[0037] like Figures 1 to 4 As shown, this embodiment provides a motor stator and rotor assembly device, which includes a frame 1, a worktable 2, a rotor adjustment unit 3, and a rotor fixing unit 4. The worktable 2 includes a first slide 21, a support platform 22, and an assembly platform 23 disposed on the first slide 21. The first slide 21 is adjustable in position along the X-axis on the frame 1. The support platform 22 supports the motor rotor, and the assembly platform 23 places the motor stator and is capable of rotating the motor stator. The rotor adjustment unit 3 includes a second slide 31, a first clamp 32, and a first positioning rod 33. The second slide 31 is adjustable in position along the Z-axis on the frame 1. The first clamp 32 is adjustable in position along the Y-axis on the second slide 31 and is used to clamp the central shaft of the motor rotor. The first positioning rod 33 is adjustable in position along the X-axis on the second slide 31 and is used to abut against the motor rotor end cover. The first positioning rod 33 can be the piston rod of a hydraulic rod, and the cylinder of the hydraulic rod is mounted on the second slide 31. The rotor fixing unit 4 includes a second positioning rod 41 and a second clamp 42 mounted on the second positioning rod 41. The second positioning rod 41 is adjustable in position along the X direction on the frame 1. The second positioning rod 41 can pass through the center hole of the motor stator, and the second clamp 42 is used to clamp the center shaft of the motor rotor.
[0038] Since the first slide 21 is adjustable in position along the X-axis on the frame 1, the first clamp 32 is adjustable in position along the Y-axis on the second slide 31, and the second slide 31 is adjustable in position along the Z-axis on the frame 1, the relative positions of the first clamp 32 and the motor rotor on the support platform 22 can be adjusted in three dimensions. This facilitates the alignment of the first clamp 32 with the motor rotor on the support platform 22, and the first clamp 32 can smoothly hold the central shaft of the motor rotor. This design is convenient to operate and has a wide range of applications. Since the first positioning rod 33 is adjustable in position along the X-axis on the second slide 31, it can abut against the motor rotor end cover. Since the second positioning rod 41 is adjustable in position along the X-axis on the frame 1, it can pass through the central hole of the motor stator. The second clamp 42 can smoothly hold the central shaft of the motor rotor. The first clamp 32 and the second clamp 42 respectively hold the two ends of the central shaft of the motor rotor, ensuring the stability of the motor rotor during assembly. Since the first slide block 21 is adjustable along the X-axis on the frame 1, the motor stator on the assembly table 23 can be smoothly moved to the position for assembly with the motor rotor. Because the assembly table 23 can rotate the motor stator, accurate alignment between the motor stator and rotor is ensured. This motor stator-rotor assembly equipment has a reasonable structure, occupies little space, is safe and reliable, simple to operate, and highly automated. It reduces the number of operators, eliminates potential operational hazards, solves the instability problem during motor stator-rotor assembly, ensures the assembly accuracy of motor stator-rotor assembly, and improves the assembly efficiency of motor stator-rotor assembly.
[0039] To ensure that the mounting threaded holes of the motor stator are aligned with the mounting holes of the rotating motor rotor, the motor stator and rotor assembly equipment may optionally include two end cover adjustment units 5 spaced apart on the frame 1, which are used for the end cover of the rotating motor rotor and the end cover of the motor stator, respectively.

The third positioning rod 51 is adjustablely mounted on the frame 1 along the Y-direction, the fixed seat 52 is mounted on the third positioning rod 51, and the friction wheel 53 is rotatably mounted on the fixed seat 52. The friction wheel 53 can abut against the motor rotor end cover or the motor stator end cover. Because the third positioning rod 51 is adjustablely mounted on the frame 1 along the Y-direction, the friction wheel 53 can extend to abut against the motor rotor end cover or the motor stator end cover. Rotating the friction wheel 53 aligns the mounting hole of the motor rotor end cover with the mounting threaded hole of the motor stator end cover. The end cover adjustment unit 5 may also include a drive motor 54, which is mounted on the fixed seat 52 and is used to drive the friction wheel 53 to rotate, thereby achieving automated adjustment of the motor rotor end cover and the motor stator end cover.
[0041] Optionally, a fixed frame 14 is provided on the frame 1, and a fixed cylinder 141 is provided on the fixed frame 14. The third positioning rod 51 is slidably engaged with the fixed cylinder 141. The fixed cylinder 141 can be the cylinder body of the hydraulic rod, and the third positioning rod 51 can be the piston rod of the hydraulic rod.
[0042] Optionally, the assembly platform 23 includes a base 231 disposed on the first slide 21 and a rotary table 232 rotatably disposed on the base 231. The rotary table 232 is used to place the motor stator. The motor stator is rotated to face the motor rotor by the rotary table 232, which facilitates the subsequent alignment of the mounting thread holes of the motor stator with the mounting holes of the rotating motor rotor.
[0043] To ensure the stability of the motor rotor on the support platform 22, the support platform 22 may optionally be provided with an inverted trapezoidal receiving groove 221, which is used to receive the motor rotor.
[0044] To facilitate adjustment of the position of the first clamp 32 in the Y direction, the rotor adjustment unit 3 may optionally include a third slide 34, which is adjustablely mounted on the second slide 31 in the Y direction, and the first clamp 32 is mounted on the third slide 34.
[0045] Optionally, the frame 1 includes a mounting base 11 and a first mounting bracket 12 and a second mounting bracket 13 disposed on the mounting base 11. The first slide 21 is adjustablely disposed on the mounting base 11 along the X-axis, the second slide 31 is adjustablely disposed on the first mounting bracket 12 along the Z-axis, and the second positioning rod 41 is adjustablely disposed on the second mounting bracket 13 along the X-axis. The first mounting bracket 12 can be a gantry frame to facilitate avoidance of the first slide 21.
[0046] Optionally, the first mounting bracket 12 is provided with a slide rail 121, and the second slide block 31 is provided with a slider that slides in cooperation with the slide rail 121. Two slide rails 121 can be provided, with the two slide rails 121 spaced apart on the first mounting bracket 12. Two sliders are also provided, with the two sliders corresponding to the two slide rails 121 one by one, to ensure the sliding stability of the second slide block 31.
[0047] To ensure the movement accuracy of the second positioning rod 41, optionally, a guide cylinder 131 is provided on the second mounting bracket 13, and the second positioning rod 41 slides in conjunction with the guide cylinder 131. The guide cylinder 131 can be the cylinder body of a hydraulic rod, and the second positioning rod 41 can be the piston rod of a hydraulic rod.
[0048] The motor stator and rotor assembly equipment provided in this embodiment operates roughly as follows: First, a crane is used to suspend the motor rotor onto the support platform 22. The X-axis position of the first slide block 21 on the frame 1 is adjusted so that the motor rotor is close to the first clamp 32. Second, the Z-axis position of the second slide block 31 and the Y-axis position of the first clamp 32 are adjusted so that the first clamp 32 can hold the central shaft of the motor rotor. Then, the Z-axis position of the second slide block 31 on the frame 1 is adjusted so that the motor rotor reaches a height that facilitates assembly with the motor stator. Next, a crane is used to suspend the motor stator onto the rotary table 232, and the rotary table 232 rotates the motor stator to a position that is close to the motor rotor. The rotor and motor are coaxial; then, adjust the Y-axis position of the third positioning rod 51 so that the friction wheel 53 can extend to abut against the motor rotor end cover or the motor stator end cover, and rotate the friction wheel 53 so that the mounting hole of the motor rotor end cover is aligned with the mounting thread hole of the motor stator end cover; next, adjust the X-axis position of the first positioning rod 33 so that the first positioning rod 33 abuts against the motor rotor end cover, and adjust the X-axis position of the second positioning rod 41 so that the second positioning rod 41 passes through the center hole of the motor stator and clamps the motor stator end cover; finally, adjust the X-axis position of the first slide block 21 so that the motor stator and the motor rotor are assembled, and tighten all the assembly screws into place.
