatic welding device and welding method for a bridge assembly reinforcement ring, a rear cover, and accessories. Background technique [0002] When the bridge assembly is welded, the staff needs to walk back and forth on the side of the bridge assembly to find the welding point, but this method is inefficient and will increase the workload of the staff, and the bridge assembly The distribution of welding points is relatively scattered, and some hoisting equipment is needed to flip the bridge assembly, which will cause certain safety hazards to nearby workers. Although there are welding robots that can automatically identify welding points, the cost is too high. High, resulting in excessive investment in the construction of a production line. Contents of the invention [0003] The object of the present invention is to provide a bridge typ...
