AI Technical Summary
Technical Problem
Existing maintenance methods for aircraft thrust reversers are difficult to control in terms of accuracy and coaxiality, and are costly and time-consuming.
Method used
Design a maintenance fixture for aircraft thrust reversers, comprising two clamping parts, fasteners, and a hinge assembly. By ensuring the coaxiality of the clamping parts and the progressive reaming of the hinge assembly, the reaming accuracy and coaxiality of the lug holes are ensured. Combined with the installation of the protective layer and bushing, efficient maintenance is achieved.
Benefits of technology
This effectively ensures the accuracy and coaxiality of the reaming hole, reduces maintenance costs, shortens the maintenance cycle, and avoids the need to replace the entire slide rail beam.

Abstract
本申请实施例提供了一种用于飞机反推装置的维修工装及维修方法，维修工装包括两个夹紧件、紧固件和铰修组件，两个夹紧件间隔设置的两个夹紧件之间用于收容两个接耳，每一夹紧件具有维修开口，两个夹紧件的维修开口同轴设置。紧固件分别与两个夹紧件连接，以使两个夹紧件夹紧两个接耳。铰修组件至少部分能够伸入维修开口以与接耳孔接触。本申请提供的维修工装，通过两个夹紧件实现两个接耳的固定夹紧，同时由于两个维修开口同轴设置，在对接耳孔进行维修操作时，能够有效保证两个接耳孔的铰孔精度和同轴度，且能够同时对两个接耳进行维修处理，降低维修成本，缩短维修周期。
