[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] like Figure 1 As shown;

[0034] A motor rotor dynamic balancing testing device includes a workbench 1 and an adjustment frame 4 disposed on the surface of the workbench 1, wherein a testing head 5 is mounted on the surface of the adjustment frame 4.

[0035] In this implementation plan: In the prior art, when using a dynamic balancing test device for a generator rotor, the operator first confirms the size of the rotor body by setting up a lifting mechanism, an adjusting mechanism, and a movable plate. After confirmation, the operator starts the adjusting motor, which drives the lead screw to rotate. The nut seat moves the movable plate back and forth due to the rotation direction of the lead screw. At the same time, the base on the front of the movable plate also moves, thereby adjusting the distance between the movable plate and the fixed plate. After adjustment, the operator places the rotor body in the center position of the top bearing of the movable plate and the fixed plate. Then, the operator places the transmission belt on the outside of the rotor body and sleeves it on the outside of the transmission wheel. If the transmission belt is too loose or too tight after installation, the operator starts the lifting rod, which drives the drive motor on the motor frame. The device moves up and down to adjust the tension of the transmission belt, allowing it to fix the rotor body according to testing requirements. Once fixed, the operator adjusts the adjustment frame so that the testing head contacts the rotor body. Then, the operator starts the drive motor, which drives the transmission wheel to rotate. The transmission belt on the transmission wheel then drives the rotor body to rotate, and the testing head then tests the rotor body. This improves the flexibility of the dynamic balancing test device, allowing it to be adjusted according to the size and length of the rotor and the rotating parts driving the rotor. Therefore, it also improves the testing effect of the dynamic balancing test device. For the specific working process, refer to "CN217765354U discloses a dynamic balancing test device for a generator rotor".
