我厂经常使用X6134型万能铣床加工模具,在加工过程中,当工作台纵向运动时,往往发现横向也移动,使工件窜动,刀具损坏,操作很不安全(据说同型号的铣床也有这种情况发生)。我们在机修时发现主要原因是:(1)由于工作油在使用一段时间后,粘度增高,使电磁离合器的靡擦片不能脱开,同时,由于机械结构上的关系(图1),电磁离合器转动带动了丝杠转动,致使工作台在纵向移动的同时引起横向移动。
I often use X6134-type universal milling machine processing mold, in the processing process, when the table longitudinal movement, often found lateral movement, the workpiece moves, tool damage, the operation is not safe (it is said that the same type of milling machine also has this The situation happens). The main reasons we found during machine repair are: (1) Due to the increased viscosity of the working oil after a period of use, the electromagnetic clutch can not be disengaged. Due to the mechanical structure (Figure 1), the electromagnetic clutch Rotation led to the rotation of the screw, causing the table to move in the longitudinal direction while causing lateral movement.
