Abstract
A blocking device of tool-holders on lathes, especially for the rapid and precise blocking of tool-holders on CNC (Computer Numerical Control), single spindle or multi-spindle lathes as well as on transfer machines, milling centres of any kind and, in general, on machine tools which perform machining by chip removal, is paired with a tool-holder, motorized or non-motorized, connected to the existing support on said lathes and comprises an anchoring pawl provided with a female truncated-cone shaped recess. Said pawl is moved vertically with respect to the longitudinal axis of said tool-holder by mechanical or hydraulic means driven to engage said female, truncated-cone shaped recess with an inclined, male truncated-cone appendage made on said tool-holder.
Claims10
A device (10) for blocking tool-holders on lathes, in particular for the rapid and precise blocking of tool-holders on CNC (Computer Numerical Control), single spindle or multi-spindle, lathes as well as on transfer machines, milling centres of any kind and, in general, on machine tools which perform machining with chip removal, paired with a tool-holder (12) motorised or non-motorised connected to the support (14) existing on said lathes, characterised in that it comprises an anchoring pawl (16) with a female, truncated-cone shaped recess (22) moved vertically with respect to the longitudinal axis of said tool-holder (12) by mechanical or hydraulic means to drive said pawl to engage said female, truncated-cone shaped recess (22) it is provided with, in an inclined, male truncated-cone appendage (38) made on said tool-holder (12).
