- the bed has a planar reference surface extending transversely to the clamping plates and between them, that at least two adjacent clamping surfaces extending in the direction of the reference surface are formed on the bed, of which a first Clamping surface is inclined relative to the reference surface and the second clamping surface is inclined relative to the reference surface in opposite directions, and that at least two clamping surfaces adjacent clamping surfaces are formed on the second clamping jaw, of which the first clamping surface parallel to the first clamping surface and the second clamping surface parallel to the second Clamping surface extends.
- Another jig is in the EP 0 362 753 disclosed. It serves to hold workpieces and has at a distance relative to each other adjustable Clamping jaws, which have mutually facing clamping surfaces.
- a workpiece support is available. It is provided at the one or more clamping surfaces of the clamping jaws adjustable from the workpiece to be clamped and acted in the clamping direction pull-down device. This has a over the clamping surface protruding and obliquely to the workpiece support nevendes pull-down.
- this pull-down element is acted upon and pivots obliquely downwards in the direction of the workpiece support, wherein the workpiece is either taken along or is subjected to force in this direction, so that a secure abutment takes place on the support.
- the German patent application DE 43 41 744 A1 shows a thermoforming system for clamping devices on workpiece processing machines, consisting of two opposing parts, a stop - thermoforming clamp with fixed jaws and a thermoformer with movable jaws, between which the workpiece to be machined is clamped, with a stop thermoforming clamp is present as a stationary stop member which consists of a jaw body which is arranged on a holding plate, wherein the jaw body is equipped for clamping a workpiece with protective jaws, which has a vertical clamping surface to the holding plate, wherein the jaw body rests against a support and with an elastically bendable part relative to the holding plate and has a shape, whereby upon application of a force acting parallel to the holding plate thrust force on the protective jaws on the holding plate directed force, which is greater than the lifting force is transmitted to the workpiece.
- DD 54 958 A is a pull-down jaw for tool clamps, especially for vices or the like.
- the Niederzugbacke has three as flexurally elastic, oppositely arranged webs trained functional elements, which are divided by parallel slots.
- a main requirement for an optimal clamping system is a clamping of a workpiece, which must not move away from the vise bed during clamping and in the clamped state.
- the workpiece becomes runny water up to pressures of 100 bar applied to rinse chips or waste material away. This can lead to vibrations of the clamped workpiece, which can negatively affect the exact clamping of the workpiece.
- the problem with the prior art is that the required strength when clamping a tool is not achieved due to more demanding application requirements.
- the workpieces become larger, for example, so that a clamping device of the present type must have the ability to optimally clamp workpieces that are relatively large to the size of the clamping tool.
- wire erosion machines have higher working speeds. This requires higher water pressures for the removal of the resulting chips, which in turn has a higher load on the workpiece result.
- Another disadvantage is the use of protruding workpieces due to low load possibility.
- a protruding workpiece generates a certain bending moment, which can negatively burden the clamping force.
- the invention is solved by the characterizing part of claim 1.
- a displacement of the point of application of the clamping force is achieved in parallel to the vise bed with the result of an increase in the torque which acts on the workpiece.
- the strength of the clamping in the direction perpendicular to the vise bed is increased.
- the essential feature is the achievement of a maximum load capacity.
- the load capacity is given by the maximum bending moment, which is a function of the resulting forces on the workpiece.
- the load capacity is significantly increased with this invention.
- the inner bridge is configured S-shaped.
- the invention is not limited to the S-shaped configuration of the bridge. All conceivable forms that lead to the goal of increasing the clamping force and load capacity are conceivable.
- the clamping jaw between the bridges have a cavity, wherein the curvatures of the cavity are designed to avoid overloading.
- the jaw below the inner bridge may have a curved slot to avoid overloading.
- the slot serves as security for overloading the clamping tool.
- the slot width is a geometric measure for the maximum allowable load.
- FIG. 1 a vise 2 with known in the art clamping jaws 11 and 12 shown in three-dimensional view.
- the jaw 11 is integral with the vise body 13 fixedly connected.
- holes 14 are provided for attachment in a conventional manner to a work table.
- the vise bed 15 is arranged on which the in FIG. 2 shown workpiece 6 is clamped.
- a spindle assembly 16 is installed inside the vise body 13.
- the spindle assembly 16 consists in a conventional manner of a spindle 22 which is secured on one side of the vice body 13 by means of a nut 17 and on the other side by a rotatable handle 18 for actuating the spindle 22 is completed.
- FIG. 2 shows the side view of a vise with an exemplary embodiment of the clamping jaws 1.
- a workpiece 6 is clamped.
- the reference numerals in FIG. 2 correspond to the reference numerals in FIG FIG. 1 ,
- FIG. 3 is a jaw 1, which is movably supported on a guide 23, shown in three-dimensional view.
- a possible embodiment of a clamping jaw 1 is the side view in FIG. 4 refer to.
- the clamping jaw 1 has a clamping plate 3 with the workpiece 6 facing surface 7. Further, in the clamping jaw 1, an outer and an inner bridge 4 and 5 are arranged. The course of the inner and outer bridge 4 and 5 is not parallel. The inner bridge 5 is more curved than the outer bridge 4 in order to achieve a lower rigidity. Due to the spring properties thus obtained, it is possible to achieve a full-surface contact of the surface 7 of the clamping plate 3 with the workpiece 6.
- the balance of power in the clamped state is in the FIGS. 5a and 5b described in more detail.
- the embodiment shown here shows an arcuately shaped outer bridge 4 and an S-shaped inner bridge 5.
- the cavity 8 enclosed by the bridges 4 and 5 is provided with such curvatures 9 that an overstressing of the clamping jaws is prevented. Furthermore, a curved, for example S-shaped slot 10 between the vise bed 15 and the inner bridge 5 is provided as overload protection. The gap width formed by the slot 10 becomes zero if the torque produced during clamping would become too high.
- FIGS. 5a and 5b A comparison of the balance of forces in the clamped state between a known jaw and an exemplary inventive clamping jaw show the FIGS. 5a and 5b .
- the FIG. 5a shows the situation according to the prior art.
- the two bridges 19 and 20 include as cavity 21 a parallelogram.
- the clamping force K is constant over the entire surface 24 of the clamping plane 25.
- the resulting force K r engages in the middle M of the clamping plane 25, so that a torque D m1 , formed from the resultant force K r and the distance L 1 results.
- the force flow in the invention is different, represented by the example in FIG. 5b , Due to the specially curved bridges 4 and 5, the clamping forces K decrease from top to bottom. The point of application of the resulting force K r is above the center M of the surface 7 of the clamping plate 3. Thus, the distance L 2 is greater than the distance L 1 in FIG. 5a , Consequently, the torque D m2 increases over the torque D m1 over the prior art. It is essential to achieve a maximum bending moment, which is multiplied by the forces K r and F 2 with the arm L 2 results. The workpiece is held in the critical bending direction by friction. The flexural strength is significantly dependent on the length L 2 .
- the invention is not limited to the curved shapes of the bridges and the slot shown in the figures. It is essential to find such a geometry, which results in a higher force in the direction of the vice bed compared to the prior art with straight and parallel geometric properties.
- the advantages associated with the invention are in particular to achieve a greater load capacity and a greater clamping force at the same operating torque by a suitable shape of the clamping jaws.
- the handling of the vise with the inventive jaws less resilient to their joints and muscles.

Abstract
Description
Die Erfindung betrifft eine Spannbacke für einen Schraubstock mit einer Spannplatte und mindestens zwei Brücken, gemäss des Oberbegriffes von Anspruch 1.The invention relates to a clamping jaw for a vice with a clamping plate and at least two bridges, according to the preamble of
Solchline Spannbache ist beispiels weise aus der
Zum genauen Bearbeiten eines Werkstückes, beispielsweise in einer Funkenerosionsmaschine, Werkzeugmaschine etc., ist es erforderlich, dass das Werkstück, welches bearbeitet werden soll, fest gegen das Schraubstockbett eingespannt ist. Es besteht jedoch die Möglichkeit, dass sich das Werkstück geringfügig beim Einspannen vom Schraubstockbett weg bewegt. Diese Unsicherheit kann zu Ungenauigkeiten führen.For accurate machining of a workpiece, for example in a spark erosion machine, machine tool, etc., it is necessary that the workpiece to be processed, is clamped firmly against the vise bed. However, there is the possibility that the workpiece will move slightly away from the vise bed during clamping. This uncertainty can lead to inaccuracies.

Eine Hauptforderung für ein optimales Spannsystem ist eine Einspannung eines Werkstückes, welches sich beim Einspannen und im eingespannten Zustand nicht von dem Schraubstockbett weg bewegen darf. Beispielsweise wird in Drahterosionsmaschinen während der Bearbeitung das Werkstück von fliessendem Wasser bis zu Drücken von 100 bar beaufschlagt, um Späne oder Abfallmaterial wegzuspülen. Dies kann zu Vibrationen des eingespannten Werkstückes führen, die sich auf die genaue Einspannung des Werkstückes negativ auswirken kann. Das Problem beim Stand der Technik ist, dass die geforderte Festigkeit beim Einspannen eines Werkzeuges aufgrund von anspruchsvolleren Anforderungen an die Anwendung nicht erreicht wird. Die Werkstücke werden beispielsweise grösser, so dass eine Einspannvorrichtung der vorliegenden Art die Fähigkeit haben muss, auch Werkstücke, die relativ gross zu der Grösse des Einspannwerkzeuges ist, optimal einspannen zu können. Beispielsweise haben Drahterosionmaschinen höhere Arbeitsgeschwindigkeiten. Dies erfordert höhere Wasserdrücke zum Abtransport der anfallenden Späne, was wiederum eine höhere Belastung auf das Werkstück zur Folge hat.A main requirement for an optimal clamping system is a clamping of a workpiece, which must not move away from the vise bed during clamping and in the clamped state. For example, in wire EDM machines, during machining, the workpiece becomes runny water up to pressures of 100 bar applied to rinse chips or waste material away. This can lead to vibrations of the clamped workpiece, which can negatively affect the exact clamping of the workpiece. The problem with the prior art is that the required strength when clamping a tool is not achieved due to more demanding application requirements. The workpieces become larger, for example, so that a clamping device of the present type must have the ability to optimally clamp workpieces that are relatively large to the size of the clamping tool. For example, wire erosion machines have higher working speeds. This requires higher water pressures for the removal of the resulting chips, which in turn has a higher load on the workpiece result.
Ein weiterer Nachteil ist der Einsatz von überstehenden Werkstücken aufgrund von zu geringer Belastungsmöglichkeit. Ein herausstehendes Werkstück erzeugt ein gewisses Biegemoment, welches die Einspannkraft negativ belasten kann.Another disadvantage is the use of protruding workpieces due to low load possibility. A protruding workpiece generates a certain bending moment, which can negatively burden the clamping force.
Für eine Bedienperson kann es von körperlichem Nachteil (Belastung der Gelenke und Muskeln) sein, wenn beispielsweise der Schraubstock mittels eines Schraubenschlüssels vielmals hintereinander manuell bedient werden muss.For an operator, it can be of physical disadvantage (stress on the joints and muscles), for example, if the vise must be manually operated by means of a wrench many times in succession.
Somit ist es die Aufgabe der Erfindung alle diese Nachteile zu vermeiden, nämlich die Einspannkraft bei gleicher Bedienkraft in Richtung Schraubstockbett und die Einspannfestigkeit zu vergrössern.Thus, it is the object of the invention to avoid all these disadvantages, namely to increase the clamping force with the same operating force towards the vise bed and the clamping strength.
Erfindungsgemäss wird die Erfindung durch das Kennzeichen von Anspruch 1 gelöst.According to the invention, the invention is solved by the characterizing part of
Durch die variable Spannkraft der Spannbacken wird eine Erhöhung des Drehmomentes erreicht, indem bevorzugt die resultierende Spannkraft oberhalb der Mitte der Oberfläche der Spannplatte liegt.Due to the variable clamping force of the clamping jaws, an increase in the torque is achieved by preferably the resulting clamping force is above the center of the surface of the clamping plate.
Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further embodiments of the invention will become apparent from the dependent claims.
Durch eine oder mehrerer dieser Massnahmen wird eine Verlagerung des Angriffspunktes der Spannkraft parallel zum Schraubstockbett erzielt mit der Folge einer Vergrösserung des Drehmomentes, welches auf das Werkstück wirkt. Infolgedessen wird die Festigkeit der Einspannung in Richtung senkrecht zum Schraubstockbett vergrössert. Das wesentliche Merkmal ist die Erreichung einer maximalen Belastbarkeit. Die Belastbarkeit ist durch das maximale Biegemoment gegeben, welches eine Funktion der resultierenden Kräfte auf das Werkstück ist. Die Belastbarkeit wird mit dieser Erfindung wesentlich vergrössert.By one or more of these measures, a displacement of the point of application of the clamping force is achieved in parallel to the vise bed with the result of an increase in the torque which acts on the workpiece. As a result, the strength of the clamping in the direction perpendicular to the vise bed is increased. The essential feature is the achievement of a maximum load capacity. The load capacity is given by the maximum bending moment, which is a function of the resulting forces on the workpiece. The load capacity is significantly increased with this invention.
Weiterhin wird das erforderliche Drehmoment, welches die Bedienperson aufwenden muss, verringert, um die gleiche Belastung wie nach dem Stand der Technik zu erzielen. Dies dient der Gesundheit der Bedienperson.Furthermore, the required torque which the operator must expend is reduced to achieve the same load as in the prior art. This is for the health of the operator.
Gemäss einer bevorzugten Ausführungsform ist die innere Brücke S-förmig ausgestaltet. Die Erfindung ist nicht auf die S-förmige Ausgestaltung der Brücke beschränkt. Alle denkbaren Formen, die zum Ziel einer Erhöhung der Spannkraft und Belastbarkeit führen sind denkbar.According to a preferred embodiment, the inner bridge is configured S-shaped. The invention is not limited to the S-shaped configuration of the bridge. All conceivable forms that lead to the goal of increasing the clamping force and load capacity are conceivable.
Erfindungsgemäss kann die Spannbacke zwischen den Brücken einen Hohlraum aufweisen, wobei die Krümmungen des Hohlraumes zur Vermeidung von Überbelastungen entsprechend ausgebildet sind.According to the invention, the clamping jaw between the bridges have a cavity, wherein the curvatures of the cavity are designed to avoid overloading.
Weiterhin kann die Spannbacke unterhalb der inneren Brücke einen gekrümmten Schlitz zur Vermeidung von Überbelastungen aufweisen.Furthermore, the jaw below the inner bridge may have a curved slot to avoid overloading.
Der Schlitz dient als Sicherheit für Überlastungen des Spannwerkzeuges. Die Schlitzbreite ist ein geometrisches Mass für die maximal erlaubte Belastung.The slot serves as security for overloading the clamping tool. The slot width is a geometric measure for the maximum allowable load.

For an operator, the handling of the vise with the inventive jaws less resilient to their joints and muscles.
