[0027] Please refer to Figure 1 and Figure 4 The downward sliding guide mechanism 6 comprises a pull rod 64, a collecting frame 61 is fixedly connected to one side of the workbench 1, a guide groove 62 is hollowed out in the top end of the workbench 1, an electric push rod 63 is fixedly connected inside the workbench 1, the output end of the electric push rod 63 is fixedly connected with the support 2, the pull rod 64 is hingedly connected to the two sides of the support 2, one end of the two pull rods 64 is hingedly connected with a guide block 65, the guide block 65 is slidingly connected with the top end of the workbench 1, the guide groove 62 and the collecting frame 61 are communicated, and the guide block 65 is designed in a triangular shape, and the inclined surface of the guide block 65 faces upward, and is used for guiding the magnetic particle suspension.

[0028] The working principle of the generator rotor measurement structure is as follows:

[0029] Firstly, the user places the generator rotor to be measured on the support 2; the support 2 is installed inside the workbench 1 and is provided with the electric push rod 63, so that the support 2 can realize the lifting function; when the measurement is ready to start, the electric push rod 63 is started to lift the support 2 together with the generator rotor thereon to a predetermined working position;

[0030] Once the generator rotor reaches the predetermined position, the medium servo motor 58 is started to drive the threaded rod 57 to start rotating; since the threaded rod 57 is designed in a bidirectional thread, the two hollow sleeves 4 can move symmetrically on the threaded rod 57; in this way, the two ends of the rotor on the support 2 can be butted against the two hollow sleeves 4, and at the same time, the electromagnet 3 is ensured to be in close contact with the two ends of the rotor;

[0031] Next, the gas pump 55 starts to work to make the ring-shaped air bag 54 expand; the expansion of the ring-shaped air bag 54 firmly fixes the generator rotor inside the two hollow sleeves 4, so as to ensure that the rotor will not move in the subsequent detection process;

[0032] Subsequently, the electric push rod 63 works again, driving the bracket 2 to descend; as the bracket 2 descends, the pull rod 64 symmetrically hinged on both sides of the bracket 2 also starts to move; one end of the pull rod 64 is hinged with a guide block 65, which moves towards the bracket 2 along with the movement of the pull rod 64, and finally blocks the movable groove on the bracket 2;

[0033] At this time, the user can pour the magnetic particle suspension on the part of the generator rotor that needs to be measured; the magnetic particles in the magnetic particle suspension will be attracted and attached to the damage on the surface of the rotor; after standing for a period of time, the rotor is irradiated by the ultraviolet lamp 7; the irradiation of the ultraviolet lamp 7 will make the magnetic particles emit fluorescence, so that whether the generator rotor has damage can be detected non-destructively;

[0034] When it is necessary to replace the detection surface, the user only needs to start the small servo motor 53; the small servo motor 53 drives the worm 52 to rotate, and in turn drives the hollow worm gear 51 to rotate; since the hollow worm gear 51 is fixedly connected with the generator rotor, the rotor will also rotate, realizing replacement of the detection surface;

[0035] In addition, the design of the fixed turnover mechanism 5 not only ensures the stability of the generator rotor during the measurement process, but also through the inflation and deflation of the annular air bag 54 by the air pump 55 and the spring tube 56, the rotor can be conveniently fixed and released, facilitating the turnover operation to adapt to the measurement requirements of different angles;

[0036] During the entire measurement process, the downward sliding guide mechanism 6 plays a key role; when the bracket 2 descends, the cooperation of the pull rod 64 and the guide block 65 enables the magnetic particle suspension to be guided and collected into the collection frame 61, preventing the scattering and waste of the measurement liquid, and maintaining the neatness of the workbench;

[0037] Through this design, the entire generator rotor measurement structure can efficiently and accurately complete the damage detection of the generator rotor, improving the detection efficiency and accuracy.
