功能尺寸在内外饰零件上的应用

The Application of Fucntion Dimension on Interior and Exterior Parts

综合介绍了尺寸控制中的功能尺寸工具,这些工具原来主要应用于车身零件的尺寸控制上,它们在内外饰外购件上的应用,可对外购件在装配中的重点距离、位置度等元素进行直接评价和监控,从而有效提升整车匹配环节的尺寸分析工作效率,提高尺寸匹配质量,提升整车装配调整工艺效率。基于某主机厂开展项目案例,详细介绍了内外饰零件中应用的功能尺寸类别、功能尺寸体系流程建立的详细步骤,并针对某车型的后保险杠零件,介绍了功能尺寸具体定义范围、尺寸公差建立等技术内容,为内外饰零件的尺寸控制工作提供了有效的范例,为整车匹配质量提升提供了新的尺寸分析和评价手段,具备一定的推广应用效益。

This paper introduces the function dimension tool of dimension controlling work,which is used in body parts dimension controlling.The application of function dimension on interior and exterior parts can evaluate and monitor the influence dimension elements in assembling process,such as distance,location and so on.,to increase effiency of analysis and assembling.According to some project in car plant,the paper introduce the types of dimension controlling,process of building system.Based on the rear bumper case,the way of the area and tolerance definition can be a effective and extended process for dimension engineering,offer a new way for the car dimension matching quality.
