Description

A quick-change universal optical adjustment frame device and optical instrument Technical Field

[0001] This invention relates to the field of optical equipment, and more specifically, to a quick-change universal optical adjustment bracket device and an optical instrument. Background Technology

[0002] Optical adjustment frames, as core components in optical instruments, scientific research experiments, and industrial inspection, primarily function to reliably fix and adjust the attitude of optical lenses, ensuring precise matching of optical paths and directly impacting the operational stability and detection accuracy of the entire optical system. With the continuous development of optical technology, various optical application scenarios place higher demands on the adaptability, adjustment flexibility, and ease of operation of adjustment frames. Different experimental or operational conditions often require switching between lenses of different sizes, and there are diverse needs for the spatial angle adjustment range and accuracy of the lenses.

[0003] Currently, optical adjustment frames on the market have significant functional limitations: On the one hand, most existing frames adopt a fixed design of "one lens fits one frame," lacking a quick-change lens design. When different sizes of lenses need to be changed, the entire frame must be disassembled and replaced, which is not only cumbersome and time-consuming, but also causes the installation reference to shift due to frequent disassembly and assembly, affecting optical accuracy, and increasing equipment procurement and maintenance costs. On the other hand, although some adjustment frames have angle adjustment functions, most can only achieve single-direction or limited angle adjustment, which cannot meet the requirements of omnidirectional (such as 360° X-axis and Z-axis) adjustment and reliable fixation within a spatial range, making it difficult to adapt to the posture adjustment requirements of complex optical systems. In addition, existing adjustable frames generally lack a switching structure between coarse and fine adjustment, making it difficult to balance efficiency and accuracy during adjustment. Either the adjustment speed is slow, or high-precision positioning cannot be achieved, which restricts their application in high-precision optical scenarios. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] The first embodiment refers to Figures 1 to 5. This embodiment provides a quick-change universal optical adjustment frame device, including a frame, which includes a frame body 1, a sub-frame 2, a fixing ring 3, a first fixing member 4, and a second fixing member 5. The frame body 1 has a first stepped hole 6 in the middle, which matches the size of the first lens, allowing selective installation of the first lens or the sub-frame 2 to achieve adaptation and switching between lenses of different sizes. The sub-frame 2 has a second stepped hole 7, which is the same size as the second lens, used to simultaneously install the second lens and the fixing ring 3. After assembly, the second lens is located between the fixing ring 3 and the second stepped surface of the second stepped hole 7. The fixing ring 3 is detachably located in the second stepped hole 7. During installation, the axial pressing action of the fixing ring 3 ensures that the second lens is tightly fitted to the second stepped surface, guaranteeing the installation of the second lens. Positioning accuracy; The top of the frame body 1 is provided with a first fixing hole 8, which is a through hole extending downward in the vertical direction and connected to the first mounting hole (i.e., the mounting area of ​​the first stepped hole 6). The first fixing member 4 is installed in the first fixing hole 8, and its inner end extends into the first mounting hole by a set length. When the first lens is directly installed in the first mounting hole, the inner end of the first fixing member 4 contacts the non-mirror part of the first lens. By applying pressure, the first lens is pressed and fixed in the first mounting hole to prevent the lens from loosening. One end of the second fixing member 5 is detachably connected to the frame body 1, and the other end is pressed on the outer side of the sub-frame 2. By this pressing force, the inner side of the sub-frame 2 is tightly attached to the first stepped surface of the first stepped hole 6, so as to achieve reliable fixation of the sub-frame 2, and at the same time facilitate the disassembly of the sub-frame 2 to switch the installation of the first lens. When a second lens (such as a φ36mm lens) is needed, the second lens is placed into the second step hole 7 of the sub-frame 2, ensuring the lens fits against the second step surface. The retaining ring 3 is then fitted into the second step hole 7 and locked. The sub-frame 2 is then placed into the first step hole 6 of the frame body 1 and secured by the second fixing member 5. When switching to the first lens (such as a φ50.8mm lens), the second fixing member 5 is removed, and the sub-frame 2 is taken out. The first lens is placed into the first step hole 6 and secured by the first fixing member 4, allowing for quick and non-destructive switching between the two lens types. Simultaneously, the frame can be adjusted in multiple directions to meet different usage needs. The detachable assembly design of the frame body 1 and the sub-frame 2 enables quick lens replacement of different sizes without replacing the entire frame, improving equipment versatility and efficiency. The first fixing member 4 and the second fixing member 5 secure the lens or sub-frame 2 in different installation states, ensuring installation stability and positioning accuracy, and preventing lens displacement during use that could affect optical performance.

[0026] In a preferred embodiment, the first stepped hole 6 includes a first large hole and a first small hole. The inner diameter of the first large hole matches the outer diameter of the first lens or the outer diameter of the sub-frame 2, and is used to install the first lens or the sub-frame 2. The first large hole and the first small hole are connected by a first stepped surface, which is precision machined to ensure high flatness and perpendicularity, and serves as the axial positioning reference surface for the sub-frame 2 or the first lens. The second stepped hole 7 includes a second large hole and a second small hole. The inner diameter of the second large hole is adapted to the outer diameter of the second lens and the outer diameter of the retaining ring 3, and is used to install the retaining ring 3 and the second lens simultaneously. The second large hole and the second small hole are connected by a second stepped surface, which provides precise axial support for the second lens.

[0027] Furthermore, the inner surface of the second large hole is provided with internal threads, and the outer surface of the fixing ring 3 is provided with external threads. The two are connected by threads to achieve detachable assembly. By rotating the fixing ring 3, its axial position in the second large hole can be adjusted, thereby precisely controlling the clamping force on the second lens. When installing the second lens, the edge of the second lens is placed in the second large hole and fits against the second step surface. The fixing ring 3 is screwed into the internal thread of the second large hole through its external threads. As the fixing ring 3 is screwed in, its end face gradually applies axial pressure to the second lens, making the second lens firmly pressed against the second step surface. At the same time, the threaded connection has self-locking properties, which can initially prevent the fixing ring 3 from loosening. When installing the sub-frame 2 or the first lens, the first step surface of the first large hole provides stable support, ensuring that the coaxiality and flatness after assembly meet the requirements of the optical system. The first and second small holes serve as light transmission channels in their respective installation states, avoiding obstruction of the effective optical area of ​​the lens.

[0028] In a preferred embodiment, the second fixing member 5 includes a fixing part 501 and a pressing part 502. The fixing part 501 has a bolt hole, and the fixing part 501 is detachably fixed to the preset installation position of the frame body 1 by passing a bolt through the bolt hole, so as to ensure the stability of the second fixing member 5 after installation. One end of the pressing part 502 is perpendicularly connected to the fixing part 501, and the other end extends to the outer side of the sub-frame 2. The end of the pressing part 502 is provided with a fitting surface adapted to the outer side of the sub-frame 2, so that the pressing part 502 can be smoothly pressed onto the outer side of the sub-frame 2. After the sub-frame 2 is installed into the first large hole of the frame body 1 and fits against the first stepped surface, the fixing part 501 of the second fixing member 5 is fixed to the frame body 1 with bolts. At this time, the contact surface of the pressing part 502 is in close contact with the outer side of the sub-frame 2. The locking force of the bolt is converted into the axial pressure of the pressing part 502 on the sub-frame 2, so that the inner side of the sub-frame 2 always fits against the first stepped surface, realizing the circumferential and axial positioning of the sub-frame 2. When it is necessary to disassemble the sub-frame 2, loosen the bolts and remove the second fixing member 5, and the sub-frame 2 can be taken out directly, which is convenient.

[0029] In a preferred embodiment, the adjustment bracket 22 and the frame body 1 are rotatably connected. When a driving force in the first direction and / or the second direction is applied to the frame body 1, the frame body 1 can rotate along the first direction and / or the second direction, thereby adjusting the angle of the first lens or the second lens mounted on the frame body 1 to meet the needs of different optical paths. The first direction and the second direction are perpendicular to each other (corresponding to two orthogonal directions in the spatial coordinate system, such as the horizontal direction and the vertical direction).

[0030] Furthermore, the adjustment bracket 22 provides a stable mounting base for the frame body 1. By applying force through a drive mechanism or manually, the frame body 1 rotates around a pivot in the first direction, achieving lens angle adjustment in that direction. Similarly, when a force is applied along the second direction, the frame body 1 rotates around a pivot in the second direction, achieving angle adjustment in the other direction. When driving forces are applied simultaneously in both directions, composite lens angle adjustment can be achieved, ultimately allowing the lens to be adjusted to any desired angle within the spatial range. The addition of the adjustment bracket 22 enables the device to have omnidirectional angle adjustment capabilities, solving the problem of limited angle adjustment in traditional frames and expanding the device's applicable scenarios. The perpendicular design of the first and second directions ensures the independence and precision of angle adjustment, facilitating directional adjustment by users according to actual needs and improving the device's operational flexibility and practicality.

[0031] In a preferred embodiment, the adjustment bracket 22 includes a fixed base 9, a fixed bracket 10, a horizontal rotating shaft assembly, and a vertical rotating shaft assembly. The fixed base 9 provides bottom support, and its structural design ensures stability after installation. The fixed bracket 10 is rotatably disposed inside the fixed base 9. The horizontal rotating shaft assembly includes at least two first rotating shafts 11 with horizontal axes. The two first rotating shafts 11 are coaxially arranged and rotatably disposed on opposite inner sides of the fixed bracket 10 via bearings. The inner ends of the first rotating shafts 11 are fixedly connected to the outer side wall of the frame body 1, so that the frame body 1 can rotate around the first rotating shafts 11 (corresponding to the first direction). The vertical rotating shaft assembly includes a second rotating shaft 12 with a vertical axis. The second rotating shaft 12 is fixedly disposed on the top surface of the fixed bracket 10, and the top end of the second rotating shaft 12 is fixedly connected to the bottom surface of the frame body. By rotating the fixed bracket 10, the second rotating shaft 12 and the frame body 1 can be driven to rotate along the vertical axis.

[0032] When the lens angle needs to be adjusted along the first direction (horizontal direction), the frame body 1 rotates around two coaxial first rotating shafts 11. Since the first rotating shafts 11 are connected to the fixed bracket 10 through bearings, the rotation process is smooth and highly accurate. At the same time, the symmetrical arrangement of the two first rotating shafts 11 ensures that the frame body 1 is subjected to balanced force and avoids deviation during rotation. When the angle needs to be adjusted along the second direction (vertical direction), the frame body 1 rotates around the vertical axis. The vertical arrangement of the second rotating shaft 12 ensures that the rotation trajectory is a horizontal circle, realizing the angle adjustment of the lens in the vertical plane. The cooperation between the horizontal rotating shaft assembly and the vertical rotating shaft assembly enables the frame body 1 to rotate at any angle in space, fully meeting the needs of universal adjustment.

[0033] In a preferred embodiment, a first adjustment component is provided on the fixed bracket 10 to achieve precise adjustment of the frame body 1 along a first direction. A mounting base is provided at one end of the side of the fixed bracket 10. The first adjustment component includes a first threaded sleeve 13 and a first threaded rod 14. The first threaded sleeve 13 is fixedly disposed within the mounting base, and its axial direction is perpendicular to the axial direction of the first rotating shaft 11. The first threaded rod 14 is connected to the first threaded sleeve 13 via a threaded pair and can move along the axial direction of the first threaded sleeve 13. A first adjustment arm 17 extends outward from one side of the frame body 1. The first adjustment arm 17 is located inside the fixed bracket 10, and one side of the first adjustment arm 17 abuts against one end of the first threaded rod 14. The contact area between the two is designed with a smooth surface to reduce friction during adjustment.

[0034] When the frame body 1 needs to be adjusted in the first direction, the first threaded rod 14 is rotated. Since the first threaded rod 14 is threadedly connected to the first threaded sleeve 13, the threaded transmission converts the rotational motion into axial linear motion, causing the first threaded rod 14 to move along the axial direction and push the first adjusting arm 17. The first adjusting arm 17 drives the frame body 1 to rotate around the first rotating shaft 11, thereby realizing the adjustment of the lens angle. By controlling the number of rotations of the first threaded rod 14, the rotation angle of the frame body 1 can be precisely controlled, achieving fine adjustment. The first adjusting component adopts a threaded transmission structure, which has the characteristics of good self-locking and high adjustment accuracy, enabling precise fine adjustment of the angle of the frame body 1, meeting the requirements of high-precision optical systems. The design of the first adjusting arm 17 provides a reliable carrier for the transmission of adjustment force, allowing the adjustment force to be applied evenly to the frame body 1, avoiding structural deformation or adjustment errors caused by localized forces.

[0035] In a preferred embodiment, the other end of the side of the fixed bracket 10 is provided with a mounting seat symmetrical to the first adjusting component. The second adjusting component includes a second threaded sleeve 15 and a second threaded rod 16. The second threaded sleeve 15 is fixedly disposed in the mounting seat, and its axis is collinear with the axis of the first threaded sleeve 13. The second threaded rod 16 is connected to the second threaded sleeve 15 through a threaded pair and can move along the axial direction of the second threaded sleeve 15. The fixed bracket 10 is provided with a second adjusting arm 18 extending horizontally, and one side of the second adjusting arm 18 abuts against one end of the second threaded rod 16, which is consistent with the contact structure of the first adjusting arm 17 and the first threaded rod 14.

[0036] When it is necessary to rotate the frame body 1 towards the second adjustment component, the second threaded rod 16 is rotated. The second threaded rod 16 moves along the axial direction and pushes the second adjustment arm 18, causing the frame body 1 to rotate around the vertical axis. When it is necessary to rotate the frame body 1 towards the first adjustment component, the first threaded rod 14 is rotated. By adjusting the positions of the first threaded rod 14 and the second threaded rod 16 respectively, bidirectional angle adjustment of the frame body 1 along the first direction can be achieved. Moreover, due to the symmetrical arrangement of the two adjustment components, the adjustment process is more stable. The addition of the second adjustment component makes the angle adjustment of the frame body 1 more flexible, and bidirectional adjustment can be achieved without relying on a reverse force, making operation more convenient. The symmetrical design ensures that the frame body 1 is subjected to balanced force, further improving the adjustment accuracy and structural stability. At the same time, the self-locking property of the threaded drive ensures that the adjusted angle can be stably maintained, avoiding angle deviation due to vibration or other factors.

[0037] In a preferred embodiment, the first spring 19 is located on the side of the first adjusting arm 17 away from the first threaded rod 14, with one end fixedly connected to the inner wall of the fixed bracket 10 and the other end abutting against the side of the first adjusting arm 17, and the first spring 19 is in a pre-compressed state; the second spring 20 is located on the side of the second adjusting arm 18 away from the second threaded rod 16, with one end fixedly connected to the inner wall of the fixed bracket 10 and the other end abutting against the side of the second adjusting arm 18, and is also in a pre-compressed state. When the first threaded rod 14 is rotated to push the first adjusting arm 17, the first adjusting arm 17 compresses the first spring 19, and the first spring 19 generates a reverse elastic force. This elastic force balances the thrust of the first threaded rod 14, allowing the frame body 1 to remain stably at the adjusted angle. When the first threaded rod 14 is rotated in the opposite direction, the elastic force of the first spring 19 pushes the first adjusting arm 17 to reset, causing the frame body 1 to rotate in the opposite direction. This eliminates the need for manual pulling, making operation easier. Similarly, when adjusting the second threaded rod 16, the second spring 20 plays the same reset and buffering role. At the same time, the two pre-compressed springs always apply pressure to the first adjusting arm 17 and the second adjusting arm 18, ensuring that the adjusting arm and the corresponding threaded rod always maintain close contact, avoiding adjustment play caused by gaps and improving adjustment accuracy. The addition of springs not only provides a restoring force for the adjustment process and simplifies the operation, but also reduces the impact force during adjustment through elastic buffering, protecting the structure of the frame body 1 and the adjustment components. The pre-compression design ensures reliable contact between the adjustment arm and the threaded rod, eliminates adjustment backlash, and further improves the accuracy and stability of angle adjustment, making the device more suitable for high-precision optical applications.

[0038] In a preferred embodiment, the inner wall of the first fixing hole 8 is provided with an internal thread, and the outer wall of the first fixing member 4 is provided with an external thread. The two are connected by threads to achieve detachable assembly. The length of the inner end of the first fixing member 4 extending into the first mounting hole is adjusted by the thread insertion depth, thereby precisely controlling the clamping force on the first lens. When adjusting the frame body 1 to rotate in the second direction, the bottom surface of the frame body 1 rotates with the second rotating shaft 12. The user can read the rotation angle through the scale 21 on the side of the fixing seat 9 to achieve visual adjustment of the angle without the need for additional measuring tools. When installing the first lens, the first fixing member 4 is screwed into the first fixing hole 8, and its insertion length is adjusted by the thread drive so that the inner end just abuts against the non-mirror part of the first lens and applies a suitable clamping force. After tightening, the self-locking property of the threaded connection ensures that the first fixing member 4 will not loosen, thereby ensuring the stable installation of the first lens. When disassembling, the first fixing member 4 can be removed by rotating it in the opposite direction, which is convenient.

[0039] The second embodiment, referring to Figure 2, provides an optical instrument comprising the quick-change universal optical adjustment frame device described in any one of the first embodiments, an optical main body, a light source assembly, and a detection assembly. The quick-change universal optical adjustment frame device is detachably mounted on a preset position of the optical main body via a fixing seat 9 of an adjustment bracket. The light source assembly and the detection assembly are respectively located on both sides of the quick-change universal optical adjustment frame device, and their central axes are collinear, ensuring that light can sequentially pass through the light source assembly, the lens on the adjustment frame device, and the detection assembly to form a complete optical path. The working principle of this optical instrument is as follows: according to actual usage requirements, a lens of appropriate size (first lens or second lens) is switched and installed via the quick-change universal optical adjustment frame device, and the angle of the lens is adjusted by the adjustment bracket, so that the light emitted by the light source assembly is accurately incident on the detection assembly after refraction, reflection, or transmission by the lens, and the detection assembly detects and analyzes the light. During use, the lens angle can be finely adjusted via the first adjustment assembly, the second adjustment assembly, and the vertical rotating shaft assembly according to the adjustment requirements of the optical path to ensure detection accuracy. This embodiment integrates all the advantages of a quick-change universal optical adjustment frame device, enabling rapid switching between lenses of different sizes and precise universal adjustment of lens angles, thus improving the versatility and adaptability of optical instruments. It eliminates the need for dedicated instruments for lenses of different sizes, reducing equipment costs. The precision and stability of angle adjustment ensure the detection accuracy of optical instruments, making it suitable for various high-precision optical applications such as scientific research and industrial testing.
