[0002] A fixture is a device used to secure a workpiece during mechanical manufacturing, positioning it in the correct position for construction or testing. Broadly speaking, any device used to quickly, conveniently, and safely secure a workpiece during any process can be called a fixture. Polishing is a crucial step in the manufacturing of optical lenses, and prior to polishing, the lens must be secured to a fixture.

[0003] An existing Chinese patent (publication number CN214024975U) discloses a rotating optical lens fixture, comprising a main body, a plurality of support columns welded to the top of the main body, and a clamping mechanism connected to the inner side of the support columns, a motor installed inside the main body, and a rotating disk extending to the outer side of the top of the main body is provided at the output end of the motor. By providing a pressing plate, a baffle, a rotating plate and a collection frame, after the lens is polished, the pressing plate is pressed to contact the sealed frame, and at the same time, the bottom end of the pressing plate pushes the rotating plate to rotate around the rotating seat, and the debris generated during the lens polishing blocked by the inner side of the baffle falls into the interior of the collection frame, and the collection frame is taken out by manually opening the rotating door on one side of the main body, thereby processing the collection frame, and then blocking and collecting the debris generated by the lens polishing, thereby protecting the working environment better and protecting the health of the staff;

[0004] However, in actual use, only the clamps on both sides clamp the optical lens. When the grinding component is grinding, only the two ends of the optical lens are clamped and fixed. Since the friction generated by the grinding component on the optical lens is large, it is easy to cause the optical lens to shake, affecting the grinding effect. In addition, the contact area between the clamp and the optical lens is small, resulting in low stability of the lens when clamped. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 The utility model provides a technical solution: it includes a frame 1 and a grinding component 2 connected to the top of the inner wall of the frame 1, a servo motor 14 is fixedly installed on the bottom of the outer wall of the frame 1, and a rotating shaft 5 is rotatably connected to the servo motor 14. A rotating bracket 4 is fixedly installed on the top of the rotating shaft 5, and a driving gear 8 is rotatably connected to the rotating bracket 4. The driving motor 9 that rotates the driving gear 8 is connected to the rotating bracket 4, and one side of the driving gear 8 is meshed with a transmission gear 10, and the top of the transmission gear 10 is fixedly connected with a suction cup 11.

The limiting column 13 is slidably connected in the arc groove 12, and the side of the moving rod 6 away from the transmission gear 10 is fixedly connected with an arc plate 7.

[0024] During specific implementation, when the polishing component 2 in the frame 1 is used to polish the optical lens, the optical lens is placed on the upper part of the suction cup 11, and then the drive motor 9 is started. The drive motor 9 drives the drive gear 8 coaxially connected to it to start rotating. When the drive gear 8 rotates counterclockwise, the transmission gear 10 meshing with the drive gear 8 rotates clockwise. When the transmission gear 10 rotates, the limit column 13 slides on the transmission gear 10 along the arc groove 12 opened on it, and the moving rod 6 fixedly connected to the limit column 13 moves inward in the groove opened in the rotating bracket 4. The arc plate 7 fixedly connected to the moving rod 6 realizes the clamping of the optical lens during the synchronous movement with the moving rod 6.

[0025] It should be noted that the grinding component 2 is rotatably connected to the top of the frame 1 and can be moved up and down by a rotating assembly. The movement of the upper grinding component 2 is a prior art and should be known to those skilled in the art, so no further explanation will be given here.

[0026] For further information, see Figure 1 The top of the frame 1 is movably connected with a water washing pipe 3. There are two water washing pipes 3, which are respectively located on both sides of the top of the frame 1. The positions of the water washing pipes 3 correspond to the suction cups 11.

[0027] In specific implementation, water washing pipes 3 are set on both sides of the top of the frame 1 to clean the debris generated during the lens grinding process. During the grinding process, pure water flows from the outside of the frame 1 through the water washing pipes 3 to the optical lens, flushing the grinding debris to achieve the cleaning effect of the lens.

[0028] For further information, see Figure 1 The shape of the rotating bracket 4 is a "cross shape", the rotating bracket 4 is connected to a short-circuit board, and the driving motor 9 is connected to the short-circuit board.

[0029] During specific implementation, in order to improve the stability of clamping the lens, the shape of the rotating bracket 4 is set to a "cross shape" to achieve a four-sided clamping effect, and one end of the rotating bracket 4 is set to an arc shape to facilitate the installation of the driving gear 8 and the driving motor 9 that drives the driving gear 8 to rotate.

[0030] For further information, see Figure 3 There are four arc-shaped slots 12 , and the arc-shaped slots 12 are arc-shaped and are evenly spaced and distributed in a circular array around the center of the transmission gear 10 .

[0031] In a specific implementation, an arc groove 12 is provided on the transmission gear 10 and is evenly spaced in a circular array with the center of the transmission gear 10, so that when the limiting column 13 slides in the arc groove 12, the moving rod 6 fixedly connected to the limiting column 13 can move stably.

[0032] For further information, see Figure 1 Water outlets 16 are provided at the bottom of both sides of the frame 1, and a filter screen 15 is connected to the water outlet 16.

[0033] During specific implementation, a water outlet 16 is provided to discharge pure water flowing out of the water washing pipe 3 to prevent water from accumulating in the frame 1 and affecting the grinding of the grinding component 2. A filter screen 15 is provided to filter the grinding debris and fix the debris on the filter screen 15 to prevent the debris from flowing out and being difficult to clean.

[0034] For further information, see Figure 1 , fixed plates 17 are fixedly connected to both sides of the filter screen 15 , and the fixed plates 17 are movably connected to the outer wall of the frame 1 .

[0035] In specific implementation, by providing a fixing plate 17 , the stability of the filter screen 15 clamped in the frame 1 is improved to prevent the filter screen 15 from sliding out of the water outlet 16 when the water flow is too large.

[0036] For further information, see Figure 4 The top of the limiting column 13 is connected to a limiting plate, and the outer diameter of the limiting plate is larger than the inner diameter of the arc groove 12.

[0037] During specific implementation, in order to ensure the stability of the limiting column 13 sliding in the arc groove 12, a limiting plate is connected to the top of the limiting column 13, and the outer diameter of the limiting plate is set to be larger than the inner diameter of the arc groove 12 to prevent the limiting column 13 from detaching from the transmission gear 10 when sliding in the arc groove 12, thereby affecting the stable operation of the device.

[0038] For further information, see Figure 3 The shape of the arc plate 7 is set to be arc-shaped, and anti-slip lines are set on the arc plate 7. The number of the arc plates 7 is set to four.

[0039] In specific implementation, by setting the curved plate 7 to be curved and adding anti-slip grooves on the inner side, the lens is fit to the curved plate 7, increasing the contact area between the two, and by setting the number of curved plates 7 to four, the stability of the optical lens when being clamped and fixed is improved.

[0040] Working principle: When using the grinding component 2 in the frame 1 to grind the optical lens, first place the optical lens on the suction cup 11, and then start the drive motor 9. The drive motor 9 drives the drive gear 8 coaxially connected thereto to start rotating. When the drive gear 8 rotates counterclockwise, the transmission gear 10 meshing with the drive gear 8 rotates clockwise. When the transmission gear 10 rotates, the limit column 13 slides on it along the arc groove 12 opened on the transmission gear 10, and the moving rod 6 fixedly connected to the limit column 13 moves inward in the groove opened in the rotating bracket 4. The arc plate 7 fixedly connected to the moving rod 6 clamps the optical lens in the process of synchronous movement with the moving rod 6. After clamping is completed, turn off the drive motor 9. At this time, the optical lens is fixed on the suction cup 11, and the grinding component 2 on the top of the mobile frame 1 moves downward until it is in contact with the optical lens. Then start the servo motor 14, and the rotating shaft 5 rotatably connected to the servo motor 14 drives the rotating bracket 4 fixedly connected to the rotating shaft 5 to start rotating. When the rotating bracket 4 rotates, the grinding of the optical lens begins.

[0041] During the polishing process, in order to avoid damaging the lens, pure water is injected into the water washing pipe 3 to wash the lens and flush out the debris generated during the polishing process. The water flows out from the water outlet 16 opened on both sides of the frame 1, and the debris remains on the filter 15 clamped in the water outlet 16. After the polishing and washing process is completed, the screws on the fixing plate 17 can be unscrewed, the filter 15 can be removed and cleaned.
