Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 管穴の深浅にかかわらず管穴内径を精度良く 計測することができ、また管穴内径の自動計測を可能に する管穴内径計測プローブを提供する。 【解決手段】 プローブ本体31の長手方向4箇所には 軸芯調節手段としてフロントスタビライザ2,4、テン ショナー10及びスプリングプランジャー13を備え、 プローブ本体31の中央部には管穴内径計測手段として 歪板6A,6Bとこれらの歪板6A,6Bに取り付けた 歪ゲージとを備えた。また、歪板6A,6Bの両端部に は小形玉軸受9A,9Bを備えた。更に、プローブ本体 31の基端部では、リアサポート12の端部をプラグホ ルダ14の端部に遊嵌させると共に、リアサポート12 の端部の外周の4箇所に螺合させたねじ22の頭部(突 部)を、プラグホルダ14の端部の周方向4箇所に形成 した穴14bに各々遊嵌させて、リアサポート12とプ ラグホルダ14とを結合した。 PROBLEM TO BE SOLVED: To provide a borehole inner diameter measuring probe capable of accurately measuring the borehole inner diameter regardless of the depth of the borehole and enabling automatic measurement of the borehole inner diameter. SOLUTION: At four positions in a longitudinal direction of a probe body 31, front stabilizers 2, 4, a tensioner 10, and a spring plunger 13 are provided as axial center adjusting means, At the center of the probe main body 31, strain plates 6A and 6B and strain gauges attached to these strain plates 6A and 6B were provided as tube hole inner diameter measuring means. Also, small ball bearings 9A, 9B were provided at both ends of the strain plates 6A, 6B. Further, at the base end of the probe main body 31, the end of the rear support 12 is loosely fitted to the end of the plug holder 14, and the rear support 12 The heads (protrusions) of the screws 22 screwed to four places on the outer periphery of the end of the plug holder 14 are respectively loosely fitted into holes 14 b formed at four places in the circumferential direction of the end of the plug holder 14. And the plug holder 14 were connected.
