MAGNETIC FIELD GENERATION APPARATUS OF MAGNETORHEOLOGICAL FINISHING DEVICE

摘要

A magnetic field generation apparatus (6) of a magnetorheological finishing device, said apparatus comprising at least one electromagnetic pole set capable of producing a gradient magnetic field and consisting of two electromagnetic poles having opposing polarities, the electromagnetic poles forming the electromagnetic pole set using at least two annular magnetic poles arranged in concentric circles wherein the polarities of two adjacent magnetic poles are opposing. The apparatus (6) is used for a magnetorheological fluid to process a multi-degree of freedom movement workpiece, and with a single clamp, is capable of simultaneously performing finishing processing on outer surfaces of one or more workpieces, the outer surfaces thereof being flat surfaces, curved surfaces or complex curved surfaces. The apparatus (6) effectively solves the problem of it being difficult to finish complex curved surfaces, reduces workpiece processing procedures, and effectively increases finishing efficiency.
