Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] refer to Figure 1 As shown, this quasi-center polishing device of the present invention includes a support component 10, a first direction driving component 20 mounted on the support component 10, a second direction driving component 30 arranged along one direction of the first direction driving component 20, a third direction driving component 40 arranged along another direction of the second direction driving component 30, and a quasi-center polishing component 50 arranged on one side of the third direction driving component 40. Wherein, the aforementioned one direction is... Figure 1 The Y-axis direction, the other direction mentioned above is Figure 1 The Z-axis direction in the equation.

[0024] refer to Figure 2 As shown, the first directional drive assembly 20 includes a support frame 201, a first ball screw 204 below the support frame 201, a first slider 205 on the first ball screw 204, the first slider 205 connected to the support frame 201, and a second directional drive assembly 30 connected above the support frame 201. A first belt 203 is provided on one side of the first ball screw 204, and the first belt 203 is connected to a first drive motor 202. The first drive motor 202 provides power, which is transmitted through the first belt 203 to make the first ball screw 204 roll, thereby causing the second directional drive assembly 30 connected to the first slider 205 to move on the first ball screw 204, for adjusting the front-to-back distance between the quasi-ball center polishing component 50 and the workpiece.

[0025] Refer again Figure 1 , Figure 3As shown, the second direction drive assembly 30 includes a second ball screw 303, a second slider 304 on the second ball screw 303, and a third direction drive assembly 40 fixedly connected to the second slider 304. A second belt 302 is provided on one side of the second ball screw 303, and the second belt 302 is connected to the second drive motor 301. Under the driving action of the second drive motor 301, the second belt 302 drives the second slider 302 to move on the second ball screw 303.

[0026] refer to Figure 4 As shown, the third-direction drive assembly 40 includes a third ball screw 403, a third belt 402 on one side of the third ball screw 403, and the third ball screw 403 connected to one side of the third belt 402. A third slider 404 is provided on the third ball screw 403, and a quasi-spherical polishing component 50 is fixedly connected to the third slider 404. Under the driving action of the third drive motor 401, the third ball screw 403 rolls, thereby causing the third slider 402 to move on the third ball screw 403.

[0027] Refer again Figure 4 As shown, the quasi-center polishing component 50 includes a servo motor 501, a fourth belt 502 on one side of the servo motor 501, a bushing 503 on one side of the fourth belt 502, a main shaft 504 connected to one side of the bushing 503, and a bearing 505 on the main shaft 504. The bushing 503 has a slot 508, and a connecting block 507 is connected to the main shaft 504. The connecting block 507 is fixedly connected to a third-party directional drive component 40, and a quasi-center polishing head 506 is located at the bottom of the main shaft 504. Under the drive of the servo motor 501, the fourth belt 502 connected to the servo motor 501 drives the main shaft 504 to rotate at high speed. Since the third-party directional drive component 40 is fixedly connected to the connecting block 507, and the connecting block 507 is connected to the quasi-center polishing component 50, the main shaft 504 moves up and down along the slot 508 under the drive of the third-party directional drive component 40. The outer wall of the quasi-spherical polishing head, 506-1, is made of thin-walled metal with excellent ductility, making it suitable for most spherical parts on the market. The inner wall of the quasi-spherical polishing head, 506-2, is made of sandpaper, which allows for all-around grinding and polishing of the spherical parts being processed.

[0028] In this embodiment, the working principle of the quasi-spherical center polishing device is as follows: The operator starts the first drive motor 202, and the first belt 203 transmits power to move the first slider 205 on the first ball screw 204. Since the first slider 205 is fixedly connected to the second drive assembly 30, it drives the second drive assembly 30 to move. The second drive motor 301 is then started, and the second slider 304 moves on the second ball screw 303 under the drive of the second drive motor 301. At this time, since the second slider 304 is connected to the third drive assembly 40, the third drive assembly 40 moves along with the second slider 304. The third drive motor 401 is then started, and the power transmitted by the third belt 402 causes the third ball screw 403 to roll, thereby synchronously driving the third slider 404 to move on the third ball screw 403. The third slider 404 is fixedly connected to the quasi-spherical center polishing component 50, thereby causing the quasi-spherical center polishing head 506 to move up and down along the groove 508. At the same time, the servo motor 501 outputs power, and the fourth belt 502 drives the quasi-spherical polishing head 506 to rotate at high speed, thereby polishing the spherical parts being processed from all directions.

In short, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
