摘　　要：在链轨节密封圈沉孔的镗孔加工过程中存在断屑困难以及切屑缠绕刀杆的问题。为了解决切屑缠绕刀杆的问题,从工件材料、结构及刀杆结构等方面对该问题进行分析,设计了一种基于工件间歇进给原理的断屑方法,设计了不同间歇进给次数的加工程序并进行了试验。试验结果表明,当工件的间歇进给次数达到8次及以上时,可解决切屑缠绕刀杆问题。In the boring process of the seal countersink of the track link,it is difficult to break the chip and the chip winds around the cutter bar.In order to solve the problem of chip winding,the problem from the aspects of workpiece material,structure and tool bar structure is analyzed,and then a chip breaking method of intermittent feed is designed.The processing programs with different intermittent feed times are designed and experiments are carried out.The experimental results show that when the intermittent feeding times of the workpiece reach more than 8 times,the problem of chip winding around the cutter bar can be solved.
