Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a driving structure of a welding manipulator. Background Art

[0002] Welding is a process in which two or more similar or dissimilar materials are connected into one through the combination and diffusion of atoms or molecules. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasound. When welding parts, it is necessary to use a welding robot for intelligent welding.

[0003] For example, an intelligent welding robot provided by authorization number CN217647787U provides a limit slide bar, an adjusting sleeve, a first servo motor and a threaded rod. When welding parts, the first servo motor is started. Since the adjusting sleeve and the threaded rod are matched, the first servo motor drives the threaded rod to rotate forward so that the adjusting sleeve can descend on the outside of the threaded rod. The descent of the adjusting sleeve can drive the first connecting plate and the second connecting plate to descend. The descent of the second connecting plate can make the welding head descend to weld the parts. A limit slide bar is provided on one side of the threaded rod. The limit slide bar can limit the adjusting sleeve to prevent the adjusting sleeve from rotating on the outside of the threaded rod. The welding head needs to be raised to start the first servo motor, and the first servo motor drives the threaded rod to reverse. The provision of the first servo motor and the threaded rod can facilitate the lifting and lowering of the welding head, thereby improving the welding work efficiency.

[0004] The existing welding device may cause damage to the welding head after working for a long time, and the welding head of the welding equipment is mostly an integrated structure, so it is difficult to replace the welding head. Utility Model Content
