摘　　要：汽车主模型检具是专门用来验证汽车覆盖件匹配的一种特殊工装,且由许多模块组成。由于模块材料为超硬铝,且常为大型薄壁件,所以在加工时极易变形,加工质量难以保证。针对大型薄壁件在加工中采用的装夹方式、机床和刀具的选择以及对加工工艺路线制定等方面进行研究,并提出一些预防加工变形的措施。最后,通过对车门模块精加工进行验证,用三坐标测量机对其薄壁处若干点进行测量,所有变形量均控制在0.1 mm以内。Master model fixture is a kind of special equipment which is used to check the assembly of automotive panels. Because master model is usually made of many blocks which have many large thin-wall edges and are made from superduralumin, deformation often occurs during its production and its quality is hard to control. The clamping, machine tools, cutting tools and processing route during large thinwall parts processing were studied. Some measures were put forward to provent manufacturing deformation. Finally, the research was verified through final-manufacturing of door block. All deformation of thin-wall edges was measured by CMM, which is controlled within0. 1mm.
