Abstract

The invention discloses a lever dial indicator read value compensation method, which realizes measurement and reading through the following steps: step 1, fixing a lever dial indicator on a gauge stand, placing both the gauge stand and a plane mirror on a marble platform, and arranging the lever dial indicator over against the plane mirror; step 2, during measurement, enabling the dial indicator and the gauge stand to be not contacted, and moving the plane mirror, so that the pointer and the mirror image of the tested dial indicator are in a mirror surface range at the same time; step 3, shooting images of the pointer of the tested lever dial indicator and the mirror image of the pointer; step 4, measuring the center line height of the pointer of the tested lever dial indicator and the mirror image thereof in the image; step 5, calculating an included angle alpha between the watch hand and the marble platform according to the height measured in the step 4; and step 6, compensating the reading of the lever dial indicator according to the included angle alpha between the pointer and the marble platform to obtain a final measurement reading. The method has the advantages that measurement and reading are convenient, and non-contact measurement can be achieved.

Description

technical field [0001] The invention relates to the field of measuring tools, in particular to a compensation method for the reading value of a lever dial gauge. Background technique [0002] The lever dial gauge is a very important measuring tool used in physics research. When measuring with the lever dial gauge in the prior art, there is a right angle between the stylus and the measured object, so the reading value of the lever dial gauge is the correct value, but this condition is often not satisfied in actual use, and the stylus and the measured object There is an angle α between them, and the correct value of the lever dial indicator at this time = reading amount × compensation coefficient = reading amount × cosα. Because cosα≤1, the reading volume is always greater than or equal to the correct value during measurement. When the measured reading value is small, the amount of error caused by the compensation coefficient cosα is small, which is usually not considered. ...
