一、问题的提出滚锥是ZX系列振动器的主要零件(见图1),锥体大端有尺寸φ26.8336的要求,且该端距φ17_(+0.002)~(+0.014)径肩之间有285-0.1的长度尺寸要求,这就给测量(工件在机床上顶着)带来了困难。目前大多数厂家是采用锥体定位、悬挂测量法。此法虽能满足精度要求,但用在零件工位测量时,就显得太不 First, the issue put forward Roller cone is the main part of the ZX series vibrator (see Figure 1), the large end of the cone size φ26.8336 requirements, and the end of the pitch φ17 _ (+0.002) ~ (+0.014) shoulder There is a length dimension of 285-0.1 between the requirements, which gives the measurement (workpiece on the machine) is difficult. At present, most manufacturers use cone positioning, suspension measurement. Although this method can meet the accuracy requirements, but when used in the parts station measurement, it appears too
