PERMANENT ELECTROMAGNETIC INDEXING APPARATUS
First Claim
1. A permanent electromagnetic indexing apparatus comprising:
- a chassis;
a carrier having a receiving portion and a connection part, said connection part being pivoted to said chassis; and
at least two magnetic sets, each of which has a first permanent magnet, a magnetic-conductive member, a second permanent magnet, and a magnetizing coil, each of said first permanent magnets being mounted to said magnetic-conductive member, each of said magnetic-conductive member being mounted to said second permanent magnet, each of said magnetizing coils surrounding said second permanent magnet, said magnetic sets being mounted to said receiving portion of said carrier, said magnetic-conductive members becoming a working surface on which a workpiece can be put;
whereinwhen each of said magnetizing coils is electrically conducted, the polarity of each of said magnetic-conductive members can be further changed and thus said workpiece can be fixed to or removed from said working surface.

Abstract
A permanent electromagnetic indexing apparatus includes a chassis, a carrier pivoted to the chassis, and a plurality of magnetic sets. Each of the magnetic sets includes a first permanent magnet, a magnetic-conductive member, a second permanent magnet, and a magnetizing coil. Each of the first permanent magnets is mounted to the magnetic-conductive member. Each of the magnetic-conductive members is mounted onto the second permanent magnet. Each of the magnetizing coils surrounds the second permanent magnet. The magnetic sets are mounted to the carrier to enable the magnetic-conductive members to become a working surface for placing a workpiece thereon. When each of the magnetizing coils is electrically conducted, the polarity of each of the magnetic-conductive members can be changed and then the workpiece can be fixed to or removed from the working surface. In this way, the workability can be enhanced to enable preferably flexible and variable processing.
