A drive motor 4 is disposed on the vertical adjuster 3, and a horizontal adjuster 5 is disposed on the output shaft of the drive motor 4. A detector 6 is disposed on the horizontal adjuster 5. When measuring the inner groove of the bearing outer ring, the clamping block 24 clamps the outer side of the bearing outer ring from the outside to the inside, and the detector 6 moves to the inner groove of the bearing outer ring and measures along the inner groove. When measuring the outer groove of the bearing inner ring, the clamping block 24 clamps the inner side of the bearing inner ring from the inside to the outside, and the detector 6 moves to the outer groove of the bearing inner ring and measures along the outer groove.
[0033] When measuring the inner groove of the bearing outer ring, first, the telescopic device 21 is shortened, so that the clamping blocks 24 are at the outermost side of the sliding holes 11, the bearing outer ring is placed between the clamping blocks 24, then the telescopic device 21 is controlled to be lengthened, the connecting rods 23 are driven to rotate, thereby driving the clamping blocks 24 to move from the outside to the inside, since the connecting plate 22 is connected with a plurality of connecting rods 23, the clamping blocks 24 move synchronously, thereby ensuring that the bearing outer ring is moved to the center and clamped.
