Abstract: front page image
(EN)A measuring device (10) capable of providing the inner diameter, straightness, and cylindricity of a hole (WA), wherein a variation in back pressure of gas injected into the hole (WA) is detected by a transducer (30), reflected light from a reflective member (18) installed on a ball (14) is received by a light receiving part (22), and a variation in peak position (A) of received light amount is obtained when the ball (14) inserted in the hole (WA) in a work (W) is moved in the longitudinal direction of the hole (WA) in an automatically centered state, whereby the inexpensive measuring device (10) for measuring, in the state of no-contact with the work, the inner diameter, straightness, and cylindricity of the hole (WA) can be provided.
(FR)L'invention concerne un appareil de mesure (10) permettant de fournir le diamètre, la rectitude et la cylindricité d'un trou (WA). Une variation de la contrepression du gaz injecté dans le trou (WA) est détectée par un transducteur (30), la lumière réfléchie par un élément réfléchissant (18) installé sur une bille (14) est reçue par un élément (22) photorécepteur, et on fait varier la position de crête (A) de la quantité de lumière reçue en déplaçant la bille (14), insérée dans le trou (WA) d'une pièce (W), dans le sens longitudinal du trou (WA) de manière automatiquement centrée. Cet appareil de mesure (10) peu coûteux sert à mesurer sans contact le diamètre interne, la rectitude et la cylindricité d'un trou (WA).
(JA) ワークWの孔WAに挿入されたボール14が自動求心された状態で孔WAの長手方向に移動されたときの、孔WAに噴射された気体の背圧の変化を変換器30で検出するとともに、ボール14に設けられた反射部材18からの反射光を受光部22で受け、受光量のピーク位置Aの変化を求めることによって孔WAの内径、真直度、及び円筒度を求めるように構成したので、非接触で安価な孔WAの内径、真直度、及び円筒度を測定する測定装置10を得ることができる。
