[0016] 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.

[0017] Example: Figure 1-3 As shown, this utility model provides a lens edging machine, including a base plate 1, which serves as the supporting foundation for the entire equipment. A positioning mechanism 2 and a grinding mechanism 3 are fixedly provided on its upper surface to achieve precise positioning and efficient grinding of the lens.

[0018] The positioning mechanism 2 includes a positioning frame 28, which is located above the base plate 1 and provides a stable platform for clamping and positioning the lens. A servo cylinder 20 is fixedly mounted on the upper surface of the base plate 1. The servo cylinder 20 serves as a power source, and its output end is fixedly connected to one side of the positioning frame 28. Through telescopic movement, it drives the positioning frame 28 to move up and down. A servo motor 22 is mounted on one side of the positioning frame 28, providing precise power output. A bidirectional threaded rod 26 is fixedly mounted on its output end, enabling bidirectional transmission through rotation. Two clamping frames 25 are threaded onto the outer surface of the bidirectional threaded rod 26. The two clamping frames 25 move in opposite directions as the bidirectional threaded rod 26 rotates, thereby clamping the lens. Each of the two clamping frames 25 has a clamping head 29 rotatably mounted on one side. The clamping head 29 is made of flexible material to ensure that the lens is clamped securely without damaging the lens surface. One end of one clamping head 29 is also fixed with a rocker wheel 201. The angle of the clamping head 29 can be adjusted by manually operating the rocker wheel 201 to facilitate polishing the outer side of the lens.

[0019] A positioning support frame 21 is fixedly provided on the side of the positioning frame 28 near the servo motor 22. One side of the positioning support frame 21 is fixedly engaged with one end of the servo motor 22 to provide solid support for the servo motor 22. Multiple sets of sliders 24 are fixedly provided on the lower surface of the positioning frame 28, and multiple sets of slide rails 23 that match the sliders 24 are fixedly provided on the upper surface of the base plate 1. The sliders 24 and slide rails 23 slide in cooperation to ensure the stability and accuracy of the positioning mechanism 2 during movement. An anti-blocking opening 27 is also provided on one side of the positioning frame 28 to cooperate with the grinding mechanism 3 to avoid interference between the positioning mechanism 2 and the grinding mechanism 3 during the grinding process.

[0020] The polishing mechanism 3 includes a housing 33, the lower surface of which is fixedly connected to the upper surface of the base plate 1 to protect the internal transmission components. A transmission motor 30 is provided on one side of the housing 33, which provides power output. A drive gear 37 is fixedly provided at its output end, and power is transmitted through gear transmission. A driven gear 32 is meshed on the outer surface of the drive gear 37. The driven gear 32 rotates as the drive gear 37 rotates. A polishing wheel 35 is fixedly provided at the end of the driven gear 32 away from the transmission motor 30. The polishing wheel 35 is the main component for polishing operations. A polishing ring 36 is fixedly provided on its outer surface for fine polishing of the lens edge.

[0021] To ensure the stable operation of the transmission components, a transmission base 31 is fixedly installed on the upper surface of the base plate 1. The transmission base 31 is fixedly engaged with the transmission motor 30, providing solid support for the transmission motor 30. At the same time, to prevent debris and dust generated during the grinding process from damaging the equipment, two dust cover rings 34 are snapped onto both sides of the outer shell 33 to effectively block external impurities from entering the equipment. In addition, to improve the stability and durability of the gear transmission, rotating bearings 38 are provided at both ends of the drive gear 37 and the driven gear 32 to ensure the smoothness and accuracy of the gears during rotation.

[0022] Working principle: In the lens edging machine, the operator first holds the lens to be processed in an appropriate position between two clamping heads 29 through the positioning mechanism 2. Then, the servo motor 22 starts working, and its output end drives the bidirectional threaded rod 26 to rotate. Since the outer surface of the bidirectional threaded rod 26 is threaded with two clamping frames 25, the two clamping frames 25 will move synchronously or in opposite directions with the rotation of the threaded rod, thereby achieving a stable clamping of the lens. Subsequently, the servo cylinder 20 is started, and its output end pushes the positioning frame 28 to slide smoothly along the slide rail 23 on the upper surface of the base plate 1, so that it can drive the lens to cooperate with the grinding mechanism 3 for grinding. During the clamping process, the operator can adjust the angle of the lens through the rocker wheel 201 to facilitate grinding the outer side of the lens. The positioning support frame 21 provides solid support for the servo motor 22 to ensure its stability during operation. The entire positioning process is fast and accurate, laying a solid foundation for subsequent grinding operations.

[0023] After the lens is securely clamped by the positioning mechanism 2, the polishing mechanism 3 begins to operate. First, the drive motor 30 starts, and its output drives the drive gear 37 to rotate. Since the outer surface of the drive gear 37 meshes with the driven gear 32, the driven gear 32 rotates synchronously with the drive gear 37. A polishing wheel 35 is fixedly mounted on the end of the driven gear 32 away from the drive motor 30, so the polishing wheel 35 also rotates with the driven gear 32. A polishing ring 36 is fixedly mounted on the outer surface of the polishing wheel 35. The polishing ring 36 contacts the edge of the lens and performs fine polishing on the edge of the lens through friction. During the polishing process, the dust cover ring 34 effectively blocks the debris and dust generated during polishing, preventing them from entering the equipment and damaging the transmission components. At the same time, the rotating bearing 38 provides stable rotational support for the drive gear 37 and the driven gear 32, ensuring the smooth progress of the polishing operation. The entire polishing process is efficient and precise, which can significantly improve the quality and efficiency of lens processing.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
