[0048] As Figure 4 , Figure 5 and Figure 6 shown, in some embodiments provided by the present application, the support column assembly 300 includes a first support column 310 and a second support column 320. One end of the first support column 310 is screwed to the base 400, and the other end passes through the through hole 210 and is screwed to the second support column 320. Specifically, a first threaded hole 401 is provided on the upper surface of the base 400, and a first threaded rod 311 is provided at one end of the first support column 310, and the first threaded hole 401 and the first threaded rod 311 are correspondingly matched. In this embodiment, the first support column 310 and the base, and the first support column 310 and the second support column 320 are all installed by threaded docking, which is convenient for disassembly, mutually universal, and easy to use.

[0049] The present application provides two types of screwing forms in the above embodiments: As Figure 4 shown, for the first type, a second threaded rod 312 is provided at the other end of the first support column 310, and a third threaded hole 321 corresponding to the second threaded rod 312 is provided at one end of the second support column 320; the first support column 310 and the second support column 320 are respectively arranged on both sides of the gyro adapter plate 200 and are in contact with the gyro adapter plate 200; and, as Figure 5 shown, for the second type, a built-in second threaded hole 313 is provided at the other end of the first support column 310, and a third threaded rod 322 corresponding to the second threaded hole 313 is provided at one end of the second support column 320; the first support column 310 and the second support column 320 are respectively arranged on both sides of the gyro adapter plate 200 and are in contact with the gyro adapter plate 200.

[0050] As Figure 2 , Figure 4 and Figure 5As shown, in some embodiments provided by the present application, a radially symmetric notch 314 is provided on the side surface of the first support column 310. The notch 314 on the side surface of the first support column 310 has an anti-slip effect when using a wrench for fixed rotation.

Ensure that when the 50-type laser gyroscope 100 is horizontally installed or vertically placed, the 50-type laser gyroscope 100 can be stably placed in the accommodation space between the gyro adapter plate 200 and the base 400, facilitating wiring potting or semiconductor mounting on each side of the 50-type laser gyroscope.

[0052] As Figure 2 shown, in some embodiments provided by the present application, the end surface of several support column assemblies 300 away from the base 400 is a placement surface. In this embodiment, the 50-type laser gyroscope 100 can be turned over and stably placed horizontally.

[0053] As Figure 2 shown, in some embodiments provided by the present application, the projection plane of the gyro adapter plate 200 is located within the upper surface of the base 400. In this embodiment, during the assembly and turning process of the 50-type laser gyroscope 100, the contact surface between the assembly plane and the tooling provided by the present application remains the lower bottom surface and the side surface of the base, and the 50-type laser gyroscope 100 does not contact the assembly plane to avoid causing bumps and damages to the laser gyroscope.

[0054] The following uses specific embodiments to illustrate the 50-type laser gyroscope assembly tooling provided by the present application:

[0055] Embodiment 1

[0056] A 50-type laser gyroscope assembly tooling includes a gyroscope adapter plate 200 corresponding and matching with an external 50-type laser gyroscope 100, four support column assemblies 300, and a base 400; a first threaded hole 401 is provided on the upper surface of the base 400. The support column assembly 300 includes a first support column 310 and a second support column 320. A first threaded rod 311 is provided at one end of the first support column 310, and the first threaded rod 311 is perpendicularly connected to the first threaded hole 401 of the base 400. Second threaded rods 312 at the other end of the first support column 310 respectively pass through four through holes 210 on the periphery of the gyroscope adapter plate 200 and are perpendicularly connected to third threaded holes 321 provided inside one end of the second support column 320. After the second threaded rods 312 and the third threaded holes 321 are screwed together, the first support column 310 and the second support column 320 are respectively arranged on both sides of the gyroscope adapter plate 200 and are in contact with the gyroscope adapter plate 200. Among them, the base 400 and the support column assembly 300 can be made of aluminum alloy materials such as 2A12. The thickness of the base 400 > 30 mm to ensure that the tooling is stable and not prone to tipping during the assembly of the gyroscope. The outer diameter of the first support column 310 should not be designed too large, and it should be ensured that the minimum clearance between the first support column 310 and the laser gyroscope > 2 mm. The length of the first support column 310 should not be too short, and it should be ensured that the minimum clearance between the tooling base 400 and the laser gyroscope > 30 mm; to ensure that a receiving space for accommodating the 50-type laser gyroscope 100 is formed between the gyroscope adapter plate 200 and the base 400.

[0057] In this embodiment, the dimensional markings of each part of the base 400, the first support column 310, and the second support column 320 are as Figures 6 - 10 shown, and the specific data of each dimension are shown in Table 1 below:

[0058] Table 1 Dimensional Table of the 50-Type Laser Gyroscope Assembly Tooling in Embodiment 1

[0059] Dimension Number A B C D E Value (mm) 130 130 40 10 67 Dimension Number F G H I J Value (mm) 62 M4 84 Ф8 8 Dimension Number K L M N O Value (mm) 60 8 Ф4 10 6 Dimension Number P Q R S T Value (mm) 20 M4 M4 80 Ф8 Dimension Number U V Value (mm) 10 M4

[0060] When using this embodiment, first vertically connect the first threaded rod 311 at one end of the first support column 310 to the first threaded hole 401 of the base 400. Then align the through hole 210 on the gyro adapter plate 200 with the second threaded rod 312 at the other end of the first support column 310. Next, vertically connect the third threaded hole 321 provided inside one end of the second support column 320 to the second threaded rod 312, and the tooling completes the fixation of the gyro adapter plate 200. Place the 50-type laser gyro 100 from below the gyro adapter plate 200, and use the mounting screw 001 of the gyro to pass through the corresponding mounting hole of the gyro adapter plate 200 to align and fix the 50-type laser gyro 100 with the gyro adapter plate 200. During this process, the 50-type laser gyro assembly tooling provided by this application can fix the gyro adapter plate 200 during the assembly process of the 50-type laser gyro, effectively solving the problem that it is difficult to align and install the gyro during the assembly of the 50-type laser gyro. The designed length and width of the base 400 and the connection height of the first support column 310 and the second support column 320 are appropriate to ensure that there is no interference between the 50-type laser gyro 100 and the base 400, the first support column 310 and the installation plane, and to avoid knocking and damaging the gyro. When using a rotary tool such as a wrench to rotatably and fixedly connect the first support column 310 and the base 400, the radially symmetric notches 314 provided on its side have an anti-slip effect, ensuring a stable rotation process without slipping.

[0061] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
