The invention relates to electrical engineering, in particular, equipment for the manufacture of electrical machines, and can be used in electrical, electronic, electronic and other industries in the manufacture of stator windings for asynchronous, stepping motors and micromachines for general industrial use.

The purpose of the invention is to simplify the design of the machine.

FIG. 1 shows the proposed machine, a general view; in fig. 2 is a view along arrow of FIG. one.

The machine contains a bed 1, mounted on the bed 1, a mechanism 2 for fastening and turning the stator from the drive 3, a tensioning mechanism 4 with a balloon 5, a conductor 6 with a mechanism 7 for reciprocating and swinging movement from the drive 8, wire-laying devices 9 with guide capillaries 10 for a wire; a mechanism for radial movement of wire-laying devices 9, made in the form of two concentrically mounted bushings II and 12. The internal sleeve 11 is made with slots 13 forming elastic consoles 14 on which wires are fixed doukladchiki 9. The outer sleeve 12 is formed with an opening 15, covering provodoukladchiki 9. The hole 15 is eccentrically positioned relative to the hub axle 12.

stator winding. The outer sleeve 12 is kinematically connected with a rotational drive, made in the form of a cam 16 mounted on the conductor 6, and a ratchet wheel 17 mounted on the sleeve 12, with a pawl 18 mounted on the axis 19 of the drive housing 8.

A wire 21 is placed on the reels 20. A wire clip 22 is mounted on the housing of the mechanism 2 for fastening and rotating the stator 23, the windings of the coil 24 being wound on the teeth of which.

The machine works as follows.

The reels 20 (Fig. 1) with the winding wire 21 are installed in the tension-tensioning mechanism 4 and covered with a balloon 5 so that at high coiling speeds the wire 21 is not thrown away from the reel, twisted or looped. The wire 21 is passed through the tension-tensioning mechanism, the conductor 6, the sleeve 11 of the mechanism for the radial movement of the wire-laying 9, the guide capillaries 10 and is fixed in the clips 22 on the housing of the mechanism 2 for fastening and turning the stator. The stator 23 is installed and fixed in the mechanism 2 for fastening and turning the stator. Turn on the machine and start winding the winding. In this case, the guides

The capillaries 10 inside the stator 23 describe a closed path that approximates the shape of the coil. The two straight sections of the trajectory pass strictly along the slots in which (due to the reciprocating movement of the conductor 6 from the actuator 8) the winding is wound. Two closing sections of the trajectory pass outside the stator core 23 and are provided with an initial movement (turning at a predetermined angle) of the conductor 6 with the conductor 9 and guiding capillaries 10 from the drive 8. Driving the specified number of movements along this trajectory, the guide capillaries wind the windings coils 24 with an appropriate number of turns; in this case, wire-laying machines 9 with capillaries 10 move in a radial direction discretely for each turn (Fig. 2).

The movement of the conductor 9 with guide capillaries 10 (Fig. 1) in the radial direction is provided by the mechanism of the radial movement of the conductor laying as follows: when the conductor 6 rotates in one direction from the cam 16 rigidly fixed on the conductor 6, the dog 18 is inserted into the engagement with the ratchet wheel 17. Since the pawl 18 is fixed on the gear housing 7 through the axle 19, and the ratchet wheel 17 is fixed on the sleeve 12, the sleeve 12 stops and then rotates further l 6 with sleeve 11 and wirelayers 9 relative to it. In this case, the pavers 9 interact with the surface of the eccentric hole 15 of the sleeve 12, which leads to their movement in the radial direction due to the deflection of the elastic arms 14 of the sleeve 11 (Fig. 2). When the conductor 6 is rotated in the opposite direction, the sleeves 11 and 12 with the wire-laying 9 rotate as one piece. Thus, with the swinging movement of the conductor 6, with each turn, there is a relative shift in the angle of the sleeves 12 and 11 with the wirelayers 9 and a discrete radial shift of the wirelayers 9 when the latter interacts with the eccentric hole 15 of the sleeve 12. Discrete movement of the wirelayers 9 with guide capillaries 10 occurs when each turn is formed, and its value depends on the relative angular displacement of the sleeves 11 and 12, which is determined by the pin of the teeth of the ratchet wheel 17 and the moment bearing sleeve 12 with a ratchet wheel 17 defined by the relative position of the cam profile 16. Full radial movement of the guide capillaries 10, equal to the height h of the winding winding of the stator roller 24 of the stator 23, occurs when

the relative angular displacement of the sleeves 11 and 12 is 180 ° and is provided with an eccentricity e of the hole 15 equal to half the height of the coil 24.

If not all the stator windings are wound at the same time, but only parts of them, then after winding is completed, the transition to the next stator poles is ensured by turning the latter by a predetermined angle from the drive 3. Upon completion

In the case of stator winding, the machine is turned off and preparatory operations are performed for winding the next stator, etc.

Thus, the proposed machine (unlike the known ones) provides a series of 5 stacks of wires in each layer of the winding coil, and its design is much simpler (compared to the prototype), since it does not require reversing the movement of the radially moving bushings relative to each other 20 and eliminates the need to use two opposite-acting ratchet mechanisms controlled by a position sensor and an electromagnet.
