The invention relates to process equipment for manufacturing electric coils and can be used in the electrical industry.

The purpose of the invention is to improve the quality of the products by eliminating the twisting of the wire.

The drawing shows the kinematic scheme of the proposed machine.

The winding machine has a return coil spindle, connected via gear 2 with continuously variable transmission 3 5 having a driven roller 4 and a driving disk 5, and through a flexible shaft 6 and gear 7 connected to a winding head 8 containing a hollow spindle 9 and a leash 10 for winding and laying out the wire. The machine has a guide sleeve 11, a tensioning device 2, a turntable 13 with mandrels 14 for nama / high-speed coils, and also a screw pair 15 with a motor and a contact 16, and a sensor for the diameter of the sending coil.

The sensor has a tracking element 17 attached to the piston 18 of the spring-loaded pneumatic cylinder 19, the casing of which is mounted in the guides 20

with the possibility of axial movement

and carries a contact 21, the piston having a conical part 22, with which the spring-loaded slider 23 contacts the contacts 24 to turn on the screw pair. For each type of cat-ears that are wound up or delivered, a corresponding stepless transfer of Zo is selected. The control circuit in the drawing is not shown.

The spindle fastens the cat-eye outlet 25 5 with which the wire 26 presses onto the cat-eye carcass 27. The wire 26 is charged through the guide sleeve 1, the tensioner 12 and the hollow spindle 9, and its end is fixed - they are put on the frame of the namgamoi cat-ears 27.

During the operation of the machine, the wire 26 is removed from the outgoing cat ears 25, passes through the guide sleeve 11, the tension device 12, through the polishing spindle 9 and with the help of the lead 0 is wound on a fixed frame, the coil 27. At the same time, the rotational movement from the spindle 9 through gear 7, flexible shaft 6, continuously variable gear 3 and gear 2 is transferred to the spindle 1 of the returning roller. Blah

gears connected to a lead with a mandrel (in this case gears 2 and 7);

Nc is the average diameter of the pre-formed coil 27;

D (, C - dig1 meter of the sending coil 25.

To set the initial position, the following operations are carried out: in the continuously variable transmission 3, the calculated gear ratio K is set; air is fed to the right (according to the drawing) cavity of the pneumatic cylinder 19 so that the piston with the next element 17 is engaged in the extreme left position; pin 16 is installed in close proximity to pin 21; disconnect the screw pair 15; air is fed to the left. the cavity of the pneumatic cylinder, which leads to the removal of the follower element 17 from the surface of the outgoing valve 25, then winding can be performed.

When the winding of the coil 27 is completed, the table 13 is rotated to wind the next coil. However, since the sending coil has already worked off by a certain amount, it is necessary to change accordingly K. This is done in the following way. Air flows into the right cavity of the pneumatic cylinder and its piston occupies the left position. In this case, the slider 23 interacts with the tapered part 22 and closes the contacts 2A, which leads to turning on the screw pair 15 and moving the roller 4 to the stepless transmission 3. In this case, the sensor moves along the guides 20 to the left by the amount of cat-eye contact, contacts 16 and 2 consumption, adjustment stops niaeTCH.
