Abstract

Ce procédé de perçage par retournement ne requiert aucun démontage de la pièce à usiner en cours d'opération. Il consiste en effet à monter la pièce sur un support pouvant tourner autour d'un axe orthogonal à l'axe de perçage; la pièce peut ainsi être d'abord percée à une de ses extremités, puis être retournée par rotation de son support de 180 degrés , autour de son axe, pour être percée à son autre extrémité. Le dispositif destiné à la mise en oeuvre de ce procédé, se montant sur une machine-outil, est essentiellement constitué par une embase fixée sur la machine-outil, par un support monté tournant sur l'embase et comportant des moyens de serrage de la pièce à usiner, et par des moyens aptes à verrouiller le support tournant sur l'embase dans au moins deux positions séparées par une rotation de 180 degrés . Applications : perçage profond d'une pièce de part en part, alésage d'une pièce à ses extrémités, execution de centres aux extrémités d'une pièce.This reverse drilling method does not require any disassembly of the workpiece during operation. It consists of mounting the part on a support capable of rotating about an axis orthogonal to the drilling axis; the part can thus be first pierced at one of its ends, then be turned over by rotating its support 180 degrees, around its axis, to be pierced at its other end. The device intended for the implementation of this method, being mounted on a machine tool, is essentially constituted by a base fixed to the machine tool, by a support mounted to rotate on the base and comprising means for clamping the workpiece, and by means capable of locking the rotating support on the base in at least two positions separated by a rotation of 180 degrees. Applications: deep drilling of a part right through, reaming a part at its ends, execution of centers at the ends of a part.
