Description

Technical Field

[0001] The utility model relates to the technical field of wing joint positioning tools, in particular to a universal tool for checking the positioning of wing joints. Background Art

[0002] The precise docking of key components such as aircraft wings, ailerons and flaps is an important part of ensuring the flight performance and safety of the aircraft. The docking of these components requires precise joints, and the selection and design of the joint position are directly related to the assembly quality and overall performance of the aircraft components. Therefore, the joint position is regarded as a key and important feature of aircraft components, and any slight deviation may lead to serious consequences.

[0003] In the aircraft assembly process, the assembly jig plays a vital role. Its main task is to ensure the position accuracy of the aircraft component joints so that the components can be accurately and firmly docked together. However, in daily practical assembly, the jig position sometimes exceeds the tolerance, which directly leads to the position of the aircraft joint exceeding the tolerance, thus causing a series of quality problems.

[0004] In order to solve this problem, laser trackers are currently used as a means of detection and verification. With its high precision and high efficiency, laser trackers have become an important tool for detecting whether the position of jigs and fixtures is out of tolerance. However, relying solely on laser trackers cannot completely solve all problems. In actual operation, laser trackers are relatively expensive, resulting in fewer devices and difficult coordination.
