The invention relates to technological equipment for winding coil distributed windings of electrical machines and can be used in the electrical engineering industry.

The aim of the invention is to simplify the design of the device and increase the reliability of operation when winding the stators with a distributed winding of various sizes.

Fig, 1 shows the device, a general view; in fig. 2-5 are partial cross-sections of the gripping member in various working positions.

The device comprises a reel 1 with a planet carrier 2 and a wire 3 tucked into it, mounted on the drive shaft 4 cups. A plate 5 with hinged pullers 6 is also mounted on the drive shaft 4. A rod 8 is fixed to the rod 7 placed inside the shaft 4 with the possibility of axial movement. One piece of the template 9 is fitted along its longitudinal axis groove

The carriage 15 is placed in the groove 10 of the template 9 with the ability to move along the axis 11 and interacts with the pin 16 of the mandrel 17. On the carriage 15 the hinge is fixed to the gripping element 18, made in the form of a two shoulders rytag, and also the clamping spring 19 is rigidly fixed.

It comes with a release spring plate 20, which is rigidly fixed to the lower part of the template 9, and its mass exceeds the weight of the hook-shaped shoulder in order to hold it in the upper position.

The device works as follows

The drive (not shown) moves the bar 8 down (Fig. 1), while the small stage of the template 9 enters the pin mandrel 17, and the reel 1 together with the carrier winds the winding wire 3 on the small stage of the template 9. At the same time, the pullers 6, - when reciprocating, throw the turns of the windings into the gaps between the pins 16 of the mandrel 17. After winding a certain number of coils, the template 9 is lowered (FIG. 2), while the pins 16 touch the carriage 15 and move it relative to the template 9 upwards. Simultaneously, under the action of the release spring 20, the gripping element 18 is released from the clamping spring 19, and its hook-shaped shoulder rises, after which the second stage of the template 9 is wound. After the required number of turns is wound, the template 9 is lowered and the transition coil is wound on a large step. winding (Fig. 3). The template 9 continues to move downward (Fig. 4) while the support 14 acts on the gripping element 18, after which the clamping spring 19 clamps one shoulder of the gripping element 18, and its other hook-shaped shoulder grips the transition coil, after which, by the action of the pullers 6, all remaining , on steps 9, turns in the gap between the pins

16 of the pin holder 17. Then, the template 9 rises (FIG. 5), the carriage 15 under the action of the return spring 12 moves downward with respect to the template 9, while the hook-shaped shoulder of the gripping element 18 continues to hold the transition coil, and the pin holder 17 is rotated 180 and the template 9 is lowered to the low-level winding zone. After winding several turns (3-4 turns), the template 9 continues to descend, but so that the small step is in the winding zone, while under the action of the pins 16, the carriage 15 rises upwards relative to the template 9, and the gripping element 18 unscrews the transition coil and the cycle repeats. The invention The device for winding coil groups of distributed windings with pattern / 7 f6 Fig, 1 interpolar connections, containing a multi-stage sliding template with a stop, made of two parts, a rotary drive reel, a pin mandrel for transferring or pulling the coils into the magnetic core package, with pins arranged around the circumference, a gripping element for fixing the wire in the interpolar connections and a puller, characterized in that ensuring the reliability of work the template is made with a groove and is provided with an axis rigidly fixed therein with a groove and a spring-loaded carriage mounted on an axis with the possibility of movement, at the same time capturing the element is hinged on the carriage, and the stop is made under-spring and is located in the slot of the axis.
