车身尺寸工程中的偏移公差设置

Excursion Tolerance Allocation of Vehicle Dimension Engineering

零部件公差分配是车身尺寸工程中一项重要的环节,偏移公差是公差分配的一种特殊形式。文章采用具体实例,阐述了在开发设计阶段根据车身结构特征在零件某些特殊部位设置偏移公差,能有效解决零件匹配过程中的干涉、定位不稳等问题,减少模具更改次数,缩短开发周期。

Part tolerance allocation is one of the most important procedures of the vehicle dimension engineering. Excursion tolerance is a special type. The article uses concrete examples to illustrate the allocation of excursion tolerance of the particular component during the design phase. This will resolve the interference and instability of assembling process which will reduce the modifying of the tools and shorten the development cycle.
