Description

Technical Field

[0001] The invention relates to the technical field of bearing ring detection equipment, and more specifically to a bearing ring full detection equipment adopting magnetic field induction technology. Background Art

[0002] At present, bearing rings (including inner rings and outer rings) are important components of bearings. As supporting parts of rotating shafts, bearings must not only bear large dynamic loads but also play a good transition support role between dynamic and static. Therefore, their quality directly affects the life and performance of mechanical equipment. The most important quality parameters of bearing rings are their processing quality, crack defects, surface hardness, etc. The existing automatic detection equipment for bearing rings generally detects the hardness, external dimensions and surface crack defects of bearing rings. Among them, the detection of bearing ring hardness mainly adopts impact hardness testing machine for testing. The test can only test a few points on the shaft sleeve ring, and often tests the hardness of the outer surface of the shaft sleeve ring, and cannot test the hardness of the internal in and out. For heat-treated shaft sleeve rings, the test data is not comprehensive and accurate enough, and the hardness testing machine is often independent and troublesome to test, and cannot be connected in series with the automated detection line. Therefore, the hardness of the same batch of heat-treated bearing rings is often sampled and cannot be fully inspected;

[0003] At the same time, crack defects on the upper surface of the bearing ring are often detected by industrial cameras. Industrial cameras can detect defects on the outer surface of the bearing ring through video comparison, but cannot detect crack defects inside the bearing ring. Therefore, it is necessary to design an automated detection equipment that can fully inspect the hardness of the bearing ring and can comprehensively detect crack defects on the bearing ring.

[0046] Working principle: The present invention is a bearing ring full inspection device using magnetic field induction technology. The technical points are as follows: one is that a hardness detection component 40 is added to the inspection line, and the other is that a flaw detection component 60 is added;

[0047] The hardness detection component 40 mainly performs magnetic induction on the bearing ring through the excitation coil. The induced electromotive force received by the detection coil is related to the shape and size of the hysteresis loop of the bearing ring. When the low-frequency sinusoidal excitation voltage performs magnetic induction, the induced electromotive force obtained is also a sinusoidal waveform, usually including a fundamental wave. By measuring the fundamental wave component of the induced electromotive force of the detection coil, the measured alloy composition, heat treatment state and other characteristics can be detected; therefore, the metallographic composition of the bearing ring after heat treatment or before heat treatment can be detected, and the hardness of the bearing ring can be obtained through the metallographic composition, and the hardness of the entire bearing ring can be measured;

[0048] During the specific detection, the first lifting cylinder 42 is driven to lift the bearing ring into the nylon seat 44 by the lifting seat 41, and the bearing ring is magnetically induced by the coil in the nylon seat 44; after the detection, the lifting seat 41 is reset, and the lifting structure facilitates the rapid detection of the hardness of each bearing ring;

[0049] The flaw detection assembly 60 includes an external flaw detection mechanism 61, an internal flaw detection mechanism 62, and a flip mechanism 63 disposed between the external flaw detection mechanism 61 and the internal flaw detection mechanism 62. During specific operation;

[0050] The feeding mechanism 30 moves the bearing ring to the positioning turntable 651 of the external flaw detection mechanism 61, and starts the positioning cylinder 681. The positioning cylinder 681 pushes the bearing ring to abut against the rear positioning wheel 672, so that the center of the bearing ring coincides with the center of the positioning turntable 651. Then, the lifting actuator 66 on the external flaw detection mechanism 61 is started. The lifting actuator 66 moves the head of the external cylindrical flaw detection probe 612 to the outer wall of the bearing ring, and moves the head of the first end surface flaw detection probe 613 to the upper side of the upper end surface of the bearing ring; then, the rotating motor 652 is started to rotate the bearing ring, and the first end surface flaw detection probe 613 and the external cylindrical flaw detection probe 612 perform flaw detection on the upper end surface and outer wall of the bearing ring and a part of the ring wall;

[0051] After completing one detection test, the feeding mechanism 30 moves the bearing ring to the lower flip plate 631 and the upper flip plate 635 of the flip mechanism 63, and the clamping cylinder 634 is started to realize the downward movement of the clamping plate 637 to cooperate with the lower flip plate 631 to clamp the bearing ring; then the rotating cylinder 639 rotates the bearing ring to flip 180 degrees, that is, the bearing ring is flipped, and then the clamping cylinder 634 is reset to prepare for the next detection test;

[0052] The feeding mechanism 30 moves the bearing ring in the flipping mechanism 63 to the positioning turntable 651 of the inner flaw detection mechanism 62, and starts the positioning cylinder 681. The positioning cylinder 681 pushes the bearing ring to abut against the rear positioning wheel 672, so that the center of the bearing ring coincides with the center of the positioning turntable 651, and then starts the lifting actuator 66 on the inner flaw detection mechanism 62. The lifting actuator 66 moves the head of the inner circle flaw detection probe 622 into the bearing ring and faces the inner wall of the bearing ring, and moves the head of the second end face flaw detection probe 623 to above the lower end face of the bearing ring (the lower end face of the bearing ring has been moved to the upper side by flipping); then the rotating motor 652 is started to realize the rotation of the bearing ring, and the second end face flaw detection probe 623 and the inner circle flaw detection probe 622 perform flaw detection on the lower end face and outer wall of the bearing ring and a part of the ring wall; thus, a comprehensive flaw detection of the bearing ring is realized.

Any person skilled in the art may modify the embodiments without violating the spirit and scope of the present invention, and therefore, the scope of protection of the present invention shall be as set forth in the claims of the present invention.
