Abstract

PURPOSE: To accurately and continuously measure the inside diameter of a multi- step deep hole which is not uniform in the inside diameter and is to be fitted with a turbine rotor or the like, by coupling a measuring unit to a pair of outwardly bent and L-shaped rocking arms with piano wires and determining the displacement of the piano wires.
CONSTITUTION: A cylindrical housing 11 is placed in a measured multi-step deep hole 5 concentrically therewith. A pair of rocking arms 14 are pivoted by an arbor 15 and a block 13 to the tip of housing 11. Very hard and spherical contacting members 16 are supported with rollers 19 on the tips of the outwardly-bent L- shaped parts of the arms 14. Piano wires 20 are coupled to the rollers 19. The piano wires extend from the rollers to a detector 27 along a scale 24. The displacement of the arms 14 is determined from that of the piano wires by a detector 27 to measure the inside diameter of the deep hole.
