Description

Technical Field

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

[0002] As a core component of precision optical instruments, the surface quality and precision of optical lenses directly affect key indicators such as imaging performance and light transmission. Therefore, extremely high requirements are placed on the grinding and processing of optical lenses. Grinding equipment for optical lenses is crucial for achieving high-precision lens manufacturing. Through grinding and polishing processes, defects and scratches are removed from the lens surface, enabling the lens to achieve the required flatness, smoothness, and curvature parameters. It is widely used in numerous fields such as camera lenses, microscopes, telescopes, and laser equipment. With the continuous development of optical technology, the demands for precision and production efficiency of optical lenses are increasing, making the development of efficient and precise grinding equipment an important issue in the industry.

[0003] In existing technologies, optical lens polishing devices typically employ a combination of mechanical transmission and manual assistance. Their mechanical structure generally includes a fixed worktable, a support platform for holding the lens, and a polishing mechanism driven by a motor. Technically, the polishing head is rotated via belt drive or gear transmission, and the polishing head, propelled by a cylinder or hydraulic cylinder, approaches the lens surface to perform the polishing operation. For lens clamping, manually adjustable clamps, such as three-jaw chucks or manual screw clamps, are commonly used. Operators need to manually adjust the position and tightness of the clamps according to the lens size to secure the lens.

[0004] However, existing technologies require manual and repeated adjustments of the fixture to accommodate lenses of different specifications. This is not only cumbersome, but also makes it difficult to ensure a tight fit between the fixture and the lens. The lens is prone to shaking during the grinding process due to unstable clamping, which affects the grinding accuracy of the lens and makes it difficult to meet the processing requirements of high-precision optical lenses. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a grinding device for optical lenses, which aims to improve the existing technology that requires repeated manual adjustment of the clamp to adapt to different specifications of lenses. This is not only cumbersome to operate, but also makes it difficult to ensure the tight fit between the clamp and the lens, and the lens is prone to shaking due to unstable clamping during the grinding process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for optical lenses, comprising a worktable, a motor fixedly connected inside the worktable, a worm gear fixedly connected to the output end of the motor, a worm wheel rotatably connected inside the worktable, the worm gear meshing with the worm wheel, a rotating disk fixedly connected to the upper surface of the worm wheel, connecting rods rotatably connected to both ends of the rotating disk, a sliding plate rotatably connected to one end of the connecting rod, a slider fixedly connected to the upper surface of the sliding plate, a V-shaped clamp rotatably connected to the inner wall of the slider, a roller rotatably connected to the outer wall of the V-shaped clamp, and a reset component provided on the inner wall of the V-shaped clamp;

[0007] The reset assembly includes a rotating shaft, the outer wall of which is rotatably connected to the inside of the slider, both ends of which are fixedly connected to the inside of the slider, and a torsion spring is sleeved on the outer wall of the rotating shaft.

[0008] Furthermore, a support frame is fixedly connected to the outer wall of the workbench, a cylinder is fixedly connected to the top of the support frame, a movable seat is fixedly connected to the output end of the cylinder, a second motor is fixedly connected inside the movable seat, a mounting base is fixedly connected to the output end of the second motor, and a grinding component is provided on the outer wall of the mounting base.

[0009] Furthermore, the grinding assembly includes a grinding plate disposed below the mounting base, a connecting plate slidably connected to the outer wall of the mounting base, and a fixing bolt disposed inside the connecting plate.

[0010] Furthermore, one side of the outer wall of the fixing bolt is threaded into the interior of the mounting base, and the upper surface of the grinding plate is fixedly connected to the lower surface of the connecting plate.

[0011] Furthermore, a limiting rod is fixedly connected to the upper surface of the movable seat, and the outer wall of the limiting rod is slidably connected to the inside of the support frame.

[0012] Furthermore, a platform is fixedly connected to the upper surface of the workbench, and the platform is positioned directly below the grinding plate.

[0013] Furthermore, the outer wall of the rotating disk is rotatably connected to the inside of the worktable, and the outer wall of the sliding plate is slidably connected to the inside of the worktable.

[0014] Furthermore, one end of the torsion spring is fixedly connected to the inside of the V-shaped clamp, and the other end of the torsion spring is fixedly connected to the inner wall of the slider.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the precise meshing of the worm gear and worm wheel drives the rotating disk, connecting rod, slide plate, and slider in tandem, enabling the V-shaped clamp to automatically move towards the lens. The V-shaped clamp can rotate freely around its axis, ensuring a tight fit between both ends and the lens, achieving stable clamping and effectively preventing lens wobbling during grinding from affecting processing accuracy. Simultaneously, the torsion spring allows the V-shaped clamp to automatically reset after release, improving the convenience and reliability of clamping and positioning, making it suitable for clamping lens sizes.

[0017] 2. In this invention, the drive cylinder propels the moving seat to move precisely, and the guiding action of the limit rod ensures that the grinding plate accurately reaches the lens surface.

Furthermore, the grinding plate is connected to the mounting base and connecting plate via fixing bolts. When the grinding plate wears down due to prolonged use, it can be quickly disassembled and replaced, reducing equipment downtime for maintenance, lowering operational difficulty, and further ensuring the continuity and efficiency of lens grinding, thus improving overall production efficiency.

Detailed Implementation

[0025] 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.

[0026] Reference Figure 1 - Figure 5 An embodiment of this utility model provides a grinding device for optical lenses, including a worktable 1, a motor 2 fixedly connected inside the worktable 1, a worm gear 3 fixedly connected to the output end of the motor 2, a worm wheel 4 rotatably connected inside the worktable 1, the worm gear 3 meshing with the worm wheel 4, a rotating disk 5 fixedly connected to the upper surface of the worm wheel 4, connecting rods 6 rotatably connected to both ends of the rotating disk 5, a sliding plate 7 rotatably connected to one end of the connecting rods 6, a slider 8 fixedly connected to the upper surface of the sliding plate 7, a V-shaped clamp 9 rotatably connected to the inner wall of the slider 8, a roller 10 rotatably connected to the outer wall of the V-shaped clamp 9, and a reset component provided on the inner wall of the V-shaped clamp 9;

[0027] The reset assembly includes a rotating shaft 11, the outer wall of which is rotatably connected to the inside of the slider 8, both ends of which are fixedly connected to the inside of the slider 8, a torsion spring 12 sleeved on the outer wall of the rotating shaft 11, the outer wall of the rotating disk 5 being rotatably connected to the inside of the worktable 1, the outer wall of the slide plate 7 being slidably connected to the inside of the worktable 1, one end of the torsion spring 12 being fixedly connected to the inside of the V-shaped clamp 9, and the other end of the torsion spring 12 being fixedly connected to the inner wall of the slider 8.

[0028] Specifically, the lens to be processed is first placed on the platform 22. The motor 2 is started, driving the worm gear 3 to rotate. Because the worm gear 3 and the worm wheel 4 are precisely meshed, the worm wheel 4 rotates accordingly, driving the connected rotating disk 5 to rotate synchronously. When the rotating disk 5 rotates, the connecting rods 6 at both ends move along a predetermined trajectory, causing the slide plate 7 to slide inside the worktable 1. This, in turn, drives the slider 8 fixed on the slide plate 7 to move relative to the lens, gradually approaching it and causing the V-shaped clamp 9 to move closer to the lens. When one end of the V-shaped clamp 9 is supported by the lens, it will rotate freely around the rotating shaft 11, so that the other end also fits against the lens, ensuring close contact at both ends. This not only stably clamps the lens, but also causes the torsion spring 12 to deform through the rotation of the V-shaped clamp 9. When released, the torsion spring 12 rotates back, allowing it to automatically reset, achieving stable positioning.

[0029] Reference Figure 1 - Figure 5A support frame 13 is fixedly connected to the outer wall of the workbench 1. A cylinder 14 is fixedly connected to the top of the support frame 13. A movable seat 20 is fixedly connected to the output end of the cylinder 14. A motor 21 is fixedly connected inside the movable seat 20. A mounting seat 15 is fixedly connected to the output end of the motor 21. A grinding assembly is provided on the outer wall of the mounting seat 15. The grinding assembly includes a grinding plate 19. The grinding plate 19 is located below the mounting seat 15. A connecting plate 16 is slidably connected to the outer wall of the mounting seat 15. A fixing bolt 17 is provided inside the connecting plate 16. One side of the outer wall of the fixing bolt 17 is threaded into the inside of the mounting seat 15. The upper surface of the grinding plate 19 is fixedly connected to the lower surface of the connecting plate 16. A limit rod 18 is fixedly connected to the upper surface of the movable seat 20. The outer wall of the limit rod 18 is slidably connected to the inside of the support frame 13. A shelf 22 is fixedly connected to the upper surface of the workbench 1. The shelf 22 is located directly below the grinding plate 19.

[0030] Specifically, the drive cylinder 14 pushes the movable seat 20 to slide smoothly onto the lens surface, and the limit rod 18 ensures that it moves accurately along a predetermined path. After the movable seat 20 reaches the designated position, the motor 21 starts, driving the grinding plate 19 to rotate. The high-speed rotating grinding plate 19 performs uniform and effective grinding on the lens surface, improving the surface quality and fineness of the product. Because prolonged use will cause wear on the grinding plate 19, affecting the grinding effect, the connecting plate 16 and the grinding plate 19 can be easily disassembled by rotating the drive fixing bolt 17 inside the mounting base 15 and the connecting plate 16. This makes the replacement process simple and quick, greatly improving work efficiency and achieving efficient lens grinding.

[0031] Working principle: When using this polishing device, first, accurately place the lens to be processed above the table 22. Then, start the motor 2, which drives the worm gear 3 to rotate stably. Due to the precise meshing relationship between the worm gear 3 and the worm wheel 4, the worm wheel 4 will rotate accordingly, driving the connected rotating disk 5 to rotate synchronously. As the rotating disk 5 rotates, the connecting rods 6 at both ends will move according to a predetermined trajectory. When the connecting rods 6 move, the slide plate 7 will slide inside the worktable 1, driving the slider 8 fixed on the slide plate 7 to move relative to it. This allows for a gradual approach to the lens, causing the V-clamp 9 to move closer to the lens. When one end of the V-clamp 9 is supported by the lens, it will rotate freely on the outer wall of the rotating shaft 11, allowing the other end of the V-clamp 9 to also fit against the lens. This ensures that both ends of the V-clamp 9 are tightly fitted against the lens, not only ensuring that the lens is stably clamped, but also causing the torsion spring 12 to deform through the rotation of the V-clamp 9. When the V-clamp 9 is released, the torsion spring 12 can automatically return to its initial state through its rotation, achieving stable positioning.

[0032] In addition, the drive cylinder 14 pushes the moving seat 20 to move smoothly onto the surface of the lens. The limit rod 18 ensures that the moving seat 20 moves precisely along the predetermined path. Once the moving seat 20 reaches the designated position, the motor 21 starts and drives the grinding plate 19 to start rotating. The high-speed rotation of the grinding plate 19 makes the surface of the lens uniform and effective, thereby improving the surface quality and fineness of the product. It is worth noting that the grinding plate 19 will wear down due to long-term use, affecting the grinding effect. By driving the fixing bolt 17 to rotate inside the mounting base 15 and the connecting plate 16, the connecting plate 16 and the grinding plate 19 can be easily disassembled, making the replacement of the grinding plate 19 extremely simple and quick, greatly improving work efficiency and achieving efficient grinding of the lens.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
