Description

Technical Field

[0001] The utility model belongs to the technical field of solid laser brackets, and in particular relates to a butterfly-shaped crystal bracket. Background Art

[0002] In optical experiments and research, people usually need to use optical elements for observation and descriptive recording, especially now that optical research is becoming more and more meticulous and the accuracy requirements are getting higher and higher, so people have higher requirements for the stability of optical elements in experiments. In terms of function, the stability of optical elements in an optical system determines whether the performance of the entire optical system is stable, especially in laser systems, where the stability of its optical elements directly determines the energy, mode, polarization and other parameters of the output laser.

[0003] Optical components often face the problem of heating and deformation when working. Different materials have basically different mechanical properties for the same temperature change. Components that are in contact with each other are prone to stress distortion caused by temperature changes. Most of these changes are at the micron level.

[0004] In the application of solid-state laser technology, there are certain requirements for the clamping stability, integration, and adaptability of various slender optical components. Among them, structural stability and impact resistance are important performance requirements, which are related to the environmental applicability and longer service life of the laser. Existing clamping brackets often have the following problems:

[0005] 1. Insufficient clamping of slender optical components and poor clamping stability;

[0006] 2. When installing slender optical components to the bracket, the installation and alignment of the optical components takes a long time and is inefficient;

[0007] 3. For slender optical components, two clamps are often used to clamp them directly, which does not provide sufficient protection for the optical components. Utility Model Content

[0008] In view of the above-mentioned shortcomings, the utility model provides a butterfly-shaped crystal bracket, which uses a long strip cover plate to clamp the optical component, so that the optical component is fully clamped and fixed in its axial direction, and has high stability. Two alignment apertures are set at both ends of the optical component to facilitate adjusting the optical component to a suitable position, thereby improving the installation efficiency of the optical component. The aperture, the butterfly base and the cover plate enclose a protective space for the optical component to achieve protection of the optical component.

[0009] The utility model is realized by the following technical solutions:

[0010] A butterfly-shaped crystal bracket includes a butterfly-shaped base, a cover plate and an aperture.

[0016] Furthermore, a rubber fixing piece is installed under the cover plate to protect the optical components. A heat dissipation gap is provided between the optical components and the support block to improve the heat dissipation capacity of the optical components.

[0017] Furthermore, between the two support blocks, a rubber fixing piece is also laid on the butterfly plate to protect the optical components.

[0034] like Figures 1 to 5 A butterfly crystal support is shown, comprising a butterfly base 1, a cover plate 2 and an aperture 3. The butterfly base 1 comprises a butterfly plate 11 and two support blocks 12 protruding from the butterfly plate 11, a receiving groove 13 for receiving optical components is formed between the two support blocks 12, mounting holes 111 cooperating with the solid laser body are provided on the butterfly wings on both sides of the butterfly plate 11, and a threaded groove 121 is provided above the support block 12. The cover plate 2 is mounted on the top of the two support blocks 12, a through hole 21 cooperating with the threaded groove 121 is provided on the cover plate 2, and an adjusting bolt passes through the through hole 21 and is screwed into the threaded groove 121 to clamp and fix the optical components. Two apertures 3 are provided and mounted on the front and rear sides of the butterfly base 1, and an alignment hole 31 cooperating with the optical components is provided on the aperture 3 to facilitate adjustment of the installation position of the optical components and improve installation efficiency. The aperture 3, the butterfly base 1 and the cover plate 2 enclose a protective space for the optical components to protect the optical components.

[0035] In one embodiment, first, the butterfly plate 11 is installed on the device body of the solid laser device. Then, the optical component is installed in the receiving groove 13 between the two support blocks 12, and the installation position of the optical component is adjusted. Specifically, the optical component emits light, and the emitted light passes through the alignment holes 31 of the two apertures 3. According to the projection of the emitted light on the alignment holes 31, the specific position of the optical component is adjusted. It should be noted that a heat dissipation gap is provided between the optical component and the two support blocks 12, that is, the optical component does not contact the support blocks 12 on both sides thereof. After the alignment position is completed, the cover plate 2 is covered on top of the optical component, and the adjustment bolt passes through the through hole 21 and is screwed to the threaded groove 121 to fix the cover plate 2 to the upper position of the two support blocks 12. The cover plate 2 abuts against the optical component, so that there is a large friction force between the optical component and the cover plate 2, thereby realizing the friction fixation of the optical component. After installation, the optical components are located in a protective space formed by the aperture 3, the butterfly base 1 and the cover plate 2, so that the butterfly crystal bracket can play a protective role of wrapping the optical components.

[0036] Preferably, a positioning groove 112 is provided on the butterfly plate 11 , and a fixing hole 32 cooperating with the positioning groove 112 is provided below the diaphragm 3 . Each diaphragm 3 is provided with at least two fixing holes 32 to achieve installation and fixation between the diaphragm 3 and the butterfly plate 11 .

[0037] Preferably, a positioning groove 112 is provided on the butterfly plate 11, and a U-shaped hole 33 cooperating with the positioning groove 112 and a U-shaped groove 34 cooperating with the U-shaped hole 33 are provided below the diaphragm 3. The fastening bolt passes through the U-shaped hole 33 and is screwed into the positioning groove 112. When the diaphragm 3 is in a fixed state, the bolt head of the fastening bolt is located in the U-shaped groove 34, which is convenient for adjusting the position of the diaphragm 3 relative to the butterfly plate 11.

[0038] Preferably, each diaphragm 3 is provided with at least two U-shaped holes 33 to ensure the stability of the connection between the diaphragm 3 and the butterfly plate 11 .

[0039] In one embodiment, a fastening bolt can be used to penetrate the U-shaped groove 34 and the U-shaped hole 33 and screwed into the positioning groove 112 to fix the diaphragm 3. The U-shaped hole 33 is opened on the diaphragm 3 to help adjust the position of the diaphragm 3 relative to the butterfly plate 11.

[0040] Preferably, the cover plate 2 is further provided with a bolt groove 22 , which is coaxially arranged with the through hole 21 , and the bolt groove 22 can accommodate the bolt head of the adjusting bolt. The bolt head of the adjusting bolt sinks into the bolt groove 22 .

[0041] Preferably, each support block 12 is provided with at least two thread grooves 121 , and the number of the through holes 21 is consistent with the number of the thread grooves 121 , so as to achieve installation and docking between the cover plate 2 and the two support blocks 12 .

[0042] Preferably, a rubber fixing piece is installed under the cover plate 2 to protect the optical components. A heat dissipation gap is provided between the optical components and the support block 12 to improve the heat dissipation capacity of the optical components.

[0043] It should be noted that the butterfly crystal bracket mainly fixes the optical components through the friction between the optical components and the cover plate 2 and the butterfly plate 11.

[0044] Preferably, a rubber fixing piece is also laid on the butterfly plate 11 between the two support blocks 12 to protect the optical components.

[0045] Preferably, the butterfly base 1 and the cover plate 2 are made of nickel-steel alloy or polyimide material, which reduces the thermal expansion coefficient of the butterfly base 1 and the cover plate 2 and improves the stability of the optical component during operation.

[0046] It should be noted that nickel steel alloy is also known as Yin steel, commonly known as Yin steel in Chinese, which is a nickel steel alloy and a special steel containing 36% nickel. Due to its extremely small expansion coefficient, it is suitable for measuring components. Applying Yin steel to the production of the butterfly base 1 and the cover plate 2 can effectively reduce the deformation of the butterfly base 1 and the cover plate 2, thereby ensuring that the optical components have a good and stable working environment.

[0047] When the above-mentioned butterfly-shaped crystal bracket is used, the optical component is clamped by a long strip cover plate 2, so that the optical component is fully clamped and fixed in its axial direction, and the stability is high. Two alignment apertures 3 are arranged at both ends of the optical component to adjust the optical component to a suitable position and improve the installation efficiency of the optical component. The aperture 3, the butterfly base 1 and the cover plate 2 enclose a protective space for the optical component to protect the optical component.

[0048] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
