[0014] Reference Figures 1 to 5 A stator and rotor detection device embodiment of the utility model is further described.

[0015] A stator and rotor detection device comprises a fixed base 1, a first rotating block 2 and a second rotating block 3. The fixed base 1 can be fixed to a body of the detection device by bolts. The first rotating block 2 and the second rotating block 3 can be respectively placed on opposite sides of the fixed base 1 and are both hinged to the fixed base 1, so that the first rotating block 2 and the second rotating block 3 are fixed to the fixed base 1 and can both rotate relative to the fixed base 1. An annular groove for placing the stator and rotor can be opened at the upper end of the fixed base 1. When the stator and rotor are placed in the annular groove of the fixed base 1, the first rotating block 2 and the second rotating block 3 can be rotated at the same time so that the first rotating block 2 and the second rotating block 3 are both pressed on the stator and rotor.

[0016] The first rotating block 2 is provided with a stop block 4, and the stop block 4 can be welded and fixed on the side wall of the first rotating block opposite to the second rotating block 3. The second rotating block 3 is provided with a stop cavity 5, and the opening of the stop cavity 5 can be placed on the side wall of the second rotating block opposite to the first rotating block 2, so that when the first rotating block 2 and the second rotating block 3 rotate towards each other, the stop block 4 on the first rotating block 2 can extend into the stop cavity 5 through the opening of the stop cavity 5 on the second rotating block 3. The second rotating block 3 is provided with a limiting member 6 and a limiting cavity 7 matched with the limiting member 6. The limiting cavity 7 can be connected with the stop cavity 5. The opening of the limiting cavity 7 can be placed on the top wall of the second rotating block 3 or on the side wall opposite to the first rotating block 2, so that the limiting member 6 can be extended into the limiting cavity 7 to operate.

[0017] The limiting member 6 includes a stop rack 8, a rotating screw 9, a rotating gear 10 and a sliding rack 11. The stop rack 8 is placed in the limiting cavity 7 and slides, and can slide from the limiting cavity 7 into the stop cavity 5. When the stop block 4 is fully inserted into the stop cavity 5, a slot 12 is opened at the stop block 4 corresponding to the position where the stop rack 8 is inserted, so that the stop rack 8 inserted into the stop cavity 5 can be directly inserted into the slot 12, so that the stop rack 8 is engaged with the stop block 4, that is, the first rotating block 2 is fixed relative to the second rotating block 3, so that the stator and rotor are stably fixed on the detection device for detection. The two ends of the rotating screw 9 can be fixed on the inner side wall of the limiting cavity 7 and rotatably connected with the second rotating block 3, so that the rotating screw 9 can be placed in the limiting cavity 7 and rotated. The thread on the rotating screw 9 can mesh with the gear teeth on the stop rack 8. When the rotating screw 9 rotates, it can drive the stop rack 8 to slide and extend. The gear 10 is inserted into the stop cavity 5 or slides back into the limit cavity 7. The rotating gear 10 is sleeved on the rotating screw 9 and the inner wall of the rotating gear 10 can be welded and fixed to the outer wall of the rotating screw 9, so that the rotating gear 10 and the rotating screw 9 can make the same rotation. The sliding rack 11 is placed in the limit cavity 7 and slides and extends to the opening of the limit cavity 7, so that the opening of the limit cavity 7 can be manually extended into the limit cavity 7 and the sliding rack 11 can be pushed to slide. The gear teeth on the sliding rack 11 can be meshed with the gear teeth on the rotating gear 10. The sliding of the sliding rack 11 can drive the rotating gear 10 to rotate, thereby driving the rotating screw 9 to rotate and drive the stop rack 8 to slide. According to this principle, the stop rack 8 can be driven to slide back into the limit cavity 7 by pressing the sliding rack 11, so that the first rotating block 2 and the second rotating block 3 are in a free rotation state, and the stator and rotor that have been detected can be removed from the detection device.

[0018] The sliding rack 11 is provided with a limit block 13 and a spring 14. A limit groove 15 is provided on the inner side wall of the limit cavity 7. One end of the limit block 13 can be welded and fixed to the side wall of the sliding rack 11. The other end of the limit block 13 can extend into the limit groove 15. The interference between the limit block 13 and the inner side wall of the limit groove 15 can prevent the sliding rack 11 from sliding out of the opening of the limit cavity 7, thereby ensuring the effective implementation of the sliding rack 11. One end of the spring 14 can be fixed to the limit groove 15. On the inner wall, the other end of the spring 14 can be fixedly connected to the partial limit block 13 extending into the limit groove 15. The elastic action of the spring 14 can push the limit block 13 to slide in the limit groove 15, that is, push the sliding rack 11 back to the initial position, and also drive the stop rack 8 to slide into the stop cavity 5, that is, when the stop block 4 extends into the stop cavity 5, it ensures that the stop rack 8 is stably extended into the card slot 12, ensuring the stable connection between the first rotating block 2 and the second rotating block 3.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
