Technical Field

The utility model belongs to the technical field of optics, a adjustment mechanism of optical component position in the optical machine system is related to. And more particularly to an adjustment mechanism that utilizes a thin plate to eliminate motion errors in non-adjustment directions.

Background

In opto-mechanical systems, the position of the optical components needs to be adjusted, which often has high accuracy requirements. Due to assembly tolerances between the components of the opto-mechanical system, undesired movements in the non-adjustment direction can occur during adjustment. For example, the arc swing table requires the swing between two components, but the two components are subject to the dislocation and the twist due to the assembly error of the rotating shaft. In many cases, the error caused by such non-adjusted orientation is not negligible and must be eliminated. The current method for eliminating the error is not to improve the assembly precision or add other high-precision structures. Both of these methods have high technical requirements and also result in high economic costs. To prior art's defect, the utility model provides a simple structure, low-cost utilizes the thin slice to realize the adjustment mechanism that the motion was kept apart.

Disclosure of Invention

Mechanically, the sheet material is easily bent in the thickness direction, and is resistant to large moment in the width and length directions, and is not easily deformed. The utility model discloses utilize this mechanical characteristic, utilize the deformation adaptation optical component's of thin slice thickness direction regulation direction, utilize width and length direction's non-deformable to keep apart the motion of non-regulation direction simultaneously. Therefore, the sheet material used in the present invention is not required to be excessively soft and have a certain rigidity, and is not easily brittle and flexible, and is limited by the deformation dimension of the material, and the adjusting mechanism is particularly suitable for small-amplitude adjustment, and the specific technical content is as follows:

the adjusting mechanism of the present invention comprises a base part as a position reference and an adjusting part for supporting the optical component and adjusting the position. Of course, the division of the two parts is only relative, so the description of the two parts in the present invention can be completely interchanged. The opposite ends of the thin sheet are respectively fixed with the base part and the adjusting part, the bending deformation of the thin sheet in the thickness direction adapts to the movement of the adjusting part in the adjusting direction, and the lateral movement and deflection of the adjusting part are limited in the width direction.

According to the structure of the base part and the adjusting part and the difference of the relative movement, the adjusting mechanism of the utility model also has different structures. The structure specifically has the following three structures:

I. adjusting mechanism of arc swing table structure

The existing arc swing table comprises a base part and an adjusting part which are connected through a side shaft to form an arc swing table structure. The adjusting part can make arc swinging movement relative to the base part through the adjusting part, and the included angle between the adjusting part and the base part can be adjusted. Due to tolerances in the shaft connection, such as axial and radial assembly play, horizontal movements and oscillations between the base part and the adjusting part occur. The utility model discloses in, with the both ends that the thin slice is relative with the direction that is on a parallel with the oscillating axle, it is fixed with base portion and regulating part respectively, fixed mode can adopt any mechanical fastening mode. The thin sheet can be arranged at one end close to the swinging shaft, can also be arranged at one end far away from the swinging shaft, and can also be respectively arranged at two ends of the thin sheet; the distance between the distal base portion and the adjustment portion will vary during adjustment, and the tabs at that end need to be pre-bent to accommodate this variation in distance. The bending deformation in the thickness direction of the sheet can adapt to the arc pendulum motion of the adjusting mechanism; meanwhile, since the sheet is not easily deformed in the sheet width direction (i.e., in the direction parallel to the swing axis of the arc table), the horizontal movement and swing of the regulating portion with respect to the fixing portion are restricted and isolated.

Further, the fixing position of the sheet may be on the upper and lower surfaces of the outer side of the arc swing table, or on the upper and lower surfaces opposite to the inner side, or on the end surface parallel to the swing shaft, or one end may be fixed on the outer plane or end surface of the base part, and the other end may be fixed on the end surface or outer plane of the adjusting part. An adjusting part can be arranged at one end far away from the swinging shaft, so that the thin sheet and the adjusting part need to be mutually avoided.

Preferably, the position of the swinging shaft can be provided with an actual mechanical shaft connecting fixing part and an actual mechanical shaft connecting adjusting part; instead of a mechanical shaft, the lamellae could be spring loaded up to the action of the pivot shaft. With this arrangement, if there is another tab at the distal end, the distal end tab is preferably of a flexible material to reduce the force applied to the adjustment portion in the vertical direction.

Further, the inner surface of the bent portion of the spring is in contact with an arc surface, which may be provided by a round bar or may be integral with the base portion. The arc surface provides a limiting support for the reed, and the stability of the adjusting mechanism is further improved.

And furthermore, a mounting frame is fixed at the end part of the base, 1 to 2 spring thimbles are mounted on the mounting frame and abut against the end surface of the adjusting part, thrust in the horizontal direction is applied, and horizontal deflection of the adjusting part is further overcome.

In another preferred scheme, the base part, the adjusting part and the spring plate are of an integral structure, namely, three parts are integrally shaped like Contraband, and transverse thin plates are processed at the upper and lower connecting parts to serve as the spring plate. The part as the reed can elastically deform along with the swing of the adjusting part and can restrict the movement in other directions.

Another arc swing table called a micro two-dimensional angle adjusting frame is generally used as a lens support and a filter support, a ball is supported at one angle between a base part and an adjusting part, two adjusting parts are respectively arranged in two mutually perpendicular directions through the ball, and arc swing adjustment can be carried out on the adjusting part around the ball in the two mutually perpendicular directions. It can also be said that the structure has two mutually perpendicular axes of oscillation. The arc-shaped swing platform can be respectively provided with thin sheets parallel to the two swing axes. The sheet is pre-bent to accommodate the change in distance between the base portion and the adjustment portion that occurs when swinging in the other direction. When the sheet swings in one direction, the sheet in the direction perpendicular to the sheet will generate a slight distortion. But because the adjustment of the product is micro-adjustment, the distortion in the other direction can be ignored. In each swinging direction, as with the arc swinging table swinging in one dimension, the sheet can be arranged at one end close to the swinging axis, can also be arranged at one end far away from the swinging axis, and can also be respectively provided with one sheet at each of the two ends; the positions of the two ends of the sheet fixed with the arc swing table can be the upper and lower surfaces of the outer side of the arc swing table, the upper and lower surfaces opposite to the inner side, the end surface parallel to the swing shaft, the outer plane or the end surface of the base part fixed with one end, and the end surface or the outer plane of the adjusting part fixed with the other end. An adjusting part can be arranged at one end far away from the swinging shaft, so that the thin sheet and the adjusting part need to be mutually avoided.

II. Adjusting mechanism of horizontal moving structure

In the conventional horizontally moving adjusting mechanism, a horizontal guide structure is arranged between a base part and an adjusting part, and the base part and the adjusting part can horizontally move along a linear direction. Also, due to tolerances between the connecting members, a shift or yaw may occur during the movement, resulting in a lateral shift or yaw in addition to a linear horizontal shift from the initial position.

The utility model discloses an adjustment mechanism of horizontal migration structure, with the orientation of thin slice with perpendicular to adjustment portion translation, fixed part and adjustment portion are fixed respectively at crooked back both ends. When the adjusting part moves horizontally relative to the fixed part, the bending part of the sheet changes to adapt to the horizontal displacement, but the transverse displacement is limited.

Further, the fixing position of the sheet may be on the upper and lower surfaces of the outer sides of the fixing portion and the regulating portion, or may be on the end surface.

Further, a thin plate may be fixed to each of both ends in the moving direction of the fixing portion and the adjusting portion, so that both ends are restricted from lateral displacement.

III, adjusting mechanism of turntable structure

In the conventional rotary disc type adjusting structure, a base disc serving as a base part and a rotary disc serving as an adjusting part are connected by a vertical shaft, one of the vertical shaft and the rotary disc is fixed with the shaft, and the other vertical shaft and the rotary disc rotate around the shaft in a rotary disc type. Due to the fit tolerance of the shaft connection, wobbling can occur during the rotation process.

The utility model discloses an adjustment mechanism of carousel structure sets up a set of radial distribution and rotatory face vertically thin slice, and the thin slice adopts the reed, and its inner is directly or indirectly fixed with fixed part or regulating part, and the outer end is directly or indirectly fixed with regulating part or fixed part. The fixed reed has pre-bending degree. Therefore, the movable reed is driven to synchronously generate elastic deformation when the rotary disc rotates, the reed is not easy to deform in the vertical direction, and the rotary disc is controlled not to shake.

Preferably, the lower part of the turntable is provided with a cavity, a rotating shaft is fixed on the chassis and is accommodated in the cavity, a group of reeds which are distributed in the radial direction and are vertical to the rotating surface are fixed on the near end of each reed and the rotating shaft, and the far end of each reed is fixed on the side wall of the cavity. The chassis and the turntable may be interchangeable. When the rotary table is rotated, the reed is driven to deform, the rotation of the rotary table cannot be limited by the reed, and meanwhile, the vertically arranged reed is not easy to deform in the vertical direction, so that the shaking of the rotary table can be limited.

The scheme is further that a circular truncated cone is arranged on the chassis, and the rotating shaft is arranged in the center of the upper part of the circular truncated cone; the cavity of the turntable is cylindrical and is coaxial with the circular truncated cone and is larger than the diameter of the circular truncated cone; a bearing is arranged between the circular truncated cone and the side wall of the containing cavity, an inner ring of the bearing is fixed with the side wall of the circular truncated cone, and an outer ring of the bearing is fixed with the side wall of the containing cavity. And the upper part of the cavity is provided with a group of reeds which are radially distributed and vertical to the rotating surface, the near ends of the reeds are fixed with the rotating shaft, and the far ends of the reeds are fixed with the side wall of the cavity. The chassis and the turntable may be interchangeable. In the former solution, if the reeds are not uniformly deformed during the rotation of the turntable, the turntable is displaced horizontally. The bearing is added between the chassis and the turntable, so that the horizontal displacement of the turntable is limited by the bearing.

Preferably, the reed structure is made into a reed spoke wheel which is formed into a group of reeds which are distributed in the radial direction and are vertical to the rotating surface, the near ends of the reeds are fixed with the inner ring of the spoke wheel, and the far ends of the reeds are fixed with the outer ring of the spoke wheel.

Detailed Description

I. Adjusting mechanism of arc swing table structure

Examples I-1

As shown in fig. 1. The adjusting mechanism of the arc swing table structure of the embodiment comprises a base part A11 and an adjusting part A12 connected with the base part A11 through a swing shaft 13, an adjusting piece A15 and a tension spring 16 are arranged between the base part A11 and the free end of the adjusting part, the adjusting piece A15 adjusts the relative swing of the adjusting piece A, and the tension spring 16 keeps the stress of the adjusting piece A in the closing direction; one end of the swing shaft 13 is arranged outside the arc swing table, the sheet 14 is parallel to the swing shaft 13, and two ends of the sheet are fixedly connected with the end surface of the base part A11 and the upper surface of the adjusting part A12 respectively.

When the adjusting part a12 swings around the swing shaft 13, the sheet 14 changes its curvature without affecting or restricting the swing, and the sheet 14 is not easily deformed in its width direction, so that the horizontal dislocation and twisting of the adjusting part a12 with respect to the base part a11 due to the assembly tolerance of the swing shaft 13 can be restricted. Motion isolation in the non-adjusted direction is achieved.

Examples I to 2

As shown in fig. 2. This embodiment is based on embodiment I-1 and adds a tab 14' at the distal end parallel to axis 13, which further improves the accuracy of the adjustment. The individual thin pieces 14 may be twisted to become unable to completely eliminate the horizontal swing error of the regulating portion 11; the additional sheet 14' cooperates with the sheet 14 to constrain the horizontal oscillation of the adjustment part 11 at both ends so that the horizontal oscillation error is negligible. During adjustment, the distance between the distal base portion A11 and the adjustment portion A12 changes, and the tab 14' at that end needs to be pre-bent to accommodate this change in distance.

In fig. 2 the tab 14' is shown resting on the end faces of the base portion a11 and the adjustment portion a 12. In fact, the fixing positions can also be the inner side surface and the outer side surface of the base portion a11 and the adjusting portion a12, referring to the fixing position of the sheet 14 in this figure and fig. 3. When the adjusting piece A15 and the tension spring 16 are retracted, the adjusting piece A15 and the tension spring 16 are mutually avoided.

In the following examples I-3 and I-4, it is also possible to add, as in the present example, a lamella 14' at the distal end parallel to the axis 13. The following description is not repeated.

Examples I to 3

As shown in fig. 3. The present embodiment is different from embodiment i-1 only in that the sheet 14 of the present embodiment is placed inside the arc swinging table and fixedly connected to the inner surfaces of the base portion a11 and the regulating portion a12, respectively, in parallel to the swinging axis. The rest were the same as in example I-1.

Examples I to 4

As shown in fig. 4. The present embodiment is different from embodiment i-1 only in that the sheet 14 of the present embodiment is placed on the shaft-side end surface of the arc swing table and fixedly connected to the end surfaces of the base portion a11 and the regulating portion a12, respectively, in parallel with the swing shaft 13. The rest were the same as in example I-1.

Examples I-5 to I-8

As shown in fig. 5 to 8, the embodiments of the present invention i-5 to i-8 are schematically illustrated. Corresponding to examples I-1 to I-4, respectively, except that the oscillating shaft 13 was eliminated and the leaf spring A141 was used as the proximal end tab. The rigidity of the reed is used to replace the swing shaft to support the adjusting part. Namely the reed supports the regulating part, and can not bounce up and down under normal load; when the adjusting member adjusts the swing angle, the bending degree of the spring piece A141 is changed, the swing is not influenced or limited, and the spring piece A141 is not easy to deform in the width direction, so that the horizontal dislocation and twisting of the adjusting part A12 relative to the base part A11 can be limited. Motion isolation in the non-adjusted direction is achieved.

Example I-6 shown in FIG. 6, as was example I-2 shown in FIG. 2. A tab 14' is added at the distal end of leaf a141 parallel to replacement shaft 13. The flap 14' is preferably of a flexible material to reduce the force applied to the adjustment portion in the vertical direction.

Examples I to 9

As shown in fig. 9. In this embodiment, the spring a141 is fixed to the end surface of the base a11 and the lower surface of the adjustment part a12, respectively, and the inner surface of the bending part of the spring is in contact with an arc surface, which may be provided by the round rod 17 or integrated with the base part, and if the round rod is adopted, the spring a141 can be adjusted by round rods with different diameters. The arc surface provides a limiting support for the reed A141, and the stability of the adjusting mechanism is further improved. Other parts of this embodiment are the same as the other embodiments and a sheet 14' may also be added.

Examples I to 10

As shown in fig. 10. In the present embodiment, on the basis of the previous embodiment, the mounting frame 18 is fixed at the end of the base portion a11, and 1 to 2 pogo pins 19 are mounted on the mounting frame 18 to push against the end surface of the adjusting portion, so as to apply a horizontal thrust, and further overcome the horizontal deflection of the adjusting portion.

Examples I to 11

As shown in fig. 11. The base portion a11, the adjusting portion a12 and the spring a141 of the present embodiment are of an integral structure, that is, three portions are integrally formed in a shape of "Contraband", and a transverse sheet is formed at the upper and lower connecting portions as the spring a 141. The portion serving as the reed a141 is elastically deformed in accordance with the swing of the regulation portion a12, and can restrict the movement in the other direction.

Examples I to 12

As in fig. 12. An arc swinging table called a miniature two-dimensional angle adjusting frame is generally used as a lens support and a filter support, a ball 13 ' is supported at one corner between a base part A11 and an adjusting part A12, a set of adjusting piece A15 and a tension spring 16 are respectively arranged in two mutually perpendicular directions passing through the ball 13 ', and arc swinging adjustment can be carried out on the adjusting part A12 around the ball 13 ' in the two mutually perpendicular directions. It can also be said that the structure has two mutually perpendicular axes of oscillation. One lamella 14 is arranged parallel to each of the two pivot axes. To accommodate the change in distance between the base portion A11 and the adjustment portion A12 that occurs when swinging in the other direction, the flap 14 needs to be pre-bent. In this configuration, the sheet 14 in the direction perpendicular to the direction of oscillation in one direction is slightly distorted. But because the adjustment of the product is micro-adjustment, the distortion in the other direction can be ignored.

In each swing direction, like the arc swing table of the one-dimensional swing, the sheet 14 may be installed at one end close to the swing axis, or at one end far away from the swing axis, or at both ends; the positions of the two ends of the sheet fixed with the arc swing table can be the upper and lower surfaces of the outer side of the arc swing table, the upper and lower surfaces opposite to the inner side, the end surface parallel to the swing shaft, the outer plane or the end surface of the base part fixed with one end, and the end surface or the outer plane of the adjusting part fixed with the other end. An adjusting part can be arranged at one end far away from the swinging shaft, so that the thin sheet and the adjusting part need to be mutually avoided.

II. Embodiments of adjusting mechanisms for horizontal moving structures

Example II-1

As shown in fig. 13. The adjusting mechanism of the horizontal moving structure comprises a base part B21 and an adjusting part B12, wherein an adjusting piece B23 at one end pushes and pulls the adjusting part B12 to horizontally move on the base part B21 along the direction of a double arrow in the figure. The middle portion of the distal end sheet 24 is pre-bent, and both ends are fixed to the lower surface of the base portion B21 and the upper surface (i.e., outer upper and lower surfaces) of the regulating portion B12, respectively, perpendicularly to the moving direction at the distal end of the regulating member B23. When the adjustment portion B12 is moved horizontally relative to the fixed portion 11, the bending portion of the sheet 24 is varied to accommodate the horizontal displacement, but lateral deflection is restricted.

Example II-2

As in fig. 14. The present embodiment is different from the previous embodiment in that the middle pre-bent thin sheet 24 has both ends fixed to the distal end surfaces of the base portion B21 and the regulating portion B12, respectively. The other parts are the same as the previous embodiment.

Example II to 3

As in fig. 15. In addition to the distal flap 24, a proximal flap 25 is also secured to one end of the adjustment member. Thus, the endless web limits the distal end to lateral runout, while the proximal web 25 further limits the lateral runout of one end of the adjuster. In FIG. 15, the fixing manner of the sheet is shown as that of example II-1, that is, the fixing to the outer upper and lower surfaces. Of course, the fixing method of embodiment II-2, i.e., fixing on the upper and lower end surfaces, can also be adopted.
