Jl: ioCip (depends on the technology of manufacturing electric machines and can be used in electrics (; hichne:; which and automotive industry).

The purpose of the invention is to increase productivity.

The drawing shows the proposed device, axonometric.

The device contains an unwinding device 1 for unwinding and creating the necessary technological tension of the wire, winding the head 2 with the spindle 3, the guide roller 4 to wind and lay the turns, the roller 5 to pull the wire between the coil groups, ring 6 with the fixtures 7 and the cartridge 8 for installing the stator pack 9. The ring 6 passes through (the hole in the cartridge 8 and the bore of the stator 9 and is rotatably fixed around the axis (1, perpendicular to the axis of the cartridge and the stator pack 9). TO ldo has PA- Disi; nuyu slit allowing the establishes a stator pack and withdraw the cartridge from the beginning and at the end of the winding chuck 8 provides Powo,.

The mouth of the stator package 9, matched with the double ring of the ring 6. In order for the slot in ring 6 to install and remove the stator package 9 at the beginning and at the end of the winding, the number of mandrels 7 must be a multiple of the coils in the stator. For example, for a winding containing 18 coils, the ring is made with 6 mandrels.

The required length of the inter-bead joint is provided by the distance between the mandrels 7 on the ring 6. When calculating the dimensions of the ring 6, the length of the inter-cone joints and the specific dimensions of the coils 7 as well as the layout of the winding are taken into account.

Roller 5 pulls off the wire between the mandrels 7 after winding each roll group. The resulting loop is cut after the winding has been laid, forming a different output.

In the cartridge 8, there is a mechanism for transferring the coils to the groove, which is made in the form of pusher levers 10.

The device works as follows Im in the image.

1 and with the necessary tension is fed into the winding head 2, the spindle 3 of which carries out a rotational movement, winds the wire on one of the mandrels 7 located on the ring 6 behind the slot. When this coil is finished winding, the ring 6 is rotated, the mandrel with the coiled winding moves to the next position and the second coil is wound onto the second mandrel, then the third, and so on. At that moment, when one third of the wire pulls under winding, the slot 6 of the ring 6 is positioned so that the stator package 9 can be installed in the cartridge B.

After installing package 9, the next rotation of ring 6 takes place and

0, the fourth mandrel 7 rises under the winding. The first mandrel at this time is located opposite the stator slots 9. Thus, the winding of the coil on the fourth mandrel 7 occurs simultaneously with the transfer of the coil from the first mandrel 7 into the grooves of the stator pack 9. Then a coordinated rotation of the ring occurs 6 and chuck 8 with stator 9 and coil winding is performed.

0 on the fifth mandrel 7 and the simultaneous transfer of the coil with the second mandrel 7 into the grooves of the bag 9 and so on until all the coils of the winding have been wound and laid. In this case, after winding the coils constituting the coil group, roller 5 pulls the wire from the last coil of the first coil group to the first coil of the second coil group. As a result, after stacking the coils into a stator pack, wire loops are produced, which are cut to obtain phase leads.

The manufacturing process of the stator winding is completed when

 ring 6 is set to its original position, allowing you to remove the coiled stator 9 from the cartridge 8 and install the next stator package. Next turn the ring 6 into the bore

0, a package of stator 9 is fed to a mandrel 7 with a pre-wound coil, and the winding process is repeated.
