In practical operation, when a plurality of bearings to be detected fall into the first guide plate 2, the first baffle plate 3 and the second baffle plate 4 prevent the plurality of bearings from falling out of the first guide plate 2, the first guide plate 2 is obliquely arranged, so the plurality of bearings all move downwards, when the first baffle plate moves to the first material blocking mechanism 16, the first motor 162 of the first material blocking mechanism 16 is started, the output shaft of the first motor 162 rotates to drive the rotating shaft to rotate, the rotating shaft rotates to drive the disc 163 to rotate, when the disc 163 rotates, the lug 164 touches the bulge 166 of the limiting rod 165, so that the limiting rod 165 slightly moves upwards, when the limiting rod 165 slightly moves upwards, the front end of the limiting rod 165 leaves the limiting groove 1671 of the first rotating disc 167, so that the limiting rod 165 is not fixed with the first rotating disc 167, the force of the downward movement of one bearing ring drives one blocking rod 169 to rotate, so that the whole second material blocking rod 169 rotates, when the second rotating disc 168 rotates, the rotating shaft and the first rotating disc 167 are driven to rotate respectively, when the bump 164 passes through the protrusion 166, the limiting rod 165 resets, the other limiting groove 1671 of the first rotating disc 167 just rotates to the front end of the limiting rod 165, and finally the front end of the limiting rod 165 continuously falls into the limiting groove 1671, so that the limiting rod 165 and the first rotating disc 167 are continuously fixed, and the material blocking rod 169 continuously blocks the rest bearing rings.

When a bearing continues to move downwards to the limiting block 18 through the first material blocking mechanism 16, the two sharp corners 19 of the limiting block 18 can detect whether the two sides of the outer ring of the bearing finish polishing and chamfering or not, if the bearing is qualified, the bearing continues to move downwards, and finally enters the second guide plate 6 through the limiting block 18, if the bearing does not finish polishing and chamfering or does not meet the qualified requirement, the bearing can be clamped by the two sharp corners 19, and only an operator needs to take out the bearing. When the bearing passing through the limiting block 18 reaches the pressure sensor 28 on the second guide plate 6, the pressure sensor 28 receives pressure and sends a signal to start the first air cylinder 23, the piston rod of the first air cylinder 23 extends to drive the lifting block 24 to move downwards, the lifting block 24 moves downwards to drive the detection head 27 to move downwards and also drive the support block 26 to move downwards, when the support block 26 moves downwards, one end of the connecting rod 251 is driven to move downwards, the other end of the connecting rod 251 moves upwards by taking the support rod 252 as a center, when one end of the connecting rod 251 moves downwards, the stopper 253 is driven to move downwards until the stopper 253 blocks the bearing, the fact that the subsequent bearing can collide with the bearing which is being detected is avoided, therefore, the detected data are inaccurate, and when the other end of the connecting rod 251 moves upwards by taking the support rod 252 as a center, the plurality of springs 254 are also driven to be tensioned.

When the detection head 27 moves downwards and abuts against the outer ring of the bearing, the second motor 311 of the abutting mechanism 31 is started, the output shaft of the second motor 311 rotates forwards to drive the gear 312 to rotate forwards, the gear 312 rotates forwards to drive the rack 313 to move forwards, when the rack 313 moves forwards, the sliding block is driven to slide forwards in the sliding groove, the detection rod 315 is driven to move forwards, when the detection rod 315 reaches the inside of the bearing ring, the second cylinder 314 is started, the piston rod of the second cylinder 314 extends to drive the detection rod 315 to slide downwards in the sliding groove 316 until the detection rod 315 reaches the circular groove in the bearing ring. Then, an operator can observe whether the outer spherical surface of the bearing outer ring and the circular groove in the bearing outer ring are qualified or not through the bearing detector 15, if the bearing is detected to be qualified, the third cylinder 292 of the blocking mechanism 29 is started, the piston rod of the third cylinder 292 extends to drive the blocking block 293 to move forwards until the blocking block 293 blocks the discharge hole 30, and the qualified bearing finally falls into the material collecting box 11 through the inclined guide plate two 6. If it is unqualified to detect out, the piston rod of three 292 of cylinder contracts and drives sprue 293 backward and removes, resets until sprue 293, and unqualified bearing falls into to the flitch 9 through discharge gate 30, and the flitch 9 is fallen out to the unqualified bearing of striker plate 10 avoidance, because the flitch 9 is the slope setting, so finally unqualified bearing passes through inside the flitch 9 falls into the dump bin 12.
