Aircraft engine blade nondestructive flaw detection device

Abstract

The invention discloses an aircraft engine blade nondestructive flaw detection device, and particularly relates to the field of aircraft engine blades, the aircraft engine blade nondestructive flaw detection device comprises a cleaning mechanism and a detection mechanism, the cleaning mechanism comprises an air bag telescopic rod, a push rod frame is inserted into the top end of the air bag telescopic rod, and a fixed clamping block frame is clamped to one side of the push rod frame; a plurality of groups of movable cleaning brush plates are arranged on the surface of the fixed clamping block frame, mounting holes for insertion are formed in the centers of the inner sides of the movable cleaning brush plates, and deflection rods are clamped to the two sides of the movable cleaning brush plates. And the other side of the cleaning movable brush plate moves towards the outer side by cleaning the limit on the inner side of the cleaning movable brush plate, so that the cleaning movable brush plate is attached to the concave part of the machine sheet, and the surface of the machine sheet is fully washed, so that the influence of impurities on later detection is avoided while workers are replaced to clean the surface of the machine sheet by themselves.

Description

technical field [0001] The invention relates to the field of aircraft engine blades, and more specifically, the invention relates to a non-destructive testing device for aircraft engine blades. Background technique [0002] An aircraft engine is a highly complex and sophisticated thermodynamic mechanism that provides the aircraft with the power required for flight. As the heart of an aircraft, it is known as the "Flower of Industry". It directly affects the performance, reliability and economy of an aircraft. It is an important manifestation of a country's technology, industry and national defense strength. The characteristic of engine research and development is technical difficulty. Large, costly, and long-term, the engine has a decisive impact on the performance of the aircraft and the success or failure and progress of aircraft development, and the engine technology has good dual-use characteristics for military and civilian use, which is of great significance to nationa...

Problems solved by technology

[0003] However, when the current aircraft engine blades are in use, the surface will be hindered by wind force, and there will be deep scratches on the surface, while the commonly used non-destructive testing devices can only detect large scratches or depressions on aircraft engine blades. The details cannot be detected, and the overall work efficiency is low. Therefore, we propose a non-destructive testing device for aircraft engine blades
