ABSTRACT:
Tapping apparatus comprising: a body (5) suitable for being mounted on a moving element (4) of a press; a system of multiplying gears (14) having their axes parallel to the direction (F) of motion of said element, and placed on said body; a motion transforming device having a large pitch screw (26) and nut (27) for transforming the linear stroke of said element into a rotary motion which is applied to a first gear wheel of the system; and a tapping head (18) which is rotated by the last gear wheel (17) of the system and which is driven in translation by the body, said head comprising a fixed casing (32), a spindle (36) which pivots in said casing and is rotated by the last gear wheel (17) and a tool-carrying clamp (51) which is rotated by the spindle and which is capable of longitudinal displacement against pneumatic return means (F.sub.d) of adjustable force.
Applicable to machine tools.
