[0001] This utility model relates to the field of optical lens processing technology, specifically a grinding machine used in optical lens processing. Background Technology
[0002] Optical lenses are crucial optical components in the field of optics, capable of refracting, focusing, or diverging light. Different types of optical lenses have different functions and applications.
[0003] In the process of optical lens manufacturing, grinding machines are usually used to process the optical lenses to remove burrs from the surface of the optical lens workpiece, which significantly improves the accuracy and smoothness of the optical lens workpiece surface.
[0004] Currently, in the process of processing optical lenses using grinding machines, the optical lens is usually fixed in place. After processing one side of the optical lens, it needs to be disassembled, flipped, and then refixed before the other side can be processed. This operation is very cumbersome and affects the working efficiency of the grinding machine. Therefore, we have proposed a grinding machine for processing optical lenses to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-6 This utility model provides a technical solution: a grinding machine for optical lens processing, including a machine body 1, a servo electric cylinder 2 installed on the upper part of the machine body 1, a motor 3 fixed on the telescopic end of the servo electric cylinder 2, and a grinding disc 4 installed on the rotation output end of the motor 3.
[0026] Furthermore, the motor 3 and the grinding disc 4 form an up-and-down moving structure on the upper part of the machine body 1 through the servo electric cylinder 2, which facilitates the separation of the grinding disc 4 from the optical lens workpiece 7 and avoids affecting the face-changing operation of the optical lens workpiece 7.
[0027] Furthermore, a water pump 5 is installed on the outside of the machine body 1. The water inlet of the water pump 5 is connected to the bottom of the machine body 1, and the bottom surface of the machine body 1 is inclined to facilitate the collection of grinding fluid. A water spray pipe 6 is installed at the water outlet of the water pump 5. The water spray pipe 6 is located inside the machine body 1 to ensure the normal operation of the grinding process of the optical lens workpiece 7. At the same time, the water inlet of the water pump 5 is equipped with a filter structure to filter out debris and impurities in the grinding fluid and realize the recycling of the grinding fluid.
[0028] An inner bracket 11 is fixed inside the machine body 1. Two screws 12 are installed on the inner bracket 11 through bearings in both directions. The outer ends of the screws 12 are connected to a second motor 13. The second motor 13 is installed on the outside of the inner bracket 11. A rotating clamp 8 and a fixed clamp 9 are respectively threaded onto the two screws 12. The upper ends of the rotating clamp 8 and the fixed clamp 9 hold and connect an optical lens workpiece 7. The optical lens workpiece 7 is located directly below the grinding disc 4.
[0029] Furthermore, both the rotating clamp 8 and the fixed clamp 9 are equipped with chucks at their upper ends, and the chucks are U-shaped. The chuck structure can automatically adjust the clamping position of the optical lens workpiece 7, ensuring that the rotating clamp 8 and the fixed clamp 9 can stably clamp the optical lens workpiece 7.
[0030] Furthermore, the chuck on the rotating fixture 8 is a rotating structure, which enables the optical lens workpiece 7 to rotate normally while being held by the rotating fixture 8. The chuck on the fixed fixture 9 is a fixed structure, which stabilizes the processing state of the optical lens workpiece 7 and ensures the normal grinding operation of the optical lens workpiece 7.
[0031] Furthermore, both the rotating clamp 8 and the fixed clamp 9 form a moving structure on the machine body 1 by rotating the screw 12, and two of each are provided. The threads on the screw 12 are in opposite directions, so that the two rotating clamps 8 and the two fixed clamps 9 move in opposite directions on the screw 12, thereby clamping optical lens workpieces 7 of different sizes and improving the applicability of the grinding machine.
[0032] The optical lens workpiece 7 is connected to the servo electric cylinder 10 on its lower side. The servo electric cylinder 10 is fixedly installed in the middle position inside the inner bracket 11.
[0033] Furthermore, multiple sets of servo electric cylinders 10 are symmetrically arranged in the inner support 11. The symmetry center of the multiple sets of servo electric cylinders 10, the opposing movement center of the rotating fixture 8 and the fixed fixture 9, as well as the center of the optical lens workpiece 7 and the grinding disc 4 are all located on the same vertical line. This can ensure the stability of the optical lens workpiece 7 and also ensure that the grinding of the optical lens workpiece 7 is stable and normal.
[0034] Furthermore, the telescopic end of the servo electric cylinder 210 has a hemispherical structure to ensure normal contact and connection with the optical lens workpiece 7, thereby achieving a support effect.
[0035] Specifically, when using this grinding machine for optical lens processing, the optical lens workpiece 7 is first placed on the servo cylinder 2 10 inside the machine body 1. The servo cylinder 2 10 provides pre-support for the optical lens workpiece 7. Then, the servo cylinder 2 10 is controlled to move up and down to adjust the position of the optical lens workpiece 7 so that the optical lens workpiece 7 is aligned with the chuck at the upper end of the rotating fixture 8 and the fixed fixture 9.
[0036] Then, start motor 13 to drive screw 12 to rotate, so that rotating clamp 8 and fixed clamp 9 can move on the inner support 11, so that rotating clamp 8 and fixed clamp 9 can clamp optical lens workpiece 7 and fix the position of optical lens workpiece 7.
[0037] After the optical lens workpiece 7 is clamped and fixed, the position of the motor 3 and the grinding disc 4 is lowered by the extension of the servo electric cylinder 2. Finally, the grinding disc 4 contacts the upper side of the optical lens workpiece 7, while the lower side of the optical lens workpiece 7 is supported by the servo electric cylinder 10. The grinding disc 4 is rotated by the motor 3 to perform grinding work on the upper side of the optical lens workpiece 7. At the same time, the water pump 5 sprays the grinding fluid at the bottom of the machine body 1 through the water spray pipe 6 between the grinding disc 4 and the optical lens workpiece 7 to cooperate with the grinding work.
[0038] After the grinding work on the upper side of the optical lens workpiece 7 is completed, the grinding disc 4 moves up and separates from the upper surface of the optical lens workpiece 7. The servo cylinder 10 shortens and separates from the lower side of the optical lens workpiece 7. Then, the fixed clamp 9 is controlled to separate outward. The optical lens workpiece 7 can be directly rotated while being held by the rotating clamp 8 to complete the face change of the optical lens workpiece 7. Afterward, the optical lens workpiece 7 is fixed again by the fixed clamp 9. The extended servo cylinder 10 supports the optical lens workpiece 7. Then, the grinding disc 4 moves down to perform the grinding work on the other side of the optical lens workpiece 7.
[0039] The above completes the working process of the grinding machine. Any content not described in detail in this specification is existing technology known to those skilled in the art.
[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
