Description

A simulation device for detecting damage in aero-engine blades Technical Field

[0001] This utility model relates to the field of borehole simulation technology, and in particular to a borehole simulation device for aero-engine blade damage. Background Technology

[0002] Borehole inspection of aero-engine blades is a crucial non-destructive testing technique in aero-engine maintenance. This technique allows for visual inspection of critical components like blades by inserting an endoscope probe into the engine through pre-drilled observation holes or specialized perforations, without disassembling the engine. This avoids secondary damage that can occur during engine disassembly and reassembly, reducing maintenance costs and risks. Specialized borehole inspection simulation devices are essential for the routine study and analysis of aero-engine blade damage borehole inspection techniques, facilitating more intuitive simulation operations for technicians.

[0003] Previous aero-engine blade damage borehole inspection simulation devices have the following drawbacks: 1. They are inconvenient for simulating borehole inspection procedures and understanding precautions, hinder the training of inspection personnel's proficiency, and prevent the aero-engine model on top of the inspection platform from being rotated to different positions for convenient borehole inspection simulation operations. Therefore, those skilled in the art have provided an aero-engine blade damage borehole inspection simulation device to solve the problems mentioned in the background art. Summary of the Invention

[0004] The main objective of this invention is to provide a device for simulating borehole damage in aero-engine blades, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hole detection simulation device for aero-engine blade damage includes a base, a detection table, and a hole detector body;

[0007] A servo motor is mounted on one top end of the base via a mounting bracket. The output shaft of the servo motor is connected to a rotating shaft via a coupling, and the top of the rotating shaft is connected to a detection platform via a connecting plate. A T-shaped support plate is bolted to the other top end of the base. An L-shaped base plate is mounted on the top of the T-shaped support plate via an L-shaped support foot. A borescope body is mounted on the top of the horizontal plate of the L-shaped base plate via screws. A sealing cover is connected to the top of the vertical plate of the L-shaped base plate via a damping shaft. A rubber limiting sleeve is adhered to one side of the top of the T-shaped support plate, and a grip rod is fitted inside the rubber limiting sleeve. A pinhole camera is connected to one end of the grip rod via an elastic metal rod.

[0008] As a further improvement of this utility model: a servo motor controller is installed on the top of the base and at one end of the servo motor by screws. The output end of the servo motor controller and the input end of the servo motor are electrically connected by wires. The servo motor controller facilitates the control of the rotation angle of the servo motor, thereby rotating the aircraft engine model on the top of the testing platform to different positions.

[0009] As a further improvement of this utility model, a U-shaped support frame is bolted to the top of the base and above the servo motor.

[0010] As a further improvement of this utility model: a stabilizing bushing is fixedly fitted onto the U-shaped support frame, and the rotating shaft passes through the stabilizing bushing.

[0011] As a further improvement of this utility model, one side of the L-shaped base plate is provided with a power cable hole for easy passage of the power cable of the borehole probe body.

[0012] As a further improvement of this utility model: the input end of the borescope body is connected to the output end of the pinhole camera via a wire, and the wire passes through the handle and the elastic metal rod. The pinhole camera is inserted into the engine model by holding the handle, and the borescope body is used to perform visual simulation inspection of key components such as blades.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Place the aircraft engine model on top of the inspection platform. Through the reserved observation hole or special small hole, remove the handle inside the rubber limiting sleeve. Hold the handle and insert the pinhole camera into the engine model. Use the borescope body to perform a visual simulation inspection of key components such as blades. This avoids secondary damage that may be caused by disassembling and reassembling the engine, reduces maintenance costs and risks, simulates borescope inspection procedures, and helps to understand precautions, which is conducive to improving the proficiency of inspection personnel.

[0015] 2. The servo motor controller facilitates the control of the servo motor's rotation angle, thereby rotating the aircraft engine model on top of the testing platform to different positions for easy borehole exploration simulation. The U-shaped support frame and stabilizing bushing improve stability during rotation and reduce shaking of the rotating shaft. After the borehole exploration simulation is completed, the sealing cover is snapped onto the top of the borehole probe body, effectively providing dust and water protection and ensuring safe storage.
