[0012] Stainless steel computer lens ring finishing method, the specific steps of this method are as follows:

Subsequently, the clamping claws will automatically clamp and fix the lens ring, which is conducive to automatically clamping and fixing the lens ring, ensuring stability in subsequent processing, avoiding the need for manual operation for clamping and fixing the lens ring, which is time-consuming and reduces processing efficiency. Subsequently, after one end of the lens ring is processed, during the process of switching the processing knife, the push rod will cause the positioning ring to flip, which is conducive to automatically flipping the rotating shaft and the positioning ring when replacing the processing knife, thereby flipping the lens ring, facilitating processing of the other end of the lens ring, and avoiding the need to manually switch the other end for processing after one end of the lens ring is processed, which is time-consuming and labor-intensive and reduces processing efficiency.

[0020] 2. In the present invention, when the moving seat moves toward the chuck position, the limit block will limit the rotating shaft, and the limit block and the guide groove can enable the positioning ring to move back and forth and flip once on the moving seat. After the positioning ring flips, the limit block can guide the rotating shaft to rotate to the limit mouth position, which is conducive to the positioning plate to be completely flipped, ensuring that the end of the lens ring can still be flush with the fixed seat after flipping, avoiding the positioning ring from being unable to flip completely, resulting in the end of the lens ring being unable to be flush with the fixed seat, affecting processing, and the limit block and the guide groove can enable the positioning ring to move back and forth and flip once on the moving seat, ensuring that both ends of the lens ring can be processed by the corresponding processing knife, avoiding the two ends of the lens ring from being unable to be processed by the corresponding processing knife, resulting in collision and damage between the processing knife and the lens ring, affecting the processing progress.

[0021] 3. In the process of the sliding plate moving under the action of the moving seat of the present invention, the sliding plate will gradually move toward the side close to the chuck, the elastic telescopic tube will gradually stretch, and then the end of the support plate will move to the inside of the lens ring to support the lens ring, which is conducive to the lens ring and the support plate to form a disc, supporting the lens ring from the inside, avoiding deformation of the lens ring during the clamping process, thereby affecting the subsequent use. After one end of the lens ring is processed, the moving seat moves, and the movement of the sliding plate will drive the pulling rope to move together. The pulling rope will pull the elastic telescopic tube to contract, and the clamping claw will release the clamping of the lens ring. Then the support plate will move out of the lens ring, and then the positioning ring will flip over, and the elastic telescopic tube will not affect the flipping of the positioning ring.

[0039] When processing the stainless steel computer lens ring, it is necessary to first place the lens ring in the middle position of multiple positioning blocks 7, and then press the lens ring, the lens ring will squeeze the positioning block 7 to move to the outside of the positioning ring 6, when the lens ring is fitted with the positioning ring 6, release the lens ring, and the multiple positioning blocks 7 will push the lens ring to the middle position of the positioning ring 6 and clamp the lens ring, which is conducive to quickly positioning and clamping the lens ring, and does not require manual disassembly of the clamping tool, reducing the time used for positioning, simplifying manual operation, and avoiding the use of clamping devices that need to be disassembled. Disassembly is required for each installation, which is cumbersome, time-consuming and labor-intensive, and reduces processing efficiency. Then start the processing device, and move the movable seat 2 to the position of the chuck 4.

Then, when the moving seat 2 moves again,The clamping claw 8 will clamp and fix the lens ring again, the chuck 4 will rotate, and the processing knife 3 will process the other end of the lens ring;

[0040] During the rotation of the positioning ring 6, it is difficult for the push rod 21 to act on the toggle rod 22 to make the positioning ring 6 just flip to the other side. As a further solution of the present invention, a U-shaped limit block 23 is elastically and slidably connected to the surface of the fixed seat 5 corresponding to the position of the rotating shaft 19. The two sides of the inner part of the limit block 23 are inclined surfaces. A limit opening 24 is opened on the surface of the rotating shaft 19 corresponding to the position of the limit block 23.

The end of the support plate 29 away from the elastic telescopic tube 28 can move to the inside of the lens ring. A plurality of pulling ropes 30 are fixedly connected to the surface of the end of the support plate 29 close to the elastic telescopic tube 28. The pulling ropes 30 extend to the elastic telescopic tube 28 and then penetrate the elastic telescopic tube 28 and the fixing seat 5, and are fixedly connected to the tail of the sliding plate 9. The movement of the plurality of sliding plates 9 can drive the elastic telescopic tube 28 to contract. During the movement of the sliding plate 9 by the moving seat 2, the sliding plate 9 will gradually move toward the side close to the chuck 4, the elastic telescopic tube 28 will gradually extend, and then the end of the support plate 29 will move to the inside of the lens ring to support the lens ring, which is conducive to the lens ring and the support plate 29 to form a disc, supporting the lens ring from the inside to avoid deformation of the lens ring during the clamping process, thereby affecting subsequent use. After the processing of one end of the lens ring is completed, the moving seat 2 moves, and the movement of the sliding plate 9 will drive the pulling rope 30 to move together.
