Abstract

Le dispositif de sécurité permet d'exécuter certains types de travaux sur machine-outil en ayant les mains libres et sans qu'elles soient en danger. Le porte-outil 13 est suspendu à une goupille 16 transversale fixée dans la paroi cylindrique de la broche 10 et il est traversé par un passage 19 communiquant avec un circuit d'air basse pression. Une lame 25, solidaire de la broche 10, peut obturer le passage 19 quand le porte-outil ou son outil 33 est arrêté par un obstacle anormalement placé sur la trajectoire de l'outil, par exemple une main ou un doigt. Des organes pneumatiques du circuit d'air basse pression agissent a ors pour faire remonter aussitôt la broche au point haut. Application : machine-outil, notamment presse pneumatique.The safety device allows certain types of work on machine tools to be carried out with your hands free and without being in danger. The tool holder 13 is suspended from a transverse pin 16 fixed in the cylindrical wall of the spindle 10 and it is crossed by a passage 19 communicating with a low pressure air circuit. A blade 25, integral with the spindle 10, can block the passage 19 when the tool holder or its tool 33 is stopped by an obstacle abnormally placed in the path of the tool, for example a hand or a finger. Pneumatic members of the low pressure air circuit act at once to immediately raise the spindle to the high point. Application: machine tool, in particular pneumatic press.
