Abstract

The invention relates to a positioning assembly connecting piece which comprises a second upper body and a second lower body; the bottom of the second upper body is sunken inwards to form a second containing groove, the second lower body comprises a first base and a matching block formed by extending outwards from the surface of the first base, and a first guide block and a second guide block arearranged on the two sides of the second containing groove respectively. Second bases located on the surface of the first base are arranged on one side of the matching block at intervals, a guide groove is defined between the matching block and the second bases, the second guide block is installed in the guide groove, and the matching block is installed in the second containing groove and fixedly connected with the second upper body; the invention further relates to a vehicle body framework, and the lower portion of a side wall A column is fixedly connected with the front portion of a front floor longitudinal beam through the positioning assembly connecting piece. The matching block is matched with the second containing groove, the second guide block is matched with the guide groove, positioning assembly between the second upper body and the second lower body is achieved; the matching block is provided with the first inclined face and the second inclined face, and when the matching block and the second containing groove are assembled, the error eliminating effect is achieved.

Description

technical field [0001] The invention relates to an automobile body structure, in particular to a positioning assembly connector and a body frame thereof. 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 part...
