摘要
螺旋面钻尖在钻削的稳定性和自动定心上要优于普通钻尖。研究了利用并联机构的两轴联动来实现了螺旋面钻尖刃磨的新方法,对并联机构的运动学进行研究,基于MATLAB进行了运动学和工作空间的仿真。仿真结果表明,并联机构的运动特性符合刀具刃磨所需的运动特性,且X向工作空间对参数的变化更敏感。
Hole drilling is one of the most useful methods for material machining. Helical drill point has a good performance on automatic centring and stability comparing with ordinary drill point. A new grinding method for helical drill point was provided based on 2-axis linkage of parallel mechanism. The kinematics of parallel mechanism was analyzed and the simulation of kinematics and workspace was obtained based on MATLAB. The simulation results show that the moving characteristic of parallel mechanism meet the requirement of tool grinding and X workspace is sensitive to parameter changing.
