[0002] The rotor refers to a rotating body supported by bearings. Objects such as optical discs that do not have their own rotating shafts can be regarded as a rotor when it uses a rigid connection or an additional shaft. After the rotor is processed and produced, it is often necessary to perform a vibration test on it;

[0003] However, when testing the rotor, the test device in the prior art can only detect the horizontal or vertical state of the rotor. However, due to the complex external environment, the rotor often works at an inclined angle, which leads to limitations in the test results of the rotor by the existing test device. Therefore, it is necessary to design an adaptive rotor vibration test device to solve the above problems. Utility Model Content

[0025] Specifically, a rotor 5 is provided at the top of the rotating rod 15, and a sliding sleeve 6 used in conjunction with the rotating rod 15 is fixedly installed at the bottom of the rotor 5. One side of the sliding sleeve 6 is slidably connected to the limit rod 7 by opening an opening. Both ends of the limit rod 7 are arc surfaces, and one end of the limit rod 7 passes through the rotating rod 15 and the sliding sleeve 6 and extends to the outside of the sliding sleeve 6. A hydraulic rod 8 is fixedly installed on the front side of the top of the base 1 through a bracket, and a push plate 9 is fixedly installed on the surface of the U-shaped plate 3. A trapezoidal plate 10 is fixedly installed below the surface of the push plate 9. A groove 11 used in conjunction with the hydraulic rod 8 is opened on the surface of the trapezoidal plate 10. By setting the hydraulic rod 8 and controlling the hydraulic rod 8 to extend, the hydraulic rod 8 extends and contacts with the push plate 9, so that the U-shaped plate 3 is tilted. After the U-shaped plate 3 is tilted, the rotor 5 is tilted, and after the hydraulic rod 8 is fully extended, the rotor 5 can be horizontally handled by the trapezoidal plate 10 and the groove 11. At this time, the effect of vibration testing the rotor 5 can be achieved by starting the motor 4, thereby achieving the effect of multi-angle vibration testing of the rotor 5.

[0026] Specifically, both sides of the inner cavity of the U-shaped plate 3 are provided with a slide groove 12, and a slider 13 is slidably connected inside the slide groove 12. A traction plate 14 is fixedly installed between the two sliders 13. A threaded sleeve 16 is fixedly installed on the left side of the top of the traction plate 14 through an opening. The internal thread of the threaded sleeve 16 is connected to a threaded rod 17. The bottom end of the threaded rod 17 is rotatably connected to the bottom of the inner cavity of the U-shaped plate 3 through a bearing. A limiting sleeve 18 used in conjunction with the limiting rod 7 is fixedly installed on the top of the traction plate 14. The inner wall of the limiting sleeve 18 is a smooth arc surface, which can be slidably connected to the two ends of the limiting rod 7. By setting the limiting sleeve 1 8, and by rotating the threaded rod 17, the threaded rod 17 rotates to drive the threaded sleeve 16 to rise, the rising of the threaded sleeve 16 drives the traction plate 14 to rise, the rising of the traction plate 14 drives the limit sleeve 18 to rise, the rising of the limit sleeve 18 can limit the limit rod 7, thereby achieving the effect of facilitating the installation and fixation of the rotor 5. After use, the threaded rod 17 can be rotated in the opposite direction to make the threaded rod 17 drive the traction plate 14 to descend, and the traction plate 14 descends and drives the limit sleeve 18 to descend. After the limit sleeve 18 descends, the limit rod 7 can be pulled out from the inner side of the sliding sleeve 6, thereby achieving the effect of facilitating the removal of the rotor 5.

[0027] Among them: both sides of the bottom of the traction plate 14 are fixedly installed with an insertion rod 19, the bottom end of the insertion rod 19 passes through the U-shaped plate 3 and extends to the outside of the U-shaped plate 3, and both sides of the top of the base 1 are fixedly installed with a sleeve 20 used in conjunction with the insertion rod 19. By setting the insertion rod 19 and the sleeve 20, the traction plate 14 can drive the insertion rod 19 to descend when it descends, and the insertion rod 19 can be inserted into the sleeve 20 after it descends, thereby achieving the effect of facilitating the limiting of the U-shaped plate 3 and avoiding the shaking of the U-shaped plate 3 during carrying or moving the device.

[0028] Working principle: The utility model is an adaptively adjustable rotor vibration test device. By rotating the threaded rod 17, the threaded rod 17 rotates to drive the threaded sleeve 16 to rise, the rising of the threaded sleeve 16 drives the traction plate 14 to rise, the rising of the traction plate 14 drives the limit sleeve 18 to rise, and the rising of the limit sleeve 18 can limit the limit rod 7, thereby achieving the effect of facilitating the installation and fixation of the rotor 5. After the rotor 5 is installed, by controlling the extension of the hydraulic rod 8, the hydraulic rod 8 extends and contacts with the push plate 9, so that the U-shaped plate 3 is tilted, and the U-shaped plate 3 is tilted. After the tilting of the U-shaped plate 3, the rotor 5 is tilted, and after the hydraulic rod 8 is fully extended, the rotor 5 can be handled in a horizontal state through the trapezoidal plate 10 and the groove 11. At this time, by starting The motor 4 can achieve the effect of performing a vibration test on the rotor 5, and thus achieve the effect of performing a multi-angle vibration test on the rotor 5, and the test result is more realistic. After use, the threaded rod 17 can be rotated in the opposite direction to cause the threaded rod 17 to drive the traction plate 14 to descend, and the traction plate 14 drives the limit sleeve 18 to descend after it descends. After the limit sleeve 18 descends, the limit rod 7 can be pulled out from the inner side of the sliding sleeve 6, thereby achieving the effect of facilitating the removal of the rotor 5, and the traction plate 14 descends and drives the insertion rod 19 to descend, and the insertion rod 19 can be inserted into the insertion sleeve 20 after it descends, thereby achieving the effect of facilitating the limiting of the U-shaped plate 3, and avoiding the shaking of the U-shaped plate 3 during carrying or moving the device.
