本文介绍了一种用于分度检查的精密测微定位器的结构和使用方法。这种新型仪器可弥补现有分度测量装置的不足。——编者分度检查始终是一项重要的测量任务。齿轮、分度盘、量规和工件的角分度,或齿条、丝杆以及其它工件的直线分度都需要进行检查。为此,人们常常采用一般的测量工具,如分度头、分角测量仪器或具有平行光管的经纬 This article describes the structure and use of a precision micrometric locator for indexing inspection. This new type of instrument can make up for the deficiencies of the existing indexing device. - Editor’s indexing inspection is always an important measurement task. Gears, dials, gauges, and workpiece angular indexing, or rack, screw and other workpiece linear indexing need to be checked. To this end, people often use the general measurement tools, such as indexing head, angle measurement instruments or with parallel light tube latitude and longitude
