Winding machine and winding method

Abstract

The invention provides a winding machine and a winding method. When the winding the performed on the first layer and the second layer, a top end of a side plate completely enters into the inner circumferential side of a magnetic pole and the wire is stably and regularly wound on the magnetic pole. The winding machine comprises: a flying fork capable of rotating around the magnetic pole of multi-pole armature and simultaneously leading out the wire and winding the wire relative to the magnetic pole; a pair of central winding molds configured to axially clamp the magnetic pole from the multi-pole armature and guide the wire led out from the flying fork to the magnetic pole; a pair of side plates configured to axially clamp the magnetic pole from the multi-pole armature and guide the wire led out from the flying fork to the magnetic pole. The pair of the side plates are configured to incline relative to a rotation shaft of the flying fork in the way of closing to the inner circumferential side of the multi-pole armature and change the inclined angle relative to the rotation shaft of the flying fork, therefore the top interval between the inner circumferential side of a magnetic pole and the side plate is changed.

Description

technical field [0001] The present invention mainly relates to a winding machine and a winding method for winding a wire for forming a coil on a multi-pole armature. Background technique [0002] Conventionally, in order to wind a wire for forming a coil on a magnetic pole of a multi-pole armature, a flyer-type winding machine having a flyer that draws out the wire while rotating around the magnetic pole and winds it around the magnetic pole has been widely used. wire. Moreover, in order to achieve better performance with the limited size of the armature such as a motor, it is required how the winding machine can perform more windings in the limited winding space of the multi-pole armature. In this regard, it is effective to wind adjacent wires neatly around the magnetic poles without gaps, that is, so-called neat winding. Therefore, the following flying fork type winding machine is known, comprising: a pair of central winding dies, which are configured to clamp the magnet...

Problems solved by technology

Then when wanting to continue to wind the second layer on the first layer winding that has been wound on the magnetic pole 201, the top of the side plate 202 will be in contact with the first layer, so that when the second layer winding is carried out, it cannot be used. The side plate 202 enters the inner peripheral side of the magnetic pole 201

And when it is desired to carry out the third layer of winding, the top of the side plate 202 will also be in contact with the second layer, so that the distance for the side plate 202 to enter the inner peripheral side of the magnetic pole 201 becomes shorter

In this way, along with the winding of the upper layer, the entry distance of the side plate 202 will be shortened successively, thereby leaving the problem that the inner peripheral side cannot guide the wire to the part where the winding is originally intended to be performed in the winding of the upper layer. topic
