Specifically, the lifting claw 210 may be coupled to the second base plate 120 via a non-rigid coupling such as a universal joint 212, so that the rotor 104 may be positionally adjusted in the air during subsequent positioning.

The positioning mechanism 300 is disposed between the first substrate 110 and the hanging claw 210, and the positioning mechanism 300 can be fixed by a positioning bracket 302. In this example, the first substrate 110 and the lifting claw 210 can be moved relative to the positioning mechanism 300 by the push-pull driving of the first driving mechanism 112 and the second driving mechanism 122, and in other alternative embodiments, the first substrate 110 and the lifting claw 210 may be configured to be fixed, and the positioning mechanism 300 may be driven to move relative to the first substrate 110 and the lifting claw 210.

When the two handles 332 are opened, the outer sidewall of the stator positioning claws 310 may form a first circumference to be tightly fitted with the inner circumferential wall of the stator assembly 101, and the inner sidewall of the rotor positioning claws 320 may form a second circumference to be clamped with the outer circumferential wall of the rotor 104.

Then, the second driving mechanism 122 drives the lifting claw 210 to descend toward the positioning mechanism 300 for the second concentric adjustment, and after the second concentric adjustment is completed, the first driving mechanism 112 drives the first substrate 110 to ascend toward the positioning mechanism 300 so that the top end of the stator group 101 is sleeved on the bottom end of the rotor 104, and then the rotor positioning claw 320 is opened and the second driving mechanism 122 drives the lifting claw 210 to continuously load the rotor 104 into the stator group 101.
