Device for machining a groove having a circular generatrix and a curved directrix on the faces of at least one slot in a workpiece (mechanical component)

摘要

The device includes at least one ball-carrier (11) mounted so as to slide on a platen (13) of a press and, for each ball-carrier (11), at least one connecting piece (connecting rod) (16) mounted so as to pivot with respect to the said press platen and with respect to the ball-carrier (11), this connecting piece (16) including a peripheral part (18a) in contact with an element (19), integral with the other platen (7) of the press and having a hole (20) in which a roller (21) slides, this roller being mounted on a spindle (22) fixed to the ball-carrier (11), the connecting piece (16), the peripheral part (18a) and the hole (20) being shaped in a predetermined manner so that the centre of the ball (14) describes, with respect to the workpiece (1), a relative path (37) identical to the curved directrix desired for the groove when the two press platens (7, 13) move towards each other.
