Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for inserting windings and wedges into slots fitted into a rotating electric machine core.

The rotating electric machine core is composed of stacked core plates.
There are two types: one in which the slots are stacked parallel to the axis, and the other in which the slots are stacked at a slight angle to the axis.

When inserting windings and wedges into the slots of a rotating electric machine iron core, if the slots are parallel to the axis of the iron core, an insertion device compatible with this has been developed and used. Scratched items cannot be inserted using traditional insertion hawks and are generally done by hand.Therefore, to help improve efficiency, inserting them into simulated slots is not possible. It has been desired to develop an insertion device capable of inserting windings and wedges. It is a device for ``a plurality of winding guide blades or a plurality of windings that are slanted and stood on a base so as to fit into the slots swung in relation to the contact of the rotating electric machine iron. A wedge guide for guiding a wire guiding blade and a plurality of winding wedges, a driving rod that is movable back and forth in the axial direction of the rotating electrical machine iron core, and a driving rod that is mounted on the driving rod so as to be rotatable around its longitudinal axis. a winding pressing inserter support and/or a wedge pressing inserter supporting tool, each of which is tilted along the plurality of blades and the plurality of wedge guys W so as to be able to swing freely around the outer periphery of the supporting tool; It consists of a plurality of supported winding pressure inserters and/or a plurality of wedge pressure inserters, so that windings and wedges can be easily inserted.

Embodiments of the winding and wedge insertion device according to the present invention will be described below with reference to the drawings. In Figure 1, 1
1 is an iron core of a rotating electric machine, and a slot 2 for accommodating a winding and a wedge is provided in the inner circumference of the iron core 1, and the slot 2 is modeled with respect to the center of the iron core 1. The wedge is used to prevent the winding from protruding from the slot closing portion after being inserted into the slot, or from coming into contact with the iron core 1. A slot insulating member 3 is fitted into the inner wall of the slot 2 before the winding and the wedge are inserted.

FIG. 2 shows a state in which the winding 4 has been previously inserted into the winding and wedge insertion device.

Reference numeral 5 denotes blades for guiding the windings, and the number of blades 5 is the same as that of the slots 2 of the rotary electric machine core 1 and is tilted and stands on the base 6 so as to fit into the simulated slots 2 of the rotating electric machine iron core 1.

Numeral 7 is a wedge guide for guiding the windings and wedges, and like the blade 5, the same number of wedge guides as the slots 2 are erected on a base 71 at an angle.

The winding 4 is previously fitted into a predetermined position, and the wedge 8 is fitted below the winding 4. 3 and 4 show the initial and immediate states when the winding 4 and the wedge 8 are inserted into the slot 2 of the rotating electric machine core 1 by the insertion device.

The rotating electric machine iron core 1 is located above the winding 4 and is fitted into the middle part of the plate 5. Reference numeral 9 denotes a drive rod, which is provided so as to be movable in the axial direction by a drive device (not shown).

A wire-wound press inserter support member Q is attached to the tip of the drive rod 9 so as to be rotatable around the longitudinal chest D of the drive rod 9, and a wedge press inserter support member 1 is attached to the middle part of the drive rod 9. Like the winding press inserter support vine 0, the vine is rotatably attached. 12 is a winding press inserter for press-inserting the winding 4, and is connected to the slot 2 of the iron core 1. As shown in FIGS. 5 and 6, the same number of blades are arranged in an inclined state with respect to the center of the drive rod 9 so as to follow the plurality of oblique blades 5. It is swingably supported through a pin 13, and its wing-shaped tip 14 protrudes into the gap between adjacent flades.

The shaft 5 is a wedge pressing inserter for press-inserting the wedge 8, and the same number of slots 2 as the slots 2 of the iron core 1 are driven along the plurality of inclined wedge guides 7 in the same way as the winding pressing inserter 12. The rods 9 are tilted with respect to the axis thereof, and are swingably supported on the outer periphery of the wedge press inserter support 11 via pin hooks 6. 17
is a winding pressing inserter cap, which is fixed to the supporting member 10 after the winding pressing inserter 12 is assembled so as to rotate together with the winding pressing inserter support IQ.

In this embodiment, a blade for guiding the winding and a wedge guide for guiding the winding wedge are shown as an example, but it is also possible to use only the blade for guiding the winding, and the winding pressing inserter 12 and the wedge guide for guiding the winding are shown. As shown in FIG. 3, the wedge pressing inserts 15 are separated into upper and lower parts, but a pair of wedge press inserts located above and below the drive rod 9 may be integrated. It is also possible to use only one of them alone.

Further, in this embodiment, the winding press inserter 12 and its supporting odor 10 and the wedge press inserter 15 and its supporting odor 1
Although the connection method 1 is exemplified as using the pins 3 and 16, it can also be done without using pins or with protrusions other than pins in place of the pins. Next, the operation of this insertion device will be explained.

When the winding 4 and the wedge 8 are inserted, as shown in FIGS. 3 and 4, the drive rod 9 is first moved upward by a drive device (not shown), and the winding pressing inserter The support rods 10, 11 for the wedge press inserter and the wedge press inserter are pushed up together with the drive rod.
The winding press inserter 12, the wedge press inserter 15, and the cap 17 supported by the coil presser 1 move upward. In that case, the slot 2 of the rotating electric machine core 1 is deep, and the blades 5 and wedge guides 7 are installed obliquely as shown in Figures 2, 5, and 6 to accommodate the runout. The opposing surfaces of each pair of adjacent blades 5 are parallel at any position, and the drive rod 9 of the parallel opposing surfaces
The distance from the center varies depending on the vertical position of the blade.

On the other hand, as described above, the winding press inserter support 10 is rotatably attached to the tip of the drive rod 9, and the winding press inserter 12 is swung in an inclined state along the inclined blade 5. The pin 13 is movably supported, so that as the drive rod 9 moves up and down, the position of the pin 13 moves around the rod 9, and the winding press inserter support 10' is also spread. At this time, the winding press inserter 12 swings about its support pin 13 as a fulcrum. Further, as described above, the wedge pressing inserter support member I1 is rotatably attached to the middle part of the drive rod 9, and the wedge pressing inserter 15 swings in a tilted state along the oblique blade 5. Since it is freely supported, as the drive rod 9 moves up and down, the wedge press inserter support 11 also rotates in the same way as the winding press inserter support 10, and the wedge press inserter 15 also rotates with respect to its support odor 11. It swings about the pin 16 as a fulcrum.

Therefore, the winding 4 and the wedge 8 are placed inside the simulated slot 2.
is inserted smoothly. In the winding and wedge insertion device according to the present invention, as described above, the supporting rods for the winding pressing inserter and the wedge pressing inserter are rotatably provided on the drive rod, and the winding pressing inserter and the wedge pressing inserter are rotatably provided on the drive rod. Since the pressure inserters are swingably attached to their supports, windings and wedges can be easily and smoothly inserted into the swung slots of the rotating electric machine core.
The insertion work, which used to be done manually, can be mechanized, which has the effect of improving efficiency.
