Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coil manufacturing frame for manufacturing randomly wound coils used in electrical equipment such as motors.

[Conventional technology]

2. Description of the Related Art Conventionally known winding frames are shown in FIGS. 5 and 6, and are made of wood, synthetic resin, etc. and are attached to the spindle of a winding machine to wind conductive wire to produce a coil.

The figure shows a winding frame for producing a so-called two-strand coil in which two coils are connected. 1 is the spindle of a winding machine, which has a rectangular cross section and a step at the base end and has a body surface 1a. and has a threaded portion 1b at the tip. Reference numeral 2 denotes a winding frame, each of which has a cylindrical spacer 3 that is removably fitted to the spindle 1, and two approximately rectangular thick plates each having a step on the outer periphery and a part of the outer periphery formed in a tapered shape. reel drum 4
a+4b, a square plate-shaped side plate 5, and a spacer 6, and these members are fixed to the spindle 1 by a nut 7 screwed into the threaded portion 1b, so that the outer periphery of the winding frame drums 4a, 4b is fixed to the spindle 1. Winding grooves 8a, 8 on top
b is formed.

The winding frame 2 is fixed to the spindle 1 as described above, and the spindle 1 rotates a predetermined number of times to wind up the conductor. #8a, 8
The spindle 1 stops after winding it up into a coil shape. The wound coils are tied together in each winding groove, and the winding frame drum 4a is assembled.

After being extracted from the spindle 1 together with 4b, it is removed from the winding drums 4a and 4b, and the manufacturing of the coil is completed.

[Problem to be solved by the invention]

By the way, in the conventional winding frame 2, the winding frame drum 4a.

To remove the coil wound on winding frame 2
The entire assembly must be removed from the spindle 1 and each member must be taken apart to take out the coil. To manufacture the next coil, it is necessary to reassemble the winding frame 2 and attach it to the spindle 1.

As described above, there is a drawback that the reel frame must be disassembled and reassembled, which requires a considerable amount of time.

It is an object of the present invention to provide a winding frame for coil manufacturing, which eliminates the need to remove and disassemble the winding frame from a spindle each time a coil is manufactured, and allows setup for manufacturing the next coil to be made in a short time.

[Means to solve the problem]

In order to achieve the above object, this invention provides a winding frame for coil production that is attached to the spindle of a winding machine and is used to form a coil by winding a conductive wire a predetermined number of times in a winding groove provided on the outer periphery. a plurality of guide shafts protruding radially on the outer periphery of a boss that is removably fitted to the spindle; one end of each of the plurality of guide shafts is fitted and supported so as to be movable in the axial direction; A plurality of winding pieces having the winding grooves in the circumferential direction on an outer surface extending in the axial direction are fitted to the spindle so as to be movable in the axial direction, and guide the other ends of the winding pieces based on the movement. A winding frame comprising a slide ring connected to the winding piece through a link mechanism for moving in the axial direction of the shaft, and a fixing means for fixing the slide ring at a predetermined position on the spindle. shall be.

[Effect]

By fixing the slide ring, the winding piece is set in an appropriate position and a winding groove with an appropriately sized outer periphery is formed. After winding the conductive wire in the winding groove, by moving the slide ring in the axial direction, the outer diameter formed by the winding piece is narrowed to be smaller than the inner diameter of the coil. The coil can thus be removed from the winding frame without removing the winding frame from the spindle.

〔Example〕

FIG. 1 and FIG. 2 show an embodiment of this invention.
Components common or identical to those in FIGS. 5 and 6 are designated by the same reference numerals.

In FIGS. 1 and 2, the winding frame 2 is fixed to the spindle 1 and is in a state of being coiled.

Numeral 11 has a suitable length, one end forms a face plate 11a, and is removably fitted into the spindle 1. Numeral 12 is a boss welded to the outer circumference of boss 11 and extends radially. 13 is a retaining pin that is removably fixed to the tip of the guide shaft 12, and 14 is a slide ring that fits into the spindle 1 on the outside of the boss 11 so as to be slidable in the axial direction. 15 are provided in the same number as the guide shafts 11, one end of each is slidably fitted to the guide shaft 11 in the axial direction of the guide shaft 11 via the engagement hole 15a, and extends along the axial direction of the spindle 1. 2 running circumferentially on the outer surface
This is a winding piece in which winding grooves 8a and 8b are formed side by side. 16 is a link plate having both ends movably connected to the slide ring 14 and the winding piece 16 and serving as a link mechanism; and 17 is a link plate having one end fixed to the face plate 11a and the winding piece 16.
A guide rod 18 extending along the spindle 1 is a spacer that is removably inserted into the spindle 1. Further, the nut 7 is used as a fixing means for fixing the slide ring 14 in a predetermined position.

In the above configuration, the winding piece 15 is fitted onto the guide shaft 12 and is connected to the winding piece 15 through the boss 11 into which the pin 13 is inserted to prevent removal, and the link plate 16. The slide ring 14 is inserted into the spindle 1. Then, by inserting the spacer 18 and moving one end of the winding piece 15 to an appropriate position on the guide shaft 12 while tightening the nut 7, the boss 11 is brought into contact with the shelled surface 1a, and the space between the boss 11 and the spacer 18 is The slide ring 14 is fixed, the link plate 16 stands upright on the slide ring 14, and the winding piece 15 is placed in the winding position.

Therefore, the spindle 1 is rotated at a predetermined number of revolutions while feeding the conducting wire into the winding frame, and coil winding is performed to wind the conducting wire in the winding grooves 8a and 8b, and the coil 1 is placed on the winding frame 2 as shown in FIG.
0 is formed, and this coil 10 is bound with a binding member 10a such as tape or string.

Thereafter, the nut 7 and spacer 18 are removed, and the slide ring 14 is moved in the axial direction while moving the end of the winding piece 15 that fits with the guide shaft 12 toward the boss 11.
When the link plate 16 is tilted, each winding piece 15 is
approaches the spindle 1 side, and its outer diameter becomes smaller than the inner diameter of the coil 10. The coil 10 is then taken out from the winding frame 2.

To wind the next coil, simply insert the spacer 18, tighten the nut 7 to fix the slide ring 14, and return the winding piece to the above-mentioned state shown in Fig. 1 (very easily and in a short time). I can make arrangements.

〔Effect of the invention〕

According to this invention, a plurality of guide shafts protrude radially on the outer periphery of a boss that is removably fitted to a spindle of a winding machine, and one end of each of the plurality of guide shafts is movable in the axial direction. a plurality of winding pieces that are fitted and supported and have the winding grooves in the circumferential direction of the outer surface extending in the axial direction of the spindle, and are fitted to the spindle so as to be movable in the axial direction,
and a slide ring connected to the winding piece via a link mechanism that moves the other end of the winding piece in the axial direction of the guide shaft based on the movement, and the slide ring is placed at a predetermined position on the spindle. Since the winding frame is configured with a fixing means for fixing, the coil formed on the winding frame by winding the conductive wire can be taken out from the winding frame without removing the winding frame from the spindle and disassembling it. In addition, the winding frame can be set to the winding standby state simply by tightening the nut and fixing the slide ring. Therefore, removal of the coil from the winding frame and setup for the next coil winding can be performed extremely easily and in a short time.
