[0003] Authorization announcement number CN220525270U discloses a stator blade vibration fatigue test fixture. This patented technology divides one end of the clamping block into several clamping blocks through an adjustment groove, so that the clamping block has good elastic deformation ability, and the inner side of the clamping block is a part of the side wall of the clamping through hole. The clamping block has a large contact area with the rotating shaft of the stator blade, so that the clamping block can stably clamp the stator blade and ensure the test effect; however, in this scheme, when clamping the stator blade, manual clamping is required.

In addition, the use angle of the clamp cannot be adjusted, thereby reducing the accuracy of clamping and detection.

The output end of the telescopic rod 302 is fixedly connected to a first clamping block 303, and the side of the supporting plate 301 is fixedly connected to a second clamping block 304. A stator blade body 305 is arranged between the first clamping block 303 and the second clamping block 304. The fixed plate 203 is driven by the rotary motor 202 to rotate the clamp mechanism, which can increase the accuracy of clamping the stator blade body 305, thereby improving the accuracy of clamping detection. The rotation of the clamp mechanism can expand the types of stator blade bodies 305 to be detected, increase the detection range, and further improve the flexibility of the stator blade vibration fatigue test fixture when in use.

[0028] Among them, the fixed plate 203 is fixedly connected to the supporting plate 301, and the top of the base frame 101 is fixedly connected to a supporting bracket 306. There are two supporting brackets 306. The top of the supporting bracket 306 is fixedly connected to a top frame 307. The top of the top frame 307 is fixedly connected to a protective shell 308. The stator blade body 305 is arranged inside the protective shell 308.

[0029] In this embodiment, reference Figure 1 and Figure 4 As shown, the automatic displacement component 4 includes a supporting plate 401, a motor 402 is installed on the side of the supporting plate 401, the output end of the motor 402 is fixedly connected to a threaded rod 403, the side of the threaded rod 403 is threadedly connected to a threaded block 404, the side of the supporting plate 401 is fixedly connected to a sliding rod 406, the side of the sliding rod 406 is slidably connected to a slider 407, the top of the threaded block 404 and the slider 407 is fixedly connected to a connecting plate 408, there are two sliding rods 406, two supporting plates 401, and four sliders 407, the side of the supporting plate 401 is fixedly connected to a bearing seat 405, the threaded rod 403 extends to the inside of the bearing seat 405, the motor 402 is used to drive the threaded rod 403 to rotate and cooperate with the sliding rod 406 and the slider 407 to move the clamping component 3 on the top of the connecting plate 408, thereby increasing the intelligence and automation of the equipment.
