Magnetic holding device

摘要

A magnetic holding device includes a hollow cylinder having an axis and closed ends. A rodless piston having an elongated radial cross-section is slidable within the cylinder for movement between the ends. At least one magnet is carried by the piston. The piston is driven back and forth in the cylinder by air pressure. The magnet is adapted to pick up a workpiece adjacent to one end of the cylinder when the piston is driven toward that end of the cylinder.
