Description

Technical Field

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

[0002] A ball bearing is a rolling element that uses balls to maintain the separation between bearing races. The balls roll along the raceway, enabling machinery or equipment to rotate smoothly. Ball bearings are an essential component in many industries. In high-load, high-speed applications where reliability and efficiency are critical, ball bearings support rotation, reduce friction, and support radial and axial loads. Without ball bearings, many machines and equipment would not be able to operate efficiently or safely.

[0003] Ball bearings consist of an inner ring, an outer ring, balls, a cage, and seals. The inner and outer rings contact the shaft and the outer housing, respectively. The balls separate the inner and outer rings and reduce friction between the rolling elements. The cage separates the balls and maintains a uniform distance to prevent them from rubbing against each other. The seals help prevent dust, debris, and other contaminants from entering the bearing, extending the service life of the bearing system.

[0004] During bearing production, the balls need to be polished to maintain their smoothness and eliminate friction during rotation. However, existing polishing equipment cannot be adjusted to adapt to different conditions, which can lead to excessive friction between the pressing plate and the balls, hindering effective rolling polishing and even obstructing the polishing process. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a bearing ball grinding device.

[0006] The purpose of this utility model is achieved as follows: a bearing ball grinding device includes a worktable, a rotating box movably mounted on the worktable, a first servo motor mounted on the bottom of the worktable, and the output end of the first servo motor fixedly connected to the bottom end of the rotating box.

[0007] The upper end of the worktable is provided with a grinding mechanism, which includes a pressing plate. The pressing plate has irregularly shaped discs on both sides. One side of each irregularly shaped disc is connected to a transmission disc via a shaft key. The two transmission discs are connected by a transmission belt. One end of the shaft on one side is connected to the output end of the second servo motor.

[0008] Furthermore, support legs are welded to the four corners of the bottom of the workbench, a vertical plate is welded to the tail end of the workbench, and a mounting plate is welded to the top of the vertical plate.

[0009] Furthermore, a ball groove is provided between the worktable and the rotating box. The ball groove has two rings, inner and outer, and is filled with a number of balls.

[0010] Furthermore, a servo electric cylinder is fixedly mounted on the mounting plate, and a connector is fixedly provided at the upper middle end of the pressing plate. The end of the telescopic rod of the servo electric cylinder is movably connected to the connector.

[0011] Furthermore, the grinding mechanism includes a lifting plate, the second servo motor is fixedly mounted on the lifting plate, a bearing plate is welded to the other side of the lifting plate, and the shaft on one side is movably connected inside the bearing plate.

[0012] Furthermore, a fixing plate is welded to the tail end of the lifting plate, a connecting plate is welded to the top end of the fixing plate, and a limiting head is provided at the end of the connecting plate, the limiting head being movable inside the vertical plate.

[0013] Furthermore, a reinforcing plate is welded between the included angle of the upright plate and the mounting plate, a fixed frame is welded to the bottom of the workbench, the first servo motor is mounted on the upper part of the fixed frame, and a limit telescopic rod is installed between the two sides of the mounting plate and the lifting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] When in use, the first servo motor drives the rotating box to rotate, and the grinding mechanism is adapted to the rotating box so that when the bearing ball is inside the rotating box, the pressing plate can move inside the rotating box and press against the upper surface of the bearing ball to achieve grinding treatment of the surface of the bearing ball.

[0016] The grinding mechanism uses a servo electric cylinder to control the lifting and lowering of the pressing plate, making it easy to control the pressing plate to adhere to the upper surface of the bearing ball. In order to enable the pressing plate to be adjusted and controlled adaptively and to prevent the bearing ball from obstructing the rotation of the pressing plate and the rotating box, a second servo motor is installed on the lifting plate that runs synchronously with the pressing plate. The second servo motor drives the irregularly shaped discs on both sides to squeeze the pressing plate, so that one end of the pressing plate can rise and the other end can fall, which facilitates the pressing and rolling of the bearing ball and completes the grinding process of the bearing ball.

[0031] In this embodiment, preferably, a servo electric cylinder 301 is fixedly installed on the mounting plate 13, and a connector 303 is fixedly provided at the upper middle end of the pressing plate 302. The end of the telescopic rod of the servo electric cylinder 301 is movably connected to the connector 303.

[0032] It should be noted that the servo electric cylinder 301 is mounted on the mounting plate 13 to facilitate the stable installation of the grinding mechanism 3. The connection head 303 facilitates the adjustment of the pressing plate 302 and allows the pressing plate 302 to conform to the bearing balls to prevent them from becoming blocked.

[0033] In this embodiment, preferably, the grinding mechanism 3 includes a lifting plate 304, a second servo motor 305 is fixedly installed on the lifting plate 304, a bearing plate 306 is welded to the other side of the lifting plate 304, and a shaft 307 on one side is movably connected in the bearing plate 306.

[0034] It should be noted that the lifting plate 304 is designed to facilitate the installation of the second servo motor 305 and the irregularly shaped disk 310, allowing the irregularly shaped disk 310 to be positioned above the pressing plate 302. This facilitates the adaptive adjustment of the pressing plate 302, whereby the irregularly shaped disk 310 pushes the pressing plate 302 through its protruding parts. Furthermore, the irregularly shaped disks 310 on both sides are staggered, allowing the pressing plate 302 to rise at one end and descend at the other, reducing the risk of the bearing balls becoming clogged.

[0039] The specific operational procedures for this application are as follows:

[0040] When in use, the bearing balls and abrasive are placed inside the rotating box 2. Then, the servo cylinder 301 in the grinding mechanism 3 is activated, so that the servo cylinder 301 can push the pressing plate 302 to adjust its height. This allows the pressing plate 302 to move inside the rotating box 2 and fit against the upper surface of the bearing balls. Then, the first servo motor 4 is activated, so that the first servo motor 4 can drive the rotating box 2 to rotate. When the rotating box 2 rotates, the friction of the rotating box 2 is reduced by the bottom ball bearings 6, so that the rotating box 2 can achieve stable rotation.

[0041] During the polishing process, the second servo motor 305 is activated, which drives one of the irregularly shaped discs 310 to rotate. Through the transmission disc 308 and the transmission belt 309, the other irregularly shaped disc 310 is driven to rotate, so that the two irregularly shaped discs 310 are positioned above the pressing plate 302. This facilitates the adaptive adjustment of the pressing plate 302. Specifically, the irregularly shaped discs 310 push the pressing plate 302 through their protruding parts. The irregularly shaped discs 310 on both sides are staggered, which allows the pressing plate 302 to rise at one end and descend at the other end, reducing the risk of the bearing balls becoming clogged.
