Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding gun fixing and translation regulating mechanism. Background Art

[0002] At present, when using a welding gun to weld a product, it is usually necessary to rotate the welding gun to maintain a suitable angle with the product. However, the existing welding gun adjustment method mostly adopts a welding method in which the workbench moves, and the welding gun body does not move as the workbench moves. However, due to the heterogeneity of product parts, the welding gun needs to be moved and also needs to be swung.

[0003] At present, in the prior art, for example, a Chinese patent with a publication number of CN219053390U discloses a welding gun adjustment mechanism, which adjusts the height of the welding gun through a lifting assembly, and then drives the rotating shaft to rotate through a driving assembly, thereby adjusting the direction of the welding gun, and then turning on the motor so that the mounting plane drives the fixing plate to rotate about the axis of the first driven gear, thereby achieving the purpose of adjusting the welding gun angle and facilitating multi-angle welding. However, the welding gun of the device is fixed, which makes it very inconvenient to perform maintenance and repair work on the welding gun. In view of this, we propose a welding gun fixed translation adjustment mechanism. Utility Model Content
