Fluorescent penetrant detection device for aero-engine blade and use method

Abstract

The invention discloses an aero-engine blade fluorescent penetrant detection device and a use method, and belongs to the technical field of aero-engine blade detection. The aero-engine blade fluorescent penetrant detection device comprises a mounting shell, and the inner wall of the mounting shell is rotationally connected with a fixed cylinder; in the detection process, the suction nozzle is used for sucking and fixing the airspace engine blade, on one hand, the arc-shaped engine blade can be sucked and fixed, the situation that the detection is affected due to the fact that the engine blade shakes in the detection process is avoided, and on the other hand, clamping of a clamping piece on the engine blade is avoided, so that the detection efficiency is improved. The whole surface of the engine blade can be completely detected, the situation that the edge of the engine blade is blocked due to the fact that a clamping piece is used, complete detection cannot be conducted, and the quality of the produced engine blade is affected is avoided, the engine is automatically overturned and fixed through butt joint of installation grooves in a fixing cylinder and a switching cylinder, manual disassembly and assembly are not needed, and the production efficiency is improved. The workload of workers can be reduced, and the damage to the engine blade during disassembly and assembly can be reduced.

Description

technical field [0001] The invention relates to the technical field of aero-engine blade detection, in particular to a fluorescent penetration detection device for an aero-engine blade and a method for using the same. Background technique [0002] In the manufacturing industry, defects such as small cracks on the surface of raw materials and parts that are difficult to see with the naked eye often make product quality unable to meet customer requirements. To detect these surface defects, fluorescent penetrant detection technology is widely used in the industry. Dry developing powder is applied to the surface of the workpiece to be inspected. Under the action of capillary, the penetrant in the crack is adsorbed to the surface of the workpiece to be inspected, and then the defect inspection is carried out under a black light. [0003] In the prior art, when the fluorescent penetration method is used to detect the aero-engine blade, because the aero-engine blade is arc-shaped ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of fluorescence penetrating detection device of aero-engine blade and using method, to solve the above-mentioned background technology. And it is relatively thin. When it is placed on the platform for detection, the aero-engine blade will shake, which will affect the normal detection. During clamping detection, the clamping part usually covers the edge part of the surface of the aero-engine blade, resulting in the edge part not being detected. Therefore, during detection, Usually, manual inspection is required, which increases the amount of manual labor, and both sides of the aero-engine blade need to be inspected. When manually inspecting many aero-engine blades at one time, it is easy to confuse, resulting in missed inspections or repeated inspections.
