[0002] When factories are producing and processing building materials, they need to perform pipe welding operations. Generally, many welding tasks are done manually, but with the development of science and technology and the emergence of intelligent equipment, pipe welding robots are more adapted to social needs and improve the efficiency of industrial production.

[0003] In order to solve the problem of welding manipulators for clamping pipe fittings, a Chinese patent has issued a welding manipulator that can perform double-sided welding on pipe fittings. The announcement number is CN218612513U, which includes a manipulator body and a driving assembly fixedly connected to the bottom of the manipulator body. The front lower and upper parts of the driving assembly are respectively fixedly connected with a lower welding assembly and an upper welding assembly. By setting two lower and upper welding assemblies with the same structure and a driving assembly, pipe fittings of different diameters can be clamped, and the position of the moving seat is continuously changed in conjunction with the welding gun during the welding process, so as to achieve the purpose of continuous welding of both sides of the pipe fitting at the same time, thereby reducing the work intensity of the staff. By setting multiple second gears inside the fixed seat, and setting a fan at one end of the second gear, the rack drives the second gear to rotate when the moving seat moves, so that the fan generates wind to sweep the welding position of the pipe fitting, reduce the temperature of the surface of the pipe fitting, and facilitate the staff to remove the pipe fitting.

Therefore, a welding manipulator that is convenient for clamping pipe workpieces is proposed. Utility Model Content
