Description

Spannrahmen für Kfz-SeitenteileTensioning frame for car side parts
Die Erfindung betrifft einen Spannrahmen für Kfz-Seitenteile, mit einer Vielzahl von Spannelementen zum Einspannen eines Kfz-Seitenteils, mit zwei äußeren, im Wesentlichen vertikal ausgerichteten Anschlußträgern für Positionier- und Verriegelungseinheiten zum Fixieren in einer Schweißstation und mit einer Dockingeinheit für ein Transportmittel.The invention relates to a clamping frame for motor vehicle side parts, with a plurality of clamping elements for clamping a motor vehicle side part, with two outer, substantially vertically oriented connection carriers for positioning and locking units for fixing in a welding station and with a docking unit for a means of transport.
Beim Zusammenbau einer Kfz-Karosserie wird zunächst der Unterbau der Karosserie in eine Schweißstation gebracht, dort positioniert und verspannt. Die Kfz-Seitenteile werden entweder manuell oder automatisch in zugeordnete Spannrahmen eingelegt und darin verspannt sowie mit dem Spannrahmen in die Schweißstation gebracht und dort exakt so positioniert, dass die Seitenteile automatisch mit dem Unterbau und weiteren Teilen der Karosserie verschweißt werden können.When assembling a car body, the substructure of the body is first brought into a welding station, positioned and braced there. The vehicle side parts are either manually or automatically inserted into the assigned clamping frame and clamped there as well as brought into the welding station with the clamping frame and positioned there exactly so that the side parts can be welded automatically to the substructure and other parts of the body.
Ein bekannter Spannrahmen (DE 198 06 963 A 1 , insbesondere Figur 3) besitzt einen mehreckigen Grundriß. Die beiden äußeren Anschlußträger sind jeweils über obere Balken, die sich oberhalb des eingespannten Kfz-Seitenteils befinden und die Dockingeinheit tragen, sowie über untere Balken miteinander verbunden. Von diesen Balken gehen die Spannelemente aus. Der mehreckige Grundriß des Spannrahmens kann zu Störungen beim manuellen oder automatischen Einlegen der Kfz-Seitenteile in die Spannelemente, aber auch bei gegebenenfalls notwendigen Wartungs- oder Einstellarbeiten führen.A known stenter (DE 198 06 963 A1, in particular Figure 3) has a polygonal plan. The two outer connection carriers are each connected to one another via upper beams, which are located above the clamped vehicle side part and carry the docking unit, and via lower beams. The tensioning elements start from these bars. The polygonal layout of the clamping frame can lead to malfunctions when manual or automatic insertion of the vehicle side parts into the clamping elements, but also with any necessary maintenance or adjustment work.
Aufgabe der Erfindung ist es deshalb, den Spannrahmen montage- und wartungsfreundlicher zu gestalten.The object of the invention is therefore to make the stenter easier to assemble and maintain.
Diese Aufgabe wird dadurch gelöst, dass die beiden äußeren Anschlußträger lediglich über einen sich im wesentlichen horizontal erstreckenden, torsions- und biegesteifen Träger verbunden sind, an dem die Spannelemente und die Dockingeinheit befestigt sind, wobei der Träger in einer Projektion auf das Kfz- Seitenteil eine kleinere Höhe aufweist als das Kfz-Seitenteil. Damit wird erreicht, dass dieser einzige Träger praktisch von allen Seiten zugänglich ist, was sich vorteilhaft auf Montage- und Wartungsarbeiten auswirkt.This object is achieved in that the two outer connection carriers are connected only via a substantially horizontally extending, torsionally and flexurally rigid carrier to which the tensioning elements and the docking unit are fastened, the carrier in a projection onto the motor vehicle side part has a smaller height than the motor vehicle side part. So that is achieved that this single carrier is accessible from practically all sides, which has an advantageous effect on assembly and maintenance work.
Bei einer bevorzugten Ausführung besteht der Träger aus einem geschlossenen Profil. Er kann aber auch aus mehreren, zueinander parallelen Balken oder Profilen bestehen. In allen Fällen ist es möglich, alle Spannelemente auf einer Seite des Trägers bzw. eines Übergangsteils zur Dockingeinheit anzuordnen.In a preferred embodiment, the carrier consists of a closed profile. But it can also consist of several parallel bars or profiles. In all cases it is possible to arrange all clamping elements on one side of the carrier or a transition part to the docking unit.

Lediglich auf einer Seite des Trägers 1 ist eine Vielzahl von Spannelementen 6 zum Einspannen eines Kfz-Seitenteils 7 angeordnet. Einige Spannelemente 6 sind auch am Übergangsteil 4 angeordnet. Die Konstruktion der Spannelemente 6 ist an sich bekannt und braucht deshalb nicht weiter beschrieben zu werden.A large number of clamping elements 6 for clamping a motor vehicle side part 7 are arranged only on one side of the carrier 1. Some clamping elements 6 are also arranged on the transition part 4. The construction of the clamping elements 6 is known per se and therefore need not be described further.
Bei der in Figur 1 wiedergegebenen Ausführung besteht der Träger 1 aus einem torsions- und biegesteifen Hohlprofil, das einen rechteckigen bis quadratischen Querschnitt besitzt. Die Spannelemente 6 sind unmittelbar auf einer Seite des Trägers 1 oder auf Kragarmen 8 angeordnet, die von dieser Seite des Trägers 1 ausgehen. Bei der in Figur 2 wiedergegebenen Ausführung besteht der Träger 1 aus mehreren zueinander parallelen Balken 9 oder Profilen. Dargestellt ist ein Träger aus zwei zueinander parallelen Balken 9. Auch bei dieser Ausführung sind die Spannelemente 6 entweder direkt auf den Balken 9 angeordnet oder auf Kragarmen 8, die von den Balken 9 ausgehen.In the embodiment shown in Figure 1, the carrier 1 consists of a torsionally and bending-resistant hollow profile which has a rectangular to square cross section. The tensioning elements 6 are arranged directly on one side of the carrier 1 or on cantilever arms 8 which start from this side of the carrier 1. In the embodiment shown in Figure 2, the carrier 1 consists of several mutually parallel beams 9 or profiles. A support made of two parallel bars 9 is shown. In this embodiment, too, the tensioning elements 6 are either arranged directly on the bars 9 or on cantilever arms 8 which extend from the bars 9.
Bei allen Ausführungen besitzt der Träger 1 , auch in der Ausführung aus mehreren zueinander parallelen Balken 9 oder Profilen, in einer Projektion auf das Kfz-Seitenteil 7 eine geringere Höhe als das Kfz-Seitenteil 7. In all versions, the carrier 1, also in the version consisting of several mutually parallel beams 9 or profiles, has a lower height than the vehicle side part 7 when projected onto the vehicle side part 7.
