机械零件位置公差(定向)平行度,各厂都根据零件的结构形状采用不同的方法进行测量;有的依靠夹具的精度来保证,根本不进行测量;在机械设备使用之后的鉴定及修复加工中更是很少进行测量。这样常常造成零件不合格,不能进行装配,或勉强装配之后影响机械设备的使用性能。为了解决这个测量问题,这里介绍一种简易的测量方法,其测量工具制做简单,测量也方便,不用平台可以在现场将零件放在任意 Mechanical parts position tolerance (orientation) parallelism, each factory according to the shape of the parts using different methods of measurement; some rely on the accuracy of the fixture to ensure that no measurement at all; after the use of machinery and equipment identification and repair processing It is rarely measured. This often results in defective parts, inability to assemble, or unfavorable effects on the performance of mechanical equipment after barely assembling. In order to solve this measurement problem, a simple measurement method is introduced here. The measurement tool is simple to make and the measurement is also convenient. Without the platform, parts can be placed on the spot.
