An auxiliary assembly tool for the lower arm of the middle door

Abstract

The invention relates to an auxiliary assembly tool for a lower arm of a middle door capable of improving assembly quality. A connecting plate (1) comprises a bottom connecting plate, a left connecting plate (1-2) and a right connecting plate (1-3). The left and right ends of the bottom connecting plate are respectively oblique upwards and extend outwards. A movable connecting plate (4) comprises a parallel positioning surface (4-1) and a horizontal positioning surface (4-2). One end of the horizontal positioning surface faces downwards and vertically extends from one end of the parallel positioning surface and the lower end of the horizontal positioning surface is connected with the bottom connecting plate in the manner of adjusting the position of a vertical direction. The movable connecting plate further comprises an oblique positioning surface (4-3). The oblique positioning surface extends downwards from the other end of the horizontal positioning surface and connected with the upper portion of a lower connecting plate (5). The lower end of the lower connecting plate is provided with a positioning hook (5-1) adapted to the left end of the lower arm of the middle door. Two of three positing parts (2) are respectively connected with tops of the left connecting plate and the right connecting plate. One positioning part is arranged on the upper surface of the parallel positioning surface. The three positioning parts are respectively adapted to two buckle installing holes of an interior trimming panel and a positioning hole in the middle of the lower arm of the middle door.

Description

technical field [0001] The invention belongs to assembly tooling for automobile parts, in particular to an auxiliary assembly tooling for the lower arm of a middle door. Background technique [0002] At present, the auxiliary assembly tooling for the lower arm of the middle door adopted by some automobile manufacturers includes a planar connecting plate, connecting supports respectively arranged on the four sides of the connecting plate and nine positioning pieces arranged on the positioning supporting member, as well as design Corresponding positioning holes on the center door. When assembling the lower arm of the middle door, the middle door is positioned through 9 positioning parts and the corresponding positioning holes arranged on the middle door, and then the lower arm of the middle door is assisted in assembly. The main defect is that the 9 positioning parts and the design The processing accuracy of the corresponding positioning holes on the middle door is not easy t...

Problems solved by technology

When assembling the lower arm of the middle door, the middle door is positioned through 9 positioning parts and the corresponding positioning holes arranged on the middle door, and then the lower arm of the middle door is assisted in assembly. The main defect is that the 9 positioning parts and the design The processing accuracy of the corresponding positioning holes on the middle door is not easy to be guaranteed, which makes it difficult to locate the middle door, and leads to poor assembly accuracy of the lower arm of the middle door, resulting in the assembly of the middle door with the lower arm of the middle door assembled on the vehicle body There is an inconsistent gap between the rear middle door and the body, and the poor assembly quality affects the appearance quality. Adjustments are needed to eliminate the inconsistent gap between the middle door and the body, which not only affects the assembly progress, but also makes the high assembly cost
