Description

Technical Field

[0001] This utility model relates to the field of bearing testing technology, and in particular to a bearing testing device that facilitates bearing testing. Background Technology

[0002] Bearings are crucial components in the machinery industry, widely used and subject to stringent requirements. The machining precision and quality of bearings directly affect the performance and lifespan of products, and directly determine the reliability of equipment and machinery. With the rapid development of modern industry, various machines have increasingly higher precision requirements for bearings. During bearing processing, it is necessary to inspect the bearing's inner diameter, inner surface, shape, and dimensions. Existing bearing inspection technologies include manual inspection, measuring instrument inspection, and sensor inspection, resulting in a wide variety of inspection equipment targeting appearance, dimensions, texture, hardness, wear, smoothness, and other aspects.

[0003] A search revealed Chinese Patent Publication No. CN221869352U, which discloses a bearing inspection device for convenient bearing testing. The device includes a clamping plate for holding and fixing the bearing, a grinding disc for effectively grinding and measuring the bearing's inner diameter, and a visual inspection camera for directly detecting the bearing's inner diameter and integrity. This allows for easy observation of any defects on the bearing's inner wall, achieving precise measurement and positioning of the bearing, thereby determining its quality.

[0004] The aforementioned bearing inspection device requires the bearing to be placed above the conveyor belt for inspection, which obstructs the bottom. This means that the visual inspection camera can only inspect a portion of the bearing area in a single inspection, requiring the bearing to be flipped multiple times to complete the inspection of the entire surface, thus affecting inspection efficiency. Therefore, a bearing inspection device that facilitates bearing inspection is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a bearing testing device for convenient bearing testing, comprising a testing frame 1. An electromagnet 2 is fixedly connected to the inner left side surface of the testing frame 1, and a magnetic cylinder 3 is inserted into the right side of the electromagnet 2. The right side surface of the electromagnet 2 is configured with a hexagonal prism structure, and the magnetic cylinder 3 is inserted into the hexagonal protrusion. When the electromagnet 2 is energized, it generates magnetic force, which magnetically limits the magnetic cylinder 3, keeping it stably positioned. When the magnetic cylinder 3 needs to be disassembled and replaced, simply stopping the electromagnet 2 releases the limit on the magnetic cylinder 3, allowing it to be directly removed. A tempered glass tube 4 is fixedly connected to the right end of the magnetic tube 3. When the magnetic tube 3 moves, it can drive the tempered glass tube 4 to move synchronously. The diameter of the inner ring of the tempered glass tube 4 is matched with the inner wall diameter of the bearing to be tested. The tempered glass tube 4 is made of transparent tempered glass, which can clearly capture images of the bearing fitted on its outer side. A limiting ring 5 is fixedly connected to the outer side of the tempered glass tube 4. The cross-section of the limiting ring 5 is set in a triangular structure. When the bearing is fitted on the outer side of the tempered glass tube 4, the limiting ring 5 can limit the bearing. At the same time, the triangular structure of the limiting ring 5 can avoid obstructing the outer wall of the bearing.

[0033] Reference Figures 3-5 The right side surface of the tempered glass tube 4 is chamfered 6, and a rubber sleeve 7 is fixedly connected to the outside of the chamfer 6. The outer surface of the rubber sleeve 7 is inclined towards the center of the right side. The chamfer 6 reduces the diameter of the right side of the tempered glass tube 4, allowing the bearing to be fitted onto the outside of the tempered glass tube 4 more quickly and easily. The rubber sleeve 7 reduces hard contact with the tempered glass tube 4, thereby reducing the risk of damage.

[0034] An internal vision inspection camera 8 is installed inside the tempered glass cylinder 4. The internal vision inspection camera 8 can visually inspect the inner surface of the bearing through the transparent inner wall of the tempered glass cylinder 4. A U-shaped frame 9 is installed above the tempered glass cylinder 4. External vision inspection cameras 10 are fixedly connected to the left, right and upper surfaces of the U-shaped frame 9. When the U-shaped frame 9 is moved to be fitted on the outside of the bearing, the three external vision inspection cameras 10 can take pictures of the left and right sides and the outer surface of the bearing. The pictures are then uploaded to an external computer and compared with qualified product pictures on the computer. This allows the external computer to inspect and judge the inner surface of the bearing ring based on the pictures. Thus, the inspection of the inner surface of the bearing ring is completed by visual inspection through electronic equipment under the action of industrial cameras.

[0035] A drive assembly 11 is provided on the outer side of the U-shaped frame 9. The drive assembly 11 includes a motor 111, which is fixedly connected to the inner right wall surface of the detection frame 1. A triangular bracket 12 is fixedly connected to the bottom of the motor 111, and the right end of the triangular bracket 12 is fixedly connected to the inner right wall surface of the detection frame 1. The triangular bracket 12 can support and limit the bottom of the motor 111, further improving the stability of the motor 111 during operation. An L-shaped connecting frame 112 is fixedly connected to the left output end of the motor 111. When the motor 111 starts, it can drive the L-shaped connecting frame 112 to rotate. A transverse electric telescopic rod 1 is fixedly connected to the inner right wall surface of the L-shaped connecting frame 112. 13. The left end of the horizontal electric telescopic rod 113 is fixedly connected to the internal vision inspection camera 8. When the horizontal electric telescopic rod 113 is started, it can drive the internal vision inspection camera 8 to move in a straight line in the left and right direction, thereby driving the internal vision inspection camera 8 to leave the interior of the tempered glass tube 4, so that the bearing can be sleeved on the outside of the tempered glass tube 4. The upper inner wall surface of the L-shaped connecting frame 112 is fixedly connected to the vertical electric telescopic rod 114. The bottom end of the vertical electric telescopic rod 114 is fixedly connected to the upper surface of the U-shaped frame 9. When the vertical electric telescopic rod 114 is started, it can drive the U-shaped frame 9 to move in a straight line up and down, thereby driving the U-shaped frame 9 to be sleeved on the outside of the bearing to be inspected.

[0036] Reference Figures 4-5An annular groove 13 is provided on the inner right side surface of the testing frame 1. A side plate 14 is fixedly connected to the left side surface of the L-shaped connecting frame 112, and a fixed rod 15 is fixedly connected to the right side surface of the side plate 14. When the L-shaped connecting frame 112 rotates, the fixed rod 15 can be driven to move synchronously through the side plate 14. A limit slider 16 is fixedly connected to the right end of the fixed rod 15. When the fixed rod 15 moves, it can drive the limit slider 16 to move synchronously. The limit slider 16 is slidably connected to the inside of the annular groove 13. The size of the annular groove 13 is the same as the rotation trajectory of the limit slider 16. The limit slider 16 rotates and slides inside the annular groove 13, which can guide and limit the movement of the L-shaped connecting frame 112 in conjunction with the fixed rod 15 and the side plate 14, so that the L-shaped connecting frame 112 can maintain stable linear movement and avoid deviation that would affect the testing of the bearing.

[0037] Working principle: The bearing to be inspected is fitted onto the outside of the tempered glass cylinder 4 through the chamfer 6. The rubber sleeve 7 prevents the bearing from colliding with the chamfer 6 and causing damage. Then, the bearing is moved to the limit ring 5 and stops moving. At this time, the bearing is directly below the U-shaped frame 9. Then, the horizontal electric telescopic rod 113 and the vertical electric telescopic rod 114 can be started simultaneously to move the internal vision inspection camera 8 into the bearing and move the U-shaped frame 9 to the outside of the bearing. At this time, the three external vision inspection cameras 10 will move to the outside of the bearing. Then, the motor 111 is started, and the internal vision inspection camera 8 and the three external vision inspection cameras 10 will rotate around the bearing through the L-shaped connecting frame 112, the horizontal electric telescopic rod 113 and the vertical electric telescopic rod 114, thereby realizing a comprehensive visual inspection of the outside of the bearing and improving the inspection efficiency.

[0038] After the inspection is completed, the horizontal electric telescopic rod 113 and the vertical electric telescopic rod 114 can be activated again to move the internal vision inspection camera 8 out of the tempered glass tube 4 and make the U-shaped frame 9 move away from the outside of the bearing. This will quickly release the limitation on bearing disassembly, allowing the bearing to be quickly disassembled from the chamfer 6. When it is necessary to inspect bearings of different diameters, the electromagnet 2 can be stopped, and the magnetic limitation on the magnetic tube 3 can be quickly released, allowing the current tempered glass tube 4 to be quickly disassembled. Then, the magnetic tube 3 corresponding to the new tempered glass tube 4 can be inserted into the right side of the electromagnet 2, and the electromagnet 2 can be activated to generate magnetic force, thus completing the replacement of the new tempered glass tube 4 to adapt to bearings of different specifications.

[0039] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
