Problems solved by technology

For example, if the conduit gap does not meet the technical standards, it may cause a system to leak pressure, liquid, or even a flight safety accident, resulting in personnel and major economic losses.
Therefore, the measurement of the catheter gap is particularly important; the traditional measurement methods include gap hook measurement and visual measurement by the staff based on experience. When the gap hook measures the gap, it is sometimes unable to measure the catheter gap due to the influence of the narrow space range, and the gap hook cannot be measured. The specific gap value; the visual measurement method needs to rely on rich experience and certain eyesight to estimate, and the specific gap value cannot be measured and the estimation is often inaccurate; the traditional method of measuring the gap between catheters is affected by the measurement space and human factors, and the measurement is not accurate. Accurate, large error, cumbersome operation
[0003] At present, there is no special device to solve the problems referred to above

Embodiment 1

[0037] A device for detecting the clearance of aviation conduits, which is in contact with the conduits 1 and 2 to be tested, such as figure 1 , figure 2 As shown, it includes an upper detection device 29, a lower detection device 30, a Y-axis displacement sensor 31 connected between the upper detection device 29 and the lower detection device 30;

[0038] It also includes a slide rail group, an X-axis displacement sensor group, and a probe group; the slide rail group is divided into an upper detection slide rail arranged in the upper detection device 29 and a lower detection slide rail arranged in the lower detection device 30;

[0039] The upper detection slide rail is divided into the first slide rail 7, the second slide rail 8, and the third slide rail 9; the lower detection slide rail is divided into the fourth slide rail 10, the fifth slide rail 11, and the sixth slide rail 12. The outside of the first slide rail 7, the second slide rail 8, the third slide rail 9, the ...

Embodiment 2

[0051] This embodiment also proposes a method for detecting the gap of the aviation catheter, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, when the upper conduit 36 ​​and the lower conduit 37 are on the same vertical plane, turn on the switch one 13 and close the switch two 14 to lock the rotation of the telescopic rotating shaft 15, and press the button one 25 to perform calculations on the same vertical plane. And the first probe 1, the second probe 2, the third probe 3, the fourth probe 4, the fifth probe 5, and the sixth probe 6 are in the initial position by the reset button 27, and the first probe is set. The detection tip positions of needle 1, second probe 2, third probe 3, fourth probe 4, fifth probe 5, and sixth probe 6 are point A, point B, point C, point D, Point E, point F; take the direction of the telescopic shaft 15 as the Y-axis direction, and the pointing direction of the first probe 1 as the X-axis, and record points A, B, C,...

Embodiment 3

[0058] This embodiment also proposes a method for detecting the gap of the aviation catheter, such as figure 1 , figure 2 , image 3 , Figure 6 , Figure 7 As shown, when the upper conduit 36 ​​and the lower conduit 37 are not on the same vertical plane, turn on the switch one 13 and turn on the switch two 14 to realize the rotation of the telescopic rotating shaft 15, so that the first probe 1, the second probe 2, the third probe The needle 3 is perpendicular to the axis of the upper conduit 36, the fourth probe 4, the fifth probe 5, and the sixth probe 6 are perpendicular to the axis of the lower conduit 37; press the reset button 27 to control the first probe 1. The second probe 2, the third probe 3, the fourth probe 4, the fifth probe 5, and the sixth probe 6 are in the initial position, and the axis direction of the telescopic shaft 15 is the Y-axis direction, and the first probe The pointing direction of needle 1 is the direction of X1 axis to construct the X1-Y ax...

Description

technical field [0001] The invention belongs to the field of aviation catheter detection, and in particular relates to a device and method for detecting gaps in aviation catheters. Background technique [0002] During the installation of conduits in the aviation field, due to factors such as manufacturing errors and assembly errors, the conduit gap does not meet the technical standards. Whether the conduit gap meets the technical standards directly affects aviation safety. For example, if the conduit gap does not meet the technical standards, it may cause a system to leak pressure, liquid, or even a flight safety accident, resulting in personnel and major economic losses. Therefore, the measurement of the catheter gap is particularly important; the traditional measurement methods include gap hook measurement and visual measurement by the staff based on experience. When the gap hook measures the gap, it is sometimes unable to measure the catheter gap due to the influence of t...
