Abstract
The utility model discloses a jig for measurement of a clamping shaft. The jig is more stable when matched with a flat plate and a reading device to conduct pulsation measurement. The jig comprises a locating seat. A locating hole used for passing of the shaft is arranged on the locating seat. A radial hole communicated with the locating hole is arranged in the radial direction of the locating hole. One end of the radial hole is provided with a contraction hole, and the other end of the radial hole is provided with a threaded hole. An elastic compressing device formed by a compressing piece and a pressure adjusting device is arranged in the radial hole. The compressing piece is a metal ball or a rubber bar which is bound by the contraction hole in the single direction. The pressure adjusting device is a pressure adjusting nut connected with the threaded hole through threads and acts on the compressing piece along the axial direction of the radial hole to enable the compressing piece to contact with the shaft in rolling mode. According to the jig, the pressure adjusting device is used to change the position of the compressing piece and control the magnitude of compressing force so that a part can not be damaged by scratching or pressing due to over large pressure, and unstable measurement can not be caused by over little pressure, and therefore the jig can adapt to changes of radial gaps of a workpiece, is simple and reliable in operation, and is mainly applied to radial pulsation measurement.
