Aufgabe der Erfindung ist es, eine Bauteilverbindung bzw. ein Verfahren zum Herstellen einer Bauteilverbindung zu schaffen, die bzw. das auch bei kleinen Stückzahlen relativ kostengünstig ist.The object of the invention is to provide a component connection or a method for producing a component connection, which is relatively inexpensive even in small quantities.

Diese Aufgabe wird durch die Merkmale der Patentansprüche 1 bzw. 2 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.This object is solved by the features of claims 1 and 2, respectively. Advantageous embodiments and further developments of the invention can be found in the dependent claims.

Ausgangspunkt der Erfindung ist eine Bauteilverbindung mit einem ersten Bauteil, von dem ein ”männliches” Fixierelement absteht, und einem zweiten Bauteil, welches ein mit dem männlichen Fixierelement zusammenwirkendes ”weibliches” Fixierelement aufweist. Die beiden Bauteile werden über die beiden Fixierelemente miteinander verbunden bzw. relativ zueinander fixiert oder für eine anschließende zusätzliche bzw. dauerhaft feste Verbindung relativ zueinander vorfixiert. Das weibliche Fixierelement übergreift und/oder umgreift und/oder hintergreift das männliche Fixierelement, wodurch die beiden Bauteile formschlüssig und/oder reibschlüssig miteinander verbunden werden. Das Verbinden der beiden Bauteile bzw. ein relatives Vorfixieren der Bauteile zueinander kann durch bloßes Zusammenstecken bzw. Zusammenklipsen der Fixierelemente erfolgen.The starting point of the invention is a component connection with a first component, from which a "male" fixing element projects, and a second component, which has a "female" fixing element cooperating with the male fixing element. The two components are connected to each other via the two fixing elements or fixed relative to each other or prefixed for a subsequent additional or permanently fixed connection relative to each other. The female fixing element engages over and / or surrounds and / or engages behind the male fixing element, whereby the two components are positively connected and / or frictionally engaged with each other. The joining of the two components or a relative prefixing of the components to one another can be effected merely by plugging or clipping together the fixing elements.

Der Kern der Erfindung besteht darin, dass das weibliche Fixierelement und/oder das männliche Fixierelement „schichtweise” aufgebaut sind bzw. werden.The gist of the invention is that the female fixation element and / or the male fixation element are constructed "in layers".

Als geeignete Verfahren zum schichtweisen Aufbau eines weiblichen Fixierelements bzw. eines männlichen Fixierelements kommt z. B. Laserauftragschweißen, Lasersintern in Betracht. Derartige Verfahren sind auch unter dem Begriff „Rapid Prototyping” bekannt.As a suitable method for the layered structure of a female fixation element or a male fixation z. As laser cladding, laser sintering into consideration. Such methods are also known by the term "rapid prototyping".

Das weibliche bzw. das männliche Fixierelement können z. B. schichtweise aus einem Pulver aufgebaut werden, derart, dass eine Pulverschicht aufgebracht und durch Bestrahlen mit einem Laser verfestigt und mit dem darunter befindlichen Bauteil bzw. der darunter befindlichen Schicht verbunden wird. Nach dem Verfestigen der Schicht kann eine weitere Schicht aufgebracht und durch Bestrahlen mit einem Laser verfestigt werden, bis das weibliche bzw. das männliche Fixierelement entstanden ist.The female or the male fixation can z. B. layered from a powder, such that a powder layer is applied and solidified by irradiation with a laser and connected to the underlying component or the underlying layer. After solidification of the layer, a further layer can be applied and solidified by irradiation with a laser until the female or the male fixing element is formed.

Derartige schichtweise aufgebaute Fixierelemente kommen, wie bereits erwähnt, insbesondere für kleine Stückzahlen bzw. Kleinserienanwendungen, Prototypenbauteile etc. in Betracht. Mit solchen Verfahren können Bauteile mit nahezu beliebig komplexer Geometrie aufgebaut werden.Such layered fixation come, as already mentioned, in particular for small numbers or small series applications, prototype components, etc. into consideration. With such methods, components can be constructed with almost any complex geometry.

Für die schichtweise Herstellung der Fixierelemente kann z. B. ein metallhaltiges Pulver verwendet werden. Alternativ dazu können die Fixierelemente auch schichtweise aus einem Kunststoffpulver erzeugt werden.For the layered preparation of the fixing z. B. a metal-containing powder can be used. Alternatively, the fixing elements can also be produced in layers of a plastic powder.

Das erste und/oder das zweite Bauteil können z. B. aus einem Metallwerkstoff (z. B. Blech) oder aus einem Kunststoffmaterial (z. B. einem faserverstärkten Kunststoffmaterial) hergestellt sein bzw. werden.The first and / or the second component may, for. B. from a metal material (eg., Sheet metal) or from a plastic material (eg., A fiber-reinforced plastic material) to be made or become.

Nach einer Weiterbildung der Erfindung kann vorgesehen sein, dass die beiden Bauteile durch das männliche und das weibliche Fixierelement zunächst lediglich relativ zueinander positioniert und vorfixiert werden und anschließend dauerhaft fest miteinander verbunden werden, z. B. durch Verschweißen, Verkleben, Verschrauben, Vernieten oder durch andere dauerhaft feste Verbindungsverfahren.According to a development of the invention can be provided that the two components are initially positioned and prefixed by the male and female fixing only relative to each other and then permanently connected firmly together, z. B. by welding, gluing, screwing, riveting or by other permanently solid bonding methods.

Als Geometrie für das männliche Fixierelement kommt insbesondere eine ganz oder teilweise kugelförmige oder eine ganz oder teilweise ähnliche Geometrie in Betracht. Eine derartige Geometrie hat den Vorteil, dass beim Zusammenstecken der Fixierelemente Verkantungsprobleme weitgehend ausgeschlossen werden.In particular, a completely or partially spherical or completely or partially similar geometry comes into consideration as the geometry for the male fixing element. Such a geometry has the advantage that tilting problems are largely excluded when plugging the fixing.

Das weibliche Fixierelement kann durch mehrere einzelne Elemente gebildet sein. Beispielsweise kann das weibliche Fixierelement durch mehrere im Wesentlichen entlang eines Kreises auf dem zweiten Bauteil angeordnete, in Umfangsrichtung des Kreises voneinander beabstandete, von dem zweiten Bauteil kragenartig abstehende, federartige Elemente gebildet sein.The female fixation element may be formed by a plurality of individual elements. By way of example, the female fixing element may be formed by a plurality of spring-like elements which are arranged on the second component substantially along a circle and which are spaced apart from one another in the circumferential direction of the circle and projecting like a collar from the second component.

Im Folgenden wird die Erfindung im Zusammenhang mit der Zeichnung näher erläutert. Es zeigen:In the following the invention will be explained in connection with the drawing. Show it:

B. durch Laserauftragschweißen, Lasersintern oder durch ähnliche Verfahren, wie sie aus dem Bereich „Rapid Prototyping” bekannt sind. Mit derartigen Verfahren können auch bei geringen Stückzahlen bzw. bei Prototypenbauteilen vergleichsweise kostengünstig komplexe Geometrien hergestellt werden. 1 shows a component 1 , which may be, for example, a body component of a vehicle, of which several spring-like elements 2 . 3 , which together form a "female fixation element", stand out. The feathery elements 2 . 3 pointing in a transverse direction 4 a certain bending elasticity. The spring-like elements can be built up or produced in layers, for. As by laser cladding, laser sintering or by similar methods, as they are known in the field of "rapid prototyping".
