ABSTRACT:
A device for the manipulation of workpieces or the like has a stepping transmission with a click-stop setting and located in a gearbox and it regulates two reciprocal motions of the workpiece holding mechanism through cam plates fastened to a drive shaft. A first motion is that of a carriage sliding on the gearbox housing and a second motion is that of a holder guided on the carriage for movement essentially perpendicular to the first motion. Two pair of complementary cam plates is provided on the drive shaft for each motion for the purpose of greater precision of the reproducibility of the prescribed motions. The first pair of complementary cam plates is coupled to the carriage through a first control shaft and a crank assembly consisting of a crank and a coupling, while the second pair of complementary cam plates operates in combination with the holder through a second control shaft. The crank and the coupling in the click-stop setting of the stepping transmission are in a dead center position.
