Background
In actual use, the common measurement range of the internal measurement percentage ruler is phi 5 mm-phi 75mm, the common measurement range of the three-jaw inside micrometer is phi 6 mm-phi 100mm, the common measurement range of the inside dial indicator is phi 10-phi 450mm, and the common measurement range of the inside percentage ruler is phi 50-phi 5000mm, so that the inside diameter of the large hole with the diameter more than phi 450mm can be measured only by using the inside percentage ruler in the production and quality inspection processes.
The following disadvantages exist in the measurement of the large hole:
(1) When the inside diameter percentage is measured, the outside diameter micrometer is used to adjust the size to be measured, then the inside diameter percentage is put into the diameter direction of the measured inner hole, the measuring surface of the micrometer is supported on the measured surface, the measuring surface on one side of the differential cylinder swings in the radial section of the hole, the differential cylinder is adjusted, and the measured size can be calculated by reading the numerical value of the differential cylinder after the percentage is taken out.
