A winding machine and winding method for double-outer enameled wire outlets of a motor

Abstract

The invention relates to a winding machine and a winding method for winding the outgoing wire of the double-outer-side enameled wire of a motor and belongs to the technical field of motor manufacturing. The mechanism is mainly designed with a split type winding core mechanism. When the winding is started, the length of a copper wire for one turn of a coil is reserved firstly. After that, a wire iswound on a winding core from left to right from the second turn, until the wire is wound by a preset number of turns. After that, the wire is wound from the right to the left. Repeated in this way, the wire is wound by a required number of layers. At this time, a handle is held to drive a sleeve to move backwards in the axis direction. Due to the fact that the position of a displacement groove islong, the distance between a left rotating shaft and the sleeve is increased by the length of one turn of the coil when a screw in a first positioning hole moves from a limit position at one side toa limit position at the other side. At this time, a main motor continues to rotate, and the first turn of a second coil is wound up. During the working process, two stations are arranged for the winding core, namely a locking station and a winding core withdrawal station, respectively. When the winding is completed, the winding core is enabled to rotate in the sleeve and retreat to the winding core withdrawal station. After that, the winding core exists from the coil.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a winding machine and a winding method for double-outside enameled wire outlets of a motor. Background technique [0002] The stator coil is a very important part of the motor. The existing coils are usually wound from left to right in turn, and the winding method is formed at one time. The formed coil is as attached Figure 8 As shown, the incoming wire head is located in the axial direction of the end of the coil, and the outgoing wire head is located in the radial direction of the circumference of the coil. This kind of coil structure makes the coil install in the process of installing radially or axially. The wire ends at the end of the coil always occupy the winding height of one turn of enameled wire, which causes a waste of installation space, is not conducive to reducing the overall height of the motor, and also has a negative impact on the electromagnetic perf...
