Abstract

The invention belongs to the technical field of automobile assembly and provides a positioning tooling. The positioning tooling comprises a clamp body and a first connecting rod which is rotatably mounted on the clamp body around a first revolving shaft, wherein the first connecting rod is provided with at least two transmission ends; each transmission end is rotatably connected with a second connecting rod around a second revolving shaft; the second connecting rods are rotatably connected with positioning pin shafts around third revolving shafts; the positioning pin shafts are mounted on the clamp body along the axes of the positioning pin shafts in a sliding way; and the first revolving shaft, the second revolving shafts and the third revolving shafts are parallel. According to the positioning tooling, at least two positioning pin shafts can be driven simultaneously by a connecting rod mechanism; during assembly, a body in white which requires two adjustable positioning can be positioned; the number of toolings is reduced, and the interference among multiple toolings is avoided, so that the operation is convenient; and one tooling is used for positioning, the mounting errors among the toolings are reduced, the positioning is accurate, and the positioning precision is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile assembly, and in particular relates to a positioning tool. Background technique [0002] In the welding and manufacturing process of automobile bodies, the accuracy of the body-in-white is the main indicator of the welding process level. High-precision body-in-white can not only improve the assembly of assembly parts, but also improve the quality of the vehicle. The diversification of automobile body-in-white structures results in the positioning holes of many body panels not parallel to the body line, resulting in an angle between the positioning pins of the welding fixture and the body line, and the panels cannot be taken out directly from the fixture along its axis, thus requiring positioning pins With telescopic function. The existing positioning tool usually only has one telescopic positioning pin. If two telescopic positioning pins are required at the same time, two positioning tools are...
