[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0029] A cage-type six-axis optical adjustment structure, such as Figures 1 to 3 Shown, including,

[0030] The fixing frame 1 has hand-tightened thread pairs 11 at its three corners;

[0031] The adjustment front plate 2 is located at the front end of the fixing frame 1. A light hole 5 is passed through the center of the adjustment front plate 2 and the fixing frame 1. A sliding block 23 is provided in the adjustment front plate 2.

[0032] The spring piece 3 is provided on a side of the fixing frame 1 close to the adjustment front plate 2;

[0033] The threaded clamp 4 is disposed in the light-through hole 5 of the adjustment front plate 2 and extends toward the front end.

[0034] Specifically, the present invention provides a cage-type six-axis optical adjustment structure, which realizes fixation at any position and provides adjustment and fixation of optical elements in six spatial dimensions. Combined with the leaf spring structure, namely the spring 3, the stability of the optical adjustment structure is improved.

[0035] In a preferred embodiment, the adjustment front plate 2 is further provided with a lens retaining ring 24 and a lens retaining ring 24 located inside the light hole 5;

[0036] The sliding block 23 is located outside the lens retaining ring 24 .

[0037] Specifically, the internal threaded hole inside the light-through hole 5 is used to mount the lens retaining ring 24 and the lens retaining ring retaining ring. Two extrusion threaded holes are also provided at two vertical corners of the sliding block 23 to compress the lens retaining ring 24 so that the lens retaining ring 24 can clamp the lens. The lens retaining ring 24 is used to clamp the lens, and the retaining ring is located on one side of the lens retaining ring 24 to prevent it from falling off.

[0038] More specifically, the hand-tightened thread pair 11 on the fixing frame 1 is a hand-tightened thread pair 11 with a self-locking nut, which can be used to adjust the horizontal and vertical pitch angles of the lens. The lens is clamped in the lens retaining ring 24 and can achieve 360° rotation adjustment.

[0039] In a preferred embodiment, the fixing frame 1 and the adjustment front plate 2 are respectively provided with through holes 6 distributed with the light hole 5 as the center, the spacing between adjacent through holes 6 on the fixing frame 1 is 30 mm, and the spacing between adjacent through holes 6 on the adjustment front plate 2 is 30 mm.

[0040] Specifically, precise adjustment of optical components is possible. The provision of through-holes 6 allows for more precise adjustment, allowing fine-tuning of the position and orientation of the optical components as needed. The mounting bracket 1 provides stable support, ensuring the stability of the optical components during adjustment. The fixed spacing between through-holes 6 ensures uniformity and consistency in the adjustment structure, helping to simplify the adjustment process and improve accuracy and repeatability.

[0041] More specifically, the light hole 5 ensures the transmission and passage of light, ensures the normal propagation of light during the adjustment process of the optical element, and avoids the loss or distortion of optical signals caused by shielding or obstruction.

[0042] In a preferred embodiment, the fixing frame 1 is provided with a first threaded hole 12 for fixing the connecting rod;

[0043] The connecting rod passes through the through holes 6 on the fixing frame 1 and the adjustment front plate 2 and slides back and forth.

[0044] Specifically, the mounting bracket 1 is provided with a first threaded hole 12 for securing the connecting rod. This ensures the connecting rod is firmly fixed, preventing it from loosening or shifting during use, and helping to maintain the stable position of the optical element. The multi-axis adjustment provides greater flexibility and can meet more complex optical adjustment requirements.

[0045] More specifically, by sliding back and forth between the fixing frame 1 and the through hole 6 on the adjustment front plate 2 , a relatively high precision can be achieved, ensuring smooth and accurate adjustment, thereby improving the performance of the optical system.

[0046] In a preferred embodiment, each of the four side surfaces of the fixing frame 1 has a second threaded hole 13 for connecting with a support rod.

[0047] Specifically, by providing second threaded holes 13 for connecting support rods on the four sides of the fixing frame 1, more support points and stability can be provided, and the fixing frame 1 can be connected from multiple directions, making the adjustment process more flexible and comprehensive.

[0048] More specifically, by providing second threaded holes 13 on multiple sides of the fixing frame 1, uniform load distribution on the support rod can be achieved, which helps to reduce the pressure on a single connection point, reduces the stress concentration of the structure, and enhances the stability and durability of the structure.

[0049] In a preferred embodiment, two side surfaces of the adjustment front plate 2 are provided with countersunk holes 21 for installing self-locking non-hand-tightening thread pairs, and the other two side surfaces are provided with third threaded holes 22 for installing screws.

[0050] Specifically, vertical and horizontal adjustment threaded pairs are provided on the side of the adjustable front plate 2. The use of countersunk holes 21 or third threaded holes 22 simplifies the installation and removal of the adjustable front plate 2. During installation, the use of self-locking, non-tightening threaded pairs or screws allows for faster securing of the adjustable front plate 2, while allowing for easy removal during removal.

[0051] More specifically, since the adjustment front plate 2 is firmly fixed, the position and direction of the optical element can be kept stable during the adjustment process, which helps to improve the accuracy and reliability of the adjustment and ensure that the performance of the optical system reaches the expected level.

[0052] In a preferred embodiment, an adjustment spring 26 is provided between the third threaded hole 22 and the sliding block 23 , and the adjustment spring 26 is used to provide elastic force in the horizontal and vertical directions.

[0053] In a preferred embodiment, countersunk holes for assembling hand-tightened thread pairs 11 are further provided on the three corners of the fixing frame 1 .

[0054] Specifically, by assembling the hand-tightened thread pair 11 through the countersunk hole, loosening or deviation between the fixing frame 1 and the adjustment front plate 2 can be effectively prevented, which helps to maintain the stability of the optical element.

[0055] In a preferred embodiment, a spring locking hole 31 is provided on the spring 3 .

[0056] Specifically, the spring plate locking hole 31 can be used to fix the position of the spring plate 3 on the adjustment front plate 2. By locking the spring plate 3, it can be ensured that the spring plate 3 will not accidentally move or loosen during use, thereby enhancing the stability and reliability of the entire optical adjustment structure.

[0057] In a preferred embodiment, a metal cover plate 25 for pressing the lens and the sliding block 23 is further provided inside the adjustment front plate 2 .

[0058] Specifically, the metal cover 25 can provide an additional layer of protection to ensure that the lens and the sliding block 23 are in a safe state and not susceptible to external damage. It can also effectively fix these components to prevent them from moving or swinging during use, thereby extending the service life of the entire optical adjustment structure.

[0059] In the first embodiment, a cage-type six-axis optical adjustment mount includes a fixed frame 1 and an adjustable front plate 2. A light hole 5 extends through the center of the fixed frame 1 and the adjustable front plate 2. Four through holes 6 are distributed around the light hole 5, with equal center distances between each pair. The through holes 6 are spaced 30 mm apart, allowing a connecting rod to slide back and forth through the through holes 6. Each through hole 6 has two mutually perpendicular threaded holes for securing the fixed frame 1 to the connecting rod. A countersunk hole is provided at each of the three corners of the fixed frame 1 for assembling a self-locking hand-tightened threaded pair 11 and a self-locking non-hand-tightened threaded pair, respectively. A threaded hole is provided on each of the four side surfaces of the fixed frame 1 for connection to a conventional support rod.

[0060] The front adjustment plate 2 has a central aperture 5 and a square recessed platform for mounting a slide block 23. Each of the four corners of the recessed platform has a circular through-hole 6 to avoid the passage of the connecting rod. Also located on the vertical surface of the front adjustment plate 2 are two round threaded holes for screws and two round countersunk holes for mounting self-locking, non-tightening threaded pairs.

[0061] The center of the slider 23 features a large, transparent internally threaded hole for mounting the lens retaining ring 24 and its retaining ring. Two additional threaded holes, located at two vertical corners of the slider 23, compress the lens retaining ring 24, securing it against the lens. The retaining ring is located on one side of the lens retaining ring 24 to prevent it from falling off. A hand-tightened threaded pair 11 with a self-locking nut is used to adjust the horizontal and vertical pitch angles of the lens. The lens is secured within the lens retaining ring 24 and can be rotated 360°.

[0062] In summary, the present application provides a cage-type six-axis optical adjustment structure, which can be slid to any position in the direction of the optical axis and then fixed, so as to realize the pitch angle adjustment of the fixed object and the adjustment of the horizontal and vertical directions perpendicular to the optical axis, as well as the rotation adjustment of any angle perpendicular to the optical axis. Combined with the design of the spring 3, it can be applied to high-stability related test equipment.

[0063] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
