在机械制造中,垂直度是一项十分重要的技术要求,因此准确地测出垂直度是测试工作的重要课题。通常垂直度的检查采用直角尺目测,或用塞尺测量间隙的方法。而直角尺的检定则采用三个直角尺在平板上互检或用标准角尺检定,也可用角尺检查仪直接进行检定,后者必须具备这样的设备条件才行。我厂计量室在日常工作中,经常检定直角尺,测量带有垂直度要求的专用量具。过去,我们用零级或一级直角尺以间隙法测量,但测量结果不太准确。后来我们在学习了兄弟单位的先进经验的基础上,自制了一个能够读数的测量垂直度的检查器,使用效果很好,经检
In machinery manufacturing, the verticality is a very important technical requirement, so accurately measure the verticality is an important task of the test. Usually verticality inspection using square foot visual inspection, or measure the gap with a feeler. The square ruler of the test is the use of three square ruler in the flat on each other or test with a standard square ruler, square gauges can also be used directly for testing, which must have such equipment Caixing. I plant measurement room in daily work, often test the right-angle ruler, measuring the vertical with the requirements of the special measuring tools. In the past, we used the zero-order or first-order square to measure the gap method, but the measurement was not accurate. Later, on the basis of studying the advanced experience of our brother unit, we made a self-made checker that can measure the verticality of the readings, and the result is very good.
