Description

Technical Field

[0001] This utility model relates to the field of mechanical bearing technology, specifically to a processing equipment for angular contact ball bearings. Background Technology

[0002] As a key component in modern mechanical equipment, the performance of high-precision hydraulic equipment bearings directly affects the overall operating accuracy and stability of the equipment. Bearings are an important part of modern mechanical equipment, and their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] Application number CN202222073094.8 discloses a high-reliability precision bearing structure, relating to the field of mechanical bearing technology. It includes an outer mounting ring with an inner mounting ring inside. Bearing side covers are provided on both sides of the outer and inner mounting rings. Bearing balls are positioned between the outer and inner mounting rings. The bearing balls are limited by cages on both sides, which reduces the cage's coverage area on the bearing during use, facilitating heat dissipation between the bearing balls and the cage. Furthermore, after prolonged use, the wear of the bearing balls by the cage is located on both sides, reducing friction between the bearing balls and the outer and inner mounting rings. An outer ring seal and an inner ring seal are provided between the bearing side covers and the outer and inner mounting rings, effectively sealing the area and preventing external debris from entering between them. This also minimizes the risk of lubricant leakage from the bearing.

[0004] The aforementioned equipment installs the bearing side covers on both sides using bolts. However, during installation, workers need to align the holes on the bearing side covers with the holes on the bearings before inserting the bolts into the corresponding holes. During this process, the bearing side covers must not shift in any way. If they do shift, workers need to manually adjust them. This introduces a certain degree of instability during assembly. Furthermore, after the bearings are processed, they need to be polished. Existing polishing equipment cannot be adjusted according to the inner diameter of the bearings, resulting in limitations in the polishing device. Utility Model Content

[0005] To address the issues raised by the aforementioned equipment, which uses bolts to install bearing side covers on both sides, workers must align the holes on the bearing side covers with the holes on the bearing before inserting the bolts. During this process, the bearing side covers must not shift; any shift requires manual adjustment. This introduces instability during assembly. Furthermore, after processing, the bearings require polishing, but existing polishing equipment cannot be adjusted according to the bearing's inner diameter, limiting its effectiveness. The purpose of this invention is to provide a processing equipment for angular contact ball bearings.

The turntable rotates and fits against the upper surface of the fixed plate. A rubber pad is fixedly mounted on the side of the arc-shaped limiting block away from the sliding rod. An arc-shaped groove is formed on the turntable. A fixed rod is fixedly mounted on the upper surface of the sliding rod. The fixed rod passes through the arc-shaped groove and slides against the inner surface of the arc-shaped groove.

[0008] The bearing side cover is movably fitted to the side of the bearing body. A connecting bolt is threaded into one side of the bearing side cover, and the end of the connecting bolt is threaded into the inside of the bearing body.

There are four connecting bolts 12, and the connecting bolts 12 are arranged in a ring array on the bearing side cover 11. The multiple connecting bolts 12 can improve the stability after connection. When the bearing side cover 11 is installed on the bearing body 1, it can first be fitted onto the outside of the positioning block 21 through the positioning groove 22 opened on the bearing side cover 11. The positioning block 21 and the positioning groove 22 can limit the bearing side cover 11. Then, it can be connected by the connecting bolts 12 to facilitate positioning.

[0022] A support rod 31 is fixedly mounted on the upper surface of the fixed plate 3. A top plate 32 is fixedly mounted on the upper end of the support rod 31. An electric telescopic rod 33 is fixedly mounted on the upper surface of the top plate 32. The output end of the electric telescopic rod 33 passes through the top plate 32. A fixed shell 34 is provided at the output end of the electric telescopic rod 33. A first motor 35 is fixedly mounted inside the fixed shell 34. The output end of the first motor 35 passes through the fixed shell 34. A turntable 44 is provided at the output end of the first motor 35. An adjustable limiting component 4 is connected to the fixed plate 3.

[0023] The adjustable limiting component 4 includes a drive motor 42, which is disposed inside the fixed plate 3. A fixed plate 43 is fixedly mounted on the upper surface of the fixed plate 3. A rectangular groove 431 is formed on the outer surface of the fixed plate 43. The rectangular groove 431 has a convex cross-sectional shape. A sliding rod 432 passes through the rectangular groove 431 and slides within the rectangular groove 431. An arc-shaped limiting block 433 is fixedly mounted at the end of the sliding rod 432. The output end of the drive motor 42 passes through the fixed plate 43. A turntable 44 is fixedly fitted onto the outer surface of the drive motor 42. The turntable 44 rotates and fits against the upper surface of the fixed plate 43. An arc-shaped groove 47 is formed on the turntable 44. A fixing rod 45 is fixedly provided on the upper surface of the slide rod 432. The fixing rod 45 passes through the arc groove 47 and slides against the inner surface of the arc groove 47. Before polishing the bearing body 1, the arc-shaped limiting block 433 can be placed in the inner ring of the bearing body 1. Then, the turntable 44 can be rotated by starting the drive motor 42. The rotation of the turntable 44 through the arc groove 47 allows the slide rod 432 to slide along the arc groove 47, and the arc-shaped limiting block 433 moves outward. The rubber pad 434 contacts the inner ring of the bearing body 1, thereby limiting the bearing body 1.

The side of the arc-shaped limiting block 433 away from the sliding rod 432 is fixed with a rubber pad 434 to protect the inner ring of the bearing body 1.

[0025] Working principle: When the bearing side cover 11 is installed on the bearing body 1, the positioning groove 22 opened on the bearing side cover 11 can be sleeved on the outside of the positioning block 21. The positioning block 21 and the positioning groove 22 can limit the bearing side cover 11. Then, it can be connected by the connecting bolt 12 for easy positioning.

[0026] Before polishing the bearing body 1, the arc-shaped limiting block 433 can be placed in the inner ring of the bearing body 1. Then, the turntable 44 can be rotated by starting the drive motor 42. The rotation of the turntable 44 allows the slide rod 432 to slide along the arc-shaped groove 47, and the arc-shaped limiting block 433 moves outward. The rubber pad 434 contacts the inner ring of the bearing body 1, thereby limiting the bearing body 1. The slide rod 432, in conjunction with the rectangular slide groove 431 and the arc-shaped limiting block 433, can conveniently limit the bearing body 1 of different sizes.

[0027] By starting the first motor 35, the polishing disc 36 can be rotated. By starting the electric telescopic rod 33, the polishing disc 36 can be brought into contact with the bearing for polishing.
