(54) MACHINE FOR WELTING ELECTRIC STATORS ETHRICALLY L1A SHI N

The invention relates to process equipment for manufacturing electrical machines, in particular, to stator winding machines for forming and stacking coil groups in a stator package.

A device for winding the stators of electric machines is known, comprising a stator package latching mechanism associated with a hydraulic actuator and auxiliary templates located at the ends of the package made in the form of slats located between the slots fitted with hooks at the ends hooked onto the main templates united by the common stand. moreover, auxiliary templates are located diametrically and have the possibility of radial displacements fl.

However, the presence of a removable shaping tool requires time for its installation and removal of the end of the winding process.

Also known is a machine for winding the stators of electric machines, containing a circular crown made in the form of a disk with shaping beads attached to it, mechanisms for turning

Howling of the crown and to ensure its movement along the axis of the stator, a device for fixing the wrapped stator G 2.

A disadvantage of this device is that to lay the multi-colored windings it is necessary to install and fasten additional elements (support canopies) and remove them after the end of the stator winding, resulting in a decrease in the production of the machine.

The purpose of the invention is to increase productivity when stacking a lot of russian windings.

For this, the circular crown disk is divided into segments, each of which has an individual alternation drive along the stator axis.

In FIG, 1 pan general tool machine; but FIG 2 is a view A of FIG. one.

The machine contains a st-igin 1, on which is located a rotary d ck 2 with a device 3 for fiksapin on both the FGmigator stator 4, a Pivotal disk 2 coonHiic Fi. rotary discs of which there are circular KOpOEibi, each two segments 8 (fig. 2) with shape hooks 9, Each segment has an individual drive of its movement along the stator axis, containing three screw pairs of central 1O and two lateral 11 with clamped on them gear 12, coeaHHe nymn among themselves gear wheels 13 and 14. Seg ten You have 8 pairs of top and bottom NINs through a central screw pair 1O connected to each other by a toroidal gear coupling 15. 15. Each central screw napav 10 through gear 16 is connected to a gear wheel 17. One of the side screw pairs 11c is connected by gear 18: tooth 19. Gears 17, 22, 22 are mounted on gears 17 and gear sectors 19 to provide a kinematic check of communication with copiers 23, 24, 26 mounted on the cross bar 7. To ensure rotation of the circular corona (segments with shape-forming kdoch mi 9) serves Maltese mechanics 26 m The machine operates as follows. The stator 4 (Fig. 1) is installed in the rot to the rotary disk 2 and fixed with the device 3. Lower the yoke 7, connect the upper and lower segments 8 pairwise with torn-tooth gear clutches 15. Then use the Maltese mechanism 26 to turn the disk 2 on the DZ for the equipment © “And all working bodies to the initial position and the supply of the -command to the automatic stator winding by the wire-laying machine of the storoobrazmotochny machine (“ and the drawing is not yet approved). The removal of the workers to the initial position takes place in the eating sequence. When iSerotot disk 2 and the associated disk in that arrow (Fig. 2) roller 2O comes in contact with the copier 23 and rotates the toothed sector 19. Through the shakester 18, - 12 gears 13, 14 transmit sync (M1Noe movement all screw bolts Yu, 11, moving the lower and upper segments 8 and respectively forming hook 9 in the axial direction to the stator 4 (screw. pairs of upper and lower segments have different thread directions; gears 13 and 14 when moving the working bodies into the working position connected with a special message, on not shown.) After this, production of 1t of the coil groups of the first tusk is made, then turn the disk 2 and the workers connected to it at a given angle, whose velccin depends on the stator winding circuit, for example, for a pole-shaped stator at an angle 120. Ropik 21 it comes into contact with the cam 24 and through the gear wheel 17, the bristle 16, the central screw pair 10, the gear wheel 14 and the screw pairs 11 connected to it, displaces the lower and upper segments 8 in the axial direction from the stator. In so doing, the shaping hooks deflect to form a space for laying a part of the coil groups of the second tier. At the end of the winding disk 2 psjo. It is rotated at 120 °, the roller 22 comes into contact with the cam 25 and, similarly to the previous one, moves the second pair of segment 8 for laying the remaining coil groups of the second tier. At the end of the winding cycle, the yoke 7 is moved to the upper position, the shaping hook 9 is removed from the coil groups laid into the stator, and the stator 4 is removed from the machine. The presence of the segments allows simultaneously with the winding to lay the coils of the first and second Rus (i.e., the coil of the first Rus on undiluted, and part of the coils of the second Rus on divorced shape-generating hook in accordance with the winding scheme). The individual drive allows the movement at any time (in accordance with the tTBHH with the specified program of the machine work) time. The invention The machine for winding the stator of electric machines, containing a circular crown, made in the form of a disk with fastening hooks attached to it, 1 mechaaism dp, turn circular, crowns and to ensure its movement along the stator axis, a device for fixing the stator wound, characterized by that, with HGJitxi, increasing bale producers. With a multi-layered winding, the circular corsing disk is divided into segments, each of which is connected with the drive of its displacement along the axis of the stator.
