Linear transfer stroking boom

摘要

A linear transfer stroking boom has a housing suspended from a support which may be the travel carriage of an overlying longitudinally reciprocal shuttle. A cylinder assembly is mounted within the housing and includes a reciprocal piston rod on a longitudinal axis. A plurality of parallel spaced guide rods are slidably mounted upon and extend through the ends of the housing and outwardly thereof. Boom mount plates span the ends of the guide rods with the piston rod secured to one boom mount plate. A pair of parallel spaced boom extension arms are removably mounted upon the boom mount plates and extend forwardly of the housing. A workpiece gripping assembly spans and depends from the free ends of the boom arms. Reciprocal movement of the piston rod effects corresponding longitudinal movements of the boom arms in the same direction as and simultaneous with feed corresponding movements of the travel carriage.
