用图中所示的内径千分表大量测量零件内部尺寸时,在精度和生产率方面都能获得良好效果。 在底座1上装有立柱,用螺钉14把经过淬火和磨削的套9拧到立柱上,而套的外径同被检孔的尺寸作紧转配合。 在套筒内装千分表6的夹持器5,用夹头15把千分表夹持住。夹持器本身则用四小螺钉8和10 With the internal diameter dial gauge shown in a large number of parts internal dimensions, the accuracy and productivity can get good results. A pedestal is mounted on the base 1, and the quenched and ground sleeve 9 is screwed to the upright by a screw 14, and the outer diameter of the sleeve is tightly matched with the size of the hole to be inspected. Hold the holder 5 of the dial gauge 6 in the sleeve and hold the dial gauge with the chuck 15. The holder itself uses four screws 8 and 10
