Description
Technical Field
[0001] This invention relates to the technical field of bearing ring eddy current testing machines and systems, and particularly to a bearing ring eddy current testing machine and system. Background Technology
[0002] In the machinery industry, bearings, as crucial components connecting various types of machinery, often exhibit quality defects during assembly. If these defects are not detected in time, they will lead to product non-compliance. Therefore, bearings must undergo rigorous testing before leaving the factory to ensure quality. Traditional bearing inspection methods largely rely on manual inspection, but this approach suffers from high costs and low efficiency. With technological advancements, bearing inspection is gradually transforming towards non-contact, digital, and online inspection methods. By combining advanced computer vision and automated inspection technologies, machine vision is increasingly achieving deep integration with industrial systems.
[0003] Currently, one of the most commonly used bearing inspection techniques is eddy current testing. Eddy current flaw detectors can quickly inspect the inner wall of bearing races, obtaining relatively accurate test data. However, eddy current testing technology also has certain limitations. For example, when dust, oil, or other impurities accumulate on the inner wall of the bearing races, these contaminants can interfere with the signal from the eddy current flaw detector, leading to inaccurate test results and affecting the final judgment. Furthermore, during long-term digital inspections, other steps prior to eddy current testing may also affect the inner wall of the bearing races, thus impacting the accuracy of the eddy current test. Summary of the Invention
[0004] The main objective of this invention is to provide a bearing ring eddy current testing machine and system, which aims to ensure that the inner wall of the bearing ring remains clean and improve the testing accuracy of the eddy current testing module.
[0005] To achieve the above objectives, the present invention provides a bearing ring eddy current testing machine, comprising: The frame is equipped with a testing platform that supports other components, and a conveyor is fixedly connected to the testing platform. The feeding module uses a vibratory feeder to sequentially feed the processed bearing rings onto the conveyor table and move them stably. The inner gauge inspection module, in conjunction with the pusher module, sequentially inspects the inner diameter of the bearing rings; An eddy current testing module, in conjunction with a feeding module, performs eddy current testing on the inner wall of the bearing ring that has passed the internal gauge test. The eddy current testing module includes an eddy current flaw detector. A brushing module is installed between the inner gauge detection module and the eddy current detection module. It is used to clean the inner wall of the bearing ring after it passes through the inner gauge detection module, thereby improving the accuracy of the eddy current detection. The main control module is located on the outside of the frame and is used to facilitate the user to summarize the detection information of the bearing rings inside the frame and to facilitate the user to collect the collected data.
[0006] In one possible implementation, the scrubbing module includes: A brushing seat is fixedly connected to a conveyor table. A first cylinder is fixedly connected to the brushing seat, and a first positioning plate is slidably connected to the brushing seat. The telescopic shaft of the first cylinder is fixedly connected to the first positioning plate. A washing disc is rotatably connected to the lower side of a first positioning plate. A first motor is fixedly connected to the upper side of the first positioning plate. The drive shaft of the first motor is fixedly connected to the washing disc. Several soft brush heads are connected to the washing disc. A dust collection module is installed between the detection platform and the conveyor table, and is used to work with a soft brush head to absorb dirt from the inner wall of the bearing ring.
[0007] In one possible implementation, the scrubbing disc has several grooves, and each of the soft brush heads abuts against the inner wall of the groove.
[0008] In one possible implementation, the vacuuming module includes: A positioning disk, which is detachably and fixedly connected to the detection platform; A vacuum cleaner cylinder, which slides and abuts against a positioning plate, and has several air outlet slots at its upper end; The first positioning post has its upper end tightly abutting against the inner wall of the dust collection cylinder, and its lower end is fixedly connected to the detection platform. A lifting seat is fixedly connected to the detection platform. A second cylinder is fixedly connected to the lifting seat, and a lifting block is fixedly connected to the telescopic shaft of the second cylinder. A lifting plate is fixedly connected to the outer wall of the vacuum cleaner, and the end of the lifting plate away from the vacuum cleaner abuts against the side of the lifting block.
[0009] In one possible implementation, a positioning sleeve is fixedly connected to the outer ring of the vacuum tube, and a plurality of limiting seats are fixedly connected to the lower side of the positioning plate. A second locking plate is hinged to each of the limiting seats, and the positioning sleeve abuts against the side of each of the second locking plates away from the adjacent limiting seat.
[0010] In one possible implementation, the positioning disk has a plurality of gap grooves, and each of the second positioning plates abuts against each gap groove.
[0011] In one possible implementation, the second locking plate is hinged to the limiting seat on the side of the second locking plate facing the limiting seat, and a gravity groove is provided on the second locking plate.
[0012] In one possible implementation, a second positioning post is fixedly connected to the second positioning plate.
[0013] In this invention, the user controls and monitors each workstation within the frame via a main control module connected to an electronic control screen. This technique is common in the industry and will not be described in detail here. After the finished bearing rings are continuously fed into the frame via a vibratory feeder, they move to the conveyor table and are stably advanced by the pushing module to the inner gauge inspection module, the brushing module, and the eddy current inspection module. First, the inner gauge inspection module checks the basic dimensions of the bearing rings. Qualified bearing rings are then pushed to the brushing module. In the brushing module, a first cylinder drives the soft brush head downwards. The system moves, and several soft brush heads enter the center of the bearing race and begin to rotate slowly. Driven by the first motor, they mechanically scrub the inner wall of the bearing race to remove dirt. Then, a dust collection module works in conjunction to absorb the dust and dirt generated during the scrubbing process, preventing these substances from causing secondary pollution to the workshop equipment. This ensures that the inner wall of the bearing race remains clean, improving the detection accuracy of the eddy current detection module. Because the bearing race remains clean, after scrubbing, the bearing race continues to move to the eddy current detection module, which automatically records the detection data into the main control module for easy observation and adjustment by the user.
[0014] Another objective of this invention is to provide a bearing ring eddy current testing system, which aims to effectively reduce the impact of flying dirt and dust on the workshop environment and avoid secondary contamination of the tested bearing rings by this dirt.
[0015] To achieve the above objectives, the present invention proposes a bearing ring eddy current testing system, comprising: S100: Feeding: Through the feeding module, several finished bearing rings are sequentially fed onto the conveyor table via a vibratory feeder, and then the feeding module moves the bearing rings on the conveyor table synchronously. S200: Inner gauge inspection: The pusher module moves the bearing ring to the lower side of the inner gauge inspection module. The inner and outer diameters of the bearing ring are inspected by the gauge in the inner gauge inspection module. The qualified bearing ring continues to move with the pusher module. S300: Brushing: The bearing rings detected by the inner gauge module are moved to the underside of the brushing module by the pushing module. The brushing module mechanically brushes the inner wall of the bearing rings to improve the cleanliness of the inner wall of the bearing rings. S400: Eddy Current Testing: After the bearing rings have been cleaned, they move to the underside of the eddy current testing module along with the pusher module. Eddy current testing is then performed on the inner wall of the bearing rings using the eddy current flaw detector in the eddy current testing module. S500 discharge: After passing the eddy current test, the bearing rings are moved to the subsequent testing area by the pusher module for testing their specific three-dimensional dimensions.
[0016] This invention's technical solution employs a brushing process to further clean the inner walls of bearing rings that have already passed through the internal gauge inspection module. Since bearing rings fed in by the vibratory feeder may contain dirt, this dirt can spread during the internal gauge inspection process, affecting the cleanliness of the inner walls of other bearing rings. Brushing effectively maintains the cleanliness of the bearing ring inner walls, thereby improving the detection accuracy of the eddy current inspection module. Furthermore, the dust and dirt generated during brushing are promptly removed, ensuring that each sequentially fed bearing ring remains clean, facilitating subsequent photographic inspection. Simultaneously, the brushing system effectively reduces the impact of airborne dirt and dust on the workshop environment, preventing secondary contamination of the inspected bearing rings.

[0020] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Example 1
[0022] This invention proposes a bearing ring eddy current testing machine; Reference Figures 1 to 6 In this embodiment of the invention, a bearing ring eddy current testing machine includes a frame 11, a pushing module, an inner gauge testing module, an eddy current testing module, a brushing module, and a main control module. A testing platform 12, which supports other components, is fixedly mounted on the frame 11. A conveyor table 13 is fixedly mounted on the testing platform 12. The pushing module uses a vibrating plate 15 to sequentially feed the processed bearing rings onto the conveyor table 13 and move them stably. The inner gauge testing module, in conjunction with the pushing module, sequentially tests the inner diameter of the bearing rings. The eddy current testing module, in conjunction with the pushing module, performs eddy current testing on the inner wall of the bearing rings that have passed the inner gauge testing. The eddy current testing module includes an eddy current flaw detector 14. The brushing module is located between the inner gauge testing module and the eddy current testing module to clean the inner wall of the bearing rings after they have passed through the inner gauge testing module, improving the accuracy of the eddy current testing. The main control module is located outside the frame 11 to facilitate the user's summarization of the testing information of the bearing rings within the frame 11 and to facilitate the collection of data.
[0023] Users control and monitor each workstation within the frame 11 via the main control module, which is connected to the electronic control screen. This technology is common in the industry and will not be described in detail here. After the finished bearing rings are continuously fed into the frame 11 via the vibratory feeder 15, they move to the conveyor table 13 and are stably advanced to the inner gauge inspection module, the brushing module, and the eddy current inspection module via the pushing module. First, the inner gauge inspection module inspects the basic dimensions of the bearing rings. Bearing rings that pass the inspection are then pushed to the brushing module. In the brushing module, the first cylinder 22 drives the soft brush head 26 to move downwards. After several soft brush heads 26 enter the center of the bearing ring, they begin to rotate slowly. Driven by the first motor 25, they mechanically brush the inner wall of the bearing ring to remove dirt. Then, the dust collection module works in conjunction to absorb the dust and dirt generated during the brushing process, preventing these substances from causing secondary pollution to the workshop equipment and ensuring that the inner wall of the bearing ring remains clean. This improves the detection accuracy of the eddy current detection module. Because the bearing ring remains clean, after brushing, the bearing ring will continue to move to the eddy current detection module. The eddy current detection module will automatically record the detection data into the main control module for easy observation and adjustment by the user.
[0024] refer to Figures 1 to 6 The brushing module includes a brushing base 21, a brushing disc 24, and a dust collection module. The brushing base 21 is fixedly connected to the conveyor table 13. The first cylinder 22 is fixedly connected to the brushing base 21. The first locking plate 23 is slidably connected to the brushing base 21. The telescopic shaft of the first cylinder 22 is fixedly connected to the first locking plate 23. The brushing disc 24 is rotatably connected to the lower side of the first locking plate 23. The upper side of the first locking plate 23 is fixedly connected to the first motor 25. The drive shaft of the first motor 25 is fixedly connected to the brushing disc 24. Several soft brush heads 26 are all arranged on the brushing disc 24.
[0025] The first cylinder 22 in the brushing module drives the soft brush head 26 to move downwards towards the bearing ring. After several soft brush heads 26 have fallen into the center of the bearing ring, the system is slowly started, so that the first motor 25 drives the soft brush head 26 to mechanically brush the inner wall of the bearing ring, so that the dirt on the inner wall of the bearing ring is brushed off.
[0026] In addition, a dust collection module for adsorbing dirt from the inner wall of the bearing ring, which works in conjunction with the soft brush head 26, is installed between the detection platform 12 and the conveyor table 13.
[0027] Based on the above, in conjunction with the dust extraction module, the dust and dirt washed off by the heat sink are absorbed, preventing secondary contamination of the components in the workshop by the dust and dirt washed off, improving the cleanliness of the inner wall of the bearing ring, so that the bearing ring can remain clean even after the inner gauge inspection module, thereby improving the detection accuracy of the eddy current detection module.
[0028] refer to Figures 5 to 6 Several grooves 241 are formed on the washing plate 24, and each soft brush head 26 abuts against the inner wall of the groove 241. When the scrubbing disc 24 rotates, under the action of centrifugal force, each soft brush head 26 can slide along the slide groove 241, allowing each soft brush head 26 to cover a larger area. The user can adjust the scrubbing force of each soft brush head 26 on the inner wall of the bearing ring by adjusting the speed of the scrubbing disc 24, thereby scrubbing the inner wall of the bearing ring more efficiently, ensuring that the inner wall of the bearing ring is not scratched, improving the scrubbing effect on the inner wall of the bearing ring, and improving practicality.
[0029] refer to Figures 1 to 6 The vacuuming module includes a positioning plate 31, a vacuuming cylinder 32, a first positioning post 33, a lifting seat 34, and a lifting plate 37. The positioning plate 31 is detachably and fixedly connected to the detection platform 12. The vacuuming cylinder 32 slides against the positioning plate 31. Several air outlet slots 321 are formed on the upper end of the vacuuming cylinder 32. The upper end of the first positioning post 33 is tightly against the inner wall of the vacuuming cylinder 32. The lower end of the first positioning post 33 is fixedly connected to the detection platform 12. The lifting seat 34 is fixedly connected to the detection platform 12. The lifting seat 34 is fixedly connected to the second cylinder 35. The telescopic shaft of the second cylinder 35 is fixedly connected to the lifting block 36. The lifting plate 37 is fixedly connected to the outer wall of the vacuuming cylinder 32. The end of the lifting plate 37 away from the vacuuming cylinder 32 abuts against the side of the lifting block 36. The second cylinder 35 drives the lifting block 36 to move towards the lifting plate 37, which in turn moves the lifting plate 37 upward along the inclined side of the lifting block 36. This, in turn, moves the dust collection cylinder 32 upward along the first positioning post 33. Then, the part of the inner wall of the dust collection cylinder 32 that was in close contact with the first positioning post 33 will separate, allowing the air chamber inside the dust collection cylinder 32 to circulate. At this time, the air in the dust collection cylinder 32 can be extracted through the pneumatic connector, which can absorb the dust and dirt brushed off the inner wall of the bearing ring by the brushing module. This allows the dirt to be quickly transferred, enabling the brushing module to achieve a good cleaning effect on the bearing ring. At the same time, it ensures the cleanliness of the workshop work area, that is, to ensure the cleanliness of several bearing rings on the entire production line, and improves the detection accuracy of the eddy current detection module for the bearing ring.
[0030] refer to Figures 3 to 6 The positioning sleeve 38 is fixedly connected to the outer ring of the vacuum cleaner 32. The lower side of the positioning plate 31 is fixedly connected to several limiting seats 39. Each limiting seat 39 is hinged to each second locking plate 310. The positioning sleeve 38 abuts against the side of each second locking plate 310 away from the adjacent limiting seat 39. By setting the positioning sleeve 38, the vacuum cleaner 32 moves upward and simultaneously drives the positioning sleeve 38 to move upward. Then, with the abutment between the positioning sleeve 38 and the side of the second locking plate 310, several second locking plates 310 are flipped upward in the direction of the axis of the positioning sleeve 38. This allows the outer wall of the bearing ring to be limited when the bearing outer ring is cleaned with the brushing module, so that the bearing ring can be cleaned more stably, improving the stability and brushing effect of the brushing module.
[0031] refer to Figures 3 to 6 Several gap grooves 311 are provided on the positioning plate 31, and each second locking plate 310 abuts against each gap groove 311. The opening of each gap groove 311 serves to limit the flipping of each second positioning plate 310 and leaves space for the flipping of the second positioning plate 310.
[0032] refer to Figures 3 to 6 The hinge position of the second positioning plate 310 and the limiting seat 39 is biased towards the side of the second positioning plate 310 facing the limiting seat 39, and the gravity groove 312 is formed on the second positioning plate 310. When the second positioning plate 310 is not subjected to external force, its hinge position with the limiting seat 39 is biased towards the side of the second positioning plate 310 facing the limiting seat 39. Therefore, the center of gravity of the second positioning plate 310 itself is oriented to the other side. When the second positioning plate 310 is not subjected to the upward force of the positioning sleeve 38, it will reset under the action of gravity. This makes the upper end of the second positioning plate 310 lower than the upper side of the positioning disk 31, so that the positioning function of the second positioning plate 310 on the bearing ring will not interfere with the pushing module, thus ensuring the stability of the operation of each component.
[0033] refer to Figures 3 to 6 The second card plate 310 is fixedly connected to the second positioning post 313; When the second positioning plate 310 flips upward, the second positioning posts 313 abut against the outer wall of the central bearing ring, improving the positioning effect. At the same time, compared with the abutment and limiting effect of the side of the second positioning plate 310 against the outer wall of the bearing ring, the contact area with the outer wall of the bearing ring is reduced, thus having a higher pressure effect under the same force, making the bearing ring more stable during cleaning. In addition, it also reduces the contact wear between the two, thereby ensuring that the outer wall of the bearing ring remains smooth and clean. Example 2
[0034] This invention also proposes a bearing ring eddy current testing system, referring to... Figures 1 to 6 include: S100: Feeding: Through the feeding module, several finished bearing rings are fed into the conveyor table 13 in sequence via the vibratory feeder 15, and then the bearing rings on the conveyor table 13 are moved synchronously by the feeding module. The feeding module can sequentially feed each bearing ring to the eddy current detection module, so that the bearing rings can be fed, inspected by the inner gauge module, washed by the brushing module, inspected by the eddy current detection module and discharged at the same time, which improves the stability and synchronization of the bearing ring inspection, and thus enables the bearing rings to be discharged stably. S200: Inner gauge inspection: The pusher module moves the bearing ring to the lower side of the inner gauge inspection module. The inner and outer diameters of the bearing ring are inspected by the gauge in the inner gauge inspection module. The qualified bearing ring continues to move with the pusher module. Before performing eddy current testing on the inner wall of the bearing rings, the inner gauge dimensions of the bearing rings are tested first to screen out the unqualified ones. This reduces the pressure of eddy current testing and allows for stable production of bearing rings.
[0035] S300: Brushing: The bearing rings detected by the inner gauge module are moved to the underside of the brushing module by the pushing module. The brushing module mechanically brushes the inner wall of the bearing rings to improve the cleanliness of the inner wall of the bearing rings. The brushing process further cleans the inner walls of the bearing rings that have already passed through the internal gauge inspection module. Since the bearing rings fed in by the vibratory feeder 15 may contain dirt, this dirt could spread during the internal gauge inspection, affecting the cleanliness of the inner walls of other bearing rings. Brushing effectively keeps the inner walls of the bearing rings clean, thereby improving the inspection accuracy of the eddy current inspection module. Furthermore, the dust and dirt generated during brushing are promptly removed, ensuring that each bearing ring fed out sequentially remains clean, facilitating subsequent photographic inspection. Simultaneously, the brushing system effectively reduces the impact of airborne dirt and dust on the workshop environment, preventing secondary contamination of the inspected bearing rings.
[0036] S400: Eddy current testing: The bearing rings that have been cleaned are moved to the underside of the eddy current testing module along with the pusher module. Eddy current testing is performed on the inner wall of the bearing rings by the eddy current flaw detector 14 in the eddy current testing module. S500 discharge: After passing the eddy current test, the bearing rings are moved to the subsequent testing area by the pusher module for testing their specific three-dimensional dimensions.
