  • the invention is therefore based on the object of creating a modular machining center with various work modules driven by a drive unit, in which the drive can be integrated into the machining center in a space-saving and economical manner and the possibility is given Change work modules quickly and safely without having to move the modules sideways.
  • Another task is to create a multifunctional drive unit which can be optimally adapted to the particular structure of the processing unit.
  • the main drive of the machining center is designed as a separately manageable base module.
  • this has the advantage that the maximum power of the drive is present at the location of the machining center where the largest power reserves are required.
  • the further work modules no longer require a separate drive, as a result of which the base of these work modules can be constructed not only more simply, but with a unit grid dimension corresponding to the base module.

  • the development according to claim 3 enables a more flexible integration of the main drive into the machining center, with the functionality of the press being increased at the same time.

  • the bases of the work modules preferably have the same height as the base module which can be handled separately.
  • the construction of the machining center according to the invention results in a maximum of flexibility in the assembly of the components with the simultaneous preference of arranging the drive at the optimal position in the machining center.

Abstract

L'invention décrit un centre d'usinage modulaire possédant différents modules de travail (6, 8, 10) actionnés par un dispositif d'entraînement et comportant des outils (12) à commande contrôlée en temps, comme par exemple, outils de cintrage, systèmes d'alimentation, stations de soudage, unités de montage etc...Le dispositif d'entraînement se présente sous la forme d'un module à commande séparée formant une base (2), comportant la commande principale (4) du centre d'usinage et présentant une largeur (ERM) correspondant à la dimension modulaire unitaire des modules de travail (6, 8) intégrés dans le centre d'usinage. La puissance est transmise de la commande principale (4) aux modules de travail individuels (6, 8, 10) par l'intermédiaire de roues dentées (19, 21, 30, 32, 34, 36) à engrenage solidaire reliant les plans d'interface (ES) situés entre le module de base (2) et le module d'usinage (10) équipé et placé au-dessus du premier, d'une part, ainsi qu'entre les modules de travail contigus (6, 8), d'autre part.
