公差带投影仪是大批大量生产过程中,检验零件直径、高度、深度、锥度、螺纹、盲孔等效率很高的仪器。它比通用量具检验效率能提高几倍到几十倍。如与精巧设计的检验卡具结合使用,还能扩大量具的检验范围,充分发挥这种仪器的检验效用。下面介绍几种测量卡具的图例,供参考。一、盲孔直径与深度的测量卡具:盲孔直径及深度在普通投影仪上很难测量,但在公差带投影仪上配合图1、图2所示的卡具,测量则十分简易,效率很高。
Tolerance with the projector is a large number of mass production process, testing parts diameter, height, depth, taper, thread, blind hole and other high efficiency instruments. It is several times better than the universal measuring tool to improve the efficiency of several times. If used in conjunction with the sophisticated design of the test fixture, but also to expand the scope of measuring instruments, give full play to the test of this instrument utility. Here are some illustrations of the measuring fixture, for reference. First, the blind hole diameter and depth of the measuring fixture: blind hole diameter and depth of the projector is difficult to measure in ordinary, but with tolerance projector with Figure 1, Figure 2 shows the fixture, the measurement is very simple, high efficiency.
