某车型前悬架上支撑座与车身装配滑牙缺陷研究及对策

Research&Countermeasures on Slip-tooth Defects of Front Suspension Support Seat and Body Assembly of A Vehicle Type

针对汽车合装工艺中前悬架总成上支撑座与车身合装时出现的螺纹滑牙问题,对前悬架上支撑座与车身接触间隙过大、前悬架总成上支撑座角度定位不良、相关支撑工装存在问题等原因进行分析,针对性提出改进前悬架托盘支撑工装与新作前悬架上支撑定位工装等优化方案,最终降低缺陷率。

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.
