Description

Technical Field

[0001] This application relates to the technical field of helium-neon laser tube installation, and more particularly to a novel adjustable helium-neon laser tube installation structure. Background Technology

[0002] Helium-neon lasers, as common gas lasers, play an important role in precision optical measurement, scientific research, and industrial testing. The helium-neon laser tube inside its optical resonant cavity serves as the gain medium and must be precisely installed and strictly aligned with the optical axis to ensure the quality of laser output.

[0003] Currently, helium-neon laser tubes are typically installed using rigid mounting methods, such as using metal or plastic clamps to hold them in place. While this method is simple in structure, it generally lacks flexible adjustment capabilities, making it difficult to achieve precise adjustments to the tube's position and angle during installation. This results in the optical path and cavity coaxiality being difficult to guarantee, which in turn affects the laser's performance.

[0004] Therefore, a novel adjustable helium-neon laser tube mounting structure is urgently needed to solve the above problems.

[0005] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Utility Model Content

[0006] The main objective of this application is to provide a novel adjustable helium-neon laser tube mounting structure, which solves the problem that existing helium-neon laser tubes typically use a rigid mounting method, which is not flexible enough in terms of position and angle adjustment, and makes it difficult to ensure that the optical path is strictly coaxial with the cavity.

[0007] To achieve the above objectives, this application provides a novel adjustable helium-neon laser tube mounting structure, comprising: a connecting flange for connecting to a gas chamber; A horizontal adjustment seat, one end of which is connected to the connecting flange; A locking assembly is disposed at the other end of the horizontal adjustment seat, the locking assembly including two locking blocks for locking the clamping sleeve; An adjusting block group includes multiple adjusting blocks connected to the locking blocks, the adjusting blocks being distributed in the vertical and horizontal directions of the two locking blocks; At least two clamping sleeves are built into the locking assembly for clamping the helium-neon laser tube; An angle adjustment component is fitted onto the clamping sleeve.

[0008] As a preferred embodiment of this application, the horizontal adjustment seat is provided with a first screw hole, and one end of the connecting flange is provided with a first oblong hole in the vertical direction, and the first screw hole is connected to the first oblong hole.

[0009] As a preferred embodiment of this application, the horizontal adjustment seat is provided with a second screw hole, and the locking assembly is provided with a second oblong hole in the horizontal direction, wherein the second screw hole is connected to the second oblong hole.

[0010] As a preferred embodiment of this application, the angle adjustment component includes a base and a top cover. The base is connected to the top cover. The top cover has a first set screw hole in the vertical direction, and the base has second set screw holes in the horizontal and vertical directions.

[0011] As a preferred embodiment of this application, the number of locking components is at least two, and the two locking components are respectively located at both ends of the clamping sleeve.

[0012] As a preferred embodiment of this application, the clamping sleeve is composed of two or more arc-shaped plates.

[0013] As a preferred embodiment of this application, the inner wall of the arc-shaped plate is provided with multiple rubber strips.

[0014] In a preferred embodiment of this application, the locking block and the adjusting block are connected by a first screw.

[0015] As a preferred embodiment of this application, the horizontal adjustment seat is provided with a mounting groove on one side of the connecting flange, and the connecting flange is located in the mounting groove.

[0016] As a preferred embodiment of this application, the two locking blocks are connected by a second screw.

[0017] This application provides a novel adjustable helium-neon laser tube mounting structure. By setting up a horizontal adjustment seat, a locking assembly, and fine-tuning blocks distributed in the vertical and horizontal directions, the operator can tighten or loosen the screws acting on the fine-tuning blocks. The screws generate precise pushing or pulling forces on the locking assembly, thereby achieving micro-adjustment of the position and orientation of the helium-neon laser tube in space. This adjustment process can ensure that the center of the light outlet of the helium-neon tube is strictly aligned with the light inlet of the gas chamber with micron-level precision. This effectively solves the problem of optical axis misalignment caused by insufficient adjustment capability in traditional installation methods, fundamentally ensuring the coaxiality of the laser resonator, and thus improving the quality and power stability of the output beam.

[0022] Please refer to Figure 1 , Figure 2 , Figure 3 In one embodiment, a novel adjustable helium-neon laser tube mounting structure includes: a connecting flange 1 for connecting to a gas chamber; a horizontal adjustment seat 2, one end of which is connected to the connecting flange 1; a locking assembly disposed at the other end of the horizontal adjustment seat 2, the locking assembly including two locking blocks 3 for locking clamping sleeves 5; a set of adjustment blocks 4, including multiple adjustment blocks 4 connected to the locking blocks 3, the adjustment blocks 4 being distributed in the vertical and horizontal directions of the two locking blocks 3; clamping sleeves 5, at least two in number, built into the locking assembly for clamping the helium-neon laser tube 12; and an angle adjustment assembly 6 disposed on the clamping sleeves 5.

[0023] Specifically, the two locking blocks 3 have horizontal grooves on the side near the horizontal adjustment seat 2, the horizontal adjustment seat 2 is located in the grooves, and the top and bottom of the horizontal adjustment seat 2 are in contact with the inner wall of the grooves.

[0024] Furthermore, the locking block 3 and the adjusting block 4 are connected by a first screw, and the two locking blocks 3 are connected by a second screw. It can be understood that the locking block 3 and the adjusting block 4 have first screw holes 10 at corresponding positions. The first screw passes through the first screw hole 10 to connect the locking block 3 and the adjusting block 4. The two locking blocks 3 are provided with corresponding second screw holes 11. The second screw passes through the second screw hole 11 and pulls the two locking blocks 3 tight, thereby achieving the locking of the clamping sleeve 5. Furthermore, it can be understood that the adjusting blocks 4 in the horizontal and vertical directions act on the locking blocks 3 through the screws at the top; when the screws on one side are tightened selectively and the screws on the opposite side are loosened accordingly, the unbalanced force applied to the locking blocks 3 will form a small torque, forcing the entire "locking block 3-clamping sleeve 5 laser-helium-neon tube 12" assembly to deflect extremely slightly around a virtual fulcrum; this angular displacement is amplified into a considerable linear displacement at the light outlet of the helium-neon laser tube 12, which has a certain lever arm; by repeating this operation in two orthogonal directions respectively, the three-dimensional coordinates of the light outlet of the helium-neon laser tube 12 in space can be finely adjusted until its beam center and the light inlet of the gas chamber are precisely coaxial, and finally all screws are tightened.

[0025] It is understood that by setting up a horizontal adjustment seat 2, a locking assembly, and fine-tuning blocks distributed in the vertical and horizontal directions, the operator can tighten or loosen the screws acting on the fine-tuning blocks to generate precise pushing or pulling forces on the locking assembly, thereby achieving a minute adjustment of the position and attitude of the helium-neon laser tube 12 in space. This adjustment process can ensure that the center of the light outlet of the helium-neon tube is strictly aligned with the light inlet of the gas chamber with micron-level precision, effectively solving the problem of optical axis misalignment caused by insufficient adjustment capability in traditional installation methods, fundamentally ensuring the coaxiality of the laser resonant cavity, and thus improving the quality and power stability of the output beam.

[0026] Specifically, please refer to Figure 1 , Figure 2 Based on the above embodiments, the horizontal adjustment seat 2 is provided with a first screw hole, and one end of the connecting flange 1 is provided with a first oblong hole 7 in the vertical direction. The first screw hole is connected to the first oblong hole 7. Furthermore, the horizontal adjustment seat 2 is provided with a second screw hole, and the locking assembly is provided with a second oblong hole 8 in the horizontal direction, and the second screw hole is connected to the second oblong hole 8.

[0027] I understand, please refer to Figure 2The core function of the first oblong hole 7 and the second oblong hole 8 is to provide preliminary and wide-range position adjustment capability for the installation of the helium-neon laser tube 12. The first oblong hole 7 is set on the connecting flange 1 and extends vertically. By cooperating with the first screw hole on the horizontal adjustment seat 2, the connecting flange 1 and the entire installation structure can be coarsely adjusted and positioned in the vertical direction. The second oblong hole 8 is set on the locking assembly and extends horizontally. By cooperating with the second screw hole on the horizontal adjustment seat 2, the locking assembly and the laser tube it holds can be coarsely adjusted and positioned in the horizontal direction.

[0028] Specifically, please refer to Figure 1 Based on the above embodiments, the number of locking components is at least two, and the two locking components are respectively located at both ends of the clamping sleeve 5 to enhance stability.

[0029] Specifically, please refer to Figure 2 , Figure 3 Based on the above embodiments, the clamping sleeve 5 is composed of two or more arc-shaped plates, and multiple rubber strips 9 are arranged around the inner wall of the arc-shaped plates.

[0030] It is understood that in this embodiment, the clamping sleeve 5 is composed of two semi-circular tubes, and multiple rubber strips 9 are arranged around the inner wall of the two semi-circular tubes. The material of the rubber strips 9 can be either silicone or fluororubber. Through this structural design, the helium-neon tube can be evenly covered and buffered when locked. This can provide sufficient friction and support, and avoid hard contact between metal and glass, preventing the helium-neon tube from breaking due to local stress during installation or debugging.

[0031] Specifically, please refer to Figure 2 Based on the above embodiments, the angle adjustment component 6 includes a base 61 and an upper cover 62. The base 61 is connected to the upper cover 62. The upper cover 62 has a first set screw hole 13 in the vertical direction, and the base 61 has a second set screw hole 14 in the horizontal and vertical directions.

[0032] It is understood that in this embodiment, there are a total of four setscrew holes, including the first setcrew hole 13 and the second setcrew hole 14. The angle adjustment component 6 applies force to the outer circle of the semi-circular tube through the four setcrews. Since the clamping sleeve 5 has a built-in flexible structure, the small amount of push of the setcrew will cause a slight elastic deformation of the whole, thereby driving the helium-neon tube to achieve angle deflection. The deflection amount can be continuously adjusted within a very small range to ensure high-precision alignment between the laser tube optical axis and the optical system.

[0033] Specifically, based on the above embodiments, the horizontal adjustment seat 2 is provided with a vertical mounting groove on one side of the connecting flange 1, and the connecting flange 1 is located in the mounting groove. It can be understood that the mounting groove provides a clear assembly reference and limit for the connecting flange 1, ensuring that the two are quickly aligned during installation and effectively avoiding positional deviation during the assembly process.

[0034] In summary, it can be understood that the present invention provides a novel adjustable helium-neon laser tube mounting structure for achieving stable clamping and multi-degree-of-freedom precise adjustment of the helium-neon laser tube 12, ensuring that its optical axis is strictly coaxial with the laser gas chamber. The structure mainly includes a connecting flange 1, a horizontal adjusting seat 2, a locking assembly, four sets of adjusting blocks, a clamping sleeve 5, and an angle adjusting assembly 6; wherein, the connecting flange 1 is used to install and connect with the gas chamber; one end of the horizontal adjusting seat 2 is connected to the connecting flange 1, and the other end is equipped with a locking assembly; The locking assembly consists of two locking blocks 3, which together cover and lock the clamping sleeve 5. There are no fewer than two clamping sleeves 5, which are used to directly clamp the helium-neon laser tube 12. The sleeve itself can be composed of two or more arc-shaped plates, and multiple rubber strips 9 can be arranged around the inner wall to effectively protect the glass tube while providing uniform clamping force. The adjusting block 4 group includes multiple adjusting blocks 4 distributed in the vertical and horizontal directions of the locking block 3. They are connected to the locking block 3 by screws and can precisely push the locking assembly at the micrometer level, thereby realizing the fine adjustment of the laser tube's position in space. In specific implementation, the horizontal adjustment seat 2 is provided with a first screw hole, which cooperates with the first oblong hole 7 in the vertical direction at the end of the connecting flange 1 to realize vertical adjustment and fixation; the horizontal adjustment seat 2 is also provided with a second screw hole, which cooperates with the second oblong hole 8 in the horizontal direction on the locking assembly to realize horizontal adjustment. In addition, the angle adjustment component 6 set on the clamping sleeve 5 includes a base 61 and a top cover 62. The top cover 62 has a first set screw hole 13 in the vertical direction, and the base 61 has a second set screw hole 14 in the horizontal and vertical directions. The set screws enable fine adjustment of the pitch and yaw angles of the laser tube. The locking components are preferably two, which are respectively arranged at both ends of the clamping sleeve 5 to enhance stability. Furthermore, the locking blocks 3 are connected by a second screw to provide a uniform locking force. The horizontal adjusting seat 2 has a mounting groove on one side of the connecting flange 1, into which the connecting flange 1 is embedded, further improving the rigidity and assembly accuracy of the overall structure; This installation structure, through the coordinated operation of multiple adjustment mechanisms, balances rigid fixation with flexible protection, effectively solving problems such as difficulty in adjustment, easy damage to the glass tube, and insufficient centering accuracy in traditional installation methods, and significantly improving the assembly quality and working performance of the helium-neon laser.
