The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Please refer to Figures 1-4, the present utility model provides a technical solution: a precision bearing outer diameter polishing device, including a bottom plate 1. A placement plate 2 is fixedly connected to the top of the bottom plate 1. A placement rack 201 is fixedly connected to the top of the placement plate 2. Bearings are placed inside the placement rack 201 and stacked one by one. A first telescopic rod 202 is installed on the top of the placement plate 2. A push head 203 is provided above the placement plate 2. When the first telescopic rod 202 extends, the push head 203 is pushed to the right, and the lowermost bearing inside the placement rack 201 is pushed out and pushed above the notch on the right side of the placement plate 2. After being pushed out, the push head 203 returns, and the remaining bearings inside fall. A first motor 3 is installed on the top of the bottom plate 1. The first motor 3 is a stepping motor and rotates only a specified angle each time. Looking from above, it rotates counterclockwise by 45 degrees, and the bearing can be moved to the polishing position and polished by the polishing wheel 402. Then, it rotates by another 45 degrees, and the bearing can be moved above the conveyor belt 101. The conveyor belt 101 operates to move the bearing away. A slide rail 301 is installed on the top of the first motor 3. The slide rail 301 also rotates a specified angle each time. A second motor 302 is installed in the middle of the slide rail 301. A screw rod 303 rotates inside the slide rail 301. When the second motor 302 rotates, the screw rod 303 rotates. An upper slide bar 304 is provided on the side of the slide rail 301. The bottom of the upper slide bar 304 is rotatably connected to an upper pressing rod 305. A lower slide bar 306 is provided on the side of the slide rail 301. A third motor 307 is installed on the top of the lower slide bar 306. A lower pressing rod 308 is installed on the top of the third motor 307. When the screw rod 303 rotates, the upper slide bar 304 moves downward, and the lower slide bar 306 moves upward. The upper pressing rod 305 and the lower pressing rod 308 approach each other to clamp the bearing. When the third motor 307 rotates, the lower pressing rod 308, the bearing, and the upper pressing rod 305 can rotate together. A second telescopic rod 4 is installed on the top of the bottom plate 1. A fourth motor 401 is installed on the side of the second telescopic rod 4. The output shaft of the fourth motor 401 is installed with a polishing wheel 402. When the second telescopic rod 4 extends, the polishing wheel 402 approaches the bearing. When the fourth motor 401 rotates, the polishing wheel 402 rotates to polish the bearing.

[0021] Among them, a conveyor belt 101 is installed on the top of the bottom plate 1 to move the bearing above the conveyor belt 101. The conveyor belt 101 operates to move the bearing away. A collection box 102 is installed above the bottom plate 1. The collection box 102 is used to collect the polished bearings.

[0022] Among them, the upper slide bar 304 is threadedly connected to the upper screw rod 303, and the lower slide bar 306 is threadedly connected to the lower screw rod 303. When the screw rod 303 rotates, the upper slide bar 304 moves downward, and the lower slide bar 306 moves upward.

[0023] Among them, the screw rod 303 is installed and connected to the second motor 302. When the second motor 302 rotates, the screw rod 303 rotates.

[0024] Among them, a notch is formed on the right side of the placement plate 2. The first telescopic rod 202 extends, pushing the push head 203 to the right, and pushing out the bearing at the lowermost side inside the placement rack 201, until it is pushed above the notch on the right side of the placement plate 2. At this time, the screw rod 303 rotates, the upper slide bar 304 moves downward, the lower slide bar 306 moves upward, the upper pressing rod 305 and the lower pressing rod 308 approach each other, clamping the bearing and moving the bearing.

[0025] Among them, the push head 203 is installed and connected to the first telescopic rod 202. When the first telescopic rod 202 works, the push head 203 can be moved.

[0026] Working principle: During use, the bearings are placed inside the placement rack 201 and stacked one by one. The first telescopic rod 202 extends, pushing the push head 203 to the right, and pushing out the bearing at the lowermost side inside the placement rack 201, until it is pushed above the notch on the right side of the placement plate 2. After being pushed out, the push head 203 returns, and the remaining bearings inside fall. The second motor 302 rotates, causing the screw rod 303 to rotate, the upper slide bar 304 to move downward, the lower slide bar 306 to move upward, the upper pressing rod 305 and the lower pressing rod 308 to approach each other, clamping the bearing. The third motor 307 rotates, enabling the lower pressing rod 308, the bearing, and the upper pressing rod 305 to rotate together. Looking from above, when the third motor 307 rotates counterclockwise by 45 degrees, the bearing can be moved to the polishing position, and the rotating polishing wheel 402 approaches and polishes. The bearing itself also rotates, resulting in a better polishing effect. After polishing is completed, the third motor 307 rotates counterclockwise by 45 degrees, moving the bearing above the conveyor belt 101. The second motor 302 rotates in the reverse direction, the upper pressing rod 305 and the lower pressing rod 308 move away from each other, placing the bearing on the conveyor belt 101. The conveyor belt 101 works to move the bearing away. The third motor 307 rotates clockwise by 90 degrees, returning to the initial position, and this process repeats continuously.
