Gripper for crankshafts


For loading and unloading a crankshaft production line, a flexible, efficiently optimized handling system needed to be developed that is capable of handling current and future 3-, 4- and 6-cylinder crankshafts of varying designs. Adjusting the different bearing clearances and thus the grip points, automatically and without additional drive technology was a special challenge here.


As the solution, two Zimmer Group standard grippers (GH6400 series) are fastened on a linear guide. An in-house clamp ensures the correct position when clamped. If a new shaft type is run, the grippers are locked in place at a fixed point, the clamp is released and the gantry adjusts the grippers to a new pitch.
