摘要

行星式研磨是在传统研磨机构的基础上，通过改变行星结构获得理想研磨轨迹，从而来提高研磨精度和效率的一种研磨方式。以实现多工件双平面同时研磨为需求，设计了对其运动轨迹做了具体分析，根据加工要求设计出具体的行星式研磨盘结构，并进一步对该研磨盘进行了运动几何学仿真以验证其可用性。这种研磨机在保证研磨加工精度和加工品质的同时，还可在一定尺寸范围内实现不同截面、多个工件的同时研磨，提高了加工效率，降低了加工成本。%The planetary lapping is an effective method for improving the precision and efficiency and the ideal grinding trajectory is obtained by changing the planetary structure on the basis of the traditional abrasive mechanism. In order to meet the needs of grind-ing double plane of multi workpieces at the same time, the specific trajectory is analyzed and then, the planetary grinding structure is designed according to the processing requirements, then, the trajectory of the lapping is simulated by the kinematics and geometry to verify its availability. The grinding machine not only has a high machining accuracy and quality, but also is used to simultaneously machine the multiple workpieces with different cross-sections within a certain size, in addition, the processing efficiency is improved greafly and the processing cost is reduced.
