Description

Technical Field

[0001] The invention relates to the technical field of collimator testing, in particular to a primary and secondary mirror linking mechanism for a collimator. Background Art

[0002] Collimator is an important high-precision optical test instrument in optical experiments. It is mainly used to generate parallel light and simulate infinitely far targets. High-precision collimator is an indispensable measurement benchmark for the calibration and image quality inspection of infinite conjugate imaging optical systems such as photographic objective lenses and telescope objective lenses.

[0003] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:

[0004] However, the existing large-aperture and long-focal-length optical systems for collimator experiments are increasingly being used, which results in the increasing aperture of the primary mirror and the distance between the primary and secondary mirrors. For long-focal-length, large-aperture, and high-resolution collimators, in order to ensure the resolution of the light tube under the requirement of long focal length, the distance error between the primary and secondary mirrors of the light tube is required to reach the micron level. However, at present, a truss connection is usually adopted between the primary and secondary mirrors of the light tube. Since the truss material is mostly made of stainless steel or aluminum alloy, when the light tube system is in a temperature-changing environment, the distance error between the primary and secondary mirrors cannot be effectively guaranteed, resulting in a large distance between the primary and secondary mirrors, resulting in low resolution of the light tube system, poor imaging quality, etc., and a large error in adjusting the connection angle between the primary and secondary mirrors may cause the axes between the primary and secondary mirrors to be not on the same parallel line, thereby causing inaccurate experimental results of the collimator. Due to the gravity of the indium steel rod, the top of the support frame is affected by the external force brought along the y-axis during adjustment, which increases the difficulty of adjustment, thereby affecting the force on the indium steel rod.

[0005] Therefore, the above technical problems need to be solved. Summary of the invention

[0006] The object of the present invention is to provide a collimator primary-secondary mirror linking mechanism to solve the problems raised in the above background technology.

[0007] By adopting the above technical scheme, the problems of large errors in the light pipe system connected by a truss between the primary and secondary mirrors in a temperature-changing environment, resulting in low resolution of the light pipe system and poor imaging quality, and the like, are solved. At the same time, the problems of inaccurate results of parallel light pipe experiments caused by errors in angle adjustment of the primary and secondary mirrors and the influence of external forces brought by the indium steel connecting rod assembly along the y-axis on the top of the support frame during adjustment are solved, thereby affecting the force on the indium steel rod during the parallel light pipe experiment.

[0018] Compared with the prior art, the present invention provides a collimator primary and secondary mirror linking mechanism, which has the following beneficial effects:

[0019] 1. The present invention connects and fixes multiple groups of indium steel connecting rod assemblies through locking sleeves, and then fixes the indium steel connecting rod assemblies between the primary and secondary mirrors through the primary and secondary mirror assembly connecting blocks and joint bearings to link them. Due to the extremely low thermal expansion coefficient of the indium steel connecting rod assembly material, the indium steel connecting rod assembly is used to replace the traditional secondary mirror truss to control the relative positions of the primary and secondary mirrors, so that the indium steel connecting rod assembly uses a flexible guide flexible joint to release the radial and axial weak freedom of the indium steel rod, thereby improving the redundancy of the installation error of the indium steel connecting rod assembly and reducing the risk of jamming when the indium steel rod pulls the secondary mirror bracket to move slightly in the X direction under a temperature rise environment, effectively solving the problems of low resolution and poor imaging quality of the optical tube system;

[0020] 2. After the primary and secondary mirror assembly connection blocks are connected to the joint bearing, one end of the scale pointer is located at the top of the angle positioning disk. By adjusting the parallel angle between the primary and secondary mirrors, the scale pointer is rotated at the top of the angle positioning disk. The adjustment angle between the primary and secondary mirrors is observed through the angle line, so that the primary and secondary mirrors are more effectively adjusted to the parallel state of the light tube, avoiding the error caused by the primary and secondary mirrors when adjusting the angles, resulting in inaccurate results of the parallel light tube experiment;

[0021] 3. The present invention guides and supports the indium steel rod through a guiding flexible joint, and adjusts and supports the second screw between the lower bracket and the upper bracket by rotating the adjusting nut. At this time, the upper bracket slides on the outer side of the guiding limit rod to drive the upper bracket to move upward on the top of the lower bracket, so that the upward supporting force generated by the upper bracket and the gravity of the indium lever offset each other, avoiding the influence of the external force along the y-axis on the top of the support frame during adjustment, thereby affecting the force on the indium steel rod during the parallel light tube experiment.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a parallel light tube primary and secondary mirror connection mechanism.

[0034] See also Figure 1-Figure 9A collimator primary and secondary mirror linking mechanism comprises an indium steel connecting rod assembly 1, a secondary mirror support frame 2 movably mounted on one side of the indium steel connecting rod assembly 1, a primary mirror platform 3 movably mounted on the other side of the indium steel connecting rod assembly 1 and a base 5 movably mounted on the bottom of the indium steel connecting rod assembly 1, a locking sleeve 101 is rotatably mounted between multiple groups of indium steel connecting rod assemblies 1 through threads, and ends of the indium steel connecting rod assemblies 1 at both ends that are away from each other are rotatably linked with a joint bearing 103 through the locking sleeve 101, and the secondary mirror support frame 2 is connected to the primary mirror platform 3. A joint bearing 103 is fixedly installed on one side of the platform 3 that is close to each other and extends to the main and secondary mirror assembly connecting block 102 on the inner side. A first positioning pin 104 is installed between the main and secondary mirror assembly connecting block 102 and the joint bearing 103 through threaded rotation. An angle positioning disk 105 is fixedly installed on one side of the main and secondary mirror assembly connecting blocks 102 that are close to each other. Angle lines 106 are evenly distributed on the top of the angle positioning disk 105. A scale pointer 107 extending to the top of the angle positioning disk 105 is fixedly installed on the top of the joint bearing 103.

[0035] A lower bracket 4 is fixedly installed on the top of the base 5 by bolts, an upper bracket 401 is movably installed on the top of the lower bracket 4, and guide flexible joints 402 located at the bottom of the indium steel connecting rod assembly 1 are fixedly installed on both sides of the top of the upper bracket 401, and an adjusting nut 403 is rotatably installed between the lower bracket 4 and the upper bracket 401. A second screw rod 404 extending to the inside of the lower bracket 4 and the upper bracket 401 is fixedly installed at the top and bottom ends of the adjusting nut 403, and guide limit rods 405 penetrating the upper bracket 401 are fixedly installed at the front and rear ends of both sides of the top of the lower bracket 4.

[0036] Through the above-mentioned structural setting, the parallel light tube primary and secondary mirror linking mechanism connects and fixes multiple groups of indium steel connecting rod assemblies 1 through locking sleeves 101, and then fixes the indium steel connecting rod assembly 1 between the primary and secondary mirrors through the primary and secondary mirror assembly connecting block 102 and the joint bearing 103 to link them. Due to the extremely low thermal expansion coefficient of the indium steel connecting rod assembly 1 material, the indium steel connecting rod assembly 1 is used instead of the traditional secondary mirror truss to control the relative positions of the primary and secondary mirrors, so that the indium steel connecting rod assembly 1 uses a flexible guiding flexible joint 402 to release the radial and axial weak freedom of the indium steel rod, thereby improving the redundancy of the installation error of the indium steel connecting rod assembly 1 while reducing the risk of jamming when the indium steel rod pulls the secondary mirror bracket to move slightly in the X direction under a temperature rise environment, effectively solving the problems of low resolution and poor imaging quality of the optical tube system. Subsequently, after the joint bearing 103 is installed on the inner side of the primary and secondary mirror assembly connecting block 102, the scale pointer 107 is located on the top of the angle positioning disk 105, and the staff The angle between the primary and secondary mirrors is adjusted by observing the scale pointer 107 and the angle line 106, so that the primary and secondary mirrors are in a parallel state, and then the primary and secondary mirror assembly connecting block 102 is fixedly connected to the joint bearing 103 through the first positioning pin 104, so that the parallel angle of the primary and secondary mirrors is fixed, thereby avoiding the error caused by the angle adjustment of the primary and secondary mirrors, resulting in inaccurate results of the parallel light tube experiment. At this time, the indium steel connecting rod assembly 1 is located at the top of the guide flexible joint 402, and the indium steel connecting rod assembly 1 is supported by the lower bracket 4 and the upper bracket 401. By rotating the adjusting nut 403, the second screw rod 404 is extended inside the lower bracket 4 and the upper bracket 401, so that the upper bracket 401 moves upward at the top of the lower bracket 4, so that the supporting force of the upper bracket 401 and the gravity of the indium steel connecting rod assembly 1 offset each other, thereby avoiding the top of the support frame being affected by the external force brought along the y-axis during adjustment, thereby affecting the force on the indium steel rod during the parallel light tube experiment.

[0037] Furthermore, a contraction groove 201 is provided at the front and rear ends of the secondary mirror support frame 2, a support rod 202 is movably installed inside the contraction groove 201, a secondary mirror platform 203 is fixedly installed on the top of the support rod 202, a secondary mirror light pipe body 204 is fixedly installed on the top of the secondary mirror platform 203, and an electric telescopic rod 205 fixedly connected to the bottom of the secondary mirror platform 203 is fixedly installed on the inner side of the secondary mirror support frame 2;

[0038] Specifically, by extending and retracting the output end of the electric telescopic rod 205, the support rod 202 can move up and down inside the contraction groove 201 to adjust the height of the secondary mirror platform 203, so that the secondary mirror light tube body 204 can be adjusted to a suitable height for the parallel light tube experiment.

[0039] Further, a primary mirror support frame 301 is movably installed on the top of the primary mirror platform 3, a primary mirror light tube body 302 is rotatably installed between the primary mirror support frame 301 through a damping shaft, positioning blocks 303 are fixedly installed on both sides of the top of the primary mirror platform 3, a first screw rod 304 is rotatably installed on the inner side of the positioning block 303, a positioning sleeve plate 305 located on the inner side of the positioning block 303 is installed on the outer side of the first screw rod 304 through a threaded sleeve, a pressing block 306 is fixedly installed on one side of the positioning sleeve plate 305 close to each other, and positioning grooves 307 extending from the pressing block 306 to the inside are provided on both sides of the top of the primary mirror support frame 301;

[0040] Specifically, the staff installs the primary mirror support frame 301 on the top of the primary mirror platform 3, and by rotating the first screw rod 304, the positioning sleeve 305 can move downward on the outer side of the first screw rod 304, thereby driving the pressure block 306 to move downward and extend to the inside of the positioning groove 307, so as to position the primary mirror support frame 301 and install the primary mirror light tube body 302 at the center position of the primary mirror platform 3, so that the staff can adjust the axial focal length between the secondary mirror light tube body 204 and the primary mirror light tube body 302 conveniently.

[0041] Furthermore, a first slide groove 308 is provided inside the positioning block 303, and a first slider 309 fixed to the positioning sleeve 305 is slidably installed inside the first slide groove 308;

[0042] Specifically, when the positioning sleeve 305 moves inside the positioning block 303 , the first sliding block 309 slides inside the first sliding groove 308 , thereby making it more difficult for the positioning sleeve 305 to move.

[0043] Furthermore, the front and rear ends of both sides of the primary mirror support frame 301 are provided with limiting holes 310, the front and rear ends of both sides of the top of the primary mirror platform 3 are fixedly installed with primary mirror fixing components 311, and the interior of the primary mirror fixing component 311 is rotatably installed with a second positioning pin 312 extending into the limiting hole 310 through a threaded penetration;

[0044] Specifically, after the main mirror light tube body 302 is positioned and installed at the center position of the top of the main mirror platform 3, the second positioning pin 312 is rotated so that it extends to the inside of the limiting hole 310 through the thread, thereby fixing the main mirror support frame 301 on the top of the main mirror platform 3.

[0045] Further, fixing rods 406 are fixedly installed on both sides of the top of the adjusting nut 403, a support limit rod 407 is movably installed on one side of the fixing rod 406 away from each other, a limit slide rod 408 is movably installed on one end of the support limit rod 407 away from each other, a third screw rod 409 is rotatably installed inside the fixing rod 406, a through groove 410 is opened on one side of the fixing rod 406 away from each other, a collar 411 is installed on the outer side of the third screw rod 409 through a threaded sleeve, and the collar 411 passes through the through groove 410 and is fixedly connected to the support limit rod 407;

[0046] Specifically, by rotating the third screw rod 409, the ring 411 slides on the outside of the third screw rod 409 to drive the support limit rod 407 to move to the outside, and then the limit slide rod 408 slides at one end of the support limit rod 407 to the side where the support limit rod 407 is away from each other. At this time, the limit slide rod 408 is respectively located at the front end and the rear end of the guide limit rod 405, limiting the adjustment nut 403, thereby preventing the adjustment nut 403 from being automatically adjusted under the gravity of the indium steel connecting rod assembly 1. The upper bracket 401 is automatically rotated and contracted, thereby moving the upper bracket 401 downward, thereby reducing the supporting force of the upper bracket 401 on the indium steel connecting rod assembly 1. When the adjusting nut 403 needs to be rotated to adjust the height of the upper bracket 401, first slide the limiting slide bar 408 to the side where the supporting limiting rods 407 are close to each other, and then rotate the third screw rod 409 to make the ring 411 drive the supporting limiting rod 407 to move inward, so that the adjusting nut 403 can be freely rotated to adjust and support the height of the upper bracket 401.

[0047] Furthermore, a second slide groove 501 is provided at the front and rear ends of the top of the base 5, a second slider 502 is slidably installed inside the second slide groove 501, and a bracket unidirectional guide rail 503 fixedly connected to the bottom of the secondary mirror support frame 2 is fixedly installed on the top of the second slider 502;

[0048] Specifically, the second slider 502 slides inside the second slide groove 501, so that the bracket unidirectional guide rail 503 drives the secondary mirror support frame 2 to move on the top of the base 5, which makes it convenient for the staff to pull the secondary mirror support frame 2 to move slightly on the top of the base 5 through the indium steel connecting rod assembly 1.

[0049] Working principle: first, place the primary mirror support frame 301 in the middle position on the top of the primary mirror platform 3, and rotate the first screw rod 304 to make the positioning sleeve 305 move downward on the outside of the first screw rod 304. At this time, the first slider 309 slides inside the first slide groove 308, and the positioning sleeve 305 drives the pressure block 306 to move downward and slide into the positioning groove 307 to position the primary mirror support frame 301. Then, one end of the second positioning pin 312 is installed in the limiting hole 310 through threaded rotation, and the primary mirror support frame 301 is fixedly installed in the middle position on the top of the primary mirror platform 3. Multiple groups of indium steel connecting rod assemblies 1 are connected together through the locking sleeve 101, and then the locking sleeves 101 at both ends are connected to the joint bearing 103, and then the joint bearing 103 is installed in the main and secondary mirror assembly connecting block 102. At this time, the scale pointer 107 is located at the top of the angle positioning disk 105. By observing the angle between the angle line 106 and the scale pointer 107, the angle between the secondary mirror light tube body 204 and the primary mirror light tube body 302 is adjusted to make them parallel. Then the first positioning pin 104 is passed through the primary and secondary mirror assembly connecting block 102 and the joint bearing 103 to fix them. By rotating the adjusting nut 403, the second screw rod 404 is extended outward inside the indium steel connecting rod assembly 1 and the upper bracket 401, so that the upper bracket 401 moves upward on the outside of the guide limit rod 405 to support the indium steel connecting rod assembly 1. Then, the output end of the electric telescopic rod 205 is telescopically adjusted, so that the support rod 202 slides inside the contraction groove 201 to drive the secondary mirror light tube body 204 to adjust to a suitable height, and then the parallel light tube experiment can be carried out.
