摘要
活塞环内外圆轮廓是一种不规则的自由型线,切削加工困难,通常所用的仿形靠模车床存在加工效率低、调整周期长、易于磨损等缺陷。在分析活塞环切削加工特点的基础上,应用直线伺服电机研制开发了一台高速响应活塞环数控车床,并对该机床研制中的关键技术,如活塞环开口过渡曲线拟合、快速响应刀具进给系统研制、机床总体结构设计、活塞环CAD/CAM软件模块开发等进行了阐述。
The outline of the piston ring is a kind of irregular curve. It is difficult to machining. The lather used for general profile modeling has many disadvantages, such as low efficiency, long adjustment period and so on. The paper analyzes the characteristics of the piston ring machining,developes a new type of piston ring CNC lather used for high speed response. It depicts the optimization of transition-curve, feed-drive system, the total layout structure.
