Claims

[Claims for Utility Model Registration] (1) A magnetic pole assembly comprising a plurality of magnetic pole members arranged at intervals in one direction, including a space extending in the direction in which the magnetic pole members are arranged, and a plurality of magnetic pole members that attract magnetic bodies. a plurality of first permanent magnets disposed between the magnetic pole members; a movable body disposed in the space so as to be slidable in the arrangement direction; a plurality of second permanent magnets disposed on the movable body corresponding to the magnetic pole members to selectively place the working surface in an energized state and a de-energized state in cooperation with the magnets;
A permanent magnet in which a magnetic pole surface of the permanent magnet faces the magnetic pole members on both sides of the first permanent magnet, and a magnetic pole surface of the second permanent magnet faces the magnetic pole member so as to be movable relative to the magnetic pole member. Check. (2) The magnetic pole assembly has a rectangular cross section perpendicular to the arrangement direction, and the working surface is formed on at least two surfaces around the space, Permanent magnetic chuck described in item 1). (3) The movable body includes at least one yoke;
The permanent magnet chuck according to claim (1) of the utility model registration, comprising a spacer disposed on each of at least two surfaces of the yoke facing the magnetic pole member and accommodating the second permanent magnet. . (4) The magnetic pole assembly comprises a bottom plate, and a laminate fixed on the bottom plate, in which the magnetic pole members are stacked with a non-magnetic member in between. Permanent magnetic chuck as described. (5) The permanent magnet chuck according to claim 1, wherein the space is defined by the laminate. (6) The utility model, wherein the first permanent magnets are arranged with magnetic pole faces of the same polarity facing each other, and the second permanent magnets are arranged with their magnetization directions alternately reversed to the arrangement direction. Scope of registration claims (1)
Permanent magnetic chucks listed in ).
