我厂有一台 B2010A龙门刨床,它的原走刀机构如图1所示:当片6离开活动制子1或固定制子5时,涨紧环3便依靠本身的涨紧力和弹簧2的压力,使然紧环3紧紧地抱住摩擦轴套4并与其一起旋转,从而完成复位或进刀任务。当片6碰上活动制子1或固定制子5时,它就压缩弹簧2,因此摩擦轴套4就能在涨 I plant a B2010A planer, the original path of its knife body shown in Figure 1: When the film 6 to leave the activity of a system or a fixed system 5, the tension ring 3 will rely on their own tension and spring 2 Pressure, so that the tight ring 3 tightly clings to the friction sleeve 4 and rotates with it to complete the reset or feed task. When the sheet 6 hits the movable die 1 or the fixed die 5, it compresses the spring 2, so that the friction sleeve 4 can move up
