Description

Technical Field

[0001] This utility model belongs to the field of sealing ring testing technology, and in particular relates to a bearing sealing ring inspection device. Background Technology

[0002] As one of the core components of a bearing, the dimensional accuracy of the bearing seal, especially its inner and outer diameters, directly affects the bearing's sealing performance, operational smoothness, and overall service life. Therefore, rapid and accurate dimensional inspection of the seal is a crucial step in ensuring product quality during the manufacturing process, and inspection equipment is used to test the seal.

[0003] Existing sealing ring inspection devices typically capture clear images of the sealing ring using an industrial camera. These images are then transmitted to a computer, where image processing algorithms extract the inner and outer edge contours of the sealing ring. Pixel calibration is used to calculate the actual inner and outer diameters, which are then compared to preset tolerance ranges to determine product quality. However, during use, minute camera movements, long-term vibrations of the mounting bracket leading to pose changes, or slight alterations in the camera's working distance due to mechanical wear or thermal expansion and contraction can all directly alter the magnification of the image, thus affecting imaging accuracy. Furthermore, visual inspection systems are highly dependent on external light sources. Unintentional intrusion of ambient light, as well as aging, brightness decay, or heat fluctuations caused by prolonged operation of the light source itself, can all result in uneven overall brightness and contrast in the captured images. These variations directly interfere with the image processing algorithm's determination of edge positions, leading to poor repeatability and fluctuating positioning accuracy in edge extraction. In severe cases, edge recognition may become unstable, significantly impacting the reliability and consistency of the inspection results.

[0004] To address these issues, we provide a bearing seal inspection device. Utility Model Content

[0005] The purpose of this invention is to provide a bearing seal ring inspection device. By combining the inner diameter detection clamping mechanism and the outer diameter fast detection mechanism, it solves the problem of reduced detection accuracy caused by the reliance on industrial cameras in the use of existing bearing seal ring inspection devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a bearing seal ring inspection device, comprising a base plate, a testing frame on the top of the base plate, an inner diameter testing clamping mechanism on one side of the testing frame, the inner diameter testing clamping mechanism comprising an inner diameter testing cylinder fixedly connected to one side of the testing frame, a baffle fixedly connected to the surface of the inner diameter testing cylinder, a connecting rod disposed inside the inner diameter testing cylinder, and a stop block fixedly connected to one side of the connecting rod; an outer diameter rapid inspection mechanism is provided on the top of the base plate, the outer diameter rapid inspection mechanism comprising a vertical plate fixedly connected to the top of the base plate, a hydraulic cylinder fixedly connected to one side of the vertical plate, and an outer diameter testing cylinder fixedly connected to the output end of the hydraulic cylinder.

[0008] The present invention is further configured such that the inner diameter detection clamping mechanism includes a first cylinder fixedly connected to one side of the inner diameter detection cylinder, and a compression ball fixedly connected to one side of the first cylinder.

[0009] The present invention is further configured such that the inner diameter detection clamping mechanism includes a slanted block disposed inside the inner diameter detection cylinder and a spring sleeved on the surface of the connecting rod.

[0010] The present invention is further configured such that a slider is fixedly connected to one side of the oblique block, and a groove is provided on one side of the slider.

[0011] The present invention is further configured such that a fixing plate is provided on one side of the baffle, a second cylinder is fixedly connected to one side of the fixing plate, and a push plate is fixedly connected to the output end of the second cylinder.

[0012] The present invention is further configured such that a motor is fixedly connected to the top axis of the base plate, and a support rod is fixedly connected to the bottom of the detection frame.

[0013] The present invention is further configured such that a movable block is fixedly connected to the bottom of the support rod, and a movable groove is provided at the bottom of the movable block.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting up an inner diameter detection clamping mechanism, ensures that after the sealing ring is fitted into the inner diameter detection cylinder, if its inner diameter is qualified, the inner wall of the sealing ring will fit tightly against the surface of the detection cylinder. Simultaneously, the first cylinder pushes the extrusion ball to act on the oblique cutting block, causing the connecting rod and stop block to extend and cooperate with the baffle to clamp the sealing ring. This structure integrates inner diameter detection and automatic clamping, which not only improves detection efficiency but also ensures the positional stability of the sealing ring during subsequent outer diameter detection. By setting up an outer diameter fast detection mechanism, after the sealing ring is clamped and rotated with the detection frame to the outer diameter detection station, the hydraulic cylinder pushes the outer diameter detection cylinder towards the sealing ring. If the outer diameter of the sealing ring is qualified, it can smoothly enter the outer diameter detection cylinder and fit against it. This process achieves automatic connection between inner and outer diameter detection, avoids manual intervention, and improves the consistency and reliability of detection.

[0016] 2. This utility model, by incorporating a second cylinder and a push plate, automatically sorts the sealing ring when the inner diameter fails inspection. The second cylinder drives the push plate to remove the sealing ring from the inspection station. This structure effectively reduces the labor intensity of manual sorting and improves the automation level of the production line. The inclusion of a motor, support rod, movable block, and movable groove allows the inspection frame to rotate smoothly, enabling rapid switching between the inner and outer diameter inspection stations. This rotating structure is rationally designed, operates stably, and helps improve the overall inspection speed and extend the equipment's lifespan.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] For a specific implementation example, please refer to Implementation Example 1. Figures 1-5 This utility model is a bearing seal ring inspection device, including a base plate 1, a test frame 2 on the top of the base plate 1; an inner diameter detection clamping mechanism 3 is provided on one side of the test frame 2, the inner diameter detection clamping mechanism 3 includes an inner diameter detection cylinder 31 fixedly connected to one side of the test frame 2, a baffle 32 fixedly connected to the surface of the inner diameter detection cylinder 31, a connecting rod 33 provided inside the inner diameter detection cylinder 31, and a stop block 34 fixedly connected to one side of the connecting rod 33; an outer diameter rapid inspection mechanism 4 is provided on the top of the base plate 1, the outer diameter rapid inspection mechanism 4 includes a vertical plate 41 fixedly connected to the top of the base plate 1, a hydraulic cylinder 42 fixedly connected to one side of the vertical plate 41, and an outer diameter detection cylinder 43 fixedly connected to the output end of the hydraulic cylinder 42.

[0027] Specifically, the base plate 1 has mounting holes at its top. The inspection frame 2 supports the inner diameter inspection clamping mechanism 3 and can rotate under the drive of the motor 7, realizing the conversion between the inner and outer diameter inspection stations for the sealing ring. The inner diameter inspection clamping mechanism 3 is used to inspect the inner diameter of the sealing ring and has a clamping function to facilitate subsequent outer diameter inspection. A sealing ring can be fitted onto the surface of the inner diameter inspection cylinder 31 to inspect whether the inner diameter of the sealing ring meets the standard. When it meets the standard, the sealing ring is tightly attached to the surface of the inner diameter inspection cylinder 31. Figures 1 to 4 If the standard is not met, there will be a gap between the inner diameter of the sealing ring and the surface of the inner diameter detection cylinder 31, such as... Figure 5The inner diameter measuring cylinder 31 has a movable groove on its surface that matches the stop block 34. The baffle 32 restricts the axial movement of the sealing ring to ensure that its position is fixed during the test. The connecting rod 33 connects the oblique cutting block 37 and the stop block 34 to transmit motion to clamp or release the sealing ring. After the test is qualified, the stop block 34 extends out and cooperates with the baffle 32 to clamp the sealing ring, which facilitates the subsequent outer diameter test. The outer diameter quick test mechanism 4 is used to quickly test whether the outer diameter of the sealing ring is qualified. The hydraulic cylinder 42 provides thrust to drive the outer diameter measuring cylinder 43 to move toward the sealing ring to complete the outer diameter test. The outer diameter measuring cylinder 43 serves as the reference part for the outer diameter test. If the sealing ring can enter smoothly and fit against the inner wall, the outer diameter is qualified.

[0028] For a specific embodiment two, please refer to Figures 1-5 Based on the first specific embodiment, the inner diameter detection clamping mechanism 3 further includes a first cylinder 35 fixedly connected to one side of the inner diameter detection cylinder 31, a compression ball 36 fixedly connected to one side of the first cylinder 35, an oblique cutting block 37 disposed inside the inner diameter detection cylinder 31, a spring 38 sleeved on the surface of the connecting rod 33, a slider fixedly connected to one side of the oblique cutting block 37, a sliding groove provided on one side of the slider, a fixing plate 9 provided on one side of the baffle 32, a second cylinder 5 fixedly connected to one side of the fixing plate 9, a push plate 6 fixedly connected to the output end of the second cylinder 5, a motor 7 fixedly connected to the top axis of the bottom plate 1, a support rod 8 fixedly connected to the bottom of the detection frame 2, a movable block fixedly connected to the bottom of the support rod 8, and a movable groove provided at the bottom of the movable block.

[0029] Specifically, the beveled block 37 and the extrusion ball 36 are in close contact, the beveled block 37 is fixedly connected to the connecting rod 33, one side of the spring 38 is fixedly connected to the beveled block 37, and the other side is fixedly connected to one side of the inner diameter detection cylinder 31. The size of the slide groove is adapted to the slider, and the slide groove is opened on one side of the inner diameter detection cylinder 31. The fixing plate 9 is fixedly connected to the surface of the inner diameter detection cylinder 31. The first cylinder 35 provides power to push the extrusion ball 36 to move, thereby driving the beveled block 37 and the stop block 34 to move. The extrusion ball 36 converts the linear motion of the first cylinder 35 into an axial thrust on the beveled block 37. The beveled block 37 pushes the extrusion ball 36 to move. The thrust of 6 is converted into the axial movement of the connecting rod 33, realizing the extension and retraction of the stop 34. The spring 38 provides a restoring force when the stop 34 retracts, ensuring that the stop 34 returns to its initial state. The side of the second cylinder 5 away from the fixed plate 9 passes through to the side of the baffle 32 away from the fixed plate 9 and connects with the push plate 6. The baffle 32 and the push plate 6 are in close contact, and the side of the baffle 32 and the push plate 6 away from the fixed plate 9 are flush. The second cylinder 5 drives the push plate 6 to push the unqualified sealing ring away from the inspection station, realizing automatic sorting. The output end of the motor 7 is fixedly connected to the inspection frame 2. The size of the movable slot is adapted to the movable block. The movable slot is opened on the top of the base plate 1.

[0030] The operation process of this embodiment is as follows: First, the sealing ring to be tested is placed on the surface of the inner diameter detection cylinder 31 by an external robotic arm, and its end face contacts the baffle 32. If the inner diameter of the sealing ring is qualified, its inner wall will fit tightly against the surface of the inner diameter detection cylinder 31; if it is not qualified, there will be a gap. For the sealing ring with qualified inner diameter, the first cylinder 35 is activated, pushing the extrusion ball 36 to move. The extrusion ball 36 acts on the oblique cutting block 37, and then drives the stop block 34 to extend through the connecting rod 33, which together with the baffle 32 clamps the sealing ring.

[0031] Subsequently, motor 7 starts, and guided by the support rod 8 and the movable block in the movable slot, it drives the inspection frame 2 and the clamped sealing ring to rotate to the outer diameter inspection station. Hydraulic cylinder 42 pushes the outer diameter inspection cylinder 43 towards the sealing ring. If the outer diameter of the sealing ring is qualified, it can be smoothly fitted into the outer diameter inspection cylinder 43 and fit with it; if it is not qualified, it cannot be fitted or there is a gap. For sealing rings that fail the inner and outer diameter inspection, after the inspection frame 2 rotates to the sorting station, the second cylinder 5 drives the push plate 6 to push them away, completing the automatic sorting. The whole process realizes continuous and automated inspection and sorting of the inner and outer diameters of the sealing rings. It has a reasonable structure, is easy to operate, and has high inspection efficiency, avoiding the drawbacks of using industrial cameras for inspection.
