Description

The invention relates to manufacturing equipment for the manufacture of electrical machines and can be used in electrical engineering.

The purpose of the invention is to increase the productivity and quality of manufacturing the coil groups by combining the operation of winding, forming and laying the plates.

Fig. 1 shows an apparatus for manufacturing coil groups; figure 2 is the same, side view; fig.Z - technological scheme of winding; Fig. 4 shows a coil group of an electrical machine; figure 5 is the same, top view; 6 shows a coil group of conventional electric machines; 7 - the same, side view; Fig. 8 is a kinematic diagram of the device; Fig. 9 shows the assembly with plate holders for face machines; FIG. 10 is the same side view; Fig. 11 illustrates the assembly with plate holders for traditional machines; on Fig - the same, front view.

The device comprises a housing 1 with a mandrel rotating therein. The winding of the wire 3 and the laying of the ferromagnetic plates (elements) 4 is performed on the template 5 using the plate-laying machines or plate-holders 6 holding the elements 4 using the plate springs 7. The template 5 has longitudinal slots or grooves 8 , made with a radius of curvature corresponding to the bore of the stator. Plaster holders 6 are installed in the slot x 8. To fix the plate holders 6 in the initial position, the pawls 9 are mounted on the axis 10 in the drum 11, mounted rigidly on the mandrel 2. The springs 12 are used to return the plate laying 6 with the plates 4 to the working position 9, and the springs 13 on the dogs 9. on housing 1, they are used to turn the levers 15 through the rods 16.

The device works as follows.

The device is mounted on serial winding walls with the technological winding scheme shown in FIG. Wire 3 from reel 17 through rollers 18 leash

and the tensioning mechanism rollers 19 are loaded onto the conductor 20 and then onto the template 5. With this device, two types of coil groups can be wound: for

front electric machines (FIGS. 4 and 5) and for traditional electric machines (FIGS. 6 and 7). The winding is performed on the template 5. The layout of the ferromagnetic elements 4 is as follows: from

the signal from the controller (not specified), the electromagnet 14 is triggered, which moves the lever 15 through the tu 16. The doggie 9 rotating together with the sliding template 5 rolls onto the lever 15,

releases a series of fixed plate holders 6 with ferromagnetic elements 4 and using springs 12 they are laid within one turn of the template 5. The next turn of the wire already presses the ferromagnetic element 4. After the next layers of wire are laid, the cycle repeats.
