POINT-TO-POINT DISTANCE GAUGE, POINT-TO-POINT DISTANCE GAUGE SYSTEM, AND DISTORTION MEASUREMENT METHOD USING POINT-TO-POINT DISTANCE GAUGE SYSTEM

摘要

A point-to-point distance gauge includes a rod-like main body formed by fitting a plurality of cylindrical rods 111, 112, and 113 having different diameters with one another so as to be expandable to a desired length; a spherical-tipped shaft 12 provided on one end 113a of the main body 11 so as to be capable of being folded to a desired angle with respect to the main body 11 and to be capable of maintaining the desired angle, a tip 12a of the spherical-tipped shaft 12 being formed in a spherical shape having a diameter larger than a shaft diameter; and a conical-tipped shaft 13 provided on the other end 113a of the main body 11 so as to be capable of being folded to a desired angle with respect to the main body 11 and to be capable of maintaining the desired angle, a tip 13a of the conical-tipped shaft 13 being formed in a conical shape.
