In addition, the mobility of the sponges contributes to the cleaning of the mechanism of destruction of the insulation on the leads from the isolation waste, and the multichromic notch 14 on the guide surface of the sponge 13 and the same notch 9 on the sponge 8 when the sponges are closed to a size equal to the height of the stop 21, provides effective and efficient destruction of the insulation at the terminals. The mobility of the jaws, in combination with interchangeable stops, expands the range of winding wires used depending on the diameter.

rod 23, driven in motion through the shaft 24, the gear wheel 25, the rail 26 with a groove 27 and in contact with different levels of 28 and element 29, and the actuator 30,

The mobility of the sponge 8 together with the rod 18 and their placement on the same coaxial bark spindle together with the L-shaped lever 22 allow the formed output to be held and, while the core rotates around its axis during winding, it does not allow the tension in the wire to level it.

In addition, the mobility of the jaws helps to clean the insulation breakdown mechanism at the terminals of the insulation waste, and the multi-edge notch 14 on the guide surface of the jaw 13 and the same notch 9 on the jaw 8 when the jaws are closed to a size equal to the height of the stop 21 , vigorous destruction of the insulation on the findings. The mobility of the jaws, in combination with interchangeable stops, expands the range of winding wires used, depending on the diameter.

The presence of a terminal spreader on the sponge J 3, adjacent to its guide surface, allows it to always be opposite the spigot slot for the output 31 (FIG. 8), when the sponges are closed, the spindle 11 is movable and moves through the center 12.

A pike branch 32 (FIG. 7) is in the plane of the slit-lash and, therefore, to perform a continuous and waste-free connection of the lamella pin 33 (Fig. 5),

The continuous execution of the output increases the reliability of the winding, since in this case it is enough contact with the lamella of the end of the previous section so that the subsequent section has contact with the lamella.

The spring 20 of the rod 18 allows it to sink into the sponge 8 when the sponges are closed and to move out of it when

opening sponges. The presence in the machine of the mechanism for forming the leads ensures a satisfactory formation of the frontal part of the winding and with a diameter of the winding wire more than 1 mm. The G-shaped form of the lever 22 allows it to be mounted on the flange 10 of the spindle 1 1 together with the sponge 8.

The spring 23 (FIG. 1) of the lever 22 allows to take into account the increase in the frontal part of the winding, since the lever 22 sits on the shaft 24 movably and is connected to it through the specified spring. Groove 27

on rail 26, 28-ki 26 different levels, 26 by groove 27 along the upper bore 28, and element 29, located in the longitudinal section 34. After winding the first sectional section of the container 34 between the windings, the conductor 5 stops at the position shown in FIG. 3. With the aid of the actuator 30, through its element 29, the rail 26, the gear wheel 25 and the shaft 24, the lever 22 is moved to a horizontal position (Fig. 11).

Then, when the core is stationary, the spindle 11 rotates to the position shown in FIG. 12, the conductor 5 moves to the position shown in FIG. P. The spindle 11 rotates to the position M - Mj, while the groove 27 of the rail 26 slides along the lower side of the cups 28 of the cup 34, thereby keeping it in a horizontal position. Thereafter, the magnet wire 37 is located between the collector and the rod 18 (Fig. 11). When the conductor moves to the right and upward, the wire 37, hooking on the rod 18, is formed around it in the form of a pin (Fig. 10). With the aid of the actuator 30, the lever 22 presses the outward withdrawal branch 36 (Fig. 7). Then winding the second section is performed. On the penultimate turn, the conductor 5 stops at the position shown in FIG. 3, and the measles is rotated so that the slot of the collector, to, the output must be connected, is located on the line 0 - 0 (Figure 2). Together with the collector, the spindle 11 with the sponge 8 and the stem 18c of the terminal located on it is rotated to the same position.

The irregularity of the lamellae and slots on the collector is taken into account by a microprocessor-based device for numerical control and is compensated by the necessary rotation of the core.

in order to secure the position of the lever 22 in fixed positions during the rotation of the spindle 11 around its axis.

The light sensor 35 is used to read the data on the number of lamellae on the collector, their angular location, and to store this data in the memory of the microprocessor rack of the numerical program control, for example the rack of model 2 C -85. Pin 33 has both the incoming branch 32 and the leaving branch 36 formed by the actuator 37.

The machine works as follows.

The anchor 3 is mounted on the center 12 with the collector end of the shaft, moving it up the measles is inserted into the opposite end of the shaft between the jaws of the cartridge 2 and fixed in it so that one of the package core slots is opposite the conductor 5. The light sensor 35 manually approaches the collector. After turning on the machine for automatic operation, the measles makes one revolution and stops. The light sensor 35 is manually retracted to its previous position, and the winding wire is passed through a tensioning device (not shown), the conductor 5 and the first slot of the collector 4 and is fixed to the collector end of the shaft. In the initial position, the conductor 5 is opposite the groove of the core, the sponge 13 is in the position retracted from the centerline (Fig. 12), the lever 22 is in the horizontal position (Fig. P), and c) the lancer 10 of the spindle 11 is rotated so that its line H, -H coincides with the line M, - M (Fig. 12). When you press the button again, the Start program (not shown) drive 30 through the element 29 and the groove 27 ne35

The rail 26 moves upward, turning the wheel 25, and with it the shaft 24 and the G-shaped lever 22, which fixes pin 31 (Fig. 5). Next, the conductor 5, moving along and across the axis of the core during the co-ordinated rotation of the core, according to the program, places the wire into the slots of the package core. At the same time, the spindle 11, and with it the lever 22, perform synchronous movements in the program with the bark 3, keeping the output branch 36 pressed against the shaft core, due to the movement of the reel

The sponge 13 moves with the aid of a piston 15 in the direction of the sponge 8 up to the stop 21 (Fig. 2 and 6), forming a groove whose width is smaller than the wire diameter by the amount of double insulation thickness opposite the required collector slot. When the jaws 8 and 13 are closed, the rod 18 is sunk into the sponge 8 so that pin 31 (Fig. 8) is on the conical part 19 of the rod.

Under the action of the rammer on pin 31, through it on the conical part of the rod, the latter is sunk into the sponge 8 and does not prevent the output from tangling along the groove formed by the jaws. The terminal, the passage between the jaws along their notched surfaces, is cleared of insulation and pushes along the slot of the collector, forming an uncut and waste-free outlet 33 (Fig. 5). This output is the end of the first section and the beginning of the second section. The subsequent sections of the winding are performed as described. After performing the entire winding, the machine stops. The wire is cut off manually, and the measles is removed from the machine also manually.
