Description

A self-made car body frame joint car tire mold

technical field

The utility model belongs to the technical field of vehicle body frame combined vehicles, in particular to a self-made vehicle body frame combined vehicle tire tool for passenger cars.

Background technique

Nowadays, in the technological process of passenger cars, the frame assembly and welding of the body is the most critical process in the production of combined passenger car bodies. This process not only determines the assembly dimensional accuracy of the body, but also restricts the production efficiency of the body welding line. At present, large companies at home and abroad, in order to improve assembly accuracy and production efficiency, mainly use special assembly equipment, through which the body positioning assembly welding can be completed at one time, and the investment in this equipment is huge.
