摘要
针对超声辅助超精研磨陶瓷滚子的技术需求,基于简谐振动基本原理和波动方程,设计了超声振动的阶梯形超声变幅杆,研发了适用于陶瓷滚子超精加工试验机的点接触式超声振动辅助装置。利用试验机,研究了超声电源电流对陶瓷滚子表面粗糙度和材料去除率的影响规律,并进行了超声加工超精研磨影响对比试验。结果表明:文中所研发的超声振动装置安装简便,工作可靠;与普通超精加工相比,超声复合加工在改善工件表面质量的同时,加工效率有显著提升。
Considering that the technical requirements of ultrasonic assisted superfine grinding ceramic roller, based on the basic principle of simple harmonic vibration and wave equation,a stepped ultrasonic horn of ultrasonic vibration was designed,and the point contact suitable for ceramic roller super finishing machine was developed. Ultrasonic vibration aids. Using the testing machine,super-finishing test was carried out in different ultrasonic power supply currents to investigate the influence of different ultrasonic power supply currents on the surface roughness and material removal rate of ceramic rollers. The ultrasonic welding super-fine grinding effect comparison test was carried out. The results show that compared with ordinary super-finishing,ultrasonic composite machining improves the surface quality of the workpiece and the processing efficiency is significantly improved.
