[0002] A bearing is a mechanical element that limits relative motion to the required range of motion and reduces friction between moving parts. It is mainly used to support mechanical rotating bodies, and tapered bearings are a type of bearing.

[0003] Generally, tapered bearings are composed of rings, rolling elements and cages, and the rings usually include an inner ring and an outer ring. The inner ring and the outer ring are designed to match each other. For example, a conical contact surface is designed to allow the inner ring and the outer ring to provide a reasonable load distribution when rotating. This design enables the tapered bearing to comprehensively withstand radial and axial loads.

[0004] At present, it is generally necessary to conduct comprehensive hardness and crack tests on the rings before they can be released from the factory. In order to facilitate the inspection of such rings with conical surfaces, eddy current testing machines capable of eddy current testing are usually used.

[0005] The existing eddy current testing machines for tapered bearing rings usually include a set of eddy current testing devices for detecting hardness and a set of eddy current testing devices for detecting cracks, which are independently set. During the inspection, workers are required to assist in the loading and unloading of materials to cooperate with the two sets of eddy current testing devices to complete the hardness and crack inspections. After the inspection, the qualified products and the unqualified products are manually collected separately.

[0006] Although it is more flexible to load and unload materials with the assistance of workers, production is time-consuming and labor-intensive, and more manual participation leads to lower production efficiency. Summary of the invention

Usually, the distance between the two limit plates 263 is slightly larger than the outer circumferential diameter of the ring.

[0038] Reference Figure 4 The first unloading device 4 includes a frame 41 disposed on the workbench 1, and the frame 41 is provided with a unloading member 42, a discharge member 43 and a collecting pipe 44. The frame 41 is formed with a unloading position 411 and a discharge position 412. The unloading position 411 is located above the discharge position 412.

[0040] Reference Figure 4The collecting pipe 44 includes a pipe body 441 connected to the workbench 1, one pipe mouth of the pipe body 441 is located on the side of the unloading position 412, and the other pipe mouth of the pipe body 441 is provided with a closing plate 442; a notch 4411 is opened on the side wall of the pipe body 441, and a baffle 443 is hinged on the pipe body 441 to close the notch 4411, and the baffle 443 can be rotated to take out the ring.

[0041] Reference Figure 5 The structural difference between the second material discharging device 6 and the first material discharging device 4 is that the shape of the collecting pipe 44 is different; the structures of other parts are the same, so the specific structure of the second material discharging device 6 is not repeated here.

[0042] Reference Figure 5 and Figure 6 The first unloading device 4 is provided with a first calibration mechanism 45, and the second unloading device 6 is provided with a second calibration mechanism 61. The first calibration mechanism 45 is configured to enable the ring to be located at the unloading position 411. The second unloading device 6 is formed with a feeding position 62, and the second calibration mechanism 61 is configured to enable the ring to be located at the feeding position 62.

[0043] Reference Figure 5 and Figure 6 The first calibration mechanism 45 and the second calibration mechanism 61 have the same structure. Take the structure of the first calibration mechanism 45 as an example: the first calibration mechanism 45 includes a frame body 451 arranged on the first unloading device 4, and a reciprocating driving member 452 is provided on the frame body 451. The reciprocating driving member 452 is a cylinder, and the reciprocating driving member 452 is connected to a frame body 453. The frame body 453 is connected to a clamping calibration component 454 for adjusting the position of the ring, and the reciprocating driving member 452 can drive the frame body 453 and the clamping calibration component 454 to move up and down.

[0044] Reference Figure 5 and Figure 6 The clamping calibration component 454 includes a clamping calibration part 4541 connected to the frame body 453, the clamping calibration part 4541 is a clamping cylinder, and two calibration claws 4542 are connected to the clamping calibration part 4541, and the clamping calibration part 4541 can drive the two calibration claws 4542 to move closer to or away from each other; a clamping area 4543 is formed between the two calibration claws 4542, and the end surface of each calibration claw 4542 close to the clamping area 4543 is a calibration surface 45421, and the calibration surface 45421 is a concave arc surface, which is matched with the outer circumferential surface of the ring, and the two calibration surfaces 45421 are configured to be able to approach the position of the calibration ring to each other.

[0045] Usually, there are many structures connected by screws in the assembly line. For the present application, after the present application has been running for a long time, the screws on the first eddy current detection device 3 and the second eddy current detection device 5 may become loose or even fall off, which will make the data inaccurate when performing hardness or crack detection. Therefore, in order to prevent this situation from happening, before starting batch ring detection, it is necessary to select standard samples for loading and testing comparison, wherein the standard sample refers to the ring that has obtained accurate test results; The detection and comparison actions in the present application are: first place the standard sample directly at the unloading position 411, and then drive the reciprocating drive member 452 to drive the two calibration claws 4542 to move down to clamp the ring. The process of the ring being clamped is also the process of the ring being adjusted. Then the material moving device 7 moves the ring to the first eddy current detection device 3 for detection, and compares the detection results with the detection results obtained before the standard sample. If the results are different, it means that there is a problem with the screw tightening and maintenance is required.

[0046] The calibration action of the second calibration mechanism 61 differs from that of the first calibration mechanism 45 in that after placing the standard sample at the feeding position 62, the second calibration mechanism 61 calibrates the standard sample at the feeding position 62, and then the material moving device 7 moves the standard sample to the second eddy current detection device 5 for detection and obtains the results for comparison.

[0047] Reference Figure 7 The material moving device 7 includes a driving assembly 71 disposed on the workbench 1, a frame 5 72 is connected to the driving assembly 71, a plurality of material moving parts 73 are connected to the frame 5 72, and the plurality of material moving parts 73 are distributed at intervals. Specifically, the driving assembly 71 includes a fixed frame 1 711 disposed on the workbench 1, a front and rear reciprocating cylinder 712 is disposed on the fixed frame 1 711, a fixed frame 2 713 is disposed on the front and rear reciprocating cylinder 712, a left and right rough adjustment reciprocating cylinder 714 is disposed on the fixed frame 2 713, a fixed frame 3 715 is disposed on the left and right rough adjustment reciprocating cylinder 714, a fixed frame 3 715 is disposed on the left and right fine adjustment reciprocating cylinder 716, and the frame 5 72 is connected to the left and right fine adjustment reciprocating cylinder 716.

[0048] Reference Figure 6 and Figure 7 The material moving member 73 includes a mounting plate 731 detachably connected to the frame body 5 72, and the mounting plate 731 includes a material moving surface 7311 at the end, and an inner concave surface 7312 is formed on the material moving surface 7311. The inner concave surface 7312 is used to make it difficult for the ferrule to be misplaced when the material moving member 73 moves the ferrule.

[0049] The implementation principle of the fully automatic tapered bearing ring eddy current testing machine in the embodiment of the present application is: The rings from the previous process flow to the feeding position 241, and the driving member 25 drives the conveyor belt 24 to work and transport the rings from the feeding position 241 to the waiting position 242; The material moving device 7 moves the ferrule to the first eddy current detection device 3, and the first eddy current detection device 3 performs hardness detection on the ferrule; The material moving device 7 moves the ferrule to the supporting circular plate 422, i.e., the unloading position 411. If the hardness test of the ferrule fails, the unloading cylinder 421 drives the supporting circular plate 422 to move down to the unloading position 412, and the unloading cylinder 431 drives the unloading plate 432 to move and push the ferrule at the unloading position 412 into the collecting pipe 44. If the hardness test of the ferrule passes, the supporting circular plate 422 does not move, and the material moving device 7 moves the ferrule to the second eddy current detection device 5. The second eddy current detection device 5 performs crack detection on the ferrule; The material moving device 7 moves the ring to the second unloading device 6. If the ring fails the crack detection, the second unloading device 6 unloads the ring. If the ring passes the crack detection, the material moving device 7 moves the ring and subsequently transfers it to the next process.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
