SU73796A1 - Coil winding machine for toroidal cores - Google Patents

Description

The proposed machine, which serves for winding coils on toroidal cores, is made according to the type of machines with a detachable winding coil into which the core is inserted, and with a device for changing the winding pitch.

The dryness of the invention lies in the fact that the said device is made in the form of two folded discs, turning one relative to the other and containing a system of teeth located in the radial grooves of one disc II, entering with their projections into the curved groove of another disc. At these turns of the discs, a different number of teeth is pulled out, which changes the gear ratio of the transmission between the core holder and the drive.

The invention is explained in FIG. 1-5.

FIG. 1 shows a rotary disk with a shaped groove g; in fig. 2-second rotary disk with teeth N, placed in the radial grooves M, in FIG. 3-kinematic diagram of the machine; in fig. 4 shows a device for mounting a transformer core but arrow A; in fig. 5 is a view of the stacking device along arrow B.

The feed pitch is changed using the figure Z curve on the disk (Fig. 1) as it rotates in one direction or another, so that the teeth L can move inwards from the periphery of the second disk (Fig. 2) and, conversely, from the inside to the top. The teeth are placed in the grooves M, with their projections 10 they fit into the curve Z groove of the first disc, leaving a certain number of teeth necessary for turning the wheel 2 (Fig. 3) at a certain angle. This, in turn, will turn the device 8 also to the corresponding angle.

The motor 12 rotates consecutively worm gears 3 ii 4.

Gear 3 is placed on the same axis with a device for changing the schtag /, consisting of two rotary disks with a set of teeth (Fig. 1 and 2); a gear wheel 5 is mounted on the same axis, driving device 6 and p. 7. laying the wire on the transformer core.

The device for changing the pitch periodically interlocks with the wheel 2, which drives the screw pair 11, on the axis of which there is an apparatus 8 for

installation core transformer.

The device laying the wire (Figs. 3, 4 and 5) consists of gear 6 and coil 7, which is free to sit on the axis. The product is placed on the table of the device 8 so that the stacking device passes through its center.

This is done by detachable sectors of gear 6 and coil 7. After winding the wire on coil 7, it is threaded into a spigot-shaped opening in the removable sector of gear 6, then it is put on roller 9.

The handle 14 serves to actuate the machine by hand. To move the product to the desired position, use the knob 13.

Counter 15 shows how many turns laid on the core of the transformer.
