Technical Field

[0001] This application relates to the field of surface oxidation treatment technology, and in particular to an apparatus for immersion surface oxidation treatment of bearing rings. Background Technology

[0002] Immersion oxidation treatment of bearings is a commonly used surface treatment method, mainly used to remove oxide layers, rust and impurities from the bearing surface, improve the surface quality of the bearing, and provide a good foundation for subsequent coating, chrome plating and other processes.

[0003] Using a large oxidation tank during the oxidation treatment of large bearing surfaces would increase costs and require additional transfer equipment to handle multiple processes. Therefore, a low-cost large bearing surface oxidation treatment device is needed. Summary of the Invention

The device uses a large bearing to rotate for immersion, eliminating the need for a large oxidation tank, thus reducing costs. At the same time, it can be quickly transferred to other processes, improving efficiency.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] An immersion surface oxidation treatment device for bearing rings includes a lifting base, a connector, a mounting plate, a bearing housing, a support shaft, a rotating wheel, a rotating ring, a telescopic rod, and a nut. The mounting plate is located below the lifting base, and both ends of the connector are fixedly connected to the lifting base and the mounting plate, respectively. The bearing housing is fixedly installed at the bottom of the mounting plate. The support shaft is located on the inner side of the bearing on the bearing housing and is connected to a drive assembly capable of driving its rotation. There are two rotating wheels, which are fixedly connected to both ends of the support shaft, respectively. The rotating ring is fixedly connected to the rotating wheel.

[0021] like Figure 1-4 As shown, a surface oxidation treatment device for immersion of bearing rings includes a lifting base 1, a connecting piece 2, a mounting plate 3, a bearing seat 4, a support shaft 5, a rotating wheel 6, a rotating ring 7, a telescopic rod 9, and a nut 10. The mounting plate 3 is located below the lifting base 1, and the two ends of the connecting piece 2 are fixedly connected to the lifting base 1 and the mounting plate 3 respectively. The bearing seat 4 is fixedly installed at the bottom of the mounting plate 3. The support shaft 5 is located on the inner side of the bearing on the bearing seat 4, and the support shaft 5 is connected to a drive assembly that can drive its rotation. There are two rotating wheels 6, which are fixedly connected to the two ends of the support shaft 5 respectively. The rotating ring 7 is fixedly connected to the rotating wheel 6. There are multiple sets of telescopic rods 9, which are evenly arranged in a ring around the support shaft 5 along the edge of the rotating ring 7 to securely support the bearing ring. The telescopic rods 9 pass through the rotating ring 7 to move radially along the support shaft 5. Nuts 10 are provided on the telescopic rods 9 for securing them.

[0022] Specifically, the hoisting base 1 is hoisted, and the hoisting support bearing seat 4 and the support shaft 5 are connected by the connecting piece 2. The support shaft 5 is driven to rotate so that the rotating wheels 6 and the rotating rings 7 at both ends of the support shaft 5 rotate and are then fastened to the telescopic rod 9. Multiple sets of telescopic rods 9 support the inner side of the bearing ring to support the bearing ring to be coaxial with the support shaft 5. Then, the bearing ring is driven to rotate so that the bearing ring is gradually immersed in the surface oxidation treatment.

[0023] Furthermore, the drive assembly includes a first shaft seat 13, a first sprocket 14, a motor 15, a second shaft seat 16, a second sprocket 17, a first chain 18, a third sprocket 19, a fourth sprocket 20, a third shaft seat 21, a second chain 22, a fifth sprocket 23, a sixth sprocket 24, and a third chain 25. The first shaft seat 13, the motor 15, and the second shaft seat 16 are all fixedly mounted on the lifting base 1. The output end of the motor 15 is connected to the shaft of the first shaft seat 13, and the first sprocket 14 is fixedly mounted on the shaft of the first shaft seat 13, while the second sprocket 17 is fixedly mounted on the shaft of the second shaft seat 16. The first chain 18 drives the first sprocket 14 and the second sprocket 17. The third sprocket 19 is spaced apart from the second sprocket 17 and is mounted on the shaft of the second shaft seat 16. The third shaft seat 21 is fixed on the connector 2 or the mounting plate 3. The fourth sprocket 20 is fixedly mounted on the shaft of the third shaft seat 21. The second chain 22 drives the third sprocket 19 and the fourth sprocket 20. The fifth sprocket 23 is spaced apart from the fourth sprocket 20 and is mounted on the shaft of the third shaft seat 21. The sixth sprocket 24 is fixedly mounted on the support shaft 5. The third chain 25 drives the fifth sprocket 23 and the sixth sprocket 24.

[0024] Specifically, the first sprocket 13 is fixedly mounted on the hoisting base 1. When the motor 15 drives the first sprocket 14 to rotate, the first sprocket 14 meshes with the first chain 18, and the first chain 18 synchronously drives the second sprocket 17 to rotate. After the second sprocket 17 rotates, it synchronously causes the shaft to rotate, and then the third sprocket 19 rotates. The third sprocket 19 drives the fourth sprocket 20 to rotate through the second chain 22, and then the shaft synchronously drives the fifth sprocket 23 to rotate. Then the fifth sprocket 23 meshes with the third chain 25, and through the third chain 25, it synchronously causes the sixth sprocket 24 to rotate. Finally, the sixth sprocket 24 drives the support shaft 5 to rotate, which causes the bearing ring to rotate and gradually undergo oxidation treatment.

[0025] Furthermore, the rotating ring 7 is ring-shaped, and the rotating ring 7 is coaxial with the support shaft 5 to maintain the stability of the bearing ring rotation.

[0026] Furthermore, the telescopic rod 9 is arranged radially along the support shaft 5 along its length direction, and a limiting block 11 is fixedly connected to the outward end of the telescopic rod 9, with a limiting groove 12 provided on the limiting block 11.

[0027] Specifically, by installing at least three telescopic rods 9 on the mounting plate, the bearing ring can be supported from multiple directions to prevent it from falling off. At the same time, the bearing ring is kept coaxial with the support shaft 5 to ensure stable rotation. The concave and convex parts on the bearing ring can be inserted into the inner side of the limiting groove 12 to further prevent the bearing ring from falling off.

[0028] Furthermore, the nuts 10 consist of two nuts that are screwed onto the telescopic rod 9, and a washer 8 that is fixedly connected to the rotating ring 7 is provided between the two nuts.

[0029] Specifically, the position of the nut 10 on the telescopic rod 9 is adjusted by turning it, thereby adjusting the telescopic rod 9's extension and retraction, which facilitates the tightening of the bearing ring.

[0030] In the above structure, the bearing ring to be processed is placed on the limiting block 11. The telescopic rod 9 can move radially to adapt to the diameter of the bearing ring. The telescopic rod 9 is tightened by screwing the nut 10 to fix the bearing ring. The motor 15 is powered to drive the first sprocket 14 to rotate. The first sprocket 14 drives the second sprocket 17 to rotate through the first chain 18, and then the third sprocket 19 to rotate. Then the second chain 22 drives the fourth sprocket 20 to rotate, and then the fifth sprocket 23 to rotate. After the fifth sprocket 23 rotates, it drives the sixth sprocket 24 to rotate through the third chain 25. Finally, the support shaft 5 rotates, so that the rotating wheel 6 and the rotating ring 7 rotate synchronously. Then the bearing rotates, gradually immersing the bearing for surface oxidation treatment.

Those skilled in the art should understand that this application is not limited to the above embodiments.
