Gripper for axles
Challenge
Heavy railway axles needed to be supplied to a lathe. In this process, the shafts not only needed to be gripped but also moved linearly and swiveled freely in space.
Solution
Due to the heavy weight, a special gripper with a linear axis has been developed. The rotation was enabled via a servo swivel axis that was implemented in an infinitely rotating design. The loading stroke of 500 mm was given a servo motor design, as was the gripper itself. The result is a rugged system solution entirely driven by a servo motor.
