Technical Field

[0002] Quality inspection of aviation parts is crucial to ensuring the safety and quality of aviation operations. With the continuous advancement of science and technology, the quality requirements for aviation parts are becoming higher and higher, and the quality inspection technology in production is also constantly innovating and optimizing to ensure the reliability and practicality of parts.

[0003] At present, the mainstream quality monitoring technologies on the market are mainly divided into manual and high-precision instruments. Manual and high-precision instruments are used to detect whether the overall shape of aviation parts meets the standards of standard aviation parts. However, such quality inspection methods are too single and can only mechanically give qualified or unqualified results. Detailed reasons for failure cannot be given, and thus, aviation parts cannot be repaired again, resulting in a waste of resources. At the same time, manual inspection relies on experience and has detection errors. High-precision instrument testing costs are too high and are not universal.

If a target image is formed on the light source baffle, adjust the light source angle;

[0082] S4 performs a second pressure test, and uses the second pressure test point as the starting point, uses a circular light source to perform a lighting test along the interception gap, and sets a light source baffle vertically in the direction of the light source. If a target image is formed on the light source baffle, adjust the light source angle.

[0083] See also Figure 2 The first pressure test is performed, and the first pressure test point is used as the starting point, a circular light source is used to perform a lighting test along the interception gap, and a light source baffle is set in the direction perpendicular to the light source. If a target image is formed on the light source baffle, the light source angle is adjusted, which specifically includes:

[0084] Respectively obtain the positions of the mold placed corresponding to the first pressure test point and the second pressure test point, and record them as the first position plane and the second position plane respectively;

[0085] Applying pressure to the aviation component along a direction perpendicular to the first position plane through a first pressure test point;

[0086] Connecting the first pressure test point and the second pressure test point to form a pressure test line segment;

[0087] On one side of the mold, a circular light source is arranged at a horizontal distance i from the first pressure test point, and on the other side of the mold, a light source baffle is arranged at a horizontal distance 3i from the mold. When the circular light source is illuminated without obstacles, the illumination image formed on the light source baffle is circular. The circular light source is adjusted to be horizontal and aligned with the pressure test section so that the light source illuminates from the first pressure test point to the second pressure test point along the interception gap;

[0088] iIt can be adjusted according to the size of aviation parts and actual conditions;

[0089] By placing the mold and the aviation parts for bonding, circular light sources and light source baffles are set on both sides of the mold, and the pressure points are selected to apply pressure to the aviation parts. According to the position of the gap between the mold and the aviation parts, the lighting angle of the circular light source is set, and the circular light source is moved along the gap track to perform lighting test on the entire gap. This can reduce manual operations, reduce the rate of manual misdetection, and improve test efficiency.

[0090] Adjust the circular light source to be horizontal and the angle between it and the pressure test section to 120 degrees. The angle between the circular light source and the pressure test section is recorded as the initial angle. Adjust the initial angle to the right along the horizontal direction in 10 degrees. When the cumulative adjustment angle is 120 degrees, end the angle adjustment.

[0091] Move the circular light source and the light source baffle from the first pressure test point to the second pressure test point along the interception gap, and obtain all light images on the light source baffle in real time through the light sensor;

[0095] The illumination sensor acquires all illumination images, and the illumination image closest to point c is selected as the pre-selected target image. If the distance between the pre-selected target image and point c is greater than P, the pre-selected target image is marked as a non-target image.

[0096] If the distance between the pre-selected target image and point c is less than or equal to P, the pre-selected target image is marked as the target image, the current target image position is marked by the light measuring instrument, and the first target position set is recorded, and the lighting angle is adjusted;

[0097] Mark the current position of the circular light source, adjust the lighting angle of the circular light source, and calculate the size of the intersection area between the circular lighting direction and the interception gap through the position change of the target image on the light source baffle.

[0098] See also Figure 3 , the circular light source illumination angle is adjusted, and the size of the intersection area between the circular illumination direction and the interception gap is calculated by the position change of the target image on the light source baffle:

[0099] Keep the initial angle of the current circular light source and adjust the vertical lighting angle;

[0100] Take the current circular light source's illumination direction as the horizontal line, keep the circular light source position unchanged, adjust the illumination angle upwards along the vertical direction until the angle between the circular light source's illumination direction and the horizontal line is 15 degrees for illumination testing, and adjust the illumination angle vertically downwards along the illumination direction with an adjustment range of 1 degree;

[0101] Determine whether all illumination images of the light source baffle are target images;

[0102] If it is a non-target image, adjust the lighting angle;

[0103] If it is a target image, the current target image position is marked by a light meter, and the second target position set is recorded to adjust the lighting angle;

[0104] Through a large amount of target position data, the size of the gap can be accurately measured to provide a basis for subsequent maintenance. This not only improves the accuracy of the data, but also reduces the detection cost and detection randomness, avoiding waste of resources.

[0105] If the cumulative adjustment of the illumination angle of the circular light source is 30 degrees, the vertical illumination angle adjustment is stopped.

The distance between all the light images and the base point is judged according to the light meter, and by comparing all distances with the light image distance threshold, the one that is less than the light image distance threshold and has the smallest distance is selected as the target image, and the target image position is recorded and entered into the set. After each horizontal angle adjustment, the current horizontal angle is kept unchanged, and the illumination angle is adjusted along the vertical direction to filter out the target image, and the target image position is recorded and entered into the set. By calculating the maximum value of the horizontal position set and the maximum value of the vertical position set, the maximum value is compared with the qualified gap threshold to determine the maximum gap direction, and the gap is tested for illumination at multiple angles to improve the comprehensiveness of the test, avoid the problem of not forming the target image due to angle problems, and further reduce the false detection rate.
