Title (EN) DEVICE FOR MACHINING THE SURFACE OF WORKPIECES HAVING IRREGULAR CONTOURS
(FR) DISPOSITIF D"USINAGE DE LA SURFACE D"UNE PIECE PRESENTANT DES CONTOURS IRREGULIERS
Abstract:
(EN) A device for machining the surface of workpieces having irregular contours, having the form of a rotating body set against the surface to be machined and which periphery carries the tools for machining the surface of the workpiece, the rotating body is divided into a plurality of sections (21 ...), driven by a common shaft (23). For the purpose of individual setting of the sections (21 ...) against the surface to be machined, the shaft (23) passes excentrically through the sections (21 ...), there being on the shaft drive wheels (231) that act internally on each individual section and, also for each section at least one guide (25) that is easily rotatable in respect of the shaft (23) and also in respect of the section (21) against which it presses, so that the driven sections (21 ...) can, if necessary, be forced individually (arrow C) against the force of s return spring (241) and thus can be set against the surface to be machined.
(FR) Un dispositif d"usinage de la surface de pieces a usiner presentant des contours irreguliers qui a la forme d"un corps rotatif place contre la surface a usiner, portant sur sa peripherie des outils d"usinage de la surface de la piece et divise en une pluralite de sections (21 ...), entrainees par un arbre commun (23). De maniere a ajuster individuellement les sections (21 ...) contre la surface a usiner, l"arbre (23) passe excentriquement au travers des sections (21 ...) et des roues d"entrainement (231) montees sur l"arbre (23) agissent interieurement sur chaque section individuellement, chaque section ayant au moins un guide (25) pouvant tourner facilement par rapport a l"arbre (23) et egalement par rapport a la section (21) sur laquelle il appuie, de sorte que les sections (21 ...) entrainees peuvent, si necessaire, etre poussees individuellement (fleche C) contre la force d"un ressort de rappel (241) et etre ajustees contre la surface a usiner.
