    Apparatus for winding stators or the like includes a winding form and a winding nozzle, rotatable about the form, for winding a wire on the form. A collecting tool or transfer tool is provided for receiving windings from the form, a stripper is provided to strip windings from the form onto the collecting tool and a clamping means is provided for clamping a wire between individual winding operations. The apparatus includes means for simultaneously moving the winding nozzle, stripping means and clamping means during the stripping of the windings from the form onto the collecting tool. Thus, the wire from the last-wound windings will be prevented from being drawn to a finer diameter when stripped from the form or it will not be necessary to pull additional wire out of the winding nozzle in which event, on starting the next winding process, there would be a strong jerk which could result in breakage.

    专利说明:

    The invention relates to the manufacture of electric machines, and specifically to special devices for winding coils, which are then put on the stators of electrically machines during the subsequent working operation. Up to now, on such winding devices, the coils were usually wound onto the template by means of a rotating leash for winding. After winding one coil or a group of concentric rolls of coils, the coiled wire between the winding lead and the template was gripped by the clamping and forming mechanism, and then the template grips the shaft of the receiving mandrel so that after that the coil on the template is shifted from the template down to the receiving mandrel . During the process of removing the wiring for winding and the clamping mechanism to maintain its position C1 J. The disadvantage of such devices is that the templates must be relatively long so that they can take all the coil headers and hold them up to removal, and The stripper must be appropriate in length and during removal between the coil and the winding lead a long wire is formed. In this case, part of the wire from the winding of the coil freely hanging on the receiving mandrel is pulled back so that the diameter of these turns of the coil decreases. Subsequent donning of the coils onto the stator may damage the wire. In addition, the next movement of the lead for winding leads to a jerk of the wire. The closest in technical essence to the present invention is a device in which the lead for winding is also on the drive shaft and in which a sliding template with a drive for its axial movement is provided, a puller located behind the lead clamping mechanism and receiving mandrel. The winding wire rotates in a defined plane and remains stationary during; removing the wire turns from the template into this winding plane. The clamping mechanism picks up the wire and holds it close to the winding plane. It also remains stationary relative to the axis, while the pullers move axially to remove the last wire turns from the template to the receiving mandrel. The disadvantage of this device is that the pullers during the removal process extend the end of the wire held by the clamping mechanism, as a result of which the wire is pulled back from the last wound coils and a jerk may occur during the subsequent winding process. The purpose of the invention is to eliminate damage to the wire in the winding device. The goal is achieved by the fact that in devices for winding coils of stators of electric machines, containing a lead for winding a wire mounted on a drive shaft, a multistage sliding template with a drive of its axial movement, strippers, a clamping mechanism located behind the drive and a receiving arbor, drive shaft the driver is provided with a drive for its axial movement, and the clamping mechanism and pullers are fixed axially on the driver's drive shaft. In FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 - device pattern, section; in fig. 4 — node I in FIG. 3 in a 90 section plane rotated; FIG. 5 is a view B of FIG. 3. The winding device, as part of an automatic winding and tensioning unit, in which the coils are pre-wound for the stators of electric machines and drawn into the active steel stator pouches, contains a turntable 1 carrying three tension working bodies 2 having the possibility of cyclic movement in three switch positions. In the second switching position, coils and respectively ka are created. carcass 3. The winding tool is a composite pattern 4 / made multistage and sliding with pullers 5. Around the template of the y-lead is the lead b and a mechanism 7 for clamping and cutting the winding wire fixed on the frame 8. The mechanism 7 can be placed without rotation on the support leash 6, but axially movable along with the leash b. Only one clamping device can be used, which, by moving the wire down, cuts it off. Next to the device are the backup coils 9 and 10 with a wire. The device is equipped with a welding mechanism 11. On the base 8 there is a carriage 12, which is connected to the drive 13 with the lead screw 14. On the carriage 12 there is a template 4 and a drive 15, which through the chassis screw 16, nut 17, two shoulders lever 18 mounted on carriage 12, and connecting rod 6 coaxial to the drive shaft of the leash 6, interacting with the template. As an axial drive for the driver 6, as well as a rotationally but axially fixed clamping and removable device 7, as well as pullers 5 axially supported on the design of the driver 6, serves a rotary disk cam 20 located in the lower part of the machine the lever 21 with the roller 22 adjacent to the disk cam 20, through the hinge 23 connected to the lever 21 to the rod 23 and hingedly connected to it 21, placed on the carriage 12 two shoulders lever 24, acts by means fixed on the carriage 12 control columns 25 on the vertically-facing plate 26 connected through the connecting rod 27 with the lead b, pullers -5 and the clamping and cutting device 7, the tubular connecting rod 27 is exactly the same as the connecting rod 1 is aligned with the drive shaft of the leader b connected with an electric motor 28 through a belt pulley 29, a belt 30 and another belt pulley 31 Instead of a drive 15 with a lead screw 14 and instead of a disk drive to the lacha 20, other corresponding drive bodies, in particular an axial drive for a lead b, pullers 5 and clamped The first and the cutting device as well as the axial drive for the template can be placed on the carriage 12. The drive 13 of the carriage 12 is used to change the width of the template 4. Template 4 consists of two relative to each other parts 32 and 33. Both parts of the template . with transverse direction on two guides 34 and 35, which are rigidly connected to the connecting rod 19. In addition, on each part 32 and 33 of the template are rigidly placed, respectively, one rack 36 and 37, - which are diametrically oppositely engaged with a freely rotatably arranged on the connecting rod 19 the toothed wheel 38. In order to hold the two parts 32 and 33 of the template in a certain position with a certain width of the pattern on the portion 32 of the rod 39 fixedly placed on the template part 33 side will provide before the clamping device. For the clamping of the rod 39 there are two washers 40 and 41 inserted into the template portion 33, which are held by means of compression springs 42 and 43; In an inclined position relative to the rod 39 pulled out through the holes in the washers 40 and 41, the rod 39 is clamped in the holes washers 40 and 41. To release this clamp, it is only necessary to insert a bolt 44, pointed at the free end, from the bottom into the hole 45 in the pattern portion 33, and the placement is chosen so that the bolt 44 passes between the washers 40 and 41 and aligns them with the rod 39, so what is a pinch eliminated. The bolt 44 is placed on the movable holder 46 to remove it at the time of winding in the working area. Tension working bodies consist normally; but of annularly placed tightening plates 47 and radially outside them, also radially arranged, cover tape plates 48. The device operates as follows. Tension working bodies 2 by periodic feeding movements of the rotating table are cyclically moved one after the other into three switch positions. In the first switch position -I, insulated cover tapes are laid, which serve to lock the stator slots after the windings are pulled. In the second switching position II, wire filaments are created, which are transmitted to a tension working .or-. Gun 2. In the third switching position III, turns 3 are pushed into active stator steel packages. The leash 6 rotates around the template 4 and forms 4 turns on the single-section multi-section template, which already during the winding process by means of short pullers 5, axially moving back and forth, are transmitted to the tensioning element 2 entering during winding with the template. The drive for pullers can serve as a shaking disc. A: During winding, the pattern 4 descends in a stepwise manner and penetrates deeper into the tensioning member 2, while the leash is constantly rotating in the same plane. During the entire winding process, the pullers remain at one and the same level and push one after another the individual turns of the different sections of the pattern 4 into different gaps between the rings, placed vertically, and the standing plates of the tension working body 2. After Separate sections of pattern 4: the specified number of turns is developed, pullers 5 must be known in an M way, while the pattern is engaged with the plastic and tensioner org. 2, move over the lower edge of the pattern 4 to reset lice with aa pattern coils. The wire supplied to the shelf 6 is wound up from the shoulder coil 9 with the wire located near the machine with a shoulder. A friend reserve backup wire coil 10 is already set in advance. If, when winding the wire reel of the coil 9, Kf is completely consumed, for example, the very rear end of the wire is detached from the free month: |: and the connection on the holder of the backup coil with wire 9, the machine stops and the welding coil 10 can start the backup coil 10 with wire the joint is welded to the end of the backup coil with wire 9. The welding site can be isolated, and the winding process can proceed further without threading the beginning of the wire of the backup coil 10 through flexible tubes and guide channels s leash until used. A particularly good joint between the two ends of the wire is reached when the welding device 11, before joining, is both opposite and connected to an overlapping wire, just like a press for gluing films, separated by a common cut at the same place, and then the cut points are welded together. If, when the clamping is cleared, the research institute moves the carriage 12, while, located on the frame of the machine or on the turntable, 1 bolt cages part 33 of the template and in the zhyat position, as a result of the interaction of the toothed racks 36 and 37 with the toothed wheel 38, the pattern portion 32 moves relative to the pattern portion 33 in the same direction, but to the double path of the carriage 1. As a result, the rotation of the leash 6 is achieved regardless of the width of the template as a whole maintains its central position relative to the template. At the same time, the bolt 44 used to release the clamping parts of the template provides the position of that part 33 of the template that engages with the tensioning body 2 during the winding process. Therefore, it is recommended to make a hole or recess 45 in the template part 33, very precisely to cross the transverse The cross section of the bolt 44 is arrested. The end plates 47 protrude approximately to the height of the stator active steel package on the free ends of the cover tape plates 48. If the tension workers. The bodies 2 are delivered to position under the winding pattern 4, this not only brings about the disadvantage of increasing the height of the structure of the machine, but also has, as was unexpectedly discovered, another disadvantage in that the plates 47 are as a result more easily bent to such an extent that the adjacent gaps between the plates are narrowed to a critical degree and as a result, the wire is trapped in the gaps. The clamping plates 47, during the winding and transfer process, are retracted, into the ring of cover tape plates 48, for example, 5-12 mm, from both presented tensioning members 2. Thus, the height of the structure is reduced, the width of the gap is more precisely maintained These plates have the advantage that, when removing the last turns from the pattern 4, the pullers 5 should perform only a relatively short way down in order to move all the turns up to the lower-plane of the free ends of the cover tape plates. Pushing the turns of the wire into the tension working body down to the ends of the cover tape plates 48 prevents the wires from tangling in the notched ends of the cover tape plates 48. In the winding device, the axial feed paths of the pattern 4, consisting of the leash b, the pullers 5 and the clamping and cutting mechanism 7, installed in such a way and coordinated in time with each other, that the pattern 4 during the winding process periodically penetrates the plates of the tension working body 2 to the required amount, then the pullers 5 do not lower, to First, up to the lower end of the pattern 4 pushed to its lowest position, but only a short section of the path is reached down to the lower ends of the cover tape plates 48. While the pullers 5 are kept at this level, the template 4 is pulled back upwards, and the pullers 5 drop the turns on the template 4 that remain on the tension body of the template 4. With this method of operation, the parts of the working body interacting during the removal process f are saved and improves the position of the turns of wire in the tensioning bodies. The axial drive pattern 4 is also used to bolt 44 /
    the arrest entered the hole 45. JWELL of the exact position, the arresting bolt 44 does not present any difficulty in replacing the template, as the SaK 44 arrest acts as a centering auxiliary.
