孔傾斜計測治具及び孔傾斜計測方法

Tool and method for measuring hole inclination

Abstract

【課題】計測対象孔の近傍に障害物がある場合であっても、信頼性の高い計測結果が得られる孔傾斜計測治具及び孔傾斜計測方法を提供する。 【解決手段】管孔加工面Wbに形成された管孔Waに挿入された状態でその中心軸線1a周りに回転可能なロッド部1と、ロッド部1に設けられ、中心軸線1aが延びる軸方向と直交する直交方向に延在するアーム部2と、アーム部2において上記直交方向に間隔をあけて設けられ、中心軸線1a周りにおける第1の位置にアーム部2が位置するときと、該中心軸線1a周りにおける上記第1の位置と異なる第2の位置にアーム部2が位置するときとの、管孔加工面Wbに対する上記軸方向における相対距離の変化を計測可能な複数の計測部3と、を有する孔傾斜計測治具A及び当該孔傾斜計測治具Aを用いた孔傾斜計測方法を採用する。 【選択図】図1
PROBLEM TO BE SOLVED: To provide a hole inclination measuring tool and a hole inclination measuring method capable of obtaining a highly reliable measurement result even when an obstacle exists in the vicinity of a measuring target hole.SOLUTION: A hole inclination measuring tool A includes: a rod part 1 allowed to be rotated around a center axis line 1a in a state of being inserted into a tube hole Wa formed in a tube hole working surface Wb; an arm part 2 formed on the rod part 1 and extended in an orthogonal direction orthogonal to an axis direction in which the center axis line 1a is extended; and a plurality of measurement parts 3 attached to the arm part 2 with an interval in the orthogonal direction and capable of measuring changes of relative distances from the tube hole working surface Wb in the axis direction when the arm part 2 is located on a first position around the center axis line 1a and when the arm part 2 is located on a second position different from the first position around the center axis line 1a. The hole inclination measuring method using the hole inclination measuring tool A is adopted.
