INNER DIAMETER MEASURING APPARATUS FOR EASY MEASUREMENT OF INNER DIAMETER, ERROR RATE, CIRCULARITY AND SQUARENESS OF AN OBJECT

摘要

PURPOSE: An inner diameter measuring apparatus is provided to support an object secured on an inclined measurement plate stably using a stator and measure the inner diameter of the object using a measurer moving back and forth along a measurer assembly.;CONSTITUTION: An inner diameter measuring apparatus comprises a base(10) with a through hole, a measurement plate which is installed at an angle on the base to place an object thereon and has a guide slit, a stator(50) which secures the object in place by contacting with the inner circumference of one side of the object while exposed through the guide slit, and a measurer assembly(70) including a measurer which measures the inner diameter of the object by contacting with the inner circumference of the other side of the object.;COPYRIGHT KIPO 2010
