一种版辊堵头锥孔内键槽拉削装置
本技术属于版辊加工设备
,具体是一种版辊堵头锥孔内键槽拉削装置。
技术介绍
申请号为201420733567.5的专利公开了一种凹印版辊堵头锥孔内键槽拉削装置,包括卧式拉床、成型拉刀;在卧式拉床上安装有用于夹紧凹印版辊堵头的固定夹具和移动夹具,固定夹具和移动夹具的夹紧面相互平行,拉刀依次穿过移动夹具、凹印版辊堵头和固定夹具与拉床的拉杆相连。使用时通过固定夹具和移动夹具夹持多个堵头,再通过拉刀加工键槽,从而提高了加工效率。然而此种拉削装置还存在以下不足:1、拉刀加工时会产生切屑,而拉刀的切削刃在其轴向上形成为多段,因此卷曲的切屑容易附着在切削刃上或切削刃之间的刃槽内,则拉刀在下次的加工时,无法形成正确的槽,甚至损伤切削刃或工件的加工面,影响加工质量;2、堵头上键槽的深度随着堵头直径变化,导致加工不同直径堵头的键槽需要更换不同的拉刀,导致加工成本较高,而换刀的过程也降低了生产效率;3、拉刀在加工时的刚度较差,容易导致在加工过程中拉刀位置发生偏移,进而影响键槽的加工质量。
