AI Technical Summary

Technical Problem

Existing automated hood assembly equipment has limited applicability, only suitable for the same vehicle model, and suffers from problems such as large structural volume, heavy weight, and springs that are prone to rust and jamming.

Method used

The C-shaped hanger design integrates the tightening gun, tooling positioning components, and front cover positioning components at the bottom of the hanger. The center of gravity of the tooling is adjusted by the center of gravity adjustment mechanism, and automatic tightening is achieved by combining the centering mechanism and floating cylinder, which reduces the size and weight of the equipment and improves its applicability.

Benefits of technology

It achieves adaptability to various vehicle models, reduces equipment maintenance costs, improves assembly efficiency and precision, and reduces equipment size and weight.
