[0002] Bearings, as indispensable key components in mechanical equipment, play a vital role in various industrial production scenarios. They are widely used in many fields such as automobile manufacturing, aerospace, energy and power, and precision instruments, undertaking the important tasks of supporting rotating mechanical bodies, reducing the coefficient of friction during their movement, and ensuring their rotational accuracy. The quality of bearings directly affects the operating performance, stability, and service life of the entire mechanical equipment.
[0003] Bearing quality inspection utilizes visual inspection technology based on computer vision and image processing principles. By simulating the human visual system, it acquires bearing images using image acquisition equipment, and then uses computer software to analyze and process the images, thereby enabling the inspection of bearing quality.
[0004] In the bearing fixing process, existing testing devices mostly adopt a single clamping method, which only clamps the outer ring of the bearing with jaws or only relies on the inner ring for support. The fixing method is prone to bearing shaking or displacement during the testing process. In addition, the existing testing devices lack flexibility in structural design, cannot achieve full rotation of the bearing, and are not convenient for comprehensive testing of all surfaces of the bearing. Therefore, this utility model provides a bearing quality testing device. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a bearing quality inspection device that solves the problems of bearing shaking or displacement during inspection caused by simply clamping the outer ring of the bearing with jaws or relying solely on the inner ring for support, as well as the lack of flexibility in the structural design of existing inspection devices, which prevents the bearing from rotating in all directions and makes it inconvenient to conduct comprehensive inspection of all surfaces of the bearing.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing quality inspection device, comprising a mounting base, wherein the mounting base is provided with a mounting mechanism for bearing quality inspection, the mounting mechanism comprising:
[0007] The adjustment component includes a detection platform fixed to the upper surface of the mounting base, a support plate connected to the upper surface of the detection platform via a drive component, and a mounting cylinder connected to the support plate via a gear component inside the support plate.
[0008] The clamping assembly includes a cavity groove inside the mounting cylinder, a clamping plate connected by a telescopic assembly inside the cavity groove, a mounting block fixed inside the cavity groove, and a pair of second electric push rods fixed inside the mounting block. The telescopic ends of the second electric push rods are fixed with L-shaped brackets.
[0009] Preferably, the driving component includes a first motor fixed to the upper surface of the detection platform, a support shaft fixed to the output end of the first motor, a support plate fixedly connected to the outer wall of the support shaft, and a limiting block for supporting the support plate fixed at the edge of the upper surface of the detection platform.
[0010] Preferably, the gear assembly includes a fixed bracket fixed to the side wall of the support plate, a second motor fixed inside the fixed bracket, a small gear fixed to the output end of the second motor, a mounting cylinder rotatably connected through the inside of the support plate, and a large gear meshing with the small gear fixed to the outer wall of the mounting cylinder.
[0011] Preferably, the telescopic assembly includes a first electric push rod that is fixed through one end inside the cavity groove, a sliding plate that is fixed to the telescopic end of the first electric push rod, a clamping plate that is fixedly connected to the four ends of the sliding plate, and four sets of guide grooves for the clamping plate to slide through the outer wall of the mounting cylinder.
[0012] Preferably, a pair of fixing plates are fixed to the upper end face of the mounting base, a pair of sliding rods are fixed to the inner wall of the fixing plates, a detection bracket is slidably connected to the outer wall of the sliding rods, and a screw is rotatably connected to the inner wall of the fixing plates between the sliding rods, and the screw is threadedly connected to the detection bracket.
[0013] Preferably, a detection probe is provided at the upper end of the detection bracket, and an illumination lamp is provided on the inner wall of the detection bracket.
[0014] Beneficial effects
[0015] This invention provides a bearing quality inspection device. Compared with the prior art, it has the following advantages:
[0016] Firstly, this utility model uses an L-shaped bracket and a clamping plate to clamp the bearing. The L-shaped bracket supports the inner side of the bearing, while the clamping plate clamps it from the other side. This dual clamping method effectively fixes the bearing and prevents it from shaking or shifting during the testing process, thus ensuring the accuracy and reliability of the test.
[0017] Secondly, this utility model starts the first motor, the output end of the first motor drives the support shaft to rotate, the support shaft drives the support plate to rotate. Since there is a limiting block fixed at the edge of the upper end face of the detection platform to support the support plate, the rotation range of the support plate is limited. The rotation range of the first motor is 90°, which can rotate the mounting cylinder on the support plate to the vertical direction so as to carry out the inspection work on the bearing surface. Then, the second motor is started, the output end of the second motor drives the pinion to rotate. Since there is a large gear fixed on the outer wall of the mounting cylinder that meshes with the pinion, and the mounting cylinder passes through the inside of the support plate for rotational connection, the pinion will drive the large gear to rotate, thereby driving the mounting cylinder to rotate, so that the clamped and fixed bearing will rotate accordingly, so as to carry out comprehensive inspection of all surfaces of the bearing.

[0023] 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.
[0024] Please see Figures 1-4This utility model provides a technical solution: a bearing quality testing device, including a mounting base 1, characterized in that: the mounting base 1 is provided with a mounting mechanism for bearing quality testing, the mounting mechanism including:
[0025] The adjustment component includes a detection platform 2 fixed on the upper surface of the mounting base 1, a support plate 203 connected by a drive component on the upper surface of the detection platform 2, and a mounting cylinder 204 connected by a gear component inside the support plate 203.
[0026] The clamping assembly includes a cavity groove 4 inside the mounting cylinder 204. A clamping plate 403 connected by a telescopic assembly is provided inside the cavity groove 4. A mounting block 5 is fixed inside the cavity groove 4. A pair of second electric push rods 501 are fixed inside the mounting block 5. An L-shaped bracket 502 is fixed to the telescopic end of the second electric push rods 501.
[0027] In a preferred embodiment, the telescopic assembly includes a first electric push rod 401 fixed through one end of the cavity groove 4. A sliding plate 402 is fixed to the telescopic end of the first electric push rod 401. A clamping plate 403 is fixedly connected to the four ends of the sliding plate 402. The outer wall of the mounting cylinder 204 is provided with four sets of guide grooves 404 for sliding of the clamping plate 403. When installing the bearing, the L-shaped brackets 502 on both sides of the mounting cylinder 204 retract into the cavity groove 4, and the bearing is inserted into the outer wall of the mounting cylinder 204. The inner side of the bearing is in the position of the L-shaped bracket 502. Then, the L-shaped brackets 502 on both sides extend outward from the outside of the mounting cylinder 204 through the second electric push rod 501 to support the inner side of the bearing. Then, the clamping plate 403 telescopically extends and retracts under the action of the first electric push rod 401 through the sliding plate 402. The clamping plate 403 is located on the other side of the L-shaped bracket 502. When the clamping plate 403 telescopically extends and retracts, it cooperates with the L-shaped bracket 502 to clamp and fix the bearing.
[0028] With the L-shaped bracket 502 and the clamping plate 403 working together, the L-shaped bracket 502 supports the inner side of the bearing, while the clamping plate 403 clamps it from the other side. This dual clamping method effectively fixes the bearing, preventing it from shaking or shifting during the testing process, thus ensuring the accuracy and reliability of the test.
[0029] In a preferred embodiment, the drive assembly includes a first motor 201 fixed to the upper surface of the detection platform 2, a support shaft 202 fixed to the output end of the first motor 201, a support plate 203 fixedly connected to the outer wall of the support shaft 202, a limiting block 205 fixed at the edge of the upper surface of the detection platform 2 for supporting the support plate 203, and a gear assembly including a fixed bracket 3 fixed to the side wall of the support plate 203, a second motor 301 fixed inside the fixed bracket 3, a pinion 302 fixed to the output end of the second motor 301, and a mounting cylinder 204 rotatably connected through the inside of the support plate 203. A large gear 303 meshing with the pinion 302 is fixed to the outer wall of the mounting cylinder 204. The rotation range of the first motor 201 is 90°, rotating the mounting cylinder 204 on the support plate 203 to the vertical direction, thereby performing the detection work on the bearing surface.
[0030] Specifically, the first motor 201 is started, and its output drives the support shaft 202 to rotate. The support shaft 202 then drives the support plate 203 to rotate. Because a limiting block 205 is fixed at the edge of the upper surface of the detection platform 2 to support the support plate 203, the rotation range of the support plate 203 is limited. The rotation range of the first motor 201 is 90°, which allows the mounting cylinder 204 on the support plate 203 to be rotated to a vertical position for bearing surface inspection. Then, the second motor 301 is started. The output end of motor 301 drives the pinion 302 to rotate. Since the outer wall of the mounting cylinder 204 is fixed with a large gear 303 that meshes with the pinion 302, and the mounting cylinder 204 passes through the inside of the support plate 203 for rotational connection, the pinion 302 will drive the large gear 303 to rotate, thereby driving the mounting cylinder 204 to rotate, so that the clamped and fixed bearing will rotate accordingly, so as to perform comprehensive inspection on all surfaces of the bearing. The second motor 301 has a rotation range of 360°, and the motor model is N30-050.
[0031] The first motor 201 drives the support plate 203 to rotate, which can adjust the mounting cylinder 204 to a vertical position, making it convenient to inspect the bearing surface. The second motor 301 drives the mounting cylinder 204 to rotate through the gear assembly, so that the bearing can rotate evenly. The inspection probe 603 can perform comprehensive inspection on all surfaces of the bearing.
[0032] In a preferred embodiment, a pair of fixing plates 6 are fixed to the upper end face of the mounting base 1, a pair of sliding rods 601 are fixed to the inner wall of the fixing plates 6, a detection bracket 602 is slidably connected to the outer wall of the sliding rods 601, a screw is rotatably connected to the inner wall of the fixing plates 6 between the sliding rods 601, and the screw is threadedly connected to the detection bracket 602. A detection probe 603 is provided at the upper end of the detection bracket 602, and an illumination lamp 604 is provided on the inner wall of the detection bracket 602.
[0033] By rotating the screw located between the slide rods 601 on the inner wall of the fixing plate 6, since the screw is threadedly connected to the detection bracket 602 and the detection bracket 602 is slidably connected to the outer wall of the slide rod 601, the rotation of the screw will cause the detection bracket 602 to slide on the slide rod 601, thereby adjusting the position of the detection probe 603 so that it is close to the bearing surface for detection. The lighting lamp 604 set on the inner wall of the detection bracket 602 provides sufficient light for detection, ensuring that the detection probe 603 can clearly obtain information from the bearing surface.
[0034] The specific working principle of the detection is explained in detail in CN202510221809.5, "An Automatic Detection System for Bearing Surface Defects Based on Image Recognition," and will not be elaborated further.
[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0036] During operation, when installing the bearing, first retract the L-shaped brackets 502 on both sides of the mounting cylinder 204 into the cavity groove 4, insert the bearing into the outer wall of the mounting cylinder 204, so that the inner side of the bearing is in the position of the L-shaped bracket 502. Then, activate the second electric push rod 501, and its telescopic end extends to drive the L-shaped bracket 502 to extend out of the outside of the mounting cylinder 204 and open, supporting the inner side of the bearing. After that, activate the first electric push rod 401, and its telescopic end extends to push the slide plate 402 to slide in the cavity groove 4. Since the clamping plate 403 is fixedly connected to the four ends of the slide plate 402 and can slide in the guide groove 404 on the outer wall of the mounting cylinder 204, the clamping plate 403 moves with the slide plate 402, and cooperates with the L-shaped bracket 502 to clamp and fix the bearing.
[0037] At the start of the test, the first motor 201 is activated, and its output drives the support shaft 202 to rotate. The support shaft 202 drives the support plate 203 to rotate. Because the limiting block 205 at the edge of the upper surface of the test platform 2 restricts the rotation range of the support plate 203, after the first motor 201 rotates 90°, the mounting cylinder 204 on the support plate 203 is rotated to the vertical direction. Then, the second motor 301 is activated, and its output drives the pinion 302 to rotate. Because the large gear 303 on the outer wall of the mounting cylinder 204 meshes with the pinion 302 and the mounting cylinder 204 passes through the support plate 203 for rotational connection, the pinion 302... 02 drives the large gear 303 to rotate, which in turn drives the mounting cylinder 204 to rotate, causing the clamped and fixed bearing to rotate evenly. Finally, the screw located between the slide rods 601 on the inner wall of the fixing plate 6 is rotated. Since the screw is threadedly connected to the detection bracket 602 and the detection bracket 602 is slidably connected to the outer wall of the slide rod 601, the rotation of the screw causes the detection bracket 602 to slide on the slide rod 601, adjusting the position of the detection probe 603 to be close to the bearing surface for detection. At the same time, the lighting lamp 604 on the inner wall of the detection bracket 602 provides sufficient light for detection, ensuring that the detection probe 603 can clearly obtain the bearing surface information.
