Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a position switching mechanism and a positioning fixture for automobile welding. Background technique [0002] In order to meet the aesthetic needs of different groups of people as much as possible, various car designs and shapes emerge in endlessly, resulting in a wide variety of cars produced by car manufacturers. Correspondingly, for cars of different shapes, the length and width of the body vary greatly. When welding different body-in-white, it is necessary to use positioning fixtures of different specifications, and even add a new processing station to realize welding, resulting in increased investment costs and a waste of space. [0003] Therefore, it is a technical problem to be solved that it is necessary to use positioning fixtures of different specifications when welding and assembling different car body parts. Contents of the invention ...
