Description

Technical Field

[0001] This utility model relates to the field of optical processing and fixing technology, specifically to a quick fixing device for circular lenses. Background Technology

[0002] An optical lens is a transparent element made of optical materials (such as glass or plastic) with at least one curved surface (or two curved surfaces). Its basic working principle is to use refraction to change the direction of light propagation, thereby achieving multiple functions such as focusing, diverging, collimation, and imaging.

[0003] In the field of optics, optical lenses are mainly classified into spherical, aspherical, and planar lenses. With the continuous development of society and the optical industry, lenses are widely used in light collection, projection, lighting, detection, and focusing, and are indispensable, especially in the military, civilian, and aerospace fields. In the future, there will be a greater demand for aspherical lenses.

[0004] The requirements for optical lenses vary greatly depending on the application field, which necessitates the processing of optical lenses. However, the shape, size, and diameter of optical lenses used in different fields differ, with circular optical lenses being the most commonly used. During processing, optical lenses need to be fixed. Currently, many fixing devices use mechanical grippers to fix the edges of the lens, which is not only slow but also prone to scratching the lens. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0032] Please see Figures 1-11 This utility model provides a technical solution for a quick fixing device for circular lenses, including a lens fixing device 1, an outer ring bracket 2, an inner ring adjusting bracket 3, a locking mechanism 4, and a clamping mechanism 5. The lens fixing device 1 is provided with an outer ring bracket 2 and an inner ring adjusting bracket 3.

[0033] The outer ring bracket 2 is circular, and the inner wall of the outer ring bracket 2 is provided with fixed sliders 7 at equal angles. The surface of the fixed slider 7 is arc-shaped. The center of the fixed slider 7 is provided with a sliding groove for mounting the slider. Both ends of the sliding groove are provided with anti-detachment blocks. The outer wall of the outer ring bracket 2 is symmetrically provided with locking mechanisms 4. The locking mechanism 4 is provided with a limiting groove 18, which is located inside the outer ring bracket 2.

[0034] The locking mechanism 4 is equipped with an adjusting arm 15 and a fixing ear 17. Both the adjusting arm 15 and the fixing ear 17 have screw holes inside. A screw 16 is set in the screw holes inside the adjusting arm 15 and the fixing ear 17. The adjusting arm 15 and the fixing ear 17 are fitted with the screw 16. The adjusting arm 15 is fitted inside the limiting slide groove 18. The adjusting arm 15 and the inner annular adjusting bracket 3 are integral structures. The fixing ear 17 and the outer annular bracket 2 are integral structures. Limiting heads 19 are symmetrically provided on both sides of the adjusting arm 15. The limiting heads 19 are fitted inside the limiting slide groove 18. The limiting heads 19 and the limiting slide groove 18 cooperate with each other to improve the stability of the relative adjustment process between the outer annular bracket 2 and the inner annular adjusting bracket 3 on the lens fixing device 1.

[0035] The locking mechanism 4 locks and fixes the adjusted outer ring bracket 2 and inner ring adjustment bracket 3 to ensure the clamping and fixing of the inner circular lens, and to ensure that the entire lens is firmly locked and fixed by the lens fixing device 1 during the processing.

[0036] A clamping mechanism 5 is provided between the outer annular bracket 2 and the inner annular adjusting bracket 3. The clamping mechanism 5 is provided with a clamping piece 6. The clamping piece 6 includes a clamping piece base plate 13 and an anti-slip rubber layer 14. The inner surface of the anti-slip rubber layer 14 is uniformly provided with anti-slip ribs, which improves the friction between the clamping piece 6 and the outer wall of the lens being processed, thereby improving the fixing effect after clamping the lens. A telescopic push rod 11 is provided in the center of the outer wall of the clamping piece base plate 13. The telescopic push rod 11 is perpendicular to the outer wall of the clamping piece base plate 13.

[0037] The telescopic push rod 11 has a side limiting groove 10 in the center of both side walls. One end of the telescopic push rod 11 has an adjusting slider 8.

[0039] When fixing the lens to be processed, the lens fixing device 1 first selects the lens to be processed and places it inside the inner annular adjustment bracket 3. The adjusting screw 16 causes relative movement between the outer annular bracket 2 and the inner annular adjustment bracket 3, indirectly driving relative displacement between the adjusting slider 8 and the fixed slider 7. The clamping mechanism 5 moves inward under the drive of the fixed slider 7. The clamping plate base 13 on the clamping mechanism 5 approaches the outer wall of the lens until it is tightly attached. The adjusting outer annular bracket 2 and the inner annular adjustment bracket 3 are locked by the screw 16, thus completing the fixing of the lens to be processed.

[0040] The lens fixing device 1 has a simple structure and is suitable for fixing lenses of different diameters. It can quickly fix the lens, has good stability in fixing the lens, and the side clamping fixation will not hinder the processing of the lens surface.
