Embodiment Construction

[0020] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0021] Such as figure 1 with figure 2 As shown, the self-positioning tool for the roof of the body-in-white includes a fixture base 1 and a support angle seat 2 under the roof; wherein, the fixture base 1 is a rectangular frame structure; there are six support angle seats under the roof, corresponding to the white One side of the roof of the vehicle body is provided with two, and the lower part of the support angle seat under the roof is fixed on the clamp base by bolts.

[0022] On the support angle seat 2 under the top cover, the adjacent two sides corresponding to the roof of the body-in-white are provided with side limit reference blocks 5, and the side limit reference blocks 5 are rubber blocks; The reference block is provided with a lower reference block 3 under the roof, and the top s...

Abstract

The invention discloses a white car body top cover self-positioning tool which comprises a fixture base, wherein a top cover lower support angular seat is arranged on the fixture base; lateral limiting standard blocks are arranged on the top cover lower support angular seat, corresponding to two adjacent sides of the white car body top cover; and movable clamping mechanisms are arranged on the top cover lower support angular seat, corresponding to the other two adjacent sides of the white car body top cover. The pressing mechanism of the positioning tool is completed by adopting a telescopic mechanism, and therefore, the assembly space of components is effectively increased, functions of quick assembly and clamping are achieved, and the operation is simple and convenient; and an elastic mechanism with a spring is arranged in the pressing mechanism, so as to absorb component assembly defects caused by external dimension tolerance and arrangement position tolerance of the components, thus being accurate and reliable in positioning.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a self-positioning tool for a roof cover of a body in white. Background technique [0002] In the body manufacturing industry, the positioning accuracy of tooling has a crucial impact on the dimensional accuracy of the body-in-white. Due to the special process of the top cover parts, the traditional pin positioning method cannot be used in the positioning welding, and the profile positioning is used in most cases. [0003] Generally, the roof of the vehicle body is stamped and formed by a thin plate, and the area of ​​a single part is large, and the elastic deformation of the part is relatively large. At present, the clamping mechanism with a fixed stroke cannot be accurately positioned, and the positioning operation is cumbersome, and it is easy to deform the part clamp, which affects the product quality. Contents of the invention [0004] Aiming at the defi...
