CA 2339845

The invention relates to a method and device for mechanically machining work pieces and for assembling/disassembling modules. The inventive method is provided for use in machine tools such as, for example, in computer numerical controlled grinders, milling machines, boring machines and, among other things, in transfer lines for assembling/disassembling modules. The inventive method for mechanically machining work pieces and for assembling/disassembling modules in which the work pieces and/or modules are fastened on adjustable and exchangeable clamping plates (2) is characterized in that the clamping plates (2) are mounted as part of a holding device (1) or of a rotary table (33) in a floating manner by magnetic forces and/or gaseous and/or liquid media. In addition, the inventive method is characterized in that the clamping plates can be adjusted and positioned. By using a sensor system, both the contact freedom of the supporting elements of the clamping plate (2) in a magnetic retaining ring (8) or in the rotary table housing (37), and the µm-exact positioning of the work pieces/modules with regard to the tool systems and assembly/disassembly systems are ensured by a measuring and control system.

L'invention concerne un procédé et un dispositif pour l'usinage mécanique de pièces et pour le montage/démontage de modules. Ce procédé et ce dispositif sont destinés à des machines-outils, par ex. des meuleuses, fraiseuses, aléseuses à commande numérique ou autres, et à des lignes de transfert pour le montage/démontage de modules. Selon le procédé de l'invention, les pièces et/ou les modules sont fixés sur des plaques de fixation (2) mobiles et interchangeables. Ce procédé est caractérisé en ce que les plaques de fixation (2) peuvent être montées, déplacées et positionnées de manière flottante par des forces magnétiques et/ou des milieux gazeux et/ou liquides, en tant que partie d'un dispositif de fixation (1) ou d'un plateau circulaire. Au moyen d'un système de détecteurs, la liberté de contact des éléments porteurs des plaques de fixation (2) dans un anneau de maintien magnétique (8) ou dans un boîtier de plateau circulaire (37) et le positionnement à un micron près des pièces/modules par rapport aux systèmes d'outils et de montage/démontage, sont assurés par l'intermédiaire d'un système de mesure et de régulation.
