Abstract
Description
Technical Field
[0001] This invention relates to the field of assembly position detection technology for aerospace product components, specifically to a detection device for positional defects in aircraft assembly components. This method and device can quickly detect the accuracy of component assembly positions, avoiding the influence of human factors. Background Technology
[0002] With the development of aviation technology, the positional accuracy requirements for the assembly of aviation product components are becoming increasingly stringent. However, during actual assembly, due to the inherent tolerances of the parts, positioning deviations, and manufacturing deviations of the tooling fixtures, the assembled components may deviate from their theoretical positions, affecting the aircraft's strength, shape, and overall performance. Therefore, the detection of the correct assembly position of components in aviation products is becoming increasingly important. Currently, in actual production, the detection of component positions mainly relies on tooling locators and shape clamps. The correctness of the installation position is determined by measuring the relative relationship between the product and the locator / clamp. This process is cumbersome, labor-intensive, and heavily dependent on the experience of process designers, workers, and inspectors. Factors such as the accuracy of the tooling locators and clamps, the selection of measurement points, changes in workers and inspectors, and deformation of the locators and clamps due to long-term use are unavoidable. These factors lead to incomplete detection, insufficient reliability, and low accuracy. Therefore, to facilitate operators and inspectors in quickly detecting the assembly position of components while ensuring accurate and reliable results, a digital and intelligent method and device for detecting component assembly positions is urgently needed. Summary of the Invention
[0003] The present invention provides a detection device for detecting the relative position of aircraft components after assembly, for detecting defects in the assembly position of aircraft components, so as to solve the problems in the above-mentioned technical background.
[0004] The technical problem solved by this invention is achieved by the following technical solution:
[0005] This invention designs a device for detecting positional defects in aircraft assembly components. Using this device, operators and inspectors can be replaced to detect relative positional defects in aircraft components after assembly. By using deep learning technology to replace traditional manual inspection, the influence of human factors can be avoided and efficiency can be improved.
[0006] This invention employs a deep learning data acquisition module to collect and record the position information of the assembly to be inspected, and automatically transmits this information to a position calculation module. The position calculation module analyzes and processes the data, then feeds the results back to a microcontroller module. The microcontroller module processes the data and sends commands to a controller. The microcontroller and controller then display the inspection results on a screen for intuitive visualization (e.g., green for a successful inspection, red for a failed inspection). This allows the operator to quickly obtain the results. Simultaneously, if an inspection fails, an automatic buzzer and alarm light provide corresponding indications (the buzzer sounds and the alarm light flashes) for multi-directional alerts.

For complex assemblies, only a few positions can be checked, resulting in arbitrary and incomplete inspection results. The inspection relies heavily on human experience, lacks versatility, and is not accurate enough, leading to incomplete detection, low detection efficiency, and wasting time and effort.
[0059] To address the aforementioned issues, a simple and easy-to-operate method is needed for the detection of assembly positions of components. This method should be highly efficient and comprehensive, unaffected by the process design level of the process engineers or the skill level of the operators, and should provide clearer, more accurate, and faster results. This technical solution aims to provide operators with an adaptive assembly position detection device for components. Composed of mechanical and electrical control components, this solution features a simple structure, low cost, small size, portability, easy operation, and strong versatility, unaffected by the shape or size of the components. Its ingenious design enables precise detection. For various complex components, it allows for distance adjustments to meet different detection needs, demonstrating strong adaptability and high versatility. Multiple detection modules are used for automated intelligent detection, and the results are displayed using buzzers and warning lights. The results can also be directly output to a display screen, achieving efficient and intuitive detection.
[0060] During the assembly position inspection process, the implementation of the above-mentioned assembly position detection method improves the efficiency of assembly position detection, reduces complex manual operations, enhances operator comfort, boosts the confidence of inspectors in judging the correctness of assembly positions, and prevents products with undetected errors from entering the next stage of work due to various oversights. It enables rapid identification of the correctness of assembly positions, facilitates quick identification of poorly positioned assemblies, and allows for rapid troubleshooting, ensuring the stable and reliable position of the entire component assembly, meeting design requirements, and thus guaranteeing the realization of overall aircraft performance. This contributes to improved assembly accuracy and efficiency. Attached Figure Description
