Example one

Referring to fig. 1 to 5, a first embodiment of the present application provides an adjusting device, which can be used to adjust a mounting position of an optical element in multiple dimensions, such as translation, rotation, and pitch, so as to finally position and mount the optical element in an optical path of an optical system; the adjusting device includes a carrier 10, a base member 20, a first fixing member 30, a first adjusting member 40, a second fixing member 50, and other components as required.

The adjusting device is mainly described below with the reflecting mirror a as an optical element to be adjusted, but it should be noted that the reflecting mirror a is only one specific application or object of the adjusting device, and the adjusting device can also be used for position adjustment and installation fixing of a filter, a spectroscope or other types of optical elements.

Referring to fig. 1 to 5, the supporting member 10 has a supporting portion 10a and a mounting portion 10b; the support portion 10a is mounted on the base member 20 so as to be rotatable with respect to the base member 20, and the support portion 10a is stacked on the base member 20 in the vertical direction and rotatable with respect to the base member 20 in the vertical direction, for example. For the sake of distinction and description, the rotation axis of the support portion 10a is defined as a first axis L1. A guide structure is provided between the supporting portion 10a and the base member 20, and the guide structure includes a first guide structure provided on the base member 20 and a second guide structure provided on the supporting portion 10a, and the first guide structure and the second guide structure are movably connected (for example, in a clearance fit) to play a role of guiding or guiding when the supporting portion 10a rotates around the first axis L1 relative to the base member 20, so as to prevent the supporting portion 10a and the base member 20 from generating relative linear translational motion, and ensure that the supporting portion 10a has only one rotational degree of freedom relative to the base member 11.

The mounting portion 10b is mainly used as a mounting carrier of the mirror a, that is: the mirror A is fixedly mounted on the mounting portion 10 b. The mounting portion 10b is arranged on a side of the supporting portion 10a facing or facing away from the base member 20 along the first axis L1, for example, the mounting portion 10b is arranged on a lower side of the base member 20 and distributed throughout the base member 20; meanwhile, the mounting portion 10b is movably connected to the supporting portion 10a through a hinge structure, a flexible structure, and the like, so that the mounting portion 10b has a capability of rotating relative to the supporting portion 10 a. For the sake of distinction and description, the rotational axis of the mounting portion 10b is defined as a second axis L2; in practical applications, the first axis L1 and the second axis L2 are perpendicular to each other.

Referring to fig. 1 to 4, the first fixing member 30 is mainly used to fix the supporting portion 10a on the base member 20 to fix the relative position therebetween; specifically, after the supporting portion 10a (or the carrier 12) rotates around the first axis L1 by a preset angle relative to the base member 20, the supporting portion 10a and the base member 20 may be connected and fixed by the first fixing member 30, so as to ensure that the relative position of the supporting portion 10a and the base member 20 does not change.

Referring to fig. 1, 2, 4 and 5, a first adjusting member 40 is disposed on the supporting portion 10a and connected (e.g., in contact with, etc.) with the mounting portion 10b; the first adjusting element 40 is mainly used for driving the mounting portion 10b to drive the reflector a to rotate around the second axis L2 relative to the supporting portion 10a in a pushing and pulling manner, so as to adjust the relative position between the mounting portion 10b and the supporting portion 10a; meanwhile, the structural relationship established between the mounting portion 10b and the support portion 12 by the first adjustment member 40 enables the mounting portion 10b (together with the mirror a) to stay at a preset angular position relative to the support portion 12 to fix the relative position between the mounting portion 10b and the support portion 10 a.

Referring to fig. 1 to 4, the base member 20 is mainly used as a mounting carrier or a connection carrier between the device body and the optical carrier B; the optical carrier B is understood to be a structural member capable of assembling various and/or multiple optical elements in an optical system or an optical apparatus, such as a housing, a bracket, and the like of the optical apparatus. The base member 20 is mounted on the optical carrier B in a linearly translatable manner with respect to the optical carrier B; for ease of distinction and description, the movement trajectory (or path, direction, etc.) of the base member 20 is defined as a third axis L3; in practical applications, the third axis L3 is perpendicular to the first axis L1, and the third axis L3 and the second axis L2 may be parallel to each other or spatially cross each other.

Referring to fig. 1 to 4, the second fixing element 50 is mainly used for connecting and fixing the base element 20 (or the entire device together with the reflecting mirror a) and the optical carrier B, and specifically, after the base element 20 moves to a predetermined position along the third axis L3 relative to the optical carrier B, the base element 20 and the optical carrier B can be connected and fixed by the second fixing element 50 to ensure that the relative positions of the base element 20 and the optical carrier B are not changed.

When the reflector A is assembled, the reflector A can be fixedly arranged on the installation part 10B in advance, the bearing member 10 and the base member 20 are subjected to preliminary assembly by the aid of the first fixing member 30 (namely, the first fixing member 30 does not completely fix the supporting part 10a and the base member 20), and the whole assembling device and the optical carrier B are subjected to preliminary assembly by the aid of the second fixing member 50 (namely, the base member 20 and the optical carrier B are not completely fixed by the second fixing member 50); and then, finely adjusting the angle, the direction and the like of the reflector A according to the relative position between the reflector A and the preset light path.

For example, the base member 20 (or the entire device) may be first manipulated to translate along the third axis L3 on the optical carrier B, and after the base member 20 reaches the predetermined position, the base member 20 may be fixed on the optical carrier B by the second fixing member 50, so as to complete the translational adjustment of the mirror a. Then, the supporting portion 10a (or the bearing member 10) is manipulated to rotate on the base member 20 about the first axis L1, and after the supporting portion 10a reaches the predetermined angular position, the supporting portion 10a is fixed to the base member 20 by the first fixing member 30, thereby completing the rotational adjustment of the mirror a. Finally, the first adjusting member 40 is manipulated to drive the mounting portion 10b to drive the mirror a to rotate around the second axis L2 by a preset angle relative to the supporting portion 10a, so that the mounting portion 10b (together with the mirror a) is kept at the current position, thereby completing the pitching adjustment of the mirror a.

Of course, in practice, the order of the translational adjustment, the rotational adjustment and the pitching adjustment may be adaptively adjusted, or only one or both of the adjustment operations may be performed according to the specific position of the reflecting mirror a in the space.

Based on this, by using the structural characteristics that the base member 20 can translate relative to the optical carrier B, the support portion 10a can rotate relative to the base member 20, and the mounting portion 10B can rotate relative to the support portion 10B, the mirror a can be finely adjusted in multiple dimensions such as translation, rotation, and pitch, so that mounting errors of the mirror a (for example, errors caused by processing errors between the first fixing member 30 and the base member 20, and between the second fixing member 50 and the optical carrier B, and form and position errors) can be eliminated, and the mounting accuracy of the mirror a is improved.

Referring to fig. 1, 2 and 4, in one embodiment, the first guiding structure includes a plurality of first guiding columns 21, the first guiding columns 21 are protruded from a surface of the base 20 facing the supporting portion 10a, and the plurality of first guiding columns 21 are uniformly and alternately arranged around the first axis L1; suitably, the second guiding structure includes a plurality of first guiding slideways 11, the first guiding slideways 11 are arc-shaped through-hole structures disposed through the supporting portion 10a, and the plurality of first guiding slideways 11 are matched with the plurality of first guiding columns 21 in a one-to-one alignment manner. Specifically, the first guiding column 21 is inserted into the corresponding first guiding slideway 11 to establish a clearance fit connection relationship therebetween.

When the supporting part 10a rotates around the first axis L1 relative to the base member 20, the supporting part 10a is guided to rotate directionally by the cooperation of the first guide column 21 and the first guide slideway 11; meanwhile, by utilizing the characteristics that the plurality of first guide columns 21 and the plurality of first guide slideways 11 are uniformly distributed around the first axis L1 and the matching relationship between the plurality of first guide columns and the plurality of first guide slideways, the support part 10a can be effectively prevented from moving in the adjusting movement process, so that the support part 10a can be ensured to have only one rotational degree of freedom relative to the base part 20, and conditions are created for improving the adjusting precision of the relative position between the support part 10a and the base part 20.

In other embodiments, the first guiding slideway 11 may also adopt an arc-shaped groove structure, and the first guiding cylinder 21 is inserted into the first guiding slideway 11 in a clearance fit manner. Or, the positions of the first guiding column 21 and the first guiding slideway 11 can be changed, that is: the first guide runner 11 is disposed on a surface of the base member 20 facing the support portion 10a, and the first guide cylinder 21 is disposed protruding from a surface of the support portion 10a facing the base member 20.

In one embodiment, referring to fig. 1, 2 and 4, the base member 20 is provided with a first locking structure, which includes a plurality of threaded holes 22 disposed on a surface of the base member 20 facing the supporting portion 10a, the plurality of threaded holes 22 being uniformly and spaced around the first axis L1; suitably, the supporting portion 10a is provided with a first matching structure, the first matching structure includes a plurality of matching bar holes 12 uniformly and alternately arranged around the first axis L1, and the matching bar holes 12 are arranged through the supporting portion 10a; the number of the first fixing members 30 is set to be plural, and a screw structure can be adopted; the plurality of first fixing pieces 30, the plurality of fitting bar holes 12 and the plurality of threaded holes 22 correspond one to one.

Specifically, when the relative position between the support portion 10a and the base member 20 is rotationally adjusted, the first fixing member 30 is inserted into the corresponding threaded hole 22 via the corresponding mating hole 12, but the support portion 10a and the base member 20 are not completely locked and fixed; in the process of rotating the supporting part 10a relative to the base member 20, on one hand, the supporting part 10a is guided to rotate directionally by the engagement of the first guide structure and the second guide structure, and on the other hand, the engagement strip hole 12 and the first fixing member 30 are in a clearance fit relationship, so that the supporting part 10a can be supported to rotate relative to the base member 20. After the supporting part 10a rotates a predetermined angle, the supporting part 10a and the base member 20 are locked and fixed by the screw connection relationship between the first fixing member 30 and the screw hole 22.

In other embodiments, the first locking structure (specifically, the threaded hole 22) and the first mating structure (specifically, the mating strip hole) may be omitted; correspondingly, the first fixing member 30 adopts a threaded sleeve or nut structure; at least a portion of the first guide cylinder 21 may be configured as a screw structure, and the first guide rail 11 may be configured as an arc-shaped through hole penetrating the support portion 10 a. In this way, after the supporting portion 10a rotates relative to the base member 20 by a predetermined angle, the supporting portion 10a and the base member 20 can be locked and fixed by using the threaded connection relationship between the first fixing member 30 and the first guide column 21, which is beneficial to simplifying the overall structure of the device.

In one embodiment, referring to fig. 5, the supporting member 10 further has a flexible joint 10c, and the mounting portion 10b is connected to the supporting portion 10a through the flexible joint 10 c; the flexible joint 10c may be integrally formed with the mounting portion 10b and the supporting portion 10a (i.e., the carrier 10 may be integrally formed based on material selection), and the size (e.g., thickness) of different portions of the carrier 10 may be selectively controlled, so that the flexible joint 10c is a weak portion between the mounting portion 10b and the supporting portion 10a; in this way, when the first adjusting member 40 rotates the mounting portion 10b relative to the supporting portion 10a, the flexible joint portion 10c is elastically or flexibly deformed about the second axis L2 by the bending moment, so that the relative position between the mounting portion 10b (or the mirror a) and the supporting portion 10a can be adjusted and fixed.

In other embodiments, the flexible joint 10c may be made of an elastic material or a flexible material and fixedly installed between the mounting portion 10b and the supporting portion 10a; so that a relatively movable connection relationship is established between the mounting portion 10b and the supporting portion 10a by the flexible joint portion 10 c.

In one embodiment, referring to fig. 5, the first adjusting member 40 is a substantially screw structure, which is disposed through the supporting portion 10a in a direction parallel to the first axis L1, and is screwed with the supporting portion 10a; correspondingly, the mounting portion 10b is provided with a mounting structure 13 and a connecting structure 14; the assembling structure 13 is mainly used for fixedly mounting the reflector A, and the structural form of the assembling structure can be matched with that of the reflector A; the connecting structure 14 is located between the mounting structure 13 and the flexible joint portion 10c, and the end of the first adjusting member 40 is connected (e.g., contact-connected, sliding-connected) with the connecting structure 14; in this way, the first adjusting member 40 can be driven to move in a direction parallel to the first axis L1 by rotating, and the connecting structure 14 can be pushed or pulled, while the mounting portion 10b (or the mirror a mounted on the mounting structure 13) can be rotated about the second axis L2 due to the flexible joint portion 10 c.

In a specific implementation, the number of the first adjusting members 40 may be two, and the two first adjusting members 40 are symmetrically arranged on both sides of the mounting portion 10b about the second axis L2; the connecting structure 14 is arranged to protrude from the corresponding surface of the mounting portion 10b; at this time, the two first adjusting members 40 can be used to cooperate with the corresponding connecting structures 14 to drive the mounting portion 10b to rotate around the second axis L2 in different directions, so as to achieve fine adjustment and fixing of the pitch angle of the reflector a.

In one embodiment, referring to fig. 4, the base member 20 is provided with an assembly window 20a, the assembly window 20a being disposed through the base member 20 along a first axis L1; suitably, a first guide structure, a first locking structure, etc. may be arranged at the periphery of the fitting window 20 a; the mounting window 20a is primarily used to provide structural access for the mounting portion 10B (along with the mirror a) to mount to the interior of the optical carrier B. The mounting portion 10b penetrates the base member 20 through the fitting window 20a and is located on the side of the base member 20 facing away from the support portion 11 in terms of the device as a whole; therefore, after the reflector A is arranged on the optical carrier B, relevant components and structures which play a role in adjusting and fixing in the adjusting device are exposed out of the optical carrier B, so that the reflector A is convenient to perform corresponding adjusting operation, and unnecessary interference of the adjusting device on an optical path can be reduced.

In one embodiment, referring to fig. 1 and fig. 2, the adjusting device further includes a second adjusting member 60, wherein the second adjusting member 60 is mainly used for driving the base member 20 to move on the optical carrier B along a third axis L3 to finely adjust the relative position between the base member 20 and the optical carrier B; the second adjusting members 60 can adopt a screw structure with reference to the first adjusting members 40, and in particular, two second adjusting members 60 can be provided, and two second adjusting members 60 are arranged on two sides of the base member 20 along the third axis L3; at the same time, the second adjuster 60 is screwed to the optical carrier B. The second adjusting member 60 can be urged to advance along the third axis L3 relative to the optical carrier B by rotating so as to push the base member 20 to move synchronously and in the same direction; so that the position of the base member 20 on the optical carrier B is finely adjusted accurately by the threaded connection of the second adjusting member 60 to the optical carrier B.

In one embodiment, referring to fig. 2 and 3, a guiding structure is disposed between the base member 20 and the optical carrier B, and the guiding structure includes a third guiding structure disposed on the base member 20 and a fourth guiding structure disposed on the optical carrier B; wherein the third guiding structure comprises a second guiding cylinder 23 protruding from a side of the base member 20 facing the optical carrier B; suitably, the fourth guiding structure comprises a second guiding track B1 extending along the third axis L3 or in a direction parallel to the third axis L3, the second guiding track B being a strip-shaped groove structure arranged on a side of the optical carrier B facing the base member 20.

When the base member 20 is assembled to the optical carrier B, the second guiding cylinder 23 is inserted into the second guiding slideway B, so as to form a clearance fit therebetween. When the base member 20 is driven to move by the second adjusting member 60, the base member 20 can be guided to perform a directional translational movement along the third axis L3 by the cooperation of the second guiding cylinder 23 and the second guiding slide B, so as to provide a guarantee for translational fine adjustment of the relative position between the base member 20 and the optical carrier B.

In other embodiments, the positions of the second guiding column 23 and the second guiding sliding way B1 can be exchanged, that is: the second guiding cylinder 23 is disposed on the optical carrier B, and the second guiding slideway B1 is disposed on the base member 20.

In one embodiment, referring to fig. 2 and 3, the base member 20 is further provided with a third locking structure, which includes a plurality of locking bar openings 24 extending along the third axis L3 or along a direction parallel to the third axis L3, and the locking bar openings 24 may be through hole structures provided through the base member 20 or notch structures provided at the edge of the outline of the base member 20; the second fixing member 50 can refer to the first fixing member 30 and adopt a screw structure, the number of the second fixing members 50 is multiple, and the multiple second fixing members 50 are matched with the multiple locking strip openings 24 one by one (i.e. the second fixing members 50 are arranged through the corresponding locking strip openings 24 to form a clearance fit relation therebetween); suitably, a screw hole structure is provided on the optical carrier B.

After the base member 20 is adjusted to the predetermined position of the optical carrier B, the second fixing member 50 can be screwed into the screw hole structure of the optical carrier B by screwing, so as to finally lock and fix the base member 20 on the optical carrier B. Because the second fixing member 50 is in clearance fit with the locking bar openings 24, the base member 20 can be adjusted in translation.
