摘要
圆弧刃金刚石刀具制造的目标是获得刃口锋利、刀尖圆弧轮廓精度高和刃口表面质量高的金刚石刀头,其研抛工艺一直是国内外研究的热点。为提高圆弧刃金刚石刀具研抛效率和研抛质量,提出了微摆辅助机械研抛方法,理论分析表明该方法能有效提高金刚石刀具的研抛效率和研抛质量。对实现该方法的微摆幅机构进行设计和有限元模态分析,研究结果对微摆幅机构微摆频率的选择具有重要指导意义,为微摆幅机构的结构改进提供了依据。
The purpose of the arc edge diamond tool is to obtain a diamond blade with high edge sharpness,high precision of the tool nose and high surface of the cutting edge,and its polishing process has been a hot topic both at home and abroad. The method of microswing assisted mechanical polishing is put forward,in order to improve the polishing efficiency and polishing quality of the diamond cutting tool. The theoretical analysis shows that the method can improve the polishing efficiency and polishing quality of the diamond tool effectively. The design and the finite element modal analysis of the micro-swing mechanism is carried out. The results are of great significance to the selection of the micro-swing frequency of the micro-swing mechanism and provide the basis for the structural improvement of the micro-swing mechanism as well.
