[0002] Bearing rings are annular parts of radial rolling bearings with one or more raceways. Their manufacturing process generally includes material preparation, forging, and post-forging treatment. After the raw material is forged into a billet, the billet is forged into shape using a forging machine. After the bearing rings are forged, they need to be ground to remove excess burrs and imperfections from their surface, ensuring precision during use. However, currently, it is difficult to grind the inner and outer rings simultaneously in the curved surface grinding of bearing rings on the market. Grinding the outer ring while fixing the inner ring, and vice versa, wastes a lot of production time and affects the production rate. Utility Model Content

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1-3 As shown, this utility model is a curved surface processing device for bearing forging, including a first cylinder 1 and a motor 36. The motor 36 and the first cylinder 1 are connected by an I-shaped frame to form the motor 36 and the first cylinder 1 into a whole.

[0020] The motor 36 is equipped with a support component that supports the workpiece. The lower end of the first cylinder 1 is equipped with a pressing component and a grinding component. Under the drive of the first cylinder 1, the pressing component fixes the workpiece, while the grinding component moves down with the drive of the first cylinder 1 and fits against the inner and outer surfaces of the workpiece. Under the drive of the motor 36, the inner and outer surfaces of the workpiece are processed.

[0021] Preferably, the pressing assembly includes a first connecting rod 11, a first support ring 12, a support circular plate 13, a second connecting rod 21, a third connecting rod 22, a second support ring 23, and a first pressure ring 24; the output shaft of the first cylinder 1 is provided with a support circular plate 13, the support circular plate 13 is provided with at least two first connecting rods 11, the first connecting rods 11 are all provided with a first support ring 12, the first support ring 12 is provided with a second support ring 23 through the third connecting rod 22, and the lower end of the second support ring 23 is rotatably provided with a first pressure ring 24;

[0022] Driven by the first cylinder 1, the first support ring 12 connected to its piston rod moves downward smoothly and powerfully. As the first support ring 12 descends, it effectively drives the second support ring 23 and the first pressure ring 24 to move downward linearly in sync.

[0023] The first pressure ring 24 has a dual function in its downward movement: on the one hand, it gradually approaches and eventually forms a tight contact with the upper end face of the bearing placed in the machining position; on the other hand, as the pressure gradually increases, the first pressure ring 24, with its robust structure and precise dimensional design, firmly squeezes and fixes the bearing ring to the upper end face of the second pressure ring 31; this not only ensures the absolute stability of the bearing ring during the machining process and avoids machining errors caused by vibration or displacement, but also provides the necessary support and positioning for subsequent machining steps.

[0024] Preferably, the configuration includes a second cylinder 14, a vertical rod 15, a spring support block 16, a first spring telescopic rod 17, a support plate 19, a grinding plate 20, and a second connecting rod 21. The inner and outer walls of the first support ring 12 are each provided with a first spring telescopic rod 17. A spring support block 16 is provided on the first spring telescopic rod 17, and a vertical rod 15 passes through the spring support block 16. One of the vertical rods 15 is connected to the output end of the second cylinder 14, and the second cylinder 14 is mounted on the support circular plate 13. A support plate 19 is provided on the vertical rod 15, and a grinding plate 20 is provided on the support plate 19. The two vertical rods 15 are connected by the second connecting rod 21.

[0025] After the first pressure ring 24 securely fixes the bearing ring, the coordinated operation of the entire system does not stop; at the same time, the two grinding plates 20, as key execution components for the grinding process of the inner and outer walls of the bearing ring, also move to the inner and outer edge positions of the bearing ring under the continuous drive of the first cylinder 1.

[0026] Next, the second cylinder 14, through the extension and retraction of its piston rod, pushes the two grinding plates 20 closer to the inner and outer walls of the bearing ring in a smooth and controllable manner, ensuring that the grinding plates 20 can contact the surface of the bearing ring with the best contact angle and pressure, ensuring the uniformity and efficiency of grinding, and effectively avoiding surface damage caused by excessive pressure or improper angle.

[0027] Preferably, the support assembly includes a circular plate 3 and a second pressure ring 31; the motor 36 is provided with the circular plate 3, and the output shaft of the motor 36 extends out of the circular plate 3; the lower end of the second pressure ring 31 is closed and forms a rotary connection with the circular plate 3, and under the drive of the motor 36, the second pressure ring 31 is driven to rotate.

[0028] After the grinding plate 20 contacts the bearing ring, the second pressure ring 31 of the motor 36 rotates, thereby driving the bearing ring to rotate. During the rotation, the grinding plate 20 grinds the inner and outer walls of the bearing ring, which not only removes the minor imperfections and unevenness on the surface of the bearing ring, but also further improves its surface smoothness and precision, laying a solid foundation for subsequent assembly and use.

[0029] Preferably, the circular plate 3 is provided with at least two inclined support plates 32, each of the inclined support plates 32 is provided with a second spring telescopic rod 33, and each of the second spring telescopic rods 33 is provided with a clamping plate 34 at its opposite end; each of the clamping plates 34 is provided with a rubber pad on its opposite side, the upper end of the clamping plate 34 is bent outward, and the lower part of the clamping plate 34 is provided with a support plate 35 extending out of the clamping plate 34, and the support plate 35 and the clamping plate 34 are slidably connected;

[0030] When the bearing ring is placed, the three clamping plates 34 first pre-clamp the bearing ring to keep the center of the bearing ring and the center of the second pressure ring 31 on the same vertical line; after the bearing ring is fixed by the first pressure ring 24, since the diameter of the second support ring 23 is larger than the diameter of the first pressure ring 24, the second support ring 23 will expand the three clamping plates 34 outward, so that the three clamping plates 34 are no longer in contact with the bearing ring.

[0031] During the placement of the bearing ring, the three clamping plates 34 pre-clamp the bearing ring. The key to this step is that the bearing ring is held firmly by the appropriate pressure of the clamping plates 34, while ensuring that its center is precisely on the same vertical line as the center of the second pressure ring 31. This is not only crucial for the subsequent fixing and grinding steps, but also helps to improve the accuracy and efficiency of the entire processing.

[0032] Next, with the intervention of the first pressure ring 24, it applies a more stable fixing force to the bearing ring, ensuring that the bearing ring will not shift in position due to external interference in subsequent operations. It is worth noting that the design size of the first pressure ring 24 is smaller than the diameter of the second support ring 23. This difference plays a key role in subsequent processing steps.

[0033] Once the first pressure ring 24 successfully secures the bearing ring, the second support ring 23 begins to function. Due to its larger diameter, the second support ring 23 extends outwards with three clamping plates 34 while contacting and supporting the bearing ring, thus releasing the contact of the bearing ring and allowing subsequent processes such as grinding to proceed without interference.

[0034] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
