摘　　要：研磨机是超精密加工机器中不可或缺的加工机器,伴随着工业化的发展,研磨工艺成为工业生产上必不可少的一部分。以多自由度五杆机构为基础,提出了RRPRR型五杆机构,针对RRPRR型五杆机构进行运动轨迹仿真分析,对该结构中滑块的摆角进行了分析,判断了其存在急转特性,使研磨机的稳定性进一步提升,参数的调整对提高RRPRR五杆机构研磨机的研磨效率具有积极作用,显著地降低了机器制造成本,保证了球副研磨机的加工精度、质量。RRPRR型五杆机构研磨机可同时适应于平面副和球面副研磨,使研磨技术进一步实用化。Grinding machines are indispensable processing machines in ultra-precision processing machines.With the development of industrialization,the grinding process has become an indispensable part of industrial production.Based on the multi-de-gree-of-freedom five-bar mechanism,the RRPRR five-bar mechanism is proposed.The RRPRR five-bar mechanism is used to simulate the motion trajectory.The swing angle of the slider in the structure is analyzed and the sharp-turn characteristics are judged.The stability of the grinder is further improved,and the adjustment of the parameters has a positive effect on improving the grinding efficiency of the RRPRR five-bar mechanism grinder,which significantly reduces the machine manufacturing cost and ensures the processing precision and quality of the ball sub-grinding machine.The RRPRR five-bar mechanism grinder can be adapted to both the plane pair and the spherical sub-grinding,making the grinding technology further practical.
