Description

Technical Field

[0001] The present invention belongs to the technical field of non-destructive testing of aero-engines, and particularly relates to an auxiliary device for fluorescent penetrant testing of an integral bladed disk. Background Art

[0002] The integral bladed disk is a new type of structural part designed to meet the requirements of high-performance aero-engines. It can integrate the engine rotor blades and the disk, eliminating parts such as tenons, mortises, and locking devices in the connection between the disk and the blades. This can greatly reduce the number of parts and simplify the engine structure, thereby significantly improving the aerodynamic efficiency and being widely used in aero-engines. As an important rotating component of an aero-engine, the integral bladed disk operates in a harsh environment. Therefore, it is necessary to detect the integral bladed disk before use through fluorescent testing. Fluorescent testing, as an important means for detecting the surface quality of parts, has the advantage of high detection sensitivity and can effectively ensure the safe use of the integral bladed disk.

[0003] Since the existing fluorescent penetrant testing of integral bladed disks requires multiple steps such as penetration, emulsification, cleaning, drying, imaging, and inspection, the testing process is cumbersome and complex. Therefore, a tooling sling for loading the integral bladed disk is needed to cooperate with the integral bladed disk to complete the entire testing process on the fluorescent penetrant testing line. However, due to the complex structure, large volume, heavy weight, the fact that the disk body and blades are already machined, and the presence of numerous holes and cavities in the integral bladed disk, the following difficulties exist during the fluorescent penetrant testing process: Firstly, the structure of the integral bladed disk is complex, with numerous holes and cavities that are prone to accumulating excess fluorescent penetrant. When removing the excess penetrant from the integral bladed disk, it needs to be turned over for cleaning. However, it is heavy, not only large in volume but also difficult to turn over. Moreover, the disk body and blades are already machined, so special attention needs to be paid to the protection of the blades, resulting in operational difficulties. Secondly, in order to ensure the cleaning effect, a rotating table needs to be equipped in the automatic cleaning tank of the penetrant testing line. When the rotating table starts and stops, the integral bladed disk may slide, posing a risk of scratching the blades of the integral bladed disk and making it inconvenient for the cleaning and testing of the integral bladed disk. Finally, when using a conventional part frame to operate on the testing line, the integral bladed disk may slide, posing a risk of scratching the blades of the integral bladed disk, and a corresponding fixing structure is needed to avoid this risk. Therefore, there is an urgent need for an auxiliary device for fluorescent penetrant testing of integral bladed disks to solve the above problems. Summary of the Invention

[0004] In view of this, the present invention provides an auxiliary device for the fluorescence penetrant inspection of integral bladed disks, which is applied to the field of non-destructive testing technology for aero-engines. It mainly aims at the transfer and cleaning processes in the fluorescence penetrant inspection of integral bladed disks, and solves the technical problems of the existing integral bladed disks having many holes, difficult cleaning of redundant penetrant liquid in cavities, low detection efficiency, easy collision and scratching of parts, and poor operability of fluorescence penetrant inspection.

A horizontally extending transverse extension rod is arranged on the cross beam. The connecting base includes a fixed block and a fixed shaft. The fixed block is sleeved on the transverse extension rod. The fixed shaft is fixedly connected to the horizontal side surface of the fixed block by welding. The bushings are on the corresponding fixed shafts. The integral blisk on the bushings is supported by the fixed shafts, thereby preventing the integral blisk from sliding horizontally under the support of the cross beam. End caps are arranged at the horizontal two ends of the transverse extension rod. The end caps are located inside the corresponding clamping grooves, and the transverse extension rod and the clamping grooves are connected through the end caps.
