The invention discloses an industrial painting robot with a regulating function, and relates to the technical field of industrial robots. The industrial painting robot comprises a base and a mechanical arm, the end of the mechanical arm is provided with a rotating frame; the rotating frame is provided with four spraying claws through two regulating mechanisms; the spraying claws are provided withspraying nozzles; the spraying claws are hinged with auxiliary spraying claws through first telescopic rods; and the auxiliary spraying claws are provided with spray nozzles. According to the industrial painting robot, the movement of parallelogram connecting rod mechanisms is regulated through the driving control of second telescopic rods, and then the opening and closing degree between the fourspraying claws is regulated; multi-angle spraying is carried out on special-shaped parts to be machined through the plurality of spray nozzles at the same time, so that the joint wear caused by the fact that a robot wrist rotates all the time is avoided, the machining efficiency is effectively improved, and the service life of the robot is prolonged; and the relative position between the auxiliaryspraying claws and the spraying claws can be regulated through the first telescopic rods, the spray nozzles on the auxiliary spraying claws can be selected to spray according to the machining requirements of the special-shaped parts to be machined, so that the flexibility of the robot is improved.
