|
摘要
提出了一种基于五杆滑块机构的研磨加工新技术,并对运动部分进行结构设计,针对该技术方案的可行性进行分析。建立了平面研磨和球面研磨的数学模型,采用矩阵运算形式,得到研磨轨迹曲线方程。利用MATLAB计算,进行计算机仿真,得到不同参数匹配下的平面和球面研磨轨迹。仿真分析表明,在驱动转速和工件盘转速不成倍数关系情况下,有助于提高轨迹复杂度,降低表面粗糙度。同时,仿真结果证明了该技术方案应用于平面和球面研磨加工的可行性。
A new grinding technology based on five-bar slider mechanism is proposed,parts of movement structure are designed,and feasibility of the technical scheme is analyzed. The mathematical model for plane lapping and spherical grinding is established,and the equation of grinding trajectory curve is obtained with matrix algebra. With MATLAB calculation,the computer simulation is carried out to obtain the plane and spherical grinding trajectory under different parameters. The simulation results show that when the speed of driver and the speed of the workpiece are not multiplied,which can improve the complexity of trajectory and reduce the surface roughness. Meanwhile,the simulation results prove the feasibility of the technology scheme applied to the plane and spherical grinding process.
