Abstract

The invention belongs to the technical field of multi-axis robots, and particularly relates to an industrial welding robot with a damping structure. The welding robot can generate spatter welding slag in the working process, the spatter welding slag not only affects the appearance and increases the cleaning difficulty, but also damages welding parts. The welding gun comprises a damping support, a multi-axis mechanical arm, a welding gun, a sliding ball, a shielding shell and a smoke extraction assembly, wherein the multi-axis mechanical arm is arranged on the damping support, the welding gun is fixedly connected to an end effector of the multi-axis mechanical arm, the sliding ball is connected to the outside of the welding gun in a sliding mode, the shielding shell is connected to the sliding ball in a ball mode, an elastic element is arranged between the welding gun and the shielding shell, and the smoke extraction assembly is arranged on the shielding shell and used for extracting smoke generated in a welding process. The invention collects the sputtering welding slag generated during welding of the welding gun through the shielding shell, and simultaneously adaptively changes the position state of the shielding shell according to the shape of the workpiece, so that the shielding shell can collect the sputtering welding slag when the welding gun accurately welds the workpiece.
