A worm gear located below the rotating ring is rotatably connected to the movable base. A worm wheel is fixedly installed on the outer circumference of the rotating ring. The bottom of the worm wheel meshes with the worm gear. A second handwheel is fixedly installed at one end of the worm gear. A drive groove is opened in the middle of the rotating ring. A guide groove corresponding to the drive groove is opened in the middle of the support frame. A movable column is slidably connected inside the drive groove and the guide groove. A connecting block is integrally connected to one end of the movable column. A clamping arc plate is fixedly installed on the side of the connecting block.

[0007] Optionally, the top of the movable frame is fixedly installed with guide slide rods located on both sides of the threaded rod, and the guide slide rods are slidably connected to both sides of the bottom of the movable base.

[0008] Optionally, a rubber protective pad is bonded to the inner arc surface of the clamping arc plate.

[0009] Optionally, the guide groove and the drive groove have the same width, and the width of the guide groove and the drive groove is the same as the diameter of the moving column.

[0010] Optionally, the centerline of the drive slide groove intersects with the centerline of the guide slide groove, and the extension line of the centerline of the guide slide groove intersects with the center of the rotating ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This new energy vehicle motor stator and rotor testing device uses a clamping arc plate. The stator is placed on one side of the stand. Rotating the second handwheel causes the worm gear to drive the worm wheel to rotate, which in turn causes the rotating ring to rotate. As the rotating ring rotates, the moving column moves along the drive slide groove and then along the guide slide groove. The clamping arc plate clamps the stator, making the stator more secure and greatly improving the stability of the equipment.

[0015] This new energy vehicle motor stator and rotor testing device uses a threaded rod and a clamping arc plate to fix the stator. After the stator is fixed, the first handwheel is rotated, which causes the moving base to move along the guide slide rod, thereby driving the upright to move the fixed stator smoothly to the outside of the rotor.

[0021] 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.

[0022] Please see Figures 1 to 4 This utility model provides a testing device for the stator and rotor of a new energy vehicle motor, including a workbench 1. A drive motor 2 is fixedly installed on the top of the workbench 1. A movable frame 4 located on one side of the drive motor 2 is fixedly installed on the top of the workbench 1. A fixed frame 3 for mounting the rotor is provided at the output end of the drive motor 2. A threaded rod 5 is rotatably connected to the middle of the top of the movable frame 4. A movable base 6 is slidably arranged inside the movable frame 4. A first handwheel 8 located outside the movable frame 4 is fixedly installed at one end of the threaded rod 5. The threaded rod 5 and the middle of the movable base 6 are threadedly connected. A stand 9 is integrally connected to the top of the movable base 6. A rotating ring 10 is rotatably connected to the side of the stand 9 away from the drive motor 2. A worm gear 11 located below the rotating ring 10 is rotatably connected to the movable base 6. A worm wheel 12 is fixedly installed on the outer circumference of the rotating ring 10. The bottom of the worm wheel 12 is connected to the worm. The worm gear 11 is engaged, and a second handwheel 13 is fixedly installed at one end of the worm gear 11. A drive groove 14 is opened in the middle of the rotating ring 10, and a guide groove 16 corresponding to the drive groove 14 is opened in the middle of the upright frame 9. A moving column 15 is slidably connected inside the drive groove 14 and the guide groove 16. A connecting block 17 is integrally connected to one end of the moving column 15. A clamping arc plate 18 is fixedly installed on the side of the connecting block 17. By setting the clamping arc plate 18, the stator is placed on one side of the upright frame 9. Rotating the second handwheel 13 causes the worm gear 11 to drive the worm wheel 12 to rotate, which in turn causes the rotating ring 10 to rotate. As the rotating ring 10 rotates, the moving column 15 moves along the drive groove 14 and drives the moving column 15 to move along the guide groove 16. The stator is clamped by the clamping arc plate 18, making the stator more firmly fixed, thereby greatly improving the stability of the equipment.

[0023] The top of the movable frame 4 is fixedly installed with guide slide rods 7 located on both sides of the threaded rod 5. The guide slide rods 7 are slidably connected to both sides of the bottom of the movable base 6. After the stator is fixed by the clamping arc plate 18 by setting the threaded rod 5, the first handwheel 8 is rotated, which causes the movable base 6 to move along the guide slide rod 7, thereby driving the upright frame 9 to move the fixed stator smoothly to the outside of the rotor.

[0024] A rubber protective pad is bonded to the inner arc surface of the clamping arc plate 18.

[0025] The guide slide 16 and the drive slide 14 have the same width, and the width of the guide slide 16 and the drive slide 14 is the same as the diameter of the moving column 15.

[0026] The centerline of the drive slide 14 intersects the centerline of the guide slide 16, and the extended line of the centerline of the guide slide 16 intersects the center of the rotating ring 10.

[0027] A groove is provided on one side of the support frame 9 that overlaps with the guide groove 16, and the connecting block 17 is slidably connected to the inside of the groove.

[0028] A circular through hole is provided in the middle of the support frame 9, and the inner diameter of the rotating ring 10 is larger than the diameter of the through hole.

[0029] Working principle:

[0030] The stator is placed on one side of the support frame 9. The second handwheel 13 is turned, which causes the worm gear 11 to drive the worm wheel 12 to rotate, which in turn causes the rotating ring 10 to rotate. As the rotating ring 10 rotates, the moving column 15 moves along the drive slide groove 14 and drives the moving column 15 to move along the guide slide groove 16. The stator is clamped by the clamping arc plate 18, making the stator more firmly fixed. After the stator is fixed by the clamping arc plate 18, the first handwheel 8 is turned, which causes the moving base 6 to move along the guide slide rod 7, which in turn drives the support frame 9 to move the fixed stator smoothly to the outside of the rotor.
