Description
Zwei- oder dreidimensionale Tragstruktur für eine Werkzeugmaschine, insbesondere eine Laserbearbeitungsmaschine,Two- or three-dimensional support structure for a machine tool, in particular a laser processing machine,
BESCHREIBUNGDESCRIPTION
Die Erfindung betrifft eine zwei- oder dreidimensionale Tragstruktur für eine Werkzeugmaschine, insbesondere eine Laserbearbeitungsmaschine, bestehend aus mehreren mit Hilfe von Aussparungen ineinander steckbaren ebenen Bauteilen wie Rippen oder Platten zur Ausbildung einer Art Gitterstruktur.The invention relates to a two- or three-dimensional support structure for a machine tool, in particular a laser processing machine, consisting of a plurality of flat components, such as ribs or plates, which can be plugged into one another with the aid of recesses to form a type of lattice structure.
Eine derartige Tragstruktur ist beispielsweise durch die DE 197 39 253 AI bekannt geworden.Such a support structure is known for example from DE 197 39 253 AI.
Dort ist eine Gitterstruktur in Leichtbauweise mit sich kreuzenden, ineinander gesteckten Streifen beschrieben, welche zur Steckverbindung geschlitzt ausgebildet sind.There is described a lattice structure in lightweight construction with intersecting strips inserted into one another, which are slotted for the plug connection.
Schalenstrukturen mit Versteifungsrippen können beispielsweise dem Buch "Faszination Blech", hrsg. von Trumpf GmbH + Co. KG, entnommen werden.Shell structures with stiffening ribs can be found, for example, in the book "Faszination Blech", ed. from Trumpf GmbH + Co. KG.
Bewegte Tragstrukturen von Werkzeugmaschinen oderMoving support structures of machine tools or
Laserbearbeitungsmaschinen sollen eine möglichst hohe Steifigkeit bei möglichst geringem Gewicht aufweisen, damit die Werkzeugmaschine oder Laserbearbeitungsmaschine der Forderung nach hoher Bahngenauigkeit bei hoher Dynamik gerecht werden kann.Laser processing machines should have the highest possible rigidity with the lowest possible weight, so that the machine tool or laser processing machine can meet the requirement for high path accuracy with high dynamics.
Bekannte Gitterstrukturen sind aufwändig zu fertigen, weil die ineinander zu steckenden Blechstreifen während des Aufbaus der Gitterstruktur noch nicht fixiert sind.
Bekannte Fixierungen wiederum erfordern Umformungen im Blech. Dies bedeutet zusätzliche Arbeitsschritte bei der Herstellung der Blechstreifen.Known lattice structures are complex to manufacture because the metal strips to be inserted into one another are not yet fixed during the construction of the lattice structure. Known fixings in turn require forming in the sheet. This means additional work steps in the production of the metal strips.
Eine weitere Verbesserung der Bahngenauigkeit durch Gewichtsreduzierung einerseits und durch Steifigkeitserhöhung anderseits sowie eine gleichzeitige Erleichterung der Fertigung der Tragstruktur hat sich der Anmelder zur Aufgabe gemacht.The applicant has set itself the task of further improving the path accuracy by reducing the weight on the one hand and increasing the stiffness on the other hand and simultaneously simplifying the manufacture of the supporting structure.
Diese Aufgabe wird durch eine Tragstruktur mit mehreren mit Hilfe von Aussparungen ineinander steckbaren ebenen Bauteilen gelöst, von denen vorzugsweise drei zumindest an einem Punkt der Tragstruktur unter Ausbildung einer Verrastung ineinander gesteckt sind. Die erfindungsgemäßen Bauteile können aus ebenen Metallblechen geringer Dicke (< 2 mm) mit Hilfe eines Lasers geschnitten werden. Durch die Verrastung sind die Bauteile von Beginn des Aufbaus der Gitterstruktur an fixiert. Eine dauerhafte zusätzliche Fixierung ist voraussichtlich nur in geringem Maße erforderlich und kann vorzugsweise durch einen Klebstoff - also kalt - bzw. alternativ laserverschweißt mittels automatisierbarer Verfahren erfolgen, wodurch eine geringe thermische Belastung der Bauteile der Tragstruktur während des Aufbaus der Tragstruktur eintritt.This object is achieved by a support structure having a plurality of planar components which can be plugged into one another with the aid of cutouts, of which three are preferably plugged into one another at least at one point of the support structure with the formation of a catch. The components according to the invention can be cut from flat metal sheets of small thickness (<2 mm) with the aid of a laser. The components are fixed in place from the start of the construction of the lattice structure. A permanent additional fixation is likely to be required only to a small extent and can preferably be carried out by means of an adhesive - that is to say cold - or alternatively laser-welded by means of automated processes, as a result of which a low thermal load on the components of the support structure occurs during the construction of the support structure.
Bevorzugt ist, dass das eine Bauteil eine Rastnase oder einen Rastfinger und das andere Bauteil eine Aussparung zum Einfallen der Rastnase aufweist. Dies bedeutet eine einfach zu fertigende Verrastung der Bauteile, weil derartige Rastnasen oder Rastfinger beispielsweise durch einen Freischnitt aus ebenem Metallblech mit Hilfe des Lasers leicht zu fertigen sind.It is preferred that one component has a locking lug or a locking finger and the other component has a recess for engaging the locking lug. This means that the components can be latched in an easy manner because such latching lugs or latching fingers can be easily manufactured, for example, by means of a cut out of a flat metal sheet with the aid of the laser.
Eine symmetrische, hoch belastbare Tragstruktur mit hexagonal angeordneten Rippen wird erreicht, wenn sich jeweils zwei der Bauteile an
einer Seitenfläche der Tragstruktur unter Ausbildung von Winkeln c- = 60° kreuzen.A symmetrical, highly resilient support structure with hexagonally arranged ribs is achieved when two of the components are in contact cross one side of the support structure to form angles c = 60 °.
Die Realisierung der Steckverbindung dreier Bauteile kann dadurch erreicht werden, dass ein erstes Bauteil eine quer zur Längsrichtung verlaufende Aussparung, dass ein zweites Bauteil zwei voneinander beabstandete, durch einen Steg getrennte, quer zur Längsrichtung verlaufende Aussparungen und dass ein drittes Bauteil eine quer zur Längsrichtung verlaufende Aussparung aufweist.The implementation of the plug connection of three components can be achieved in that a first component has a recess running transversely to the longitudinal direction, a second component has two recesses spaced apart from one another by a web and running transversely to the longitudinal direction, and that a third component has a cross-section running longitudinally Has recess.
Im Bereich der freien Enden oder Ecken können die Bauteile Ausnehmungen oder Ausschnitte aufweisen, um überstehende Ecken oder Kanten zu vermeiden.In the area of the free ends or corners, the components can have recesses or cutouts in order to avoid protruding corners or edges.
Zur Herstellung einer dreidimensionalen Tragstruktur können neben ebenen Rippen erfindungsgemäß auch Platten verwendet werden, beispielsweise ein Aufbau aus verschiedenen Rippen und zwei Abschlussplatten.To produce a three-dimensional support structure, in addition to flat ribs, plates can also be used according to the invention, for example a structure made up of different ribs and two end plates.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird nachfolgend mit Bezug zu den Figuren der Zeichnung näher erläutert. Es zeigt:An embodiment of the invention is shown schematically in the drawing and is explained in more detail below with reference to the figures of the drawing. It shows:

Aus der Fig. 1 ist der Aufbau einer ebenen, aus einem ca. 1 mm dicken Stahlblech gefertigten, ersten Rippe 1 ersichtlich. Die erste Rippe 1 weist an ihren freien Enden 2 und 3 Aussparungen 4a und 5a, welche quer zur Längsrichtung der ersten Rippe 1 verlaufen, und weitere Aussparungen 4b und 5b auf. Zusätzlich ist eine weitere Aussparung 6 in der Mitte zwischen den beiden anderen Aussparungen 4a, 4b und 5a, 5b ausgebildet. Die erste Rippe 1 weist eine geradlinige Kontur an der einen Längsseite 7 auf, welche der Außenseite eines später aus mehreren ineinander gesteckten Rippen ausgebildeten ebenen oder dreidimensionalen Profilkörpers zugeordnet ist.1 shows the structure of a flat, first rib 1 made from an approximately 1 mm thick steel sheet. The first rib 1 has at its free ends 2 and 3 cutouts 4a and 5a, which run transversely to the longitudinal direction of the first rib 1, and further cutouts 4b and 5b. In addition, a further recess 6 is formed in the middle between the two other recesses 4a, 4b and 5a, 5b. The first rib 1 has a rectilinear contour on one longitudinal side 7, which is assigned to the outside of a flat or three-dimensional profile body which is later formed from a plurality of ribs which are inserted into one another.
Die Außenseite kann zusätzlich mit einer Verkleidung überzogen sein, damit die eigentliche Tragstruktur nicht erkennbar und kaschiert ist und eine Steifigkeitserhöhung zustande kommt. Die andere Längsseite 8 weist teilweise eine bogenförmige Kontur auf, um zwischen beiden freien Enden 2 und 3, welche mehr Material zur Ausbildung und Verstärkung der Ausnehmungen 4a und 5a benötigen, Material einzusparen. Dies trägt zur Leichtbauweise bei. Eine Ausnehmung 9 wird später einem Rand- oder Eckbereich eines gebildeten Profilkörpers zugeordnet, damit Vollmaterial zur Erhöhung des Trägkeitsmoments und Möglichkeiten zur Montage gegeben sind.The outside can also be covered with a cladding so that the actual supporting structure is not recognizable and concealed and an increase in rigidity is achieved. The other long side 8 partially has an arcuate contour in order to save material between the two free ends 2 and 3, which require more material to form and reinforce the recesses 4a and 5a. This contributes to the lightweight construction. A recess 9 is later assigned to an edge or corner area of a formed profile body, so that solid material to increase the moment of inertia and possibilities for assembly are given.
Fig. 2 veranschaulicht den Aufbau einer ebenen zweiten Rippe 10. ImFig. 2 illustrates the structure of a flat second rib 10. Im
Unterschied zur ersten Rippe 1 besitzt die zweite Rippe 10 im Bereich von Aussparungen 11, 12 und 13 frei geschnittene Rastnasen 14, welche durch den Freischnitt elastisch verformt werden können, wenn eine erste Rippe
über eine Aussparung mit der zweiten Rippe zusammengesteckt wird. Dabei wird die Rastnase quer zur Längsrichtung der jeweiligen Aussparung federnd ausgelenkt (siehe in der Fig. 3: Doppelpfeil 15). Das Ineinanderstecken erfolgt durch das Zusammenwirken der Aussparungen 4a und 5a einerseits bzw. der Aussparungen 11, 12 bzw. 13 andererseits. Durch das Einrasten der Rastnase 14 in die Aussparung 4b oder 5b kommt es zu einer Arretierung, welche eine stabile Verbindung schafft. Aussparungen und Kontur der zweiten Rippe 10 dienen im Wesentlichen denselben Anforderungen wie die der ersten Rippe. Ebenso ist auch die zweite Rippe 10 aus einem dünnen Stahlblech gefertigt.In contrast to the first rib 1, the second rib 10 has freely cut latching lugs 14 in the region of cutouts 11, 12 and 13, which can be elastically deformed by the free cut if a first rib is plugged together with the second rib via a recess. The latch is deflected resiliently transversely to the longitudinal direction of the respective recess (see in FIG. 3: double arrow 15). The interlocking takes place through the interaction of the recesses 4a and 5a on the one hand and the recesses 11, 12 and 13 on the other. By latching the locking lug 14 into the recess 4b or 5b, there is a locking which creates a stable connection. Recesses and contour of the second rib 10 serve essentially the same requirements as those of the first rib. Likewise, the second rib 10 is also made from a thin steel sheet.
Fig. 4 demonstriert, dass eine Rippe nur eine Möglichkeit eines Elements der erfindungsgemäßen Tragstruktur darstellt. Die bereits erwähnten Aussparungen, Federnasen und Konturen können an Rippen oder Platten beliebiger Form ausgebildet sein. Die Anzahl der Aussparungen richtet sich nach der Größe des später zu bildenden ebenen oder dreidimensionalen Körpers. So zeigt Fig. 4 eine Abschlussplatte 16 aus dünnem Stahlblech für die Stirnseiten einer Tragstruktur oder eines Trägers, wobei in die Aussparungen 17 erste Rippen über deren Aussparungen eingesteckt werden können. Die nach außen gerichtete Seite 18 ist gerade ausgebildet, während die nach innen gerichtete Seite 19 der Abschlussplatte 16 bogenförmige Abschnitte zur Material- und Gewichteinsparung besitzt. Lediglich dort, wo Aussparungen zum Ineinanderstecken von Rippen vorgesehen sind, ist ein nach innen hin größerer Materialstreifen 21 ausgebildet. Rastnasen 20 gewährleisten die sichere Fixierung der ineinander gesteckten Rippen mit Hilfe der bereits erwähnten Verrastung. Mit Bezugszeichen 30a, 30b und 30c (siehe auch Fig. 5) sind diejenigen Längsseiten der Rippen bezeichnet, welche später der Außenseite der Tragstruktur zugeordnet sind.
Fig. 5 zeigt das Ineinanderstecken von ersten, zweiten und dritten Rippen zu einer ebenen Tragstruktur 22, von der ein Ausschnitt dargestellt ist. Rippen 23, 24, 25 kreuzen jeweils einander unter Ausbildung eines 60° Winkels , sodass eine Gitterstruktur gleichwinkliger Dreiecke bzw. Rauten entsteht. Vier derartige Gitterstrukturen als Seitenwände ergeben zusammen mit an den Stirnseiten angeordneten Abschlussplatten 16 (siehe Fig. 3) einen dreidimensionalen Träger. Aus dem Teilausschnitt gemäß Fig. 5 kann gefolgert werden, dass durch diese Gitterstruktur Gitterflächen beliebiger Fläche erzeugt werden können.4 demonstrates that a rib represents only one possibility of an element of the supporting structure according to the invention. The recesses, spring lugs and contours already mentioned can be formed on ribs or plates of any shape. The number of recesses depends on the size of the flat or three-dimensional body to be formed later. 4 shows an end plate 16 made of thin sheet steel for the end faces of a support structure or a carrier, it being possible for first ribs to be inserted into the recesses 17 via their recesses. The outward side 18 is straight, while the inward side 19 of the end plate 16 has arcuate sections for saving material and weight. A material strip 21 which is larger towards the inside is formed only where recesses are provided for inserting ribs into one another. Locking lugs 20 ensure the secure fixation of the inserted ribs with the aid of the already mentioned locking. Reference numerals 30a, 30b and 30c (see also FIG. 5) denote those longitudinal sides of the ribs which are later assigned to the outside of the support structure. FIG. 5 shows the insertion of the first, second and third ribs into a flat support structure 22, a section of which is shown. Ribs 23, 24, 25 cross each other to form a 60 ° angle, so that a lattice structure of equiangular triangles or diamonds is formed. Four such lattice structures as side walls together with end plates 16 arranged on the end faces (see FIG. 3) form a three-dimensional support. It can be concluded from the partial section according to FIG. 5 that lattice surfaces of any surface can be generated by this lattice structure.
Gemäß Fig. 6 erfolgt das Ineinanderstecken der Rippen 23, 24 und 25 an einem Kreuzungspunkt VI (siehe Fig. 5) mit Hilfe der Aussparungen 26a, 27 und 28 in Richtung der eingezeichneten Pfeile. Die Rastnase 31 kann in die Aussparung 26b einrasten und für eine Arretierung der zusammengesteckten Teile sorgen. Die Steckverbindung mit Verriegelung durch diese drei Rippen 23 bis 25 verleiht der Tragstruktur 22 ihre wesentliche Stabilität, weil die mittlere Rippe 24 durch die beiden anderen Rippen 23 und 25 gehalten und verriegelt werden kann.According to FIG. 6, the ribs 23, 24 and 25 are inserted into one another at a crossing point VI (see FIG. 5) with the aid of the cutouts 26a, 27 and 28 in the direction of the arrows shown. The locking lug 31 can snap into the recess 26b and ensure that the parts plugged together are locked. The plug connection with locking by means of these three ribs 23 to 25 gives the support structure 22 its essential stability because the central rib 24 can be held and locked by the other two ribs 23 and 25.
Gemäß Fig. 7 erfolgt das Ineinanderstecken der Rippen 23 und 25 an einem weiteren Kreuzungspunkt VII (siehe Fig. 5) mit Hilfe der Aussparungen 32 und 33 ohne Verrastung.
According to FIG. 7, the ribs 23 and 25 are inserted into one another at a further crossing point VII (see FIG. 5) with the aid of the cutouts 32 and 33 without latching.
