Description

TECHNICAL FIELD

[0001] The present application relates to the field of aviation technology, in particular to a structure and method for bonding and simultaneously calibrating the angle of a plane mirror. BACKGROUND

[0002] The aviation load is limited by the volume and weight of the spherical cabin. In optical system design, mirrors are often used to turn the light path, which not only makes the entire optical-mechanical system space compact, improves the strength of the entire machine, and reduces the weight, but also makes the envelope space fully utilized by changing the light path direction. Therefore, there may be several to tens of mirrors in an optical system. Although changing the light path direction does not affect optical imaging, the face type precision of the mirror itself greatly affects the optical imaging effect after reflection. Therefore, in a multi-mirror optical system, the support structure design, processing, and adjustment of the mirror are particularly important.

[0003] Currently, the installation method of small plane mirrors on engineering equipment is to install the mirror in the mirror frame and then press the edge of the mirror with a pressure ring. In this installation method, the mirror surface is pressed by the mechanical pressure ring, and it is difficult to guarantee the face type precision. Another support method is to bond the edge of the mirror with the mirror frame through RTV silicone rubber, and the glue becomes an integral part after curing. However, during assembly integration, the angle of the mirror often needs to be calibrated by a theodolite. During the calibration process, two methods are commonly used. The first method is to change the angle of the mirror by grinding the contact surface angle of the gasket between the mirror frame and the mirror frame mounting seat. The second method is to change the angle of the mirror by directly placing a thin gasket at the screwing position of the mirror seat. However, in both methods, the mirror frame will be deformed due to the height difference in the flatness of the mirror frame mounting surface when the screw is tightened, which will further reduce the face type precision of the mirror.

[0031] In addition, the technical features involved in the different embodiments of the application described below can be combined with each other as long as there is no conflict.

[0032] As Figures 1-8 The structure for bonding and angle calibration of a plane mirror comprises a frame 1 and an infrared return assembly 4, the frame 1 is provided with a cover plate 2, the infrared return assembly 4 comprises a flexible lens pressing ring, a mirror frame 9 and a mirror 11, the mirror 11 is arranged on the mirror frame 9, the mirror frame 9 is arranged on the frame 1, the flexible lens pressing ring is arranged on the mirror frame 9 and above the mirror 11, the flexible lens pressing ring is in contact with the mirror 11, a needle gauge 7 is further arranged between the mirror 11 and the mirror frame 9, the needle gauge 7 is arranged on the flexible lens pressing ring, and a glue injection hole 13 is further arranged on the mirror frame 9, the glue injection hole 13 corresponds in position to the needle gauge 7, in order to facilitate the display of the internal structure, therefore the cover plate 2 in the attached Figure 1 The cover plate 2 in the attached

[0033] The structure for simultaneously bonding and calibrating the angle of the plane mirror utilizes the flexible lens pressing ring and the mirror frame 9 to axially position the mirror 11, sets the pin gauge 7 in the radial direction of the mirror 11, and when injecting glue through the glue injection hole 13, the area and thickness of the glue are accurately controlled, and then the pulling force distribution on the mirror surface of the mirror 11 after the glue solidifies is uniform, effectively avoiding the local surface type being excessively pulled due to the local surface type of the mirror 11 being excessively pulled, and realizing the simultaneous bonding and angle calibration of the mirror 11, thereby ensuring the surface type precision of the mirror 11. The cover plate 2 can effectively prevent light leakage and avoid the influence of stray light on the imaging quality.

[0034] As shown in Figures 5-7 , in the embodiment, the flexible lens pressing ring is a flange pressing ring 8, the flange pressing ring 8 is arranged on the mirror frame 9, and the flange pressing ring 8 is located above the mirror 11. The flange pressing ring 8 is in contact with the mirror 11, and the flange pressing ring 8 is provided with flexible grooves 15 staggered thereon. Three mechanical stops are uniformly arranged on the outer ring of the flange pressing ring 8, and the mechanical stops are matched with screws to fixedly install the flange pressing ring 8 on the mirror frame 9. At the same time, the flange pressing ring 8 is in contact with the mirror 11 to axially position and install the mirror 11. The flexible grooves 15 are processed by electric spark slow wire cutting. When the flange pressing ring 8 extrudes the lens of the mirror 11, the flexible grooves 15 have a damping unloading compression force. The staggered arrangement of the plurality of flexible grooves 15 can effectively disperse the compression force, so as to fix the position of the lens of the mirror 11 and prevent the lens of the mirror 11 from being deformed due to uneven force distribution.

[0035] As shown in Figure 5 and Figure 7 , in the embodiment, the flexible groove 15 includes a circular portion 16 and a strip-shaped portion 17. The circular portion 16 is arranged at both ends of the strip-shaped portion 17, and the strip-shaped portion 17 penetrates through the circular portion 16. The cross-sectional diameter of the circular portion 16 is greater than the width of the strip-shaped portion 17, and both ends are designed in a circular structure. When the flexible groove 15 is deformed under stress, the two ends will not have a local large stress, thereby preventing the two ends from being easily torn. The penetration design of the strip-shaped portion 17 and the circular portion 16 ensures the structural stability of the flexible groove 15, and then effectively unloads the compression force while ensuring the axial positioning of the mirror 11.

[0036] As shown in Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, in the embodiment, the structure further comprises a grinding gasket 10, which is arranged between the mirror frame 9 and the frame 1; three mechanical stops are uniformly arranged on the outer ring of the mirror frame 9, and the mechanical stops are connected with the frame 1 through screws to fixedly connect the mirror frame 9 and the frame 1, and the grinding gasket 10 is arranged at the connection position of the mechanical stop and the frame 1; when angle calibration is performed, the angle of the mirror 11 is adjusted by grinding the grinding gasket 10, so as to complete the angle calibration.

[0037] As shown in Figure 5 , Figure 6 and Figure 8 , in the embodiment, the structure further comprises a boss 18, which is arranged on the mirror frame 9; the boss 18 is uniformly arranged at intervals of 120 degrees on the inside of the mirror frame 9, and the boss 18 is arranged at the bottom of the mirror frame 9 and used to contact the mirror 11 to form axial limiting of the bottom; the boss 18 is uniformly arranged at intervals of 120 degrees to realize three-point support of the mirror 11, and three points determine a plane to ensure the flatness of the mirror 11 during installation.

[0038] As shown in Figure 5 , Figure 6 and Figure 8 , in the embodiment, the boss 18 is an arc-shaped structure, and the top of the mirror frame 9 is provided with a chamfer structure; the arc-shaped boss 18 can better fit the mirror frame 9 to ensure that the mirror 11 is stably and steadily installed into the mirror frame 9, and the two ends of the boss 18 are also processed into an arc-shaped structure; this design reduces the application of materials and thus reduces the weight of the overall structure, but also ensures the stability and flatness of the installation of the mirror 11; the chamfer structure at the top of the mirror frame 9 is arranged at the inner ring position of the installation port of the mirror frame 9; the chamfer structure reduces the risk of collision between the mirror 11 and the mirror frame 9 during installation, thereby damaging the mirror 11, improves the safety measures and safety of the installation process, and also helps to reduce the weight of the mirror frame 9 to realize lightweight design of the structure.

[0039] As shown in Figures 4-8As shown, in the embodiment, the flange pressing ring 8 is provided with needle hole grooves 12 corresponding to the needle gauges 7, and the needle gauges 7 are arranged on the needle hole grooves 12; the needle hole grooves 12 are arranged on the flange pressing ring 8 in pairs, and each pair of needle hole grooves 12 is arranged uniformly with an interval of 120 degrees; the upper half of the needle gauge 7 is in the needle hole groove 12, and the lower half of the needle gauge 7 is between the mirror 11 and the mirror frame 9; the needle hole groove 12 and the needle gauge 7 are matched with each other to ensure the installation of the needle gauge 7, and each pair of needle hole grooves 12 is arranged uniformly with an interval of 120 degrees to ensure that the radial gap between the mirror 11 and the mirror frame 9 is uniform and equal after assembly; moreover, since the glue injection hole 13 corresponds to the position of the needle gauge 7, the thickness uniformity of the glue layer 6 and the bonding area are limited by the existence of the pair of needle gauges 7 and the upper flange pressing ring 8 when the glue is injected through the glue injection hole 13, and the glue overflow does not occur, the forming quality of the glue layer 6 is accurately controlled, the glue is EC2216-B / A epoxy resin glue, and the thickness of the glue layer 6 is 0.15 mm, so that the bonding quality can be ensured, the distribution of the pulling force on the mirror surface of the mirror 11 after the glue layer 6 is solidified is uniform, and the local surface type is prevented from being pulled too large to cause the surface type precision of the mirror 11 to be reduced.

[0040] As shown in the figure, Figures 1-3 In the embodiment, the structure further includes a light splitting assembly 3 and a visible light folding assembly 5, and the light splitting assembly 3 and the visible light folding assembly 5 are arranged on the frame 1; the structure and principle of the light splitting assembly 3 and the visible light folding assembly 5 are the same as those of the infrared light folding assembly 4, so the bonding process is the same as that of the infrared light folding assembly 4, wherein the visible light folding assembly 5 is also installed on the frame 1 through mechanical stop and screw cooperation, and the light splitting assembly 3 is also installed in the frame 1 in the same way to realize the light splitting function, the difference lies in that the positions and placement relationships of the light splitting assembly 3 and the visible light folding assembly 5 are different from those of the infrared light folding assembly 4, when the angle calibration is performed, the arrow direction in the figure corresponds to the light path advancing direction, wherein the included angle between the light splitting mirror reflecting surface on the light splitting assembly 3 and the reference end surface 14, or the included angle between the light splitting mirror reflecting surface and the incident light is 45 degrees, the included angle between the light after being split by the light splitting mirror on the light splitting assembly 3 and the light emitted by the mirror 11 on the infrared light folding assembly 4 is 90 degrees, similarly, the included angle between the light after being split by the light splitting mirror on the light splitting assembly 3 and the light emitted by the mirror 11 on the visible light folding assembly 5 is also 90 degrees, and the included angle between the light emitted by the mirror 11 on the visible light folding assembly 5 and the light after being split by the light splitting mirror on the light splitting assembly 3 is 90 degrees.

[0042] Specifically, first, the mirror 11 is installed in the mirror frame 9, the convex boss 18 is in contact with the mirror 11 to form a limit, the flange pressing ring 8 is installed above the mirror 11, the flange pressing ring 8 is in contact with the mirror 11, the flange pressing ring 8 is connected with the mirror frame 9 through the mechanical stop, then three pairs of needle gauges 7 are inserted into the mirror 11 and the mirror frame 9 from the flange pressing ring 8 along the needle hole slot 12, at this time, the gap between the mirror 11 and the mirror frame 9 is designed to be 0.15mm±0.01mm, then the EC2216-B / A epoxy resin glue is injected through the glue injection hole 13 by using a syringe, due to the existence of the paired needle gauges 7 and the upper flange pressing ring 8, the thickness uniformity of the glue layer 6 and the bonding area are limited to be equal, and the glue overflow does not occur, the forming quality of the glue layer 6 is accurately controlled, after being still for 2 hours, when the glue appears to be solidified but not completely solidified, the mirror frame 9 is installed on the frame 1, then the angle of the mirror 11 is calibrated, since the structure and principle of the light splitting assembly 3 and the visible return assembly 5 and the infrared return assembly 4 are the same, the above-mentioned method is also applicable to the light splitting assembly 3 and the visible return assembly 5, the light splitting assembly 3 and the visible return assembly 5 are bonded and installed on the frame 1 according to the same method, then the light splitting assembly 3, the infrared return assembly 4 and the visible return assembly 5 are calibrated, the calibration steps are as follows: the light splitting assembly 3, the infrared return assembly 4 and the visible return assembly 5 all use the self-collimation function of the theodolite to calibrate the angle with the reference end face 14 as the reference, Figure 3 The arrow direction in the figure corresponds to the light path advancing direction, the light is vertically incident from the light inlet 19 which is perpendicular to the end face of the reference end face 14, first, the included angle between the reflecting surface of the light splitting mirror of the light splitting assembly 3 and the reference end face 14 is calibrated to be 45 degrees through the self-collimation function of the theodolite, Then, the light is split by the light splitting assembly 3, the middle wave infrared band transmits through the light splitting mirror and irradiates on the mirror 11 of the infrared return assembly 4, the included angle between the light after splitting by the light splitting mirror of the light splitting assembly 3 and the light emitted from the mirror 11 of the infrared return assembly 4 is calibrated through the self-collimation function of the theodolite, The visible waveband is reflected by the spectroscope to the mirror 11 of the visible return assembly 5, and the angle between the light after being split by the spectroscope of the spectroscope assembly 3 and the light reflected by the mirror 11 of the visible return assembly 5 is 90 degrees The angle between the light reflected by the mirror 11 of the visible return assembly 5 and the light after being split by the spectroscope of the spectroscope assembly 3 is 90 degrees The angle is 90 degrees, and after 24 hours of static state, the pin gauge 7 is taken out after the glue is completely solidified;

Moreover, the mirror 11 and the mirror frame 9 are installed in the stable relative position through the axial and radial positioning. In the angle calibration process, even if the relative position of the mirror 11 and the mirror frame 9 changes due to the screwing of the screw, the mirror surface type will not be affected because the glue has not been completely solidified and the glue and the mirror lens do not produce pulling stress. The angle calibration and bonding of the mirror 11 are simultaneously performed, the structure deformation caused by the screwing of the screw of the mirror frame 9 after the glue solidification is avoided, the decline of the mirror surface type precision is avoided, and the dependence on the assembly and adjustment level of the assembly and adjustment personnel is reduced.
