[0002] A composite lens is an optical lens composed of a variety of lenses of different materials or functions. It is usually made up of multiple layers of lens materials with different refractive indices that are tightly fitted together or combined through a special process. Common composite lenses may include one or more layers of glass lenses, resin lenses, etc. The material and optical properties of each layer of lenses are carefully designed and selected to achieve the best combination effect. In the processing of composite lenses, fixtures are often required for clamping and fixing.
[0003] However, the prior art still has the following problems:
[0004] Most of the lens clamps used for composite lenses in the existing technology are not convenient for adjusting the clamping points. The usual clamping structure design is relatively simple and fixed. It may be barely applicable to standard lenses with regular shapes, but it is difficult to find a suitable support point position when facing composite lenses with irregular shapes or special structures. Since it cannot be flexibly adjusted according to the actual situation of the lens, it is easy to cause uneven force on the lens during the clamping process, and the stability is greatly reduced, which in turn increases the risk of displacement, shaking or even damage of the lens during processing, testing or transportation.
[0005] In view of the above problems, the inventors propose a lens holder for a composite lens to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.
[0019] Embodiment: as Figures 1-4As shown, the utility model provides a lens clamp for compound lenses, including a base plate 1, and mounting plates 3 are symmetrically fixed on both sides of the base plate 1. The mounting plates 3 can be used to stably mount the entire clamp on a corresponding work platform or equipment to ensure that the clamp will not easily move during the lens clamping operation, laying a solid foundation for subsequent precise clamping work. A horizontal plate 12 is fixed on one side of the upper surface of the base plate 1, and a support plate 13 is fixed on the upper end of the horizontal plate 12. A placement arc plate 11 is fixed on the upper surface of the base plate 1, and a clamping arc is slidably provided on the upper surface of the placement arc plate 11. Plate 2, and the arc groove 24 is symmetrically opened on the clamping arc plate 2, a sliding post 25 is slidably provided in the arc groove 24, one end of the sliding post 25 is movably inserted with a sleeve 26, and the sleeve 26 is fixed with a contact plate 28 at one end close to the plate 13, the outer surface of the sliding post 25 is fixedly sleeved with a support plate 29, and a plurality of springs 27 are fixed between the support plate 29 and the corresponding sleeve 26, and there are six springs 27 on one side, and the six springs 27 are distributed in a ring shape, the support plate 29 is movably fitted with the clamping arc plate 2, and the other end of the sliding post 25 is fixed with a fixed plate 210, the outer surface of the fixed plate 210 A fixing plate 211 is fixed on both sides, and the fixing plate 211 is connected to the clamping arc plate 2 by bolts. A plurality of bolt holes 212 are opened on one side of the clamping arc plate 2, and the plurality of bolt holes 212 are distributed in a ring shape. First, the composite lens is placed on the placement arc plate 11. When the clamping arc plate 2 gradually approaches the placement arc plate 11, the contact plate 28 on the clamping arc plate 2 first contacts the lens. As the clamping arc plate 2 moves further, the contact plate 28 is resisted by the lens, prompting the slide column 25 to slide in the sleeve 26, while compressing the spring 27, which is distributed in a ring shape. Multiple springs 27 can evenly disperse the pressure, so that the contact plate 28 can be adaptively adjusted according to the shape and surface condition of the lens, thereby providing a stable and uniform clamping force to avoid damage to the lens. According to the shape, size and specific clamping requirements of the lens, the fixing plate 211 can be connected with the bolt holes 212 in the appropriate position with bolts to determine the fixed position of the sliding column 25, thereby adjusting the clamping point so that the contact plate 28 forms a stable support point at different positions around the lens, ensuring that the lens is reliably fixed between the contact plate 13 and the clamping arc plate 2.
[0020] A clamping block 21 is fixedly provided on the lower surface of the clamping arc plate 2, and a clamping groove 22 is provided on the upper surface of the placed arc plate 11 for use with the clamping block 21. During the movement of the clamping arc plate 2, the clamping block 21 on the lower surface of the clamping arc plate 2 slides along the clamping groove 22 on the upper surface of the placed arc plate 11, guiding and limiting the movement of the clamping arc plate 2, ensuring that it is stably close to the placed arc plate 11.
[0021] like Figures 1-5As shown, a non-slip pad 14 is fixed on the side of the plate 13 close to the clamping arc plate 2. The non-slip pad 14 is made of a special non-slip material with a certain surface roughness and softness, which improves the fixing effect while reducing damage to the lens. A driving plate 4 is fixed on the side of the upper surface of the bottom plate 1 away from the horizontal plate 12. A screw column 41 is threaded through one side of the driving plate 4, and a connecting column 43 is fixed on the inner end of the screw column 41. A support plate 23 is rotatably provided on one end of the connecting column 43, and both ends of the support plate 23 are fixedly connected to the clamping arc plate 2. The screw column 41 is threaded through the one side of the driving plate 4. A knob 42 is fixedly provided at the outer end. After the composite lens is placed on the placement arc plate 11, the knob 42 is turned when it needs to be fixed and clamped. The knob 42 drives the screw post 41 to rotate. Since the screw post 41 is connected to the driving plate 4 by a thread, when the screw post 41 rotates, the connecting post 43 at the inner end thereof pushes the supporting plate 23 rotatably connected thereto, driving the clamping arc plate 2 to move toward the abutment plate 13. The knob 42 is turned to drive the screw post 41 to control the movement of the clamping arc plate 2. The operation is simple and convenient, easy to master, and allows the operator to quickly and accurately complete the lens clamping operation, thereby improving work efficiency.
[0022] Two limiting columns 44 are fixedly provided on one side of the support plate 23 close to the driving plate 4, and one end of the limiting column 44 passes through the driving plate 4 and is fixed with a limiting plate 45. The limiting column 44 and the limiting plate 45 limit the moving position of the support plate 23, further enhancing the stability and safety of the clamp and ensuring the reliability and repeatability of the clamping action.
[0023] Working principle: First, place the composite lens on the placement arc plate 11. When the clamping arc plate 2 gradually approaches the placement arc plate 11, the contact plate 28 on the clamping arc plate 2 first contacts the lens. As the clamping arc plate 2 moves further, the contact plate 28 is subjected to the resistance of the lens, prompting the slide post 25 to slide in the sleeve 26 and compressing the spring 27 at the same time. The multiple springs 27 distributed in an annular shape can evenly disperse the pressure, so that the contact plate 28 can be adaptively adjusted according to the shape and surface condition of the lens, thereby providing a stable and uniform clamping force to avoid damage to the lens. According to the shape, size and specific clamping requirements of the lens, the fixing plate 211 can be connected with the bolt hole 212 at the appropriate position with bolts to determine the fixed position of the slide post 25, thereby adjusting the clamping point so that the contact plate 28 forms a stable support point at different positions around the lens, ensuring that the lens is reliably fixed between the contact plate 13 and the clamping arc plate 2.
[0024] The clamping block 21 on the lower surface of the clamping arc plate 2 slides along the clamping groove 22 on the upper surface of the placement arc plate 11, guiding and limiting the movement of the clamping arc plate 2, ensuring that it is stably close to the placement arc plate 11;
[0025] After the composite lens is placed on the placing arc plate 11, when it needs to be fixed and clamped, the knob 42 is rotated, the knob 42 drives the wire column 41 to rotate, because the wire column 41 and the driving plate 4 are threadedly connected, when the wire column 41 rotates, the connecting column 43 at the inner end of the wire column 41 pushes the support plate 23 which is rotationally connected with the connecting column 43, drives the clamping arc plate 2 to move towards the abutting disc 13, the rotation of the knob 42 drives the wire column 41 to control the movement of the clamping arc plate 2, the operation is simple and convenient, easy to master, can make the operator quickly and accurately complete the clamping operation of the lens, improves the work efficiency;
[0026] The limiting column 44 and the limiting disc 45 limit the moving position of the support plate 23, further enhance the stability and safety of the clamp, ensure the reliability and repeatability of the clamping action.
[0027] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technologies, the present application also intends to include these modifications and variations.
