Abstract
Description
Technical Field
[0001] This invention belongs to the field of bearing flaw detection technology, and in particular relates to a bearing ring flaw detection device and its probe mounting bracket. Background Technology
[0002] Bearings are core components of mechanical systems, and their quality directly affects the stable operation of the entire system. Therefore, defect detection of bearing rings is crucial for accurately controlling the quality of produced bearings.
[0003] Non-destructive testing methods such as ultrasonic testing and eddy current testing have been widely used in the field of bearing testing, and can accurately detect defects on the surface or inside of bearing races. Patent CN216816553U (publication date: June 24, 2022) discloses an ultrasonic testing device for bearing races. This device includes a base, a rotating support, and a mounting arm with a testing probe. The mounting arm includes a longitudinal arm and a transverse arm. The longitudinal arm is fixed to the base, and the transverse arm is connected to the longitudinal arm. The probe is mounted on the transverse arm, and the position of the transverse arm relative to the longitudinal arm and the mounting position of the probe relative to the transverse arm are both adjustable. During testing, the bearing race to be tested can be placed on the rotating support, and the position of the probe can be adjusted to fit snugly against the bearing race. Combined with the rotation of the rotating support, omnidirectional testing is completed.
[0004] For large bearings, such as those used in large construction machinery and wind power, the diameter of their bearing rings typically ranges from one meter to several meters. However, the mounting boom of the aforementioned testing device is fixed to the base. To perform flaw detection on bearing rings of different diameters, the horizontal arm of the mounting boom must be long enough to ensure the probe can move laterally. To ensure accurate test results, the horizontal arm also needs to have good stability during the testing process, resulting in high costs. Furthermore, due to the presence of raceways, the probe does not always contact the inner wall of the bearing ring during actual testing. This necessitates a degree of freedom for probe rotation adjustment, further increasing costs.
[0005] Analysis shows that the aforementioned testing devices are not flexibly applicable to large bearings. In actual production, flaw detection still relies on workers holding hand probes, resulting in unreliable test results. Summary of the Invention
[0006] The purpose of this invention is to provide a probe mounting bracket for a bearing ring flaw detection device, thereby solving the technical problem that existing bearing flaw detection devices are difficult to apply to the flaw detection of large bearing rings. Another purpose of this invention is to provide a bearing ring flaw detection device to solve the same technical problem described above.
[0007] To achieve the above objectives, the technical solution for the probe mounting bracket of the bearing ring flaw detection device provided by this invention is as follows:
[0008] A probe mounting bracket for a bearing ring flaw detection device includes a horizontal arm and a probe mounting arm connected to the horizontal arm. The probe mounting arm is provided with a probe mounting seat for mounting a detection probe. The horizontal arm is provided with a clamping structure, which includes an inner clamping body for positioning and fitting against the inner wall surface of the bearing ring and an outer clamping body for positioning and fitting against the outer wall surface of the bearing ring. The horizontal arm or the clamping structure is provided with a support structure for placing on the end face of the bearing ring to support the probe mounting bracket. In use, the horizontal arm can remain stationary relative to the rotation of the bearing ring.
[0009] The beneficial effects are as follows: This invention innovatively proposes a probe mounting bracket that can be hung on bearing races. During inspection, the probe can be installed on the probe mounting base, and then the position of the cross arm is determined by the clamping structure. The cross arm is placed at the end of the bearing race, and with the combined action of the support structure and the clamping structure, the probe mounting bracket is stably hung on the bearing race. At this time, the rotating platform for placing the bearing race can be activated, causing the bearing race and the probe mounting bracket to rotate relative to each other, achieving circumferential flaw detection. Moreover, this invention can be flexibly hung inside or outside the bearing race, thereby achieving flaw detection from both the inner and outer walls of the bearing. The probe mounting bracket in this invention is flexible in use. Compared with manually holding a probe, the position of the probe mounting bracket is relatively fixed, resulting in higher detection accuracy; at the same time, it is not limited by space and can be placed at any position on the bearing race, making it suitable for flaw detection of large bearing races.
[0010] As a further improvement, the position of at least one of the inner clamping body and the outer clamping body can be adjusted laterally relative to the cross arm to change the clamping distance between the inner clamping body and the outer clamping body.
[0011] The beneficial effect is that the clamping body has better versatility and is suitable for bearing rings with different inner and outer diameters (wall thicknesses).
[0012] As a further improvement, the positions of both the inner and outer clamping bodies can be adjusted laterally relative to the cross arm.
[0013] The advantages are: the adjustment is more flexible, allowing for more freedom in setting the probe mounting base. Furthermore, the inner and outer clamps can shift the center of gravity of the cross arm during adjustment, which helps maintain the cross arm's balance.
[0014] As a further improvement, at least one of the inner clamping body and the outer clamping body is formed by a rolling element mounted on the cross arm.
[0015] The beneficial effect is that at least one side of the contact with the collar is a rolling friction fit, which reduces friction and also avoids wear on the collar on that side caused by the clamping body.
[0016] As a further improvement, both the inner and outer clamping bodies are formed from rolling elements mounted on the cross arm.
[0017] The beneficial effect is that it ensures that neither the inner nor outer wall surfaces of the ring will be worn.
[0018] As a further improvement, the number of inner clamps is greater than the number of outer clamps.
[0019] The beneficial effect is that the inner clamp can form a more stable contact with the collar, thereby overcoming the centrifugal force of the collar when it rotates, making the probe mounting bracket more stable.
[0020] As a further improvement, the support structure is formed by rolling elements mounted on the cross arm or clamping structure.
[0021] The beneficial effect is that the friction between the cross arm or clamping structure and the end face of the collar is rolling friction, which can effectively ensure the stability of the probe mounting bracket and avoid wear on the end face of the collar.
[0022] As a further improvement, the position of the probe mounting arm can be adjusted laterally relative to the cross arm.
[0023] The beneficial effect is that it provides another way to adjust the distance between the probe and the collar, making the probe mounting bracket more flexible in use.
[0024] As a further improvement, the vertical height of the probe mount can be adjusted vertically relative to the probe mounting arm.
[0025] The beneficial effect is that the axial position of the probe relative to the collar can be changed at this time, which can more comprehensively complete the flaw detection of the collar.
[0026] To achieve the above objectives, the technical solution of the bearing ring flaw detection device provided by the present invention is as follows:
[0027] A bearing ring flaw detection device includes a probe and a probe mounting frame for mounting the probe. The probe mounting frame includes a horizontal arm and a probe mounting arm connected to the horizontal arm. The probe mounting arm is provided with a probe mounting seat for mounting the detection probe. The horizontal arm is provided with a clamping structure, which includes an inner clamping body for positioning and fitting against the inner wall surface of the bearing ring and an outer clamping body for positioning and fitting against the outer wall surface of the bearing ring. The horizontal arm or the clamping structure is provided with a support structure for placing on the end face of the bearing ring to support the probe mounting frame. In use, the horizontal arm can remain stationary relative to the rotation of the bearing ring.
[0028] The beneficial effects are as follows: This invention improves upon existing testing devices for flaw detection of bearing races. During testing, the probe is mounted on a probe mounting base, and the position of the cross arm is determined using a clamping structure. The cross arm is then placed at the end of the bearing race. Under the combined action of the support and clamping structures, the probe mounting bracket is stably hung on the bearing race. At this point, the rotating platform holding the bearing race can be activated, causing the bearing race and the probe mounting bracket to rotate relative to each other, achieving circumferential flaw detection. Furthermore, this invention can be flexibly mounted inside or outside the bearing race, enabling flaw detection from both the inner and outer surfaces of the bearing. The probe mounting bracket in this invention is flexible in use; compared to manually holding a probe, the position of the probe mounting bracket is relatively fixed, resulting in higher detection accuracy. It is also not limited by space and can be placed at any position on the bearing race, making it suitable for flaw detection of large bearing races.
[0029] As a further improvement, the position of at least one of the inner clamping body and the outer clamping body can be adjusted laterally relative to the cross arm to change the clamping distance between the inner clamping body and the outer clamping body.
[0030] The beneficial effect is that the clamping body has better versatility and is suitable for bearing rings with different inner and outer diameters (wall thicknesses).
[0031] As a further improvement, the positions of both the inner and outer clamping bodies can be adjusted laterally relative to the cross arm.
[0032] The advantages are: the adjustment is more flexible, allowing for more freedom in setting the probe mounting base. Furthermore, the inner and outer clamps can shift the center of gravity of the cross arm during adjustment, which helps maintain the cross arm's balance.
[0033] As a further improvement, at least one of the inner clamping body and the outer clamping body is formed by a rolling element mounted on the cross arm.
[0034] The beneficial effect is that at least one side of the contact with the collar is a rolling friction fit, which reduces friction and also avoids wear on the collar on that side caused by the clamping body.
[0035] As a further improvement, both the inner and outer clamping bodies are formed from rolling elements mounted on the cross arm.
[0036] The beneficial effect is that it ensures that neither the inner nor outer wall surfaces of the ring will be worn.
[0037] As a further improvement, the number of inner clamps is greater than the number of outer clamps.
[0038] The beneficial effect is that the inner clamp can form a more stable contact with the collar, thereby overcoming the centrifugal force of the collar when it rotates, making the probe mounting bracket more stable.
[0039] As a further improvement, the support structure is formed by rolling elements mounted on the cross arm or clamping structure.
[0040] The beneficial effect is that the friction between the cross arm or clamping structure and the end face of the collar is rolling friction, which can effectively ensure the stability of the probe mounting bracket and avoid wear on the end face of the collar.
[0041] As a further improvement, the position of the probe mounting arm can be adjusted laterally relative to the cross arm.
[0042] The beneficial effect is that it provides another way to adjust the distance between the probe and the collar, making the probe mounting bracket more flexible in use.

[0050] To address the problem that existing automated flaw detection devices are difficult to directly apply to the flaw detection of large bearing races, a fundamental technical concept of this invention is to design a probe mounting bracket that can be hung on the end face of the bearing race, and, in conjunction with the rotation of the race, achieve 360-degree flaw detection. This allows for flexible adjustment of the probe position during flaw detection, without being limited by the size of the detection device itself, making it suitable for the inspection of large bearings.
[0051] The present invention will be further described in detail below with reference to the embodiments.
[0052] Specific embodiment 1 of the bearing ring flaw detection device provided by the present invention:
[0053] The bearing ring flaw detection device provided in this embodiment includes a probe mounting bracket, such as... Figure 1 As shown, the probe mounting bracket includes a horizontal arm 3, a probe mounting arm 5, and a probe mounting base 7. The probe mounting arm 5 is connected to the horizontal arm 3, and the probe mounting base 7 is connected to the probe mounting arm 5. A probe 8 is mounted on the probe mounting base 7. The probe 8 can contact the collar 9 to be tested, thereby enabling flaw detection of the collar 9. Specifically, the probe 8 can be an ultrasonic probe or an eddy current probe. The specific detection principle is existing technology and will not be described in detail here.
[0054] In this embodiment, a clamping structure is provided on the cross arm 3. This clamping structure is used to position and fit the inner and outer walls of the collar 9, thus serving a positioning function. The clamping structure includes an inner clamping body for fitting against the inner wall of the collar 9 and an outer clamping body for fitting against the outer wall of the collar 9. Furthermore, the cross arm 3 is also provided with a support structure for supporting the collar 9. Thus, during testing, the clamping structure is axially clamped onto the collar 9, and the cross arm 3 is hooked onto the end face of the collar 9. This connects the probe mounting bracket to the collar 9, thereby determining the position of the probe 8 and ensuring its accuracy.
[0055] Furthermore, during testing, the collar 9 can rotate, and while the collar 9 rotates, the probe mounting bracket can remain relatively stationary, that is, the probe mounting bracket 9 does not rotate synchronously with the collar 9, thus achieving 360-degree circumferential testing of the collar.
[0056] Therefore, the bearing ring flaw detection device in this embodiment can be flexibly moved according to the position of the large ring, and is no longer limited to the structure of the probe mounting arm, making it suitable for large rings. Furthermore, this embodiment can be flexibly placed outside the ring 9, i.e., as shown... Figure 1 The probe 8 shown is attached to the outer wall of the collar 9, but it can also be placed inside the collar 9, i.e., the probe 8 is attached to the inner wall of the collar 9. This allows for flexible adjustment to meet the testing needs of different collars 9 without requiring a complex structure for the probe mounting base 7.
[0057] It should be noted that, in order to achieve the rotation of the collar 9, this embodiment also includes a rotating platform 10, on which three positioning blocks 11 are provided, thus realizing the rotation and support of the collar 9. However, those skilled in the art will understand that, in some embodiments, the rotating platform of other devices or equipment can be used to drive the collar 9 to rotate, such as a large vertical lathe, i.e., the lathe platform for processing the collar 9, which can also drive the collar 9 to rotate.
[0058] Specifically, such as Figure 1As shown, the clamping structure on the cross arm in this embodiment is a rolling element structure. The friction between it and the collar 9 is rolling friction, which has a small frictional force. This ensures the stability of the probe mounting bracket and prevents the clamping body from damaging the surface quality of the collar 9. In this embodiment, both the inner and outer clamping bodies are rollers, specifically the inner clamping roller 1 and the outer clamping roller 2. This ensures line contact between the rollers and the collar 9, which better protects the surface of the collar 9.
[0059] In addition, in this embodiment, the number of inner clamping rollers 1 is greater than the number of outer clamping rollers 2, specifically 2 and 1 respectively. The purpose of this is to better overcome the centrifugal force when the collar 9 rotates and ensure that the inner clamping rollers 1 have sufficient clamping effect.
[0060] Furthermore, the positions of the clamping structure, probe mounting arm 5, and probe mounting base 7 in this embodiment are all adjustable. Specifically, the lateral mounting positions of the inner clamping roller 1 and the outer clamping roller 2 relative to the cross arm 3 can be adjusted. This allows for changing the distance between the inner clamping roller 1 and the outer clamping roller 2, i.e., the clamping distance, to accommodate collars 9 with different wall thicknesses. It also allows for changing the mounting position of the clamping structure relative to the cross arm 3 to accommodate probes 8 in different positions. The lateral mounting position of the probe mounting arm 5 relative to the cross arm 3 is also adjustable, allowing for changing the position of the probe 8 relative to the collar 9 and facilitating adjustments to the detection position based on collars 9 of different sizes. The vertical position of the probe mounting base 7 relative to the probe mounting arm 5 is also adjustable, enabling detection of the probe 8 at different axial positions relative to the collar 9, thus ensuring the integrity of the detection structure.
[0061] As one implementation method for adjusting the position of the clamping structure, probe mounting arm 5, and probe mounting base 7, such as Figure 2 and Figure 3 As shown, the horizontal arm 3 is provided with a T-slot. The probe mounting arm 5 is supported and installed in the T-slot of the horizontal arm 3 by the first fastening bolt 4. Adjusting the tightness of the first fastening bolt 4 can achieve separation and locking of the probe mounting arm 5 and the horizontal arm 3. The probe mounting arm 5 is also provided with a T-slot. The probe mounting seat 7 is supported and installed in the T-slot of the probe mounting arm 5 by the second fastening bolt 6. Adjusting the tightness of the second fastening bolt 6 can achieve separation and locking of the probe mounting seat 7 and the probe mounting arm 5. This bolt locking scheme can provide a stable locking force, and also facilitates flexible movement and stepless adjustment, while maintaining low cost. The clamping structure adopts the same connection method as the horizontal arm 3, and will not be described in detail further.
[0062] The specific embodiment 2 of the bearing ring flaw detection device provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the positions of both the inner and outer clamping bodies can be adjusted relative to the horizontal arm. In this embodiment, the lateral positions of both the inner and outer clamping bodies cannot be adjusted relative to the horizontal arm, that is, the distance between the inner and outer clamping bodies is fixed, and it is still possible to detect bearing rings of a certain wall thickness.
[0063] The specific embodiment 3 of the bearing ring flaw detection device provided by this invention differs from embodiment 1 mainly in that: in embodiment 1, the positions of both the inner and outer clamping bodies can be adjusted relative to the horizontal arm. In this embodiment, one of the inner and outer clamping bodies can be adjusted relative to the horizontal arm. For example, if the inner clamping body is adjustable, the detection of bearing rings with different wall thicknesses can still be achieved. If the outer clamping body is adjustable, in conjunction with the movement of the probe mounting arm, the detection of bearing rings with different wall thicknesses can also be achieved. However, those skilled in the art will understand that the adjustable inner and outer clamping bodies can help adjust the center of gravity of the horizontal arm, thus better ensuring the balance of the probe detection device.
[0064] The specific embodiment 4 of the bearing ring flaw detection device provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, both the inner and outer clamping bodies are rolling elements formed by rollers. In this embodiment, both the inner and outer clamping bodies can be sliders, that is, the inner and outer clamping bodies and the bearing rings are subject to sliding friction. In this case, a lubricating oil film can be applied during detection to reduce friction, or an arc surface structure can be provided on the inner and outer clamping bodies to reduce the contact area between the inner and outer clamping bodies and the bearing rings.
[0065] The specific embodiment 5 of the bearing ring flaw detection device provided by this invention differs from embodiment 1 mainly in that: in embodiment 1, both the inner and outer clamping bodies are rolling elements formed by rollers. In this embodiment, only one of the inner and outer clamping bodies is a rolling element, and the other is a slider similar to that in embodiment 4, which can also perform the clamping function. Moreover, it should be noted that the rolling element is not limited to the cylindrical rollers in embodiment 1; spherical rollers are also applicable.
[0066] The specific embodiment 6 of the bearing ring flaw detection device provided by this invention differs from embodiment 1 mainly in that: in embodiment 1, the cross arm is directly attached to the end face of the ring during detection, i.e., the end face of the cross arm forms a support structure. In this embodiment, a support structure can be provided in the clamping structure, i.e., the clamping structure is directly attached to the end face of the ring. In this case, the clamping structure is not limited to the roller in embodiment 1, but can also be a slider, which can achieve the same support effect.
[0067] The specific embodiment 7 of the bearing ring flaw detection device provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the support structure formed by the end face of the cross arm contacts the end face of the ring. In this embodiment, to reduce friction, rolling elements are provided on the cross arm, and the rolling elements roll in cooperation with the ring to form a support structure. Of course, the rolling elements can be cylindrical rollers or balls.
[0068] The specific embodiment 8 of the bearing ring flaw detection device provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the position of the probe mounting arm can be adjusted relative to the horizontal arm. In this embodiment, the relative position of the probe mounting arm and the horizontal arm is fixed, and with the clamping structure being movable, the detection requirements of different bearing rings are already met.
[0069] The specific embodiment 9 of the bearing ring flaw detection device provided by this invention differs from embodiment 1 mainly in that: in embodiment 1, the position of the probe mounting base can be vertically adjusted relative to the probe mounting arm, and the probe mounting arm is a vertically extending arm. In this embodiment, the vertical position of the probe mounting base relative to the probe mounting arm is fixed and cannot be adjusted. Furthermore, the probe mounting arm does not necessarily have to be strictly vertically extended; a certain tilt angle is also acceptable.
[0070] The specific embodiment 10 of the bearing ring flaw detection device provided by the present invention differs from embodiment 1 mainly in that: in embodiment 1, the adjustable connection relationship between the cross arm, clamping structure, probe mounting base, and probe mounting arm is achieved through, as shown in... Figure 2 and Figure 3 The locking bolt shown is used for this purpose. In this embodiment, the adjustable connection between the cross arm, the clamping structure, the probe mounting base, and the probe mounting arm is achieved through another structure. For example, several pin holes are provided on the cross arm, the pin shaft is connected to the probe mounting arm, and the pin shaft cooperates with the pin hole stop of the cross arm. Adjusting the installation position of the pin shaft and different pin holes can also achieve the connection and adjustment position of the probe mounting arm.
[0071] A specific embodiment of the probe mounting bracket of the bearing ring flaw detection device of the present invention:
[0072] The embodiment of the probe mounting bracket of the bearing ring flaw detection device is the same as the probe mounting bracket in any of the embodiments 1 to 10 of the bearing ring flaw detection device described above, and will not be described in detail here.
[0073] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
