过去对于箱体孔的中心高测量,一般多采用标准心轴法,这种方法有许多弊端,因为其加工要求主要是孔中心高,并非孔径(孔径另有要求),因此,由于孔径有公差,标准样棒有公差,再加上检测量具的本身误差,这样综合误差就大了,测量精度不易保证。对于不同的孔径还需要有不同的标准样棒,通用性差,工序繁琐。图1所示是我设计制作的中心高游标卡尺,不同孔径的中心高都可直接测量读出,可
In the past for the center of the box hole high measurement, the general use of standard mandrel method, this method has many drawbacks, because its processing requirements are mainly hole center height, not the aperture (aperture required), therefore, due to the aperture tolerance , Standard rod with tolerances, plus the error of the measuring gauges themselves, so that the integrated error is large, the measurement accuracy is not easy to guarantee. For different aperture also need to have a different standard sample stick, poor versatility, process cumbersome. Figure 1 shows the center of my design and manufacture of high caliper, the center of different aperture height can be measured directly read,
