不可能であつた。[Conventional technology and its problems] Conventionally, when a stator coil for a small fan is used as an outer rotor type motor in a narrow space such as a cooling fan motor for a computer, it is necessary to minimize the gap between the stator coil and the rotor. is preferable in terms of characteristics. Such a stator coil is produced by molding the coil end after winding the magnet wire using a press or the like. However, the varnish treatment and heat treatment cause the coil end to swell and return to its original shape, a so-called springback, which increases the coil width. For this reason, when impregnating stator coils with varnish, it was necessary to perform curing at low temperatures for a long time, or to process the stator coils one by one by placing weights on the ends of the coils. As a result, it has been impossible to perform drip impregnation treatment with varnish with high quality and high productivity.

ある。[Means for Solving the Problems] The present invention is such that one end of the stator coil is introduced outside by penetrating the hollow part of the core part of the stator coil, and the flange part of the other end is brought into contact with the end surface of the core part. This stator coil chucking jig includes a bolt portion, and a nut portion that is removably fitted and fixed to the one end portion of the bolt portion via a ring-shaped spacer member.

向上及び生産性の向上を達成できる。[Function] According to the stator coil chucking jig according to the present invention, the stator coil is held by sandwiching both ends of the core part between the bolt part and the nut part, so the width of the coil end and the coil inner diameter are Various stator coils can be reliably held regardless of their size. By adjusting the wall thickness of the spacer member, various stator coils can be maintained in a constant state. Since the varnish drop impregnation process is performed in this state, it is possible to improve the quality of the varnish impregnation process and improve productivity.

FIG. 1 is an explanatory diagram showing the configuration of an embodiment of the present invention. This stator coil chucking jig has a thread groove 3 for screwing a nut portion 2 (to be described later) at one end of a shaft core 1 inserted into a hollow portion of a core portion of a stator coil as shown in FIG. It has a bolt part 5 with a collar part 4 formed on the other end. The diameter of the shaft core 1 may be any diameter as long as it can penetrate the hollow part of the stator coil, which is the object to be processed. After penetrating the stator coil, a nut portion 2 as shown in FIG. C is attached to and removed from one end of the bolt portion 5 via a ring-shaped spacer member 6 made of fluororesin or the like as shown in FIG. It is designed to fit freely. The wall thickness of the spacer member 6 is always constant for various stator coils with different coil end widths, and
It is desirable to set it appropriately according to the coil end width so that it can be clamped and fixed.

の下に実現することができる。 In the stator coil chucking jig 10 constructed in this manner, the core portion 12 of the stator coil 11, which is an object to be processed, is fitted into the axis 1 of the bolt portion 5, as shown in FIG. Next, the nut portion 2 is fitted to one end of the shaft core 1 via a spacer member 6 having a predetermined shape, and the stator coil 11 is held and fixed by the bolt portion 5 by screwing. In this way, since the stator coil 11 is held by holding both ends of the core part 12 between the bolt part 5 and the nut part 2, the stator coil 11 can be held securely regardless of the width of the coil end and the coil inner diameter. I can do it. Further, by adjusting the wall thickness of the spacer portion 6, various stator coils 11 can be maintained in a constant state at all times. As a result, varnish impregnation by dropwise impregnation treatment can be achieved with high quality and high productivity.
