Technical Field

[0001] The utility model relates to the technical field of automobile assembly, in particular to a hardware component for automobile assembly positioning. Background Technique

[0002] The assembly of automobile products (including the whole vehicle and assemblies, etc.) is one of the most important technological processes in the manufacturing process of automobile products. It is a technological process of assembling hundreds or thousands of various parts that have passed inspection into the whole vehicle and assemblies such as engines and transmissions according to certain technical requirements. In the automobile assembly process, according to different production programs, product structure characteristics, quality requirements, etc. of automobile products, the adopted assembly organization forms are also different, which are divided into fixed assembly, free flow assembly, forced continuous flow assembly, forced intermittent flow assembly and modular assembly.

[0003] Automobile leaf springs are the most traditional elastic elements in the automobile suspension system, with the advantages of good reliability, simple structure, short manufacturing process flow, low cost and greatly simplified structure. During the automobile assembly process, it is necessary to position and assemble the automobile leaf springs. In the existing positioning and assembly process of most automobile leaf springs, it is necessary to stack leaf springs of different lengths, and then connect and fix the leaf springs through clamps and fixing bolts. At the same time, position and assemble between the leaf springs. In this way, the positioning and assembly performance between the leaf springs is poor. At the same time, the gap between the clamp and the fixing bolt is likely to reduce the fastening performance of the positioning and assembly between the leaf springs. It is necessary to design a hardware component for automobile assembly positioning to solve the above-mentioned problems. Summary of the Utility Model
