Description

Die Erfindung betrifft eine Spannvorrichtung, insbesondere Schraubstock, mit zum Spannen eines Werkzeugs oder Werkstücks relativ zueinander verfahrbaren Halteorganen, an denen je eine Spannbacke lösbar angebracht ist.The invention relates to a clamping device, in particular vice, with Clamping a tool or workpiece can be moved relative to each other Holding elements, on each of which a jaw is detachably attached.

Eine solche Spannvorrichtung wird heute allgemein zum Spannen von Werkzeugen oder Werkstücken verwendet und ist beispielsweise in der DE 197 56 695 A1 gezeigt. Bei diesen Spannvorrichtungen wird eine der Spannbacken an einem in einem Schlittenbett verfahrbaren Schlitten befestigt, während die andere Spannbacke als feste Spannbacke ausgebildet und an einem festen Halteorgan angebracht ist. Lediglich bei Spannvorrichtungen zum zentrischen Spannen sind beide Spannbacken an einem verfahrbaren Schlitten befestigt.Such a clamping device is now generally used for clamping tools or workpieces and is used for example in DE 197 56 695 A1 shown. With these clamping devices, one of the clamping jaws is attached to an in one sled bed attached to the sled while the other Clamping jaw designed as a fixed clamping jaw and on a fixed holding member is appropriate. Only for clamping devices for central clamping are both jaws attached to a movable carriage.

Die Spannbacken werden an dem Halteorgan, also an dem festen Halteorgan oder dem Schlitten, angeschraubt. Diese Art der Befestigung ist aufwendig. Zum Auswechseln einer Spannbacke ist stets ein Werkzeug erforderlich. The clamping jaws are on the holding member, that is, on the fixed holding member or the sled, screwed on. This type of attachment is complex. To the A tool is always required to replace a clamping jaw.

Hiervon ausgehend liegt der Erfindung das Problem zugrunde, eine Spannvorrichtung, insbesondere einen Schraubstock, zu schaffen, bei dem sich die Spannbacken einfach und damit schnell auswechseln lassen.Proceeding from this, the invention is based on the problem of a Clamping device, in particular to create a vice, in which the Have the jaws replaced quickly and easily.

Zur Lösung dieses Problems ist das erfindungsgemäße Spannwerkzeug dadurch gekennzeichnet, daß wenigstens eine der Spannbacken mittels einer Schwalbenschwanzverbindung mit keilförmig zueinander verlaufenden Seitenwangen an dem Halteorgan angebracht ist.The clamping tool according to the invention is thereby to solve this problem characterized in that at least one of the jaws by means of a Dovetail connection with wedge-shaped to each other Sidewalls is attached to the holding member.

Aufgrund der Schwalbenschwanzverbindung braucht die Spannbacke lediglich in das zugehörige Halteorgan eingeschoben werden. Es ergibt sich aufgrund des keilförmigen Verlaufs der Seitenwangen der Schwalbenschwanzverbindung, insbesondere wenn der Keilwinkel selbsthemmend ausgebildet ist, eine Klemmwirkung zwischen Halteorgan und Spannbacke, durch welche die Spannbacke sicher fixiert ist. Die Spannbacke läßt sich durch einen einfachen Hammerschlag oder dergleichen leicht und schnell wieder lösen.Due to the dovetail connection, the clamping jaw only needs in the associated holding member can be inserted. It results from the wedge-shaped course of the side cheeks of the dovetail connection, especially if the wedge angle is self-locking, a Clamping effect between the holding member and the clamping jaw, through which the Jaw is securely fixed. The jaw can be easily Loosen hammer blow or the like quickly and easily.

Vorzugsweise ist die Schwalbenschwanzverbindung quer zur Spannrichtung der Spannbacken ausgebildet. Hierdurch wird ein selbsttätiges Lösen der Spannbacke, beispielsweise infolge des Spannen eines Werkstückes, vermieden.The dovetail connection is preferably transverse to the tensioning direction Jaws formed. This will automatically release the clamping jaw, avoided, for example, due to the clamping of a workpiece.

Selbstverständlich empfiehlt es sich, beide Spannbacken mit der Schwalbenschwanzverbindung zu versehen, so daß beide Spannbacken auf einfache Weise ausgewechselt werden können. In diesem Fall sollten die Einschubrichtungen, und damit auch die Ausschubrichtungen, der Spannbacken zueinander gegenläufig ausgebildet sein. Hierdurch wird vermieden, daß sich die Spannbacken während der Bearbeitung eines Werkstückes infolge von Querkräften selbsttätig lösen.Of course it is recommended to use both jaws with the To provide dovetail connection so that both jaws on can be replaced easily. In this case, the Directions of insertion, and thus also the directions of extension, of the jaws be designed in opposite directions to each other. This avoids that the Clamping jaws during the machining of a workpiece due to transverse forces solve automatically.

Beim Einsatz von Spannwerkzeugen in Bearbeitungszentren, bei denen ein Werkstück fest in die Spannvorrichtung eingespannt und dann zusammen mit der Spannvorrichtung von Bearbeitungsstation zu Bearbeitungsstation weitergegeben wird, kommt es auf eine definierte Anlage des Werkstückes im Spannwerkzeug an, damit es in den jeweiligen Bearbeitungsstationen definiert positioniert ist. Dieses wird nach einer Weiterbildung der Erfindung dadurch sichergestellt, daß die in Spannrichtung der Spannbacke gesehen äußere Seitenwange der Schwalbenschwanzverbindung senkrecht zur Spannrichtung verläuft. Hierdurch werden auch Querkräfte auf die Schwalbenschwanzverbindung aufgrund der Spannkräfte vermieden, da die Spannkräfte senkrecht zur äußeren Seitenwand gerichtet sind. Vorzugsweise wird diese Schwalbenschwanzverbindung mit der senkrecht zur Spannrichtung verlaufenden Seitenwange der festen Spannbacke zugeordnet.When using clamping tools in machining centers where a Workpiece firmly clamped in the clamping device and then together with the Clamping device passed from processing station to processing station it depends on a defined system of the workpiece in the clamping tool, so that it is positioned in a defined manner in the respective processing stations. This is ensured according to a development of the invention that the in Clamping direction of the jaw seen outer side of the Dovetail connection runs perpendicular to the clamping direction. hereby are also shear forces on the dovetail joint due to the Clamping forces avoided because the clamping forces are perpendicular to the outer side wall are directed. This dovetail connection is preferably connected to the Side cheek of the fixed jaw running perpendicular to the clamping direction assigned.

Nach einer konstruktiven Ausgestaltung der Erfindung ist für die Schwalbenschwanzverbindung der Schwalbenschwanz der Spannbacke und eine korrespondierende Schwalbenschwanznut dem Halteorgan zugeordnet. Das Halteorgan kann mit einer Nachgiebigkeit ausgebildet sein, die vorzugsweise unterhalb der Schwalbenschwanznut angeordnet ist. Durch diese Nachgiebigkeit wird die Klemmsicherheit der Verbindung erhöht. Die Nachgiebigkeit läßt sich auf einfache Weise durch eine Materialreduzierung im Halteorgan realisieren.According to a constructive embodiment of the invention for Dovetail joint the dovetail of the jaw and one corresponding dovetail groove assigned to the holding member. The Retaining member can be designed with a resilience, which is preferably is arranged below the dovetail groove. Because of this compliance the safety of the connection is increased. The flexibility can be relied on easily realized by reducing the material in the holding member.

Nach einer Weiterbildung der Erfindung sind an der Kontaktfläche zwischen Spannbacke und dem zugehörigen Halteorgan eine oder mehrere Freimachungen angeordnet, die durch definierte Auflageflächen und Freiräume eine elastische Verformung der Schwalbenschwanzverbindung ermöglichen, welche ihrerseits das Nachgreifen der Verbindung fördern. Die Freimachung ist insbesondere als quer zur Spannrichtung verlaufende, flache Nut ausgebildet. Sie kann in Spannrichtung gesehen hinter und/oder vor der Schwalbenschwanznut und/oder im Bereich der Schwalbenschwanznut angeordnet sein. Dabei ist die vor und/oder hinter der Schwalbenschwanznut angeordnete Freimachung vorzugsweise in der Spannbacke und die im Bereich der Schwalbenschwanznut angeordnete Freimachung im Halteorgan angeordnet.According to a development of the invention, at the contact surface between Clamping jaw and the associated holding element one or more frankings arranged, the elastic by defined contact surfaces and free spaces Allow deformation of the dovetail connection, which in turn the Encourage understanding of the connection. The franking is in particular as transverse to Flat groove running in the clamping direction. You can in the direction of tension seen behind and / or in front of the dovetail groove and / or in the area of the Dovetail groove can be arranged. The is in front of and / or behind the Clearance arranged in dovetail groove preferably in the clamping jaw and the franking arranged in the region of the dovetail groove Holding organ arranged.

Die gezeigte Spannvorrichtung weist ein Schlittenbett 10 auf, in dem ein Schlitten 11 längsverschieblich geführt ist. Betätigt wird der Schlitten 11 dabei durch eine Gewindespindel, die in einem stirnseitig am Schlittenbett 10 angeschraubten Deckel 12 gelagert ist und von der in den Fig. 2 und 3 lediglich der Sechskantkopf 13 sichtbar ist. An der Oberseite des Schlittenbettes 10 ist eine Halteplatte 14 befestigt, nämlich angeschraubt. Diese Halteplatte 14 trägt eine Spannbacke 15, die mit einer stufenartig abgesetzten Auflagefläche 16 und einer senkrecht hierzu angeordneten Spannfläche 17 versehen ist. Eine weitere, analog ausgebildete Spannbacke 18, die ebenfalls eine stufenartig abgesetzte Auflagefläche 19 und eine senkrecht hierzu angeordnete Spannfläche 20 aufweist, wird von dem Schlitten 11 getragen.The clamping device shown has a slide bed 10, in which a slide 11 is guided longitudinally. The carriage 11 is actuated by a Threaded spindle, which is screwed into a cover screwed onto the end of the slide bed 10 12 is mounted and of which only the hexagon head 13 in FIGS. 2 and 3 is visible. A holding plate 14 is fastened to the top of the slide bed 10, namely screwed on. This holding plate 14 carries a jaw 15, which with a stepped support surface 16 and a perpendicular to it Clamping surface 17 is provided. Another, analog trained jaw 18, the also a stepped support surface 19 and a perpendicular to it arranged clamping surface 20 is carried by the carriage 11.

Die Art der Befestigung der Spannbacken 15, 18 an der Halteplatte 14 bzw. dem Schlitten 11 ist hier in besonderer Art gelöst. Die Spannbacken 15, 18 weisen jeweils einen Schwalbenschwanz 21, 22 auf, die in korrespondierenden Schwalbenschwanznuten 23, 24 in der Halteplatte 14 bzw. den Schlitten 11 geführt sind. Konkret wird die Spannbacke 15 bzw. 18 von der Seite in die jeweils zugehörige Schwalbenschwanznut 23 bzw. 24 eingeschoben (Einschubrichtung). Die so gebildeten Schwalbenschwanzverbindungen weisen in Einschubrichtung keilförmig zulaufende Seitenwangen 25, 26 bzw. 27, 28 auf. Der Keilwinkel der keilförmig zulaufenden Seitenwangen 25, 26 bzw. 27, 28 ist dabei so gewählt, daß sich eine selbsthemmende Klemmung der Schwalbenschwänze 21, 22 in den zugehörigen Schwalbenschwanznuten 23, 24 ergibt.The type of attachment of the jaws 15, 18 on the holding plate 14 and the Carriage 11 is solved here in a special way. The jaws 15, 18 have each have a dovetail 21, 22, which in corresponding Dovetail grooves 23, 24 in the holding plate 14 and the slide 11 out are. Specifically, the jaw 15 or 18 from the side in each associated dovetail groove 23 or 24 inserted (direction of insertion). The dovetail connections formed in this way point in the direction of insertion wedge-shaped side walls 25, 26 or 27, 28. The wedge angle of the wedge-shaped side walls 25, 26 and 27, 28 is selected so that self-locking clamping of the dovetails 21, 22 in the associated dovetail grooves 23, 24 results.

Wie in den Figuren zu erkennen ist, sind die Schwalbenschwanzverbindungen quer zur Spannrichtung 29 orientiert. Die Schwalbenschwanzverbindungen sind dabei in ihrer Keilform gegenläufig zueinander ausgebildet. Wie besonders gut in Fig. 3 zu erkennen ist, kann also in Spannrichtung 29 gesehen die Spannbacke 18 nach links aus dem Schlitten 11 herausgeschoben werden, während die Spannbacke 15 nach rechts ausschiebbar ist. Ferner ist die Schwalbenschwanzverbindung für die feste Spannbacke 15 so ausgebildet, daß die in Spannrichtung gesehen äußere Seitenwange 26 senkrecht zur Spannrichtung 29 orientiert ist.As can be seen in the figures, the dovetail connections are transverse oriented to the clamping direction 29. The dovetail connections are in their wedge shape in opposite directions. How particularly well in Fig. 3 too can be seen, can be seen in the clamping direction 29, the jaw 18 to the left can be pushed out of the carriage 11 while the jaw 15 after can be pushed out to the right. Furthermore, the dovetail connection is for the fixed Clamping jaw 15 designed so that the outer seen in the clamping direction Sidewall 26 is oriented perpendicular to the clamping direction 29.

In der Halteplatte 14 ist gezielt eine Nachgiebigkeit unterhalb der Schwalbenschwanznut 23 angebracht, nämlich durch eine Materialreduzierung 30. Diese Materialreduzierung 30 ist konkret durch die Ausfräsung für die Schwalbenschwanznut 23 selbst gebildet.In the holding plate 14 is a compliance below the Dovetail groove 23 attached, namely by a material reduction 30. This material reduction 30 is due to the milling for the Dovetail groove 23 formed itself.

Um definierte Auflageflächen für die Spannbacken 15, 18 auf der Halteplatte 14 bzw. dem Schlitten 11 zu schaffen, sind ferner Freimachungen 31, 32, 33 bzw. 34, 35 vorgesehen. Diese Freimachungen 31..35 sind als quer zur Spannrichtung 29 verlaufende Nuten in den Kontaktflächen zwischen den Spannbacken 15, 18 mit der Halteplatte 14 bzw. dem Schlitten 11 gebildet. Die Tiefe dieser Freimachungen 31..35 ist in Fig. 2 zur besseren Verdeutlichung übertrieben dargestellt. Die Freimachung 31 ist an der festen Spannbacke 15 in Spannrichtung 29 gesehen hinter dem Schwalbenschwanz 21 vorgesehen. Die Freimachung 32 ist unterhalb der Schwalbenschwanznut 23 in der Halteplatte 14 vorgesehen und die Freimachung 33 ist in Spannrichtung 29 gesehen vor dem Schwalbenschwanz 21 wiederum in der Spannbacke 15 vorgesehen. Die der verfahrbaren Spannbacke 18 zugeordneten Freimachungen 34 und 35 sind zum einen als Freimachung 34 in dem Schlitten 11 unterhalb der Schwalbenschwanznut 24 vorgesehen und zum anderen als Freimachung 35 in Spannrichtung 29 gesehen hinter dem Schwalbenschwanz 22 in der Spannbacke 18.In order to have defined contact surfaces for the clamping jaws 15, 18 on the holding plate 14 or to create the carriage 11, frankings 31, 32, 33 or 34, 35 provided. These frankings 31..35 are considered to be transverse to the clamping direction 29 running grooves in the contact surfaces between the jaws 15, 18 with the holding plate 14 and the carriage 11 are formed. The depth of these frankings 31..35 is exaggerated in Fig. 2 for clarity. The Postage 31 is seen on the fixed jaw 15 in the clamping direction 29 provided behind the dovetail 21. The franking 32 is below the dovetail groove 23 is provided in the holding plate 14 and the The franking 33 is seen in the tensioning direction 29 in front of the dovetail 21 again provided in the jaw 15. The movable jaw 18 associated frankings 34 and 35 are on the one hand as franking 34 in the carriage 11 provided below the dovetail groove 24 and for other than franking 35 seen in the clamping direction 29 behind the Dovetail 22 in the jaw 18.

Die Seitenwangen 25, 26 sind in der Seitenansicht gemäß Fig. 2 um etwa 45 ° nach außen geneigt, so daß sie die jeweils zugehörige Schwalbenschwanznut 23 bzw. 24 hinterschneiden. Alternativ können die Seitenwangen 25, 26 auch einen anderen Winkel geneigt oder senkrecht ausgerichtet sein, so daß sich keine Hinterschneidung mehr ergibt. The side walls 25, 26 are in the side view according to FIG. 2 by approximately 45 ° inclined on the outside so that they have the associated dovetail groove 23 or 24 undercut. Alternatively, the side walls 25, 26 can also be another Angle inclined or aligned vertically so that there are none Undercut more results.
