Description

Technical Field

[0001] This utility model relates to the field of flaw detector technology, and in particular to a novel bearing roller flaw detector. Background Technology

[0002] In the precision manufacturing field of modern industry, bearings, as key basic components, are widely used in many industries such as machinery equipment, automobile manufacturing, and aerospace. Their quality and performance directly affect the operational reliability and lifespan of the entire mechanical equipment. As a core component of bearings, bearing rollers require precise detection of their surface and internal defects. The new bearing roller flaw detector focuses on solving the fixing problem in the bearing roller flaw detection process. Through ingenious structural design, it can not only quickly and stably clamp bearing rollers of different sizes to ensure the accuracy of flaw detection, but also adapt to diverse production needs, greatly improving flaw detection efficiency. This provides a solid guarantee for the high-quality development of the bearing manufacturing industry and helps enterprises gain an advantage in the fierce market competition with superior quality.

[0003] Traditional equipment used for flaw detection of bearing rollers has many limitations in terms of the mechanical structure for fixing the rollers. Commonly used equipment often employs a rigid clamp of a single size or a simple three-jaw chuck structure. The clamp is usually customized according to a certain standard size bearing roller. In principle, the roller is fixed by manually tightening the nut or rotating the chuck wrench to make the clamping parts of the clamp tighten inward.

[0004] However, traditional bearing roller flaw detectors struggle to effectively fix bearing rollers of different sizes. On the production lines of large bearing manufacturers, due to the diverse product specifications and varying bearing roller sizes—ranging from tiny rollers in micro-bearings to robust rollers in large industrial bearings—the size range is enormous. Traditional flaw detectors, with their simple fixing structures, cannot quickly and accurately adapt to such size variations. Workers are forced to spend considerable time adjusting fixtures or preparing multiple sets of fixtures, which not only delays production and increases labor costs but also introduces detection errors due to insecure or over-fixed fixing. Therefore, a new type of bearing roller flaw detector is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of bearing roller flaw detector, which aims to improve the problem in the prior art that it is difficult to effectively fix bearing rollers of different sizes, and that a lot of time is required to adjust the fixture or prepare multiple sets of fixtures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel bearing roller flaw detector includes a machine body, a slide table slidably connected to one side of the machine body, a support platform fixedly connected to one side of the slide table, a cylinder fixedly connected to one side of the support platform, a conical column fixedly connected to the output end of the cylinder, a fixing component provided on the other side of the support platform, and an adjustment component provided on one side of the slide table.

[0008] The fixing assembly includes a fixing plate, one side of which is fixedly connected to the other side of the support platform. A sliding groove is formed inside the fixing plate, and a slider is slidably connected inside the sliding groove. The slider contacts the conical column. A locking block is fixedly connected to one side of the slider. A support column is fixedly connected inside the fixing plate. The slider is slidably connected to the outer wall of the support column. A spring is sleeved on the outer wall of the support column, and both ends of the spring are fixedly connected to the slider and the fixing plate, respectively.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a support frame and a fixing block. One side of the support frame is fixedly connected to one side of the slide table, and one end of the fixing block is fixedly connected to one side of the support frame.

[0011] As a further description of the above technical solution:

[0012] A motor is fixedly connected to one side of the support frame, and a crank is fixedly connected to the output end of the motor;

[0013] As a further description of the above technical solution:

[0014] A transmission column is rotatably connected to one side of the crank, and a connecting column is fixedly connected to one end of the transmission column.

[0015] As a further description of the above technical solution:

[0016] A connecting frame is fixedly connected to one end of the connecting column, and a flaw detector is provided on one side of the connecting frame;

[0017] As a further description of the above technical solution:

[0018] A fixed column is fixedly connected to the outer wall of the connecting column, and a rotating ring is rotatably connected to the outer wall of the fixed column;

[0019] As a further description of the above technical solution:

[0020] A connecting rod is fixedly connected to the outer wall of the rotating ring, and a connecting ring is fixedly connected to one side of the connecting rod. The connecting ring is rotatably connected to the outer wall of the fixed block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the conical column is driven by a cylinder to move, which pushes the slider to slide in the groove, so that the locking block opens and supports the roller. At the same time, the slider squeezes the spring, which achieves the effect of quickly and effectively fixing bearing rollers of different sizes. This solves the problem that it is difficult to effectively fix bearing rollers of different sizes, and a lot of time is needed to adjust the fixture or prepare multiple sets of fixtures, thereby improving the applicability of the flaw detector.

[0023] 2. In this utility model, the crank is driven by a motor to rotate, and the transmission is carried by the transmission column and connecting column, so that the connecting ring rotates on the outer wall of the fixed block, causing the flaw detector to swing in all directions. This achieves the effect that the angle of the flaw detector can be adjusted as needed, which solves the problem that the traditional flaw detector has a single flaw detection angle, making it difficult to fully detect roller defects and affecting the accuracy of flaw detection, thereby improving the flexibility of the flaw detector.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3The present invention provides an embodiment of a novel bearing roller flaw detector, comprising a body 1, a slide table 2 slidably connected to one side of the body 1, an electric drive device on the slide table 2, which can be precisely adjusted as needed during operation, a support platform 3 fixedly connected to one side of the slide table 2, a cylinder 4 fixedly connected to one side of the support platform 3, a conical column 5 fixedly connected to the output end of the cylinder 4, the conical column 5 moving forward or backward according to the push of the cylinder 4, thereby driving the slider 8 to slide along the trajectory of the slide groove 7, a fixing component is provided on the other side of the support platform 3, and an adjustment component is provided on one side of the slide table 2;

[0032] The fixing assembly includes a fixing plate 6, which is fixedly connected to the support platform 3 on one side. A groove 7 is provided inside the fixing plate 6, and a slider 8 is slidably connected inside the groove 7. The slider 8 is in contact with the conical column 5, and the outer side of the slider 8 is in contact with the conical column 5. The slider 8 is displaced by the push of the conical column 5. A locking block 9 is fixedly connected to one side of the slider 8. When the cylinder 4 pushes the conical column 5, the locking block 9 will expand outward, thereby firmly clamping the inner wall of the bearing roller. A support column 10 is fixedly connected inside the fixing plate 6, and the slider 8 is slidably connected to the outer wall of the support column 10. A spring 11 is sleeved on the outer wall of the support column 10. The two ends of the spring 11 are fixedly connected to the slider 8 and the fixing plate 6 respectively. After the flaw detection is completed, the spring 11 pushes the slider 8 back to the initial position through the rebound action, thereby automatically releasing the locking block 9, so that the bearing roller can be easily removed.

[0033] Specifically, when using this flaw detector to inspect bearing rollers, the bearing rollers must first be accurately inserted into the outer walls of multiple sliders 8 to ensure their stability. At this time, the output end of the cylinder 4 transmits power through the drive device, driving the conical column 5 to move forward or backward. After being subjected to force, the conical column 5 pushes the sliders 8 on the outer wall to slide smoothly along the slide groove 7. Since the slide groove 7 has a certain guiding effect, the movement path of the slider 8 is restricted and controlled. When the slider 8 begins to slide, it will drive the locking block 9 connected on one side to expand outward. The locking block 9 firmly fixes the inner wall of the bearing roller, ensuring that sufficient clamping force can be provided for different sizes of bearing rollers, preventing the bearing rollers from shifting during the flaw detection process. At the same time, the slider 8 is connected to the spring 11, and the movement of the slider 8 will exert a squeezing effect on the spring 11, causing it to compress. In this way, the spring 11 can store a certain amount of energy by contraction to support subsequent operations. When the inspection of the bearing roller is completed and it needs to be removed, the spring 11 will automatically return to its original state and push the slider 8 back to the initial position by rebound, thereby releasing the bearing roller and making it easy to remove. This ensures that the equipment can adapt to bearing rollers of different sizes and can efficiently fix and disassemble them.

[0034] Reference Figure 2 and Figure 4The adjustment assembly includes a support frame 12 and a fixing block 23. One side of the support frame 12 is fixedly connected to one side of the slide table 2, and one end of the fixing block 23 is fixedly connected to one side of the support frame 12. A motor 13 is fixedly connected to one side of the support frame 12, and a crank 14 is fixedly connected to the output end of the motor 13. The motor 13 serves as a power source, driving the crank 14 to rotate. The rotational motion is transmitted to the connecting column 16 via a transmission column 15. The transmission column 15 is rotatably connected to one side of the crank 14, and the connecting column 16 is fixedly connected to one end of the transmission column 15. A connecting frame 17 is fixedly connected to one end of the column 16. A flaw detector 18 is provided on one side of the connecting frame 17 to make contact with the bearing roller and perform flaw detection. A fixed column 19 is fixedly connected to the outer wall of the connecting column 16. A rotating ring 20 is rotatably connected to the outer wall of the fixed column 19. The rotating ring 20 is connected to the connecting rod 21. This structure enables flexible adjustment of the flaw detector 18. A connecting rod 21 is fixedly connected to the outer wall of the rotating ring 20. A connecting ring 22 is fixedly connected to one side of the connecting rod 21. The connecting ring 22 is rotatably connected to the outer wall of the fixed block 23.

[0035] Specifically, when adjusting the flaw detection angle, the motor 13 first outputs power through the transmission mechanism to drive the crank 14 to rotate. The rotation of the crank 14 causes the transmission column 15 connected on one side to move linearly. The transmission column 15 is connected to the connecting column 16. The movement of the transmission column 15 pushes the connecting column 16 to move linearly or rotationally. The other end of the connecting column 16 is connected to the rotating ring 20 through the fixed column 19. After the fixed column 19 is subjected to force, it drives the rotating ring 20 to move accordingly. The rotating ring 20 is connected to the outer wall of the fixed block 23 through the connecting rod 21, which drives the connecting rod 21 to rotate in different directions. The other end of the connecting rod 21 is connected to the connecting ring 22. The connecting ring 22 rotates smoothly on the outer wall of the fixed block 23, so that the flaw detector 18 can swing accurately at multiple angles, ensuring that the flaw detector 18 can perform comprehensive inspection at different parts and angles inside the bearing rollers.

[0036] Working principle: When using this flaw detector, the bearing rollers are first inserted into the outer wall of multiple sliders 8. Then, the output end of the cylinder 4 drives the conical column 5 to move. The conical column 5, under force, pushes the sliders 8 on the outer wall to slide inside the groove 7. This causes the sliders 8 to push the locking block 9 connected on one side outward, so that the locking block 9 supports and fixes the bearing rollers inside. At the same time, during the movement of the sliders 8, the spring 11 connected on one side is also compressed, causing it to contract. When the bearing rollers are removed, the spring 11 will release the force and rebound, pushing the sliders 8 to reset. This achieves the effect of effectively fixing bearing rollers of different sizes. When performing flaw detection, the flaw detector 18 is first inserted into the bearing rollers. The internal flaw detector is inspected, and then the crank 14 is rotated by the output of the motor 13. The crank 14 drives the transmission column 15 connected to one side to move. The transmission column 15 drives the connecting column 16 at one end to move. The connecting column 16 drives the fixed column 19 connected to the outer wall to move. The fixed column 19 drives the rotating ring 20 connected to the outer wall to move. The rotating ring 20 drives the connecting rod 21 on the outer wall to move. This causes the connecting rod 21 to drive the connecting ring 22 connected to one side to rotate on the outer wall of the fixed block 23. This causes the connecting column 16 to drive the flaw detector 18 on one side to swing in all directions, thereby achieving the effect of adjusting the angle of the flaw detector 18.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
