超声振动深孔研磨技术研究
摘要:超声振动深孔研磨是超声振动加工技术在深孔研磨中的应用,能有效的解决普通研磨过程中加工效率低﹑材料去除率低等问题,具有普通研磨不可比拟的工艺效果。因此,研究超声振动深孔研磨技术对深孔精加工和超精加工具有重要意义。
通过理论分析和研究,建立超声振动深孔研磨磨粒运动模型并对超声振动研磨机理进行研究。对单颗磨粒附加轴向超声振动的材料去除率理论进行了分析并建立了相应的材料去除率理论模型和振动系统各传递环节的数学模型,为振动系统的振动特性分析和结构设计提供了理论依据。
研究分析了变幅杆几何尺寸,锥形心轴,以及研磨套对振动系统的影响。在分析超声振动深孔研磨机理的基础上,设计并制造了一套超声振动深孔研磨装置。
对制造完成的超声振动深孔研磨装置进行试振和调试,获得了良好的振动效果。试验结果表明整个超声振动深孔研磨装置可以进行超声振动研磨。

Research on Ultrasonic Vibration Deep-hole Lapping technology
Abstract: The ultrasonic vibration deep-hole lapping is a kind of application of the ultrasonic vibration cutting technology in deep-hole lapping, which can effectively solve the problem of low machining efficiency, low material removal rate in the general lapping process, it is superior to the general lapping in craft. Therefore, the ultrasonic vibration deep-hole lapping technology has an important sense for the deep-hole finish machining and the super finish.
Through theoretical analysis and research, the establishment of deep abrasive ultrasonic vibration and ultrasonic vibration grinding motion model to study the mechanism. Single grain of additional axial ultrasonic vibration theory of material removal rate were analyzed and the corresponding theoretical model of material removal rate. Transmit link's mathematical model respectively about the every parts of the vibrating system was established, it provides the theoretical basis with the vibrating system's vibratory characteristic analysis and the structural design.
Analysis of the horn geometry, conical mandrel, and the ground cover’ effect on the vibration system. Based on the analysis of the ultrasonic vibration deep-hole lapping, lots of theoretical analysis. In addition, a ultrasonic vibration deep-hole lapping in stallment was designed and manufactured.
