Description

Die vorliegende Erfindung betrifft ein Werkzeug mit einem Antriebswerkzeug zum Festziehen oder zum Lösen von Kabel-Verschraubungen mit rundem Querschnitt, wobei die Längsachse des Antriebswerkzeuges im Anwendungsfalle parallel zur Längsachse eines zu verschraubenden Bauteiles verläuft.The present invention relates to a tool with a drive tool for tightening or loosening cable glands with a round cross-section, wherein the longitudinal axis of the drive tool in the application case runs parallel to the longitudinal axis of a component to be screwed.

Bei sogenannten Kabel-Verschraubungen, beispielsweise bei der Verschraubung von SAI-Leitungen mit im Querschnitt runden Schraubhülsen sind in der Praxis von einem entsprechenden Werkzeug zwei Forderungen zu erfüllen.In so-called cable glands, for example in the screw connection of SAI lines with round cross-section screw sleeves are in practice by a corresponding tool to meet two requirements.

Zum einen muß das Werkzeug seitlich bzw. quer zur Längsachse einer Schraubhülse an diese ansetzbar und so beschaffen sein, daß ein Drehmoment auf die Schraubhülse übertragen werden kann.Firstly, the tool must laterally or transversely to the longitudinal axis of a threaded sleeve attachable to this and be such that a torque can be transmitted to the threaded sleeve.

Zum anderen muß das Werkzeug so beschaffen sein, daß lediglich ein geringer Freiraum im Umgebungsbereich der Schraubhülse genügt, um diese festzuziehen oder bei Bedarf auch zu lösen, da häufig eine Vielzahl derartiger Verschraubungen achsparallel zueinander vorhanden ist, so daß für die Verwendung von schraubenschlüsselartigen Werkzeugen kein Raum ist.On the other hand, the tool must be such that only a small clearance in the surrounding area of the screw is sufficient to tighten or if necessary also to solve, since often a plurality of such fittings axially parallel to each other is present, so that no for the use of wrench-like tools Space is.

Aus der US-A-2 712 764 ist ein Werkzeug mit den Merkmalen des Gattungsbegriffes bekannt, welches zwar schon den Vorteil bietet, dass das Antriebswerkzeug im Anwendungsfalle parallel zur Achse eines verschraubenden Bauteiles verläuft, wodurch schon der Einsatz unter beengten Platzverhältnissen bedeutend verbessert wird, welches andererseits aber nur von oben auf ein zu verschraubendes Bauteil aufgeschoben werden kann, was insbesondere bei Anordnungen, bei denen viele Kabelverschrauben eng nebeneinander liegen, sehr hinderlich sein kann.From the US-A-2 712 764 is a tool with the features of the generic term is known, which indeed already has the advantage that the drive tool runs in the application case parallel to the axis of a screwing component, which already the use under cramped conditions is significantly improved, on the other hand, but only from the top of a too screwing component can be postponed, which can be very cumbersome especially in arrangements where many cable screws are close together.

Aus der US-A-2 649 824 ist ein Werkzeug zum Verschrauben von runden Bauteilen bekannt, welches rohrzangenähnlich aufgebaut ist. Dabei weist dieses Werkzeug zwei gegeneinander verschwenkbare Schenkel auf, von denen einer eine Aufnahme für ein zu verschraubendes rundes Bauteil und der andere Schenkel ein Druckstück bildet, mittels dessen das zu verschraubende Bauteil an zwei winklig zueinander verlaufende Anlageflächen des ersten Schenkels anpressbar ist. Die Längsachse des Antriebswerkzeuges verläuft im Anwendungsfall lotrecht zur Längsachse des zu verschraubenden Bauteiles, so dass bei entsprechender Länge des Antriebswerkzeuges ein entsprechender Hebelarm gebildet ist, der eine feste Einklemmung des zu verschraubenden Bauteiles im eigentlichen Werkzeug ermöglicht und somit auch hohe Kräfte beim Anziehen oder Lösen erreichbar sind. Ein derartiges Werkzeug wäre aber für das Festziehen oder Lösen von Kabel-Verschraubungen schon allein aufgrund des hohen Platzbedarfes nicht einsetzbar.From the US-A-2 649 824 is a tool for screwing round components known, which is constructed like a pipe wrench. In this case, this tool has two mutually pivotable legs, one of which forms a receptacle for a screwed round component and the other leg a pressure piece, by means of which the component to be screwed can be pressed against two mutually angled abutment surfaces of the first leg. The longitudinal axis of the drive tool extends in the application perpendicular to the longitudinal axis of the component to be screwed, so that with appropriate length of the drive tool, a corresponding lever arm is formed, which allows a firm entrapment of the component to be screwed in the actual tool and thus high forces when tightening or loosening reached are. Such a tool would not be used for tightening or loosening cable glands alone due to the high space requirements.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Werkzeug der gattungsgemäßen Art zu schaffen, welches sich durch einen einfachen Aufbau einerseits und durch einen äußerst geringen Platzbedarf für seine Betätigung andererseits auszeichnet.The present invention has for its object to provide a tool of the generic type, which is characterized by a simple structure on the one hand and by an extremely small footprint for its operation on the other hand.

Diese Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst.This object is solved by the subject matter of claim 1.

Ein derartiges Werkzeug weist einen einfachen und aus wenigen Einzelteilen bestehenden Aufbau auf und zeichnet sich andererseits durch nur einen geringen Platzbedarf für seine Betätigung aus.Such a tool has a simple and consisting of a few parts construction and on the other hand characterized by only a small footprint for its operation.

Die maulschlüsselartige, runde Aufnahme ermöglicht das seitliche Ansetzen des Werkzeuges auf ein zu verschraubendes oder zu lösendes rundes Bauteil. Der Klemmabschnitt des Knebels kann durch ein entsprechendes Antriebs-Werkzeug gegenüber dem Bügelteil gedreht und somit an das zu verschraubende oder zu lösende Bauteil angeklemmt werden. Hierdurch wird eine Drehmomentübertragung ohne weiteres möglich.The spanner-like, round recording allows the lateral attachment of the tool to a screwed or to be solved round component. The clamping portion of the toggle can be rotated by a corresponding drive tool relative to the bracket part and thus clamped to the component to be screwed or to be loosened. As a result, a torque transmission is readily possible.

Durch das Antriebs-Werkzeug kann dann das gesamte Bügelteil mit dem angeklemmten, zu verschraubenden oder zu lösenden Bauteil um dessen Längsachse verdreht werden, ohne daß hierfür ein größerer Platzbedarf vonnöten ist. Somit können auch eng beieinander liegende Kabel-Verschraubungen bequem festgezogen oder auch gelöst werden.By the drive tool, the entire bracket part with the clamped, to be screwed or to be loosened component can then be rotated about its longitudinal axis, without the need for a larger footprint is required. Thus, even tight cable glands can be tightened or loosened comfortably.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen.Further features of the invention are the subject of dependent claims.

In den Zeichnungen ist mit dem Bezugszeichen 1 jeweils insgesamt ein Werkzeug zum Festziehen oder zum Lösen von Kabel-Verschraubungen - wie in Figur 4 dargestellt - bezeichnet. Das Werkzeug 1 benötigt zu seiner Betätigung ein Antriebs-Werkzeug 2, welches, wie Figur 3 zeigt, eine Schraubendreherform aufweist.In the drawings, the reference numeral 1 in each case a total of a tool for tightening or loosening cable glands - as in FIG. 4 represented - designated. The tool 1 requires for its operation a drive tool 2, which, as FIG. 3 shows, having a screwdriver shape.

Das erfindungsgemäße Werkzeug 1 besteht aus einem Bügelteil 3 mit einer maulschlüsselartigen, im wesentlichen runden Aufnahme 4 zur Aufnahme eines zu verschraubenden, runden Bauteiles, beispielsweise einer Schraubhülse 5. Benachbart der Aufnahme 4 ist das Bügelteil 3 mit einem drehbar gelagerten Knebel 6 mit einem Klemmabschnitt 7 versehen, wobei der Klemmabschnitt 7 teilweise in die Aufnahme 4 hineinragt.The tool 1 according to the invention consists of a bracket part 3 with a spanner-like, substantially round receptacle 4 for receiving a screwed, round component, such as a screw 5. Adjacent to the receptacle 4 is the bracket part 3 with a rotatably mounted knob 6 with a Clamping section 7 is provided, wherein the clamping portion 7 protrudes partially into the receptacle 4.

Der Klemmabschnitt 7, der in seinem in die Aufnahme 4 hineinragenden Bereich eine kreisbogenförmige oder spiralförmige Außenkontur aufweist, ist bezogen auf diese Außenkontur exzentrisch zum Drehpunkt 8 des Knebels 6 angeordnet.The clamping portion 7, which has a circular arc-shaped or spiral-shaped outer contour in its region projecting into the receptacle 4, is arranged eccentrically with respect to this outer contour to the pivot point 8 of the toggle 6.

Der Knebel 6 ist mit einem im dargestellten Ausführungsbeispiel quadratischen Durchbruch 9 zur Aufnahme des Mitnehmerzapfens 10 des Antriebs-Werkzeuges 2 ausgestattet. Wesentlich ist, daß der Durchbruch 9 einen unrunden Querschnitt aufweist, der dem Querschnitt des Mitnehmerzapfens 10 entspricht, so daß durch Betätigung des Antriebs-Werkzeuges 2 der Knebel 6 innerhalb des Werkzeuges 1 um seinen Drehpunkt 8 verdreht werden kann. Durch diese Verdrehung wird der Klemmabschnitt 7 an ein zu verschraubendes, rundes Bauteil in Form beispielsweise einer Schraubhülse 5 angepreßt und innerhalb der maulschlüsselartigen Aufnahme 4 festgeklemmt, so daß ein Drehmoment auf die Schraubhülse 5 übertragen werden kann.The toggle 6 is equipped with a square in the illustrated embodiment breakthrough 9 for receiving the entrainment pin 10 of the drive tool 2. It is essential that the opening 9 has a non-circular cross-section which corresponds to the cross section of the driving pin 10, so that the knob 6 can be rotated by the actuation of the drive tool 2 within the tool 1 about its pivot point 8. By this rotation of the clamping portion 7 is pressed against a screwed to round member in the form of, for example, a screw 5 and clamped within the spanner-like receptacle 4, so that a torque can be transmitted to the screw 5.

Je nach Drehrichtung des Werkzeuges 1 erfolgt dabei ein Festziehen oder ein Lösen der Schraubhülse 5, wobei das Werkzeug 1 zum Zwecke des Festziehens oder des Lösens einer Schraubhülse 5 jeweils um 180° gewendet werden muß, wie dies die Figuren 5a bis 5e zeigen, und zwar aufgrund der Tatsache, daß über den exzentrischen Klemmabschnitt 7 ein Drehmoment immer nur in einer Drehrichtung übertragbar ist.Depending on the direction of rotation of the tool 1 takes place while tightening or loosening the screw 5, wherein the tool 1 for the purpose of tightening or loosening a screw 5 must be turned by 180 °, as the FIGS. 5a to 5e show, due to the fact that over the eccentric clamping portion 7, a torque is transferable only in one direction of rotation.

Verbleibt das Werkzeug 1 beispielsweise in der in Figur 4 gezeigten Anwendungsposition, bewirkt ein Verdrehen des Werkzeuges 1 im Uhrzeigersinn ein Festziehen der Schraubhülse 5. Ein Verdrehen des Werkzeuges 1 in dieser Position entgegen dem Uhrzeigersinn führt zu einem Leerhub entsprechend einer Ratschenfunktion. Durch diesen möglichen Leerhub kann das Werkzeug 1 unter Zuhilfenahme des Antriebs-Werkzeuges 2 auch unter beengten Raumverhältnissen in jeweils kleinen Winkelabschnitten oder Winkelsektoren zum Festziehen einer Schraubhülse benutzt werden. Wird das Werkzeug 1 hingegen gegenüber der Anwendungsposition gemäß Figur 4 um 180° gewendet, kann entgegen dem Uhrzeigersinn ein Drehmoment auf die Schraubhülse 5 ausgeübt und diese gelöst werden.Remains the tool 1, for example, in the in FIG. 4 shown application position causes a rotation of the tool 1 clockwise tightening the screw 5. A rotation of the tool 1 in this position counterclockwise results in a Leerhub corresponding to a ratchet function. Through this possible idle stroke, the tool 1 can be used with the aid of the drive tool 2 even in confined spaces in each small angle sections or angle sectors for tightening a screw. If the tool 1, however, compared to the application position according to FIG. 4 turned by 180 °, a torque can be exerted counterclockwise on the threaded sleeve 5 and these are released.

Vorteilhafterweise ist die Aufnahme 4 in ihrem dem Klemmabschnitt 7 des Knebels 6 gegenüber liegenden Bereich mit einer Rillung 11 (siehe Figur 7) einer Verzahnung 12 (siehe Figur 6) oder dergleichen versehen, wodurch in Verbindung mit den über den Klemmabschnitt 7 aufzubringen Klemmkräften ein hohes Drehmoment auf eine Schraubhülse 5 übertragen werden kann. Auch der Klemmabschnitt 7 des Knebels 16 kann mit einer Rillung oder einer Verzahnung 16 versehen werden.Advantageously, the receptacle 4 in its the clamping portion 7 of the toggle 6 opposite region with a groove 11 (see FIG. 7 ) of a toothing 12 (see FIG. 6 ) or the like, whereby a high torque can be transmitted to a threaded sleeve 5 in conjunction with the clamping forces applied via the clamping portion 7. Also, the clamping portion 7 of the knob 16 may be provided with a grooving or a toothing 16.

Wie die Figuren 6 und 7 weiterhin deutlich machen, ist der drehbare Knebel 6 über eine Feder 13 vorgespannt und ständig in Anlagerichtung des Klemmabschnittes 7 an einer Schraubhülse 5 belastet.As the FIGS. 6 and 7 continue to make it clear, the rotatable knob 6 is biased by a spring 13 and constantly loaded in the direction of the clamping portion 7 on a screw 5.

Die Kantenlänge des quadratischen Durchbruches 9 innerhalb des Knebels 6 beträgt vorteilhafterweise ¼ Zoll, so daß ein handelsübliches Antriebs-Werkzeug 2 mit einem entsprechend dimensionierten Vierkant-Mitnehmer 10 Verwendung finden kann.The edge length of the square opening 9 within the knob 6 is advantageously ¼ inch, so that a commercially available drive tool 2 with a suitably dimensioned square driver 10 can be used.

Durch die seitlich offene Ausnehmung 4 kann das erfindungsgemäße Werkzeug bequem seitlich auf zu verschraubende Bauteile wie beispielsweise eine Schraubhülse 5 aufgesetzt werden, selbst dann, wenn diese mit Kabeln 14 verbunden sind, wie in Figur 4 gezeigt.Through the laterally open recess 4, the tool according to the invention can be conveniently placed laterally on components to be screwed, such as a screw 5, even if they are connected to cables 14, as in FIG. 4 shown.

Da sich der Durchbruch 9 des Knebels 6 achsparallel zur Aufnahme 4 und nur in einem geringen Abstand zu dieser Aufnahme 4 befindet, verläuft die Längsachse des Antriebs-Werkzeuges 2 im Anwendungsfall parallel zur Längsachse beispielsweise einer Schraubhülse 5, so daß nur ein geringer seitlicher Freiraum für das Ansetzen und Betätigen des Werkzeuges benötigt wird.Since the opening 9 of the knob 6 is axially parallel to the receptacle 4 and only a small distance to this receptacle 4, the longitudinal axis of the drive tool 2 extends in the application parallel to the longitudinal axis, for example a screw 5, so that only a small lateral clearance for the preparation and operation of the tool is needed.

Das Werkzeug 1 besteht aus formidentischen Außenscheiben 14 sowie einer dazwischen angeordneten Zwischenscheibe 15, wobei diese Bauteile miteinander verschraubt oder vernietet sind. Außerdem ist der schon erwähnte Knebel 6 in dem zwischen den Außenscheiben 14 zur Verfügung stehenden Raum drehbar gelagert.The tool 1 consists of identical outer discs 14 and an intermediate washer 15 arranged between them, these components with each other screwed or riveted. In addition, the already mentioned knob 6 is rotatably mounted in the available space between the outer discs 14 space.

Das Werkzeug 1 besteht somit aus wenigen, preiswert herstellbaren und leicht montierbaren Bauteilen.The tool 1 thus consists of a few, inexpensive to produce and easily assembled components.
