1 设计目的 随着生产的发展,产品质量更加成为企业的生命线。工具处制造的模具、工夹具、刀量具、专用组合机床制造的质量,直接反映到工厂产品质量上。要保证产品质量,一定要抓好工装的实物测量。例如,加工柴油机机体主轴承孔的镗夹具中的高精度旋转套零件,其外径为φ310mm,而其尺寸精度,同轴度、圆度、配合间隙都要求在0.005mm以内。原来的辅助量规,即T型槽镶配的升
1 Design Purpose With the development of production, product quality has become the lifeline of enterprises. Tools manufactured at the mold, jig, measuring tools, special combination of machine tool manufacturing quality, directly reflected in the factory product quality. To ensure product quality, we must do a good job in-kind measurement of tooling. For example, the processing of diesel engine main bearing bore boring fixture of high-precision rotating sleeve parts, the outer diameter of φ310mm, and its dimensional accuracy, coaxiality, roundness, with clearance requirements are within 0.005mm. The original auxiliary gauges, that is, T-slot fitted with l
