Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a conductor supplied from a flyer that swivels by holding an armature core horizontally from both sides of an axis to cover an outer surface other than a winding part. The present invention relates to a winding chuck of a winding machine that introduces a wire into a required slot.

[Conventional technology]

In a winding machine that winds a conductor wire supplied from a rotating flyer around an armature core, a winding chuck that horizontally holds the armature core to be wound from both sides of the axis is fixed so that it cannot rotate. Some of them are swingable, and some of them are swingable and their postures are regulated in a predetermined direction by their own weight.

The former has a complicated structure and the winding machine becomes larger and heavier, while the latter has a simple structure and the winding machine is small and lightweight and has good workability. The latter is used exclusively for the winding of the child.

This invention relates to the latter winding machine.

First, an outline of a double drive winding machine, which is a typical model of this type of winding machine, will be described.

An armature before coil winding, in which a laminated core and a commutator provided at a distance from the laminated core are fixed on the same axis, is a collet of a winding machine with the axis of the commutator side being horizontal. It is gripped and fixed by.

On both sides in the horizontal direction across the axis of the fixed armature,
A support shaft is provided which is orthogonal to the axis line and approaches or separates from each other, and a pair of winding chucks are slidably attached to the tip ends of the support shafts.

These winding chucks have a vertical balance weight attached to the bottom to prevent tilt in the vertical direction, and a horizontal balance weight attached to prevent tilt in the armature axis direction to control the winding chuck's posture by its own weight. Flyers for supplying conductors are pivotally mounted on the supporting shafts of the flyers.

Then, during winding, prior to the flyer's turning, the respective support shafts move in a direction in which they approach each other, and a pair of winding chucks sandwiches the outer surface of the armature core from both sides, while holding the armature stably, It serves to guide the lead wire supplied from the flyer that swirls over the slots other than the winding portion to the required slot of the armature core.

In addition, a winding guide is provided on the winding chuck in accordance with the axial length of the armature core, which is usually called the stacking thickness,
The lengthwise end face of the iron core is covered so that the winding is not caught on the end face of the slot insulating paper.

Generally, regardless of the stacking thickness of the armature core, the distance between the commutator side end face of the core and the commutator is regulated to a predetermined ground for the convenience of connection, so the commutator side provided on the winding chuck The winding guide is fixedly provided at a predetermined position, and only the other winding guide is movably provided depending on the stacking thickness.

[Problems to be solved by the invention]

However, in the winding chuck of such a conventional winding machine, vertical and horizontal balance weights for controlling the posture in the vertical and armature axis directions are fixedly provided,
Since it is adjusted for a specific length of armature core,
When winding an armature core with the same outer diameter but different stacking thickness, reassemble the winding chuck or install a movable side winding guide so that it can move in the axial direction of the armature by screw drive, etc. If the guide loses its balance and tilts, change the balance weight,
I had to rebalance by supplementing additional balance weights.

The former requires a large number of man-hours and various kinds of members corresponding to each length of the armature core for reassembly, and the latter requires a great deal of time to find an appropriate balance weight. It was

The present invention solves such a conventional problem, and when winding an armature core having the same outer diameter but different stacking thickness, the movable side winding guide is simply moved in accordance with the stacking thickness to achieve balance. An object of the present invention is to provide a winding chuck for a winding machine that does not need to be retaken.

[Means for solving problems]

Therefore, the winding chuck of the winding machine according to the present invention is mounted so as to be swingable around the axis of the lead wire supplying flyer orthogonal to the axis of the armature core fixed with the axis horizontal, and to be vertically and horizontally aligned. In the winding chuck of the winding machine, the posture of which is controlled by the balance weight of the armature core so as to sandwich the armature core from both sides of its axis and to cover the outer surface other than the winding part, at both ends of the armature core in the axial direction. Between the plates provided on the plate, a feed screw with a right-hand thread on one side and a left-hand thread on the other side is rotatably supported from approximately the center in the longitudinal direction parallel to the axis of the plate. A slider that integrates the winding guide that should move in the axial direction according to the stacking thickness of the armature core, and a nut that integrates the balance weight in the other threaded portion are screwed to prevent displacement in the rotational direction. Suitability , The pitch ratio of the right-hand thread portion and the left-hand thread portion is made inversely proportional to the ratio of the weight of the slider integrally formed with the winding guide and the weight of the nut integrally formed with the balance weight. By rotating the feed screw, the winding guide and the balance weight are moved in opposite directions.

[Action]

With the above structure, the vertical and horizontal balance weights fixed to the winding chuck are kept in the initial state, and the unbalance caused by the movement of the winding guide in the axial direction is Since it is completely canceled by the movable balance weight that moves in the opposite direction in response to the movement, it is possible to eliminate the trouble of rebalancing when winding the armature cores having different stacking thicknesses.
