如图所示,用辅助量块3和标准量块2组成内尺寸标准检定内测千分尺。检定时辅助量块应选择大于10mm 的量块,以免因变形而影响检测结果。外径千分尺1的两工作面顶住精助必块并靠近标准t块一侧。检定内侧千分尺时,使其尽量靠近标 As shown in the figure, the auxiliary gauge block 3 and the standard gauge block 2 are used to form the inner dimension standard test inner micrometer. Assisted the test block should choose the amount of more than 10mm block, so as to avoid deformation and test results. Outer diameter micrometer 1, two work surfaces to withstand the fine will help block and near the standard t block side. When testing the inside micrometer, make it as close as possible to the target
