Automatic welding device of industrial robot

The automatic welding device of the industrial robot comprises a base and a welding table, the welding table is fixedly connected to one side of the top end of the base, a shell is arranged on the other side of the top end of the base, and a rotating seat is movably connected to one side of the bottom end in the shell. According to the automatic welding device of the industrial robot, the gear, the rack, the stepping motor, the sliding rail and the sliding block are arranged, when the automatic welding device is used, the stepping motor is started, the stepping motor drives the gear to rotate in a stepping mode, the gear pushes the shell through the rack, the sliding block at the bottom of the shell slides in the sliding rail, and therefore the shell slides; therefore, the industrial welding robot can move step by step, the welding position can be adjusted through step-by-step movement, multi-point welding of a workpiece is facilitated, and the problems that the welding position cannot be adjusted through ste
