Description

Technical Field

[0001] The present application relates to a detection device, and in particular to a bearing ring eddy current detection device. Background Art

[0002] During the production process, cracks may appear on the surface of bearing rings, which may cause the finished products to be unqualified and defined as defective products. Therefore, the finished products need to be tested.

[0003] The usual detection method is magnetic particle testing, which uses magnetic powder as a display medium to observe defects. After the bearing ring is magnetized, the discontinuity caused by the crack causes local distortion of the magnetic lines of force on the surface and near the surface of the bearing ring, generating a leakage magnetic field. The magnetic powder applied to the workpiece surface is adsorbed and forms visible magnetic marks under appropriate lighting, thereby showing the location, size, shape and severity of the discontinuity. Workers can then determine the presence of cracks on the bearing ring. However, this detection method requires manual observation, which affects the inspection efficiency of the product.

[0054] The implementation principle of the eddy current detection device for a bearing ring in the embodiment of the present application is as follows: the bearing ring is placed in the vibration plate 13, the guide rail 512 is used to transport the bearing ring to the conveyor belt 516, the fifth motor 513 drives the driving shaft 514 to rotate, and the driving shaft 514 drives the conveyor belt 516 to transport the bearing ring, and the guide channel 5111 is used to transport the bearing ring to the vicinity of the baffle 521, and the baffle 521 blocks the bearing ring, then the piston rod of the sixth cylinder 526 extends, driving the push plate 529 to slide, so that the bearing ring is located in the notch 5291 of the push plate, then the piston rod of the fifth cylinder 525 contracts, driving the sliding block 524 to slide, and the push plate 529 pushes the bearing ring to the first mounting seat 7, and the piston rod of the first cylinder 2145 drives the first telescopic rod 2 146 rises, the first telescopic rod 2146 drives the first limit block 2173 to rise, and the first limit block 2173 limits the bearing ring. Then the second cylinder 223 drives the first lifting plate 224 to descend, and the first lifting plate 224 drives the first pressure plate 225 to descend, so that the first pressure plate 225 abuts against the bearing ring to limit the bearing ring. Then the second motor 227 drives the first threaded rod 228 to rotate, and the first threaded rod 228 drives the first sliding seat 229 to slide. The first sliding seat 229 drives the first eddy current detection probe 23 to descend, and the first motor 211 drives the first rotating shaft 214 to rotate. The first rotating shaft 214 drives the first mounting seat 7 to rotate, so that the bearing ring rotates, and the first eddy current detection probe 23 detects the upper end surface and the inner wall of the bearing ring.After the inspection is completed, the pushing plate 529 pushes the bearing ring into the slot 421 of the flip shaft 42, and then the sixth motor 41 drives the flip shaft 42 to rotate, so that the flip shaft 42 drives the bearing ring to flip, so that the lower end surface of the bearing ring faces upward, and then the pushing plate 529 is used to push the bearing ring onto the second mounting seat 318, and the third cylinder 3145 drives the second telescopic rod 3146 to rise, and the second telescopic rod 3146 drives the second limit block 3171 to rise and insert into the bearing ring to limit the bearing ring, and then the fourth cylinder 323 drives the second lifting plate 324 to descend, and the second lifting plate 324 drives the second pressure plate 325 to descend, so that the second pressure plate 325 abuts against the bearing ring to limit the bearing ring, and the fourth motor 327 drives the second threaded rod 328 to rotate The second threaded rod 328 drives the second sliding seat 329 to slide, which in turn drives the second eddy current detection probe 33 downward. The third motor 311 drives the second rotating shaft 314 to rotate, which in turn drives the second mounting seat 318 to rotate, thereby rotating the bearing ring. The second eddy current detection probe 33 inspects the lower end surface and outer wall of the bearing ring. After the inspection is completed, the push plate 529 continues to push. If a scratch is detected on the bearing ring, the push plate 529 pushes the bearing ring onto the lifting block 62. The piston rod of the seventh cylinder 61 then drives the lifting block 62 upward. The piston rod of the eighth cylinder 63 retracts, driving the shifting block 64 to push the bearing ring on the lifting block 62 onto the material guide track 65. Finally, the material collection box 66 collects the scratched bearing ring.
