Abstract

Le présent perfectionnement concerne un dispositif servant à faire avancer des pièces sous forme de barres dans un tour automatique multibroches. Le cylindre à air comprimé 13 est muni d'une tige de piston 13' qui le traverse de part en part et dont l'extrémité opposée au tour automatique presse, au moyen d'un verrou 23 et d'une tige de poussée 24, le chariot d'avance 12 contre une plaque 25 qui est fixée à l'extrémité côté tour automatique du cylindre, tant que de l'air comprimé se trouve au raccordement A du cylindre. Ce perfectionnement a pour avantage de permettre le verrouillage entre le cylindre à air comprimé et le chariot d'avance moyennant l'emploi d'éléments relativement peu onéreux.The present improvement relates to a device for advancing parts in the form of bars in a multi-spindle automatic lathe. The compressed air cylinder 13 is provided with a piston rod 13 'which passes right through it and whose end opposite the automatic lathe presses, by means of a latch 23 and a push rod 24, the advance carriage 12 against a plate 25 which is fixed to the automatic lathe side end of the cylinder, as long as there is compressed air at connection A of the cylinder. This improvement has the advantage of allowing locking between the compressed air cylinder and the advance carriage by using relatively inexpensive elements.
