Abstract

Machine à copier à lecture optique dont la liaison entre l'organe produisant les déplacements de la tête de lecture optique nécessaires pour que cette tête suive le dessin et la broche portant la piece à usiner est assurée par deux vis sans fin solidaires l'une de l'autre et situées dans le prolongement l'une de l'autre, deux pas différents. La vis à grand pas produit les déplacements de la tête de lecture par rapport au dessin et la vis à petit pas les déplacements de la broche porte-pièce par rapport à l'outil d'usinage, le rapport entre les pas des deux vis correspondant à l'échelle du dessin. Application à la reproduction des dessins.Optical reading machine whose connection between the member producing the movements of the optical reading head necessary for this head to follow the pattern and the spindle carrying the workpiece is provided by two worm screws integral with one of the other and located in the continuation of one another, two different steps. The coarse-pitch screw produces the displacements of the read head relative to the drawing and the small-pitch screw the displacements of the workpiece spindle relative to the machining tool, the ratio between the pitches of the two screws corresponding to the scale of the drawing. Application to the reproduction of drawings.
