Description

Technical Field

[0001] This invention relates to an optical mirror fixing and connecting device. Background Technology

[0002] Optical imaging elements can be broadly classified into two categories: lenses and mirrors. Both lenses and mirrors involve the issue of how to fix them to structural components. Common methods for fixing lenses include edge rolling, clamping, elastic elements, adhesive bonding, or a combination of several methods.

[0003] The rolling method involves mounting the lens in a metal frame and then bending the frame edge on a precision lathe using a special tool. This causes the frame to bend and deform, tilting along the lens edge to tightly wrap around the lens, thus connecting the lens to the frame. This method is typically suitable for smaller lenses. The clamping ring method uses a clamping ring to press the lens firmly into the frame. The clamping ring usually uses external threads to secure the lens; if structural dimensions are limited, internal threads are used. If space allows, an elastic shim can be added between the lens and the clamping ring to ensure even force distribution. This method is often used for larger diameter lenses. The elastic element method uses wire clips to fix the lens or other optical elements to the frame. This is generally used in applications where rigidity requirements are low, but not in environments with vibration or other mechanical requirements. The adhesive method uses adhesives such as epoxy resin or silicone to bond the lens to the frame.

[0004] Mirrors are typically fixed to the frame and structural components using screws. Mirrors are generally divided into two categories: glass mirrors and metal mirrors. Metal mirrors have the optical mirror and frame integrated, while glass mirrors require adhesive bonding to the frame, which is then secured to the flange of the structural component using screws. Because the flatness of the frame and flange cannot be perfect (typically on the order of a few micrometers), stress is generated on the frame when it is screwed onto the flange. This stress is transmitted to the optical mirror, causing surface deterioration and affecting image quality. Current methods reduce the structural thickness between the frame and the mirror to create an elastic element, reducing the frame's stiffness and thus decreasing stress transmission to the mirror, thereby minimizing surface deterioration. This method can reduce the impact of installation stress on the surface shape of the optical mirror to a certain extent, thus meeting the usage requirements. However, it is necessary to repeatedly iterate and optimize the elastic element to seek a balance between stiffness and deflection. On the one hand, it must meet the requirements of the optical mirror surface shape, and on the other hand, it must meet the requirements of the mechanical environment. Once the balance is broken, the surface shape requirements will be met, but the mechanical environment requirements will not be met. Therefore, plastic deformation or even breakage of the mirror mount often occurs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The present invention provides an optical mirror fixing connection device that can simultaneously meet the requirements of optical mirror surface shape and mechanical environment.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0007] An optical mirror fixing and connecting device, the device includes an optical mirror body, an adjustment spacer, a mounting base plate and a fastening system;

[0008] The optical mirror body is the object to be mounted and fixed, consisting of the optical mirror and the mirror base. The mirror base consists of a mirror frame, mounting flanges, locating pin holes, and mounting screw through holes. The mounting flanges include one first mounting flange and two second mounting flanges. The three mounting flanges are evenly arranged. A locating pin hole is provided in the middle of all mounting flanges. Mounting screw through holes are provided on both sides of the locating pin hole of the first mounting flange.

[0009] The adjusting spacer includes upper and lower surfaces. The upper surface is divided into two parts with a height difference. Three locating pin holes are evenly arranged on the adjusting spacer. The higher part corresponds to the first mounting flange. One of the locating pin holes is located in the middle of the higher part, corresponding to the locating pin hole of the first mounting flange. First mounting screw holes are provided on both sides of the locating pin hole in the higher part. The two first mounting screw holes are located on the higher part and correspond to the mounting screw through holes provided on both sides of the locating pin hole of the first mounting flange. Three second mounting screw holes are also evenly distributed on the adjusting spacer.

[0010] The mounting base is used for mounting the optical mirror body and has corresponding positioning pin holes, first mounting screw holes and second mounting screw holes. The three positioning pin holes of the mounting base are corresponding to the three positioning pin holes of the optical mirror body and the three positioning pin holes of the adjusting spacer. The first mounting screw hole of the mounting base is corresponding to the first mounting screw hole of the adjusting spacer and the mounting screw through hole of the optical mirror body. The second mounting screw hole of the mounting base is corresponding to the second mounting screw hole of the adjusting spacer.

[0011] The fastening system includes a positioning pin and a first mounting screw that pass through the optical mirror body, the adjusting spacer and the mounting base, and also includes a second mounting screw for fixing the adjusting spacer to the mounting base and adhesive between the optical mirror body and the adjusting spacer.

[0012] The optical mirror body and the adjusting spacer are placed sequentially on the mounting base. The height between the optical mirror body and the upper surface of the mounting base is measured to determine the amount of adjustment required for the adjusting spacer. The thickness of the adjusting spacer is adjusted to the correct position. After applying adhesive to the positioning pins, they are inserted into the positioning pin holes of the mounting base. After the adhesive dries, the adjusting spacer and the optical mirror body are placed on the positioning pins in sequence. The first mounting screw for fixing the optical mirror body is tightened, and the second mounting screw for fixing the adjusting spacer is tightened. Under the natural force of the optical mirror body, adhesive is applied between the other two second mounting flanges of the optical mirror body mount and the adjusting spacer. After the adhesive dries, the connection is completed.

[0013] Further: If the optical mirror is made of metal, the mirror and the frame of the base are one piece; if the optical mirror is made of glass, the mirror needs to be glued to the frame of the base.

[0014] Further: The adjusting spacer consists of two surfaces, an upper surface and a lower surface. The upper surface is divided into two parts with different heights, the difference between which is greater than 10 micrometers and between 100 micrometers. The lower surface is a flat surface used to adjust the thickness of the spacer, ensuring that the height between the optical mirror of the upper measuring optical mirror body and the mounting substrate meets the design requirements. Two first mounting screw holes near the positioning pin holes are used to fix the first mounting screws through which the optical mirror body restricts the degree of freedom in the direction parallel to the optical axis. Three evenly distributed second mounting screw holes are used to fix the second mounting screws to fix the adjusting spacer on the mounting substrate. Three positioning pin holes are used to insert positioning pins into the positioning pin holes of the mounting substrate to restrict the degree of freedom of the optical mirror body perpendicular to the optical axis.

[0015] Further: The mounting base plate is composed of an upper surface, a lower surface, a positioning pin hole, a first mounting screw hole, and a second mounting screw hole. The positioning pin hole is used for installing the positioning pin to restrict the degree of freedom of the optical mirror body perpendicular to the optical axis. The two first mounting screw holes close to the positioning pin hole are used to install the optical mirror body and the adjustment spacer onto the mounting base plate. The three evenly distributed second mounting screw holes are used to install the adjustment spacer onto the mounting base plate.

[0016] The advantages of this invention compared to existing technologies are: by constraining the rotation of the optical mirror body with positioning pins and filling the unevenness between the mounting flange and the adjusting spacer of the optical mirror body with adhesive, no installation stress is generated while fixing the mirror, thus solving the over-positioning problem, eliminating the elastic element, and ensuring both mechanical environmental adaptability and the optical mirror surface shape. This invention provides a method and apparatus for fixing optical mirrors, enabling the fixed installation of reflectors, including metal reflectors and glass reflectors. Where structural space permits, it can also be applied to lens mounting and other applications. Attached Figure Description

Detailed Implementation

[0023] Figure 1 This is a description of the final installation effect of the optical mirror fixing and connecting device of the present invention. Figure 2 An optical mirror fixing method and apparatus of the present invention are described in general form using exploded views. Figure 3 It provides a detailed description of the main structure of the optical mirror. Figure 4Description of the adjusting spacer: The entire device consists of four parts: optical mirror body 1, adjusting spacer 2, mounting base 3, and fastening system. The optical mirror body 1 and adjusting spacer 2 are placed sequentially on the mounting base 3. The height between the optical mirror 1A of the optical mirror body 1 and the upper surface 3A of the mounting base is measured to determine the required thickness of the adjusting spacer 2. The thickness of the adjusting spacer 2 is then adjusted accordingly. After applying adhesive to the positioning pins 4, they are inserted into the positioning pin holes 3D of the mounting flanges of the mounting base 3. After the adhesive dries, the positioning pin holes 1D of the first mounting flange 1B of the optical mirror body 1 are aligned with the positioning pin holes 2D of the mounting surface 2A of the adjusting spacer 2, and the adjusting spacer 2 and optical mirror body 1 are placed on top of each other, aligned with the positioning pins 4. The first fixing screw 5 of the optical mirror body 1 is tightened, and the second fixing screw 6 of the adjusting spacer is tightened. Under natural stress, adhesive is applied between the remaining two mounting flanges 1C of the optical mirror body 1 and the remaining mounting surfaces 2B of the adjusting spacer. After the adhesive dries, the connection is complete. Three positioning pins 4 are responsible for positioning the optical mirror body 1 in the direction perpendicular to the optical axis, and two first fixing screws 5 of the optical mirror body 1 are responsible for positioning the optical mirror body 1 in the direction parallel to the optical axis. Since only the local area of ​​the first mounting flange 1B of the optical mirror body 1 is fixed, there is no over-positioning. The other two second mounting flanges 1C of the optical mirror body 1 and the other mounting surfaces 2B of the adjusting spacer are constrained in the direction of the optical axis by applying adhesive. Since the adhesive fills the gap between the two second mounting flanges 1C and 2B, it does not introduce installation stress caused by the flatness between the mounting flanges 1B and 1C of the optical mirror body 1 and the mounting surfaces 2A and 2B of the adjusting spacer 2 while fixing them, thus solving the over-positioning problem, eliminating the elastic element, and ensuring mechanical environmental adaptability while ensuring the optical mirror surface shape.

[0024] The present invention relates to an optical mirror body of a method and apparatus for fixing an optical mirror.

[0025] The optical mirror body 1 is the object to be mounted and fixed. It consists of an optical mirror 1A and a mirror base. The mirror base consists of a mirror frame 1F, a first mounting flange 1B, and two second mounting flanges 1C. The two second mounting flanges 1C have the same structure. The three mounting flanges are evenly arranged on the circumference of the optical mirror 1A. Each of the three mounting flanges has a locating pin hole 1D, which is located in the middle of each mounting flange. The first mounting flange 1B has two mounting screw through holes 1E, which are located on both sides of the locating pin hole 1D. If the optical mirror 1A is made of metal, the mirror 1A and the mirror frame 1F of the mirror base are integrated. If the optical mirror 1A is made of glass, the mirror 1A needs to be glued and fixed to the mirror frame 1F of the mirror base.

[0026] The present invention relates to an adjustment spacer for a method and apparatus for fixing an optical mirror.

[0027] The adjusting spacer 2 consists of two surfaces: the upper surface is divided into mounting surface 2A and mounting surface 2B, with mounting surface 2A slightly higher than mounting surface 2B by a height difference of 10 to 100 micrometers. The lower surface 2C is a flat plane used to refine the thickness of the spacer 2, ensuring that the height between the optical mirror 1A of the upper measuring optical mirror body 1 and the mounting base flange 3A meets the design requirements. The first mounting screw hole 2E is located on the upper surface 2A of the adjusting spacer 2. The first fixing screw 5 passes through the first mounting screw hole 2E and the mounting screw through hole 1E of the optical mirror body 1, restricting the degree of freedom of the optical mirror body 1 in the direction parallel to the optical axis. The second fixing screw 6 passes through the second mounting screw hole 2F and the second mounting screw hole 3F of the mounting base 3, fixing the adjusting spacer 2 to the mounting base 3. The locating pin 4 is inserted into the locating pin hole 2D of the adjusting spacer 2, the locating pin hole 3D of the mounting base 3, and the locating pin hole 1D of the mounting flange, restricting the degree of freedom of the optical mirror body 1 perpendicular to the optical axis.

[0028] The present invention relates to a mounting substrate for a method and apparatus for fixing optical mirrors.

[0029] The mounting base 3 can be a flat hollow disk or a complex cylindrical shape. The mounting base 3 consists of an upper surface 3A and a lower surface 3B. The locating pin hole 3D is used to install the locating pin 4, restricting the degree of freedom of the optical mirror body 1 perpendicular to the optical axis. The first mounting screw hole 3E is used to install the optical mirror body 1 and the adjusting spacer 2 onto the mounting base 3, and the second mounting screw hole 3F is used to install the adjusting spacer 2 onto the mounting base 3.

[0030] The present invention relates to a fastening system for a method and apparatus for fixing optical mirrors.

[0031] The fastening system includes a positioning pin 4 and a first mounting screw 5 that pass through the optical mirror body 1, the adjusting spacer 2, and the mounting base 3. It also includes a second mounting screw 6 for fixing the adjusting spacer 2 to the mounting base 3 and adhesive between the optical mirror body 1 and the adjusting spacer 2. The positioning pin 4 passes through a positioning pin hole 1D in the optical mirror body 1, a positioning pin hole 2D in the adjusting spacer 2, and a positioning pin hole 3D in the mounting base 3. The first mounting screw 5 passes through a mounting screw through hole 1E in the optical mirror body 1, a first mounting screw hole 2E in the adjusting spacer 2, and a first mounting screw hole 3E in the mounting base 3. The second mounting screw 6 passes through a second mounting screw hole 2F in the adjusting spacer 2 and a second mounting screw hole 3F in the mounting base 3.
