Mine image detection patent

Answer: Absolute method can be used to measure the inner hole, universal tool microscope can be used, inflection point method and chord length measurement method can be used for positioning measurement, and image method can also be used for aiming measurement. The relative method can be adopted, and the inductive inner hole comparator and double probes can be used for measurement. The indirect method can measure the inner hole with a three-coordinate machine and the aperture with three-point sampling.

Using absolute method to measure the taper of conical shaft can directly measure the taper of imaging with tool microscope. The mirror image method is adopted, and the line aiming method is used instead of the line pressing method when measuring the length.

Relative method can be measured by laser interference small angle measuring instrument, taper can be measured by sine principle, and white light double beam interference aiming.

The indirect method uses CMM to measure. When measuring, try to select the sections near the two ends of the cone as the measuring sections, measure three coordinates on each section, and then calculate.
