Spannelement für Werkstücke, insbesondere SchraubstockClamping element for workpieces, especially vise
Die Erfindung betrifft ein Spannelement für Werkstücke, insbesondere Schraub¬ stock, mit einer ersten Spannbacke und einer zweiten Spannbacke, welche an einem Schlittenbett gelagert sind.The invention relates to a clamping element for workpieces, in particular Schraub¬ stock, with a first clamping jaw and a second clamping jaw, which are mounted on a carriage bed.
Derartige Spannelemente, nämlich Schraubstöcke, sind aus der Praxis bekannt wie folgt. Die bisherigen Schraubstöcke erzeugen auf mechanischem, hydrauli¬ schem oder pneumatischem Weg eine Spannkraft, die über den zu spannenden Gegenstand, also im Allgemeinen ein Werkstück von den als Gegenlager wir¬ kenden Spannbacken aufgenommen wird. Dabei entsteht ein Biegemoment auf ein die Spannbacken führendes Schlittenbett, welches durch die Steifigkeit die- ses Schlittenbettes aufgefangen werden muß. Dieses führt zu elastischen Ver¬ formungen des Schlittenbettes, welche zu Lasten der Bearbeitungsgenauigkei¬ ten gehen. Für hochgenau zu bearbeitende Werkstücke ist es deshalb bei den bekannten Schraubstöcken notwendig, das Schlittenbett immer steifer und damit schwerer zu bauen. Dabei ist auch zu berücksichtigen, daß aufgrund verbesser- ter Werkzeuge heutzutage höhere Bearbeitungsgeschwindigkeiten und damit einhergehende höhere Bearbeitungskräfte auf das Werkstück einwirken, die mit einer Erhöhung der vom Schraubstock auszuübenden Spannkraft aufgefangen werden müssen. Diese erhöhte Spannkraft bedingt wiederum ein größeres Bie¬ gemoment.Such clamping elements, namely vices, are known in practice as follows. The previous vices generate mechanical, hydraulic or pneumatic way a clamping force, which is taken over the object to be clamped, so in general a workpiece from the effective as an abutment jaw ing jaws. This results in a bending moment on a slide bed guiding the clamping jaws, which must be absorbed by the rigidity of this slide bed. This leads to elastic deformations of the carriage bed, which are at the expense of the machining accuracies. For highly accurate workpieces it is therefore necessary in the known vises, the carriage bed getting stiffer and harder to build. It should also be borne in mind that due to improved tools nowadays higher machining speeds and concomitant higher machining forces act on the workpiece, which must be absorbed by increasing the clamping force to be exerted by the vice. This increased clamping force in turn requires a larger Bie¬ moment.
Hiervon ausgehend liegt der Erfindung das Problem zugrunde, ein Spannele¬ ment, insbesondere einen Schraubstock, zu schaffen, bei dem konstruktionsbe¬ dingt ein Biegemoment auf das Schlittenbett vermieden ist.Proceeding from this, the problem underlying the invention is to provide a clamping element, in particular a vice, in which a bending moment on the carriage bed is prevented by design.

Zur Lösung dieses Problems ist das erfindungsgemäße Spannelement dadurch gekennzeichnet, daß die Resultierenden der infolge der auf die Spannbacken einwirkenden Spannkräfte von den Spannbacken in das Schlittenbett eingeleite¬ ten Kräfte in der Ebene der neutralen Faser des Schlittenbettes liegen.To solve this problem, the clamping element according to the invention is characterized in that the resultant of the forces acting on the clamping jaws clamping forces of the jaws in the carriage bed eingelegt¬ th forces in the plane of the neutral fiber of the carriage bed.
Beim Spannen eines Werkstücks ergibt sich ein Kraftkreislauf vom Werkstück über die Spannbacken und das Schlittenbett infolge der Spannkräfte. Erfin¬ dungsgemäß ist nun dafür gesorgt, daß die dabei in das Schlittenbett eingeleite¬ te Kraft in der Ebene der neutralen Faser des Schlittenbettes liegt. Dadurch werden im Schlittenbett nur noch reine Zug- oder Druckkräfte in Längsrichtung des Schlittenbettes wirksam. Ein Biegemoment auf das Schlittenbett tritt nicht mehr auf.When clamping a workpiece results in a power circuit from the workpiece on the jaws and the carriage bed due to the clamping forces. According to the invention, it is now ensured that the force introduced into the carriage bed in this case lies in the plane of the neutral fiber of the carriage bed. As a result, only pure tensile or compressive forces in the longitudinal direction of the carriage bed become effective in the carriage bed. A bending moment on the carriage bed no longer occurs.
Die erfindungsgemäße Krafteinleitung in das Schlittenbett kann nach einer kon- struktiven Ausgestaltung der Erfindung dadurch erreicht werden, daß die erste Spannbacke und/oder zweite Spannbacke mittels jeweils eines Gelenkbolzens an einem Schlittenbett abstützen, wobei Bohrungen für die Gelenkbolzen in ei¬ ner neutralen Faser des Schlittenbettes angeordnet sind. Hierdurch reduziert sich der Hebelarm, mit dem Kräfte infolge der Spannkräfte in das Schlittenbett eingeleitet werden, auf null, so daß ein Biegemoment vollständig vermieden ist. Je nach dem, ob die Spannbacken als einarmige Hebel oder als zweiarmige Hebel ausgebildet sind, ergeben sich nur Druck- bzw. Zugkräfte auf das Schlit¬ tenbett. Dementsprechend übt das Betätigungsorgan Zug- oder Druckkräfte auf die Spannbacken aus.According to a structural embodiment of the invention, the introduction of force into the carriage bed according to the invention can be achieved by supporting the first clamping jaw and / or second clamping jaw on a carriage bed by means of a respective hinge pin, with bores for the hinge pins in a neutral fiber of the carriage bed are arranged. This reduces the lever arm, with the forces are introduced due to the clamping forces in the carriage bed to zero, so that a bending moment is completely avoided. Depending on whether the clamping jaws are designed as a one-armed lever or as a two-armed lever, only pressure or tensile forces on the Schlit¬ tenbett arise. Accordingly, the actuator exerts tensile or compressive forces on the jaws.
Die Spannbacken sind vorzugsweise als zweiarmige Hebel ausgebildet, wobei jeweils dem einen Hebelarm eine Spannfläche zugeordnet ist und der andere Hebelarm auf eine Schubstange einwirkt. Die Spannvorrichtung wird als gleich¬ sam auf eine dem Werkstück gegenüberliegende Seite der neutralen Faser dup- liziert, nur daß hier anstelle des Werkstücks auf die Schubstange eingewirktThe clamping jaws are preferably designed as two-armed lever, wherein in each case one lever arm, a clamping surface is associated and the other lever arm acts on a push rod. The tensioning device is duplexed onto a side of the neutral fiber opposite the workpiece, while acting on the pushrod instead of the workpiece

wird. Sind die Hebelarme jeweils an den Spannbacken gleich lang ergeben sich gleich Kräfte auf die Schubstange und das Werkstück. Bei bekannten Schraub¬ stöcken wirkt aufgrund der Montageart der festen Spannbacke immer auch eine Kraftkomponente senkrecht zur Spannkraft auf das Schlittenbett ein. Dieses ist mit der vorstehend beschriebenen Weiterbildung vermieden. Schon dadurch ergibt sich unabhängig vom Grundgedanken der Erfindung eine erhebliche Re¬ duktion des auf das Schlittenbett einwirkenden Biegemomentes, so daß diese Weiterbildung auch unabhängig vom Grundgedanken vorteilhaft eingesetzt wer¬ den kann.becomes. If the lever arms on the clamping jaws are the same length, forces on the push rod and the workpiece are the same. In known Schraub¬ sticks acts due to the mounting of the fixed jaw always a force component perpendicular to the clamping force on the carriage bed. This is avoided with the development described above. This alone, regardless of the basic idea of the invention, results in a considerable reduction of the bending moment acting on the carriage bed, so that this development can also be used advantageously independently of the basic idea.
Die erfindungsgemäße Konstruktion bietet darüber hinaus noch einen weiteren Vorteil. Aufgrund der Durchbiegung des Schlittenbettes und auch aufgrund der Druckkräfte auf die Spannbacken werden bei bekannten Spannelementen die Spannbacken nach außen „abkippen". Dieses wurde bei den bekannten Spann- elementen durch relativ komplizierte Maßnahmen, sogenannte Niederzugele¬ mente oder Niederzugbacken, kompensiert. Bei dem erfindungsgemäßen Spannelement sind diese Maßnahmen nicht mehr erforderlich, insbesondere wenn die Gelenkbolzen für die Spannbacken so angeordnet sind, daß sich an den Spannflächen eine nach unten gerichtete Bewegungskomponente ergibt.The construction according to the invention also offers a further advantage. Due to the deflection of the carriage bed and also due to the compressive forces on the clamping jaws, the clamping jaws are "tilted outwards" in the case of known clamping elements, which has been compensated in the known clamping elements by relatively complicated measures, so-called low-tensile elements or pull-down jaws Clamping elements, these measures are no longer necessary, especially when the hinge pins are arranged for the clamping jaws so that there is a downward movement component on the clamping surfaces.
Als Betätigungsorgan kann vorzugsweise ein Druckmittelzylinder dienen. Auch eine Kniehebelmechanik, Spindeltriebe oder andere mechanische, hydraulische, pneumatische oder magnetische Lösungen sind denkbar.As actuator can preferably serve a pressure cylinder. Also, a toggle mechanism, spindle drives or other mechanical, hydraulic, pneumatic or magnetic solutions are conceivable.
Die bekannten Schraubstöcke werden zum Teil über eine externe Hydraulikver¬ sorgung direkt mit Druckmittel betätigt. Darüber hinaus werden aber auch Schraubstöcke verwendet, bei denen mittels einer Spindel ein Hydraulikkolben betätigt wird. Der Spannbacke ist dann ein Kolben größeren Durchmessers zu¬ geordnet. Hierdurch wird die durch die Spindel ausgeübte Kraft im Verhältnis der Flächen der beiden Kolben verstärkt und als Spannkraft zur Verfügung ge-The known vices are operated partly via an external Hydraulikver¬ supply directly with pressure medium. In addition, however, vices are used in which by means of a spindle, a hydraulic piston is actuated. The jaw is then assigned a piston of larger diameter zu¬. As a result, the force exerted by the spindle is amplified in the ratio of the areas of the two pistons and is available as a clamping force.

Bei Schraubstöcken mit hydraulischer Kraftverstärkung, aber auch bei direkt hydraulisch angetriebenen Schraubstöcken, ist die zur Verfügung stehende Spannkraft bzw. die Kraftübersetzung durch den Hydraulikdruck und den zur Verfügung stehenden Bauraum für die Kolbenflächen begrenzt.When vices with hydraulic power boost, but also with directly hydraulically driven vices, the available clamping force or force transmission is limited by the hydraulic pressure and the available space for the piston surfaces.
Das erfindungsgemäße Spannelement verfügt zur Vermeidung des vorstehend beschriebenen Nachteils nach einer allerdings auch unabhängig denkbaren Weiterbildung neben einem ersten Druckmittelzylinder der eine der beiden Spannbacken betätigt, über einen weiteren Druckmittelzylinder, der die jeweils andere Spannbacke betätigt.The clamping element according to the invention has to avoid the disadvantage described above for a however also independently conceivable development in addition to a first pressure medium cylinder which actuates one of the two clamping jaws, via a further pressure medium cylinder, which actuates the respective other clamping jaw.
Die zweite Spannbacke verfügt demnach über eine eigene Druckmittelversor¬ gung und entfaltet ihrerseits eine Spannkraft zusätzlich zur Spannkraft der ers¬ ten Spannbacke. Die Gesamtspannkraft ist damit um die durch die zweite Spannbacke zur Verfügung stehenden Spannkraft erhöht.Accordingly, the second clamping jaw has its own pressure medium supply and in turn develops a clamping force in addition to the clamping force of the first clamping jaw. The total clamping force is thus increased by the clamping force available by the second clamping jaw.
Vorzugsweise ist der weitere Druckmittelzylinder mit dem ersten Druckmittelzy¬ linder hydraulisch bzw. pneumatisch gekoppelt. Es braucht so nur eine einzige Druckmittelversorgung vorgesehen zu werden. Darüber hinaus ergibt sich an beiden Druckmittelzylindern der gleiche Druckmitteldruck. So ist es konstruktiv am einfachsten, wenn der weitere Druckmittelzylinder und der erste Druckmittel- Zylinder über eine Bypaßleitung miteinander verbunden sind. Diese Lösung bie¬ tet sich insbesondere auch für Schraubstöcke mit hydraulischer Kraftverstär¬ kung an, bei denen die Spindelkraft in den Druckmitteldruck für den ersten und den weiteren Druckmittelzylinder umgesetzt wird. Wenn dann noch die Kolben¬ flächen des ersten Druckmittelzylinders und des weiteren Druckmittelzylinders identisch sind, ergeben sich für beide Spannbacken gleiche Spannkräfte.The further pressure medium cylinder is preferably hydraulically or pneumatically coupled to the first pressure medium cylinder. It only needs a single pressure medium supply to be provided. In addition, the same pressure medium pressure results at both pressure medium cylinders. So it is the simplest constructive, if the other pressure medium cylinder and the first pressure medium cylinder are connected to each other via a bypass line. This solution is particularly suitable for vices with hydraulic power amplification, in which the spindle force is converted into the pressure medium pressure for the first and the further pressure medium cylinder. If then the piston surfaces of the first pressure medium cylinder and of the further pressure medium cylinder are identical, the same clamping forces result for both clamping jaws.

Fig. 7 ein weiteres Ausführungsbeispiel eines Spannelementes, nämlich einen Schraubstock, mit den Erfindungsmerkmalen im Längsschnitt.Fig. 7 shows another embodiment of a clamping element, namely a vise, with the features of the invention in longitudinal section.
Bei dem in den Figuren 1 bis 5 dargestellten Spannelement handelt es sich um einen Schraubstock 10. Dieser Schraubstock 10 weist ein Schlittenbett 11 und eine „feste" Spannbacke 12 sowie eine verschiebliche Spannbacke 13 auf. Da¬ bei ist die „feste" Spannbacke 12 nur insoweit fest, als daß sie beim Spannen eines Werkstücks nicht direkt über einen größeren Weg bestätigt wird, was aus der nachfolgenden Beschreibung noch weiter deutlich wird.1 to 5 is a vise 10. This vise 10 has a carriage bed 11 and a "fixed" clamping jaw 12 and a displaceable clamping jaw 13. The "fixed" clamping jaw 12 is only there insofar as it is not confirmed when clamping a workpiece directly over a longer way, which will become apparent from the following description.
Bei der Spannbacke 13 handelt es sich um eine Spannbacke mit hydraulischer Kraftverstärkung. Betätigt wird die Spannbacke 13 über eine Spindel 14. Mittels der Spindel 14 wird die Spannbacke 13 solange an das Werkstück herangefah¬ ren, bis sie zur Anlage an den Werkstück kommt. Sodann übt die Spindel 14 nur noch einen Druck auf eine Hydraulikflüssigkeit in einem Hydraulikzylinder 15 aus, die ihrerseits eine weitere Kolbenfläche innerhalb der Spannbacke 13 än¬ dert in an sich bekannter Art beaufschlagt. Die Spannbacke 13 verfügt über eine Anschlußmöglichkeit für eine externe Hydraulikleitung. Dieses ist bereits beim Stand der Technik der Fall, um die vorliegende Spannbacke 13 gegebenenfalls auch an eine externe Hydraulikleitung anschließen zu können. An diesen Hydraulikanschluß ist über eine Hydraulikverschraubung 16 eine Bypaßleitung 17 angeschlossen. Unterhalb der Spannbacke 13 ist ein weiterer Druckmittelzy- linder 18 vorgesehen, welcher über die Bypaßleitung 17, die über eine weitere Hydraulikverschraubung 19 an dem weiteren Druckmittelzylinder 18 angeschos- sen ist, mit Druckmittel beaufschlagt wird.When the jaw 13 is a jaw with hydraulic power boost. The clamping jaw 13 is actuated via a spindle 14 by means of the spindle 14. The clamping jaw 13 is moved on to the workpiece until it comes to bear against the workpiece. Then, the spindle 14 only exerts a pressure on a hydraulic fluid in a hydraulic cylinder 15, which in turn acts on a further piston surface within the clamping jaw 13 in a manner known per se. The jaw 13 has a connection option for an external hydraulic line. This is already the case with the prior art in order to be able to connect the present clamping jaw 13, if necessary, to an external hydraulic line. At this hydraulic connection via a hydraulic fitting 16, a bypass line 17 is connected. Below the clamping jaw 13, a further pressure medium cylinder 18 is provided which is acted upon by the pressure medium via the bypass line 17, which is connected to the further pressure medium cylinder 18 via a further hydraulic screw connection 19.
Die Spannbacke 13 ist als zweiarmiger Hebel ausgebildet und über einen Ge¬ lenkbolzen 20 am Schlittenbett 11 gehalten. Der obere Hebelarm der Spannba¬ cke 13 ist mit dem Druckmittelzylinder 15 und der Spindel 14 sowie einer Druck- platte 21 zum Spannen des Werkstücks verbunden. Am unteren Hebelarm derThe clamping jaw 13 is designed as a two-armed lever and held by a Ge steering pins 20 on the carriage bed 11. The upper lever arm of Spannba¬ bridge 13 is connected to the pressure medium cylinder 15 and the spindle 14 and a pressure plate 21 for clamping the workpiece. At the lower lever arm of the

Spannbacke 13 ist eine Zylinderbohrung 22 des weiteren Druckmittelzylinders 18 vorgesehen, in der ein Kolben 23 geführt ist.Clamping jaw 13 is a cylinder bore 22 of the further pressure medium cylinder 18 is provided, in which a piston 23 is guided.
Die zweite Spannbacke 12 ist ebenfalls als zweiarmiger Hebel ausgebildet, wobei der obere Hebelarm eine Druckplatte 24 zum Spannen des Werkstücks trägt. Die Spannbacke 12 ist ihrerseits über einen Gelenkbolzen 25 gelenkig mit dem Schlit¬ tenbett 11 verbunden. Am unteren Hebelarm ist über einen Gelenkbolzen 26 eine Schubstange 27 angebracht, die ihrerseits durch den Kolben 23 des weiteren Druckmittelzylinders 18 betätigbar ist.The second clamping jaw 12 is also designed as a two-armed lever, wherein the upper lever arm carries a pressure plate 24 for clamping the workpiece. The clamping jaw 12 is in turn pivotally connected to the Schlit¬ tenbett 11 via a hinge pin 25. At the lower lever arm, a push rod 27 is attached via a hinge pin 26, which in turn is actuated by the piston 23 of the further pressure medium cylinder 18.
Um die Spannweite des Schraubstocks 10 einstellen zu können, sind in an sich bekannter Weise Bohrungen 29 im Schlittenbett 11 vorgesehen. Entsprechend sind ebenfalls in der Schubstange 27 Bohrungen 30 vorgesehen, so daß jeweils durch Umstecken der Gelenkbolzen 25 und 26 die Spannbacke 12 versetzt und so die Spannweite des Schraubstocks angepaßt werden kann. Ferner ist im Schlittenbett 11 eine der Anzahl der Bohrungen 30 in der Schubstange 27 ent¬ sprechende Anzahl von Bohrungen 31 vorgesehen, deren Durchmesser um ein ausreichendes Maß größer bemessen ist als der Durchmesser des Gelenkbol¬ zens 26, damit dieser sich beim Betätigen der Schubstange 27 frei in der jewei- ligen Bohrungen 31 bewegen kann. Alternativ kann in diesem Bereich in dem Schlittenbett 11 auch ein Langloch vorgesehen sein.In order to adjust the span of the vise 10, holes 29 are provided in the carriage bed 11 in a conventional manner. Accordingly, 27 holes 30 are also provided in the push rod, so that in each case by repositioning the hinge pin 25 and 26, the clamping jaw 12 is offset and so the span of the vise can be adjusted. Further, in the carriage bed 11, one of the number of bores 30 in the push rod 27 ent speaking number of holes 31 is provided whose diameter is dimensioned to a sufficient extent greater than the diameter of the Gelenkbol¬ zens 26, so that this upon actuation of the push rod 27th can move freely in the respective bores 31. Alternatively, a slot may be provided in this area in the carriage bed 11.
Die Gelenkbolzen 25 und 26 sind weiter außen angeordnet, als die Spannflä¬ chen 21 und 24. Beim Spannen des Werkstücks ergeben sich daher auf die Spannflächen 21 und 24 auf das Schlittenbett 11 gerichtete Bewegungskompo¬ nenten, die einen Niederzugeffekt auf das zu spannende Werkstück ausüben.The hinge pins 25 and 26 are arranged farther outward than the clamping surfaces 21 and 24. When clamping the workpiece, therefore, movement components are produced on the clamping surfaces 21 and 24 on the carriage bed 11, which exert a pull-down effect on the workpiece to be clamped ,
Der insoweit beschriebene Schraubstock 10 arbeitet nun wie folgt. Die Druck¬ platte 21 wird zunächst durch Betätigen der Spindel 14 in Anlage an das Werk- stück gebracht. Sodann wird der erste Hydraulikkolben 15 wirksam und bewirktThe vise 10 described so far works as follows. The pressure plate 21 is first brought into contact with the workpiece by actuating the spindle 14. Then, the first hydraulic piston 15 is effective and effected

die Kraftverstärkung der Spannkraft. Gleichzeitig wird der dabei erzeugte Hyd¬ raulikdruck im ersten Druckmittelzylinder 15 über die Bypaßleitung 17 zum wei¬ teren Druckmittelzylinder 18 geführt, so daß die Schubstange 27 über den Ge¬ lenkbolzen 26 die zweite Spannbacke 12 betätigt. Die Druckplatte 24 kippt dabei ebenfalls gegen das Werkstück und entfaltet ihrerseits eine durch den Druck im Druckmittelzylinder 18 sowie die Kolbenfläche des Kolbens 23 und das Verhält¬ nis der Hebelarme an der Spannbacke 12 bestimmte Druckkraft bzw. Spann¬ kraft auf das Werkstück.the power amplification of the clamping force. At the same time, the hydraulic pressure generated in the first pressure medium cylinder 15 is guided via the bypass line 17 to the further pressure medium cylinder 18, so that the push rod 27 actuates the second clamping jaw 12 via the steering bolt 26. The pressure plate 24 also tilts against the workpiece and in turn unfolds a pressure force or clamping force on the workpiece determined by the pressure in the pressure medium cylinder 18 and the piston surface of the piston 23 and the ratio of the lever arms to the clamping jaw 12.
Eine weitere Besonderheit bei dem gezeigten Schraubstock ist, daß die Boh¬ rungen 29 in der neutralen Faser 32 (bezogen auf das Flächenträgheitsmoment) des Schlittenbettes 11 angeordnet sind. Hierdurch werden keine Biegekräfte in das Schlittenbett 11 eingeleitet. Vielmehr wird das Schlittenbett 11 lediglich auf Zug belastet. Die Spannflächen 21 , 24 einerseits und die Schubstange 27 an- derseits sind dabei einander gegenüberliegenden Seiten der neutralen Faser 32 angeordnet.A further special feature of the vise shown is that the bores 29 are arranged in the neutral fiber 32 (relative to the area moment of inertia) of the carriage bed 11. As a result, no bending forces are introduced into the carriage bed 11. Rather, the carriage bed 11 is charged only to train. The clamping surfaces 21, 24 on the one hand and the push rod 27 on the other hand are arranged opposite sides of the neutral fiber 32.
Alternativ zur mechanischen Betätigung über die Spindel 14 kann die Spann¬ kraft aber auch über eine externe Hydraulikversorgung aufgebracht werden. Zu diesem Zweck wird an geeigneter Stelle beispielsweise an der Bypaßleitung 17 ein zusätzlicher Anschluß für die externe Hydraulikversorgung vorgesehen.As an alternative to mechanical actuation via the spindle 14, however, the clamping force can also be applied via an external hydraulic supply. For this purpose, an additional connection for the external hydraulic supply is provided at a suitable location, for example on the bypass line 17.
