Description

Technical Field

[0001] This utility model relates to the field of optical experimental system technology, and in particular to a two-stage adjustment operator. Background Technology

[0002] In the construction and debugging of precision optical experimental systems, it is crucial to accurately control the spatial position (displacement) and orientation angle (rotation) of optical components (such as lenses, mirrors, polarizers, beam splitters, gratings, etc.). These fine adjustments directly affect the collimation of the optical path, beam quality, interference fringe contrast, measurement resolution, and the accuracy and reliability of the final experimental results.

[0003] To meet the needs of different adjustment stages, optical adjustment devices (such as displacement stages, rotary stages, and combinations thereof) are typically designed with two levels of adjustment: coarse adjustment and fine adjustment. Coarse adjustment is used to achieve rapid positioning of the component's position or angle over a wide range, while fine adjustment is responsible for making subtle and precise corrections based on the coarse adjustment positioning to achieve the high precision requirements of the experiment. Currently, coarse and fine adjustment modules are mostly designed independently (e.g., coarse adjustment is achieved through a spiral slide, and fine adjustment is achieved through piezoelectric ceramics or differential screws). The two are assembled by stacking them together through mechanical connectors, resulting in a relatively large overall transmission structure. Utility Model Content

[0004] In view of this, this utility model proposes a two-stage adjustment operator, which aims to achieve a compact structure for coarse and fine adjustment and reduce the overall size.

[0052] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0053] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0054] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0055] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0056] refer to Figures 1 to 7 One embodiment of this utility model shows a two-stage adjustment operator, including a fixed cylinder 1, a first rotating shaft 2, a second rotating shaft 3, a first rotating wheel 4, and a second rotating wheel 5;

[0057] The fixed cylinder 1 is fixedly installed; the first rotating shaft 2 is rotatably sleeved inside the fixed cylinder 1, the first rotating shaft 2 is an axially hollow structure, and one end of the first rotating shaft 2 is provided with a first circumferential transmission part 21; the second rotating shaft 3 is sleeved inside the first rotating shaft 2, and the second rotating shaft 3 and the first rotating shaft 2 are relatively fixed in the circumferential direction; the first rotating shaft 2 is coaxially rotatably installed at one end of the fixed cylinder 1, the first rotating wheel 4 is provided with a gear set 41, the first rotating wheel 4 is fixedly connected to the second rotating shaft 3, and the first end of the transmission path of the gear set 41 meshes with the first circumferential transmission part 21; the second rotating shaft 3 is coaxially rotatably installed on the first rotating wheel 4, and the second rotating wheel 5 is provided with a second circumferential transmission part 51, and the second circumferential transmission part 51 meshes with the second end of the transmission path of the gear set 41.

[0058] Specifically, since the first rotating wheel 4 is fixedly connected to the second rotating shaft 3, and the second rotating shaft 3 and the first rotating shaft 2 are relatively fixed in the circumferential direction, when the first rotating wheel 4 is rotated, the first rotating wheel 4 will synchronously drive the second rotating shaft 3 to rotate, and the second rotating shaft 3 will synchronously drive the first rotating shaft 2 to rotate. The first rotating shaft 2 outputs rotation amount to achieve coarse adjustment.

[0059] When the second rotating wheel 5 is rotated, the second circumferential transmission part 51 on the second rotating wheel 5 drives the first circumferential transmission part 21 on the first rotating shaft 2 to rotate through the gear set 41. The gear set 41 achieves a high transmission ratio and stable transmission, which can refine the rotation output of the first rotating shaft 2 and achieve fine adjustment.

[0060] The two-stage adjustment manipulator 100 integrates the coarse and fine adjustment transmission structures into a single shaft system through a nested rotating shaft structure (fixed cylinder 1, first rotating shaft 2, and second rotating shaft 3 coaxially connected). Simultaneously, the first rotating wheel 4 and the second rotating wheel 5 are positioned at one end of this shaft system, with a gear set 41 built into the first rotating wheel 4. The first rotating wheel 4 can directly drive the second rotating shaft 3 to rotate synchronously with the first rotating shaft 2, achieving rapid positioning over a wide range for coarse adjustment. The second rotating wheel 5 can drive the first rotating shaft 2 to rotate independently via the gear set 41, achieving high-precision correction for fine adjustment. This two-stage adjustment manipulator 100 deeply integrates the coarse and fine adjustment transmission structures into one unit, significantly reducing its size and improving space utilization.

[0061] In some embodiments, to facilitate the rotational connection between the fixed cylinder 1 and the first rotating shaft 2, such as... Figure 4 As shown, one end of the fixed cylinder 1 is provided with an annular guide wheel portion 11 protruding radially; the first rotating wheel 4 is provided with a rotating chamber 45 for the annular guide wheel portion 11 to be inserted, and the side wall of the rotating chamber 45 is provided with a rotating hole 46 that is rotatably connected to the fixed cylinder 1, and the diameter of the rotating hole 46 is smaller than the width of the annular guide wheel portion 11.

[0062] The rotating chamber 45 on the first rotating wheel 4 can limit the annular guide wheel portion 11 of the fixed cylinder 1 within a certain range, so that the first rotating wheel 4 and the fixed cylinder 1 will not separate axially.

[0063] It is worth noting that the structure in which the first rotating wheel 4 and the fixed cylinder 1 can rotate relative to each other in the circumferential direction while remaining relatively stable in the axial direction can refer to existing technologies.

[0064] For ease of assembly, the first rotating wheel 4 can be composed of multiple parts; one embodiment is as follows: Figure 4 As shown, the first rotating wheel 4 includes a rotating wheel body 42, a gear frame 43, and a pressure cover 44; the gear frame 43 is fixedly disposed inside the rotating wheel body 42, and the gear set 41 is disposed on the gear frame 43; the pressure cover 44 is installed on one side of the gear frame 43, and the rotating chamber 45 is formed between the pressure cover 44 and the gear frame 43; the rotating hole 46 is disposed on the pressure cover 44, and one end of the second rotating shaft 3 is fixedly connected to the gear frame 43.

[0065] It should be noted that the above-mentioned fixed connection refers to the relative fixation between two components, such as by using screws or other parts to achieve a fixed connection.

[0066] In some implementations, such as Figure 1 and Figure 7 As shown, it also includes a locking member 6. The fixed cylinder 1 is provided with an external threaded connection part 13, and the locking member 6 is threadedly connected to the external threaded connection part 13. By rotating the locking member 6, one end of the locking member 6 can be pressed against the first rotating wheel 4.

[0067] When the first rotating wheel 4 is adjusted to the correct position, the locking member 6 can be rotated. The locking member 6 will move along the axial direction of the fixed cylinder 1, and one end of the locking member 6 will press against the first rotating wheel 4, increasing the rotational resistance between the first rotating wheel 4 and the locking member 6, making it difficult for the first rotating wheel 4 to rotate and keeping its position fixed. In this way, the position of the first rotating wheel 4 is locked.

[0068] In some embodiments, the first rotating shaft 2 can be connected to a rotating body (not shown). When the first rotating wheel 4 or the second rotating wheel 5 is rotated, the first rotating shaft 2 outputs a rotation amount, which is then transmitted to the rotating body to achieve rotational adjustment of the rotating body. The rotating body can be a rotating platform on which optical elements are mounted.

[0069] In some implementations, the rotational amount output by the first rotating shaft 2 can also be converted into a linear displacement; such as Figure 1 and Figure 7 As shown, a window 12 is provided on the side wall of the fixed cylinder 1; a third circumferential transmission part 22 is provided on the first rotating shaft 2, and the position of the third circumferential transmission part corresponds to the window 12.

[0070] like Figures 8 to 10 As shown, the two-stage adjustment manipulator 100 is applied to a cargo-carrying moving platform. The platform includes a base 200 and a movable body 300 slidably mounted on the base 200. The movable body 300 is provided with a transmission rack 301 arranged along the sliding direction. The fixed cylinder 1 is fixedly mounted on the base 200, and the third circumferential transmission part 22 meshes with the transmission rack 301. Thus, when the first rotating shaft 2 outputs rotation, the third circumferential transmission part 22 rotates, thereby driving the movable body 300 to slide via the transmission rack 301.

[0071] In some implementations, such as Figures 11 to 13 As shown, the two-stage adjustment operator 100 also includes a third rotating wheel 8 and a fourth rotating wheel 9; the third rotating wheel 8 is disposed on the second rotating shaft 3 at one end away from the first rotating wheel 4; the second rotating shaft 3 is an axially hollow structure, and a central shaft 7 is rotatably sleeved inside the second rotating shaft 3, one end of the central shaft 7 is fixedly connected to the second rotating wheel 5, and the other end is fixedly connected to the fourth rotating wheel 9.

[0072] The first rotating wheel 4 and the second rotating wheel 5 are located at one end of the fixed cylinder 1, and the third rotating wheel 8 and the fourth rotating wheel 9 are located at the other end of the fixed cylinder 1. In this way, the symmetry of the two ends of the two-stage adjustment operator 100 can be increased, so that both the left and right hands can perform adjustment operations.

[0073] The third rotating wheel 8 is fixedly connected to the second rotating shaft 3. Therefore, when the third rotating wheel 8 is rotated, the second rotating shaft 3, the first rotating wheel 4, and the first rotating shaft 2 rotate synchronously. The first rotating shaft 2 outputs rotational speed to achieve coarse adjustment. In addition, the fourth rotating wheel 9 is fixedly connected to the second rotating wheel 5 through the central shaft 7. When the fourth rotating wheel 9 is rotated, the second rotating wheel 5 will rotate, and drive the first rotating shaft 2 to rotate through the gear set 41 to achieve fine adjustment.

[0074] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0075] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
