Description

Background
An Intake housing, sometimes referred to as an Intake duct or tube, is an important component of an aircraft engine that helps to efficiently direct air to the compressor or turbofan inside the engine. It is designed in a specific shape, usually cylindrical or funnel-shaped, in order to maximize air inflow efficiency and reduce aerodynamic resistance to the engine.
During test runs and service of an aeroengine, there is a need to replace the intake casing, for example:
1. during aeroengine bench testing, an excessive amount of engine fan rotor imbalance may occur, resulting in vibration of the entire engine exceeding the limit. In order to solve the problem, the air inlet casing needs to be disassembled, and the balancing weight arranged at the front end of the engine fan rotor-stator assembly is correspondingly adjusted so as to optimize the unbalance amount and reduce vibration.
2. The fixed support plate of the air inlet casing is usually processed by using a TC4 plate superplastic forming and integral welding process. However, in the actual use process, the support plate is easy to have matrix crack faults due to the influence of complex factors such as airflow, mechanical excitation and the like, so that the use safety of the engine is influenced.
3. During take-off and landing, the engine may cause damage to the blades due to ingestion of birds or foreign objects. In this case, it is necessary to perform the separation and replacement of the intake casing in time. Particularly during war, in-situ replacement of an air intake casing by an aircraft on a battlefield is of great importance to ensure maintenance and attendance of equipment.
In the prior art, the separation technology of the air inlet casing mainly relies on a conventional rotary ball screw to horizontally separate the air inlet casing from the fan rotor-stator assembly. For example, chinese patent application No. CN202010641531.4 discloses an air inlet casing disassembly tool, which includes: a brace rod; one end of the screw rod of the ball screw assembly is connected with the stay bar and is L-shaped; the screw nut of the ball screw assembly is screwed on the screw; the outer ring of the ball screw assembly is sleeved on the screw nut; the screw nut rotates on the screw rod to drive the outer ring to axially translate along the screw rod. The disassembly tool for the air inlet casing disclosed by the patent adopts a rotary ball screw to horizontally separate the air inlet casing from a fan rotor-stator assembly. However, this technique has the following problems:
1. the operation strength and speed are not easy to control, and the seam allowance between the cases can be damaged, so that the operation is forced to be interrupted.
2. The displacement of the horizontal separation has uncertainty and may settle after release of the bearing play, resulting in direct impact to the graphite ring and damage.
3. The traditional operation process lacks data recording and outputting, so that the operation quality is difficult to measure and transfer and cannot be effectively distinguished.
4. The operation efficiency is low, and a plurality of persons are required to cooperatively train and complete the work on site, which is disadvantageous for the field repair and maintenance work.
