小型孔类零件工序间同轴度误差的快速检测

Quick test of coaxiality error of small-hole parts between processes

目前用于工件内孔同轴度工序间测量方法很多,但用于小型孔类零件检测时结构上较难实现,使用也不太方便。为此,研制了两种很有特色的同轴度快速检测装置,其检具的测量精度保证了检测结果的准确性。

There are many methods for measuring the coaxlality of work piece inner holes between processes, which are inconvenient for small-hole parts. Two quick test devices have been developed, the measuring accuracy of the test tool supports the correction of the test results.
