Center-to-center distance variation measuring device

摘要

PROBLEM TO BE SOLVED: To measure a change in a center distance with high accuracy for a structural body, consisting of two interlocked components.;SOLUTION: A measuring assembly for change in the center distance which can measure the change of center distance of a structural body, in which a component part 1 with the center of a measurement hole 1a and a component part 2 with the center of component part hole 2a interlocked each other at a predetermined center distance, includes a pressurization mechanism which includes a cam 13 pressurizing the structural body along the center distance, in both the forward and backward directions; the reference pin 4 of fixed side inserted into the component part hole 2a with the center of fixed side in both the measuring hole 1a and the component part hole 2a of the structural body; the measuring pin 5 inserted into the measuring hole 1a with the center of varying side of the aforementioned structural body following the change of measuring hole 1a; and a displacement gage 6 measuring the change of center distance from the position of each point of the measuring pin 5 in pressurization states in both the forward and backward directions.;COPYRIGHT: (C)2005,JPO&NCIPI
