Description

Die Erfindung betrifft ein Spannwerkzeug, insbesondere eine Schraubzwinge mit einem Festbügel, ausbildend eine Spannfläche und fest verbunden mit einer Gleitschiene, auf welcher ein Gleitbügel verschiebbar und festklemmbar sitzt, mit einer Gegenspannfläche, welche mittels eines Spannorgans gegen ein zwischen Spannfläche und Gegenspannfläche einspannbares Werkstück verspannbar ist, wobei das Auge des Gleitbügels gegenüber einer profilierten Gleitschiene rutschgesichert ist.The invention relates to a clamping tool, in particular a screw clamp with a fixed bracket, forming one Clamping surface and firmly connected with a slide rail, on which a slide bracket can be moved and clamped sits, with a counter clamping surface, which by means of of a clamping element against a between clamping surface and Counter-clamping surface clampable workpiece is, the eye of the slide bracket opposite one profiled slide rail is non-slip.

Derartige Spannwerkzeuge, insbesondere Schraubzwingen, sind in unterschiedlichen Ausführungen, bspw. in Form von sogenannten Ganzstahl-Schraubzwingen oder Schraubzwingen mit einer Profilstahl-Gleitschiene und Temperguß-Bügeln, bekannt. Unter diesen Ausführungsformen sind weiter solche bekannt, welche eine Rutschsicherung des Gleitbügels gegenüber der Gleitschiene aufweisen. Hierzu verkantet der Gleitbügel beim Spannen eines Werkstückes gegenüber dem Festbügel, wodurch der Gleitbügel festgelegt ist. Diesbezüglich ist weiter bekannt, die Gleitschiene zu profilieren. Eine weitere Ausführungsform der Rutschsicherung ist aus der DE-A1 32 18 486 bekannt. Hier ist zur Rutschsicherung des Gleitbügels ein Gewindestift vorgesehen, welcher derart positioniert ist, daß dieser geringfügig in das Auge des Gleitbügels hineinragt. Verkantet der Gleitbügel beim Spannen eines Werkstückes gegenüber der Gleitschiene, so wird das Gewindeprofil des Gewindestiftes gegen die äußere Schmalseite der Gleitschiene gepreßt zur Verhinderung eines Abrutschens des Gleitbügels unter dem Einfluß der Spannkräfte. Clamping tools of this type, in particular screw clamps, are in different versions, for example in shape of so-called all-steel screw clamps or screw clamps with a profiled steel slide rail and malleable iron brackets, known. Among these embodiments are further known those which have a slip protection of the slide bracket relative to the slide rail. For this purpose, the slide bracket tilts when clamping one Workpiece relative to the fixed bracket, creating the slide bracket is set. In this regard, it is also known to profile the slide rail. Another Embodiment of the anti-slip device is from the DE-A1 32 18 486 known. Here is to prevent slipping of the sliding bracket a threaded pin is provided, which is positioned so that it is slightly in the Eye of the sliding bracket protrudes. Tilt the slide bracket when clamping a workpiece in relation to the slide rail, so the thread profile of the grub screw pressed against the outer narrow side of the slide rail to prevent the slide bracket from slipping under the influence of the tension forces.

Im Hinblick auf den zuvor beschriebenen Stand der Technik wird eine technische Problematik der Erfindung darin gesehen, ein Spannwerkzeug der in Rede stehenden Art mit einer von der Lage des Spannwerkzeuges unabhängigen Rutschsicherung anzugeben.In view of the prior art described above becomes a technical problem of the invention seen in it a clamping tool of the one in question Kind with an independent of the position of the clamping tool Specify slip protection.

Diese Problematik ist zunächst und im wesentlichen beim Gegenstand des Anspruches 1 gelöst. Hierbei ist durch einen, dem Gleitbügel zugeordneten, in das Auge ragenden, elastisch ausweichbaren Rastkörper zum Zusammenwirken mit einer Rastprofilierung der Gleitschiene eine von der Lage des Spannwerkzeuges unabhängige Rutschsicherung gegeben. Der Rastkörper wirkt derart mit der Rastprofilierung der Gleitschiene zusammen, daß die Rutschsicherung bereits vor einem Einspannen eines Werkstückes sicher wirkt. Die bekannten Lösungen der Rutschsicherungen wirken teilweise auch im nicht verspannten Zustand, so daß hierdurch eine Vorspannstellung gegeben ist. Diese Rutschsicherungen sind jedoch in dieser Lage des Spannwerkzeuges schwerkraftabhängig. So kann bei einem Ansetzen des Spannwerkzeuges mit einer voreingestellten Lage des Gleitbügels dieser bspw. aufgrund von Erschütterungen seine gesicherte Stellung verlieren und wieder abrutschen. Bei Erschütterungen oder unvorsichtigem Ansetzen des Spannwerkzeuges wird die verkantete Stellung des Gleitbügels zur Gleitschiene aufgehoben, was ein Abrutschen zur Folge hat. Diesem insbesondere handhabungstechnischen Nachteil ist durch die angegebene Erfindung entgegengewirkt. 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. Diese Rutschsicherung ist nur willensbetont aufhebbar. In einer bevorzugten Ausgestaltung ist vorgesehen, daß der Rastkörper eine abgefederte Kugel ist. Durch die Feder wird der in Form einer Kugel ausgebildete Rastkörper stets in Richtung auf die Rastprofilierung beaufschlagt, was eine sichere Festlegung des Gleitbügels an der Gleitschiene in jeder Raststellung gewährleistet. In einer Weiterbildung des Erfindungsgegenstandes ist vorgesehen, daß die Rastprofilierung in Schienenerstreckungsrichtung beabstandet zueinander liegende Rastmulden sind. Letztere sind bevorzugt querschnittsangepaßt dem Rastkörper bzw. der den Rastkörper bildenden Kugel. Es wird weiter bevorzugt, eine Vielzahl von Rastmulden auszubilden, wobei der Abstand zwischen zwei Rastmulden bevorzugt im Millimeterbereich, bspw. 3 bis 5 mm, liegt. Hierdurch ist eine Feinjustage zur Vorpositionierung des Gleitbügels gegeben. Weiter wird bevorzugt, daß die Rastmulden auf der Schienenbreitseite liegen. Es ist jedoch auch denkbar, die Rastmulden schienenschmalseitig anzuordnen. Auch besteht die Möglichkeit, die Rastmulden auf beiden Schienenbreitseiten bzw. Schienenschmalseiten 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. Schließlich ist vorgesehen, daß der Rastkörper funktionell unabhängig von der Verklemmung des Gleitbügels auf die Gleitschiene wirkt.This problem is first and foremost with Subject matter of claim 1 solved. Here is by a protruding into the eye assigned to the slide bracket elastically evasive locking body for interaction with a locking profile of the slide rail slip protection independent of the position of the clamping tool given. The locking body acts with the Snap profiling of the slide rail together that the Anti-slip protection even before one is clamped Workpiece works safely. The known solutions of Anti-slip devices sometimes work even when not under tension Condition, so that this results in a preload position given is. However, these anti-slip devices are in this position of the clamping tool depending on gravity. So when attaching the clamping tool with a preset position of the slide bracket this For example, due to vibrations, its secured Lose position and slip again. With vibrations or careless attachment of the clamping tool the tilted position of the slide bracket becomes The slide rail is lifted, which results in slipping Has. This particular disadvantage in terms of handling is counteracted by the specified invention. By arranging an elastically evasible Locking body in the eye of the slide bracket is one gravity-independent slip protection. For this the locking body is arranged such that it always elastic towards the locking profile of the Slide rail is applied. This anti-slip device can only be canceled with emphasis on the will. In a preferred one Design is provided that the locking body is a sprung ball. The spring is the in Form a spherical locking body always in the direction applied to the locking profile, what a secure fixing of the slide bracket on the slide rail guaranteed in every rest position. In a training course the subject of the invention is provided that the locking profile in the direction of rail extension are spaced-apart locking troughs. Latter are preferably adapted to the cross-section of the locking body or the ball forming the locking body. It will continue preferred to form a plurality of locking troughs, the distance between two locking troughs being preferred is in the millimeter range, for example 3 to 5 mm. This is a fine adjustment for pre-positioning given the slide bracket. It is further preferred that the recesses are on the broad side of the rail. It however, it is also conceivable that the recessed recesses on the narrow side of the rail to arrange. There is also the possibility of Locking troughs on both broad rail sides or narrow rail sides to train to work with two locking bodies protruding into the eye of the sliding bracket. The training is advantageously chosen so that the locking body approximately in the middle of the broad side wall of the eye. This causes the Locking body, for example in the form of a sprung ball, in the middle of the slide rail with the locking profile. Finally, it is provided that the locking body functionally independent of the jamming of the Slide bracket acts on the slide rail.

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.Is shown and described initially with reference to Fig. 1 is a screw clamp 1, consisting of a steel slide rail 2 with one firmly connected to it, For example. Fixed bracket made of malleable cast iron 3. The Fixed bracket 3 is fixed at one end to the slide rail 2 connected and forms a clamping surface on the underside 4 out.

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 Genspennfläche 8 und andernendig mit einem Drehgriff 9 zur axialen Verlagerung des Spannorganes 7 versehen.On the slide rail 2 there is also a slide bracket 5 slidably arranged, the slide rail 2 the Slide bracket 5 passes in the area of his eye 6. in the The slide bracket carries the area of its freely projecting end 5 a, with a thread, for example a trapezoidal thread, provided tensioning element 7. The latter is on his the clamping surface 4 of the fixed bracket 3 facing end a gene separation area 8 and at the other end with a Twist grip 9 for the axial displacement of the clamping element 7 Mistake.

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

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 has a The slide bracket 5 is secured against slipping in relation to the slide rail 2 provided. The slide rail 2 is for this purpose provided a locking profile 10, which in shown embodiment in the form of, in the rail extension direction evenly spaced from each other lying recesses 11 is formed. The latter are arranged in the center on the broad side of the rail 12 and interact 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.This locking body 13 is in the embodiment shown a sprung ball 14, which is approximately in the Center of a broad side wall 15 of the eye 6 in one Through hole 16 of the slide bracket 5 is inserted is. In order to secure this ball 14 against falling out, is the end region of the bore pointing towards the eye 6 16 caulked such that a portion of the ball 14th step out of the bore 16 into the area of the eye 6 can.

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.Around the locking body 13 or the ball 14 elastically evasive to design, is a compression spring in the bore 16 17 arranged, which one end against the Ball 14 and at the other end against, for example, caulked Shoulder of the bore 16 supports. The locking body 13 forming ball 14 is therefore inwards, i. H. in Direction towards the bore 16 and elastically evasive 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 equal to each other in the direction of rail extension spaced apart, a distance between two Notches 11 in the millimeter range, for example 3 to 5 mm, lies. 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.By, essentially consisting of locking body 13 and locking profile 10 existing slip protection is one Fixing the slide bracket 5 on the slide rail 2 ensured regardless of the position of the clamping tool. This preset position of the slide bracket 5 can only be changed by the slide bracket 5 is shifted by hand along the slide rail 2. Here, the locking body 13 or the ball 14 can dodge and always finds the next one with spring support Rest step.

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.This anti-slip device is not like the state of the art Technique known, from shocks or careless Handling can be canceled. So the invention Screw clamp 1 in the preset position of the slide bracket 5 safely guided to the workpiece to be clamped without changing the preset span changed between slide bracket 5 and fixed bracket 3.

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 zusammenwirken4 the anti-slip device according to the invention is on an all-steel screw clamp 1, wherein Slide rail 2 and fixed bracket 3 in one piece, for example a drawn bright steel are made. Here too the slide rail 2 has a locking profile 10 training locking troughs 11, which with a shape a ball 14 formed locking body 13 of the slide bracket 5 cooperate to form the anti-slip device
