摘要
根据公差中心尺寸控制原理,研究了移动公差设定技术。结合车身具体部位,通过设定移动公差,解决了零件在匹配过程中的干涉现象,避免了修正模具及实际生产中强行装焊的问题。
According to the principle of the tolerance central dimension control,it has researched the technology of the processing excursion tolerance. Based on the specific parts of the vehicle ,we have solved the phenomenon of interference between parts ,avoided the problems of the mold amendment and welding assembly in the actual production by setting the processing excursion tolerance.
