Jig and method for measuring flange distortion using portable non-contact three-dimensional coordinate measuring device

摘要

PROBLEM TO BE SOLVED: To provide a measuring method capable of measuring not only data of winding but also data of inclination of a flange face, the method having a little space required for measurement and without reduction in measurement accuracy even in a site where vibration occurs, in distortion measurement of the flange face of a heat exchanger.SOLUTION: When performing flange distortion measurement by using a portable non-contact three-dimensional coordinate measuring apparatus, in order to install a target seal 6 inside a flange, measurement is performed by using a flange distortion measurement jig capable of installing the target seal inside the flange while the target seal is installed on a plate in advance.SELECTED DRAWING: Figure 5
