Wire cutting device of stator winding machine

Abstract

The invention belongs to the field of motor production and manufacturing and particularly relates to a wire cutting device of a stator winding machine. The wire cutting device comprises a fixed base block and a pressing block. A cutter is disposed on the base block. The pressing block moves in a reciprocating manner and is used for dragging an enameled wire to the cutter for cutting and tightly pressing the enameled wire to the base block. The moving direction of the pressing block is parallel with pointing direction of the edge of the cutter. A groove directly facing the cuter is formed in the pressing block, and cutting is completed by the meshing and separation of the cutter and the groove. The wire cutting device has the advantages that manual wire cutting by a worker after plastic package stator winding is not needed, the worker does not need to pull the wire during winding of the next stator, and the worker does not need to manually rewinding the loosened wire after plastic package stator winding is completed.

Description

technical field [0001] The invention belongs to the field of motor production and manufacturing, and in particular relates to a wire cutting device of a stator winding machine. Background technique [0002] The prior art provides an automatic winding machine with a plastic-encapsulated semi-stator. Its main structure includes a winding reel, the enameled wire passes through the edge of the reel, and there is a device behind the reel for driving the enameled wire to slide along the edge of the reel. When winding the wire, you only need to fix the half-stator iron core with a clamp at the position facing the center of the winding reel, then wind the end of the enameled wire on the half-stator iron core, and finally start the winding machine. Realize the automatic winding of the enameled wire. After the winding is completed, the enameled wire should be cut off to remove the stator, and then the next stator should be wound. In the prior art, manual operation is still used to cu...

AI Technical Summary

Problems solved by technology

In the prior art, manual operation is still used to cut the enameled wire. The disadvantages of manual cutting are: first, because the enameled wire is in a tight state before being cut, the enameled wire will rebound rapidly at the moment of cutting, which will make the end of the stator winding The phenomenon of loose wire occurs. Secondly, after the enameled wire is cut, the operator has to pull the enameled wire lead on the winding machine and wait for the next stator to be wound, which consumes manpower and affects production efficiency.
