Description

Technical Field

[0001] This utility model relates to the field of optical glass lens processing technology, and in particular to a polishing device for optical glass. Background Technology

[0002] Optical glass lenses are made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent internal stress from forming in the glass block. After cooling, the glass block must be measured by optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. After the qualified glass block is heated and forged into an optical lens blank, it needs to be polished by an optical glass lens processing polishing device.

[0003] If the glass position shifts or the grinding wheel wears during the polishing process of optical glass polishing equipment, and cannot be compensated for by adaptive pressure adjustment, it can easily lead to processing accidents or batch quality problems. Utility Model Content

The preload of the spring can be adjusted according to the glass material and polishing requirements, so that the grinding contact wheel applies appropriate pressure to the glass surface. This ensures the removal rate while preventing excessive pressure from causing the glass to break. The fixed connection between the limiting post and the rotating connecting plate restricts the rotation angle, preventing excessive oscillation of the mechanism from causing polishing deviation, and further improving the processing accuracy.

[0018] Reference Figure 1-4This utility model discloses a polishing device for optical glass, comprising: a grinding box 1 and auxiliary components. Three drive motors 12 are fixedly connected to the upper surface of the grinding box 1, providing power to the entire polishing device. The rotation of the output ends of the three drive motors 12 drives the movement of subsequent components. Each of the three drive motors 12 has a fixedly connected rotating column 13, which transmits the rotational power of the drive motors 12, providing a foundation for the rotation of subsequent components. A first connecting plate 14 is fixedly connected to the outer surface of the rotating column 13, serving a connecting and fixing function, transmitting the rotation of the rotating column 13 to the upper components. A first fixed mounting column 15 is fixedly connected to the upper surface of the first connecting plate 14, providing rotational support for a second connecting plate 17 and also serving as the mounting location for a spring 16. The second connecting plate 17 is rotatably connected to the upper surface of the first fixed mounting column 15. The second connecting plate 17 rotates on the first fixed mounting column 15 and can cooperate with the spring 16 to adjust the pressure on the upper component. The lower surface of the second connecting plate 17 abuts against the spring 16, which is sleeved on the first fixed mounting column 15. Through the elastic force generated by the elastic deformation, the second connecting plate 17 applies adjustable pressure to the upper component. The upper surface of the second connecting plate 17 is fixedly connected to the second fixed mounting column 18, which provides rotational support for the rotating connecting plate 19, allowing the rotating connecting plate 19 to rotate within a certain range. The outer surface of the second fixed mounting column 18 is rotatably connected to the rotating connecting plate 19. The rotating connecting plate 19 rotates on the second fixed mounting column 18, which can change its relative position and angle with the lower component. The side wall of the rotating connecting plate 19 is fixedly connected to the limit post 8, which is used to limit the rotation range of the rotating connecting plate 19 and ensure the stability and safety of the device operation.

[0019] Spring 16 and the first fixed mounting post 15 are sleeved together, and the two cooperate to provide elastic support and pressure adjustment function for the second connecting plate 17. The second connecting plate 17 is located above the first connecting plate 14. This positional relationship allows spring 16 to effectively exert its elastic force and adjust the pressure between the second connecting plate 17 and the first connecting plate 14. Three drive motors 12 are symmetrically arranged on the upper surface of the grinding box 1. The symmetrical arrangement ensures the balance of power output and makes the device operate more stably. Rotating connecting plates 19 and the first connecting plate 14 are arranged in parallel. The parallel arrangement helps to achieve smooth power transmission and uniform pressure distribution. The number of rotating connecting plates 19 and the number of second connecting plates 17 are correspondingly arranged to ensure the consistency and coordination of the connection relationship between the components. Auxiliary group The components are located on the outer surface of the grinding box 1. The auxiliary components include a controller 2, a grinding groove 3, a grinding contact wheel 4, a mounting base 5, a connecting column 6, a connecting rotating base 7, a positioning column 9, a counterweight 10, and a fixing column 11. These auxiliary components, together with the grinding box 1, constitute a complete polishing system. The controller 2 is fixedly connected to the front surface of the grinding box 1. The controller 2 controls the operation of components such as the drive motor 12, achieving precise control of the polishing process. A grinding groove 3 is provided on the upper surface of the grinding box 1. The grinding groove 3 provides working space for the grinding disc device and the grinding contact wheel 4, serving as the polishing area for optical glass. The grinding disc device is installed inside the grinding groove 3. The grinding disc device cooperates with the grinding contact wheel 4 to grind and polish the optical glass. The lower limit column 8... A connecting rotating seat 7 is fixedly connected to the surface, connecting the limiting post 8 and the fixed post 11, allowing them to rotate relative to each other. The fixed post 11 is rotatably connected to the upper surface of the connecting rotating seat 7, and the fixed post 11 rotates on the connecting rotating seat 7, adjusting its relative position with the limiting post 8. A positioning post 9 is fixedly connected to the upper surface of the fixed post 11, used to fix the counterweight 10, keeping it stable on the fixed post 11. Two counterweights 10 are sleeved on the outer surface of the positioning post 9, and the counterweights 10 apply pressure to the fixed post 11 and the components below it through their own weight, enhancing the contact pressure between the grinding contact wheel 4 and the optical glass. A connecting post 6 is fixedly connected to the lower surface of the fixed post 11, connecting the fixed post 11 and the mounting base 5. The lower surface of the connecting column 6 is fixedly connected to a mounting base 5, which is used to fix the grinding contact wheel 4 so that it can work stably. The grinding contact wheel 4 is the component that directly contacts the optical glass for grinding and polishing. The upper surfaces of the counterweight block 10 and the fixing column 11 abut against each other, and the two cooperate to provide downward pressure to the grinding contact wheel 4 through gravity. The fixing column 11 is located above the limiting column 8. This positional relationship ensures the connection stability and motion coordination between the components. The grinding contact wheel 4 is located inside the grinding groove 3. The grinding contact wheel 4 cooperates with the grinding disc device in the grinding groove 3 to polish the optical glass. The size of the grinding contact wheel 4 is adapted to the size of the grinding groove 3.The appropriate dimensions ensure that the grinding contact wheel 4 can work effectively within the grinding tank 3 without shaking or interference. The connecting post 6 is located between the three second connecting plates 17, receiving pressure and movement transmitted from them. The connecting post 6 extends to the lower surface of the connecting rotating seat 7, achieving a stable connection with components such as the fixed post 11.

[0020] Working principle: First, the optical glass is placed on the grinding disc device in the grinding tank 3. The counterweight 10 is accurately fitted onto the fixed column 11 by the positioning column 9. The weight of the counterweight 10 provides the basic pressure for subsequent grinding. At the same time, it is ensured that the grinding contact wheel 4 is located in the grinding tank 3 and corresponds to the position of the grinding disc device, ensuring that its size is adapted to the grinding tank 3 and avoiding shaking or interference. The controller 2 on the front surface of the grinding box 1 starts three drive motors 12. The output end of the drive motor 12 drives the rotating column 13 to rotate. The rotating column 13 transmits power to the first connecting plate 14, which in turn drives the first fixed mounting column 15 and related components to move. The second connecting plate 17 on the first fixed mounting column 15 can apply adjustable pressure to the upper component under the elastic force of the spring 16. The second connecting plate 17 drives the second fixed mounting column 18 and the rotating connecting plate 11. 9. The rotating connecting plate 19 transmits power sequentially to the mounting base 5 and the grinding contact wheel 4 through the limiting post 8, the connecting rotating seat 7, the fixed post 11, and the connecting post 6. During this process, the rotating connecting plate 19 is set parallel to the first connecting plate 14 to ensure smooth power transmission and uniform pressure distribution. After receiving power and pressure, the grinding contact wheel 4 cooperates with the grinding disc device to grind and polish the optical glass in the grinding groove 3. During the polishing process, the limiting post 8 restricts the rotation range of the rotating connecting plate 19 to ensure stable operation of the device. The connecting post 6 is located between the three second connecting plates 17 and continuously receives and transmits pressure and motion to ensure stable operation of the grinding contact wheel 4. After the polishing of the optical glass is completed, the drive motor 12 is turned off by the controller 2. After the device has completely stopped operating, the polished optical glass is taken out, and the device is cleaned and maintained.
