Example Embodiment
[0029] Such as figure 1 with 2 Shown, a three-axis fiber optic gyroscope structure includes a main body 1, a first gyroscope 2, a second gyroscope 3, a third gyroscope 4, a first circuit box 5, a second circuit box 6, and a third circuit box 7. , Add meter component 8, shock absorber 10 and external plug-in 11; image 3 As shown, the main body 1 is a hexahedral frame and the material is aluminum alloy 2A12. The first gyroscope 2, the third gyroscope 4, and the second gyroscope 3 are all fiber optic gyroscopes, which are fixedly connected to the three surfaces of the body 1 in orthogonal positions, and their axial directions are respectively x, y, and y in the rectangular coordinate system. The shape and position tolerances of the z-axis and pairwise perpendicularity are all less than 0.05. The second gyroscope 3 is located on the top surface. The external plug-ins of the gyroscope assembly are all placed in the top plane of the assembly for circuit connection with external dev...
