Description

Technical Field

[0001] The utility model relates to the field of welding, in particular to the field of improved technology of welding manipulators, and specifically to a welding head with adjustable angle on a welding cross manipulator. Background Art

[0002] The angles of the welding heads on existing welding cross manipulators are mostly fixed and suitable for processing horizontally placed barrel-shaped parts. However, a tooling is designed for processing conical barrel-shaped parts. In order to make the conical barrel-shaped parts rotate more stably during welding, it is necessary to turn them over to add a limiting surface. When processing conical barrel-shaped parts, the whole is in an inclined state. At this time, the initial linear angle of the welding head cannot fit well with the surface of the conical barrel-shaped parts. Moreover, according to the outer diameter specifications and welding points of the conical barrel-shaped parts required to be processed on this kind of tooling, the welding head needs to be adjusted. If a welding head with a specific angle needs to be made for each batch of conical barrel-shaped parts of the same specification, the cost is too high. Therefore, it is necessary to design a welding head with adjustable angle on a welding cross manipulator. Summary of the Invention
