ABSTRACT:
An automatic inner diameter measuring apparatus which includes an inner diameter measuring gauge head having at least one contacting element capable of being inserted into bores of an object to be measured and moving in a radial direction of the bore. A stocker is provided which is capable of holding a plurality of inner diameter measuring gauge heads corresponding to different diameters. A three-dimensional moving instrument is provided for detachable coupling with the inner diameter measuring gauge head to facilitate a three-dimensional movement with reference to the object to be measured and the inner diameter measuring gauge. A drive device for the three-dimensional moving instrument is provided. A plurality of master ring gauges supported on a ring gauge support are provided to set an inner diameter measuring gauge head attached thereto to zero.
