ABSTRACT:
A fully enclosed cam-actuated drive device for providing both lift and translational movements, incorporating protection against damage in either horizontal or vertical overload situations, achieved by providing optional spring protection along the vertical and/or horizontal axes, a roller gear cam for lift motion, a barrel cam for translational motion, translation guide rods, a translational carriage assembly slidably received on the translation guide rods, an input drive shaft, and vertical lift rods. The device may be configured as a walking beam device to impart a U-shaped output motion, or alternatively a closed box-shaped motion, as desired. A split carriage assembly reduces backlash of the device and a sliding dust cover prevents foreign objects from entering the drivers cam-actuated internal operating structure.
