[0039]
Next, the winding operation of the winding device 1 will be described.
[0040]
First, the wire W from the wire supply source is pulled out from the nozzle 43 through the guide hole 32 of the head 31 and the guide hole 33 of the flyer 5 through a tension device (not shown), and the end of the wire W is held by a clamp.
[0041]
Subsequently, the rotor shaft 8 is held by the chuck 15 and supported. At this time, the rotational position is adjusted so that the slot 10b opens with respect to the side former 61 when the rotor 9 is wound.
[0042]
Subsequently, the workpiece support 12 is raised, and the rotor 9 is held at a position where the wire W is wound around the terminal 6 via the flyer 5. And the operation | work which ties the wire W to the terminal 6 by performing operation | movement of (1)-(4) is performed.
[0043]
{Circle around (1)} As shown in FIGS. 2A and 2B, the flyer 5 is rotated forward to stop, and the wire W is hooked on the opposite core side (upper side) of the terminal 6. At this time, the commutator cover 20 is held away from the commutator 7 so as not to disturb this operation. The side former 61 and the center former 51 surround the core 10 so that the wire W is not caught on the core 10.
[0044]
(2) As shown in FIG. 3, the commutator cover 20 is lowered and moved backward to hold the commutator 7 in a position that covers it.
[0045]
{Circle around (3)} As shown in FIGS. 4A and 4B, the flyer 5 is reversely rotated to stop, and the wire W is hung on the core side (lower side) of the terminal 6. At this time, the commutator cover 20 guides the wire W drawn from the nozzle 43 to the lower side of the terminal 6 by sliding on the inclined guide surface 20a and the orthogonal guide surface 20b.
[0046]
(4) As shown in FIG. 5, the commutator cover 20 is moved forward and lifted away from the commutator 7, and the terminal 6 is exposed facing the flyer 5.
[0047]
The operations of (1) to (4) are performed once or a plurality of times, and the work of tying the wire W to the terminal 6 is completed. Next, the operation | movement of (1)-(6) is performed and the operation | work which winds the wire W around the predetermined teeth 10a is performed.
[0048]
(1) The work support 12 is moved, and the rotor 9 is held at a position where the wire W is wound around the teeth 10 a via the flyer 5.
[0049]
(2) The head 31 is advanced toward the rotor 9 and the center former 51 is brought into contact with the outer peripheral surface of the core 10.
[0050]
(3) Each side former 61 is moved, and each side former 61 is brought into contact with the outer peripheral surface of the core 10. Thereby, the core 10 is held and supported by each side former 61. In this state, a predetermined slot 10 b around which the wire W is wound is opened between each side former 61 and the center former 51.
[0051]
(4) Open the chuck 15 and move the work support 12 to hold the chuck 15 away from the rotor shaft 8 so that the chuck 15 does not interfere with the flyer arm 42 and the like.
[0052]
(5) The commutator cover 20 is lowered and moved backward to hold the commutator 7 at a position covering it. This prevents the wire W from being caught on the commutator 7 or the terminal 6 during the winding operation.
[0053]
Note that the operations (2) to (5) are not necessarily performed in this order, and can be performed simultaneously, for example.
[0054]
(6) In the state where the core 10 is supported by the side formers 61 and the center former 51 in this way, as shown in FIG. 6 and FIG. It is wound around a predetermined tooth 10a.
[0055]
Thus, after winding the wire W around the teeth 10a a predetermined number of times, the elevating cylinder 19 raises the work support base 12, and the rotor shaft 8 is again gripped and supported by the chuck 15. Subsequently, after each side former 61 and the center former 51 are separated from the core 10, the index motor 13 is driven to adjust the rotational position of the rotor 9. Subsequently, the rotor 9 is held at a position where the wire W is wound around the terminal 6 via the flyer 5, and the wire W is bound to another terminal 6 by performing the operations (1) to (4). Do work.
[0056]
The winding operation for one pole is completed by the series of operations described above, and the winding operation for each pole is performed by performing the same operation. When the work of tying the wire W to all the terminals 6 is completed, the wire W is held via the clamp, and the wire W extending from the terminal 6 is cut via a cutter (not shown). Finally, the rotor 9 is removed from the chuck 15 and the winding operation is completed.
[0057]
The operation of linking the wire W to the terminal 6 configured as described above is performed by rotating the flyer 5 forward with the terminal 6 exposed from the commutator cover 20 to bring the wire W toward the anti-core 10 side of the terminal 6. A step (1) for hanging, a step (2) for moving the commutator cover 20 to cover the terminal 6, a step (3) for reversely rotating the flyer 5 and hanging the wire W on the core side of the terminal 6, and a commutator cover 20 Step (4) of exposing the terminal 6 is performed.
[0058]
This eliminates the need to move the flyer 5 by moving the heavy head 31 up and down during the work of tying the wire W to the terminal 6, thereby saving labor. The winding device 1 does not require a mechanism for moving the head 31 up and down with respect to the gantry 2 and simplifies the structure.
[0059]
The operation of winding the wire W around the teeth 10a is a step (1) in which the core 10 is gripped and supported by the side formers 61 and the center former 51 and separated from the rotor shaft 8 so that the chuck 15 does not interfere with the flyer arm 42 and the like. (4), the step (5) in which the commutator cover 20 covers the terminals 6, and the step (6) in which the flyer 5 is rotated and the wire W fed from the nozzle 43 is wound around the teeth 10a.
[0060]
As a result, the flyer arm 42 and the like rotating around the core 10 do not interfere with the chuck 15, and the track of the nozzle 43 can be arranged in the vicinity of the rotor shaft 8, and the wire W can be moved from the back of the slot 10 b. The space factor of the wire W can be increased by winding without gap.
[0061]
The track of the nozzle 43 may be disposed on the side opposite to the flyer 5 beyond the axis of the rotor shaft 8. In this case, since the wire W wound around the teeth 10a is wound while being pressed against the inner part of the slot 10b by the tension, the space factor of the wire W can be effectively increased.
[0062]
Further, by performing the winding work while delivering the core 10 between each side former 61 and the chuck 15, it becomes possible to continuously wind the wire W of each pole around the core 10 and increase the productivity. It is done.
[0063]
The present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within the scope of the technical idea.
