我厂在检验工件深度的尺寸公差时,曾学习捷克的先进经验,用千分表来测量,得到很好的结果。它的构造如附图,共有八个零件,1是千分表,2是制紧螺钉,3是弹簧,4是有尾螺钉,5是量规芯子,6是开口套,7是量规体,8是标准块。标准块的高度尺寸和被测量的工件名义尺寸做得一样,材料用y19A高级碳钢制成,淬火寸稳硬度是Rc60～65,为了使标准块的尺定,应经过时化处理,在它测面处用电笔刻出其实际尺寸,以备换算。使用的方法:将标准块放在平板上,量规体端面平稳地靠紧标准块上,
When inspecting the dimensional tolerance of the depth of the workpiece, our factory has learned the advanced experience of the Czech Republic and measured it with a dial indicator to obtain good results. Its structure is shown in the accompanying drawings, there are eight parts, 1 is a dial indicator, 2 is a tightening screw, 3 is a spring, 4 is a tail screw, 5 is a gauge core, 6 is an open sleeve, 7 is a gauge body, 8 is the standard block. The height of the standard block is the same as the nominal size of the workpiece. The material is made of Y19A high-grade carbon steel and the quenching hardness is Rc60 ~ 65. In order to make the standard block size, it should be processed in time The surface of the pen at the actual size of the carved, ready for conversion. Method of use: Place the standard block on the flat plate, the end of the gauge body is steady against the standard block,
