Detection device for driving shaft outer ball cage

The utility model discloses a detection device used for a driving shaft outer ball cage, comprising a driving member and a first clamp, the output end of the driving member is connected with the first clamp and is used for outputting torque to the first clamp, the first clamp is used for fixing a locking nut, the outer side of the locking nut is sleeved with a hub bearing, and the hub bearing is connected with the driving member. The second clamp is used for fixing a standard sample piece of the outer ball cage, the outer ball cage is matched with the locking nut through a spline, and the detection unit is suitable for obtaining stress between the outer ball cage and the press-fitting end face of the hub bearing when the outer ball cage is matched with the locking nut in a threaded mode. The detection device for the outer ball cage of the driving shaft can detect the torque when the outer ball cage and the press-fitting end face of the hub bearing are attached in place, so as to identify whether the designed
