摘要
采用圆弧刃光栅刻画刀具,实现在线换刃技术是解决光栅刻画刀具使用寿命问题的一种有效的途径。在线换刃圆弧光栅刻画刀具对刃口质量及精度要求高,刃磨制作工艺难度大,且国内外市场几无此类刃磨设备,需要自行设计制作圆弧刃光栅刻画刀具刃磨机床。在圆弧刃光栅刻画刀具刃磨试验设备设计制作及圆弧刃光栅刻画刀具刃磨制作工艺研究基础上,针对圆弧刃光栅刻画刀具的刃磨特点,设计新型的基于杠杆模式施载的圆弧刃光栅刻画刀具刃磨机床;根据传统机床的设计程序,对刃磨机床的功能、总体设计及详细结构设计展开研究,并对施载与微进给机构进行了振动分析,排除了出现共振的可能性。最后完成了该机床的机械装调,并刃磨制作一把圆弧刃光栅刻画刀具,其定向角∠D=63°,刀尖角∠J=90°,刃圆半径R=8.56mm,在460倍体视显微镜下观察无崩口等缺陷,刃口弧线清晰可见。刀具检测及观测结果表明,所设计的圆弧刃刀具刃磨机床适用于圆弧刃光栅刻画刀具的刃磨制作,所采用的分析及设计方法对圆弧刃刀具刃磨机床及其他机床的设计和研制具有实际指导意义。
It is an effective way to solve the problem of tool life and realize on-line edge turning technique by using arc-edge grating ruling tool in grating ruling process. Arc-edge ruling tool has a high demand for the accuracy and quality of tool edge. It is difficult to make the arc-edge grating ruling tool with on-line edge turning function, and there is barely arc-edge tool lapping machine for grating ruling at home and abroad. So above-mentioned machine needs to be developed urgently. Based on the development of lapping technique and lapping machine for arc-edge grating ruling tool, a new type of arc-edge tool lapping machine for grating ruling based on leverage load mode is designed. According to traditional machine design procedure, function analysis, overall design, and detailed structural design of the machine are studied; the vibration of micro feed system and load system is analyzed, and the resonance possibility of the machine during lapping tool process is excluded. Finally, the assembling and adjusting of the machine is finished, and an arc-edge tool is produced with designed orientation angles∠D（63°）, nose angle∠J（90°） and arc-edge radiusR（8.56 mm）. Observed by an microscope with 460-time magnification, arc edge of the above ruling tool is clearly visible, fine and clean, no chipping defects etc.. The results illustrate that the arc-edge tool lapping machine designed by this method can be used to lap arc-edge grating ruling tool. It also demonstrates that the above analysis and design method is meaningful to the design of arc-edge tool lapping machine and other machines.
