在机械加工生产中以加工孔(轴)类型的零(部)件为最多。在批量生产中如果孔(轴)径要求不太精密时用量规来检验是很好的方法。但是往往由于量规的几何形状不合理而给检验工作带来不少麻烦和误检。 用量规检验孔(轴)径是否合格是依据孔(轴)径的极限尺寸来判断的。而孔(轴)径的最大极限尺寸和最小极限尺寸又是依据孔(轴)的综合功能要求来确定的。所以量规的尺寸和几何形状必须依据孔 In the production of machining in the hole (shaft) type of zero (parts) for the most. In the mass production hole (shaft) diameter requirements are not very precise when using gauge to test is a good method. However, due to the irregular geometry of the gauge, a lot of trouble and misdetection are brought to the inspection work. Gauge test hole (shaft) diameter is qualified according to hole (shaft) diameter to determine the size of the limit. And hole (shaft) diameter maximum limit size and minimum limit size is based on the hole (shaft) of the integrated functional requirements to determine. So the gauge’s size and geometry must be based on the hole
