The three groups of electric push rods 14 work synchronously. The controller 3 controls the work of the three groups of electric push rods 14 and the electric telescopic rod 10. Before use, the bearing body 4 is placed on the test bench 1. The three groups of electric push rods 14 work synchronously to drive the arc positioning plate 15 to move, so that the three groups of arc positioning plates 15 are all attached to the outer wall of the bearing body 4 to fix the position of the bearing body 4. Then, through the work of the electric telescopic rod 10, the inner diameter micrometer 12 is extended into the inner ring of the bearing body 4. By observing the inner diameter, the inner diameter of the inner micrometer 12 is measured. The scale of the inner diameter micrometer 12 can obtain the size of the bearing body 4. The rotation of the hand wheel 6 can drive the driving pinion 5 to rotate. Since the driving pinion 5 is meshed and connected with the driven large gear 7, and the driven large gear 7 is fixedly connected with the rotating rod 8, the mounting plate 9 and the electric telescopic rod 10 are driven to rotate. The position of the bottom inner diameter micrometer 12 can be adjusted.
