Description

The proposed invention relates to machines for winding the stators and rotors of electrical machines and has the goal of precisely and accurately implementing it. ,

The essence of the invention is reduced to the use of a trmu, that for the production of one turn of the wire in the stator or rotor winding and the return feed of it to the winder, a tapered drum is used. intermittently retracted and equipped with devices for stretching the wire for a certain distance, winding eio on the drum, removing it from the drum, and feeding back to the coiler.

In FIG. 1 depicts a general view of the machine; FIG. 2 and 3 are side and top views of the ring for capturing; FIG. 4- wire clamp; FIG. 5-spring roller; FIG. b-hook; it J- cone with spring.

The rotating table 7, on which the wrapped part is placed, is mounted on the bed 2. The upper part of the latter is made in the form of a narrow table with a guide groove 3, in which the clamp 4c is attached with the weight 5 attached to it. Right, the end of the said table is lower than the height of the clamp 4, in parallel with the table, on the bracket 5 there is placed a taper 7 rotating from a motor drive, connected to the shaft 8 by a ribbon spring 9, one end of which is fixed on the inside of the upper (434), ,,:,;

of the cone 7 and the second on the shaft 8. On the latter there is a spring 70 still tightly wound, one end of which is free and the other attached to the bracket 5. The cone 7 is enclosed by a ring 7 / for removing the wire. The ring 7 / is integral with the lever 72 connected to the handle 75 by a system of levers J4 and 75. A groove is cut in the upper surface of the ring, in which a clamp 75 runs that can engage with the spring-loaded roller 77. The latter can move inside the cone {wearing the ring on him 77.

Details of the clamping device 76 are shown in FIG. 3 and 4. A 7P hairpin is attached to the spring claws 75, facilitating the release of the wire when pressed.

In the lower surface of the cone 7, a KaHaulna is cut, in which the coupling hook 20 (Fig. 6) is moving, connected by a cable with a clip 4. The length of the cable is equal to the circumference of the cone 7.

Winding is performed as follows. The winder pulls the wire B into the slot of the wrapped machine and its end is fastened in the clamp 4. When the motor is turned on, after the factory until the spring 9 fails, the cone 7 begins to rotate, dragging to collect the hook, which, thanks to the cable, doesn’t

the clamp with the wire along the groove 3. After the taper 7 makes one turn, the clamp 4 will reach the edge of the bed and the wire will fall into the expanding hole of the clamp J6. Further the following happens. The hook 20, abutted against the stop 27, is released from engagement with the cone and the load 5 returns the clip 4 back; at the same time, the clamp / b comes into engagement with the roller / 7 and, being fascinated by the latter, doesn’t have a wire that is wound on the cone 7. When it is released by the clip 4, the wire rises a little up, due to the tilt of the table, and contributes to the correctness of winding on the cone 7, since otherwise, with full rotation of the latter, the clamp / 5 would be above the wire.

When a sufficient wire valley is wound around the cone, the winder turns off the motor and the handle 75 is not there, simultaneously turning the disk 7 by hand. The lever 75 raises the ring 77, which becomes in the position indicated in FIG. 1, the dotted line. At the same time, thanks to the gearing of the rail 22, associated with the handle 7J, with the gear 25, the lever 24 rotates.

the wire removed from the dog house by the ring 77. When the lever 75 is rotated, the ring 77 and the lever 24 are put back in place. The end of the wire is released by the clamp J6 due to the stop of the 7P stud in the support rings of the bracket, while lifting the ring 77. The spring 9, unscrewing, returns the cone .7 to its original position. After this machine is ready for the next operation.

The subject matter of the invention.

A machine for winding rotors and stators of electric machines, differing in the use of cone 7, periodically causing damage and serving for winding a conductor supplied from the winding machine by means of a clamp 4, connected by a cable and a hook 20 with a cone 7 for the turnaround time , to clip 16, connected using spring-mounted roller 77 with a cone 7 at the same time, moreover, to remove the conductor from the cone and transfer it back to the winder; leverage system 72, 24./ Figb f.
