车身覆盖件面品缺陷测量及控制方法

Measuring and Controling Methods of Surface Defects for the Automobile Body Panel

汽车制造过程中,存在着各种缺陷,覆盖件的缺陷会直接影响整车品质,尤其外覆盖件的质量优略,制约着汽车的精细感知及生产成本。外覆盖件的缺陷主要表现在特定的光栅下出现光影扭曲,这是各汽车厂都面临的关键面品问题之一。本文通过专用的测量工具对侧围B柱上部位置的面品缺陷进行深入分析,查找问题出现的主要原因,给出了具体的整改措施,达到了提升冲压件面品品质,降低生产成本的目的。

There are a variety of defects in the automobile manufacturing process, whicn is an direct influence on the quality of vehicle,expecially on the quality-optimization.Moreover, those defects restrict the development of exquisite automobile construction and the manufacturing costs.The defects of the body panels mainly covers light distortion in a particular grating,as is one of the key surface in every automobile factory.This paper says a deep analysis of the surface defects on the upper B-pillar side wall through delicated measuring tools and a discovery of main cause.In addiction, exact corrective measures are given, in order to advance in the surface quality of stamping parts and decrease the costs of manufacturing.
