光学分度头一般主要用于角度测量。如果配有相应的附件,如阿贝头等,还可对凸轮轴等其它零件进行测量。但是,我国目前各厂所用的光学分度头,附件不全,测量范围仍然受到限制。为了满足生产需要,我们研制成功三座标测量表架,在光学分度头上装上这个表架后,扩大了光学分度头的测量范围,除能进行角度和分度测量外,还可以对齿轮周节、周节累积误差、斜齿轮轴旋角、滚刀容屑槽导程,容屑槽圆周齿距、前刃面径向性等各项误差进
Optical sub-head is generally mainly used for angle measurement. If equipped with the corresponding accessories, such as Abe, etc., but also on the camshaft and other parts to be measured. However, at present, the optical indexing heads and accessories in our country are still incomplete and the measuring range is still limited. In order to meet the production needs, we developed a successful coordinate measuring table holder, the optical indexing head mounted on the table after the expansion of optical dividing head measuring range, in addition to angular and sub-degree measurement, you can Gear error, the cumulative error of the weeks, helical gear shaft angle, hob chip lead, chip flute circumferential pitch, radial error before the blade surface into
