Abstract

The spindle (6) is axially movable with respect or a support member (8) by an electric linear motor (29). The operating head (5) is fitted with a pneumatic cylinder (53) collaborating with a piston (54) engaged with a stop part (61) carried by the support member (8) in order to balance the weight of the spindle (6), enabling a reduction of the power required by the linear motor (29). The operating head (5) is also fitted with a second pneumatic cylinder (86) collaborating with a corresponding piston (84), which carries a locking element (81) able to engage a rack (79) carried by the support member (8). The piston (84) is biased by a spring (96) engaged with the rack (79), both in the event of the non-balancing of the weight of the spindle (6) as well as the non-excitation of the linear motor (29), to automatically block the vertical shifting of the operating head (5). The spindle (6) is cylindrically shaped and has a ring-shaped shoulder (14), that allows easy assembly on a body (11) fitted with a pair of axially spaced rings (13), in which the spindle (6) is inserted so as to rest the shoulder (14) against the upper ring (13). Each ring (13) has a notch (18) and a tightening screw (21) of the notch (18) to angularly lock the spindle (6) on the body (11).
