FIELD: engines and pumps. SUBSTANCE: proposed device comprises housing 1 tetrahedron-like to part 2 and lower part 3 representing casing cut on its both sides, both said parts being separated by shoulder 4.

The invention relates to a device for the manufacture of coils, in particular for laying the conductors of the winding inside the open grooves of the rotors and stators mainly power electrical machines. It is known device for pulling conductors of the winding in the core of the rotor of the engine containing the plate thickness corresponding to the size of the groove (U.S. Pat. DE No. 19521669, publ. 04.1996 year). The bottom rim of the plate has at the ends of the cuts. The lateral surface of the plate with a vertical shock stamps with active bottom ends that communicate with the upper edges of the slots. The conductors located in the groove, due to the vertical displacement of the tool inside of the groove is compressed active lower ends of the shock stamps, buying elliptic cross-section. After compression of the wires percussion stamps perform point compression of the upper edges of the grooves, forming an internal ledge, carefully locking the extreme Explorer. In the windings of rotors or stators powerful electric machines the length of the core and, consequently, the groove is considerably greater than the length of the known devices, the reels are provided with a ventilation channels, and the conductors of the coils have a flat shape. When the conductors are fixed elastic strips and slot wedges complex profile to prevent slipping p is Vodnikov under the influence of centrifugal forces. In addition, the grooves has a complex profile in the upper part, providing intimate contact of their inner surfaces with the outer surfaces of the slot wedges. When laying the conductors of the winding in the slots of the core of such machines by means of known devices apply a shock load, which leads to the displacement of the conductors and the violation of ventilation ducts, as well as deformation and breakage of conductors. In addition, the working surface of the known devices is limited by the width of the slit groove, which can also cause damage to the conductors. The technical result of the proposed solutions is to improve the manufacturability and quality of installation of the windings of the rotors and stators by reducing the complexity of laying wires and secure the wedges in the slots of the core. The technical result is achieved in that the device for mounting the windings of the rotor and stator, comprising a housing and elements of the working surface, the proposed body to perform two pieces of different shapes through an internal cavity of a complex profile in the cavity to position the bolt interacting with its butt-end with the inner surface of the heel, heel run in the form of a hollow sleeve, connected with bolts, in addition, the device is further provided with a frame that interacts with the walls of the groove, and EXT is na square surface - with the outer surface of the housing, the upper part of the body to perform in the form of a tetrahedron, and the lower part of the housing is in the form of cut on both sides of the cone and both parts of the split collar located on opposite sides of the body, the heel is placed in the cavity of the lower housing and connected with the threaded part of the bolt, the end of which has a spherical shape. Figure 1 shows the device for mounting the windings of the rotors and stators in the groove of the core in the working position, side view; figure 2 is a section along a-A; figure 3 is a device for mounting a winding of the rotor and stator in the groove of the core in the initial position, side view; figure 4 is a section along B-B. Fixture for mounting the windings of the rotors and stators includes a housing 1 consisting of the upper part 2 in the form of a tetrahedron and the lower part 3 in the form of cut on both sides of the cone divided by the flange 4. In addition, the housing 1 has an inner cavity 5 of a complex profile. In the cavity 5 is the 6 bolt with a spherical face 7, which interacts with the inner surface 8 of the heel 9, made in the form of a hollow sleeve. The heel 9 is fastened with the bolt 6 by means of the threaded connection. Fixture for mounting the windings of the rotor and stator is further provided with a frame 10, which interacts with its inner surface with the outer surface of the housing 1, and externally the surface 11 - with the sides of the groove 12 of the core. Fixture for mounting the windings of the rotors and stators works as follows. In the initial position, the device is inserted into the groove 12 of the core at any distance from the edge of the groove. Thus the bottom part 3 of the housing 1 is located in the upper part of the groove 12. The shape of the lower part 3 of the housing 1 in the form of cut on both sides of the cone allows the device to freely accommodate and move through the length of the groove 12, as a cone of the housing 1 is oriented along the groove 12 and the frame 10 is in its upper position. When switching device in the working position of the frame 10 together with the housing 1 is rotated 90°. The surface cut from two sides of the cone bottom 3 of the housing 1 is in contact with the inclined surfaces 13 (dovetail) the upper part of the groove 12. Frame 10 is lowered into the groove 12 along the cut sides of the cone bottom 3 of the housing 1 until it stops in the flange 4 and the surfaces 11 secures the device in the slot, keeping it from radial offset. When the crimping slot of the winding of the coil 14 are fixed in the slots 12 through exposure to the heel 9, with the inner surface 8 which communicates spherical end 7 of the bolt 6, moving down along the threaded connection by turning the bolt head 6. The external surface of the bottom part 3 of the building is 1 and is in contact with the surface 13 of the groove 12 with a force, which further secures the fixture. When installing the elastic strips 15 under a wedge (not shown in the figure, the profile of the wedge corresponds to the shape of the upper part of the groove, such as "swallow's tail"), the device translates the original position. After placement of the spacers 15 in the slots 12 without disturbing the geometry of the axial ducts (not shown in the figure) is pressing strips 15 using a similar device works. When talinovce slot of the winding, which occurs simultaneously with the installation of elastic strips, the device is placed in front of the wedge and presses the elastic strip 15 before moving along the groove 12 wedge, reducing the force of his movement, which prevents longitudinal displacement of the elastic strips and, as a consequence, damage to the ducts of the winding. After the installation of the wedge device is shifted to the next section of the groove and talinovka happens in a similar way. Proposed fixture for mounting the windings of the rotors and stators significantly improves the manufacturability of the Assembly due to mechanization fixing coils, styling elastic strips and wedges into the slots of the core, and also improves the quality of the winding by eliminating unwanted displacements and damage the mounted winding elements. p> 1.
