The working principle of the invention is described below: the bearing mode to be detected is arranged in the discharge groove 12, the bearing 4 to be detected rolls from high to low in the discharge groove 12 under the action of dead weight, the bearings to be detected in the discharge groove 12 are arranged back and forth to form a bearing row, as shown in fig. 3, the bearing 4 to be detected positioned at the forefront side of the bearing row is contacted with the blocking release piece 2, and the bearing row is blocked. The driving gear 23 is driven to rotate, the driven gear 22 is driven to rotate, and then the driving gear 21 is driven to rotate, at the moment, the driving gear 21 drives the blocking release piece 2 to rotate, as shown in fig. 4 and 5, along with the rotation of the blocking release piece 2, the blocking release piece 2 gradually rotates until the opening of the blocking release piece 2 faces the bearing row, as shown in fig. 6, at the moment, the bearing 4 to be detected at the forefront side of the bearing row is released to roll to the inner side of the blocking release piece 2; as shown in fig. 7, as the blocking release member 2 continues to rotate, the blocking release member 2 again achieves blocking of the bearing row, and the released bearing 4 to be detected rolls out of the blocking release member 2 through the opening of the blocking release member 2. When the bearing 4 to be detected rolls to the notch 13, the released bearing 4 to be detected in each discharge groove 12 is clamped in the stopping hole 14. Subsequently, the clamping unit is operated, and the brackets 31 positioned at the front side and the rear side of the material channel 1 are moved to the side close to the material channel 1; in this process, the clamping mechanism on the front side bracket 31 extends into the inner rings of the plurality of bearings 4 to be detected in the front end discharge groove 12, and the clamping mechanism on the rear side bracket 31 extends into the inner rings of the plurality of bearings 4 to be detected in the rear end discharge groove 12. Then the clamping driving mechanism acts to expand the clamping rod 36 outwards, and further supports the inner ring of the bearing 4 to be detected in a three-point contact mode. After the clamping mechanism stretches into the inner ring of the bearing 4 to be detected, the clamping mechanism is biased to the middle upper part of the inner ring of the bearing 4 to be detected, and at the moment, after the clamping rods 36 are outwards expanded, 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 leaves the 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 the detection wheel 52 of the detection unit; at this time, the lifting cylinder 8 is driven to act, so that the friction wheel 82 rises 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 rotation of the friction wheel 82 drives 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 runout occurs, the detection wheel 52 moves up and down while rotating. In the process of moving up and down the detection wheel 52, the driving end 512 of the detection rod 51 is always in contact with the contact portion 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 through 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 to a large swing by the conductive portion 552. The conductive portion 552 is in contact with the coil of the slide rheostat 57, thereby realizing adjustment of the variable resistance of the slide rheostat 57 connected to the circuit. The resistor 57 and the fixed resistor are commonly connected to a circuit for measuring the resistance of the resistor, which is known in the art, and will not be described herein. The maximum difference value of the resistance of the sliding rheostat obtained through measurement and calculation corresponds to a specific radial runout value of the bearing outer ring 41 to be detected. According to the resistance change of the sliding rheostat, whether the radial runout of the outer ring 41 of the bearing to be detected is within the 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 completed, the clamping mechanism loosens the bearing 4 to be detected, and the bracket 31 is far away from the material channel 1 under the action of the translation cylinder 32, so that the clamping of the bearing to be detected is released. At this time, the friction wheel 81 ejects 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 over the material stopping hole 14 under the self weight and then the material discharging groove 12 continues to roll forwards to enter the next process.
