Low-stress conductive sealing adjustment device and method for aviation light window

Abstract

The invention relates to a low-stress conductive sealing adjustment device and method for an aviation light window. By using instruments and equipment such as a height indicator, a precise electric control adjustment table and an auto-collimation light pipe, special process equipment such as a light window adjustment reference tool and a light window supporting tool and a composite bonding layer,the adjustment reference of the aviation light window can be quickly established, the adjustment precision is improved, the clamping stress and the bonding stress are reduced, the adjustment stress isavoided, the optical performance is ensured while the sealing performance and the electromagnetic shielding performance of the aviation light window are ensured, and the adjustment efficiency and theadjustment quality of the aviation light window are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of optical-mechanical assembly and adjustment, and relates to a low-stress conductive sealing assembly and adjustment of aviation optical windows, which can quickly establish an assembly and adjustment reference, improve the accuracy of assembly and adjustment, and avoid assembly and adjustment stress, and can ensure the sealing performance of aviation optical windows, Electromagnetic shielding performance while ensuring optical performance. Background technique [0002] The aviation optical window is the optical window of the airborne photoelectric detection system. The quality of its installation and adjustment directly determines the optical performance, sealing performance and electromagnetic shielding performance of the system. Due to the particularity of its structure, there is no direct assembly and adjustment reference during the assembly and adjustment process, which is easy to introduce large clamp...

AI Technical Summary

Problems solved by technology

Due to the particularity of its structure, there is no direct assembly and adjustment reference in the assembly and adjustment process, which is easy to introduce large clamping stress and bonding stress, and it is difficult to ensure optical accuracy, sealing requirements and electromagnetic shielding requirements at the same time

Aviation optical windows generally provide assembly and adjustment references through fixed face-to-face cooperation, and use plugs and pressure plates to restrict the degree of freedom of assembly and adjustment. The stress of assembly and adjustment is large, resulting in a decrease in optical performance, and it is difficult to ensure sealing performance and electromagnetic shielding performance at the same time
