Problems solved by technology

[0002] Existing electronically controlled permanent magnet chucks, such as a chuck composed of AlNiCo magnets and rare earth NdFeB magnets, the magnetic poles of the AlNiCo magnets and the rare earth NdFeB magnets are perpendicular to each other and need to be staggered up and down , so the overall thickness of the chuck is thicker, and the magnetic circuit structure is complex, which increases the difficulty of assembly and has more magnetic flux leakage; another example is a chuck that only uses AlNiCo magnets, and the magnetic energy product of this chuck is small. Under normal circumstances, the magnetic force is weak, and the lifting requirements are usually not met, and an oscillating attenuation current is required for demagnetization, and the control is more complicated

Abstract

The invention discloses a parallel-polarity double-magnet electronically-controlled permanent magnetic chuck which comprises a shell, a magnetic pole block, reversible magnetic steel, irreversible magnetic steel, an excitation coil and isolation layers, wherein the reversible magnetic steel and the irreversible magnetic steel are arranged in the shell; the magnetic pole block is arranged on the upper sides of the reversible magnetic steel and the irreversible magnetic steel; the excitation coil surrounds the lateral parts of the reversible magnetic steel and the irreversible magnetic steel; a gap between the magnetic pole block and the shell and a gap between the excitation coil and the shell are filled with the isolation layers. In the parallel-polarity double-magnet electronically-controlled permanent magnetic chuck disclosed by the invention, the reversible magnetic steel and the irreversible magnetic steel are arranged in parallel, the problems that the overall thickness and magnetic structure of the chuck is complicated in structure and difficult to assemble are solved, and magnetic force required by the chuck during work is guaranteed while the volume of the electronically-controlled permanent magnetic chuck is reduced.

Description

technical field [0001] The invention relates to an electric-controlled permanent-magnet chuck, in particular to an electrically-controlled permanent-magnet chuck with parallel poles, and belongs to the technical field of electric-controlled permanent-magnet chuck clamping and lifting. Background technique [0002] Existing electronically controlled permanent magnet chucks, such as a chuck composed of AlNiCo magnets and rare earth NdFeB magnets, the magnetic poles of the AlNiCo magnets and the rare earth NdFeB magnets are perpendicular to each other and need to be staggered up and down , so the overall thickness of the chuck is thicker, and the magnetic circuit structure is complex, which increases the difficulty of assembly and has more magnetic flux leakage; another example is a chuck that only uses AlNiCo magnets, and the magnetic energy product of this chuck is small. Under normal circumstances, the magnetic force is weak, and it is usually unable to meet the lifting requ...
