Embodiment Construction

[0024] Next, an embodiment of the coil winding machine of the present invention will be described below with reference to the drawings. The coil winding machine of this embodiment is the same as the conventional example shown in the above-mentioned Patent Document 1, and is configured such that a flywheel 120 is rotatably provided outside the bobbin, and the flywheel 120 is inserted with a winding wire 400 forming a coil. 120 rotates around the bobbin at high speed, so that the winding wire 400 is helically wound on the bobbin that descends. Moreover, the coil winding machine of this embodiment is also provided with a height difference on the coil frame so that the circumference of the coil can be variably set, but it has the following characteristics: it is configured to obtain a large height difference stroke, and the height difference stroke is particularly Used for winding coils with different circumferences.

Abstract

An object is to provide a coil winding machine which makes it possible to increase the stroke of a winding frame piece without making the whole larger. A coil winding machine in which a stepped winding frame moves in the direction of the center axis of rotation as a flyer turns, whereby the winding frame is wound with coils on a plurality of steps to form coils different in perimeter. In this coil winding machine, a movable winding frame (10) has a stroke bar (13) formed with a cam groove, and pins extending through the cam groove on each step are fixed to a pair of racks (22, 22) disposed with the stroke bar (13) therebetween. Pinion gears (23, 23) mesh with the racks (22, 22) and have arms (24, 24) which are disposed with the stroke bar (13) therebetween and fixed to the gears (23, 23) such that the arms cross each other. Winding frame pieces (25A, 15B, 15C) are connected to the front ends of the two arms (24, 24) in such a manner as to hold the same attitude with respect to the operation of the arms (24, 24).

Description

technical field [0001] The present invention relates to a coil winding machine for manufacturing electric motors used in household electrical appliances, automobiles, etc., and more specifically, a device that provides a variable height difference on the coil frame in order to change the circumference of the coil , particularly relates to a coil winding machine configured to obtain a large height difference stroke. Background technique [0002] Conventionally, there has been proposed a coil winding machine for manufacturing electric motors in which a variable height difference is provided on the bobbin in order to change the circumference of the coil. For example, the technique described in Japanese Unexamined Patent Application Publication No. 2003-164122 cited as Patent Document 1. [0003] Coils for electric motors are wound helically on the bobbin of a coil winding machine, and then Figure 8 As shown in FIG. Tank 301 for transfer. However, when inserting and forming ...
