Известен механизм дл равномерной укладки проволоки на катушку намоточного устройства, состо щий из каретки с направл юш .ими роликами, ходового винта и переключател , выполненного в виде цилиндрической втулки с размешенными в ней подпружиненными толкател ми, где втулка св зана с зашелкой и фиксатором, установленным на каретке I.A known mechanism for evenly placing the wire on the coil of the winding device, consisting of a carriage with directional rollers, a lead screw and a switch, is made in the form of a cylindrical sleeve with spring-loaded pushers placed in it, where the sleeve is connected to a spindle and retainer installed on carriage I.

Однако этот механизм не может надежно переключа.ть реверс раскладки, так как зашелка при переключении, выйд из зацеплени с одной гайкой, может попасть на зуб другой гайки (не во впадину) и остановить гайку.However, this mechanism cannot reliably switch the reversal of the pickup, since a slip when switching, disengaging from one nut, can get onto the tooth of another nut (not into the cavity) and stop the nut.

Изйестен также механизм дл изменени направлени перемещени узла раскладки намоточного устройства, содержащий корпус , расположенные в корпусе ходовой винт, штангу и двухстороннюю кулачковую полумуфту установленную на ходовом .винте 2.A mechanism for changing the direction of movement of the pickup assembly of the winding device is also iestable, comprising a housing, a lead screw located in the housing, a rod and a double-sided cam coupling half mounted on the threaded screw 2.

Однако существенным недостатком эт го механизма вл етс то, что при полом пружины или при выт жке ее, когда си. пружины недостаточна дл переключени механизма, каретка продолжает двигать в первоначальном направлении, что привHowever, a significant disadvantage of this mechanism is that with a hollow spring or when it is pulled out, when b. the springs are insufficient to switch the mechanism, the carriage continues to move in the original direction, which

The swing of the lever 1 is limited by a stop made in the form of a nut 4 and a lock nut 5, which are threadedly connected to a rod 3, which is housed in the bearings of the winding device 6. The middle part of the lever 1 has a projection 7 with two bevels, which interacts with a node for changing the node position of the lever, made in the form of a protrusion 8 with two bevelings of the bar 9. One end (bar 9 is pivotally connected by axis 10 to the body 6, and the other end through a spring 11 is connected to the base of the housing 6. The lower end of the lever 1 is placed in the groove of the coupling half 12 mounted on the lead screw 13 so that it can only move along the screw in the axial direction. The coupling half 12 can be connected in extreme positions with the coupling half 14 and 15. Half coupling 14 hard associated with the bevel gear 16 and coupling half 15 rigidly associated with the bevel gear 17 and a pinion 18, mounted on the screw 13 rotatably.

Намоточное устройство (фиг. 3), в котором используетс данный механизм, имеет iKaретку 20, перемещающуюс возвратно-поступательно по штангам 21, жестко закрепленным в корпусе 6. Каретка 20 имеет ролики 22 и приводитс в движение с помощью гайки 23 и винта 13. В крайних положени х каретка 20 взаимодействует через пружины 24 и 25 с упорами 26 и 27, жестко закрепленными на штанге 3. В подшипниках корпуса 6 установлены вращающиес конусы 28 и 29, в которых устанавливаетс катушка 30. На корпусе 28 жестко закреплена шестерн 31, котора находитс в посто нном зацеплении с шестерней 18. На катушку наматыJ ваетс проволока 32, направл ема роликами 22 каретки 20. The lag time of which is located in the housing 6. The winding device (Fig. 3), in which this mechanism is used, has an iKracket 20, moving reciprocating along rods 21 rigidly fixed in the housing 6. The carriage 20 has rollers 22 and is driven by means of a nut 23 and a screw 13. In the extreme positions, the carriage 20 interacts through springs 24 and 25 with stops 26 and 27 rigidly mounted on the rod 3.

Механизм работает следуюшим образом. На фиг. 1-3 показано положение механизмов , когда включена полумуфта 12 сThe mechanism works as follows. FIG. 1-3 shows the position of the mechanisms when the half-coupling is switched on 12 s

0 полумуфтой 15 и каретка перемещаетс . Выступ 8 планки 9 давит (силой пружины 11) на скос выступа 7 рычага 1 и посто нно прижимает полумуфту 12 к полумуфте 15. Другим концом рычаг 1 стремитс прижи .мать штангу 3 вправо, но упор 4 преп тствует повороту рычага 1 на оси 2, и сдвиг штанги 3 ограничиваетс ходом включени полумуфты 12 и полумуфтой 15. Этим исключаетс произвольное выключение полумуфты 12. После заправки проволокой 320 by the coupling half 15 and the carriage moves. The protrusion 8 of the bar 9 presses (force of the spring 11) on the bevel of the protrusion 7 of the lever 1 and constantly presses the coupling half 12 to the coupling half 15. At the other end, the lever 1 tends to press the rod 3 to the right, but the stop 4 prevents the lever 1 from turning on the axis 2, and the shift of the rod 3 is limited by the course of engagement of the coupling half 12 and the coupling half 15. This precludes the arbitrary switching off of the coupling half 12. After refueling with wire 32

0 катушка 30 приводитс во вращение от конуса 29 (привод не показан). Катушка 30 через шестерни 31 и 18 сообщает вращение в разные стороны полумуфтам 14 и 15, которые (в зависимости от включени ) привод т во врац}.ение ходовой винт 13. В данном положении каретка 20, приводима в движение от ходового винта 13 через гайку 23, перемещаетс влево. Дойд до пружины 24 и сжав ее, каретка начинает двигать штангу 3 влево (по стрелке Б) через упор 26.0, the coil 30 is driven to rotate from a cone 29 (drive not shown). The coil 30, through gears 31 and 18, communicates rotation in different directions to coupling halves 14 and 15, which (depending on switching on) drive the screw screw 13. In this position, the carriage 20 is driven from the screw screw 13 through the nut 23, moves to the left. After reaching the spring 24 and squeezing it, the carriage begins to move the rod 3 to the left (according to arrow B) through the stop 26.

Claims

The lever 1 begins to rotate around the end abutting the half coupling 12, and the protrusion 7 slides along the protrusion 8, starts to raise the bar 9. The lever 1 rotates until it rests against the upper end against the stop 4 (Fig. 4), after which it continues to move along with the rod 3, forcibly uncoupling the coupling half 12 with the coupling half 15. Before meeting the tops of the projections 7 and 8, the spring 11 through the bar 9 and the projections 7 and 8 presses on the lever 1, which prevents the coupling of the coupling half 12 with the half-coupling 15. After meeting the tops of the projections 7 and 8 ( Fig. 4) the coupling half 12 does not go completely out of the hook Yeni with half coupling; the rod 3 continues to move, striving to forcibly disengage the coupling half 12 and 15. When meeting the peaks of the projections, the spring does not affect the switching, and the force of the friction into the teeth and the coupling half under load is significant. At the moment when the teeth of the coupling halves (Fig. 5) exit, the load drops sharply, the tops of the projections 7 and 8 are on opposite bevels of the projections; the strap 9 (with the help of the spring I), the protrusion 8 acts on the protrusion 7, jumps to the left with the lever 1 to the coupling half 12, turning on with the coupling half 14 (Fig. 6). It is possible that the teeth of the coupling halves 12 and 14 are upset with the ends of the teeth. Then a constant pressure is applied to the teeth from the spring 11. If the friction force between the ends of the teeth is sufficient to drive the screw 13, then the layout also remains operable. If the frictional force is not enough to drive the screw 13, then the teeth of the half coupling 12 under the action of the spring 11 and the bevels of the ridges 8 and 7 will slide along the ends of the half coupling 14 and enter the hollows, rigidly adhering. The rotation direction of the screw 13 is changed, and the carriage 20 will receive a reverse movement (to the right). Iolumufta 12 is constantly pressed against the half coupling 14 (preventing the shutdown) of the prudina 11 through the protrusions 8 and 7 with the lever 1. When switching, the carriage 20 meets the stop 27 to ensure that the backslide passes when the projections meet. and with it begins to move the bar 3 (along the arrow B) to the right. The rod 3, moving, begins to turn the lever 1 around the end connected to the coupling half 12, before the lever 1 stops 4 (the end of the lever 1 exerts pressure on the coupling half 12 by means of the spring 11 through the bevels of the ridges 8 and 7, preventing the coupling halves 12 and 14). After that, the lever 1 moves together with the rod 3, forcibly pulling the teeth of the coupling half 12 out of the teeth of the coupling half 14. During the further course of the apex, the projections 7 and 8 meet (Fig. 8). The rod 3 continues to move along the arrow B from the carriage 20, since the coupling half 12 is not turned off with the coupling half 14. Then the tops of the ridges 8 and 7 pass through the opposite position. The rod 3 then turns off the coupling half 12- (Fig. 9). The load between the teeth disappears, and the spring 11, acting on the bar 9 through the ridges 8 and 7, abruptly rotates the lever 1 around the axis 2 and turns on the coupling half) 12 with the coupling half 15 (Fig. 10 and 1) - will reverse the screw 13. Next cycles are repeated. Offset stop 4 adjusts | ts position of the meeting of the tops of the ridges 8 and 7 and the degree of engagement of the teeth of the coupling half after meeting the tops of the ridges. The mechanism of this design makes it possible to switch in one constant extreme position by forcibly turning off the half-coupling, which improves the quality of the wire winding on the cut near the cheeks; increase the reliability of the nepei because the shutdown is forced and the reverse is activated by a spring with relative protrusions (during friction it is therefore not necessary to install a spring of increased rigidity to guarantee the connection; in case of meeting the teeth the field remains capable, so as in the process of the spring, they are constantly trying to turn them on; if the spring breaks or is pulled out, the possibility of forcibly disconnecting the carriage and stopping the cage, because the spring force is insufficient Mula of the invention 1. A mechanism for changing the direction of movement of the pickup assembly of the winding device, comprising a housing, a lead screw disposed in the housing, pieces and a double-sided cam half mounted on the lead screw, different in order to increase the performance of the folding mechanism and At the quality of wire laying on the coil cheeks, it is equipped with a mortar lever connected to the rod and a half-body node for changing the angular position of the lever connected to the lever in its first part by lever stops placed on the rod e. 2.
