The working principle of the present invention is described below: the bearing mode to be detected is in the discharge groove 12, the bearing 4 with the detection rolls from high to low in the discharge groove 12 under the action of self weight, the bearings to be detected in the discharge groove 12 are arranged in a bearing row in a front-back mode, as shown in fig. 3, the bearing 4 to be detected positioned at the foremost side of the bearing row is in contact with the blocking release part 2, and the bearing row is blocked. The driving gear 23 is driven to rotate to drive the driven gear 22 to rotate, and then the driving gear 21 is driven to rotate, at the moment, the driving gear 21 drives the blocking release part 2 to rotate, as shown in fig. 4 and 5, along with the rotation of the blocking release part 2, the blocking release part 2 gradually rotates until the opening of the blocking release part 2 faces the bearing row, as shown in fig. 6, at the moment, the bearing 4 to be detected on the foremost side of the bearing row is released to roll to the inner side of the blocking release part 2; as fig. 7 shows, with continued rotation of the blocking release 2, the blocking release 2 again blocks the bearing train, and the released bearing 4 to be tested rolls out of the blocking release 2 through the opening of the blocking release 2. When the bearing 4 to be detected rolls to the position of the notch 13, the released bearing 4 to be detected in each discharge groove 12 is clamped in the material stopping hole 14. Then the clamping unit acts, and the brackets 31 positioned at the front side and the rear side of the material channel 1 move to the side close to the material channel 1; in the process, the clamping mechanism on the front side bracket 31 extends into a plurality of inner rings of the bearing 4 to be detected in the front end discharge groove 12, and the clamping mechanism on the rear side bracket 31 extends into a plurality of inner rings of the bearing 4 to be detected in the rear end discharge groove 12. Then the clamping driving mechanism acts to expand the clamping rod 36 to the outside, and the inner ring of the bearing 4 to be detected is supported in a three-point contact mode. After the clamping mechanism extends into the inner ring of the bearing 4 to be detected, the clamping mechanism is deviated to the middle upper part of the inner ring of the bearing 4 to be detected, and at the moment, after the plurality of clamping rods 36 expand outwards, the bearing 4 to be detected is clamped, and the bearing 4 to be detected is lifted, so that the bottom of the bearing 4 to be detected is away from the material stopping hole 14. After the bearing 4 to be detected is lifted, the outer ring 41 of the bearing 4 to be detected is contacted with a detection wheel 52 of the detection unit; at this time, the lifting cylinder 8 is driven to move, so that the friction wheel 82 is lifted to contact with the outer wall of the outer ring 41, and then the rotation of the friction wheel 82 is driven by the rotating motor 83, and the friction wheel 82 rotates to drive the rotation of the outer ring 41. When the outer ring 41 rotates, the detection wheel 52 rolls along the outer wall of the outer ring 41, and when the outer ring moves in the radial direction, the detection wheel 52 moves up and down while rotating. In the process that the detection wheel 52 moves up and down, the driving end 512 of the detection rod 51 is always in contact with the contact part 551 of the swing rod 55, so that the up and down movement of the detection rod 51 drives the swing rod 55 to swing up and down in the vertical plane. The swing link 55 is hinged to the housing 5 by the hinge shaft 56, and since the distance between the contact portion 551 of the swing link 55 and the hinge shaft 56 is much smaller than the distance between the conductive portion 552 of the swing link 55 and the hinge shaft 56, as shown in fig. 19, the small swing of the contact portion 551 is amplified into a large swing by the conductive portion 552. The conductive portion 552 contacts the coil of the slide varistor 57, thereby adjusting the variable resistance of the slide varistor 57 into the circuit. The joint connection of the sliding rheostat 57 and the fixed resistor into the circuit for measuring the resistance of the sliding rheostat is prior physical knowledge and is not described in detail herein. The maximum difference of the sliding rheostat resistances obtained through measurement and calculation corresponds to a specific radial run-out value of the bearing outer ring 41 to be detected. According to the resistance change of the slide rheostat, whether the radial runout of the outer ring 41 of the bearing to be detected is within an error allowable range can be known, and further the radial runout detection of the outer ring 41 of the bearing 4 to be detected is realized.

After the detection is finished, the clamping mechanism loosens the bearing 4 to be detected, the support 31 is far away from the material channel 1 under the action of the translation cylinder 32, and the clamping of the bearing to be detected is released. At this time, the friction wheel 81 pushes the bearing 4 to be detected out of the material stopping hole 14 and still contacts with the outer ring of the bearing 4 to be detected, so that the bearing 4 to be detected passes through the material stopping hole 14 under the self weight, then the discharge chute 12 continues to roll forwards, and the next process is carried out.
