Description

Technisches GebietTechnical area

Die vor liegende Erfindung betrifft eine Spannbacke für den bevorzugten Einsatz in einem Maschinenschraubstock, die beim Aufbringen der Spannkraft, das Werkstück gleichzeitig gegen die Auflage unter dem Werkstück, und gegen den Seitenanschlag neben dem Werkstück drückt um dieses exakt zu positionieren Eine solche Spannbache ist beispielsweise aus der EP-A-1 375 069 bekannt. In einer weiterführenden Ausführungsform wird eine Möglichkeit beschrieben, zwei Werkstücke gleichzeitig parallel zu spannen, wobei jedes der Werkstücke beim Spannen gegen eine Parallelunterlage, und gegen einen Seitenanschlag gedrückt wird. Unterschiede bei den Abmessungen in Spannrichtung werden dabei ausgeglichen.The front lying invention relates to a jaw for the preferred use in a machine vise that presses the same time against the support under the workpiece, and against the side stop next to the workpiece during the application of the clamping force to position this exactly such a Spannbache is, for example of the EP-A-1 375 069 known. In a further embodiment, a possibility is described, to clamp two workpieces simultaneously in parallel, wherein each of the workpieces is pressed during clamping against a parallel pad, and against a side stop. Differences in the dimensions in the clamping direction are compensated.

Hintergrund der ErfindungBackground of the invention

Durch den Druck, den herkömmliche Spannbacken beim Spannen im Schraubstock auf das Werkstück ausüben, tendiert das Werkstück sich unkontrolliert von der Auflage abzuheben. Als Folge befindet sich das Werkstück nach dem Spannen in einer relativ zur Auflage, undefinierten Lage.Due to the pressure that conventional clamping jaws exert on the workpiece during clamping in the vice, the workpiece tends to stand out from the support in an uncontrolled manner. As a result, the workpiece is after clamping in a relative to the support, undefined position.

Entsprechend verhält es sich auch beim Einsatz von Seitenanschlägen, die eine seitlich genau definierte Position des Werkstückes nach dem Spannen gewährleisten sollen. Dazu wird das Werkstück von Hand während des Spannvorganges gegen den Seitenanschlag gedrückt. Aufgrund der durch das Spannen auftretenden hohen Kräfte kann jedoch oft nicht verhindert werden, daß sich das Werkstück geringfügig vom Seitenanschlag wieder entfernt. Dies führt zu einer undefinierten Position des Werkstückes, in Bezug auf den Seitenanschlag, nach dem Spannen.The same applies to the use of side stops, which should ensure a laterally well-defined position of the workpiece after clamping. For this purpose, the workpiece is pressed by hand during the clamping operation against the side stop. Due to the high forces occurring due to the clamping, however, it is often impossible to prevent the workpiece from being removed slightly from the side stop. This leads to an undefined position of the workpiece, with respect to the side stop, after tightening.

Gerade bei Werkstücken, die bereits zuvor bearbeitet wurden, und für einen weiteren Bearbeitungsschritt umgespannt werden müssen, führt dies zu Ungenauigkeiten, die oftmals nicht innerhalb der geforderten Maßtoleranzen liegen. So eingespannte Werkstücke können dann nur Bearbeitungsschritten unterzogen werden, die keinen besonderen Genauigkeits-anforderungen genügen müssen. Für genauere Arbeiten wird deshalb auf den Einsatz eines Seitenanschlages verzichtet. Dann muß von der Werkzeugmaschine mittels eines speziell dafür vorgesehenen Werkzeuges die seitliche Körperkante des Werkstückes ermittelt werden, um einen exakten geometrischen Bezug zu der anschließenden Bearbeitung herstellen zu können. Das führt insbesondere bei Serienarbeiten zu erheblichen, weil immer wiederkehrenden Zeitverlusten.Especially for workpieces that have been previously processed, and need to be re-clamped for a further processing step, this leads to inaccuracies that are often not within the required dimensional tolerances. Workpieces clamped in this way can then only be subjected to processing steps which do not have to meet any special requirements for accuracy. For more precise work is therefore dispensed with the use of a side stop. Then must be determined by the machine tool by means of a dedicated tool, the lateral body edge of the workpiece in order to produce an exact geometric relationship to the subsequent processing can. This leads in particular to serial work to considerable, because recurring time losses.

Darüber hinaus kommt einer Reduzierung der Nebenzeiten in den einzelnen Fertigungsschritten immer mehr Bedeutung zu. So finden vielfach Spanneinheiten Verwendung, bei denen mehrere Werkstücke hintereinander gespannt werden, wobei zwischen den Werkstücken schwimmend gelagerte Spannbacken die Spannkraft auf das jeweils nächste Werkstück übertragen. Die Anschaffung solcher Spanneinheiten ist mit größeren Investitionen verbunden, und steht oftmals der Nutzung bereits vorhandener Schraubstöcke gegenüber.In addition, a reduction of non-productive time in the individual production steps is becoming increasingly important. Thus, clamping units are often used in which several workpieces are clamped one behind the other, wherein between the workpieces floating jaws transfer the clamping force to the next workpiece. The purchase of such clamping units is associated with major investments, and is often compared to the use of existing vices.

Die hinlänglich auf dem Markt bekannten Niederzugbacken, dienen dazu, das Werkstück während des Spannvorganges gegen die Parallelunterlagen zu drücken. Das Werkstück wird dadurch parallel zu der Basisführung des Maschinenschraubstockes, und in eine genau definierte Distanz dazu positioniert. Den Einsatz von zeitsparenden Seitenanschlägen, bei genauen Bearbeitungs-anforderungen, unterstützen sie jedoch nicht, da das Werkstück hier nicht gegen den Seitenanschlag gedrückt wird.The well-known on the market Niederzugbacken serve to press the workpiece during the clamping operation against the parallel underlay. The workpiece is thereby positioned parallel to the base guide of the machine vice, and at a well-defined distance thereto. However, they do not support the use of time-saving side stops, with exact machining requirements, since the workpiece is not pressed against the side stop here.

Darstellung der ErfindungPresentation of the invention

Somit ist es Ziel der vorliegenden Erfindung eine Spannbacke zu schaffen, die während des Spannvorganges sowohl das Werkstück auf die Parallelunterlage, als auch gegen den Seitenanschlag drückt, um auch bei genauer, serieller Bearbeitung einen zeitsparenden Seitenanschlag einsetzen zu können. Zusätzlich soll es ermöglicht werden zwei oder mehr Werkstücke nebeneinander spannen zu können bei gleichzeitiger Nutzung der beschriebenen Nieder- und Seitenzugfunktion.Thus, it is an object of the present invention to provide a clamping jaw which presses both the workpiece on the parallel pad, as well as against the side stop during the clamping operation to use a time-saving side stop even with more accurate, serial processing can. In addition, it should be possible to clamp two or more workpieces side by side while using the described low and side train function.

Dazu sieht die vorliegende Erfindung eine fest mit dem Schraubstock verbundene Basisplatte, und eine Spannplatte vor, welche die Spannkraft auf das Werkstück überträgt. Basis- und Spannplatte sind mittels Führungseinheit miteinander verbunden, die die Spannbewegung des Schraubstockes in eine Bewegung der Spannplatte umwandelt, die unter einem horizontalen und einem vertikalen Winkel zur Spannrichtung geneigt, verläuft. Dabei kann die Bewegungsbahn der Spannplatte, je nach Ausführungsform, sowohl geradlinig, als auch gewölbt sein.For this purpose, the present invention provides a firmly connected to the vise base plate, and a clamping plate, which transmits the clamping force to the workpiece. Base and clamping plate are interconnected by means of guide unit, which converts the clamping movement of the vise in a movement of the clamping plate, which is inclined at a horizontal and a vertical angle to the clamping direction. In this case, the path of movement of the clamping plate, depending on the embodiment, both rectilinear, as well as curved.

Basisplatte und Spannplatte werden von Federelementen im ungespannten Zustand von zwischen ihnen angeordneten Federelementen auseinander gedrückt. Begrenzt wird diese Bewegung durch mindestens eine entsprechende geometrische Ausbildung an mindestens einem der beschriebenen Elemente.Base plate and clamping plate are pressed apart by spring elements in the untensioned state of spring elements arranged between them. This movement is limited by at least one corresponding geometric design on at least one of the described elements.

Beim Spannen drückt das Werkstück auf die Spannplatte, die dabei entgegen der Federkraft der Federelemente, parallel zur Basisplatte, auf der bereits beschriebenen Bewegungsbahn hin zur Basisplatte gedrückt wird. Dabei vollzieht die Spannplatte relativ zur Schraubstockbasis eine nach unten und zur Seite gerichtete Bewegung, die das Werkstück gegen die Unterlage und gegen den Seitenanschlag drückt. Das Werkstück liegt dabei an der Spannplatte an und bewegt sich mit der Spannplatte bis es am Seitenanschlag anliegt, bzw. auf der Parallelunterlage aufliegt. Mit dem Berühren von Seitenanschlag bzw. Parallelunterlage ist die Bewegung des Werkstückes quer zur Spannrichtung beendet. Auf diese Weise wird das Werkstück beim Spannen in eine genau definierte und absolut wiederholbare Position gebracht.When clamping the workpiece presses on the clamping plate, which is pressed against the spring force of the spring elements, parallel to the base plate on the already described movement path towards the base plate. In this case, the clamping plate relative to the vise base performs a down and sideways movement that presses the workpiece against the pad and against the side stop. The workpiece rests on the clamping plate and moves with the clamping plate until it rests on the side stop, or rests on the parallel base. By touching the side stop or parallel pad, the movement of the workpiece is completed transversely to the clamping direction. In this way, the workpiece is brought into a precisely defined and perfectly repeatable position during clamping.

Die Bewegungsbahn der Spannplatte relativ zur Basisplatte wird mit dem oben beschriebenen horizontal verlaufenden Winkel und dem oben beschriebenen vertikal verlaufenden Winkel, welche relativ zur Spannrichtung definiert werden, definiert. Mit anderen Worten ist die Richtung der Bewegungsbahn nicht parallel zu der Spannrichtung.The trajectory of the tension plate relative to the base plate is defined with the above-described horizontal angle and the above-described vertical angle defined relative to the tension direction. In other words, the direction of the trajectory is not parallel to the clamping direction.

Die Spannrichtung ist diejenige Richtung, in welche sich die Spannplatte in Richtung einzuspannendem Werkstück verschieben lässt. Das Werkstück wird aufgrund einer Einspannkraft zwischen zwei gegenüberliegenden Spannplatten eingespannt. Die jeweilige Spannkraft weist als Richtungskomponente die Spannrichtung auf.The tensioning direction is the direction in which the tensioning plate can be displaced in the direction of the workpiece to be clamped. The workpiece is clamped between two opposing clamping plates due to a clamping force. The respective clamping force has as a directional component on the clamping direction.

Insbesondere ist die Bewegungsbahn der Spannplatte derart ausgebildet, dass sich die Spannplatte in Richtung einer Unterlage bzw. einer Parallelenunterlage relativ zu der Basisplatte verschieben lässt, sobald die Spannplatte in Richtung Spannrichtung verschoben ist und nach Kontakt mit dem Werkstück eine Spannkraft in Spannkraftrichtung auf die Spannplatte übertragen wird.In particular, the movement path of the clamping plate is designed such that the clamping plate can be displaced in the direction of a pad or a parallel pad relative to the base plate as soon as the clamping plate is moved in the direction of clamping and transferred after contact with the workpiece a clamping force in the clamping force direction on the clamping plate becomes.

Die Parallelunterlage verläuft entlang einer Bodenebene. Die Bodenebene weist eine entsprechende Bodennormale auf. Eine Horizontalebene ist parallel zu der Bodenebene ausgebildet. Eine Vertikalebene ist senkrecht zu der Bodenebene ausgebildet.The parallel underlay runs along a ground plane. The ground level has a corresponding ground normal. A horizontal plane is formed parallel to the ground plane. A vertical plane is formed perpendicular to the ground plane.

Innerhalb der Horizontalebene wird der horizontal verlaufende Winkel definiert. Der horizontal verlaufende Winkel ist derjenige Winkel, welcher den Winkel zwischen der Komponente der Spannrichtung innerhalb der Horizontalebene und der Komponente der Bewegungsbahn innerhalb der Horizontalebene definiert. Mit anderen Worten ist die innerhalb der Horizontalebene liegende Komponente der Bewegungsbahn nicht parallel mit der ist die innerhalb der Horizontalebene liegende Komponente der Spannrichtung.Within the horizontal plane, the horizontal angle is defined. The horizontal angle is that angle which defines the angle between the component of the tensioning direction within the horizontal plane and the component of the movement path within the horizontal plane. In other words, the component of the trajectory lying within the horizontal plane is not parallel with the component of the clamping direction lying within the horizontal plane.

Entsprechend wird innerhalb der Vertikalebene der vertikal verlaufende Winkel definiert. Der in der Vertikalebene verlaufende Winkel ist derjenige Winkel, welcher den Winkel zwischen der innerhalb der Vertikalebene liegende Komponente der Spannrichtung und der innerhalb der Vertikalebene liegende Komponente der Bewegungsbahn definiert. Mit anderen Worten ist die innerhalb der Vertikalebene liegende Komponente der Bewegungsbahn nicht parallel mit der innerhalb der Vertikalebene liegenden Komponente der Spannrichtung innerhalb der Vertikalebene.Accordingly, the vertically extending angle is defined within the vertical plane. The angle in the vertical plane is that angle which defines the angle between the component of the tensioning direction lying within the vertical plane and the component of the movement path lying within the vertical plane. In other words, the component of the trajectory lying within the vertical plane is not parallel with the component of the tensioning direction within the vertical plane lying within the vertical plane within the vertical plane.

Aufgrund der obigen Definition der Bewegungsbahn mittels dem horizontal und vertikal verlaufenden Winkel in der entsprechenden horizontalen und vertikalen Ebene, wird die Bewegungsbahn derart vorweg geben, dass bei der Beaufschlagung der Spannkraft entlang der Spannrichtung sich die Spannplatte in Richtung Parallelunterlage und zusätzlich quer zur Spannrichtung verschiebt, bis das Werkstück auf der Parallelunterlage aufliegt.Due to the above definition of the trajectory by means of the horizontal and vertical angle in the corresponding horizontal and vertical plane, the trajectory will anticipate such that when the clamping force along the clamping direction, the clamping plate shifts in the direction of parallel pad and additionally transverse to the clamping direction, until the workpiece rests on the parallel support.

Je nach Ausführungsform der vorliegenden Erfindung muß sich die Spannplatte, während des Spannvorganges, nicht im gleichen Maß auf die Parallelunterlage und auf den Seitenanschlag zu bewegen. Durch eine entsprechende Ausgestaltung der Führungseinheit lassen sich die Winkel und die Führungsbahn unter denen sich die Spannplatte auf Parallelunterlage und Seitenanschlag zu bewegt, unterschiedlich ausgestalten.Depending on the embodiment of the present invention, the clamping plate, during the clamping operation, does not have to move to the same extent on the parallel pad and on the side stop. By a corresponding configuration of the guide unit, the angle and the guideway under which the clamping plate moves to parallel pad and side stop, can be configured differently.

Gleiche oder ähnliche Komponenten in unterschiedlichen Figuren sind mit gleichen Bezugsziffern versehen. Die Darstellungen in den Figuren sind schematisch.The same or similar components in different figures are provided with the same reference numerals. The illustrations in the figures are schematic.

Fig. 1 zeigt eine dreidimensionale Gesamtansicht eines Schraubstockes 1, auf dem zwei erfindungsgemäße Spannbacken 2 montiert sind. Beim Spannen des Werkstückes, das auf den Parallelunterlagen 50 aufliegt, wird die Spannkraft von der Spannplatte 10 auf das Werkstück übertragen. Dadurch bewegt sich die Spannplatte 10 relativ zur Basisplatte 20 auf der Bewegungsbahn 300, die unter einem horizontal verlaufenden Winkel α, und einem vertikal verlaufenden Winkel β zur Spannrichtung 400 geneigt ist. So vollzieht die Spannplatte 10 relativ zum Werkstück gleichzeitig eine zur Parallelunterlage 50 und zum Seitenanschlag 40 hin gerichtete Bewegung. Aufgrund der Reibungskräfte zwischen Spannplatte 10 und dem Werkstück wird dadurch das Werkstück solange auf der Bewegungsbahn 300 mitbewegt, bis es sowohl am Seitenanschlag 40 und auf der Parallelunterlage 50 anliegt. Für den Rest der Bewegung der Spannplatte 10 reibt diese an dem Werkstück, bis sie mit der dem Werkstück abgewandten Seite auf der Basisplatte 20 anliegt. Fig. 1 shows a three-dimensional overall view of a vise 1, on which two clamping jaws 2 according to the invention are mounted. When clamping the workpiece, which rests on the parallel pads 50, the clamping force is transmitted from the clamping plate 10 to the workpiece. As a result, the clamping plate 10 moves relative to the base plate 20 on the movement path 300, which is inclined at a horizontal angle α, and a vertical angle β to the clamping direction 400. Thus, the clamping plate 10 performs relative to the workpiece at the same time a parallel pad 50 and the side stop 40 directed towards movement. As a result of the frictional forces between the clamping plate 10 and the workpiece, the workpiece is thereby moved on the movement path 300 until it bears against both the side stop 40 and the parallel support 50. For the rest of the movement of the clamping plate 10, this rubs against the workpiece until it rests on the base plate 20 with the side facing away from the workpiece.

Um ein Verkippen des Werkstückes beim Spannen zu verhindern, werden auf beiden Seiten des Werkstückes, mit denen es gespannt wird, erfindungsgemäße Spannbacken eingesetzt. Somit erfolgt die bereits beschriebene seitlich und nach unten gerichtete Kraft, mit der das Werkstück hin zu Seitenanschlag 40 und zu Parallelunterlage 50 gedrückt wird gleichmäßig und gleichgerichtet relativ zum Werkstück.In order to prevent tilting of the workpiece during clamping, clamping jaws according to the invention are used on both sides of the workpiece, with which it is clamped. Thus, the already described laterally and downwardly directed force, with which the workpiece is pressed towards side stop 40 and to parallel support 50, takes place uniformly and rectilinearly relative to the workpiece.

Um eine möglichst vom Kraftverlauf her günstige Position des Seitenanschlages 40 zu schaffen, ist eine Aufnahmeöffnung 24 auf der seitlichen Stirnseite der Basisplatte 20, sowie eine Arretiereinrichtung 41 zum Fixieren des Seitenanschlages 40 angeordnet.In order to create a position of the side stop 40 which is as favorable as possible from the force curve, a receiving opening 24 is located on the side lateral end face of the base plate 20, and a locking device 41 for fixing the side stop 40 is arranged.

Fig. 2 zeigt eine erste bevorzugte Ausführungsform der erfindungsgemäßen Spannbacke. Um eine genaue Ansicht der Funktionseinheit 30 zu erlangen, wurde hier eine Schnittdarstellung gewählt, bei der die erfindungsgemäße Spannbacke 2 unter dem Winkel β geschnitten wurde. Fig. 2 shows a first preferred embodiment of the clamping jaw according to the invention. In order to obtain a precise view of the functional unit 30, a sectional illustration was selected here in which the clamping jaw 2 according to the invention was cut at the angle β.

Die Bewegungsbahn 300 ist hier geradlinig ausgebildet, und ist durch den horizontal verlaufenden Winkel α und den vertikal verlaufenden Winkel β zur Spannrichtung 400 geneigt. Somit bewegt sich die Spannplatte 10 auf einer schräg im Raum verlaufenden Gerade, die gleichzeitig auf die Basisplatte 20, den Anschlag 40 und vertikal nach unten gerichtet ist.The movement path 300 is here rectilinear, and is inclined by the horizontally extending angle α and the vertical angle β to the clamping direction 400. Thus, the clamping plate 10 moves on an obliquely extending in space straight line, which is simultaneously directed to the base plate 20, the stop 40 and vertically downwards.

Als Führungselement 31 ist hier eine zylindrische Welle vorgesehen, die mittels einer Abstufung und einem Gewinde fix mit der Spannplatte 10 verbunden ist. Auf der, der Spannplatte 10 abgewandten Seite des Führungselements 31 ist eine stufenartige Verjüngung vorgesehen, an der sich die Rückstellfeder 32 auf der, der Spannplatte 10 zugewandten Seite, abstützt. Auf der Seite der Basisplatte 20 stützt sich die Rückstellfeder 32 auf der, der Spannplatte 10 zugewandten Seite des Vorsprunges 21, der Führungsgeometrie 22, ab.As a guide member 31, a cylindrical shaft is provided here, which is connected by means of a gradation and a thread fixed to the clamping plate 10. On the side facing away from the clamping plate 10 of the guide member 31, a step-like taper is provided, at which the return spring 32 on the, the clamping plate 10 facing side, is supported. On the side of the base plate 20, the return spring 32 is supported on the, the clamping plate 10 facing side of the projection 21, the guide geometry 22 from.

Begrenzt wird die durch die Rückstellfeder 32 hervorgerufene Rückstellbewegung durch das Begrenzungselement 33, das hier als handelsüblicher Sicherungsring vorgesehen ist, der in eine dafür vorgesehene Nut des Führungselements 31 eingreift, und auf der, der Spannplatte 10 abgewandten Seite des Vorsprunges 21 der Führungsgeometrie 22 anliegt. Sobald beim Spannen das Werkstück gegen die Spannplatte 10 drückt, wird diese entgegen der Federkraft der Rückstellfeder 32, auf der Bewegungsbahn 300 zur Basisplatte 20 hin gedrückt. Damit hebt das Begrenzungselement 33 von dem Vorsprung 21 ab.The restoring movement caused by the restoring spring 32 is limited by the delimiting element 33, which is provided here as a commercially available securing ring, which engages in a groove of the guide element 31 provided for this purpose and on which the clamping plate 10 faces away from the projection 21 of the guide geometry 22. As soon as the workpiece presses against the clamping plate 10 during clamping, this is against the spring force of the return spring 32, on the path of movement 300 pressed to the base plate 20 out. Thus, the limiting element 33 lifts off from the projection 21.

Um ein Verkippen der Spannplatte 10 beim Spannen des Werkstückes zu verhindern, sind hier die Führungseinheiten 30 jeweils an den Ecken der Spannbacke angeordnet.In order to prevent tilting of the clamping plate 10 during clamping of the workpiece, here the guide units 30 are respectively arranged at the corners of the clamping jaw.

Da die Spannplatte 10 beim Spannen des Werkstückes, am Ende der Bewegungsbahn 300, auf der Basisplatte 20 aufliegt, wird die gesamte Spannkraft des Schraubstockes 1 nie nur von den Führungseinheiten 30 übertragen. Vielmehr wird nur derjenige Teil der Kraft übertragen, der von den Rückstellfedern 32 auf die Spannplatte 10 wirkt. Dadurch kann hier die Ausdehnung in Spannrichtung 400 der Spannplatte 10 entsprechend reduziert werden.Since the clamping plate 10 during clamping of the workpiece, at the end of the movement path 300, rests on the base plate 20, the entire clamping force of the vice 1 is never transmitted only by the guide units 30. Rather, only that part of the force is transmitted, which acts from the return springs 32 on the clamping plate 10. As a result, the extent in the clamping direction 400 of the clamping plate 10 can be reduced accordingly here.

Fig. 3 zeigt eine Schnittdarstellung einer weiteren Ausführungsform der erfindungsgemäßen Spannbacke. Auch hier, wie in Fig. 2, verläuft der Schnitt, wegen der besseren Anschaulichkeit unter dem Winkel β zur horizontalen Ebene. Diese Ausführungsform dient zum Spannen von zwei Werkstücken, die in Spannrichtung 400 unterschiedliche Abmessungen haben können. Fig. 3 shows a sectional view of another embodiment of the clamping jaw according to the invention. Again, as in Fig. 2 , The section runs, because of better clarity at the angle β to the horizontal plane. This embodiment is used for clamping two workpieces that can have different dimensions in the clamping direction 400.

Die Spannplatte 10 ist hier geteilt in Spannplatte 10a und 10b, wobei der Spannplatte 10a die Bewegungsbahn 300a, und der Spannplatte 10b der Bewegungsbahn 300b zugeordnet ist. Beide Bewegungsbahnen 300a und 300b können parallel zueinander verlaufen. In dieser Ausgestaltungsform jedoch wurden die beiden Bewegungsbahnen so gewählt, daß sie an einer vertikalen, entlang der Spannrichtung 400 verlaufenden Ebene gespiegelt wurden. Dadurch bewegt sich die Spannplatte 10a zur einen Seite der Spannbacke 2 und die Spannplatte 10b zur anderen Seite der Spannbacke 2. Da die Bewegungsbahnen 300a und 300b nicht nur zu einer vertikalen, in Spannrichtung 400 verlaufenden Ebene, sondern auch zu einer horizontal verlaufenden Ebene, geneigt sind, vollziehen beiden Spannplatten 10a und 10b beim Spannen auch gleichzeitig eine Relativbewegung in Bezug auf das Werkstück, senkrecht nach unten.The clamping plate 10 is here divided into clamping plate 10a and 10b, wherein the clamping plate 10a, the movement path 300a, and the clamping plate 10b of the movement path 300b is assigned. Both trajectories 300a and 300b may be parallel to each other. In this embodiment, however, the two trajectories were chosen so that they were mirrored on a vertical, running along the clamping direction 400 level. As a result, the clamping plate 10a moves to one side of the clamping jaw 2 and the clamping plate 10b to the other side of the clamping jaw 2. Since the movement paths 300a and 300b not only to a vertical, extending in the clamping direction 400 level, but also to a horizontal extending plane, are inclined, perform both clamping plates 10a and 10b during clamping at the same time a relative movement with respect to the workpiece, vertically downwards.

Senkrecht zur Spannrichtung 400 ist ein Stellglied 60 angeordnet, das relativ zu den Spannplatten 10a und 10b und relativ zur Basisplatte 20, quer zur Spannrichtung 400 auf einer horizontal verlaufenden Bahn, beweglich ist. Auf der, der Funktionseinheit 30 zugewandten Seite des Stellgliedes 60 sind Vertiefungen 61 angeordnet, die jeweils einer Funktionseinheit 30 zugeordnet sind. Jeweils eine Flanke 65 der Vertiefung 61 ist zur Spannrichtung 400 geneigt.Perpendicular to the clamping direction 400, an actuator 60 is arranged which is movable relative to the clamping plates 10a and 10b and relative to the base plate 20, transverse to the clamping direction 400 on a horizontally extending path. On the, the functional unit 30 facing side of the actuator 60 recesses 61 are arranged, which are each assigned to a functional unit 30. Each flank 65 of the recess 61 is inclined to the clamping direction 400.

Das Begrenzungselement 33 ist endseitig konisch ausgeformt und greift in die Vertiefung 61 ein. Durch den Spannvorgang wird die Spannplatte 10b zur Basisplatte 20 gedrückt, wodurch der konische Teil des Begrenzungselementes 33 entlang der zur Spannrichtung 400 geneigten Flanke 65 gleitet. Dadurch wird das Stellglied 60 quer zur Spannrichtung 400 bewegt.The limiting element 33 is conically shaped at the end and engages in the recess 61 a. By the clamping operation, the clamping plate 10b is pressed to the base plate 20, whereby the conical part of the limiting element 33 slides along the 64 inclined to the clamping direction edge 65. As a result, the actuator 60 is moved transversely to the clamping direction 400.

Fig. 4 zeigt eine dreidimensionale Explosionsansicht der erfindungsgemäßen Spannbacke. Die Vertiefungen in dem Stellglied 60 sind spiegelbildlich zu einer vertikal verlaufenden Ebene ausgebildet. Die Begrenzungselemente 33 der, der Spannplatte 10a zugeordneten Funktionseinheiten greifen ihrerseits in die gespiegelten Vertiefungen 63 und 64 des Stellgliedes 60 ein. Das Stellglied 60 bewegt sich dadurch solange bis sich die Spannkraft auf die beide Spannplatten 10a und 10b ausgeglichen hat. Fig. 4 shows a three-dimensional exploded view of the clamping jaw according to the invention. The recesses in the actuator 60 are mirror-inverted to a vertical plane. The limiting elements 33 of the, the clamping plate 10 a associated functional units in turn engage in the mirrored recesses 63 and 64 of the actuator 60 a. The actuator 60 thereby moves until the clamping force on the two clamping plates 10a and 10b has been compensated.

Somit gleichen automatisch die beiden Spannplatten 10a und 10b unterschiedliche Abmessungen in Spannrichtung 400 der zu spannenden Werkstücke aus, so daß stets der gleiche Spanndruck auf beide Werkstücke ausgeübt wird.Thus automatically compensate the two clamping plates 10a and 10b different dimensions in the clamping direction 400 of exciting workpieces, so that always the same clamping pressure is exerted on both workpieces.

Fig. 5 zeigt eine erfindungsgemäße Spannbacke in Frontansicht, bei der aus Anschauungsgründen die Spannplatte nicht dargestellt ist. Die Basisplatte 20 hat hier längliche, schräg zur Horizontalen verlaufende Vertiefungen 23, in denen jeweils eine Zylinderrolle 70 angeordnet ist. Fig. 5 shows a clamping jaw according to the invention in a front view, in which, for illustrative purposes, the clamping plate is not shown. The base plate 20 has here elongated obliquely to the horizontal recesses 23, in each of which a cylindrical roller 70 is arranged.

Fig. 6 zeigt die erfindungsgemäße Spannbacke aus Fig. 5, in einer dreidimensionalen Schnittansicht. Der Schnitt verläuft dabei quer zu den Zylinderrollen 70. Begrenzungselement 33 und Rückstellfeder 32 sind hier nicht dargestellt. Jeder Vertiefung 23 der Basisplatte 20, in der eine Zylinderrolle 70 angeordnet ist, ist eine Ausnehmung 13 der Spannplatte 10 zugeordnet. Fig. 6 shows the jaw of the invention Fig. 5 in a three-dimensional sectional view. The section runs transversely to the cylindrical rollers 70. The limiting element 33 and the return spring 32 are not shown here. Each recess 23 of the base plate 20, in which a cylindrical roller 70 is arranged, is associated with a recess 13 of the clamping plate 10.

Im ungespannten Zustand befindet sich die Spannplatte 10 in einer Position, in der die Zylinderrolle 70 den Rand 12 der Ausnehmung 13 berührt. Beim Spannen bewegt sich der Rand 12, der Ausnehmung 13, auf dem Umfang der Zylinderrolle 70, bis die, der Basisplatte 20 zugewandte Seite der Spannplatte 10 auf der, der Spannplatte 10 zugewandten Seite der Basisplatte 20 anschlägt. Dadurch entsteht eine gekrümmte Bewegungsbahn 300, die in jedem Bereich ihres Verlaufes, unter einem horizontal verlaufenden Winkel α, und einem vertikal verlaufenden Winkel β zur Spannrichtung 400 geneigt ist.In the untensioned state, the clamping plate 10 is in a position in which the cylindrical roller 70 contacts the edge 12 of the recess 13. During clamping, the edge 12, the recess 13, moves on the circumference of the cylindrical roller 70 until the, the base plate 20 facing side of the clamping plate 10 on the, the clamping plate 10 facing side of the base plate 20 abuts. This results in a curved path of movement 300, which is inclined in each region of its course, at a horizontal angle α, and a vertical angle β to the clamping direction 400.

Auch bei diesem Ausführungsbeispiel der vorliegenden Erfindung kann die Spannplatte 10 in zwei Spannplatten 10a und 10b geteilt werden und mittels eines Stellgliedes 60 die Relativbewegungen der Spannplatten 10a und 10b koordiniert werden, so daß zwei Werkstücke mit verschiedenen Abmessungen in Spannrichtung, gespannt werden können.Also in this embodiment of the present invention, the clamping plate 10 can be divided into two clamping plates 10a and 10b and by means of an actuator 60, the relative movements of the clamping plates 10a and 10b are coordinated, so that two workpieces with different dimensions in the clamping direction, can be stretched.

Entsprechend dem Ausführungsbeispiel in Fig. 5 und Fig. 6 lassen sich eine Vielzahl von Wirkgeometrien finden, die dem Hauptanspruch genügen. Die Bewegungsbahn kann dabei kreisrund, unter verschiedenen Radien mehrfach gekrümmt, gerade, oder auch eine Mischung aus den verschiedenen Möglichkeiten sein.According to the embodiment in Fig. 5 and Fig. 6 can be found a variety of effective geometries that meet the main claim. The trajectory can be circular, several times under different radii curved, straight, or even a mixture of the different possibilities.

Fig. 7 zeigt eine schematische Darstellung eines Schraubstocks 1 gemäß einer beispielhaften Ausführungsform der vorliegenden Erfindung, in welchem mehrere Werkstücke 700 gleichzeitig eingespannt werden können. Fig. 7 shows a schematic representation of a vise 1 according to an exemplary embodiment of the present invention, in which a plurality of workpieces 700 can be clamped simultaneously.

Der Schraubstock 1 weist drei Spannbacken 2 auf. Jede der Spannbacken 2 ist verschiebbar auf einem Basiselement 701 angeordnet. Hierzu bildet das Basiselement 701 eine Führungsschiene aus, auf welcher entsprechende Schlitten 702 der entsprechenden Spannbacken 2 verschiebbar gekoppelt werden können. Die äußeren Spannbacken 2 sind dabei jeweils in Richtung der mittleren Spannbacke 2 entlang einer Verstellrichtung 703 verschiebbar. Somit kann der Abstand zwischen den äußeren Spannbacken 2 und der mittleren Spannbacke 2 reduziert werden, so dass zwischen den entsprechenden Spannbacken 2 jeweils Werkstücke 701 einspannbar sind.The vise 1 has three jaws 2. Each of the jaws 2 is slidably disposed on a base member 701. For this purpose, the base member 701 forms a guide rail on which corresponding carriage 702 of the corresponding clamping jaws 2 can be slidably coupled. The outer clamping jaws 2 are in each case displaceable in the direction of the middle clamping jaw 2 along an adjustment direction 703. Thus, the distance between the outer jaws 2 and the middle jaw 2 can be reduced, so that between the corresponding clamping jaws 2 each workpiece 701 are clamped.

Das Basiselement 701 weist eine Oberfläche auf, welche zu dem einzuspannenden Werkstück 700 gerichtet ist. Die Oberfläche des Basiselements bildet die Parallelunterlage 50. Zu der Ebene, in welcher die Parallelunterlage 50 verläuft, wird die Normale n dargestellt.The base member 701 has a surface that faces the workpiece 700 to be clamped. The surface of the base member forms the parallel pad 50. To the plane in which the parallel pad 50 extends, the normal n is shown.

Jede Spannbacke 2 weist eine entsprechende Basisplatte 20 auf. Die Basisplatte 20 kann fest als Teil der Schraubstocks 1 mit dem Basiselement 701 verbunden werden und entlang der Verstellrichtung 703 verschiebbar sein. An den entsprechenden Basisplatten 20 sind jeweils zwei Spannplatten 10a, 10b verschiebbar angeordnet.Each jaw 2 has a corresponding base plate 20. The base plate 20 can be fixedly connected as part of the vices 1 with the base member 701 and be displaceable along the adjustment direction 703. At the corresponding base plates 20 each two clamping plates 10a, 10b are arranged displaceably.

Jede Spannplatte 10a, 10b ist mittels einer Funktionseinheit 30, welche als Führungselement 31 z.B. eine Führungsschraube oder -bolzen aufweist, verschiebbar an der entsprechenden Basisplatte 20 angeordnet.Each clamping plate 10a, 10b is arranged displaceably on the corresponding base plate 20 by means of a functional unit 30 which has, for example, a guide screw or bolt as guide element 31.

Das Führungselement 31 ist derart ausgerichtet, dass bei Verschiebung der entsprechende Spannplatte 10a, 10b entlang dem Führungselement 31 die entsprechende Spannplatte 10a, 10b entlang der Bewegungsbahn 300 verschoben wird.The guide element 31 is aligned such that upon displacement of the corresponding clamping plate 10a, 10b along the guide element 31, the corresponding clamping plate 10a, 10b is displaced along the movement path 300.

Jedes der Spannplatten 10a, 10b weist eine zum Werkstück 700 gerichtete Spannfläche auf, welche eine Normale aufweist die parallel zu der Spannrichtung 400 ausgerichtet ist. Wird ein Werkstück 700, wie in Fig. 7 dargestellt, zwischen drei gegenüberliegenden Spannplatten 10a eingespannt, indem die äußere Spannbacke 2 in Richtung der mittleren Spannbacke 2 entlang der Verschieberichtung 703 verschoben wird, wird eine Spannkraft auf die entsprechenden Spannplatten 10a, 10b übertragen. Daraufhin verschiebt sich die entsprechenden Spannplatte 10a in Richtung der Bewegungsbahn 300, d. h. in Richtung Basiselement 701 und in Richtung des Seitenanschlags 40, bis das Werkstück 700 plan auf der Parallelunterlage 50 und dem Seitenanschlag 40 in einer definierten und gewünschten Position anliegt. Somit ist ein Nachjustieren der Lage des Werkstücks 700 nicht notwendig.Each of the clamping plates 10a, 10b has a clamping surface directed towards the workpiece 700, which has a normal which is aligned parallel to the clamping direction 400. Will a workpiece 700, as in Fig. 7 shown, clamped between three opposing clamping plates 10a by the outer jaw 2 is moved in the direction of the middle jaw 2 along the direction of displacement 703, a clamping force is transmitted to the corresponding clamping plates 10a, 10b. The corresponding clamping plate 10a then shifts in the direction of the movement path 300, ie in the direction of the base element 701 and in the direction of the side stop 40, until the workpiece 700 lies flat against the parallel support 50 and the side stop 40 in a defined and desired position. Thus, a readjustment of the position of the workpiece 700 is not necessary.

Die Seitenanschläge 40 sind jeweils an den äußeren Randbereichen der entsprechenden Basisplatten 20 beispielsweise mittels einer Schraubverbindung befestigt.The side stops 40 are each attached to the outer edge regions of the corresponding base plates 20, for example by means of a screw connection.

In Fig. 7 ist beispielsweise lediglich ein Werkstück 700 in einem eingespannten Zustand zwischen der mittleren Spannbacke 2 und einer links äußeren Spannbacke 2 dargestellt. Entsprechend können zwischen zwei weiteren dargestellten und gegenüber angeordneten Spannplatten 10a, 10b entsprechende weitere Werkstücke 700 befestigt werden.In Fig. 7 For example, only a workpiece 700 in a clamped state between the middle jaw 2 and a left outer jaw 2 is shown. Accordingly, between two further illustrated and oppositely disposed clamping plates 10a, 10b corresponding further workpieces 700 are attached.

Die Bewegungsbahn 300 der entsprechenden Spannplatten 10a, 10b relativ zur Basisplatte bzw. der Parallelunterlage 50 wird mit dem oben beschriebenen horizontal verlaufenden Winkel α und dem oben beschriebenen vertikal verlaufenden Winkel β (siehe z.B. Fig. 1), welche relativ zur Spannrichtung 400 definiert werden, definiert. Mit anderen Worten ist die Richtung der Bewegungsbahn 300 nicht parallel zu der Spannrichtung 400.The trajectory 300 of the corresponding clamping plates 10a, 10b relative to the base plate or the parallel pad 50 is with the above described horizontally extending angle α and the above-described vertical angle β (see, eg Fig. 1 ), which are defined relative to the clamping direction 400 defined. In other words, the direction of the movement path 300 is not parallel to the tensioning direction 400.

Die Spannrichtung 400 ist diejenige Richtung, in welche sich die Spannplatten 10a, 10b in Richtung einzuspannendem Werkstück verschieben lassen. Das Werkstück 700 wird aufgrund einer Einspannkraft zwischen zwei gegenüberliegenden Spannplatten 10a, 10b eingespannt. Die jeweilige Spannkraft weist als Richtungskomponente die Spannrichtung 400 auf.The clamping direction 400 is the direction in which the clamping plates 10a, 10b can be displaced in the direction of the workpiece to be clamped. The workpiece 700 is clamped due to a clamping force between two opposite clamping plates 10a, 10b. The respective clamping force has the direction of tension 400 as a directional component.

Insbesondere ist die Bewegungsbahn 300 der Spannplatten 10a, 10b ist derart ausgebildet, dass sich die entsprechenden Spannplatte 10a, 10b in Richtung einer der Parallelenunterlage 50 relativ zu der entsprechenden Basisplatte 20 verschieben lässt, sobald die Spannplatte 10a, 10b in Richtung Spannrichtung 400 verschoben ist und nach Kontakt mit dem Werkstück 700 eine Spannkraft in Spannkraftrichtung 400 auf die entsprechenden Spannplatten 10a, 10b übertragen wird.In particular, the movement path 300 of the clamping plates 10a, 10b is designed such that the corresponding clamping plate 10a, 10b can be displaced in the direction of one of the parallel support 50 relative to the corresponding base plate 20 as soon as the clamping plate 10a, 10b is displaced in the clamping direction 400 and after contact with the workpiece 700, a clamping force in the clamping force direction 400 is transmitted to the corresponding clamping plates 10a, 10b.

Die Parallelunterlage 50 verläuft entlang einer Bodenebene. Die Bodenebene weist die entsprechende Bodennormale n auf. Eine Horizontalebene ist parallel zu der Bodenebene ausgebildet. Eine Vertikalebene ist senkrecht zu der Bodenebene ausgebildet.The parallel pad 50 runs along a ground plane. The ground plane has the corresponding ground normal n. A horizontal plane is formed parallel to the ground plane. A vertical plane is formed perpendicular to the ground plane.

Innerhalb der Horizontalebene wird der horizontal verlaufende Winkel α definiert. Der horizontal verlaufende Winkel α ist derjenige Winkel, welcher den Winkel zwischen der innerhalb der Horizontalebene liegenden Komponente der Spannrichtung 400 und der innerhalb der Horizontalebene liegenden Komponente der Bewegungsbahn 300 innerhalb der Horizontalebene definiert. Mit anderen Worten ist die innerhalb der Horizontalebene liegende Komponente der Bewegungsbahn 300 nicht parallel mit der innerhalb der Horizontalebene liegenden Komponente der Spannrichtung 400.Within the horizontal plane, the horizontal angle α is defined. The horizontally extending angle α is that angle which defines the angle between the component of the clamping direction 400 lying within the horizontal plane and the component of the movement path 300 lying within the horizontal plane within the horizontal plane. In other words, it is within the horizontal plane Component of the trajectory 300 is not parallel with the lying within the horizontal plane component of the clamping direction 400.

Entsprechend wird innerhalb der Vertikalebene der vertikal verlaufende Winkel β definiert. Der in der Vertikalebene verlaufende Winkel β ist diejenige Winkel, welcher den Winkel zwischen der innerhalb der Vertikalebene liegenden Komponente der Spannrichtung 400 und der innerhalb der Vertikalebene liegenden Komponente der Bewegungsbahn 300 definiert. Mit anderen Worten ist die innerhalb der Vertikalebene liegende Komponente der Bewegungsbahn 300 nicht parallel mit der innerhalb der Vertikalebene liegende Komponente der Spannrichtung 400.Accordingly, within the vertical plane, the vertical angle β is defined. The angle β in the vertical plane is the angle which defines the angle between the component of the clamping direction 400 lying within the vertical plane and the component of the movement path 300 lying within the vertical plane. In other words, the component of the movement path 300 lying within the vertical plane is not parallel with the component of the tensioning direction 400 lying within the vertical plane.

Fig. 8 zeigt eine Spannbacke 2 des Schraubstocks aus Fig. 7. die Spannplatten 10a, 10b verschieben sich jeweils entlang der Bewegungsbahn 300 nach unten, d.h. in Richtung Parallelunterlage 50, und nach außen, in Richtung Seitenanschlag 40, wenn entlang der Spannrichtung 400 eine Spannkraft übertragen wird. Fig. 8 shows a jaw 2 of the vise Fig. 7 , the clamping plates 10a, 10b each move along the movement path 300 downwards, ie in the direction parallel pad 50, and outwards, in the direction of side stop 40, when along the clamping direction 400, a clamping force is transmitted.

Fig. 9 zeigt eine Schnittdarstellung der Spannbacke aus Fig. 8. In der Schnittdarstellung wird die Ausbildung der Funktionseinheiten 30 dargestellt. Die Basisplatte 20 weist entsprechende Bohrungen auf, in welchen jeweils eines der Führungselemente 31, welche als Bolzen ausgebildet sind, eingreifbar ist. Entsprechend weist die jeweilige Spannplatte 10a, 10b eine Bohrung auf, in welche ein weiterer Abschnitt des Führungselements 31 aufnehmbar ist. Die Spannplatte 10a, 10b ist dabei relativ zu dem Führungselementen 31 verschiebbar angeordnet. Aufgrund der Ausrichtung der Führungselemente 31 kann die entsprechende Spannplatte 10a, 10b entlang der Bewegungsbahn 300 relativ zu der Basisplatte 20 verschoben werden. Fig. 9 shows a sectional view of the jaw Fig. 8 , In the sectional view, the formation of the functional units 30 is shown. The base plate 20 has corresponding holes, in each of which one of the guide elements 31, which are designed as bolts, is engageable. Accordingly, the respective clamping plate 10a, 10b has a bore into which a further section of the guide element 31 can be received. The clamping plate 10a, 10b is arranged displaceable relative to the guide elements 31. Due to the orientation of the guide elements 31, the corresponding clamping plate 10a, 10b can be displaced along the movement path 300 relative to the base plate 20.

Alternativ kann das Führungselement 31 als Gewindeschraube ausgebildet sein und in eine Gewindebohrung der Basisplatte 20 eingreifen. Somit kann beispielsweise die Gewindeschraube als Spannschraube ausgebildet sein, so dass mittels eines Einschraubens der Spannschraube in die Basisplatte 20 die entsprechende Spannplatte 10a, 10b in Richtung Bewegungsbahn 300 verschoben wird und gleichzeitig in Richtung Spannrichtung 400 hin zu dem einzuspannendem Werkstück 700. Somit kann das Werkstück zunächst zwischen zwei gegenüberliegende Spannplatten 10a, 10b eingelegt werden und anschließend nach Festziehen der Gewindeschrauben die entsprechenden Spannplatten 10a, 10b in Richtung Spannrichtung 400 und in Richtung der Bewegungsbahn 300 verschoben werden, bis das Werkstück 700 zwischen zwei gegenüberliegenden Spannplatten 10a, 10b eingespannt ist.Alternatively, the guide element 31 may be formed as a threaded screw and engage in a threaded bore of the base plate 20. Thus, for example, the threaded screw may be formed as a clamping screw, so that by means of screwing the clamping screw in the base plate 20, the corresponding clamping plate 10a, 10b is moved in the direction of movement path 300 and at the same time in the direction of clamping direction 400 toward the einzuspannendem workpiece 700. Thus, the workpiece are first inserted between two opposite clamping plates 10a, 10b and then after tightening the screws the corresponding clamping plates 10a, 10b are moved in the direction of tensioning direction 400 and in the direction of the movement path 300 until the workpiece 700 is clamped between two opposing clamping plates 10a, 10b.

Zwischen den entsprechenden Spannplatten 10a, 10b und der entsprechenden Basisplatte 20 kann eine Rückstellfeder 32 der Funktionseinheit 30 angeordnet werden. Die Rückstellfeder 32 generiert eine Rückstellkraft, welche entgegen der Richtung der Bewegungsbahn 300 wirkt. Somit kann nach Entlastung der entsprechenden Spannplatte 10a, 10b diese wieder in den Ausgangszustand aufgrund der Rückstellkraft verschoben werden.Between the corresponding clamping plates 10a, 10b and the corresponding base plate 20, a return spring 32 of the functional unit 30 can be arranged. The return spring 32 generates a restoring force, which counteracts the direction of the movement path 300. Thus, after relieving the corresponding clamping plate 10a, 10b, these are moved back to the initial state due to the restoring force.

In Fig. 9 ist ferner dargestellt, dass zwischen den entsprechenden Spannplatten 10a, 10b und der Basisplatte 20 eine Berührfläche 901 ausgebildet wird. Die Berührfläche 901 weist eine Normale auf, welche nicht parallel zu der Bewegungsbahn 300 und nicht parallel zu der Spannrichtung 400 ist. Dies hat zur Folge, dass die Spannkraft, welche in Richtung Spannrichtung 400 in die entsprechenden Spannplatten 10a, 10b eingeleitet wird, zumindest teilweise in eine Kraftrichtung der Bewegungsbahn 300 umgeleitet bzw. umgelenkt wird, wobei diese Kraft in Richtung der Bewegungsbahn 300 die Spannplatten 10a, 10b zum Bewegen in Richtung der Bewegungsbahn 300 veranlasst.In Fig. 9 It is further shown that between the corresponding clamping plates 10a, 10b and the base plate 20, a contact surface 901 is formed. The contact surface 901 has a normal which is not parallel to the movement path 300 and not parallel to the tension direction 400. This has the consequence that the clamping force, which is introduced in the direction of the clamping direction 400 in the corresponding clamping plates 10a, 10b, at least partially diverted or deflected in a direction of force of the movement path 300, this force in the direction of the movement path 300, the clamping plates 10a, 10b for moving in the direction of the movement path 300 causes.

Fig. 10 zeigt eine Spannbacke aus Fig. 8, ohne die Beaufschlagung mit einer Spannkraft. In Fig. 10 wird deutlich, dass in Richtung Spannrichtung 401 ein Abstand zwischen den entsprechenden Spannplatten 10a, 10b und der Basisplatte 20 besteht. Nach der Beaufschlagung der Spannkraft in Richtung Spannrichtung 401 ermöglicht dieser Abstand ein Bewegen der entsprechenden Spannplatten 10a, 10b in Richtung der entsprechenden Basisplatte 20 bei gleichzeitiger Bewegung der entsprechenden Spannplatte 10a, 10b in Richtung Bewegungsbahn 300. Fig. 10 shows a jaw Fig. 8 , without the application of a clamping force. In Fig. 10 It is clear that in the direction of clamping direction 401, a distance between the corresponding clamping plates 10a, 10b and the base plate 20 is made. After the application of the clamping force in the direction of the clamping direction 401, this distance enables a movement of the corresponding clamping plates 10a, 10b in the direction of the corresponding base plate 20 with simultaneous movement of the corresponding clamping plate 10a, 10b in the direction of movement path 300.

Fig. 11 zeigt eine Spannbacke aus Fig. 8, in welcher die linke Spannplatte 10a mit einer Spannkraft beaufschlagt ist und entsprechend entlang der Bewegungsrichtung der 100 verschoben ist, während die rechte Spannplatte 10b nicht mit der Spannkraft beaufschlagt ist und in der Ausgangsposition verharrt. Fig. 11 shows a jaw Fig. 8 in which the left clamping plate 10a is acted upon by a clamping force and is correspondingly displaced along the direction of movement of the 100, while the right clamping plate 10b is not acted upon by the clamping force and remains in the starting position.
