内圆锥体大端直径及外圆锥体某一截面直径的测量,无论用卡尺、样板、塞规或其它量具,其测量精度低,使用不便;特别是加工过程中随机测量尤为困难。在我厂生产的产品中,具有这样形状的零件(如图1)品种多、批量大。由于这类零件需要测量的部件都处于零件内孔深处或某一理论位置上,尺寸精度较高。为了准确测出这些尺寸,我们设计、制造了如图2所示的量具。
Large diameter of the inner cone and the outer cone of a cross-sectional diameter measurement, whether with calipers, templates, plug gauges or other measuring instruments, the measurement accuracy is low, the use of inconvenience; in particular, the process of random measurement is particularly difficult. In my factory production of products, with such a shape of the parts (Figure 1) Variety and large quantities. Because such parts need to measure the components are in the hole depth or a theoretical position, the higher dimensional accuracy. In order to accurately measure these dimensions, we designed and manufactured the gauges shown in Figure 2.
