Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0030] In addition, if there are descriptions involving "first", "second" and so on in ...

The invention provides a motor assembling and positioning device. The device comprises a first substrate, a lifting claw and a positioning mechanism, and the first substrate is used for placing a stator group; the lifting claw is arranged above the first substrate and is used for lifting the rotor; the positioning mechanism is arranged between the first base plate and the lifting claw, the positioning mechanism comprises a stator positioning claw and a rotor positioning claw which can be opened or closed, and the center of the stator positioning claw and the center of the rotor positioning claw are concentrically arranged; the stator positioning claw is used for extending into the top end of the stator group in a folded state and is unfolded to be matched with the inner circumferential wall of the top end of the stator group, so that the placement position of the stator group on the first substrate is adjusted, and the center of the top end of the stator group and the center of the stator positioning claw are concentrically adjusted for the first time; and the rotor positioning claw is used for receiving the rotor to extend in in an open state and is folded to clamp the outer peripheral wall of the rotor, so that the axis of the rotor and the center of the rotor positioning claw realize secondary concentric adjustment. The device is novel in structure and convenient to use.
Description
technical field [0001] The invention relates to the technical field of motor assembly, in particular to a motor assembly positioning device for installing a rotor into a stator group. Background technique [0002] One of the main steps of motor assembly is to install the rotor into the stator group (referred to as the stator group after the combination of the rear end cover and the stator). Stator group. [0003] However, in the prior art, when assembling the motor, the outer contour of the stator group is used as the reference for positioning. This positioning method requires that the axial center of the outer contour of the stator group and the axial center of the inner cavity of the stator group have a high degree of coaxiality. [0004] However, for a motor with a large axial dimension, it is difficult to ensure the coaxiality of the axis of the outer contour of the stator set and the axis of the inner cavity of the stator set. [0005] Therefore, the accuracy of posit...
