Block assembled stator punching structure

Abstract

The present invention relates to a block assembled stator punching structure. A stator punching is formed by splicing a plurality of equally divided stator module monomers with the same structure, adjacent stator module monomers are inserted, each stator module monomer comprises one winding portion, one splicing portion and one spacing portion which are integrally formed by punching, the inner side face of one splicing is one arc surface, one splicing portion is provided with one location hole, one side face of each splicing portion is provided with one convex tooth, the other side face of each splicing portion is provided with one concave tooth, two side of each convex tooth are respectively provided with semi-circular pin holes, the inner side face of each concave tooth is provided withtwo semi-circular pin holes, two adjacent stator module monomers are spliced, then the semi-circular pin holes of the convex teeth and the semi-circular pin holes of the concave teeth form two symmetrical pin holes with full-circular structures, and one pin is inserted in each pin hole. The block assembled stator punching structure reduces the waste rate of punching materials, achieves high-speedpunching of a progressive die, provides a punching module for automatic winding inserting, reduces labor intensity, improves production effectiveness and saves production cost.

Description

technical field [0001] The invention relates to the fields of automobile motors, driving and traction motors, household appliance motors, etc., and particularly relates to a block-assembled stator punching structure. Background technique [0002] The main components of the motor include the stator and rotor part of the motor. The structure of the stator is directly related to the performance of the motor. The traditional motor stator is as follows: Figure 4 The full-circle stator punching sheet shown has features such as lower line grooves and welding post holes on the punching sheet. Through the lamination of the special mold press machine, multiple punching sheets are stacked together, and the upper and lower pressure rings are reinforced. The welding post is welded and fixed to form the stator core, and then the wire is manually embedded in the slot; this traditional method has the following disadvantages, the production efficiency of the punching sheet is not high, high-...

[0002] The main components of the motor include the stator and rotor part of the motor. The structure of the stator is directly related to the performance of the motor. The traditional motor stator is as follows: Figure 4 The full-circle stator punching sheet shown has features such as lower line grooves and welding post holes on the punching sheet. Through the lamination of the special mold press machine, multiple punching sheets are stacked together, and the upper and lower pressure rings are reinforced. The welding post is welded and fixed to form the stator core, and then the wire is manually embedded in the slot; this traditional method has the following disadvantages, the production efficiency of the punching sheet is not high, high-speed punching cannot be realized, and the tonnage of the punching machine is required for the overall punching. ;When the punching sheet is large, the material waste rate is high, and there are many leftover materials for punching; the cost of manual off-line is high, and the physical exertion is large; it is difficult to realize automatic embedding, which is not conducive to automation
