Description

Die Erfindung betrifft ein Nietgerät, hydraulisch betätigt oder als Handnietgerät mit zwei Gelenkhebeln zum Ausführen des eigentlichen Nietvorganges und eines in Drehung versetzbaren Gewindedorns zum Aufschrauben der Nietmutter und zum Herausschrauben nach dem Nietsetzvorgang.The invention relates to a riveting device, operated hydraulically or as a hand riveting device with two articulated levers for carrying out the actual riveting process and a rotating mandrel for screwing on the rivet nut and for unscrewing after the riveting process.

Mit derartigen Geräten läßt sich zwar ohne Schwierigkeiten ein Nietvorgang durchführen; es ist jedoch eine Vielzahl von Handgriffen erforderlich, die eine Belastung der Bedienungsperson darstellen, was bei längeren Arbeitszeiten zu Ermüdungserscheinungen führt, und außerdem erfordert die Durchführung der einzelnen Handgriffe einen großeren Zeitaufwand. So müssen zunächst die Hebelarme vollständig geöffnet werden, und der Gewindedorn ist in Drehung zu versetzen. Zu diesem Zweck ist es bekannt, daß ein Handknauf eines am Gewindedorn angebrachten Zugrohres zurückgeschoben wird, während die Einnietmutter zwischen Daumen und Zeigefinger am Gerätegehäuse auf den Gewindedorn aufgeschraubt wird. Der eigentliche Nietvorgang wird durchgeführt, indem die zwei Hebelarme nach innen zusammengedrückt werden. Danach erfolgt durch Betätigung des Zugrohres das Ausschrauben des Gewindedorns aus der Nietmutter. Um die Bedienung des Nietvorganges zu vereinfachen, ist es bereits bekannt, am Ende des Gewindedorns einen Elektromotor vorzusehen, der den Gewindedorn in Drehung versetzen kann. Der Elektromotor mit dem dazu erforderlichen Akku führt jedoch dazu, daß das Gerät ein verhältnismäßig großes Gewicht bekommt, so daß der Umgang mit dem Gerät dadurch erschwert wird und die Bedienungsperson verhältnismäßig viel Kraft aufzuwenden hat.With such devices, a riveting process can be carried out without difficulty; however, a large number of handles are required, which represent a burden on the operator, which leads to fatigue during longer working hours, and in addition, the execution of the individual handles requires a greater expenditure of time. First the lever arms have to be opened completely and the mandrel has to be set in rotation. For this purpose it is known that a hand knob of a pull tube attached to the threaded mandrel is pushed back while the rivet nut is screwed onto the threaded mandrel between the thumb and index finger on the device housing. The actual riveting process is carried out by pressing the two lever arms inwards. The threaded mandrel is then unscrewed from the rivet nut by actuating the pull tube. In order to simplify the operation of the riveting process, it is already known to provide an electric motor at the end of the threaded mandrel, which rotates the threaded mandrel can move. However, the electric motor with the required battery leads to the device being given a relatively large weight, so that handling of the device is thereby made more difficult and the operator has to use a relatively large amount of force.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Nietgerät verfügbar zu machen, das eine günstige Bedienung zur Durchführung des Nietvorgangs ermöglicht, bei der Ermüdungserscheinungen der Bedienungsperson sowie die Verarbeitungszeit herabgesetzt sind.The invention is therefore based on the object of making available a riveting device which enables inexpensive operation for carrying out the riveting process and in which the operator's signs of fatigue and the processing time are reduced.

Die Erfindung besteht darin, daß an dem dem Gewindedorn gegenüberliegenden, hinteren Ende des Gerätegehäuses eine Dreheinrichtung in Form eines Drehkopfes vorgesehen ist, der mit einer mit dem am vorderen Ende des Gerätegehäusees vorstehenden Gewindedorn verbundenen Zugspindel drehfest verbunden ist.The invention consists in that a rotating device in the form of a rotary head is provided at the rear end of the device housing opposite the threaded mandrel, which is connected in a rotationally fixed manner to a pulling spindle connected to the threaded mandrel projecting at the front end of the device housing.

Um den Kraftaufwand zu verringern, schlägt die Erfindung weiter vor, daß der Drehkopf das hintere Ende des Gerätegehäusees zylinderartig umgibt und mit einem Mitnehmer verbunden ist, der ein Getriebe antreibt, das am hinteren Ende der Zugspindel angeordnet ist.In order to reduce the expenditure of force, the invention further proposes that the rotary head surrounds the rear end of the device housing in a cylinder-like manner and is connected to a driver which drives a transmission which is arranged at the rear end of the tension spindle.

Zweckmäßig sind am Gerätegehäuse Drehmarkierungen angebracht.Rotational markings are expediently attached to the device housing.

Zur verbesserten Bedienung kann vorgesehen sein, daß der Drehkopf seitlich am Gerätegehäuse außerhalb der Ebene der Griffrohre angeordnet und über ein Zahnradgetriebe mit der Zugspindel verbunden ist. Dabei ist zweckmäßig vorgesehen, daß die Drehwelle des Drehkopfes in einer Ebene senkrecht zur Zugspindel verläuft und daß die Drehwelle ein Kegelzahnrad trägt, das mit einem auf der Zugspindel sitzenden Kegelzahnrad kämmt.For improved operation, it can be provided that the rotary head is arranged on the side of the device housing outside the plane of the handle tubes and is connected to the traction spindle via a gear mechanism. It is expediently provided that the rotary shaft of the rotary head runs in a plane perpendicular to the tension spindle and that the rotary shaft carries a bevel gear which meshes with a bevel gear seated on the tension spindle.

Gemäß einer vorteilhaften Ausführungsform ist der Drehkopf auf einer drehbar auf dem hinteren Ende des Gerätegehäusees sitzenden Hülse montiert, wobei die Hülse entsprechend der Art der Bedienung des Gerätes in verschiedenen Stellungen festlegbar ist.According to an advantageous embodiment, the rotary head is mounted on a sleeve rotatably seated on the rear end of the device housing, the sleeve can be set in different positions according to the type of operation of the device.

Dazu trägt mit Vorteil die Hülse einen Festlegebolzen, der in Ausnehmungen eingreift, die auf dem Gerätegehäuse angebracht sind. Es kann auch zweckmäßig vorgesehen sein, daß die Hülse urch einen Reibesitz auf dem Gerätegehäuse stufenlos in ihrer Drehstellung einstellbar ist.For this purpose, the sleeve advantageously carries a fixing bolt which engages in recesses which are made on the device housing. It can also be expediently provided that the sleeve is infinitely adjustable in its rotational position by a friction fit on the device housing.

Dieses Gerät kann von der Bedienungsperson an die Arbeitsweise angepaßt werden, ist verhältnismäßig leicht und ermöglicht eine erleichterte Bedienung. Das Gerät besitzt ein verhältnismäßig geringes Gewicht, ist kürzer als bekannte Geräte, dadurch besser handhabbar und zeichnet sich durch eine kompakte Bauweise aus. Es erfordert einen verhältnismäßig geringen Kraftaufwand.This device can be adapted to the working method by the operator, is relatively light and enables easier operation. The device has a relatively low weight, is shorter than known devices, therefore easier to handle and is characterized by a compact design. It requires relatively little effort.

Die Erfindung soll nachstehend anhand eines Ausführungsbeispiels unter Bezugnahme auf die beigefügten Zeichnungen näher erläutert werden.The invention will be explained below using an exemplary embodiment with reference to the accompanying drawings.

In den Zeichnungen zeigen:

Fig. 2
eine abgewandelte Darstellung der Dreheinrichtung im Schnitt für ein Gerät nach Fig. 1.
The drawings show:
Fig. 1
a hand riveter for blind rivet nuts in section;
Fig. 2
a modified representation of the rotating device in section for a device according to FIG. 1.

Bei dem in Fig. 1 dargestellten Handnietgerät für Blindnietmuttern steht der Gewindedorn 1 aus dem Mundstück 2 hervor, das mit Hilfe einer Kontermutter 3 befestigt ist. Die Gewindedornaufnahme 4 befindet sich in der vorderen Hülse 5, in der auch das Mundstück 2 festgelegt ist. Die Befestigung erfolgt mit einer hinteren Kontermutter 6. An dem vorderen Gerätegehäuse 7 sind die Griffrohre 8 der Hebel durch Bolzen 9 befestigt. Mit Hilfe eines Gewindebolzens 10 und einer Sicherungsmutter 11 ist das vordere Ende der Zangenschenkel 14 angelenkt, deren hinteres Ende mit Bolzen 9 am Gerät befestigt ist. Am vorderen Gehäuse 7 ist eine Hubstellschraube 13 mit O-Ring 12 angebracht. Durch das hintere Gehäuse 15 verläuft die Zugspindel 16. Am hinteren Gehäuse 15 ist mit Hilfe von Gewindestiften 17 eine Führungshülse 18 angebracht, in der ein Planetengetriebe 19 sitzt und durch die Gewindestifte 20 festgelegt ist. Von dem Planetengetriebe 19 erstreckt sich ein Mitnehmer 21, an dem ein Drehkopf 22 durch Gewindestifte 23 befestigt ist.In the hand riveter for blind rivet nuts shown in FIG. 1, the threaded mandrel 1 protrudes from the mouthpiece 2, which is fastened with the aid of a lock nut 3. The mandrel holder 4 is located in the front sleeve 5, in which the mouthpiece 2 is also fixed. It is fastened with a rear lock nut 6. The handle tubes 8 of the levers are fastened by bolts 9 to the front device housing 7. With the help of a threaded bolt 10 and a lock nut 11, the front end of the pliers legs 14 is articulated, the rear end of which is fastened to the device with bolts 9. On the front housing 7 is a lifting screw 13 with an O-ring 12 attached. The traction spindle 16 runs through the rear housing 15. A guide sleeve 18 is attached to the rear housing 15 with the aid of setscrews 17, in which a planetary gear 19 sits and is fixed by the setscrews 20. A driver 21 extends from the planetary gear 19, to which a rotary head 22 is fastened by means of threaded pins 23.

Beim Drehen des Drehkopfes 22 wird über den Mitnehmer 21 das Planetengetriebe 19 betätigt, das wiederum die Spindel 16 in Drehung versetzt. Auf diese Weise ist es möglich, durch Drehung des Drehkopfes 22 den Gewindedorn auf die Blindnietmutter aufzuschrauben und nach dem Nietsetzvorgang wieder herauszuschrauben.When turning the rotary head 22, the planetary gear 19 is actuated via the driver 21, which in turn sets the spindle 16 in rotation. In this way, it is possible to screw the mandrel onto the blind rivet nut by rotating the rotary head 22 and to unscrew it again after the rivet setting process.

In Fig. 2 ist eine abgewandelte Ausführungsform dargestellt. Auf dem Gerätegehäuse 14 sitzt eine Hülse 41, die in Bezug auf das Gerätegehäuse drehbar gestaltet ist. In der Hülse 41 ist eine Bohrung 42 vorgesehen, durch die ein nicht dargestellter Festlegebolzen in eine Ausnehmung 43 eingreift, die im Gerätegehäuse 40 vorgesehen ist. Durch eine Vielzahl über den Umfang verteilter Ausnehmungen 43 kann so die Hülse 41 in verschiedenen Stellungen in Bezug auf das Gerätegehäuse 40 festgelegt werden. Es ist aber auch möglich, einen Reibesitz vorzusehen, so daß die Hülse 41 stufenlos in Bezug auf das Gerätegehäuse 40 einstellbar ist. Mit der Hülse 41 kann somit auch ein seitlich auf dieser angebrachter Drehkopf in eine Lage relativ zum Gerätegehäuse 40 gebracht werden, wie es Umstände bei der Montage erforderlich machen oder wie es der Bedienungsperson am angenehmsten ist. Mit dem Drehkopf 44 ist ein Kegelzahnrad 45 verbunden, dessen Welle 46 senkrecht zur Zugspindel 16 verläuft.2 shows a modified embodiment. A sleeve 41 is seated on the device housing 14 and is designed to be rotatable with respect to the device housing. A bore 42 is provided in the sleeve 41, through which a fixing bolt (not shown) engages in a recess 43 which is provided in the device housing 40. The sleeve 41 can thus be fixed in various positions with respect to the device housing 40 by a plurality of recesses 43 distributed over the circumference. But it is also possible to provide a friction fit, so that the sleeve 41 is infinitely adjustable with respect to the device housing 40. With the sleeve 41, a rotary head attached laterally on this can also be brought into a position relative to the device housing 40, as may be required during assembly or as is most convenient for the operator. A bevel gear 45 is connected to the rotary head 44, the shaft 46 of which runs perpendicular to the feed spindle 16.

Die Zugspindel 16 ist mit einer Verlängerungsspindel 47 verbunden, die ein Kegelzahnrad 48 trägt, das mit dem Kegelzahnrad 45 der Welle 46 kämmt, mit der der Drehkopf 44 verbunden ist. Mit Hilfe eines nicht dargestellten Bolzens, der in einer Bohrung 49 im Drehkopf sitzt, ist dieser mit der Welle 46 drehfest verbunden. Auf diese Art und Weise kann mit Hilfe des seitlich angeordneten Drehkopfes 44 über die Zugspindel 16 der Dorn 1 gedreht werden, um die Gewindenietmutter aufzufädeln und nach dem Nietvorgang den Gewindedorn 1 herauszudrehen. Die Erfindung macht somit ein Gerät zum Setzen von Gewindenietmuttern verfügbar, bei dem die Drehung des Gewindedorns mit Hilfe des Gewindekopfes 22, 44 in einfacher Weise erfolgt und der Gewindekopf 44 in eine optimale Stellung gebracht werden kann.The traction spindle 16 is connected to an extension spindle 47 which carries a bevel gear 48 which meshes with the bevel gear 45 of the shaft 46 to which the rotary head 44 is connected. With the help of a bolt, not shown, which sits in a bore 49 in the rotary head, this is with the Shaft 46 non-rotatably connected. In this way, with the help of the laterally arranged rotary head 44, the mandrel 1 can be rotated via the pulling spindle 16 in order to thread the threaded rivet nut and to unscrew the threaded mandrel 1 after the riveting process. The invention thus makes available a device for setting threaded rivet nuts in which the rotation of the threaded mandrel takes place in a simple manner with the aid of the threaded head 22, 44 and the threaded head 44 can be brought into an optimal position.
