Abstract

The invention relates to the technical field of stator coil processing, in particular to an automatic wire expanding mechanism for a motor stator coil. An automatic wire expanding mechanism for a motor stator coil comprises a conveying frame used for conveying a workpiece disc, the conveying frame penetrates through a wire expanding support, a mounting plate at the upper end of the wire expanding support is a through hole, and a jacking mechanism used for jacking the workpiece disc and placing workpieces in the workpiece disc is mounted in the wire expanding support. The motor stator coil automatic wire expanding mechanism is mainly composed of a conveying system, a positioning wire expanding system and a grabbing system, a conveying frame serves as a core conveying component, and workpiece disc conveying is achieved by penetrating through a wire expanding support through penetrating type design; the jacking mechanism arranged in the wire expanding support can accurately lift the workpiece disc and the workpieces in the workpiece disc; the top plate at the top is integrated with the grabbing mechanism, the grabbing action of the stator coil is completed through up-and-down cooperative movement, all the parts form a closed-loop working system through hierarchical assembly, and the automatic process of conveying, positioning, wire expanding and grabbing is achieved.
