稀土永磁磁力研磨机进给系统需要解决的主要问题是磁性磨料换向 ,本设计通过力封闭的对心直动滚子推杆盘形凸轮机构、螺旋压缩弹簧机构带动研磨头作间歇来回往复运动产生一个变化的磁场 ,有效地解决了磁性磨料换向问题 ,极大地提高了加工效率及工件表面质量 The main problem to be solved in the feeding system of rare earth permanent magnetism magnetic mill is the reversing of the magnetic abrasive, which is driven by intermittent reciprocating back and forth driven by the helical compression spring mechanism through the closed-center direct-acting linear roller thrusting disc cam mechanism Movement to produce a changing magnetic field, effectively solve the magnetic abrasive commutation problem, which greatly improves the processing efficiency and surface quality of the workpiece
