Quick-release welding head of welding robot

The utility model relates to the technical field of welding robots, and provides a quick-release welding joint of a welding robot, which comprises a welding robot joint, a gas transmission connecting pipe is rotatably mounted on the outer circumferential surface of the welding robot joint, and a gas transmission joint is fixedly mounted at one end, far away from the welding robot joint, of the gas transmission connecting pipe. Two butt-joint clamping blocks are fixedly installed on the outer circumferential face of the welding robot connector below the gas conveying connecting pipe, and a butt-joint notch is formed in the bottom end of the welding robot connector. By means of the technical scheme, the problems that in the prior art, a welding head cannot be completely fixed only by means of a movable rocker, and the welding head is prone to loosening are solved, the position of an adjusting rotary drum on a welding head base body can be adjusted by rotating the adjusting rotary drum, meanwhile, the adjusting
