在万工显上,被测件圆心与分度台旋转中心同心的快速找正,可用下述调整器。如图所示。千分尺2、3是利用废旧千分尺改制而成,见图(a)。垫板4、5的制做见图(b)。紧固螺钉6、7可利用仪器附件,块规8可选用旧量块,玻璃板9可用透明光板(防止玻璃工作台划伤)。测试方法:使光学分度台1的十字线与测角目镜米字线重合,确定光学分度台旋转中心的仪器读数,将被测件10的基准孔大致放置在 In the million workers were on the test center of the circle and index table rotary center concentric rapid alignment, the following regulator available. as the picture shows. Micrometers 2 and 3 are remodeled using a scrap micrometer, see Figure (a). Shoe plate 4,5 made of Figure (b). Fastening screws 6, 7 can use the instrument accessories, block gauge 8 can use the old measuring block, 9 transparent glass plate (to prevent glass table scratches). Test method: the optical indexing table 1 reticle and angle goggles meter word line coincidence, determine the optical sub-table rotation center instrument readings, the reference hole of the device under test 10 is generally placed in
