ABSTRACT:
A machine has an intermittently rotating table for holding parts to be worked on or assembled. Operating units (20, 21, 25) are actuable either simultaneously for all units or groups of units, or independently of one another. The operating units can be mounted vertically over or under the table and also laterally and can receive the rotary movement of a central wheel or independent motors. According to a preferred embodiment, the control of the feed is effected by the central shaft (4). During a work cycle, this shaft makes a vertical movement and transmits that movement to the operating units (20, 21) by radial linear cams (16, 17, etc.), i.e., feed and return occur during a single movement of the shaft (4), for example, downward. During idle time, i.e., the time used to move and index the table (8) but not to perform the work, the central shaft (4) is also turned through a certain angle so that the linear cams are no longer in contact with the operating units and in this position the central shaft is returned without influencing the operating units. Thus it is possible to give the operating units any feed and return characteristic of machines with rotary cams, while having very much simplified kinematics.
