Technical Field

[0001] The utility model relates to the field of welding robots, in particular to a welding gun fixing frame of a welding robot. Background Art

[0002] A welding robot is a robot used to perform welding work. It is a robot with a motion platform and a manipulator integrated into one, and equipped with auxiliary devices such as a welding gun. It can automatically complete designated welding tasks under the operation of a controller. They have the advantages of high precision, good stability, high efficiency, and good repeatability, and can greatly improve production efficiency and product quality. When the welding robot is welding, a welding gun fixing frame is required to fix the welding gun for welding work. During the welding process, existing welding robots usually use a limit frame to fix the welding gun body at the top of the transmission arm. Since the welding angles for different workpieces are relatively different, it is difficult for the limit frame to fix the welding gun during welding to provide the best welding angle and position, resulting in uneven welding or poor weld quality, reducing the overall welding quality and affecting the strength of the welded structure. Therefore, we proposed a welding gun fixing frame for a welding robot to solve the above-mentioned problems. Utility Model Content
