目前在分度及一些角度的测定上都采用光学分度 头,但是在目前情况下一般中小型工厂并没有光学分度 头,而且对光学分度头的使用率亦很低。若为解决这样的分度问题,要配置光学分度头是不经济的、我厂针对 这种情况采用下面的装置。 这一装置是将光学象限仪,利用如图1的附件,装 在 At present, optical indexing heads are used for indexing and measurement of some angles. However, in the current situation, small and medium sized factories generally do not have optical indexing heads, and the use rate of optical indexing heads is also very low. To solve such an indexing problem, it is uneconomical to configure an optical indexing head, and the factory uses the following device for this situation. This device is the optical quadrant instrument, the attachment shown in Figure 1, installed
