[0034] Figure 1 The following is a schematic diagram showing the structure of the motor assembly device provided by the embodiment of the present invention. Figure 1 This embodiment provides a motor assembly device. The motor assembly device includes a base unit 100, a rotor positioning unit 200, and a stator adjustment unit 300. The rotor positioning unit 200 includes a rotor fixing mechanism 210 and a rotor hoisting mechanism 220. The rotor fixing mechanism 210 is slidably connected to the base unit 100 along the X direction. The rotor hoisting mechanism 220 is mounted on the rotor fixing mechanism 210 and is configured to hoist the motor rotor. The stator adjustment unit 300 is mounted on the base unit 100 and is configured to position the motor stator. The rotor fixing mechanism 210 slides on the base unit 100 and can adjust the distance between the motor rotor and the motor stator. In other words, during the motor assembly process, the stator adjustment unit 300 is used to position the motor stator, and then the motor rotor is mounted on the rotor hoisting mechanism 220. The rotor fixing mechanism 210 drives it to move closer to the motor stator, thereby achieving accurate assembly of the motor rotor and the motor stator.

[0035] Figure 2 Show Figure 1 A partial enlarged view of the structure marked as A. Figure 3 FIG2 shows a schematic diagram of a portion of the structure of the motor assembly device provided by an embodiment of the present invention. Figure 1-Figure 3 The base unit 100 includes a base body 110 and a slide rail 120 . The slide rail 120 is mounted on the base body 110 parallel to the X direction. The rotor fixing mechanism 210 is slidably connected to the slide rail 120 . The stator adjustment unit 300 is mounted on the base body 110 .

[0036] Specifically, two slide rails 120 are provided on the base body 110. Both slide rails 120 are arranged parallel to the X-direction and spaced apart in the Y-direction, with the distance between them being equal to the width of the rotor securing mechanism 210. The use of two slide rails 120 ensures the reliable mounting of the rotor securing mechanism 210, ensuring the stability of the rotor securing mechanism 210 as it moves along the slide rails 120, thereby preventing the motor rotor from swinging and improving the accuracy of the assembly of the electronic rotor and the motor stator.

[0037] More specifically, the motor assembly device further includes an electronic control unit, and the base unit 100 further includes a drive mechanism. A slider 130 is slidably mounted on the slide rail 120, and the rotor fixing mechanism 210 is fixedly connected to the slider 130. The drive mechanism is connected to the slider 130 and is capable of driving the slider 130 to slide along the slide rail 120. The electronic control unit is electrically connected to the drive mechanism and is configured to control the opening and closing of the drive mechanism. In this embodiment, the drive mechanism can be a hydraulic drive cylinder assembly in the prior art, whose telescopic rod is connected to the slider 130, and the telescopic rod is controlled by hydraulic pressure, thereby controlling the movement of the slider 130 along the slide rail 120. The electronic control unit is a prior art, and its specific structure and principle are not described in detail in this embodiment.

[0038] More specifically, if Figure 2 As shown, a slide groove is defined at the bottom of the slider 130, and a sliding ridge is provided on the upper side of the slide rail 120, which is embedded in the groove. The top of the slider 130 is fixedly connected to the bottom of the rotor fixing mechanism 210. This arrangement ensures the reliability of the connection between the rotor fixing mechanism 210 and the slide rail 120, ensuring the stability of the rotor fixing mechanism 210 without hindering its sliding, and preventing it from derailing during sliding, which could cause misalignment between the motor rotor and stator.

[0039] Figure 4 The schematic diagram of the structure of the rotor fixing mechanism provided by the embodiment of the present invention is shown. Figure 1 and Figure 4 The rotor fixing mechanism 210 includes a mobile frame 211 and a lifting rod assembly. The bottom of the mobile frame 211 is fixedly connected to the slider 130 and is slidably connected to the base unit 100 through the slider 130. The lifting rod assembly is connected to the top of the mobile frame 211. The rotor lifting mechanism 220 includes a connecting rod 221 and a rotor connecting member 222. The connecting rod 221 is connected to the lifting rod assembly. The rotor connecting member 222 is connected to the end of the connecting rod 221 away from the lifting rod assembly and is configured to connect to the short shaft of the motor rotor.

[0040] Specifically, the hoisting rod assembly includes a connecting plate 212 and a first hoisting rod 213 and a second hoisting rod 214 that are spaced apart and parallel to each other. The connecting plate 212 is mounted on the first hoisting rod 213 and the second hoisting rod 214. In this embodiment, the first hoisting rod 213 and the second hoisting rod 214 are parallel to the X direction and spaced apart from each other along the Y direction.

[0041] More specifically, Figure 5 The schematic diagram of the structure of the rotor hoisting mechanism provided by the embodiment of the present invention is shown. Figure 5 A connecting block 223 is fixedly mounted on the connecting rod 221. The thickness of the connecting block 223 is less than the distance between the first hoisting rod 213 and the second hoisting rod 214. The connecting block 223 is sandwiched between the first hoisting rod 213 and the second hoisting rod 214 and connected to the connecting plate 212. In this embodiment, a first threaded hole is defined at the geometric center of the connecting plate 212, and a second threaded hole is defined at the geometric center of the top end of the connecting block 223. Bolts are threaded into the first and second threads to securely connect the rotor hoisting mechanism 220 to the rotor fixing mechanism 210.

[0042] More specifically, the connecting rod 221 is L-shaped, comprising a vertical rod portion and a horizontal rod portion that are fixedly connected perpendicularly to each other. The connecting block 223 is sleeved onto the horizontal rod portion, and a retaining plate is provided at the end of the horizontal rod portion away from the vertical rod portion. This retaining plate is larger than the cross-sectional dimensions of the horizontal rod portion, effectively preventing the connecting block 223 from falling off the horizontal rod portion.

[0043] More specifically, the rotor connector 222 is a cylindrical structure with a mounting through hole, and can be sleeved on the short shaft of the motor rotor to achieve positioning and connection between the motor rotor and the rotor hoisting mechanism 220 .

[0044] Continue to refer to Figure 1 and Figure 3 The rotor positioning unit 200 further includes a rotor auxiliary positioning mechanism 230, which is located below the rotor fixing mechanism 210. The rotor auxiliary positioning mechanism 230 can support the motor rotor when it is mounted on the rotor hanging mechanism 220 and adjust the height of the motor rotor so that it is accurately connected to the rotor connecting member 222.

[0045] Specifically, the rotor auxiliary positioning mechanism 230 includes an auxiliary base 231, a height adjustment leg 232 and a rotor support block 233. The auxiliary base 231 can be detachably arranged on the base unit 100. The fixed end of the height adjustment leg 232 is installed on the auxiliary base 231. The rotor support block 233 is installed on the telescopic end of the height adjustment leg 232. The rotor support block 233 can support the motor rotor.

[0046] More specifically, the height-adjusting legs 232 may be electrically controlled hydraulic rods, including hydraulic cylinders and support rods. The support rods are capable of lifting the rotor support block 233, and the extension and contraction of the support rods are controlled by the hydraulic cylinders to adjust the height of the rotor support block 233.

[0047] More specifically, the upper end surface of the rotor support block 233 defines a receiving groove configured to match the circumferential shape of the motor rotor, with the motor rotor embedded within the groove. This groove prevents the motor rotor from rolling on the rotor support block 233, thereby increasing the connection speed between the motor rotor's stub shaft and the rotor connector 222.

[0048] Reference Figure 1 and Figure 3 The stator adjustment unit 300 includes a positioning base 310 , a positioning platform 320 and an adjustment component 330 .

[0049] Specifically, the positioning base 310 is connected to the base unit 100, the positioning platform 320 is movably arranged on the positioning base 310 and is configured to carry the motor stator, and the adjustment component 330 is arranged on the positioning base 310 and is configured to adjust the relative position of the positioning platform 320 and the positioning base 310 along the Y direction.

[0050] More specifically, the stator adjustment unit 300 also includes a plurality of limit blocks 340, which are disposed on the bearing surface of the positioning platform 320. The motor stator is mounted between these limit blocks 340. In this embodiment, four limit blocks 340 are disposed on the positioning platform 320, arranged in a rectangular array. Each limit block 340 defines a rounded abutment groove, against which the four corners of the motor stator base can abut to achieve positioning.

[0051] More specifically, the adjustment assembly 330 includes a plurality of support plates 331 and a plurality of adjustment screws 332. The support plates 331 correspond one to one with the adjustment screws 332. The support plates 331 are uniformly fixed to opposite sides of the positioning base 310 in the Y direction. The adjustment screws 332 are parallel to the Y direction and threaded through the support plates 331, with their ends capable of abutting against the sides of the positioning platform 320. In this embodiment, two support plates 331 are provided on opposite sides of the positioning base 310 in the Y direction, with an adjustment screw 332 threaded into each support plate 331.

[0052] The process of using the motor assembly device provided in this embodiment is as follows:

[0053] First, the motor rotor is hoisted onto the rotor auxiliary positioning mechanism 230. The height of the motor rotor is adjusted to the appropriate position. The rotor connector 222 is assembled with the short shaft of the motor rotor. The rotor hoisting mechanism 220 is then assembled onto the rotor fixing mechanism 210. The rotor auxiliary positioning mechanism 230 is then removed, and the motor stator is hoisted onto the positioning platform 320. The position of the motor stator is then adjusted and positioned using the adjustment assembly 330. The electronic control unit then activates the drive mechanism, causing the rotor fixing mechanism 210 to gradually move the motor rotor closer to the stator, ultimately completing assembly. Finally, the position of the motor end cap is manually adjusted and the bolts are installed, completing the motor assembly.

[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
