Description
Kurve 17 der Leitschiene 12, längsverschiebbar angetrieben, so daß das mit dem Kopfstück 2 versehene Ende der Welle 8 aus der Richtung der Achse 16 ausgeschwenkt werden kann.Curve 17 of the guide rail 12, driven to be longitudinally displaceable, so that the one provided with the head piece 2 The end of the shaft 8 can be pivoted out of the direction of the axis 16.
Beim Absenken der Welle 8 läuft die Steuerrolle 11 auf der Leitschiene 12 und rückt die Welle 8 aus der Richtung der Achse 16. Dabei wird das Kopfstück 2 vor die Nabenöffnung 19 geschoben. In diesem Moment gelangt die Steuerrolle 11 auf die Schrägfläche 17 der Leitschiene 12, so daß berm weiteren Absenken der Welle 8 gegen die Radiatorenelemente 20 das Kopfstück 2 parallel zu der Schrägfläche 17 läuft und in die gezeichnete Lage gelangt.When the shaft 8 is lowered, the control roller 11 runs on the guide rail 12 and moves the shaft 8 out the direction of the axis 16. The head piece 2 is pushed in front of the hub opening 19. In this Moment arrives the control roller 11 on the inclined surface 17 of the guardrail 12, so that over further Lowering the shaft 8 against the radiator elements 20, the head piece 2 parallel to the inclined surface 17 runs and gets into the position shown.
Selbstverständlich ist die Vorrichtung so ausgebildet, daß die Steuerrolle 11 beim Absenken und Anheben
der Welle 8 an der Leitschiene 12 anliegt, bzw. können mehrere Führungsrollen vorgesehen sein.
Der Grundkörper 1 ist derart eingestellt, daß die Hülse 4 bei abgesenkter Welle 8 auf dem oberen Bördel
21 aufliegt und damit das Absenken des Kopfstücks 2 begrenzt, während die Buchse 5 mit ihrem
Zentrierkegel 6 unter dem Druck der Feder 9 in die ίο Nabenöffnung 19 gepreßt wird und den oberen Bördel
21, bezogen auf die Brennerachse, zentriert. Damit wird die genaue Schweißlage der Elektrode zum
zu verschweißenden Bördel 18 sichergestellt.Of course, the device is designed in such a way that the control roller 11 rests against the guide rail 12 when the shaft 8 is lowered and raised, or several guide rollers can be provided.
The base body 1 is set in such a way that the sleeve 4 rests on the upper flange 21 when the shaft 8 is lowered and thus limits the lowering of the head piece 2, while the bushing 5 with its centering cone 6 is pressed into the hub opening 19 under the pressure of the spring 9 is and the upper flange 21, based on the burner axis, centered. This ensures the exact welding position of the electrode in relation to the flange 18 to be welded.
