In addition to the first embodiment, the second embodiment provides a stator assembly fixture 1, as shown in fig. 6, the bending surface 232 includes a first sub-bending surface 234 and a second sub-bending surface 236 distributed in parallel around the central axis of the insulating member molding member 200, and the first sub-bending surface 234 protrudes from the second sub-bending surface 236.

In this embodiment, as previously described, both ends of the insulator 424 extend out of the stator slots, as shown in fig. 22, and therefore both sections of the structure need to be bent, which are referred to as a first bent section 426 and a second bent section 428, respectively. By configuring the bending surface 232 as a first sub-bending surface 234 and a second sub-bending surface 236 which are arranged side by side left and right, the first bending section 426 of the insulating element 424 can be bent by the first sub-bending surface 234, and the second bending section 428 of the insulating element 424 can be bent by the second sub-bending surface 236. Meanwhile, the first sub-bending surface 234 protrudes out of the second sub-bending surface 236, that is, the first sub-bending surface 234 is closer to the inside of the insulating member forming member 200 than the second sub-bending surface 236, and a step surface fault is formed at the joint of the first sub-bending surface 234 and the second sub-bending surface 236, but not kept flush with each other, so that the step surface fault can be matched with the lengths of the first bending segment 426 and the second bending segment 428, and the first bending segment 426 and the second bending segment 428 are bent successively, and the final bending effect is as shown in fig. 24, so that the insulating member 424 is ensured to be bent smoothly, the first bending segment 426 and the second bending segment 428 are prevented from being bent simultaneously to interfere with each other, and the processing efficiency is improved.

Further, in some embodiments, as shown in FIG. 6, the width of first bending sub-surface 234 is different from the width of second bending sub-surface 236.

In this embodiment, different widths are further provided for the first bending sub-surface 234 and the second bending sub-surface 236, which can further match the lengths of the first bending segment 426 and the second bending segment 428, so as to ensure that the first bending segment 426 and the second bending segment 428 are bent successively without interference with each other, which helps to ensure that the insulating member 424 is bent smoothly, and improves the processing efficiency. It is understood that the width is specifically a dimension in a circumferential direction around a central axis of the insulating member molding member 200, and the width of the first sub-bending surface 234 is smaller than the width of the second sub-bending surface 236 in fig. 6, and the relationship between the widths is merely illustrative and not limited to the magnitude relationship.

Further, in some embodiments, the bending surface 232 includes a curved surface having a different radius of curvature at two ends facing away from each other in the height direction of the insulating member molding member 200.

In this embodiment, the bending surface 232 is specifically defined as a gently-transitional curved surface, which helps to guide the end of the insulating member 424 to gradually move toward the stator slot, so that the insulating member 424 is smoothly bent, damage to the insulating member 424 by the insulating member bending portion 230 can be reduced, the bending efficiency can be improved, and the yield can be increased. By having different radii of curvature at the two ends of the curved surface, specifically, the radius of curvature of the curved surface towards the end of the stator tooth assembly 4 is smaller than the radius of curvature of the curved surface away from the end of the stator tooth assembly 4. That is, the end of the bent insulator part 230 facing the stator tooth assembly 4 first contacts the insulator 424, and the radius of curvature of the bent insulator part 230 is set to be smaller, i.e., the degree of bending is larger, the distance between the bent insulator part and the central axis of the molded insulator 200 is larger, and the bent insulator part can be adapted to the shape of the insulator 424 which is not bent. Accordingly, the radius of curvature of the end of the insulator bending part 230 away from the stator tooth assembly 4 is set to be smaller, that is, the bending degree is smaller, the distance between the end and the central axis of the insulator molding part 200 is smaller, and the shape of the insulator 424 can be adapted to the bending shape, so as to realize effective bending. Specifically, the curvature radius of the curved surface gradually changes along the height direction of the insulating member molding member 200 to ensure that the insulating member 424 is smoothly bent and molded, and the insulating member 424 can be guided to be bent and closed.
