轻卡车前风窗玻璃装配质量影响因素分析

Analysis Of Influencing Factors On The Assembly Quality Of Front Window Glass Of Light Truck

汽车白车身前风窗由前围焊接总成、左右侧围总成、顶盖焊接总成、前顶横梁等多个零部件搭接、拼焊而成。它组成复杂,所以尺寸容易出现问题。文章对一款轻卡车前风窗玻璃装配困难的现象展开分析,通过三坐标检测数据、前风窗检具复检等进行综合对比,确定质量改善方向。最终把前风窗开口尺寸控制在公差范围内,满足装配要求,从而改善了整车质量。

The front window of the body-in-white of a car is made by overlapping and welding multiple components such as a firewall welding assembly,body side L/R assembly,a roof welding assembly,and a front roof beam.Its composition is complicated,so the problem of size is easy to occur.This article analyzes the difficult assembly of the front windshield glass of a light truck.Through comprehensive comparison of three-dimensional inspection data,re-inspection of the front windshield inspection fixture,etc.,the quality improvement direction is determined.Finally,the size of the front window opening is controlled within the tolerance range to meet the assembly requirements,thereby improving the quality of the vehicle.
