Abstract

PURPOSE:To highly precisely and quantatively measure a mutual displacement in center of hole, by the use of a detector, provided with a turning device equipped with a bearing, and of a back plunger type dial gauge attached to the detector. CONSTITUTION:A measuring apparatus is inserted into the holes 2 to be measured, and with an adjusting nut 6 turned, an expansion ring 3 is firmly adhered to the bore of the hole 2 to be measured. Simultaneously, a center rod 5 is automatically set such that the axial center of the rod 5 is positioned concentrically to the center of the hole. A support holder 10 for holding a dial gauge 7 and a bearing-operated rotary device 9 for rotating the support holder 10 are located at a head part of the measurement device, and an indicator 8 for ascertaining orientation is brazed at the rotating device 9. A measurement is conducted in a manner to perform one full turn of the measuring point of the dial gauge in the hole.
