Embodiment 1

[0030] This embodiment discloses a special gap detection tool for aircraft. As a basic embodiment of the present invention, it includes a handle 1 and a detection elbow 2. The handle 1 and the detection elbow 2 are detachably connected. The connection structure can facilitate quick installation 1. Disassemble or replace the detection elbow 2. Different areas on the aircraft may have different requirements for the minimum gap, that is, the required outer diameter d of the detection elbow 2 is different. Based on the perspective of saving materials and storage space, this technical solution can realize a The handle 1 is equipped with a plurality of detection elbows 2 of different types (that is, with different outer diameters d), which further makes this technical solution applicable to many areas of the aircraft that require different clearances, and expands the scope of application of this technical solution.

Embodiment 2

[0032] This embodiment discloses a special gap detection tool for aircraft. As a preferred embodiment of the present invention, that is, in Embodiment 1, the handle 1 is screwed to the detection elbow 2, and further, the handle 1 is provided with a connection Seat 3, the detection elbow 2 is provided with a connector 4, or the detection elbow 2 is provided with a connector 3, and the handle 1 is provided with a connector 4; the center of the connector 3 is provided with a spiral groove 5, and the connector 4 is provided with Corresponding to the spiral groove 5 is an external helical structure 6; the handle 1 is a telescopic rod structure; the detection elbow 2 includes a metal strip 2.1 made of alloy material and a protective layer 2.2 wrapped outside the metal strip 2.1, The protective layer 2.2 is made of plastic material or rubber material.

[0033] In this technical solution, the connection between the connecting elbow and the handle 1 is connected by a spiral structure, ...

Embodiment 3

[0035] This embodiment discloses a method of using a gap detection tool, as a basic implementation of the present invention, including gap qualified detection, the detection tool includes a handle 1 and a detection elbow 2, and the handle 1 and the detection elbow 2 Detachable connection; hold the handle 1 and extend the detection elbow 2 into the gap. If the detection elbow 2 cannot be smoothly inserted into the gap, it indicates that the gap width is unqualified. If the detection probe can enter the gap smoothly, the detection bend The head 2 moves along the extending direction of the gap. If the movement is smooth, it indicates that the gap is qualified, otherwise, it indicates that the gap is unqualified.

[0036] The technical solution discloses the principle and specific implementation of gap detection by using a gap detection tool. The implementation is fast and effective, and the detection result is effective and reliable.

Abstract

The invention relates to the technical field of gap detection on aircrafts, in particular to a gap detection tool special for airplanes and a using method. The gap detection tool comprises a handle and a detection elbow, the handle is detachably connected with the detection elbow, the detection elbow extends into a gap, and if the detection elbow cannot smoothly extend into the gap, is it indicated that the gap width is unqualified; and if the detection probe can smoothly enter the gap, the detection elbow moves along the gap extension direction, and if the detection elbow moves smoothly, it is indicated that the gap is qualified, and otherwise, it is indicated that the gap is unqualified. According to the technical scheme, the gap detection tool special for the airplane is provided for gap detection in all areas of the airplane, the structure is simple, the cost is low, the narrow and complex space gap detection which cannot be achieved through detection means, such as optics, calipers, etc., can be achieved, and the technical scheme is convenient and fast to implement. The rapid detection of gaps can be realized after airplane conduits and cables are installed, the reliability ofdetection results can be ensured, and meanwhile, the high detection efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of gap detection on aircraft, in particular to a special gap detection tool for aircraft and a use method. Background technique [0002] In the aviation industry, after the installation of aircraft ducts and cables, there is a requirement for a minimum gap between the ducts and the ducts, and between the ducts and the cables. That is, if the gap is too small or there is no gap, the ducts, cables may be Grinding with the surrounding parts will further cause the conduit to wear and cause oil leakage, as well as the cable to wear and tear, which is very likely to further cause unpredictable consequences. Therefore, the clearance of conduits and cables needs to meet the lower limit value given by the design to ensure the safety of the aircraft during flight tests and in-service flights. [0003] Conduits and cables are installed in the interior of each compartment of the aircraft, such as landing gear compartme...
