Description

Technical Field

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

[0002] The core components of optical instruments (such as microscopes, telescopes, and camera lenses) typically include precision optical lenses. During the manufacturing process, especially in critical steps like edge grinding, polishing, coating, or inspection, these lenses require secure, precise, and damage-free fixing. Traditional fixing methods or simple clamps are insufficient to meet the stringent requirements of high-precision optical processing for lens positioning stability, uniform force distribution, and ease of operation. Therefore, developing a dedicated fixing device for optical lens processing is crucial for improving processing accuracy, ensuring finished lens quality, and increasing production efficiency.

[0003] However, existing devices or methods for fixing optical lenses often have the following shortcomings: On the one hand, the clamping mechanism is often simply designed, and the clamping force is not easy to control precisely and is unevenly distributed, which can easily lead to micro-displacement, deflection, or even breakage of the lens due to excessive local stress during processing, seriously affecting processing accuracy and lens yield; on the other hand, there is a lack of a flexible adjustment mechanism that can effectively adapt to lenses of different sizes or shapes, as well as stability to resist vibrations generated during the operation of processing equipment (such as grinding machines), making it difficult for the lens to maintain an ideal fixed posture under high-speed rotation or high-frequency vibration. Utility Model Content

[0004] This invention provides a dedicated fixing device that can provide stable, reliable, adjustable and non-destructive clamping, thereby further improving the processing technology of optical instruments.

[0005] The technical solution adopted by this utility model is as follows: a fixing device for optical instrument processing, including a base plate, a lens mounting seat fixedly connected to the base plate, side plates fixedly connected to both sides of the lens mounting seat on the base plate, a straight groove provided on the lens mounting seat and a fixing block fixedly connected to the lens mounting seat in the straight groove, two clamping seats slidably connected to the lens mounting seat at the straight groove and the two clamping seats are respectively located on both sides of the fixing block, a screw rod rotatably connected to the side plate and one end of the screw rod rotatably connected to the fixing block, the screw rod passing through the clamping seat and threadedly connected to it, and a knob fixedly connected to the end of the screw rod away from the fixing block.

[0006] As a further improvement of this utility model, a right-angle plate is fixedly connected to the base plate on the rear side of the lens mounting seat, and a telescopic rod is fixedly connected to the top of the right-angle plate. The movable shaft of the telescopic rod passes through the top wall of the right-angle plate and is fixedly connected to a grinding device.

[0007] As a further improvement of this utility model, the screw is rotatably connected to the side plate through bearing one, and the end of the screw away from the knob is rotatably connected to the fixing block through bearing two.

[0008] As a further improvement of this utility model, a slider is fixedly connected to the bottom of the clamping seat, and a sliding groove for the slider to slide is provided at the bottom of the straight groove on the lens mounting seat.

[0009] As a further improvement of this utility model, the lens mounting base is provided with multiple small suction holes.

[0010] The beneficial effects of this utility model are as follows: By setting up a double clamping seat structure driven by a screw and moving symmetrically along both sides of the fixing block, combined with the sliding groove guiding mechanism and adsorption auxiliary fixing design on the lens mounting seat, this utility model achieves bidirectional synchronous and stable clamping of optical lenses during processing, with uniform force, accurate positioning and strong vibration resistance. It fundamentally solves the problems of lens displacement, deflection and breakage caused by uneven clamping force or insecure fixing in traditional fixtures, and significantly improves the precision of optical lens processing and the yield of finished products.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0019] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides the following: Figure 1-5 The optical instrument processing fixing device shown includes a base plate 1, a lens mounting seat 2 fixedly connected to the base plate 1, and side plates 3 fixedly connected to both sides of the lens mounting seat 2 on the base plate 1. The lens mounting seat 2 has a straight groove and a fixing block 4 fixedly connected to the lens mounting seat 2 is provided in the straight groove. Two clamping seats 5 are slidably connected to the lens mounting seat 2 at the straight groove and are respectively located on both sides of the fixing block 4. A screw 6 is rotatably connected to the side plate 3 and one end of the screw 6 is rotatably connected to the fixing block 4. The screw 6 passes through the clamping seat 5 and is threadedly connected to it. A knob 7 is fixedly connected to the end of the screw 6 away from the fixing block 4.

[0021] like Figure 1 and Figure 2 As shown, in this utility model, a right-angle plate 8 is fixedly connected to the bottom plate 1 on the rear side of the lens mounting base 2. A telescopic rod 9 is fixedly connected to the top of the right-angle plate 8. The movable shaft of the telescopic rod 9 passes through the top wall of the right-angle plate 8 and is fixedly connected to a grinding device 10. The grinding device 10 can move up and down under the drive of the telescopic rod 9, thereby facilitating the grinding of the lens.

[0022] like Figure 3 As shown, in this utility model, the screw 6 is rotatably connected to the side plate 3 through bearing 11, and the end of the screw 6 away from the knob 7 is rotatably connected to the fixing block 4 through bearing 12, which ensures that the screw 6 can rotate smoothly between the side plate 3 and the fixing block 4, thereby achieving stable driving of the clamping seat 5.

[0023] like Figure 3-5As shown, in this utility model, the bottom of the clamping seat 5 is fixedly connected to a slider 13, and the lens mounting seat 2 is provided with a sliding groove at the bottom of the straight groove for the slider 13 to slide. Through the cooperative design of the slider 13 and the sliding groove, the sliding of the clamping seat 5 on the lens mounting seat 2 is more stable and smooth, further ensuring the precise clamping of the lens.

[0024] like Figure 4 As shown, the lens mounting base 2 of this utility model is provided with multiple small adsorption holes. These small adsorption holes can be used to connect to external adsorption equipment. After the lens is placed on the lens mounting base 2, the adsorption equipment is activated, and adsorption force is generated through the small adsorption holes to help fix the lens and enhance the stability of the lens during the processing.

[0025] Working Principle: In practical implementation, the optical lens is first placed on the lens mounting base 2, positioning it appropriately between the two clamping seats 5. Then, the operator rotates the knob 7, causing the screw 6 to rotate smoothly under the support of bearing 11 and bearing 12. Since the screw 6 is threadedly connected to the clamping seats 5, the rotation of the screw 6 causes the two clamping seats 5 to move symmetrically and smoothly towards the lens along the sliding groove at the bottom of the straight groove on both sides of the fixing block 4 until the lens is gently clamped. During this process, the clamping force can be precisely controlled by adjusting the number of rotations and the force applied by the knob 7, ensuring uniform force on the lens and preventing damage due to excessive local stress.

[0026] Next, the small adsorption holes are connected to and activated by an external adsorption device. The small adsorption holes generate adsorption force to further assist in fixing the lens and enhance its stability during processing, enabling it to better resist vibrations generated during the operation of the processing equipment.

[0027] Once the lens is fixed in place, the grinding equipment 10 can be moved up and down by controlling the extension and retraction of the telescopic rod 9 according to actual processing needs. This allows for key processes such as edge grinding, polishing, coating, or inspection of the lens. During processing, this fixing device effectively maintains the ideal fixed posture of the lens, preventing micro-displacement or deflection, thereby significantly improving processing accuracy and lens yield.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
