我厂加工湿式铸铁气缸套内孔,粗铰孔是在DV406四轴镗机床上进行的,缸套定位靠定位圈和定位齿圈.在加工过程中,由于各种原因,经常出现缸套转动,使定位齿圈的局部形成像刀具上积屑瘤似的硬点,硬点高于齿圈,就无法定位了,必须换新的齿圈.由于齿圈的加工费高,制造周期长,满足不了生产需要.为此,我们设计了一种简 I plant processing wet cast iron cylinder liner bore, rough reaming hole in the DV406 four-axis boring machine, cylinder positioning positioning ring and positioning ring gear in the process, due to various reasons, often appear cylinder rotation , So that the positioning of the local formation of ring gear like a tool on the BUE like the hard point, the hard point higher than the ring gear, you can not locate, you must replace the new ring gear.As the ring gear processing fees, long manufacturing cycle, Can not meet the production needs. To this end, we designed a simple
