Based on the thread slip-tooth occurred when the front suspension assembly upper support seat is assembled with the body in the assembly process, this paper analyzes the excessive contact gap between the front suspension support seat and the body, poor positioning angle of the front suspension assembly upper support seat, and the related supporting tools,. Correspondingly’ it is a so proposes an optimization scheme to improve the front suspension tray support tooling and the new front suspension upper support positioning tooling, which ultimately reduces the defect rate.
