Description

Technical Field

[0001] The utility model relates to the technical field of aviation material detection, in particular to a deformation detection tool for aviation composite materials. Background Art

[0002] The fairing is a component installed between the fuselage and the wing to reduce the wing-body interference drag and increase the aircraft's range. In order to ensure that the quality of the produced fairings meets the standards, the fairings need to be inspected regularly, including the flatness of their surface. In the prior art, the degree of deformation is mainly determined by detecting the depressions or protrusions on the surface of the fairing using testing instruments.

[0003] The Chinese utility model patent with announcement number CN219736248U discloses a deformation detection device for a composite wing-body fairing of aviation, which fixes the fairing by setting a protective shell and a third baffle on the base, and then drives the detection structure composed of a first slide bar, a sphere, a rack, a gear, a pointer and a scale line to move laterally along the surface of the fairing through a driving mechanism set on the base, and contacts the fairing through the sphere, thereby detecting the convexity and concavity of the surface of the fairing. However, the scheme has the following problems: it can only detect the area on a straight line of the fairing during one clamping. When it is necessary to detect other areas of the fairing, it is necessary to clamp the fairing for the second time and adjust the angle and position of the fairing. The position of the second clamping is difficult to control to completely overlap with the position of the first clamping, which will cause the error to increase further, thereby affecting the accuracy of the detection, and finally causing the detection data to deviate from the actual value.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0045] See also Figure 1-Figure 5 The utility model provides a technical solution: an aviation composite material deformation detection tool, comprising:

[0046] A base 1 and a clamping assembly disposed at the upper end of the base 1 for positioning the fairing 29;

[0047] At least one detection component for detecting the flatness of the surface of the fairing 29;

[0048] A moving assembly for driving the detection component to move laterally along the surface of the fairing 29;

[0049] At least one bracket 2 is arranged at the upper end of the base 1; a frame 8 is provided with a rotating shaft 7, the rotating shaft 7 is rotatably connected to the rotating groove provided in the bracket 2, and the frame 8 is connected to the moving component;

[0051] The above technical solution can add rotational adjustment on the basis of the original lateral adjustment of the detection component, ensuring that the detection range can cover the remaining positions of the fairing 29. During operation, after the detection component completes the detection of a straight line of the fairing 29, the driving component drives the moving component connected to the frame 8 to rotate, so that the detection component connected to the moving component rotates synchronously around the fairing 29, thereby adjusting the detection position of the fairing 29 by the detection component, and then the moving component drives the detection component to measure the deviation of the straight line where the fairing 29 is located at the angle, so that there is no need to clamp multiple times, and the surface of the fairing 29 can be completely measured.

[0052] like Figure 1 As shown, in this embodiment, the clamping assembly includes: a first electric push rod 24 whose bottom end is fixed to the upper end of the base 1; a bearing plate 25 connected to the output end of the first electric push rod 24; a first fixed clamping plate 28 fixedly arranged on the upper end of the bearing plate 25; a second electric push rod 26 whose bottom end is connected to the bearing plate 25; a first movable clamping plate 27 connected to the output end of the second electric push rod 26, and a clamping area for clamping the fairing 29 is formed between the first movable clamping plate 27 and the first fixed clamping plate 28;

[0053] The above technical solution can be used to fix the fairing 29. The two ends of the fairing 29 are inserted into the clamping area between the first movable clamping plate 27 and the first fixed clamping plate 28. The second electric push rod 26 is started to push the first movable clamping plate 27 close to the first fixed clamping plate 28, so that the clamping area is continuously reduced until the two ends of the fairing 29 are clamped.

[0054] like Figure 3 As shown, in this embodiment, the detection component is a dial gauge 23, and the measuring rod of the dial gauge 23 contacts the surface of the fairing 29;

[0061] The above technical solution can be used to adjust the rotation angle of the dial indicator 23, so as to measure various parts of the surface of the fairing 29 and avoid the need for multiple clamping.
