Definitions
- the invention relates to a device for straightening protruding wire ends of enamelled copper wires of a coil arrangement of electric motors.
- a device for inserting cable ends into circuit boards has become known, in which a gripper which can be moved parallel to the axial direction of the cable end holds the cable end on an insulation and a pliers-like straightening tool straightens the non-insulated tip of the cable end. The pliers-like straightening tool then moves apart and the cable is guided into the circuit board by the gripper. Straightening protruding wire ends of enamelled copper wires is not possible with a gripper that can be moved parallel to the axial direction of the wire end.
- the JP S 61 22236 U discloses a device for soldering a component to a circuit board.
- JP S60 255224 A discloses a slider with a slot-like recess for supporting a wire end of a coil. The slider is pushed over the end of the wire with the slot-like recess and then a mold plate is guided into the recess to shape the end of the wire. This device is only suitable for very stiff wire ends, where bending away when the slider moves is impossible.
- the invention is based on the problem of creating a device with which an additional component that has to be assembled is avoided and with which damage to the wire ends can be avoided.
- a clamping device for clamping the wire ends at a distance from their free ends and a straightening device for straightening the free ends of the wire ends that protrude above the clamping device.
- the wire ends are initially held by the clamping device at a distance from their free ends.
- Appropriate design of the clamping device prevents damage, particularly to enamelled copper wires. Then leave it The free ends of the wire ends are aligned by the straightening device and thus brought into the intended shape. This means that the wire ends are brought into the intended shape without the use of additional components.
- the motor assembly having the coil arrangement can then be inserted into the injection molding tool.
- the device is particularly compact if the clamping device and the straightening device are arranged in two levels one above the other.
- An electric motor usually has at least two wire ends that need to be straightened.
- the device enables rapid processing of several wire ends if the clamping device and the straightening device are designed for simultaneous clamping and straightening of several wire ends.
- the clamping device has two clamping elements that can be moved relative to one another between a clamping position and a release position and that wire ends inserted in the clamping position are held in a non-positive manner and in the release position The frictional connection with the inserted wire ends is released.
- uniform clamping of the wire ends can be ensured if the clamping elements are each connected to an actuator and can be moved transversely to the axis of the wire ends.
- the straightening of the wire ends is particularly simple if the straightening device has two straightening elements that can be moved relative to one another between a straightening position for bending or straightening the wire ends and a release position. To When processing several wire ends at the same time, the straightening elements can be shaped accordingly.
- one of the straightening elements could be fixed and the other of the straightening elements could be moved.
- this can lead to undesirable stress on the wire ends.
- the load on the wire ends can be kept particularly low if the two straightening elements are each connected to an actuator and can be moved transversely to the axis of the wire ends. Due to this design, the straightening elements move towards each other and straighten the end of the wire, which is preferably held centrally by the clamping device.
- lateral bending of the wire ends during straightening can be easily avoided if the straightening elements are designed prism-shaped. This design guides the wire end into the intended shape.
- the device can be easily converted for multiple wire ends, different shapes or for different cross sections of the wire ends if the straightening elements are releasably fastened in the straightening device.
- This design makes it possible to replace the straightening elements and thus adapt the straightening device to the number, the shape to be straightened and the cross section of the wire ends.
- a screw connection is particularly suitable for detachable fastening.
- the actuators for driving the straightening elements and the clamping elements can be arranged on one side if one of the straightening elements and one of the clamping elements are connected to the respective actuator via tie rods. Due to this design, the device projects laterally beyond the coil arrangement, so that if there are several wire ends to be straightened, several devices are connected to one another can be coupled. This also makes the device particularly compact.
- Figure 1 shows a straightening tool with three interconnected devices 1 and a coil arrangement 2.
- the devices are used to straighten wire ends 3 of the coil arrangement 2 before inserting the coil arrangement 2 into an injection molding tool.
- the devices 1 are connected to one another via a ring carrier 4 and can be pushed along several vertical guide columns 5 onto the wire ends 3 projecting from the coil arrangement 2, so that each of the devices 1 accommodates two wire ends 3.
- the devices 1 are each used to simultaneously clamp and straighten two wire ends 3.
- the coil arrangement 2 is part of a stator, not shown Small electric motor, which is often used as a servomotor in today's motor vehicles.
- FIG 2 shows one of the devices 1 Figure 1 in a perspective view.
- the device 1 has a clamping device 6 and a straightening device 7.
- the clamping device 6 serves to clamp the wire ends 3 at a distance from their free ends, while the straightening device 7 is arranged sandwich-like above the clamping device 6 and is designed to straighten the free ends of the wire ends 3 .
- the clamping device 6 and the straightening device 7 thus lie in two levels one above the other and each have two actuators 8 - 11 for driving clamping elements 12, 13 and straightening elements 14, 15.
- the actuators 8, 9 of the clamping device 6 are in Figure 3 visible in a top view.
- the actuators 8 - 11 are designed as double-acting pneumatic cylinders and enable the clamping elements 12, 13 of the clamping device 6 and the straightening elements 14, 15 of the straightening device 7 to move towards one another.
- the actuators 8 - 11 designed as pneumatic cylinders enable the clamping elements 12, 13 or the directional elements 14, 15 to be actively moved away from one another and actively moved towards one another transversely to the in Figure 1 shown axes of the wire ends 3.
- the wire ends 3 are thus held in a non-positive manner in a defined position when the clamping elements 12, 13 move towards one another and can be directed into the desired shape by the straightening elements 14, 15. Subsequently, straightening elements 14, 15 and clamping elements 12, 13 are moved away from each other and the coil arrangement 2 can be removed from the straightening tool with the straightened wire ends 3.
- Figure 3 shows a top view of the device 1 Figure 1 that in the straightening device 7, the actuator 10 close to the straightening elements 14, 15 is connected directly to one of the straightening elements 14, while the actuator 11 far from the straightening elements 14, 15 is connected to the second straightening element 15 via tie rods 16.
- the directional elements 14, 15 are prism-shaped and releasably attached to the straightening device 7. This means that the straightening device 7 can be converted, for example, to straighten a single wire end 3 or three wire ends 3 by replacing the straightening elements 14, 15.
- Figure 4 shows in a side view of the device 1 that the clamping device 6 is constructed analogously to the straightening device 7 and also has tie rods 17 for connecting the one actuator 9 to the one clamping element 13. Furthermore, the clamping device 6 and the straightening device 7 each have adjusting screws 18, 19 for adjusting stops (not shown) of the clamping element 13 and straightening element 15 connected to the tie rods 16, 17.
- Figure 5 shows a central sectional view through the device 1 Figure 3 along the line V - V. It can be seen here that the straightening elements 14, 15 mesh with one another like a comb. This means that the wire ends 3 are guided into the intended shape.
- the clamping elements 12, 13 have small dimensions compared to the straightening elements 14,15.
- Figure 6 shows a side sectional view through the device 1 for clarity Figure 3 along line VI - VI in the area of tie rods 16, 17.

Description
Die Erfindung betrifft eine Vorrichtung zum Richten von abstehenden Drahtenden von Kupferlackdrähten einer Spulenanordnung von Elektromotoren.The invention relates to a device for straightening protruding wire ends of enamelled copper wires of a coil arrangement of electric motors.
Insbesondere bei Kleinmotoren, wie sie häufig in Kraftfahrzeugen eingesetzt werden, werden zur Erstellung einer Motorbaugruppe Spulen mit abstehenden Drahtenden für einen Spritzgussvorgang in ein Spritzgießwerkzeug eingelegt. Weil sich verbogene Drahtenden nicht in das Spritzgusswerkzeug einlegen lassen, wird von Hand ein glockenförmiges Bauteil über die Drahtenden geschoben. Dieses glockenförmige Bauteil richtet die Drahtenden und hält diese in einer vorgesehenen Position. Nachteilig hierbei ist, dass das glockenförmige Bauteil ein zusätzlich zu fertigendes Bauteil ist und einen eigenen Montageschritt erfordert.Particularly in the case of small engines, such as those often used in motor vehicles, coils with protruding wire ends are inserted into an injection molding tool for an injection molding process to create an engine assembly. Because bent wire ends cannot be inserted into the injection molding tool, a bell-shaped component is pushed over the wire ends by hand. This bell-shaped component aligns the wire ends and holds them in a designated position. The disadvantage here is that the bell-shaped component is an additional component to be manufactured and requires its own assembly step.
Man könnte daran denken, die Drahtenden mittels einer Zange zu richten. Dies würde jedoch zu Beschädigungen der Drahtenden, insbesondere des Lacks bei Kupferlackdrähten führen.You could think of straightening the wire ends using pliers. However, this would lead to damage to the wire ends, especially to the paint on enamelled copper wires.

Die gattungsgemäße
Der Erfindung liegt das Problem zugrunde, eine Vorrichtung zu schaffen, mit der ein zusätzlich zu montierendes Bauteil vermieden wird und mit welchem eine Beschädigung der Drahtenden vermieden werden kann.The invention is based on the problem of creating a device with which an additional component that has to be assembled is avoided and with which damage to the wire ends can be avoided.
Dieses Problem wird erfindungsgemäß gelöst durch eine Klemmvorrichtung zum Klemmen der Drahtenden mit Abstand zu deren freien Enden und eine Richtvorrichtung zum Richten der über der Klemmvorrichtung überstehenden freien Enden der Drahtenden.This problem is solved according to the invention by a clamping device for clamping the wire ends at a distance from their free ends and a straightening device for straightening the free ends of the wire ends that protrude above the clamping device.
Durch diese Gestaltung werden die Drahtenden mit Abstand zu deren freien Enden von der Klemmeinrichtung zunächst gehalten. Durch eine entsprechende Gestaltung der Klemmeinrichtung werden Beschädigungen insbesondere bei Kupferlackdrähten vermieden. Anschließend lassen sich die freien Enden der Drahtenden von der Richteinrichtung richten und damit in eine vorgesehene Form bringen. Damit werden ohne Einsatz von weiteren Bauteilen die Drahtenden auf eine vorgesehene Form gebracht. Die die Spulenanordnung aufweisende Motorbaugruppe lässt sich anschließend in das Spritzgusswerkzeug einsetzen. Die Vorrichtung gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kompakt, wenn die Klemmvorrichtung und die Richtvorrichtung in zwei übereinander liegenden Ebenen angeordnet sind.With this design, the wire ends are initially held by the clamping device at a distance from their free ends. Appropriate design of the clamping device prevents damage, particularly to enamelled copper wires. Then leave it The free ends of the wire ends are aligned by the straightening device and thus brought into the intended shape. This means that the wire ends are brought into the intended shape without the use of additional components. The motor assembly having the coil arrangement can then be inserted into the injection molding tool. According to another advantageous development of the invention, the device is particularly compact if the clamping device and the straightening device are arranged in two levels one above the other.
Meist hat ein Elektromotor zumindest zwei Drahtenden, welche gerichtet werden müssen. Die Vorrichtung ermöglicht gemäß einer anderen vorteilhaften Weiterbildung der Erfindung eine schnelle Bearbeitung mehrerer Drahtenden, wenn die Klemmvorrichtung und die Richtvorrichtung zum gleichzeitigen Klemmen und Richten von mehreren Drahtenden ausgebildet sind.An electric motor usually has at least two wire ends that need to be straightened. According to another advantageous development of the invention, the device enables rapid processing of several wire ends if the clamping device and the straightening device are designed for simultaneous clamping and straightening of several wire ends.
Eine Fixierung der Drähte beim Richten der Drahtenden gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Klemmvorrichtung zwei zwischen einer Klemmstellung und einer Freigabestellung relativ zueinander verfahrbare Klemmelemente hat und dass in der Klemmstellung eingelegte Drahtenden kraftschlüssig gehalten sind und in der Freigabestellung ein Kraftschluss mit eingelegten Drahtenden gelöst ist.Fixing the wires when straightening the wire ends is particularly easy according to another advantageous development of the invention if the clamping device has two clamping elements that can be moved relative to one another between a clamping position and a release position and that wire ends inserted in the clamping position are held in a non-positive manner and in the release position The frictional connection with the inserted wire ends is released.
Ein gleichmäßiges Einklemmen der Drahtenden lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung sicherstellen, wenn die Klemmelemente jeweils mit einem Aktor verbunden sind und quer zur Achse der Drahtenden verfahrbar sind. Das Richten der Drahtenden gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Richtvorrichtung zwei zwischen einer Richtstellung zur Biegung oder zum Richten der Drahtenden und einer Freigabestellung relativ zueinander verfahrbare Richtelemente hat. Zur gleichzeitigen Bearbeitung mehrerer Drahtenden können die Richtelemente entsprechend geformt sein.According to another advantageous development of the invention, uniform clamping of the wire ends can be ensured if the clamping elements are each connected to an actuator and can be moved transversely to the axis of the wire ends. According to another advantageous development of the invention, the straightening of the wire ends is particularly simple if the straightening device has two straightening elements that can be moved relative to one another between a straightening position for bending or straightening the wire ends and a release position. To When processing several wire ends at the same time, the straightening elements can be shaped accordingly.
Im konstruktiv einfachsten Fall könnte eines der Richtelemente feststehend und das andere der Richtelemente verfahrbar sein. Dies kann jedoch zu einer unerwünschten Belastung der Drahtenden führen. Die Belastung der Drahtenden lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders gering halten, wenn die beiden Richtelemente jeweils mit einem Aktor verbunden und quer zur Achse der Drahtenden verfahrbar sind. Durch diese Gestaltung bewegen sich die Richtelemente aufeinander zu und richten das vorzugsweise mittig von der Klemmvorrichtung gehaltene Drahtende.In the simplest structural case, one of the straightening elements could be fixed and the other of the straightening elements could be moved. However, this can lead to undesirable stress on the wire ends. According to another advantageous development of the invention, the load on the wire ends can be kept particularly low if the two straightening elements are each connected to an actuator and can be moved transversely to the axis of the wire ends. Due to this design, the straightening elements move towards each other and straighten the end of the wire, which is preferably held centrally by the clamping device.
Ein seitliches Abknicken der Drahtenden beim Richten lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die Richtelemente prismenförmig gestaltet sind. Durch diese Gestaltung wird das Drahtende in die vorgesehene Form geführt.According to another advantageous development of the invention, lateral bending of the wire ends during straightening can be easily avoided if the straightening elements are designed prism-shaped. This design guides the wire end into the intended shape.
Die Vorrichtung lässt sich gemäß einer anderen vorteilhaften Weiterbildung einfach für mehrere Drahtenden, unterschiedliche Formen oder für unterschiedliche Querschnitte der Drahtenden umrüsten, wenn die Richtelemente lösbar in der Richtvorrichtung befestigt sind. Diese Gestaltung ermöglicht das Auswechseln der Richtelemente und damit die Anpassung der Richtvorrichtung auf die Anzahl, die zu richtende Form und den Querschnitt der Drahtenden. Zur lösbaren Befestigung eignet sich insbesondere eine Verschraubung.According to another advantageous development, the device can be easily converted for multiple wire ends, different shapes or for different cross sections of the wire ends if the straightening elements are releasably fastened in the straightening device. This design makes it possible to replace the straightening elements and thus adapt the straightening device to the number, the shape to be straightened and the cross section of the wire ends. A screw connection is particularly suitable for detachable fastening.
Die Aktoren zum Antrieb der Richtelemente und der Klemmelemente lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung auf einer Seite anordnen, wenn eines der Richtelemente und eines der Klemmelemente über Zugstangen mit dem jeweiligen Aktor verbunden sind. Durch diese Gestaltung überragt die Vorrichtung die Spulenanordnung seitlich, so dass bei mehreren zu richtenden Drahtenden mehrere Vorrichtungen miteinander gekoppelt werden können. Die Vorrichtung gestaltet sich hierdurch zudem besonders kompakt.According to another advantageous development of the invention, the actuators for driving the straightening elements and the clamping elements can be arranged on one side if one of the straightening elements and one of the clamping elements are connected to the respective actuator via tie rods. Due to this design, the device projects laterally beyond the coil arrangement, so that if there are several wire ends to be straightened, several devices are connected to one another can be coupled. This also makes the device particularly compact.
