[0002] The robot welding tongs is a key external device in the robot welding system, which is used to grab the weldment and provide and maintain welding power. It transmits welding energy in the form of welding current through electric current, and collects energy from the arc to heat and melt the weldment. The welding tongs are usually composed of a tongs body, a tongs head and a tongs handle. The design needs to consider factors such as the strength and rigidity of the tongs body, the gripping range of the tongs head, the weight and the ease of operation. Using a robot and a welding tongs to complete welding can achieve more flexible and efficient welding production and improve welding quality. Publication No. CN216503093U discloses a modular robot welding tongs, including a connecting flange, a U-shaped bracket, a transformer, an insulating seat, a fixed large pole arm, a fixed small pole arm, an electrode connecting plate one, a movable large pole arm, and an electrode connecting plate two , movable small pole arm, impact-proof welding insulating mounting seat structure, horizontally movable guide rod structure and easy-to-replace electrode cap structure, the middle part of the right part of the connecting flange is bolted with a U-shaped bracket; the left side of the inside of the U-shaped bracket is bolted with a transformer; the upper right side of the U-shaped bracket is bolted with an insulating seat, and the middle part of the upper part of the insulating seat is bolted to one end of the fixed large pole arm, wherein the other end of the fixed large pole arm is bolted with a fixed small pole arm. In actual application of the above technology, when the robot welding clamp is working, it is necessary to weld the weldment, and a large amount of heat will be generated in this process. When the heat on the surface of the robot welding clamp is too high, the welding efficiency of the robot welding clamp will be greatly reduced, and long-term heat overload will greatly reduce the service life of the robot welding clamp.
