Description:
Abstract:

An automatic framing system comprises at least one framing station located along a path. Workpiece carrying pallets are propelled along the path by draw bars. At each framing station, a critical lift lifts the workpiece from the pallet to a work station. The critical lift comprises a first lift mechanism for raising a frame located under the workpiece from a lowered position remote from the workpiece to an intermediate position proximate the workpiece. A second lift mechanism raises the frame from the intermediate position to a third position to contact and lift the workpiece from the pallet to the work station. Side gates pivot between open and closed configurations about respective horizontal axes located near the critical lift. The critical lift frame interlocks with the closed side gates when the frame is in its third position. When in the closed configuration, tooling within the side gates clamps the workpiece at the work station. The workpiece is then welded or otherwise processed by suitable equipment at the framing station.
