[0029] The present invention will be further described with reference to the accompanying drawings.

[0030] like Figures 1 to 8As shown, a new energy vehicle motor stator rotor separation device includes a fixed top plate 1, a fixed frame 2 and an ejection device 3. The fixed top plate 1 is installed on the top of the fixed frame 2, and the ejection device 3 is installed inside the fixed frame 2 and is located below the fixed top plate 1. An ejection hole 12 and a plurality of fixed waist holes 11 are provided on the fixed top plate 1. The ejection hole 12 is located at the center of the fixed top plate 1, and the fixed waist holes 11 are arranged in a ring around the ejection hole 12. The ejection device 3 is arranged opposite to the ejection hole 12, usually coaxially, and the ejection device 3 is used to eject the rotor 62 upward from the stator 61 to achieve the separation of the rotor 62 from the stator 61.

[0031] When in use, the stator 61 is fixed in the fixed waist hole 11 of the fixed top plate 1 by a bolt assembly, the bolts of the bolt assembly pass through the screw holes and the fixed waist hole 11 on the stator 61, the stator 61 is coaxially arranged with the ejection hole 12 or the ejection device 3, and then the ejection device 3 is started, and the ejection device 3 ejects the rotor 62 upward from the stator 61.

[0032] Since the rotor 62 is ejected from the stator 61 in the vertical direction, the ejection position of the stator 61 can be controlled, and no other mechanism is needed to support the ejected rotor 62. When the rotor 62 is ejected to a suitable position, the rotor 62 can be removed from the stator 61, which is very convenient to use, greatly shortens the disassembly time of the motor, and improves the maintenance efficiency.

[0033] The stator-rotor separation device of the new energy vehicle motor has few parts and a simple structure, so it is low in cost, simple to operate and easy to use.

[0034] In order to improve versatility and adapt to more types and specifications of motors, the fixed waist holes 11 are arranged in a circular array along the axis of the ejection hole 12. The fixed waist holes 11 arranged in a circular array can adapt to a variety of motors.

[0035] The waist-shaped fixing waist hole 11 can also be arranged along the radial direction of the ejection hole 12, that is, the length direction of the fixing waist hole 11 is arranged along the radial direction of the ejection hole 12, so as to be suitable for motors with different diameters.

[0036] In order to adapt to more motors, a plurality of second fixing holes 13 are provided on the fixed top plate 1. The second fixing holes 13 can be arranged in a circular array along the axis of the ejection hole 12, and the second fixing holes 13 are fan-shaped.

[0037] The fixed frame 2 includes a fixed bottom plate 22 and a fixed column 21. The two ends of the fixed column 21 are respectively connected to the fixed top plate 1 and the fixed bottom plate 22. Four fixed columns 21 can be provided, and they are respectively located at the four corners of the rectangular fixed top plate 1. The fixed top plate 1 can be a rectangular plate or a circular plate. Figure 6 shown.

[0038] like Figure 1 and Figure 6 As shown, the fixed column 21 can be a rectangular tube or a circular tube. The rectangular fixed top plate 1 can be matched with the circular fixed column 21, the circular fixed top plate 1 can be matched with the circular fixed column 21, or the circular fixed top plate 1 can be matched with the rectangular fixed column 21.

[0039] In order to facilitate the mobile position, the fixed frame 2 also includes a universal caster 23, and the universal caster 23 is provided with four and is evenly fixed at the bottom of the fixed base plate 22. The four universal casters 23 can all be universal casters 23 with brakes, or they can partially be universal casters 23 with brakes.

[0040] In order to reduce costs and make the structure and operation convenient, the ejection device 3 includes an ejection cylinder 31 and an ejection plate 32. The ejection cylinder 31 is fixed on the fixed bottom plate 22 and is coaxially arranged with the ejection hole 12, while the ejection plate 32 is fixed to the end of the piston rod of the ejection cylinder 31, and the diameter of the ejection plate 32 is smaller than the diameter of the rotor 62. The diameter of the ejection plate 32 can be set according to the diameter of the rotor. The ejection plate 32 is used to increase the contact area with the shaft of the rotor 62, can be applied to different motors, and can easily eject the rotor 62, reduce the requirement that the rotor 62 is coaxial with the ejection cylinder 31, make the installation of the motor more convenient, and reduce the alignment time.

[0041] The ejection cylinder 31 includes any one of a pneumatic cylinder, a hydraulic cylinder or an electric cylinder. The use of a standard pneumatic cylinder, a hydraulic cylinder or an electric cylinder can effectively reduce costs and has good reliability and stability. When a hydraulic cylinder is used, a manual hydraulic cylinder or an electric hydraulic cylinder can be used, which needs to be matched with an oil tank. The manual hydraulic cylinder can be a commonly used hydraulic jack, which realizes the ejection of the piston rod by hand pressure, has a simple structure and low cost.

[0042] In order to facilitate the fixation of the stator 61, a movable clamping device 5 is also included, which is installed on the fixed waist hole 11 and is used to fix the stator 61 on the fixed top plate 1. Specifically, the clamping device 5 includes an arched pressure plate assembly or a toothed pressure plate assembly. The use of a standard arched pressure plate assembly or a toothed pressure plate assembly can provide versatility, low cost, and easy use.
