内径百分表在企业生产实际中,被广泛应用于机械加工和设备维修的内尺寸的测量,然而在实际的测量中,有些操作者往往不是很清楚内径百分表的结构、工作原理,操作不规范,从而给测量结果带来了一定的误差。针对以上情况本文对内径百分表的结构原理、使用规范作了进一步研究,从而达到准确测量的目的。 Inner diameter dial indicator in the actual production, is widely used in machining and equipment maintenance of the internal dimensions of the measurement, but in the actual measurement, some operators are often not very clear diameter dial indicator structure, working principle, operation Non-standard, which gives the measurement results brought some error. In view of the above situation in this paper, the structure of the inner diameter dial indicator, the use of norms made further study, so as to achieve the purpose of accurate measurement.
