ABSTRACT:
Machine with intermittently rotary workpiece-holding table makes it possible to perform with great rapidity the working and assembly of pieces requiring great precision. It comprises work units placed above (8), below (8') and laterally (8") to rotary table (14) and respective control elements (7a, 15, 7b, FIGS. 1a and 1b) to determine the advance and return movements of the work units. The control units comprise, for each of the work units placed above (8, FIG. 1), a linear cam (7a) and a reversed linear cam (7b), angularly out of phase, controlling a lever system (15) carrying the corresponding tappet. The cams are placed in the axial direction on a rotating body (6). With respect to known machines that exhibit an active travel and an empty return travel, the hourly production theoretically is doubled.
