Abstract:
An automatic production machine comprising:a rotor that is rotatable around a vertical axis of the machine, several receptacles on a periphery of the rotor for workpieces to be assembled or for sub-assemblies, a central drive means for the rotor for moving the rotor and the receptacles on it in a stepwise movement from a work position to a next work, position, a plurality of working stations around the rotor, each working station on a working position, a first functional or tool elements at each work position or station, a control unit being common for the first tool elements and driven by a central drive assembly for producing a first and a second type of controlled movement of the first tool elements in synchronization with the stepwise movement of the rotor, wherein the common control unit has at least two lifting or tie rods which are guided in a central part of a machine frame with their axis parallel to the machine axis, but radially offset from it and offset from another and which are axially moved up and down by the central drive assembly, at least two disk cams in the direction of the machine axis one above the other, the disk cams being attached each on an axially movable lifting or tie rod of the at least two lifting and tie rods, each disk cam having its own lifting rod and forming a cam surface for control elements of the first tool element such, that upon up and down movement of the lifting or tie rods and their disk cams, the first tool elements are driven for the first type of movement by the axial movement of a first lifting or tie rod of the at least two lifting and tie rods with the first type of movement being a movement in axial direction in respect to the vertical machine axis, and the first tool element being driven for the second type of movement by the axial movement of a second lifting or tie rod of the at least two lifting and tie rods.
