Description

Technical Field

[0001] The present invention relates to the technical field of optical equipment testing, in particular to a large-aperture, large-range, arc-second-level intense laser multi-optical axis parallelism testing machine. Background Art

[0002] Multi-optical-axis systems (such as high-energy laser weapons, space laser communications, precision optical aiming equipment, etc.) must ensure that the optical axes are strictly parallel to ensure energy concentration, signal transmission accuracy and system reliability.

[0003] However, when testing the parallelism of multi-axis systems, traditional parallelism testing equipment is limited by the following bottlenecks:

[0004] In scenarios involving large apertures (>200 mm), powerful lasers (>10 kW), and multiple optical axes (≥3 axes), existing equipment is not suitable for large-aperture testing. This is especially true when mounting a multi-axis product on a testing platform. If the device's light inlet is small, the number of optical axes required for testing will also be small, and the test range will be reduced. Furthermore, existing product mounting platforms are relatively limited in functionality. For example, conventional product mounting platforms only offer vertical or horizontal adjustment functions. The actual adjustment methods are relatively conventional and lack corresponding angle adjustment capabilities. Without the ability to change the tilt angle, position adjustment flexibility is poor, and the actual angle deviation control range will increase, which in turn affects the test range and even the test accuracy of the back-end test system.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

This large-aperture, large-range, arc-second-level high-intensity laser multi-axis parallelism tester, with its 400mm large-aperture light inlet, can simultaneously adjust the optical axis consistency of 2-10 groups of products, based on the 30mm aperture of conventional models, to achieve the purpose of multi-axis synchronous detection. Furthermore, with the help of a three-dimensional adjustment frame, it can perform three-dimensional adjustments on the products to be tested based on the requirements of up and down lifting, pitch, swing angle, and translation. Combined with the existing aiming system, it can increase the practicality of the entire tester while improving test accuracy.

[0020] 2.

[0034] Example 1

[0035] like Figures 1 to 4As shown, the large-aperture, large-range, arc-second-level strong laser multi-axis parallelism testing machine of this embodiment includes a light pipe body 4, a light inlet 3 at one end of the light pipe body 4, and a light outlet 5 at the other end of the light pipe body 4. The light pipe body 4 includes an off-axis parabolic primary mirror, a rotating mirror, a primary and secondary mirror base, a light pipe box, etc., which belongs to the conventional existing technology. A support platform 1 is provided at the end of the light pipe body 4 near the light inlet 3 to provide support for the actual product to be tested. The light diameter of the light inlet 3 is 400mm, and the focal length itself can be set to 9m. Referring to a conventional model product with an aperture of 30mm, the optical axis consistency of 2-10 groups of products can be adjusted at the same time to achieve the purpose of multi-axis synchronous detection. The support platform 1 A three-dimensional adjustment frame 2 is installed on the top of the support platform 1, which can realize the product position adjustment in three directions: up and down lifting, pitch angle and translation. A focal plane observation system 6 is installed inside the light outlet 5, which includes a CCD camera lens, a CCD camera, etc. A two-dimensional adjustment frame 8 is installed at the end of the light pipe body 4 near the light outlet 5. It is actually a conventional bracket structure with front and back and left and right position adjustment. A hole aperture plate 7 (a mature existing technology) is installed on the top of the two-dimensional adjustment frame 8; the three-dimensional adjustment frame 2 includes a base plate 37, a lifting platform 35 and an inclined plate 18. The base plate 37 is installed on the top of the support platform 1. A scissor lifting component 20 is installed on the top of the base plate 37. When it is pushed to one side by a torque, it can realize In order to achieve the height adjustment effect of up and down lifting, a lifting platform 35 is installed on the top of the scissor lifting component 20, which is affected by the scissor lifting component 20 to perform lifting and lowering movements. A rotating platform 19 is installed at the edge of the top surface of the lifting platform 35, and an inclined plate 18 is movably installed on the rotating platform 19. The two are axially connected so that the inclined plate 18 can rotate around the axis of the rotating platform 19 under force. A swing component is installed between the bottom of the inclined plate 18 on one side of the rotating platform 19 and the top of the lifting platform 35. The swing component provides the required power for the movement of the rotating platform 19. The top of the inclined plate 18 is movably installed with a table 17 through a sliding component (existing sliders, slide rails, etc.). The table 17 can be set as a table 17 is designed to be 800mm*800mm in size, and a light aiming system 23 is installed on the table 17. The light aiming system 23 is a conventional existing technology. The main body is a light absorbing cover, and the inner edge of the light absorbing cover is facing the light entrance 3. It is composed of an attenuation plate, an aiming system, etc. in sequence, and the aiming system includes conventional structures such as a rotating plane mirror, an imaging lens, and a four-quadrant detector; a second drive component 12 is installed at one end of the lifting platform 35 away from the rotating table 19, and a first drive component 11 is installed at one end of the bottom plate 37 below the second drive component 12, and a third drive component 14 is installed at the end of the inclined plate 18. The three drive components can provide the required power sources for the three movement directions of the three-dimensional adjustment frame 2 respectively.

[0036] Specifically, the second drive assembly 12 and the first drive assembly 11 are arranged in parallel up and down, and the staff can continue to operate the second drive assembly 12 and the first drive assembly 11 in the same position, and the second drive assembly 12 and the third drive assembly 14 are staggered up and down. In actual space, the positions of the second drive assembly 12 and the third drive assembly 14 are relatively vertical. The scissor lift assembly 20, the swing assembly and the sliding assembly are all equipped with an actuator assembly 13, which is a power actuator after receiving power, and the first drive assembly 11, the second drive assembly 12 and the third drive assembly 14 respectively provide power sources for the actuator assembly 13.

[0037] Furthermore, the swing assembly includes a sliding table 15 and a tightening table 16. The sliding table 15 is slidably installed on the top of the lifting platform 35 between the second drive assembly 12 and the rotating table 19. The sliding table 15 is driven by the actuator 13 to move left and right. The tightening table 16 is movably installed on the bottom of the inclined plate 18 on one side of the rotating table 19. The tightening table 16 and the sliding table 15 are in contact with each other up and down, and the contact surfaces are both inclined surfaces. Therefore, the cross-sections of the sliding table 15 and the tightening table 16 are approximately right-angled trapezoidal structural members. When the sliding table 15 and the tightening table 16 move relative to each other, an upward force is generated on the inclined plate 18, which can drive the inclined plate 18 to adjust the angle or even tilt and swing.

[0038] Furthermore, several supporting bases 9 are installed at the bottom of the light tube body 4. Since the focal length of the entire light tube body 4 is 9m, multiple supporting bases 9 are required for multi-position support, and vibration isolation feet 10 are installed between the supporting bases 9 and the light tube body 4 to achieve the purpose of shock absorption.

[0039] Furthermore, a plurality of mounting holes are provided at equal intervals on the top of the table 17, such as a plurality of 6 mm holes designed to be used for placing a variety of products to be tested, and the fixing operation is convenient, and a gantry 24 is installed at the edge of the top surface of the table 17 adjacent to the light inlet 3. The gantry 24 and the table 17 are detachably connected, and the optical aiming system 23 is installed on the gantry 24. Since the performance test of multi-optical axis parallelism is required, multiple sets of optical aiming systems 23 can be installed on the gantry 24.

[0040] It should be noted that when using this large-aperture, large-range, arc-second-level, high-intensity laser multi-axis parallelism tester, the products under test must first pass through the optical aiming system 23 for angular deviation adjustment. This system can detect angles within a ±0.1°-±6° range, and the detection results are displayed on the display in real time without delay. This allows for rapid angular adjustment of each product under test. After adjustment by the aiming system, the product's angular deviation is controlled within a ±0.2° range. The back-end testing system can meet the requirements for testing within a 0-±0.3° range. After calibration by the front-end aiming system, the product under test can be focused on the focal plane of the φ400mm, 9m, off-axis collimator at the back-end. A focal plane observation system, consisting of an optical lens and detector, observes the position of each focal point on the focal plane in real time without delay. Simultaneously, the positions of the products under test are adjusted to bring the focal points closer together, thereby reducing the optical axis deviation angle. Without computational software, the observation system's minimum observation spacing is approximately 0.1mm, corresponding to an optical axis angular deviation of 2.2° for the product under test. Testing accuracy can be further improved with the use of computational software compatible with the camera. In addition, specifically, when the table top 17 needs to be adjusted in height up and down, it is necessary to use the first drive component 11 to provide power for the actuator 13 of the scissor lift component 20, and with the help of the second drive component 12, the actuator 13 drives the sliding table 15 to move left and right. Based on the position change of the sliding table 15 relative to the tightening table 16, the inclination angle of the table top 17 is adjusted, and the third drive component 14 drives the table top 17 to make horizontal movements in the front and back directions.

[0041] Example 2

[0042] The structure of the large-aperture, large-range, angular-second-level, intense laser multi-axis parallelism tester of this embodiment is substantially the same as that of the large-aperture, large-range, angular-second-level, intense laser multi-axis parallelism tester of embodiment 1. The difference is that: an assembly slide 21 is installed at the bottom of the table 17. Unlike embodiment 1, the assembly slide 21 at this time is connected to the third drive assembly 14 by means of a sliding assembly. An assembly groove 26 (which can be designed as a T-slot) is provided on the top of the assembly slide 21. The assembly groove 26 is limitedly assembled with the bottom of the table 17, and one end of the assembly groove 26 is open. A limit slider can be provided at the bottom of the table 17. When installed on the assembly slide 21, the limit slider enters through the opening of the assembly groove 26, forming a limit assembly effect. The end of the assembly slide 21 away from the opening of the assembly groove 26 is installed with a top block 22. During installation, the top block 22 can be tightly pressed against one end of the table 17. The electromagnetic elastic member 25 is installed inside the assembly slide 21 adjacent to the opening of the assembly groove 26. The electromagnetic elastic member 25 is an existing electromagnetic block with elastic elasticity. After the top block 22 is tightly pressed against one end of the table 17, the electromagnetic elastic member 25 extends after power is cut off, and then moves upward, tightening and limiting the other side of the table 17, thereby achieving the installation effect of the table 17 (see Figure 5 and6 ).

[0043] Example 3

[0044] The structure of the large-aperture, large-range, angular-second-level, intense laser multi-axis parallelism tester of this embodiment is basically the same as the structure of the large-aperture, large-range, angular-second-level, intense laser multi-axis parallelism tester of embodiment 1 or 2. The difference is that the first drive assembly 11, the second drive assembly 12 and the third drive assembly 14 are all composed of a sliding sleeve 27, a clamping sleeve 36 and a screw head 34. The interior of the sliding sleeve 27 is provided with a through hole extending therethrough on the left and right sides. An insert shaft 32 is movably installed inside the through hole. The insert shaft 32 can move left and right along the through hole. A screw head 34 is installed at the end of the insert shaft 32 away from the actuator 13. The surface of the screw head 34 is provided with anti-slip grooves and can be manually driven to rotate. The inner side wall of the screw head 34 is provided with a clamping sleeve 36 via a bearing. When the screw head 34 rotates, the clamping sleeve 36 will not be affected by force (see Figure 7 and 8 ).

[0045] Specifically, the clamping sleeve 36 is a square structural part with one end larger than the other end, and a square inner groove is provided at the end of the sliding sleeve 27 adjacent to the clamping sleeve 36. After the clamping sleeve 36 is subjected to force, its small-sized end can be inserted into the square inner groove to form a limiting effect. A square shaft is installed at one end of the plug-in shaft 32 away from the screw head 34, such as being set as a square shaft part.

[0046] Furthermore, the three groups of actuator components 13 are all screw assemblies 28. The screw assembly 28 is a conventional existing technology and can convert rotational motion into linear motion. The sliders of the three groups of screw assemblies 28 are respectively connected to the scissor lift assembly 20, the sliding table 15 and the sliding assembly to provide horizontal force, and the screw ends of the screw assemblies 28 are all installed with sleeves 33. The end of the sleeve 33 is provided with a square inner groove, and the square inner groove is used in conjunction with the square shaft at one end of the plug shaft 32. The plug shaft 32 can be inserted into the sleeve 33 to form a limiting effect, and then when the sleeve 33 rotates, it can drive the sleeve 33 to move synchronously, thereby providing the required power source for the screw assembly 28.

[0047] Furthermore, a bracket is installed between the screw assembly 28 and the sleeve 27. The bracket mainly supports and installs the sleeve 27, and allows an operable gap to exist between the screw assembly 28 and the sleeve 27. A protective shell 30 is installed on the bracket. The square shaft and the sleeve shaft 33 are both inside the protective shell 30 for covering and protection. A servo motor 29 (equipped with a forward and reverse control circuit) is installed on the top of the protective shell 30. The servo motor 29 needs to be used in conjunction with the CNC system. The output shaft of the servo motor 29 extends into the protective shell 30, and a helical gear set 31 is installed between the output shaft of the servo motor 29 and the sleeve shaft 33. The helical gear set 31 is divided into a driving gear and a driven gear. The driving gear is installed on the output shaft of the servo motor 29, and the driven gear is installed on the sleeve shaft 33. The gear transmission ratio can be set to 10:1, thereby achieving the purpose of reduction transmission.

[0048] The method of using this embodiment is as follows: when using the three-dimensional adjustment frame 2, the actual usage situation needs to be considered. During the initial adjustment work, large-angle manual adjustment can be performed. It is only necessary to manually push the screw head 34 to move the clamping sleeve 36 forward. After the clamping sleeve 36 is limited and matched with the sliding sleeve 27, the end of the plug shaft 32 is inserted into the sleeve shaft 33 to form a limited connection, and then the screw head 34 is manually driven to rotate, so that the screw rotates synchronously. After the three groups of screw assemblies 28 are appropriately adjusted to a large angle, when high-precision adjustment is required, the screw head 34 is reset, the plug shaft 32 is separated from the sleeve shaft 33, and the servo motor 29 is controlled by the CNC system, and the transmission is performed with the help of the bevel gear set 31. Because the transmission is relatively large, the accuracy of the angle adjustment is relatively large, thereby improving the accuracy of the subsequent optical axis parallelism test.

[0049] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalent features for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
