Abstract

The invention relates to a positioning assembly part which comprises a first upper body and a first lower body which are assembled and fixed with each other; and the first upper body comprises a firstupper body base and a first upper connecting piece fixed on the outer side surface of the first upper body base; the first lower body comprises a first lower body base and a first lower connecting piece fixed to the surface of the inner side of the first lower body base and coaxial with the first lower body base, the axis of the first upper body base is perpendicular to the axis of the first upper connecting piece, and the first lower connecting piece is provided with a first containing groove penetrating through the first lower body base. The first upper connecting piece is arranged in the first containing groove and rotates around the axis of the first lower body base; the invention further relates to a vehicle body framework. The upper portion of a lower vehicle body column A is fixedly connected with the upper portion of a side wall column A through a positioning assembly part. The first upper body provided with the positioning assembly part rotates around the axis of the first lower body, multi-direction and multi-angle assembly is achieved, and the application mode is flexible.

Description

technical field [0001] The invention relates to an automobile body structure, in particular to a positioning assembly and its body frame. Background technique [0002] Automobile manufacturing is divided into four major production processes: stamping, welding, painting, and final assembly. The body frame of an automobile needs to go through the three major processes of die stamping, welding assembly, and coating and anticorrosion before entering the assembly workshop and other auto parts. Matched and installed into automotive products, the body frame is an important carrier of the vehicle and the only core component that runs through the four major production processes. [0003] In traditional automobile body manufacturing, hundreds of stamping parts are welded into dozens of sub-assemblies, which are then connected through assembly welding lines, and finally welded into body frame assemblies through assembly lines. There are many types and quantities of parts, which require...
