Description
Die vorliegende Erfindung betrifft eine Schraube mit einem Kopf und zwei an beiden Seiten des Kopfes angeordneten Außengewinden.The The present invention relates to a screw with a head and two external threads arranged on both sides of the head.
In der Automobilindustrie verwendet man zur Lösung konstruktiver Probleme gerne Schrauben mit einem Kopf und zwei an beiden Seiten des Kopfes angeordneten Außengewinden. Solche Schrauben wurden gemäß dem Stand der Technik bisher dergestalt hergestellt, dass man eine "normale" Schraube mit einem verhältnismäßig großem Kopf herstellte und in die dem Gewinde abgewandte Seite des Kopfes konzentrisch eine Gewindebohrung mit einem Innengewinde anbrachte. In dieses Innengewinde wurde dann ein Stift mit einem Außengewinde eingeschraubt.In The automotive industry is used to solve constructive problems like screws with a head and two arranged on both sides of the head External threads. Such screws were according to the state The technology so far produced in such a way that one a "normal" screw with a relatively large head manufactured and in the thread facing away from the side of the head concentric a threaded bore with an internal thread attached. In this Internal thread was then screwed in a pin with an external thread.
Dies hatte folgende Nachteile:This had the following disadvantages:
Es war ein ungewöhnlich großer, und damit auch schwerer Kopf erforderlich, der schwierig herzustellen war. Zusätzlicher Aufwand entstand bei der Herstellung des Innengewindes. Trotz der ungewöhnlichen Größe des Kopfes der Schraube war das entsprechende Innengewinde sehr kurz und konnte deshalb keine großen Kräfte aufnehmen. Außerdem bestand die Gefahr, dass sich der in das Innengewinde eingesetzte Stift durch Vibrationen oder bei Montage- oder Reparaturarbeiten losdreht.It was an unusual one greater, and thus heavy head required, which is difficult to manufacture was. additional Effort was incurred in the production of the internal thread. Despite the unusual Size of the head The screw was the corresponding internal thread very short and therefore could no big ones personnel take up. It also existed the danger that the pin inserted into the internal thread loose by vibration or during assembly or repair work.
Zur Lösung dieser Probleme hatte man bisher lediglich eine einstückige Herstellung einer solchen Schraube vorgesehen. Hierzu ist jedoch eine spezielle Maschine, und damit ein sehr großer Aufwand, erforderlich.to solution These problems were previously only a one-piece production provided such a screw. However, this is a special one Machine, and therefore a very big effort, required.
Aufgabe der vorliegenden Erfindung ist es daher, eine Schraube mit einem Kopf und zwei an beiden Seiten des Kopfes angeordneten Außengewinden zu schaffen, die auf den üblichen Maschinen gefertigt werden kann, und die trotzdem die Nachteile der Anbringung eines Innengewindes in dem Kopf (Volumen und Gewicht des zu vergrößernden Kopfes, geringe mechanische Belastbarkeit des kurzen Innengewindes, mögliches Losdrehen des Innengewindes) vermeidet.task The present invention is therefore a screw with a Head and two arranged on both sides of the head external threads to create that on the usual Machines can be manufactured, and still the disadvantages of Attaching an internal thread in the head (volume and weight of the to be enlarged Head, low mechanical load capacity of the short internal thread, potential Loosen the internal thread) avoids.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Stift, der das zweite Außengewinde trägt, durch eine Schweißung mit dem Kopf verbunden ist. Bei anderen Anwendungsfällen kann der Stift auch anstelle eines Außengewindes glatt oder mit anderen Strukturen versehen sein.According to the invention this Task solved by that the pin, which carries the second external thread through a weld connected to the head. In other applications, the Pin also instead of an external thread be smooth or provided with other structures.
Besonders bevorzugt ist es dabei, wenn es sich bei der Schweißung um eine Reibschweißung handelt. Diese lässt sich nämlich am besten in den Herstellungsprozess integrieren.Especially it is preferred when it comes to the weld a friction welding is. This leaves Namely best integrate into the manufacturing process.
Es verbleibt dann das Problem, dass zwischen dem Kopf und dem zweiten Gewinde eine Schweißnaht entsteht, so dass beispielsweise eine Mutter auf dem zweiten Gewinde nicht bis zum Anschlag an dem Kopf aufgeschraubt werden kann.It then the problem remains that between the head and the second Thread a weld arises, for example, a nut on the second thread can not be screwed to the stop on the head.
Es ist daher besonders bevorzugt, dass in der dem ersten Gewinde abgewandten Seite des Kopfes eine zylindrische Ausnehmung konzentrisch zu dem Kopf angeordnet ist, in der sich die Schweißung befindet. Auf diese Weise kann auch das zweite Ge winde bis zum Kopf durchlaufen, zusätzlich kann eine höhere Festigkeit der Schweißverbindung erreicht werden.It is therefore particularly preferred that in the first thread facing away from Side of the head has a cylindrical recess concentric with the Head is arranged, in which the weld is located. In this way can also go through the second thread to the head, in addition, one higher Strength of the welded joint be achieved.
Vorzugsweise weist die Ausnehmung dabei eine Tiefe auf, die der Breite der Schweißung entspricht.Preferably The recess has a depth which corresponds to the width of the weld.
Besonders kostengünstig kann die Ausnehmung durch Eindrücken in den Kopf hergestellt sein.Especially economical can the recess by pushing be made in the head.
Zur Erleichterung der Montage des Stiftes mit dem Außengewinde ist es weiter bevorzugt, wenn die Außenwände der Ausnehmung schräg nach innen zulaufend verlaufen.to Facilitating the assembly of the pin with the external thread, it is further preferred if the outer walls of the Recess at an angle tapering inwards.
Weiter ist es bevorzugt, wenn der Kopf einen Außenantrieb aufweist, besonders bevorzugt ist dabei ein Sechskant.Further it is preferred if the head has an external drive, especially preferred is a hexagon.
