Problems solved by technology

Since part of the epoxy resin is distributed on the upper surface of the suction cup, the filling in the gap between the magnetic pole units is epoxy resin or granular material, and the rigidity and strength of the suction cup are poor, which makes the electric permanent magnet suction cup expand and expand in more fields. Application creates certain limitations

Abstract

The invention discloses an assembled electric permanent magnet sucker. The assembled electric permanent magnet sucker includes a magnetic yoke, a shell, permanent magnets, reversible magnets, and magnetic pole blocks; the permanent magnets, the reversible magnets, and the magnetic pole blocks are detachably connected with the shell, and the permanent magnets, the reversible magnets, and the magnetic pole blocks are arranged in grooves of the magnet yoke. The shell is detachably connected with the permanent magnets, the reversible magnets and the magnetic pole blocks, epoxy resin is replaced bythe shell with non-ferromagnetic material which plays magnetic separation effect, the assembling ability of the electric permanent magnet sucker is realized, and replacing and maintenance are convenient; the top of the magnetic pole blocks are flush with the top of the shell, so that the surface flatness of the electric permanent magnet sucker is maintained, the deflection of the electric permanent magnet sucker is reduced, and the integral anti-compression performance of the electric permanent magnet sucker is enhanced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an assembled electric permanent magnetic chuck. Background technique [0002] The electric permanent magnetic chuck refers to the suction cup that relies on the permanent magnetic steel to generate suction, controls the suction of the magnetic steel with the excitation coil, and acts as a suction switch. The electric permanent magnetic chuck has strong suction, high safety factor, convenient operation, and energy saving. Advantages, it is widely used in forming equipment, mold processing, machinery manufacturing, lifting machinery, etc. [0003] The electric permanent magnetic chuck usually uses two different magnetic materials as the main magnet, one is the permanent magnet material with high coercive force as the main magnet, and the other is the magnetic steel material with medium coercive force as the reversible magnet. The excitation coil is fed with a pulse c...
