摘要: 对偏心运动双平面超精研抛圆柱面的加工技术进行了理论和试验研究。基于几何运动学理论建立了加工系统数学模型,应用速度矢量法求解圆柱工件各运动参数,进而实现了工件圆柱面加工轨迹的仿真,分别分析了工件中心至夹具中心距离与夹具中心至研磨盘中心距离的比值、夹具自转转速与夹具公转转速的比值对加工轨迹形态和轨迹交叉角度的影响规律。在自制试验装置上对轴承钢GCr15圆柱滚子进行了超精研磨和抛光试验,改善了一批工件圆柱面的圆度和表面粗糙度及其偏差。仿真结果和试验结果的比较分析说明,仿真结果可反映实际工件表面微观加工痕迹的相互交叉的几何特征。

Abstract: The theoretical and experimental studies were carried out on the both-side cylindrical lapping and polishing processes in eccentric rotations. The fundamental model of processing system was established based on the geometry and kinematics, and further the kinematics parameters of rolling cylindrical workpieces were obtained by the analysis of velocity vectors, next the processing trajectories on the cylindrical surface were simulated. Effects of two factors on the processing trajectories were analysed respectively, of which one factor is the ratio of distance from the center of the workpiece to the center of the fixture and the center of the fixture to the center of the grinding disc, and another factor is the ratio of clamp rotation speed and fixture revolution speed. Finally, the cylindrical rollers of bearing steel GCr15 were lapped and then polished on the self-manufactured device. The experimental results indicate that the rollers’ roundness, surface roughness and their errors are all improved. Through comparison and analysis, the simulation results may reveal and illustrate the geometric characteristics of interlaced micro cutting traces on the real cylindrical surface topography of workpieces.

Key words: kinematics, processing trajectory, both-side lapping and polishing, cylindrical surface, bearing roller
