Abstract

Die Erfindung betrifft eine Spannvorrichtung, die zum Beispiel zum Verspannen zweier Bleche vor dem Schweißen verwendet wird. Probleme herkömmlicher Spannvorrichtungen liegen insbesondere im festen Öffnungswinkel, der zu einer schlechten Zugänglichkeit führt.The invention relates to a clamping device, for example, for bracing two sheets is used before welding. Problems of conventional Clamping devices are in particular the fixed opening angle, the one to poor accessibility leads.

Um diese Probleme zu vermeiden und insbesondere unterschiedliche Öffnungswinkel einstellen zu können, wird eine Spannvorrichtung geschaffen, mit einem Spannarm (2, 32), der von einer Abtriebswelle eines mechanischen Untersetzungsgetriebes antreibbar ist, das aufweist:

  • eine Antriebsverzahnung (12, 48) aufweisende Antriebswelle (8, 43),
  • ein erstes Verstellzahnrad (4, 34) mit mindestens einem ersten Verstellverzahnungsbereich (6, 36, 37),
  • ein zweites Verstellzahnrad (9, 35) mit mindestens einem zweiten Verstellverzahnungsbereich (10, 38, 39),
  • mehrere Umlaufzahnräder (13a-e, 41), die in Eingriff mit den mindestens zwei Verstellzahnrädern sind,
wobei ein erster Verstellverzahnungsbereich des ersten Verstellzahnrades und ein zweiter Verstellverzahnungsbereich des zweiten Verstellzahnrades unterschiedliche Zähnezahlen aufweisen und/oder mit den ersten und zweiten Verstellverzahnungsbereichen in Eingriff befindliche Umlaufverzahnungsbereiche unterschiedliche Zähnezahlen aufweisen.
Figure 00000001
In order to avoid these problems and in particular to be able to set different opening angles, a clamping device is provided, with a clamping arm (2, 32) which can be driven by an output shaft of a mechanical reduction gear, which comprises:
  • a drive toothing (12, 48) having drive shaft (8, 43),
  • a first adjusting gear (4, 34) with at least one first adjusting toothed region (6, 36, 37),
  • a second Verstellzahnrad (9, 35) with at least one second Verstellverzahnungsbereich (10, 38, 39),
  • a plurality of epicyclic gears (13a-e, 41) engaged with the at least two pitch gears,
wherein a first Verstellverzahnungsbereich of the first Verstellzahnrades and a second Verstellverzahnrad the second Verstellzahnrades have different numbers of teeth and / or with the first and second Verstellverzahnungsbereichen engaged Umlaufverzahnungsbereiche have different numbers of teeth.
