Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] like Figures 1 to 6 As shown, this embodiment provides a motor stator and rotor assembly device, which includes a frame 1, a support platform 2, an assembly platform 3, a first positioning unit 4, and a second positioning unit 5. The support platform 2 is adjustablely positioned on the frame 1 along the Z-axis and is used to support the motor rotor. The assembly platform 3 is mounted on the frame 1 and is used to place the motor stator, and is capable of rotating the motor stator. The first positioning unit 4 includes a first positioning rod 41 and a first clamp 42 mounted on the first positioning rod 41. The first positioning rod 41 is adjustablely positioned on the frame 1 along the X-axis, and the first clamp 42 is used to clamp one end of the central shaft of the motor rotor. The second positioning unit 5 includes a second positioning rod 51 and a second clamp 52 mounted on the second positioning rod 51. The second positioning rod 51 is adjustablely positioned on the frame 1 along the X-axis and can pass through the central hole of the motor stator. The second clamp 52 is used to clamp the other end of the central shaft of the motor rotor.

[0042] Because the bearing platform 2 is adjustable along the Z-axis on the frame 1, the motor rotor on the bearing platform 2 can be adjusted to a Z-axis position that facilitates assembly with the motor stator. Since the assembly platform 3 can rotate the motor stator, accurate alignment between the motor stator and the motor rotor is ensured. Because the first positioning rod 41 and the second positioning rod 51 are adjustable along the X-axis on the frame 1, and the second positioning rod 51 can pass through the center hole of the motor stator, and the first clamp 42 and the second clamp 52 are used to clamp the two ends of the central shaft of the motor rotor, the first positioning rod 41 and the second positioning rod 51 together drive the motor rotor to move and assemble with the motor stator, ensuring the stability and accuracy of the motor rotor during the assembly process. This motor stator and 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 problem of instability during motor stator and rotor assembly, ensures the assembly accuracy of motor stator and rotor assembly, and improves the assembly efficiency of motor stator and rotor assembly.

[0043] To further ensure the stability of the motor rotor during assembly, the first positioning unit 4 may optionally include a third positioning rod 43. The third positioning rod 43 is adjustablely positioned on the first positioning rod 41 along the X-direction and can abut against the motor rotor end cover. The third positioning rod 43 can be a hydraulic rod or a cylinder rod. A fixing plate 44 is provided on the first positioning rod 41, and two third positioning rods 43 are disposed on the fixing plate 44, symmetrically arranged with respect to the first positioning rod 41.

[0045] 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 6 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.

[0046] Optionally, the end cover adjustment unit 6 includes a fifth positioning rod 61, a fixed seat 62, and a friction wheel 63. The fifth positioning rod 61 is adjustablely mounted on the frame 1 along the Y-axis, the fixed seat 62 is mounted on the fifth positioning rod 61, and the friction wheel 63 is rotatably mounted on the fixed seat 62. The friction wheel 63 can abut against the motor rotor end cover or the motor stator end cover. Because the fifth positioning rod 61 is adjustablely mounted on the frame 1 along the Y-axis, the friction wheel 63 can extend to abut against the motor rotor end cover or the motor stator end cover. Rotating the friction wheel 63 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 6 may also include a drive motor 64, which is mounted on the fixed seat 62 and is used to drive the friction wheel 63 to rotate, thereby achieving automated adjustment of the motor rotor end cover and the motor stator end cover.

[0047] Optionally, a fixed frame 14 is provided on the frame 1, and a fixed cylinder 141 is provided on the fixed frame 14. The fifth positioning rod 61 is slidably engaged with the fixed cylinder 141. The fixed cylinder 141 can be the cylinder body of the hydraulic rod, and the fifth positioning rod 61 can be the piston rod of the hydraulic rod.

[0048] Optionally, the assembly platform 3 includes a base 31 mounted on the frame 1 and a rotary table 32 rotatably mounted on the base 31. The rotary table 32 is used to place the motor stator. The motor stator is rotated to face the motor rotor by the rotary table 32, which facilitates the subsequent alignment of the mounting thread holes of the motor stator with the mounting holes of the rotating motor rotor.

[0049] To ensure the stability of the motor rotor on the support platform 2, the support platform 2 may optionally be provided with an inverted trapezoidal receiving groove 21, which is used to receive the motor rotor.

[0050] 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 support platform 2 is adjustablely disposed on the mounting base 11 along the Z-direction, the first positioning rod 41 is adjustablely disposed on the first mounting bracket 12 along the X-direction, and the second positioning rod 51 is adjustablely disposed on the second mounting bracket 13 along the X-direction. The first mounting bracket 12 and the second mounting bracket 13 are spaced apart at both ends of the mounting base 11, and the support platform 2 and the assembly platform 3 are located between the first mounting bracket 12 and the second mounting bracket 13.

[0051] To ensure the movement accuracy of the first positioning rod 41 and the second positioning rod 51, optionally, a first guide cylinder 121 is provided on the first mounting frame 12, and the first positioning rod 41 is slidably engaged with the first guide cylinder 121; a second guide cylinder 131 is provided on the second mounting frame 13, and the second positioning rod 51 is slidably engaged with the second guide cylinder 131.

[0052] The first positioning rod 41 can be the piston rod of the hydraulic rod, and the first guide cylinder 121 can be the cylinder of the hydraulic rod.

[0053] The second positioning rod 51 can be the piston rod of a hydraulic rod, and the second guide cylinder 131 can be the cylinder body of a hydraulic rod. Of course, the first positioning rod 41 and the second positioning rod 51 can also be driven by pneumatic pressure or electric motor.

[0054] Optionally, a base plate 24 is also fixedly installed on the frame 1. The base plate 24 is located below the support platform 2. A lifting rod 22 and a guide rod 23 are provided between the support platform 2 and the base plate 24. The lifting rod 22 serves as a driving component and is used to adjust the Z-axis position of the support platform 2. The lifting rod 22 can be a hydraulic rod or a pneumatic rod. The guide rod 23 plays a guiding and limiting role, ensuring the stable movement of the support platform 2.

[0055] 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 2. The Z-axis position of the support platform 2 on the frame 1 is adjusted so that the motor rotor reaches a height suitable for assembly with the motor stator. Then, the crane is used to suspend the motor stator onto the assembly platform 3. The motor stator is rotated to be coaxial with the motor rotor using the rotary table 32. Second, the X-axis position of the first positioning rod 41 on the frame 1 is adjusted so that the first clamp 42 holds one end of the central shaft of the motor rotor. The X-axis position of the second positioning rod 51 on the frame 1 is adjusted so that the second positioning rod 51 passes through the central hole of the motor stator. The second positioning rod 51 is then adjusted further. The X-axis position on frame 1 is adjusted so that the second clamp 52 holds the other end of the central shaft of the motor rotor. Then, the Y-axis position of the fifth positioning rod 61 is adjusted so that the friction wheel 63 can extend to abut against the motor rotor end cover or the motor stator end cover. The friction wheel 63 is rotated so that the mounting hole of the motor rotor end cover is aligned with the mounting thread hole of the motor stator end cover. Finally, the X-axis positions of the first positioning rod 41 and the second positioning rod 51 on frame 1 are adjusted so that the motor stator and the motor rotor are assembled. At the same time, the X-axis positions of the third positioning rod 43 and the fourth positioning rod 53 on frame 1 are adjusted to ensure the stable assembly of the motor stator and the motor rotor. Finally, all assembly screws are tightened into place. It is understood that the above position adjustment process can be achieved through the control system and the drive system, and will not be described in detail here.
