在航空科研生产中,经常碰到一些浅直口尺寸,精度要求高的零件,用常规量具无法测量,我们制作了如图示测具,效果较好。这种测具主要由测头、基准板、测杆、测杆座四个部件组成,它是利用杠杆原理来进行测量的,测头1和测杆座8可以在基准板上来回滑动,调整所需要的测量尺寸,靠螺钉11固定在基准板2上。测量方法:先将测头固定在基准板2的一定位置上,再在基准板2上滑动测杆座8,用卡尺量得所需测的大致尺寸,再固定测杆座8,利用千分尺
In the aviation scientific research and production, we often encounter some shallow straight mouth size, high precision parts, with conventional measuring tools can not measure, we have produced the illustrated measuring tools, the effect is better. This test mainly by the probe, the reference plate, measuring rod, rod base four components, it is the use of lever principle to measure, probe 1 and rod base 8 can slide back and forth on the reference plate, adjust The required measuring dimensions are fixed on the reference plate 2 by screws 11. Measuring method: first probe fixed to a certain position on the reference plate 2, and then slide the rod base 8 on the reference plate 2, measured with the caliper required to measure the approximate size, and then fixed pole seat 8, the use of micrometer
