Device null in order to measure the concentric Characteristic of wa - kupi - su

摘要

A portable, self-contained precision concentricity gauge having a workpiece support portion and gauge support portion mounted on a unitary base plate. The workpiece support portion uses a pair of driven rollers and a moveable idler roller to rotationally support a workpiece. The gauge support portion comprises a gauge carrier which rides on a carrier shaft cantilevered out from the workpiece support portion and adapted for three directions of motion relative to the workpiece. A guide shaft, parallel to the carrier shaft, cooperates with a magnet on the gauge carrier for permitting rotation of the gauge carrier and probe for replacing the workpiece without disturbing the position adjustment of the probe.
