微型轴承(内径≤10mm)内径和外圈滚道尺寸的测量,一般均在卧式测长仪上采取直接测量法或投影法进行测量。这种测量方法操作麻烦,同一工件经多次测量同一部位尺寸,其测值仍不稳定,误差较大。为了充分利用卧式测长仪标准刻尺,我设计制造出如图所示小测钩。将这样两个小测钩安 Miniature bearings (diameter ≤ 10mm) diameter and outer ring raceway size measurement, are generally measured in the horizontal length measuring instrument to take direct measurement or projection method for measurement. This kind of measurement method is troublesome to operate. The same part size is measured by the same workpiece several times, and the measurement value is still not stable and the error is large. In order to make full use of the horizontal length gauge standard ruler, I designed and manufactured a small measuring hook as shown. Will be such a small test hook
