MAGNET CHUCK

摘要

A magnet chuck includes a piston that is displaced inside a second sliding hole of a cylinder tube. One end surface of the piston abuts against a plate member when the piston reaches one displacement end point, whereas another end surface of the piston abuts against an entry member of a head cover when the piston reaches another displacement end point. At least one, and preferably both, of a first damper on the one end surface, and the second damper on the other end surface are disposed on the plate member.

主权项

1. A magnet chuck that attracts and retains a workpiece with a magnetic force of a permanent magnet, comprising:
a housing including a cylinder tube formed with a sliding hole therein through which a piston is displaced, and a head cover attached to the cylinder tube and configured to close one end of the sliding hole; a retaining member connected to the piston and configured to retain the permanent magnet; and a partitioning member positioned and fixed in interior of the housing, and configured to form an inner chamber in interior of the cylinder tube together with the piston; wherein the magnet chuck further includes at least one of a first damper and a second damper, the first damper being disposed on either one of the partitioning member or the piston and configured to buffer vibrations when the piston abuts against the partitioning member, the second damper being disposed on either one of the piston or the head cover and configured to buffer vibrations when the piston abuts against the head cover.
