Hair-pin motor shaping mechanism

Abstract

The invention relates to a hair-pin motor shaping mechanism which comprises a bottom plate, a stator frame, and a line folding structure. The stator frame is fixed on the upper surface of the bottom plate. The line folding structure is arranged in the stator frame, and the line folding structure comprises a first line folding part, a second line folding part, a third line folding part and a fourth line folding part. The first line folding part, the second line folding part, the third line folding part and the fourth line folding part can rotate relative to one another, and the upper ends of the first line folding part, the second line folding part, the third line folding part and the fourth line folding part are provided with a plurality of first line folding grooves, second line folding grooves, third line folding grooves and fourth line folding grooves which are formed in the circumferential direction of the axis of the stator frame respectively. The first line folding grooves are communicated with the second line folding grooves. The third line folding grooves are communicated with the fourth line folding grooves. The first line folding grooves, the second line folding grooves, the third line folding grooves and the fourth line folding grooves are matched with flat line groups. The stator frame is connected with a limiting structure for limiting the position of the stator. The hair-pin motor shaping mechanism has the effect that the twisting degrees of the multiple flat line groups are the same.

Description

technical field [0001] The present application relates to the field of hairpin motor processing equipment, in particular to a hairpin motor shaping mechanism. Background technique [0002] The card-generating motor is also called a flat wire motor. It has the characteristics of small size, high power and high torque. It meets the needs of the development of new energy vehicles and the development trend of the industry. It will definitely have a large room for development in the future. [0003] At present, the production process of card-generating motors is complicated, and the production of many card-generating motors is still in a semi-automatic production state in which the stator is clamped manually with a jig. The production process is to first insert the flat wire groups into the stator group by group, and then bend and shape the lower end of the flat wire groups, refer to figure 1 The flat wire group 5 includes A wire 51 and B wire 52, both of which are U-shaped, and...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that after bending the lower ends of multiple flat wire groups 5, different flat wire groups 5 have different bending degrees, which affects the quality of the card generator.
