Description

Technical Field

[0001] This utility model relates to a cylindrical mirror adjustment mechanism, belonging to the field of optical device technology. Background Technology

[0002] In the field of optical applications, cylindrical mirror adjustment mechanisms play a crucial role in achieving precise spot control and optimizing optical performance.

[0003] Current cylindrical mirror adjustment devices are mainly multi-axis manual adjustment mechanisms. These traditional mechanisms use manual knobs or handwheels to drive precision lead screws and guide rail systems to adjust the position of the cylindrical mirror in three-dimensional space. However, this structure not only suffers from bulky size and inefficient operation, but also relies too heavily on manual adjustment, making it unable to meet the dynamic calibration requirements of complex optical paths, especially for multi-cylindrical mirror combination systems.

[0004] Furthermore, multi-cylindrical mirror systems typically include at least two cylindrical mirrors in the vertical direction, which have two major alignment requirements: optical axis coaxiality and mirror surface parallelism. However, existing technologies not only lack adjustment mechanisms for multi-cylindrical mirrors, but also fail to reduce the pressure of manual adjustment, which makes it difficult to align the cylindrical mirrors.

[0005] Therefore, there is an urgent need to find an adjustment mechanism that can adjust at least two cylindrical mirrors and can solve the problem of cumbersome manual operation to some extent. Utility Model Content

[0006] To solve the above problems, this utility model provides a cylindrical mirror adjustment mechanism, comprising:

[0007] The mounting base has a vertically oriented track;

[0008] The fixed adjustment module includes a first adjustment seat fixedly connected to the mounting base and a first clamp carried by the first adjustment seat; the first adjustment seat includes a U-shaped frame and adjustment mechanisms installed on both sides of the U-shaped frame; when the first clamp is engaged with the U-shaped frame, the engaging part can abut against the adjustment mechanism;

[0009] A movable adjustment module is located vertically in the direction of the fixed adjustment module. The movable adjustment module includes a second adjustment seat movably connected to the track and a second clamp carried by the second adjustment seat. The second adjustment seat has the same structure as the first adjustment seat, and the second clamp has the same structure as the first clamp.

[0010] A drive component is connected to the motion adjustment module, and the drive component is capable of driving the motion adjustment module to move along the track.

[0011] Furthermore, the spiral frame includes an inner ring structure and an outer ring structure, with an annular gap space between the inner ring structure and the outer ring structure, and at least a portion of the adjustment mechanism is placed within the annular gap space.

[0012] Furthermore, the adjustment mechanism includes:

[0013] A left adjustment mechanism is installed on the left side of the annular gap space. The left adjustment mechanism includes an adjustment shaft that cooperates with the outer ring structure. At least a portion of the adjustment shaft passes through the annular gap space and a tapered head is provided at one end of the shaft that passes through the annular gap space. The adjustment shaft is arranged along the left side of the outer ring structure. A steel ball is fitted between the tapered head and the inner ring structure. At least a portion of the steel ball is exposed on the inner and outer sides of the annular gap space.

[0014] A right adjustment mechanism is installed on the right side of the annular gap space. The right adjustment mechanism includes a spring plunger fixed to the right side of the annular gap space, and at least a portion of the spring plunger is exposed on the inside and outside of the annular gap space.

[0015] Furthermore, an adjustment knob is provided at the end of the adjustment shaft that does not enter the annular gap space. By rotating the adjustment knob, the displacement of the conical head along the shaft and the left side of the outer ring structure can be controlled. When the conical head moves toward the insertion direction, it can push the steel ball to move toward the inner and outer sides of the annular gap space.

[0016] Furthermore, a kit capable of accommodating the conical head and steel ball is provided on the left side of the annular gap space.

[0017] Furthermore, both the bottom of the first clamp and the bottom of the second clamp are provided with cylindrical members, and the inner ring structure is provided with a circular hole that mates with the cylindrical member.

[0018] Furthermore, both the first clamp and the second clamp are groove-shaped structures.

[0019] Furthermore, an anti-slip pad is provided on the inner side of the groove structure.

[0020] Furthermore, the movable adjustment module is located below the fixed adjustment module.

[0021] Furthermore, the drive assembly includes a motor and a linear module connected to the motion adjustment module.

[0022] The beneficial effects of this utility model are:

[0023] This invention features a fixed adjustment module and a movable adjustment module that respectively clamp two cylindrical mirrors. A drive assembly controls the movable adjustment module to adjust the distance between the two cylindrical mirrors. Both the fixed and movable adjustment modules are equipped with clamps and adjustment seats. The adjustment seats utilize an adjustment shaft, steel balls, and spring plungers to achieve lateral adjustment of the cylindrical mirrors on a flat surface for alignment. This invention not only overcomes the shortcomings of existing technologies that lack two cylindrical mirror adjustment mechanisms but also achieves a semi-automatic adjustment mode to some extent through the cooperation of the adjustment shaft and spring plunger, reducing the burden of manual adjustment. Furthermore, the modular design of this invention results in a compact device structure, reducing its size, and it can be used independently on an optical platform or installed in other optical equipment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Example 1

[0032] This utility model provides a cylindrical mirror adjustment mechanism, such as Figure 1 As shown, it includes a mounting base 1, a fixed adjustment module 2, a movable adjustment module 3, and a drive assembly 4, wherein:

[0033] Mounting base 1 is a vertical plate with a vertically oriented track, which can be connected to other optical devices for combined use;

[0034] The fixed adjustment module 2 includes a first adjustment seat fixedly connected to the mounting base 1 and a first clamp 22 supported by the first adjustment seat 21. The first adjustment seat 21 is fixedly installed on the top of the track of the mounting base 1. The first adjustment seat 21 includes a U-shaped frame and adjustment mechanisms installed on both sides of the U-shaped frame. When the first clamp 22 is engaged with the U-shaped frame, the engaging part can abut against the adjustment mechanism. The U-shaped frame includes an inner ring structure and an outer ring structure, with an annular gap space between the inner ring structure and the outer ring structure. At least one part of the adjustment mechanism is placed within the annular gap space, and the other part is exposed outside the annular gap space. It should be understood that the outer ring structure and the inner ring structure of the U-shaped frame refer to the outer ring edge layer and the inner ring edge layer, respectively, and the space between the outer ring edge layer and the inner ring edge layer is the annular gap space.

[0035] The movable adjustment module 3 is located vertically below the fixed adjustment module 2. The movable adjustment module 3 includes a second adjustment seat movably connected to the track and a second clamp carried by the second adjustment seat. The second adjustment seat has the same structure as the first adjustment seat, and the second clamp has the same structure as the first clamp. Since the second adjustment seat is installed on the track, the second adjustment seat can move vertically along the track, thereby changing the distance between it and the first adjustment seat 21.

[0036] The drive component 4 is connected to the motion adjustment module 3. The drive component 4 includes a motor and a linear module connected to the motion adjustment module 3. The linear module can drive the motion adjustment module 3 to move along the track, thereby realizing automated control of the distance between the two cylindrical mirrors 5.

[0037] Furthermore, the adjustment mechanism includes:

[0038] A left adjustment mechanism is installed on the left side of the annular gap space. The left adjustment mechanism includes an adjustment shaft 211 that is fitted to the outer ring structure. At least a portion of the adjustment shaft 211 passes through the annular gap space and a tapered head 212 is provided at one end of the shaft that passes through the annular gap space. The other portion remains outside the annular gap space and is exposed on the surface of the outer ring structure. The portion of the adjustment shaft 211 that passes through the annular gap space is arranged along the left side of the outer ring structure.

[0039] A steel ball 213 is fitted between the conical head 212 and the inner ring structure. The portion of the steel ball 213 that engages with the conical head 212 is concealed within the annular gap space, while the other portion is exposed on the inner and outer sides of the annular gap space and on the surface of the inner ring structure. Due to the inclined surface of the steel ball 213 engaging with the conical head 212, when the conical head 212 moves in the insertion direction, the inclined surface of the conical head 212 compresses and pushes the steel ball 213 towards the inner and outer sides of the annular gap space, thus exposing a larger portion of the steel ball 213 on the surface of the inner ring structure.

[0040] The right adjustment mechanism is installed on the right side of the annular gap space. The right adjustment mechanism includes two spring plungers 215 fixed on the right side of the annular gap space. Part of the spring plungers 215 is exposed on the outside of the inner side of the annular gap space, that is, exposed on the surface of the inner ring structure, while the other part is hidden in the annular gap space. It should be understood that when compressed, the spring plungers 215 have elastic potential energy.

[0041] Furthermore, an adjustment knob 214 is provided at the end of the adjustment shaft 211 that does not enter the annular gap space. By rotating the adjustment knob 214, the displacement of the conical head 212 along the left side of the outer ring structure can be controlled. When the conical head 212 moves toward the insertion direction, it can push the steel ball 213 to move toward the inner and outer sides of the annular gap space.

[0042] Furthermore, a kit capable of accommodating the conical head 212 and the steel ball 213 is provided on the left side of the annular gap space. The kit can be provided with a conical cavity inside, which can both protect the conical head 212 and provide guidance for the movement of the conical head 212.

[0043] Furthermore, both the first clamp 22 and the second clamp are groove-shaped structures, and the cylindrical mirror 5 is assembled in the groove-shaped structure. Preferably, an anti-slip pad is provided on the inner side of the groove-shaped structure. The bottom of both the first clamp 22 and the second clamp are provided with cylindrical members, and the inner ring structure is provided with a circular hole that matches the cylindrical member. After such matching, the first clamp 22 and the second clamp can be rotated in a plane.

[0044] When it is necessary to use this utility model to adjust the coaxiality of the optical axes of two cylindrical mirrors, the two cylindrical mirrors 5 are respectively installed on the first clamp 22 of the fixed adjustment module 2 and the second clamp of the movable adjustment module 3, and the steel ball 213 and the spring plunger 215 respectively abut against the two sides of the cylindrical mirror 5. On the one hand, the distance between the lower and upper cylindrical mirrors can be changed by controlling the movement of the second clamp through the drive component 4, thereby changing the shape and size of the light spot; on the other hand, the steel ball 213 can be pushed into the annular gap space by rotating the adjustment shaft 211 inward through the adjustment knob 214, so that the steel ball 213 can push the cylindrical mirror 5 to move horizontally to the right; further, by rotating the adjustment shaft 211 outward through the adjustment knob 214 to release the pressure on one side of the steel ball 213, since the spring plunger 215 on the right side is compressed and generates elastic potential energy when the steel ball 213 pushes the cylindrical mirror 5 to the right, the spring plunger 215 on the right side recovers when the pressure on the steel ball 213 is released, and under the elastic action, the cylindrical mirror 5 is pushed horizontally to the left. A part of the steel ball 213 is pushed back to the initial position of the annular gap space and abuts against the conical head 212, thereby realizing the left and right pushing of the cylindrical mirror 5 in the horizontal direction.

[0045] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
