Abstract:
An automatic device for locking of tool holders ( 12 ) on lathes and machinery performing machining by chip removal, particularly suitable to be used on multi-spindle and single spindle CNC lathes, on transfer machines, milling centres of any kind and, in general, on all types of machine tools which perform machining by chip removal, comprises a support body ( 14 ) anchored to the machine tool and surmounted by a plate ( 16 ), said device comprises, for each of said tool-holders ( 12 ), a pawl ( 18 ) provided with a female truncated-cone recess ( 24 ), cooperating with a nut screw ( 36 ) and moved automatically vertically to engage in contact with a truncated cone collar appendage ( 40 ) made in a recess ( 38 ) in the rear ( 12 ′). The movement in the vertical direction of the pawls ( 18 ) is produced by means of individual motors ( 46 ), equipped with a shaft ( 48 ) which protrudes from their lower face and engages to the upper end of said nut screw ( 36 ).
