Problems solved by technology

In addition, the current ring-type electro-permanent magnetic chucks have only one holding surface. For the occasions that require two holding surfaces, only the method of adding ring-type electro-permanent magnetic chucks or adopting mechanical structure conversion is adopted, which increases the equipment cost. cost or possibility of failure

Abstract

The invention provides a ring type electric permanent-magnetic chuck comprising a shell and at least one magnetic unit arranged inside the shell. The shell covers the magnetic unit, and the shell and the magnetic unit are fixed together through screws. The magnetic unit comprises a reversible magnetic ring, an irreversible magnetic ring, a magnetism conducting plate and a magnet exciting coil. The irreversible magnetic ring is inlaid into the reversible magnetic ring, and the irreversible magnetic ring and the reversible magnet ring are identical in height. The magnetism conducting plate is fixedly arranged on the two end faces, attached to each other, of the reversible magnetic ring and the irreversible magnetic ring. The magnet exciting coil is wound around the outer portion of the irreversible magnetic ring, and the irreversible magnetic ring is relatively wrapped inside the magnet exciting coil. The ring type electric permanent-magnetic chuck can conduct double-face operation; and when the ring type electric permanent-magnetic chuck works, the attraction operation force applied on a workpiece is balanced, and the attraction force is large.

Description

technical field [0001] The invention belongs to the technical field of ring-type electro-permanent magnet chucks, and in particular relates to a magnetic unit and ring-type electro-permanent magnet chucks. Background technique [0002] The electronically controlled permanent magnet chuck is a new type of lifting equipment that combines the characteristics of electromagnetism and permanent magnets. Among them, the magnetic pole structure of the electronically controlled permanent magnet chuck is divided into two parts, the outer part is the magnetic yoke, and the inner part is composed of the upper layer of high coercive force NdFeB and magnetic pole pieces, in which the NdFeB permanent magnets are distributed on the side of the magnetic pole piece and the magnetic yoke. Between; the lower layer is composed of AlNiCo magnets with medium coercive force and excitation coils that can be magnetized forward and reverse. When the electronically controlled permanent magnet chuck is...
