[0023] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a precision grinding machine for optical glass processing, including a glass precision grinding frame 1 and a glass clamping and fixing device. A sliding table 2 is slidably installed on the top of the glass precision grinding frame 1, and a precision grinding machine 3 is installed inside the sliding table 2. A chute 4 is opened on the top of the glass precision grinding frame 1. The glass clamping and fixing device includes a guide rod 6, two sliders 5, two fixed clamping plates 7, a pressing plate 12, a fixed block 14, a threaded rod 15 and a turntable 16. The guide rod 6 is fixedly connected inside the chute 4, and both sliders 5 are slidably connected inside the chute 4. Both sliders 5 are slidably sleeved on the surface of the guide rod 6. The two fixed clamping plates 7 are respectively fixedly connected to the tops of the two sliders 5. Triangular clamping grooves 8 and square clamping grooves 9 are opened on the surfaces of the two fixed clamping plates 7. Two inclined grooves 13 are opened on the surface of the pressing plate 12. The pressing plate 12 is slidably connected to the surfaces of the two sliders 5 through the two inclined grooves 13. The fixed block 14 is fixedly connected to the top wall of the glass precision grinding frame 1. The threaded rod 15 is threadedly sleeved inside the fixed block 14. The front end of the threaded rod 15 is rotatably connected to the rear side of the pressing plate 12. The turntable 16 is fixedly connected to the rear end of the threaded rod 15.

[0025] When it is necessary to grind a circular optical lens, the staff can place the circular lens inside the two triangular clamping grooves 8. Then, the staff rotates the threaded rod 15 through the turntable 16. The threaded rod 15 rotates and drives the pressing plate 12 to slide backward through the threaded connection with the fixed block 14. The pressing plate 12 slides backward and drives the two inclined grooves 13 to slide backward and squeeze the surfaces of the two sliders 5. At this time, the two sliders 5 can slide relatively under the extrusion of the pressing plate 12. The two sliders 5 slide relatively and drive the two fixed clamping plates 7 to slide relatively. The two fixed clamping plates 7 can clamp and fix the circular lens on its surface through the two triangular clamping grooves 8 opened on the surface. Similarly, after the staff places the square lens inside the two square clamping grooves 9, the square lens can be clamped and fixed through the two square clamping grooves 9. At the same time, a lifting device is provided on the top of the precision grinding machine 3. The lifting device drives the precision grinding machine 3 to move up and down, and then the two different structured lenses can be ground and processed. The circular structured lens can be clamped and fixed through the two fixed clamping plates 7, and the square optical lens can also be clamped and fixed. When it is necessary to grind the square optical lens, there is no need to replace the precision grinding machine, thereby improving the convenience of the staff for grinding optical lenses with different structural shapes.

[0026] Four convex blocks 10 are fixedly connected to the top of the glass precision grinding frame 1. Guide shafts 11 are fixedly connected inside the two left convex blocks 10 and the two right convex blocks 10. The two guide shafts 11 are slidably sleeved inside the pressing plate 12.

[0027] During the process that the threaded rod 15 rotates to drive the pressing plate 12 to slide back and forth, the pressing plate 12 slides back and forth on the surfaces of the two guide shafts 11. The two guide shafts 11 are used to guide and position the pressing plate 12, ensuring that the pressing plate 12 slides horizontally back and forth and preventing the pressing plate 12 from rotating simultaneously with the threaded rod 15. Furthermore, the pressing plate 12 stably slides back and forth to squeeze the two sliders 5.

[0028] Working principle: For the precision grinding machine for optical glass processing, the operator places the circular lens inside the two triangular card slots 8. Then, the operator rotates the threaded rod 15 through the turntable 16. The threaded rod 15 rotates and drives the pressing plate 12 to slide backward through the threaded connection with the fixed block 14. The pressing plate 12 slides backward and drives the two inclined slots 13 to slide backward to squeeze the surfaces of the two sliders 5. At this time, the two sliders 5 can slide relatively under the squeezing action of the pressing plate 12. The two sliders 5 drive the two fixed clamping plates 7 to slide relatively and clamp the circular lens on its surface through the two triangular card slots 8 opened on the surface for clamping and fixing. Similarly, after the operator places the square lens inside the two square card slots 9, the square lens can be clamped and fixed through the two square card slots 9. The lifting device drives the precision grinding machine 3 to move up and down to grind and process the two lenses with different structures. During the process that the threaded rod 15 rotates to drive the pressing plate 12 to slide back and forth, the pressing plate 12 slides back and forth on the surfaces of the two guide shafts 11, preventing the pressing plate 12 from rotating simultaneously with the threaded rod 15. Furthermore, the pressing plate 12 stably slides back and forth to squeeze the two sliders 5.

[0029] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
