歪による測定誤差の発生を確実に防止できろ効果がある
。In addition, the three gauge heads were attached to the flange of the spindle with three string-like bodies, and the end of the spindle on the gauge head side was supported by the second support body, so each gauge head was attached in the radial direction. Even if a bending moment is applied to the spindle due to variations in the spring force of the three springs, the second support can prevent large bending distortions from occurring in the spindle, and as a result, measurement errors due to spindle distortion can be reduced. It is effective if it can reliably prevent its occurrence.
しかもスピンドルの両端を摺動自在に保持させているの
で スピンドルがガタつくようなことばない。Moreover, since both ends of the spindle are held slidably, there is no chance of the spindle shaking.
従って誤差の少ない測定をすることができろ。Therefore, it is possible to perform measurements with less error.
更にスピンドルに設けたフランジに上記各ピンを進退調

整することができる。Furthermore, since each of the pins mentioned above is attached to the flange provided on the spindle so that they can be adjusted forward and backward, when manufacturing the inside measuring device, it is possible to avoid errors in the length of the string and its installation, or minute errors in the installation position of the pulley. Even if an error occurs in the amount of protrusion of the contact point, the amount of protrusion of the contact point can be adjusted satisfactorily by adjusting the forward and backward movement of the pin.
特に三点式の内側測定機においては、各測定子間の突出
量の誤差を簡易に調整できるので、製作が容易である。In particular, a three-point inner measuring device is easy to manufacture because the error in the amount of protrusion between each probe can be easily adjusted.
