我厂生产的氮氢气压缩机技术要求高,尤其对气缸、中体.中间接座的同心度、垂直度要求更高。所以对这些主要部件的形位公差要逐件测量,工作量很大。原来这些零件是在一台滚齿机上测量的,既耗电,又很麻烦,且滚齿机不能发挥作用. 后来,我们设计制造了通用性强,可任意调节的同心度垂直度测量工具(见图1)。实践证明:该测量 I plant nitrogen and hydrogen compressor technology requires high, especially on the cylinder, the body. Intermediate seat concentricity, verticality higher. Therefore, the shape of these major components tolerance to be measured piece by piece, a lot of work. Originally, these parts were measured on a gear hobbing machine, consuming both power and trouble, and the hobbing machine did not work. Later, we designed and manufactured a versatile and freely adjustable concentricity measuring tool (see Figure 1 ). Practice shows that the measurement
