Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical lenses, in particular to a lens clamping device for a laser bomb disposal system with fine-tunable optical axis. Background Art
[0002] An optical lens is a crucial optical component in laser bomb disposal systems. Made of transparent material, it operates by utilizing the laws of light refraction. Its refractive surfaces are either two spherical surfaces or a spherical surface and a flat surface. When light passes obliquely from one medium into another, its propagation direction changes, causing the light to be deflected at the interface between the two media. Through its unique shape and material, the lens refracts light as it passes through it, achieving focusing and diverging effects.
[0003] Optical lenses are widely used in laser-based destruction systems, such as laser bomb disposal and laser counter-drone (UAV) systems. The laser light path in these systems uses a combination of multiple lenses to control and focus the beam. Due to structural errors in the system, there is often a slight angular deviation between the optical axis of the optical lens and the designed optical axis. When striking targets more than 100 or 200 meters away, this deviation is magnified by the distance, resulting in a significant deviation between the center of the aiming crosshairs determined by the operator and the actual impact point. This makes it impossible to accurately aim at the impact point when destroying obsolete ammunition, and in severe cases, the target may be missed.
[0004] Fine-tuning the tilt angle of an optical lens requires extremely high precision. Because the focusing quality of a laser bomb disposal system is extremely sensitive to the position and angle of the lens, even small angular deviations can lead to a significant decrease in focusing quality and a large deviation in the focus position. Therefore, during the fine-tuning process, high-precision measurement and adjustment equipment, such as optical collimators and autocollimators, are required to ensure the accuracy of the adjusted angle. However, these instruments are difficult to integrate into a laser bomb disposal system due to their structure and size. Therefore, a lens clamping device with easy adjustment, compact size, and fine-tunable optical axis is urgently needed. Utility Model Content
[0005] In order to solve the usability problem of current optical lenses in use, the utility model proposes a lens clamping device for a laser bomb disposal system with fine-tunable optical axis, comprising a rectangular lens support, a lens fixedly arranged in the center of the rectangular lens support, and further comprising:
[0006] The lens fixture base is a quadrangular cylinder with a first light hole at the center of the bottom plate. Multiple axial spring plates are fixed to the bottom plate on the side of the first light hole, and one or more radial spring plates are fixed to each side of the inner side wall. The rectangular lens support is disposed inside the lens fixture base and supports the rectangular lens support in three directions. Multiple first adjustment holes are evenly distributed on each side of the side wall of the rectangular lens support.
[0007] The lens fixture cover is a rectangular cover that is fixedly set on the top of the lens fixture base. A second light hole is opened at the center of the lens fixture cover, and second adjustment holes are set at the four corners of the lens fixture cover. The first adjustment hole and the second adjustment hole are used to adjust the micro-displacement and tilt angle of the rectangular lens support by setting adjustment bolts.
[0008] As a preferred solution, the axial spring piece is an arched spring piece, and an axial spring piece is provided at each of the four corners of the bottom plate of the lens fixture base.
[0009] As a preferred solution, the radial spring pieces are arched spring pieces, and two radial spring pieces are provided on each side of the side wall of the rectangular lens support, and the two radial spring pieces are symmetrically arranged about the side midline.
[0010] As a preferred solution, the number of the first adjustment holes on each side is 3, and the middle first adjustment hole is arranged on the side midline.
[0011] As a preferred solution, second adjustment holes are also provided in the middle of the four sides of the lens fixture cover.
[0012] As a preferred solution, the difference between the distance between the two opposite side walls of the lens fixture base and the side length of the rectangular lens support is no more than 2 / 3 of the radial spring sheet deformation height.
[0013] As a preferred solution, the first light hole, the second light hole and the lens are coaxially arranged.
[0014] The beneficial effects of the utility model are:

In a high-precision laser damage system, it can significantly improve the overall performance of the optical system. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] To illustrate the features of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Example 1:
[0024] See also Figures 1 to 3 The present invention provides a lens clamping device for a laser bomb disposal system with fine-tunable optical axis, comprising a lens 421 and a rectangular lens holder 42, wherein the lens 421 is fixedly disposed in the center of the rectangular lens holder 42, and further comprising:
[0025] The lens clamp base 41 is a square cylinder as a whole, with a first light hole 414 opened at the center of the bottom plate. A plurality of axial spring pieces 412 are fixedly set on the bottom plate on the side of the first light hole 414. The axial spring pieces 412 are arched spring pieces. An axial spring piece 412 is set at each of the four corners of the bottom plate of the lens clamp base 41, so that the spring supports the lens more comprehensively and avoids some areas from being unable to rebound.
[0026] One or more radial spring pieces 411 are fixedly provided on each side of the inner side wall. The radial spring pieces 411 are arched spring pieces. Two radial spring pieces 411 are provided on each side of the side wall of the rectangular lens support 42. The two radial spring pieces 411 are symmetrically arranged about the side midline. The symmetrical arrangement of the two radial spring pieces 411 can achieve adjustment of two variables: distance and tilt angle. The rectangular lens support 42 is provided inside the lens fixture base 41 and supports the rectangular lens support 42 in two directions. The radial spring pieces 411 and the axial spring pieces 412 achieve more three-dimensional support for the lens, providing the lens 421 with adjustment space at multiple angles. Multiple first adjustment holes 413 are evenly distributed on each side of the side wall of the rectangular lens support 42.
[0027] The lens holder cover plate 43 is a rectangular cover plate fixedly mounted on the top of the lens holder base 41. A second aperture 432 is defined at the center of the lens holder cover plate 43. Second adjustment holes 431 are defined at each of the four corners of the lens holder cover plate 43. The first adjustment holes 413 and the second adjustment holes 431 are configured to adjust the tilt angle of the rectangular lens holder 42 via adjustment bolts. Specifically, in this embodiment, there are three first adjustment holes 413 on each side. The middle first adjustment hole 413 is located on the side midline. The adjustment bolts on both sides can adjust the radial deflection angle of the rectangular lens holder 42, while the adjustment bolt on the middle midline can adjust the eccentric displacement of the rectangular lens holder 42 with a single bolt. In this embodiment, second adjustment holes 431 are also defined in the middle of each of the four sides of the lens holder cover plate 43. The middle second adjustment holes 431 are configured to deflect the entire lens holder cover plate 43 in one direction without having to adjust the adjustment bolts at both ends simultaneously. The addition of adjustment points in the middle significantly simplifies the adjustment operation.
[0028] This embodiment also offers improved adaptability during use. To fully utilize the elastic force of the radial spring piece 411, the difference between the distance between the opposing side walls of the lens holder base 41 and the side length of the rectangular lens support 42 is set equal to two-thirds of the deformation height of the radial spring piece 411. This ensures sufficient elastic force generated by the deformation of the spring piece 411. The same treatment applies to the axial spring piece 412. Furthermore, to enhance optical axis alignment efficiency, this embodiment arranges the first and second optical holes 414, 432 coaxially with the lens 421, significantly improving the focusing quality and accuracy of the output light beam.

The present invention has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions, or substitutions made by those skilled in the art within the spirit of the present invention do not depart from the spirit of the present invention and are intended to fall within the scope of the claims of the present invention.
