Comprehensive measuring device for inner ring

The utility model relates to the technical field of bearing clearance measurement, in particular to an inner ring comprehensive measurement device which comprises a fixed upper die, an inner ring which can move up and down and is in contact with the bottom end of the fixed upper die is arranged at the bottom end of the fixed upper die, and a position sensor used for comprehensively measuring the inner ring is arranged above the fixed upper die. According to the inner ring comprehensive measurement device, through the arrangement of the structure, manual axial clearance detection can be replaced, certain impact caused by loading of the upper end of the inner ring due to gestures, weight and speed relations of people is avoided, instability caused by manual axial clearance detection is avoided, and the detection accuracy is improved. And the problem that only the axial clearance of a certain point in the bearing is relatively measured and the influence of the groove position parallel difference on the axial cle
