DETAILED DESCRIPTION

[0036] Reference Figures 1 to 3 The present invention provides a technical solution: an automatic detection device for producing fiber optic gyroscopes, comprising:

[0037] Base 1, fixed on the workbench;

[0038] A first rotating frame 2 is rotatably disposed on the base 1 and driven by a first motor fixed inside the base 1;

[0039] A second rotating frame 4 is rotatably arranged at an end of the first rotating frame 2 away from the base 1 and driven by a second motor 3;

[0040] A third rotating frame 5 is rotatably disposed in the second rotating frame 4 and driven by a third motor 6; and

[0041] The positioning assembly 7 is detachably mounted inside the third rotating frame 5 .

[0042] It should be noted that the base 1, the first rotating frame 2, the second rotating frame 4 and the third rotating frame 5 together constitute a detection turntable, and when detecting the three-axis fiber optic gyroscope, the rotation axis of the first rotating frame 2 is always taken as the center. The detection axis position of the three-axis fiber optic gyroscope is made to be aligned with the rotation axis of the first rotating frame 2 by adjusting the second rotating frame 4 and the third rotating frame 5, thereby performing three-axis detection. When detecting the single-axis fiber optic gyroscope, the rotation axis of the third rotating frame 5 is made to be in the same position as the rotation axis of the first rotating frame 2 by adjusting the second rotating frame 4. During detection, the angular displacement is detected by rotating the third rotating frame 5. At the same time, the first rotating frame 2 can simulate the angular velocity of the earth's rotation, thereby reducing the error caused by the earth's rotation during long-term detection and improving the detection accuracy.

[0043] In this embodiment, the positioning component 7 includes:

[0044] The positioning frame 71 has four positioning blocks 72 symmetrically and slidably arranged on its outer wall, and a compression spring is arranged between the positioning blocks 72 and the positioning frame 71;

[0045] The limiting components are configured into two groups and are slidably disposed on the outer wall of the positioning frame 71;

[0046] A clamping assembly, configured as four, slidably disposed on the inner wall of the positioning frame 71; and

[0047] The baffle 77 is configured as two pieces, which are symmetrically and detachably installed on both sides of the positioning frame 71 .

[0048] As a preferred embodiment, the four corners of the positioning frame 71 are provided with limiting grooves 73, and pads are detachably installed in the limiting grooves 73. The limiting components are slidably set on the limiting grooves 73. The four inner walls of the positioning frame 71 are provided with sliding grooves. The clamping components are slidably set in the sliding grooves and are limited by baffles 77.

[0049] As a preferred embodiment, the limit assembly includes:

[0050] A positioning plate 75, slidably disposed on the positioning frame 71;

[0051] A sliding block, slidably disposed in the limiting groove 73 and fixed to the inner wall of the positioning plate 75; and

[0052] The adjusting bolt 76 is threadedly connected to the four corners of the positioning plate 75 , and one end thereof is in contact with the third rotating frame 5 .

[0053] That is to say, the positioning block 72 can make the up-down and left-right directions of the positioning component 7 located at the center of the third rotating frame 5, and the positioning plate 75 and the pad block can make the front and rear positions of the positioning component 7 located at the center of the third rotating frame 5, thereby improving the versatility during installation. It should be noted that the applicable scope of the positioning component 7 is within the detection turntable with a relatively small size difference, so as to avoid the detection turntable being too large or too small to affect the installation.

[0054] As a preferred embodiment, the clamping assembly includes:

[0055] The clamping column 78 is configured as a plurality of columns and is slidably disposed in the positioning frame 71;

[0056] A clamping spring connected between the clamping column 78 and the positioning frame 71; and

[0057] The limiting plate 74 is slidably disposed in the positioning frame 71 and is limited by the baffle 77 .

[0058] Among them, multiple clamping columns 78 can ensure that the up and down and left and right positions of the fiber optic gyroscope when installed are in the center position of the positioning frame 71. It should be noted that the front and back positions of the fiber optic gyroscope are adjusted by increasing or decreasing the number of pads in the limit groove 73.

[0059] As a preferred embodiment, the limiting plate 74 includes:

[0060] The sliding plate 1 741 is configured as two, symmetrically and slidably disposed in the sliding groove;

[0061] The second sliding plate 742 is configured as a plurality of sliding plates, slidably disposed in the sliding groove, and each of the sliding plates is located between the two first sliding plates 741; and

[0062] The guide column 744 is slidably disposed between the first sliding plate 741 and the second sliding plate 742 and between multiple second sliding plates 742 .

[0063] As a preferred embodiment, a plurality of limiting holes 743 are provided between the two sliding plates 741 and the plurality of sliding plates 742, and the limiting holes 743 are sleeved on the clamping column 78, and when the plurality of limiting holes 743 are joined, an elliptical hole is formed together to limit the clamping column 78.

[0064] That is to say, after the fiber optic gyroscope is placed in the positioning frame 71 and clamped by the clamping column 78, the baffles 77 are installed on both sides of the positioning frame 71 to squeeze the limit plate 74 so that it limits the clamping column 78 to avoid vibration during detection.

[0065] Specifically, first, place the positioning frame 71 in the third rotating frame 5, and make it preliminarily positioned by the positioning block 72, then put the fiber optic gyroscope into the positioning frame 71 and clamp it by the clamping column 78, so that the front and rear positions of the fiber optic gyroscope are close to the middle position of the positioning frame 71 when placing it, and then the positioning plate 75 is sleeved on the positioning frame 71 through the limiting groove 73, and the baffle 77 is installed on both sides of the positioning frame 71, and the positioning plate 75 and the limiting plate 74 are limited, and then the front and rear positions of the positioning assembly 7 are centered by placing a pad in the limiting groove 73 and adjusting the adjusting bolt 76 to improve the accuracy of the detection.

[0066] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
