utl h The invention relates to electrical engineering and can be used in the manufacture of electrical coils with side taps. A winding machine is known in which the winding mandrel is a plug with two rods, one of which is wound on a turn of a coil and on the other is a side tap of a Cl. The machine is inefficient, because during the transfer of the winding head from winding the coil to forming a branch, the winding process is interrupted, and the winding of the coil is performed in a pile, because there is no sequential layout device. In addition, the machine does not allow winding in two layers with taps from each layer. A device for winding electric coils is known, comprising a spindle with a mandrel, a yarn feeder associated with a rotational drive and a reciprocating movement, a faceplate with pins, the spindle being provided with a drive for its transverse movement, and the yarn feeder made in the form of two tubes mounted between the pins of the faceplate 2 However, the known device has a complex structure with several drives. The purpose of the invention is to simplify the design. This goal is achieved in that the device for winding electrical coils with taps, contains a spindle with a faceplate having a groove pickup mechanism with a reverse and a mandrel for lateral taps, the working end of the mandrel is made from the cam profile, and the other is with a screw channel, with the mandrel installed in the slot of the face plate with the possibility of rotation and reciprocating movement along the axis of the plan of the washer. FIG. 1 shows a device in the initial position for forming a first outlet, a general view; in fig. 2 - the same; in fig. 3 is a diagram of the tension of the wire during the formation of a tap; in fig. 4 - the same, with the return-pic. tunneling movement of the mandrel, in FIG. 5 is a diagram of the possible automation of the device; in fig. b - scheme of formation of the first lateral outlet in the initial stage; in fig. 7 - cf formation of the first lateral outlet in the final stage; in fig. 8 - mouth roystvo, view before winding up the first layer; in fig. 9 - the beginning of the development of the first side branch of the second layer; in fig. 10 - the end of the formation of the first side branch of the second layer; in fig. 11 - arranged in the reverse of the pickup mechanism; in fig. 12-14 - phases of formation of a tap. The device comprises a spindle 1 with a faceplate 2, in which there is a groove 3, a cylindrical mandrel 4, the working end of which is made with a cam profile 5, and the other with a helical groove b. The cam 5 of the mandrel 4 has a length equal to the length of the frame of the winding coils. The core 4 is located in the bushing 7, in which there is a locking ball 8 and a guide pin: 9. The collet 10 is fixed in the spindle 1, and the rear center 11 with the faceplate 12 is coaxial with it. The layout of the wire is carried out by the layout mechanism 13 with the reverse. The wire 14 is located on the reel 15, and the coil frame 16 is in the collet 10. In an automated version, the device contains annular magnets 17 (Fig. 5) and a ring 18 installed with the possibility of reciprocating movement along the spindle; n 19, hard-coded, replica in faceplate, 2; two rows of linear switches 20 limit switches 21; cylindrical cams 22 with kiawkami 23; mechanism 13 layout / equipped with fingers 24, (Fig. 11) and electromagnets 25. The device operates as follows. The frame 16 is clamped in the collet 10, the wire 14 is secured to the frame 16, and the device is put into operation. After winding a certain number of turns, the mandrel 4 is fed into the winding zone and is stopped by the ball 8. The wire 14 attaches to the cam 5 and forms a loop (lateral retraction). After the formation of the retraction, winding of the second coil begins. The mandrel 4 with the sleeve 7 rotates together with the faceplate 2. After winding the second coil, the mandrel 4 moves forward again, and the guide pin 9, being in the helical groove 6, with the beginning of advancement of the Guideline 4, at the same time turns it around its own axis, Thus, the tension of the lead is weakened (Fig. 4). . . . .. l. A gap is formed between the cam 5 and the wire 14, which contributes to the further free movement of the mandrel 4 into the winding zone of the next branch. When the mandrel 4 approaches the place where the second branch is formed, the guide pin 9 rotates the mandrel 4 through a certain angle. And the cam 5 returns to the position necessary to form the second branch. When the winding is completed, the mandrel returns to its original position. The return of the mandrel 4 to its original position can be performed with the rotation-t. Research Institute of faceplate, as well as when the drive is off. In the automated version, the mandrel 4 (Fig. 5) is rigidly fixed in the ring 18, and under the action of the ring magnets 17, the signals of the linear switches 20 are discretely fed to the initial position. The ring 18 moves along the spindle 1 and the guides 19 rigidly fixed in the spindle faceplate. The pickup mechanism 13 with the fingers 24 (FIG. 11), when it moves through the cylindrical cams 22 (FIG. 5), acts on the linear switches 20 and the end switches 21. The grooves 23 on the cylindrical cams represent a helix with different elevation angles at different plots. The cylindrical cams are driven through a gear (depending on the wire diameter and the packing density). In the places where the lateral branches of the grooves are formed, the grooves 23 have sections of a helical line with lifting angles different from the lifting angles at the winding points of the roller so that the water will provide some spacing between the coils / prevent the raid of the second turn on the mandrel, and Also, in order to coordinate the formation of taps on the second layer, it is also possible to manufacture winding sections with different "1 steps." The automated version also has a guide pin 9, a cam 5 and a groove b (not shown in Fig. 5). The electromagnets (Fig. 11) are switched for reversing according to the signal of the limit switch 21, and one of the fingers 24 is disengaged from the other cam. The second layer is wound by means of taps using a second mandrel installed on the faceplate 12, and as the second Help comes out of the faceplate 12. The first mandrel 4 is removed to the faceplate by the commands of switches 20 and 21, freeing lateral taps of the first layer. Thus, the proposed device allows winding a series of coils on one frame with side taps between the coils in case of a series Winding in one cycle of the engine operation without disconnecting and re-switching on when a new branch is formed. The discrete movement of the mandrel 4. in the sleeve 7 can be carried out from a lush electromagnetic, pneumatic actuators, as well as manually. . The positive effect of using the proposed device is to significantly simplify the CONSTRUCTION by eliminating complex driving devices.
