Abstract

The invention provides a positioning device. The positioning device comprises a positioning pin mounting structure and a mounting pedestal, wherein the positioning pin mounting structure comprises at least one positioning pin mounting position; and the mounting pedestal is used for providing a plurality of different mounting positions for the positioning pin mounting structure, and when the positioning pin mounting structure is mounted at the different mounting positions, positioning pins on the positioning pin mounting structure face different directions. As the positioning device provided by the invention is used on different welding posts, the positioning directions can be repeatedly switched, an enough welding space is left in the welding process of a workpiece, the welding quality is improved, and the manufacture cost of a fixture is lowered; and meanwhile, the positioning device is simple in structure and is easy and convenient to operate, and the structure of the fixture can be effectively optimized.

Description

technical field [0001] The invention relates to the field of fixture positioning of automobiles, in particular to a positioning device. Background technique [0002] In the fixture design process of automobiles, the positioning pin structure is widely used in the fixture design unit to ensure the accuracy of workpiece positioning to meet the requirements of workpiece welding. Usually, the distribution principle of positioning pins is that they should be as close as possible to the two sides in the long direction of the workpiece to control the degrees of freedom of the workpiece in two directions, and at the same time, the positioning pins cannot affect the welding tongs to weld the workpiece. [0003] If the same station is shared by multiple models, there are cases where the position of the positioning pin hole of the similar assembly station is slightly different, and multiple positioning pins need to be set to meet the positioning requirements of workpieces of different ...
