Abstract

The slide bracket (5) has an elastically yielding locking body (13) which protrudes into the eye (6) of the bracket and interacts with the locking profile (10) of the slide rail (2). The locking body is a sprung ball (14) and the locking profile in the rail comprises spaced apart channels which lie on the broad side of the rail. The ball is embedded in the broad side wall of the eye in the bracket and functionally acts upon the slide rail independently of the clamping of the slide bracket.

Description

Die Erfindung betrifft ein Spannwerkzeug gemäß Gattungsbegriff des Anspruchs 1.The invention relates to a clamping tool according to the preamble of claim 1.

Ein derartiges Spannwerkzeug in Form einer Schraubzwinge zeigt die DE 91 14 009 U1. Ein eine Spannfläche ausbildender Festbügel ist dort fest am Ende einer Gleitschiene angeordnet. Auf der Gleitschiene ist ein Gleitbügel verschiebbar. Durch Verkanten kann der Gleitbügel, welcher eine Spannfläche besitzt, gegenüber der Gleitschiene rutschgesichert werden.DE 91 14 009 U1 shows such a clamping tool in the form of a screw clamp. A fixed bracket forming a clamping surface is fixedly arranged there at the end of a slide rail. A slide bracket can be moved on the slide rail. By tilting the slide bracket, which has a clamping surface, can be secured against slipping with respect to the slide rail.

Die US 1,452,753 beschreibt ebenfalls eine Schraubzwinge mit Festbügel, daran befestigter Gleitschiene und auf der Gleitschiene gleitenden Gleitbügel. Im Auge des Gleitbügels befinden sich Sperrkugeln, die in der nicht verklemmten Stellung ein Verrutschen des Gleitbügels gegenüber der Gleitschiene verhindern sollen und welche beim Verklemmen der Schraubzwinge zufolge eines Kippens des Gleitbügels gegenüber der Gleitschiene in eine Rastaussparung der Schmalseite der Gleitschiene hineingepreßt werden.The US 1,452,753 also describes a screw clamp with a fixed bracket, a slide rail attached to it and a slide bracket sliding on the slide rail. In the eye of the slide bracket there are locking balls which, in the non-locked position, are intended to prevent the slide bracket from slipping relative to the slide rail and which, when the screw clamp is jammed, are pressed into a recess in the narrow side of the slide rail due to the slide bracket tipping over the slide rail.

Ausgehend vom eingangs genannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, Maßnahmen anzugeben, um ein Verrutschen des Gleitbügels des Spannwerkzeuges in der gelösten Stellung, das heißt bei nicht eingespannten Werkstück auf der Gleitschiene zu verhindern.Starting from the prior art mentioned at the outset, the object of the invention is to provide measures to prevent the sliding bracket of the clamping tool from slipping in the released position, that is to say when the workpiece is not clamped on the slide rail.

Gelöst wird die Aufgabe durch die im Anspruch 1 angegebene Erfindung. Die Unteransprüche stellen vorteilhafte Weiterbildungen der Erfindung dar.The object is achieved by the invention specified in claim 1. The subclaims represent advantageous developments of the invention.

Erfindungsgemäß ist dem Gleitbügel ein Rastkörper zugeordnet, der elastisch ausweichbar ist und in das Auge ragt. Der elastisch ausweichbare Rastkörper wirkt unabhängig von der Verkantung des Gleitbügels auf die Gleitschiene mit einer Rastprofilierung der Gleitschiene zusammen. Der Rastkörper wirkt derart mit der Rastprofilierung der Gleitschiene zusammen, dass die Rutschsicherung bereits vor einem Einspannen eines Werkstückes sicher wirkt. So kann bei einem Ansetzen des Spannwerkzeuges mit einer voreingestellten Lage des Gleitbügels dieser beispielsweise aufgrund von Erschütterung seine gesicherte Stellung nicht verlieren bzw. wieder abrutschen. Durch die Anordnung eines elastisch ausweichbaren Rastkörpers in dem Auge des Gleitbügels ist eine schwerkraftunabhängige Rutschsicherung gegeben. Hierzu ist der Rastkörper derart angeordnet, dass dieser stets elastisch in Richtung auf die Rastprofilierung der Gleitschiene beaufschlagt wird. Die Rutschsicherung ist nur willensbeton aufhebbar. Der Rastkörper ist eine abgefederte Kugel. Durch die Feder wird die Kugel stets in Richtung auf die Rastprofilierung beaufschlagt, was eine sichere Festlegung des Gleitbügels an der Gleitschiene in jeder Raststellung gewährleistet. Die Rastprofilierungen sind in Schienenerstreckungsrichtung beabstandet zueinander liegende Rastmulden. Letztere sind bevorzugt querschnittsangepaßt der Kugel. Es ist eine Vielzahl von Rastmulden vorhanden, wobei der Abstand zwischen zwei Rastmulden bevorzugt im Millimeterbereich, bspw. 3 bis 5 mm, liegt. Hierdurch ist eine Feinjustage zur Vorpositionierung des Gleitbügels gegeben. Die Rastmulden liegen auf der Schienenbreitseite. Es besteht auch die Möglichkeit, die Rastmulden auf beiden Schienenbreitseiten auszubilden zur Zusammenwirkung mit zwei in das Auge des Gleitbügels ragenden Rastkörpern. Vorteilhafterweise ist die Ausbildung so gewählt, dass der Rastkörper etwa in der Mitte der Breitseitenwandung des Auges eingelassen ist. Hierdurch bedingt wirkt der Rastkörper, bspw. in Form einer abgefederten Kugel, mittig auf die, die Rastprofilierung aufweisende Gleitschiene. Wesentlich ist, dass der Rastkörper funktionell unabhängig von der Verklemmung des Gleitbügels auf die Gleitschiene wirkt.According to the invention, a locking body is assigned to the slide bracket, which can be elastically deflected and protrudes into the eye. The elastically evasive locking body works independently of the tilting of the slide bracket on the slide rail with a locking profile of the slide rail. The latching body interacts with the latching profiling of the slide rail in such a way that the anti-slip device already acts securely before a workpiece is clamped. For example, if the tensioning tool is attached to a preset position of the sliding bracket, this cannot lose its secure position or slip again, for example due to vibration. The arrangement of an elastically evasible locking body in the eye of the slide bracket provides a non-gravity anti-slip device. For this purpose, the locking body is arranged in such a way that it is always elastically loaded in the direction of the locking profile of the slide rail. The anti-slip device can only be lifted in concrete. The locking body is a sprung ball. The spring always urges the ball in the direction of the locking profile, which ensures that the slide bracket is securely attached to the slide rail in every locking position. The locking profiles are spaced apart from each other in the rail extension direction. The latter are preferably adapted to the cross section of the ball. There are a large number of locking troughs, the distance between two locking troughs preferably being in the millimeter range, for example 3 to 5 mm. This provides a fine adjustment for pre-positioning the slide bracket. The notches are on the broad side of the rail. There is also the possibility of designing the locking troughs on both broad sides of the rail for interaction with two locking bodies protruding into the eye of the sliding bracket. The design is advantageously selected such that the latching body is embedded approximately in the middle of the broad side wall of the eye. As a result, the locking body, for example in the form of a spring-loaded ball, acts centrally on the slide rail having the locking profile. It is essential that the locking body acts functionally independent of the jamming of the slide bracket on the slide rail.

Nachstehend ist die Erfindung anhand der beigefügten Zeichnung, welche jedoch lediglich zwei Ausführungsbeispiele darstellt, näher erläutert. Es zeigt:

The invention is explained in more detail below with reference to the accompanying drawing, which, however, only shows two exemplary embodiments. It shows:
Fig. 1
an inventive clamping tool in the form of a screw clamp in a side view, relating to a first embodiment, consisting of a steel slide rail with a fixed bracket attached to this and a sliding bracket movable on the slide rail;

an illustration corresponding to FIG. 1, but relating to a second embodiment, the clamping tool being designed as an all-steel screw clamp.

Dargestellt und beschrieben ist zunächst mit Bezug zu Fig. 1 eine Schraubzwinge 1, bestehend aus einer Stahl-Gleitschiene 2 mit einem fest mit diesem verbundenen, bspw. aus Temperguß hergestelltem Festbügel 3. Der Festbügel 3 ist einerends mit der Gleitschiene 2 fest verbunden und bildet anderenends unterseitig eine Spannfläche 4 aus.Shown and described is first with reference to FIG. 1, a screw clamp 1, consisting of a steel slide rail 2 with a fixed bracket 3, for example made of malleable cast iron. The fixed bracket 3 is firmly connected at one end to the slide rail 2 and forms at the other end a clamping surface 4 on the underside.

Auf der Gleitschiene 2 ist weiter ein Gleitbügel 5 verschiebbar angeordnet, wobei die Gleitschiene 2 den Gleitbügel 5 im Bereich seines Auges 6 durchtritt. Im Bereich seines frei auskragenden Endes trägt der Gleitbügel 5 ein, mit einem Gewinde, bspw. einem Trapezgewinde, versehenes Spannorgan 7. Letzteres ist an seinem der Spannfläche 4 des Festbügels 3 zugewandten Ende mit einer Gegenspannfläche 8 und andernendig mit einem Drehgriff 9 zur axialen Verlagerung des Spannorganes 7 versehen.A slide bracket 5 is also slidably arranged on the slide rail 2, the slide rail 2 passing through the slide bracket 5 in the region of its eye 6. In the area of its freely projecting end, the slide bracket 5 carries a tensioning element 7, which is provided with a thread, for example a trapezoidal thread Provide rotary handle 9 for the axial displacement of the clamping element 7.

Vermittels des Spannorganes 7 ist zum Einspannen eines Werkstückes die Gegenspannfläche 8 in Richtung auf die Spannfläche 4 verspannbar.By means of the clamping element 7, the counter clamping surface 8 can be clamped in the direction of the clamping surface 4 for clamping a workpiece.

Die erfindungsgemäße Schraubzwinge 1 ist mit einer Rutschsicherung des Gleitbügels 5 gegenüber der Gleitschiene 2 versehen. Hierzu ist die Gleitschiene 2 mit einer Rastprofilierung 10 versehen, welche im gezeigten Ausführungsbeispiel in Form von, in Schienenerstreckungsrichtung gleichmäßig beabstandet zueinander liegenden Rastmulden 11 ausgebildet ist. Letztere sind mittig auf der Schienenbreitseite 12 angeordnet und wirken mit einem Rastkörper 13 des Gleitbügels 5 zusammen.The screw clamp 1 according to the invention is provided with an anti-slip device for the slide bracket 5 relative to the slide rail 2. For this purpose, the slide rail 2 is provided with a latching profile 10, which in the exemplary embodiment shown is in the form of latching troughs 11 which are evenly spaced apart from one another in the direction of the rail extension. The latter are arranged centrally on the broad side 12 of the rail and cooperate with a locking body 13 of the slide bracket 5.

Dieser Rastkörper 13 ist in dem gezeigten Ausführungsbeispiel eine abgefederte Kugel 14, welche etwa in der Mitte einer Breitseitenwandung 15 des Auges 6 in einer Durchgangsbohrung 16 des Gleitbügels 5 eingelassen ist. Um diese Kugel 14 gegen Herausfallen zu sichern, ist der auf das Auge 6 weisende Endbereich der Bohrung 16 verstemmt derart, daß ein Teilabschnitt der Kugel 14 aus der Bohrung 16 in den Bereich des Auges 6 treten kann.In the exemplary embodiment shown, this latching body 13 is a spring-loaded ball 14, which is embedded approximately in the middle of a broad side wall 15 of the eye 6 in a through hole 16 of the slide bracket 5. In order to secure this ball 14 against falling out, the end region of the bore 16 pointing towards the eye 6 is caulked such that a partial section of the ball 14 can emerge from the bore 16 into the region of the eye 6.

Um den Rastkörper 13 bzw. die Kugel 14 elastisch ausweichbar zu gestalten, ist in der Bohrung 16 eine Druckfeder 17 angeordnet, welche sich einerends gegen die Kugel 14 und anderenends gegen eine, bspw. eingestemmte Schulter der Bohrung 16 abstützt. Die den Rastkörper 13 bildende Kugel 14 ist demnach nach innen, d. h. in Richtung auf die Bohrung 16 elastisch ausweichbar und zugleich durch die Verstemmung gegen Herausfallen gesichert.In order to make the latching body 13 or the ball 14 elastically evasive, a compression spring 17 is arranged in the bore 16, which is supported at one end against the ball 14 and at the other end against a, for example, caulked shoulder of the bore 16. The ball 14 forming the latching body 13 can accordingly be deflected inwards, ie in the direction of the bore 16, and at the same time secured against falling out by the caulking.

Die, die Rastprofilierung 10 bildenden Rastmulden 11 sind in Schienenerstreckungsrichtung gleichmäßig zueinander beabstandet, wobei ein Abstand zwischen zwei Rastmulden 11 im Millimeterbereich, bspw. 3 bis 5 mm, liegt. Der Querschnitt einer jeden Rastmulde 11 ist bevorzugt dem der Kugel 14 angepaßt.The locking troughs 11 forming the locking profile 10 are evenly spaced from one another in the direction of the rail extension, a distance between two locking troughs 11 being in the millimeter range, for example 3 to 5 mm. The cross section of each recess 11 is preferably adapted to that of the ball 14.

Durch die, im wesentlichen aus Rastkörper 13 und Rastprofilierung 10 bestehende Rutschsicherung ist eine Festlegung des Gleitbügels 5 auf der Gleitschiene 2 unabhängig von der Lage des Spannwerkzeuges sichergestellt. Diese voreingestellte Lage des Gleitbügels 5 ist nur willensbetont veränderbar, indem der Gleitbügel 5 entlang der Gleitschiene 2 von Hand verlagert wird. Hierbei kann der Rastkörper 13 bzw. die Kugel 14 ausweichen und findet stets federunterstützt die nächste Raststufe.The anti-slip device, consisting essentially of locking body 13 and locking profile 10, ensures that the sliding bracket 5 is fixed on the sliding rail 2 regardless of the position of the clamping tool. This preset position of the slide bracket 5 can only be changed in a way that is emphasized by shifting the slide bracket 5 by hand along the slide rail 2. Here, the detent body 13 or the ball 14 can dodge and always finds the next detent step spring-assisted.

Diese Rutschsicherung ist nicht, wie aus dem Stand der Technik bekannt, durch Erschütterungen oder unvorsichtige Handhabung aufhebbar. So kann die erfindungsgemäße Schraubzwinge 1 in der voreingestellten Lage des Gleitbügels 5 sicher an das einzuspannende Werkstück herangeführt werden, ohne daß sich die voreingestellte Spannweite zwischen Gleitbügel 5 und Festbügel 3 verändert.As is known from the prior art, this anti-slip device cannot be canceled by vibrations or careless handling. Thus, the screw clamp 1 according to the invention can be securely brought into the workpiece to be clamped in the preset position of the slide bracket 5 without the preset span between the slide bracket 5 and the fixed bracket 3 changing.

In Fig. 4 ist die erfindungsgemäße Rutschsicherung an einer Ganzstahl-Schraubzwinge 1 ausgebildet, wobei Gleitschiene 2 und Festbügel 3 einstückig, bspw. aus einem gezogenen Blankstahl hergestellt sind. Auch hier weist die Gleitschiene 2, eine Rastprofilierung 10 ausbildende Rastmulden 11 auf, welche mit einem in Form einer Kugel 14 ausgebildeten Rastkörper 13 des Gleitbügels 5 zur Bildung der Rutschsicherung zusammenwirken.4, the anti-slip device according to the invention is formed on an all-steel screw clamp 1, the slide rail 2 and the fixed bracket 3 being made in one piece, for example from a drawn bright steel. Here, too, the slide rail 2 has locking troughs 11 which form a locking profile 10 and which are in the form of a recess a ball 14 formed locking body 13 of the slide bracket 5 cooperate to form the anti-slip.
