Description
Technical Field

In addition, the invention also relates to a method for detecting the excess in the casting case of the aero-engine by adopting the device for detecting the excess in the casting case of the aero-engine.
Background
The aeroengine casing is an important part for supporting a stator system and a rotor system of the aeroengine and is a base of the whole aeroengine. Meanwhile, the casing also plays a role in transmitting thrust generated by the engine to the airplane, is a main bearing part of the aircraft engine, and plays a significant role in the design, research and development and safe operation of the whole aircraft engine.
The casings are generally cast by a die-casting method because the casings have various shapes and complex structures due to the influence of differences of the types of aero-engines, the functions of the casings, the working environments and the working positions of the casings and the like. However, due to the complicated structure of the casing cavity and the poor flowability of the molding sand, if the molding sand is not completely melted and flows out of the cavity after the casing is cast, a residual excess is formed in the cavity. In the casting process, a part of excess matters such as a batch front and burrs are formed in the cavity of the casing. In the process of pouring steel balls into the casting box and polishing the steel balls, due to the fact that the inner structure of the casing is complex, the situation that the steel balls cannot be poured out completely is prone to occurring, and therefore surplus objects are formed. If the excess is not detected in time, the air flow in the casing may be affected when the engine blade rotates at a high speed, and even the excess may be thrown into an engine rotor when the engine works, which poses a serious threat to the safety work of the engine.
The existing device and method for detecting the excess materials in the casting case of the aircraft engine generally adopt a film photographic method, but the film photographic method often has the following problems in the actual use process: 1. because the film needs to be attached and taken frequently in the shooting process of the film photography method, the operation process is complex, in order to ensure the definition and the resolution of the pictures, only one picture can be attached at each angle for shooting, the next picture is shot after the film is washed out, the workload is large, and most of the pictures are repeated mechanically, the detection efficiency is extremely low, and the shooting period is long; 2. when the film photography method is used for shooting and imaging, the obtained film is a projection of an object to be detected on the film by taking an X-ray tube head as a point light source, and the depth information of the redundancy is ignored in the projection process, so that the spatial position of the redundancy cannot be accurately positioned, the detection accuracy is low, and the clearing efficiency of the redundancy is low.
