我厂有一台M6420B滚刀磨床,由于分度操纵箱内的单向节流阀结构设计不合理,经常分度失控,不是乱分度,就是不分度。 M6420B滚刀磨床分度操纵箱是用来控制滚刀主轴分度运动的。箱体内有上下两滑阀,上滑阀是用来使闸齿从分度盘槽内脱开和插入用,并改变进入分度油缸内油流方向。下滑阀是用来控制上滑阀的换向。而单向节流阀则是调节下滑阀的移动速度和分度稳定。
I have a factory M6420B hob grinding machine, as a result of the indexing control box unidirectional throttle structure design is unreasonable, often sub-degree out of control, is not arbitrary sub-degree, that is, no degree. M6420B hob grinding machine indexing control box is used to control hob spindle indexing movement. Up and down the box inside the two slide valve, the slide valve is used to make gate gear from the index plate slot and inserted into the use, and change the direction of the oil into the indexing cylinder. Sliding valve is used to control the valve spool reversing. The one-way throttle valve is to regulate the movement speed and indexing stability.
