[0035] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0038] like Figures 1 to 4As 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 hoisting unit 4. The worktable 2 includes a first slide 21, a support platform 22 mounted on the first slide 21, and a stator fixing assembly 23. The first slide 21 is adjustable along the X-axis on the frame 1. The support platform 22 supports the motor rotor, and the stator fixing assembly 23 is used to fix and install the motor stator. The rotor adjustment unit 3 includes a second slide 31, a third slide 32, and a clamp 33. The second slide 31 is slidably mounted on the frame 1 along the Z-axis. The third slide 32 is adjustable along the Y-axis on the second slide 31. The clamp 33 is mounted on the third slide 32 and is used to clamp the central shaft of the motor rotor. The rotor hoisting unit 4 includes a gantry frame 41, a drive component 42, and a connecting component 43. The connecting component 43 is fixedly connected to the clamp 33. The drive component 42 is mounted on the gantry frame 41 and is used to adjust the Z-axis position of the connecting component 43. It can be understood that the X, Y, and Z axes are mutually perpendicular, forming a three-dimensional coordinate system. The drive component 42 can be a hydraulic cylinder or a pneumatic cylinder.

[0039] Since the first slide 21 is adjustable in position along the X-axis on the frame 1, and the clamp 33 is adjustable in position along the Y-axis on the second slide 31, and the second slide 31 is slidably mounted on the frame 1 along the Z-axis, and the connecting member 43 is fixedly connected to the clamp 33, the Z-axis position of the connecting member 43 is adjusted by the driving member 42 on the gantry 41, thereby driving the Z-axis position adjustment of the entire rotor adjustment unit 3. This achieves relative position adjustment of the clamp 33 and the motor rotor on the support platform 22 in three dimensions, facilitating the alignment of the clamp 33 with the motor rotor on the support platform 22. The clamp 33 can smoothly hold the central shaft of the motor rotor, making operation convenient and applicable to a wide range of applications. Since the first slide 21 is adjustable in position along the X-axis on the frame 1, the motor stator on the stator fixing assembly 23 can be smoothly moved to the position for assembly with the motor rotor, ensuring accurate alignment of the motor stator and the motor rotor. The motor stator and rotor assembly equipment has a reasonable structure, occupies little space, is safe and reliable, is easy to operate, and has a high degree of automation. 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.

[0040] To accommodate the fixed installation of motor stators of various sizes, the stator fixing assembly 23 optionally includes a fixing member 231. The fixing member 231 is adjustablely positioned on the first slide block 21 along the X-axis and is used to fix the motor stator. A fixing pin 234 may be provided on the fixing member 231, which can be inserted into the pin hole of the motor stator to achieve the installation and positioning of the fixing member 231 and the motor stator, thereby achieving coaxial positioning of the motor stator and the motor rotor. An adjusting screw 235 and an adjusting nut may be provided on the fixing member 231, and an installation groove 211 is provided on the first slide block 21. The adjusting screw 235 and the adjusting nut enable a detachable connection between the fixing member 231 and the installation groove 211 and allow for adjustment of the installation position, thus accommodating the fixed installation of motor stators of various sizes.

[0041] Optionally, the stator fixing assembly 23 further includes a first limiting member 232 and a second limiting member 233. Both the first limiting member 232 and the second limiting member 233 are adjustablely mounted on the first slide block 21 along the X-direction. The first limiting member 232 and the second limiting member 233 can respectively abut against both sides of the motor stator. Adjusting screws 235 and adjusting nuts can be provided on the first limiting member 232 and the second limiting member 233. The adjusting screws 235 and adjusting nuts enable detachable connection and installation position adjustment between the first limiting member 232 or the second limiting member 233 and the mounting groove 211, thereby meeting the limiting requirements of motor stators of various sizes.

[0042] Optionally, the connector 43 includes a first rod 431, a second rod 432, a first clamping part 433, and a second clamping part 434. The output end of the drive member 42 is connected to the first rod 431, the first rod 431 is connected to the second rod 432, the first clamping part 433 is connected to the second rod 432, and the second clamping part 434 is detachably connected to the first clamping part 433. The first rod 431 and the second rod 432 can be connected perpendicularly to facilitate avoiding the motor rotor. Both the first clamping part 433 and the second clamping part 434 can be semi-circular structures.

[0043] 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 spaced apart on the frame 1. The two end cover adjustment units are used for the end cover of the rotating motor rotor and the end cover of the motor stator, respectively.

[0044] Optionally, the end cover adjustment unit includes a positioning rod, a fixed base, and a friction wheel. The positioning rod is adjustable along the Y-axis on the frame 1, the fixed base is mounted on the positioning rod, and the friction wheel is rotatably mounted on the fixed base. The friction wheel can abut against the motor rotor end cover or the motor stator end cover. Because the positioning rod is adjustable along the Y-axis on the frame 1, the friction wheel can extend to abut against the motor rotor end cover or the motor stator end cover. Rotating the friction wheel aligns the mounting holes of the motor rotor end cover with the mounting threaded holes of the motor stator end cover. The end cover adjustment unit may also include a drive motor, which is mounted on the fixed base and drives the friction wheel to rotate, thereby achieving automated adjustment of the motor rotor end cover and the motor stator end cover.

[0045] Optionally, a fixed frame is provided on the frame 1, and a fixed cylinder is provided on the fixed frame, with the positioning rod slidingly engaged with the fixed cylinder. The fixed cylinder can be the cylinder body of a hydraulic rod, and the positioning rod can be the piston rod of a hydraulic rod.

[0046] Optionally, the frame 1 includes a mounting base 11 and a mounting bracket 12 disposed on the mounting base 11. A first slide 21 is adjustablely disposed on the mounting base 11 along the X direction, and a second slide 31 is slidably disposed on the mounting bracket 12 along the Z direction. The mounting bracket 12 can be a gantry frame structure to facilitate avoidance of the first slide 21.

[0047] Optionally, the 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 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.

[0048] 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.

[0049] 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 21 on the frame 1 is adjusted so that the motor rotor on the support platform 22 is close to the clamp 33. Second, the connecting member 43 is driven by the drive member 42, and the Z-axis position of the clamp 33 is adjusted by the second slide 31. Then, the Y-axis position of the clamp 33 is adjusted by the third slide 32 so that the clamp 33 can hold the central shaft of the motor rotor. Next, the Z-axis position of the second slide 31 on the frame 1 is adjusted so that the motor rotor reaches a height suitable for assembly with the motor stator. Finally, the X-axis position of the first slide 21 is adjusted so that the fixing component avoids the gantry frame 41. The crane is used to suspend the motor stator onto the stator fixing component 23. The X-axis position of the first slide 21 is then adjusted so that the motor stator and motor rotor are assembled, and all assembly screws are tightened into place. It is understood that the above position adjustment process can be achieved through the control system and drive system, and will not be elaborated further here.
