Description

one.

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

A device is known for laying a two-layer winding of baseless electric machines, made in the form of a mandrel on which the upper and lower layers of the winding sections are fixed with clamping elements, after which the winding 1 is braced.

A disadvantage of this device is its low productivity.

A device is known for making the winding of unspare-mounted koreas, containing its matrix, punch, and hollow cylindrical comb with a number of teeth equal to the number of winding sections of the core 2.

However, this device due to the high complexity when laying the closing winding sections has low productivity.

The purpose of the invention is to improve the performance of the device.

The goal is achieved by the fact that the device is equipped with an orienting rod installed in the central holes of the comb and punch, and the second hollow

a cylindrical comb mounted coaxially with the first, teeth facing one another, while the second comb is equipped with a drive for its rotation relative to the first one by a step of the winding.

FIG. Figure 1 shows a device for manufacturing the winding of the gas-free Koreas; in fig. 2 - the same, at the moment of turning. On the winding step.

The device for manufacturing baseless electric machines contains two hollow cylindrical combs 1 and 2 with a number of teeth equal to the number of winding sections of the core, die 3, punch 4 and orienting rod 5. Combs 1 and 2 are set counter-toothed and form

5 hollow cylinder. A punch 4 and a rod 5 are located coaxially to the inner surfaces of the tongue, knockers 1 and 2, ensuring coaxiality of the combs 1 and 2. A matrix 3 is mounted concentrically to the outer surfaces of the combs, fixed together with the rod 5 of the section 6 in the radial direction. In this case, the second comb 3 is connected with a drive (not shown) of its rotation relative to the first comb 1 by an angle equal to the step of the winding (Fig. 2).,

The device works as follows.

The slots of the pre-assembled device are placed in sections 6. In this case, the upper parts of sections 6 enter the slots of comb 2, and the lower parts of sections 6 enter the grooves of comb 1. The radial position of sections 6 is fixed with rod n 5 and matrix 3. Then The comb 2 (Fig. 2) is set on the winding core, the matrix 3 is retracted and, using the punch 4, the sections are shifted onto the comb 1 and pressed against its base.

The use of a device that provides for the layout and simultaneous laying of winding sections with a predetermined clamp, eliminates the laying operation of the closing winding sections, thereby reducing labor intensity and increasing productivity.
