The invention discloses an inner ring assembly position measuring tool, which comprises a base, a support ring and a positioning ring. The base is circular in shape. The upper surface of the base is provided with a loop of support ring bolt holes around the circle center. The support ring is fixedly arranged on the base through bolts. The edge of the upper surface of the base is provided with a loop of positioning ring bolt holes. The positioning ring is fixedly arranged on the base through bolts. A plurality of bush holes are circumferentially distributed in the support ring. Each bush hole is provided with a bush. The measuring tool is provided with a plurality of circumferential long-waist grooves in the circumference direction, and the circumferential length of each groove is designedto be able to measure an adjacent hole site of a measured radial hole just after the measuring tool rotates for a certain distance, thereby ensuring strength of the positioning ring, realizing halvingof the number of detectio
