Description

Technical Field

[0001] This invention relates to the field of optomechanical structure technology, and in particular to an online two-dimensional rotation adjustment device for a mirror. Background Technology

[0002] In optical systems, especially coaxial systems, when the optical path is long or due to space constraints, it is often necessary to use a mirror to fold the optical path. During the adjustment process, the position of the mirror is prone to shift, that is, the center position of the mirror will move, which will cause the total optical path of the optical system to change. Therefore, it is often necessary to precisely adjust the angle of the mirror during optical path experimental testing.

[0003] Currently, the common method for adjusting the reflector mechanism is to add adjusting shims and then grind the shims offline to adjust the angle. This method results in poor appearance, cumbersome debugging, and a long cycle.

[0004] Based on the above-mentioned technical problems, those skilled in the art urgently need to develop an online two-dimensional rotation adjustment device for a reflector that is simple in structure, has a shock absorption effect, and high adjustment accuracy. Summary of the Invention

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See Figure 1 , Figure 2 As shown;

[0037] The present invention provides an online two-dimensional rotation adjustment device for a reflector, the adjustment device comprising:

[0038] Supporting framework 1; and

[0039] The reflector assembly 2 is disposed within the support frame 1;

[0040] The orientation adjustment mechanism 3 installed on both sides of the reflector assembly 2 is used to adjust the tilt angle of the reflector assembly 2, and the end of the orientation adjustment mechanism 3 away from the reflector assembly 2 is connected to the support frame 1.

[0041] The regulating device also includes:

[0042] The pitch adjustment mechanism 4 has an adjustment end and an elastic end. The adjustment end is connected to the reflector assembly 2, and the elastic end is connected to the support frame 1.

[0043] As a further description of this embodiment, the support frame 1 includes a base 101; and

[0044] A side cover 102 is fixed to the base 101, and the side cover 102 provides lateral support for the orientation adjustment mechanism 3.

[0045] As a further description of this embodiment, the reflector assembly 2 includes a reflector chamber 201; and

[0046] The reflector 202 is installed in the reflector chamber 201 and is pressed by the reflector clamp 203.

[0047] As a further description of this embodiment, the orientation adjustment mechanism 3 includes a slide rail fixing seat 301; and

[0048] The orientation adjustment slider 302 is fixed to the slide rail fixing seat 301 by a rolling pin 303.

[0049] The orientation adjustment slide 304 and the positioning seat 308 are both fixed on the side cover 102 and cooperate with the orientation adjustment slider 302 to determine the direction of movement;

[0050] The reflector fixing pin 305 is fitted with the axial adjustment shim 306 on the orientation adjustment slider 302 with a clearance fit. The axial adjustment shim 306 plays the role of adjusting the axial displacement of the reflector chamber 201.

[0051] The orientation adjustment spring 307 is connected to the positioning seat 308 and the slide rail fixing seat 301, and elastically supports the slide rail fixing seat 301.

[0052] A sliding pin 310 is fixed to the positioning seat 308 and connected to the slide rail fixing seat 301. The orientation adjustment slider 302 drives the reflector chamber 201 to move via the reflector fixing pin 305. The reflector fixing pin 305 is clearance-fitted with both sides of the reflector chamber 201, allowing the axial adjustment shim 306 to contact the reflector chamber 201. The slide rail fixing seat 301 connects the sliding pin 310 and the orientation adjustment slider 302. The orientation rotation of the reflector is achieved through the movement of the slide rail fixing seat 301 on the sliding pin 310.

[0053] As a further description of this embodiment, the pitch adjustment mechanism 4 includes a pitch adjustment frame 401, one end of which is connected to the reflector assembly 2, and the other end is connected to the base 101 through a pitch adjustment spring 402.

[0054] The present invention discloses an online two-dimensional rotation adjustment device for a reflector. During operation, the movement of the slide drive block on the sliding pin 310 compresses the azimuth adjustment spring 307, causing the azimuth adjustment slider 302 to move along the azimuth adjustment slide 304 with the reflector chamber 201, thereby achieving precise adjustment of the reflector's azimuth angle. The pitch adjustment frame 401 compresses the pitch adjustment spring 402, causing the reflector 202 to rotate around the reflector fixing pin 305, thereby achieving precise adjustment of the reflector's pitch angle.

[0055] Because the two-dimensional rotation adjustment angle of the reflector 202 requires high precision, a theodolite or other precision measuring instrument is needed to directly measure the positional accuracy after each movement. The specific process is as follows: A crosshair is etched at the center of the reflector 202. The theodolite is aligned with the center of the reflector 202. The movement of the slide block on the sliding pin 310 compresses the azimuth adjustment spring 307, thus adjusting the azimuth angle of the reflector 202. The azimuth position of the crosshair is measured multiple times, and the azimuth position accuracy is calculated, thereby obtaining the azimuth adjustment accuracy of the reflector 202. The pitch adjustment frame 401 compresses the pitch adjustment spring 402, driving the pitch angle adjustment of the reflector 202. The pitch position of the crosshair is measured multiple times, and the pitch position accuracy is calculated, thereby obtaining the pitch adjustment accuracy of the reflector 202.

[0056] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
