Abstract
This utility model discloses a concentricity measuring fixture, relating to the field of measuring device technology. It includes a mandrel, on which two positioning components and a linear bearing are fixedly mounted. An inner diameter dial indicator is fixedly mounted on the linear bearing. The two positioning components are respectively located at both ends of the mandrel, and the linear bearing is located between the two positioning components. The concentricity measuring fixture provided by this utility model can perform concentricity testing on holes requiring concentricity after the machining of large parts, reducing the possibility of shafts being unable to be installed during later assembly.
