Definitions
- the invention relates to a positioning device for workpieces with the features of the preamble of independent claim 1.
- a positioning device for workpieces in which a three-dimensionally deformable workpiece abutment surface is formed by the front ends of juxtaposed in two directions, mutually parallel plungers, which are pressed against elastic forces, is already out of US-A-2,754,708 known.
- the elastic return forces are provided on the plunger by coil springs which are arranged on a rear, reduced in diameter end of the respective plunger and on the one hand supported on a shoulder of the plunger and on the other hand on a perforated plate through which the reduced diameter rear ends Pass the plunger and where the plunger are secured.
- the cost of producing such a positioning device is high.
- the depth of the positioning device in the main direction of extension of the plunger is also high, because the projecting beyond the perforated plate to the rear part of each plunger is taken into account.
- a positioning device having the features of the preamble of independent claim 1 is known from DE 297 13 815 U1 known.
- the juxtaposed plunger are not supported by individual coil springs but by a common pressure pad.
- the plunger are held by a perforated plate here, but through the here reduced in diameter diameter front ends of the plunger to step.

- the from the DE 297 13 815 U1 known positioning device is provided in particular for the formation of transport pallets for workpieces. Although it has a comparatively simple structure. However, it is also associated with disadvantages in that the common for all plunger pressure pad for adjacent plunger provides no independent restoring forces. If a plunger is pressed more strongly than its adjacent plunger, this reduces the restoring force on the adjacent plunger him considerably, as far as the restoring force is not completely lost to these plunger over a certain Eindgurweg.
- the invention has for its object to provide a positioning device with the features of the preamble of independent claim 1, which indeed have a very simple structure, but still provides a restoring force for each of the plunger, which as independent as possible of the degree of depression of the adjacent plunger is.

- the individual support areas of the support cushion of the new positioning device can be formed from a solid block of elastic material.
- the cuts can begin at the front of the Abstützkissens and end within the Abstützkissens so that it remains solid on its back, that is not severed by the cuts.
- the separate support areas can also extend to the back of the pressure pad.
- support regions which extend from one another to the back of the pressure pad they can be glued to the back of the pressure pad on a common carrier material or otherwise connected to one another for easier joint handling.
- a loop band can be applied to the back of the pressure pad, with which the individual mutually separate support areas can then beANCklettet on a hook tape.
- the support areas can also be juxtaposed sections of an extruded strand of elastic material.
- extruded sections can provide the favorable smoothly closed surfaces for the support areas from the outset.
- the sections of the extruded strand may also be interconnected in an area adjacent the back of the support pad. You can, for example, be potted there with a matrix material.
- the Abstützkissen in the new positioning preferably consists of a foam. It is important in the selection of concrete foam that it is possible permanently elastic and also the other requirements for the positioning device, such as temperature resistance, oil resistance, electrical resistance or the like. Fair.

- the formation of the ram of a fiber composite material is possible.
- the plunger are glued with their backs to the pressure pad, ie their respective support region of the pressure pad, and the support areas of the pressure pad are in turn fixed on its back, can be dispensed with in the new positioning on a perforated plate for retaining the individual plunger ,
- a perforated plate can also be useful in the new positioning device.
- the plungers Preferably, in a friction region in which they are fixed to one another by the lateral frictional engagement, the plungers have equally large circular cross sections and are arranged in a densest two-dimensional packing within a laterally surrounding frame on which a clamping element for the plungers is supported.
- positioning device 1 has a plurality of plungers 2, which are aligned parallel to each other with respect to their coinciding with their main directions of extension axes.
- the plunger 2 are arranged side by side in two directions, of which one direction falls in the plane of the drawing and the other direction is perpendicular thereto.
- the juxtaposition of the plungers in two directions does not mean that they must be arranged in mutually orthogonal rows and columns. Rather, a densest two-dimensional packing of the circular plunger 2 in its cross-section is preferred.
- Each plunger 2 has a region 5 adjoining its front end 4 in which it has a reduced diameter compared with a friction region 6 adjoining at the rear.
- each of the plunger 2 is pressed against an elastic restoring force of a pressure pad 8, wherein the pressure pad 8 for each plunger 2 has a separate support region 9 on its front side facing the plungers. In its rear region, where the support cushion 8 is supported on a support plate 10, the support cushion 8, however, is continuously formed over the areas of all plunger 2 away.
- the support areas 9 of the support pad 8 can be compressed independently of each other, ie when pressing one of the plunger 2, the restoring force on the adjacent plunger 2 is not lost.

Description
Die Erfindung bezieht sich auf eine Positioniervorrichtung für Werkstücke mit den Merkmalen des Oberbegriffs des unabhängigen Patentanspruchs 1.The invention relates to a positioning device for workpieces with the features of the preamble of
Eine Positioniervorrichtung für Werkstücke, bei der eine dreidimensional verformbare Werkstückanlagefläche durch die vorderen Enden von in zwei Richtungen nebeneinander angeordneten, parallel zueinander angeordneten Stößeln, die gegen elastische Kräfte eindrückbar sind, ausgebildet ist, ist bereits aus der
Eine Positioniervorrichtung mit den Merkmalen des Oberbegriffs des unabhängigen Patentanspruchs 1 ist aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Positioniervorrichtung mit den Merkmalen des Oberbegriffs des unabhängigen Patentanspruchs 1 aufzuzeigen, die zwar einen sehr einfachen Aufbau aufweisen, aber dennoch für jeden der Stößel eine Rückstellkraft bereitstellt, welche von dem Maß des Eindrückens der ihm benachbarten Stößel möglichst unabhängig ist.The invention has for its object to provide a positioning device with the features of the preamble of
Erfindungsgemäß wird diese Aufgabe durch eine Positioniervorrichtung mit den Merkmalen des unabhängigen Patentanspruchs 1 gelöst. Bevorzugte Ausführungsformen der neuen Positioniervorrichtung sind in den abhängigen Patentansprüchen 2 bis 13 definiert.According to the invention, this object is achieved by a positioning device having the features of
Bei der neuen Positioniervorrichtung ist das Druckkissen, an dem sich die Stößel abstützen, nicht als durchgängiger Block vorgesehen, sondern zumindest an seiner den Stößeln zugekehrten Vorderseite parallel zu den Stößeln im Raster der Stößel unterteilt. D. h, das Druckkissen weist an seiner den Stößeln zugekehrten Vorderseite für jeden einzelnen Stößel einen eigenen Abstützbereich auf, in dem das Druckkissen von dem jeweiligen Stößel eingedrückt werden kann, ohne dass dieser Stößel dabei zwangsläufig auch die Abstützbereiche der an den angrenzenden Stößel in seiner Eindrückrichtung mitnimmt. Dabei ist zwar ein Einfluss eines Abstützbereichs eines Stößels auf die Abstützbereiche der ihm benachbarten Stößel nicht ausgeschlossen, weil das Druckkissen eine Neigung aufweisen kann, sich beim Zusammendrücken in der Eindrückrichtung der Stößel seitlich auszudehnen. Die hieraus resultierenden Einwirkungen auf die benachbarten Abstützbereich sind vielfach jedoch unbeachtlich und sie können durch verschiedene Maßnahmen gezielt begrenzt werden.In the new positioning device, the pressure pad on which the plunger support, not provided as a continuous block, but divided at least on its front side facing the plungers parallel to the plungers in the grid of the plunger. D. h, the pressure pad has on its front side facing the ram for each ram its own support area in which the pressure pad can be pressed by the respective plunger without this plunger thereby inevitably the Abstützbereiche entrains the adjacent plunger in its Eindrückrichtung. Although an influence of a support area of a plunger on the support areas of the adjacent plunger is not excluded, because the pressure pad may have a tendency to expand laterally when compressed in the Eindrückrichtung the plunger. However, the resulting effects on the adjacent support area are often irrelevant and they can be selectively limited by various measures.
Zu diesen Maßnahmen zählt die Verwendung eines Materials für das Druckkissen, das eine möglichst geringe Expansion quer zu der Druckrichtung aufweist. Weiterhin können seitliche Freiräume zwischen den Abstützbereichen vorgesehen werden, die bei unbelastetem Abstützkissen vorliegen und in die die Abstützbereiche unter Druckbelastung in Querrichtung expandieren können, ohne die ihnen benachbarten Abstützbereiche unmittelbar zu beeinflussen. Im unbelasteten Zustand des Abstützkissens ist es unter diesem Gesichtspunkt günstig, wenn die Abstützbereiche untereinander umlaufend seitlich beabstandet sind, d. h. keinerlei Kontaktbereiche sondern freie Abstände zueinander aufweisen.These measures include the use of a material for the pressure pad, which has the least possible expansion transverse to the printing direction. Furthermore, lateral clearances between the support areas can be provided, which are present in unloaded Abstützkissen and in which the support areas can expand under pressure in the transverse direction, without directly affecting the adjacent support areas. In the unloaded state of the Abstützkissens it is favorable from this point of view, when the support areas are circumferentially spaced from each other laterally, d. H. have no contact areas but free distances to each other.
In einer besonders bevorzugten Ausführungsform weisen die Abstützbereiche bei unbelastetem Abstützkissen eine zur Mitte ihrer Längserstreckung zunehmende Durchmesserverjüngung auf, die ihre Expansion in Querrichtung unter Druckbelastung so vorweg nimmt, dass die Abstützbereiche auch unter maximaler Druckbelastung einen bestimmten maximalen Durchmesser nicht überschreiten uns sich so auch unter maximaler Druckbelastung gegenseitig nicht beeinträchtigen.In a particularly preferred embodiment, the support areas at unloaded Abstützkissen increasing to the middle of its longitudinal extension diameter taper, which anticipates their expansion in the transverse direction under pressure so that the support areas do not exceed a maximum maximum diameter even under maximum pressure load us so also at maximum Pressure load does not affect each other.
Als alternative oder zusätzliche Maßnahme ist es möglich, die einander zugewandten Seitenflächen der Abstützbereiche glatt geschlossen auszubilden oder mit einem Gleitmittel zu beschichten, um auch bei seitlich aneinander anliegenden Abstützbereichen ein möglichst reibungsloses aneinander Abgleiten in der Einrückrichtung der Stößel zu gewährleisten.As an alternative or additional measure, it is possible for the mutually facing side surfaces of the support areas to form smoothly closed or coated with a lubricant in order to ensure the smoothest possible sliding against each other in the direction of engagement of the plunger, even with laterally abutting support areas.
Die einzelnen Abstützbereiche des Abstützkissens der neuen Positioniervorrichtung können aus einem massiven Block aus elastischem Material ausgebildet sein. Dabei können die Schnitte an der Vorderseite des Abstützkissens beginnen und innerhalb des Abstützkissens enden, so dass dieses an seiner Rückseite massiv bleibt, d. h. durch die Schnitte nicht durchtrennt ist. Die voneinander getrennten Abstützbereiche können jedoch auch bis an die Rückseite des Druckkissens reichen. In diesem Fall ist es möglich, die Abstützbereiche mit Schneidmitteln auszubilden, deren Schnitte nicht frei in den Druckkissen enden können, wie beispielsweise Wasserstrahlen. Bei bis an die Rückseite des Druckkissens reichenden voneinander getrennten Abstützbereichen können diese an der Rückseite des Druckkissens auf ein gemeinsames Trägermaterial aufgeklebt oder anderweitig zur leichteren gemeinsamen Handhabung miteinander verbunden sein. Hierzu kann an der Rückseite des Druckkissens auch beispielsweise ein Schlaufenband aufgebracht sein, mit dem die einzelnen voneinander getrennten Abstützbereiche dann auf ein Hakenband aufgeklettet werden können.The individual support areas of the support cushion of the new positioning device can be formed from a solid block of elastic material. The cuts can begin at the front of the Abstützkissens and end within the Abstützkissens so that it remains solid on its back, that is not severed by the cuts. However, the separate support areas can also extend to the back of the pressure pad. In this case, it is possible to use the support areas with cutting means form whose cuts can not end freely in the pressure pad, such as water jets. In the case of support regions which extend from one another to the back of the pressure pad, they can be glued to the back of the pressure pad on a common carrier material or otherwise connected to one another for easier joint handling. For this purpose, for example, a loop band can be applied to the back of the pressure pad, with which the individual mutually separate support areas can then be aufgeklettet on a hook tape.
Alternativ zum Ausschneiden der Abstützbereiche aus einem massiven Block können die Abstützbereiche auch nebeneinander angeordnete Abschnitte eines extrudierten Strangs aus elastischem Material sein. Derartige extrudierte Abschnitte können von vornherein die günstigen glatt geschlossenen Oberflächen für die Abstützbereiche bereitstellen. Die Abschnitte des extrudierten Strangs können ebenfalls in einem an die Rückseite des Abstützkissens angrenzenden Bereich miteinander verbunden sein. Sie können dort beispielsweise mit einem Matrixmaterial vergossen sein.As an alternative to cutting out the support areas from a solid block, the support areas can also be juxtaposed sections of an extruded strand of elastic material. Such extruded sections can provide the favorable smoothly closed surfaces for the support areas from the outset. The sections of the extruded strand may also be interconnected in an area adjacent the back of the support pad. You can, for example, be potted there with a matrix material.
Unabhängig von der konkreten Ausbildung der Abstützbereiche besteht das Abstützkissen bei der neuen Positioniervorrichtung vorzugsweise aus einem Schaumstoff. Es ist bei der Auswahl des konkreten Schaumstoffs darauf zu achten, dass dieser möglichst dauerelastisch ist und auch den anderen Anforderungen an die Positioniervorrichtung, wie beispielsweise Temperaturbeständigkeit, Ölbeständigkeit, elektrischer Widerstand oder dgl. gerecht wird.Regardless of the concrete design of the support areas, the Abstützkissen in the new positioning preferably consists of a foam. It is important in the selection of concrete foam that it is possible permanently elastic and also the other requirements for the positioning device, such as temperature resistance, oil resistance, electrical resistance or the like. Fair.
Die Stößel der neuen Positioniervorrichtung können zur Gewichts- und/oder Kostenersparnis statt aus Metall auch aus einem Kunststoff ausgebildet sein bzw. einen Grundkörper aus einem Kunststoff aufweisen, dessen vorderes Ende auch durch eine Metallkappe oder dgl. verstärkt sein kann. Auch die Ausbildung der Stößel aus einem Faserverbundwerkstoff ist möglich.The plunger of the new positioning device can also be made of a plastic instead of metal for weight and / or cost savings or have a base body made of a plastic whose front end can also be reinforced by a metal cap or the like. The formation of the ram of a fiber composite material is possible.
Wenn bei der neuen Positioniervorrichtung die Stößel mit ihren Rückseiten an das Druckkissen, d. h. ihrem jeweiligen Abstützbereich des Druckkissens angeklebt sind, und die Abstützbereiche des Druckkissens ihrerseits an ihrer Rückseite fixiert sind, kann bei der neuen Positioniervorrichtung auf einen Lochplatte zum Zurückhalten der einzelnen Stößel verzichtet werden. Aus Abdichtgründen des Bereichs, in dem die Stößel durch seitlichen Reibschluss fixierbar sind, kann eine derartige Lochplatte aber auch bei der neuen Positioniervorrichtung sinnvoll sein.If in the new positioning the plunger are glued with their backs to the pressure pad, ie their respective support region of the pressure pad, and the support areas of the pressure pad are in turn fixed on its back, can be dispensed with in the new positioning on a perforated plate for retaining the individual plunger , For sealing reasons of the area in which the plungers can be fixed by lateral frictional engagement, such a perforated plate can also be useful in the new positioning device.
Vorzugsweise weisen die Stößel in einem Reibbereich, in dem sie durch den seitlichen Reibschluss aneinander fixiert werden, gleich große kreisrunde Querschnitte auf und sind in einer dichtesten zweidimensionalen Packung innerhalb eines seitlich umlaufenden Rahmens angeordnet, an dem sich ein Spannelement für die Stößel abstützt.Preferably, in a friction region in which they are fixed to one another by the lateral frictional engagement, the plungers have equally large circular cross sections and are arranged in a densest two-dimensional packing within a laterally surrounding frame on which a clamping element for the plungers is supported.
