The invention relates to a digital display micrometer which can measure the size of the inner and outer diameter of the zero component. It is characterized by the measurement of the diameter of the inner and outer diameter by the adjustment of the direction adjustment block 6. The two direction adjustment block 6 at both ends of the spring 11 on the moving shaft 8, the direction adjustment block 6 at one end is rotated to the vertical card slot on the side of the moving shaft 8, the other end of the adjustment block is 6 against the end of the tight ruler, then the spring 11 adjusts the block 6 in the direction of the tight ruler, and produces the reverse force to push the direction adjustment within the moving shaft slot. Block 6 and drive the moving shaft 8 to move. The moving shaft 8 and the digital display moving shaft 15 are parallel and synchronous moving. Therefore, the movement value of the movable shaft 7 will be displayed on the digital display device screen of the inner and outer diameters of the digital micrometer. The invention has filled the blank of the domestic related measurement field, and it is not disassembled. The structure design of the measurement of the diameter of the internal and external diameter is also better than the foreign products in the case of the zero components such as the installation of the percentage meter.
【技术实现步骤摘要】
内外径数显千分尺
本专利技术专利涉及一种用来测量零组件内外径尺寸的数显千分尺。
技术介绍
在加工制造业中,精密测量零组件的内外径尺寸时,通常要用内径千分尺和外径千分尺分别测量。在实际的应用中外径千分尺和内径千分尺的测量头直径为8毫米,加上尺身的套筒直径厚度达到15毫米,所以零组件内外径尺寸的高度小于8毫米时是无法进行内外径测量的。因此不同的工厂,企业都会根据不同零件的尺寸要求制作一些专门测量内径或专门测量外径的量具,这些量具的生产周期长,测量精度低,重复利用率低,资源浪费严重等多种因素制约着工厂,企业的生产加工能力发展和利润空间。已知国内目前还没有相关尺寸的测量产品销售。国外具备内外径测量功能的测量尺表是瑞士的Tesainotesa和奥地利品牌英示的产品编号为1197的多功能数显尺,其在实际应用中也存在一些不足:1在测量内径或外径时需要拆卸和安装百分表头等附件,安装过程费时且复杂。2百分表的表针在测量内径和外径时其代表的正负示值会发生变化,经常造成读数的混淆。3不能保证正视百分表读数时,百分表表针与示值就会产生偏离,读的数值就会产生误差影响测量结果。4测量的深度和深度定位面的调节空间小,零组件的测量范围有限。还有重要的一点是进口的测量尺表独占了市场且价格昂贵,我国急需自己的内外径测量器具。
