摘　　要：近年来,根据增减材技术的发展趋势,需要在同一台数控机床上实现增减材功能。设计了一套复合滑枕结构实现3D打印头和机加工头的高效组合集成。先通过3D打印技术的增材功能实现工件成形过程,再通过机械加工技术进行指定部位的切削加工,从而实现预定工件的一站式成形加工功能。将本结构设计方案在某增减材复合功能龙门机床上进行了实际应用验证,极大减少了生产过程中工件的搬运工作,并避免了多次定位装夹造成的工件装夹误差。验证结果表明,本方案结构设计合理,尤其对于具有大中型部件的机床设备,不仅极大地精简了设备的结构复杂度,降低了设备的直接材料投入,而且提高了产品的整体可靠度、使用效率和性价比。In recent years,according to the development trend of material adding and subtracting technology,it is necessary to realize the material adding and subtracting function on the same CNC machine tool.A set of composite ram structure is designed to realize the efficient combination and integration of the 3D printing head and the machining head.The forming function of the workpiece is realized through the additive function of 3D printing technology,and then the designated part is processed through the machining technology,thus realizing the one-stop forming and processing function of the predetermined workpiece.This structural design has been verified by practical application on a gantry machine tool with compound functions of adding and subtracting materials,which greatly reduces the handling of workpieces in the production process and avoids the workpiece clamping deviation caused by multiple positioning and clamping.The results show that the structural design is reasonable,especially for machine tools with large and medium-sized components.This structure greatly simplifies the structural complexity of the equipment,reduces the direct material investment of the equipment,but also increases the overall reliability,efficiency and price-performance ratio of the products.
