异形滚柱的在线电解修型成型磨削工艺试验研究

介绍了一种用于汽车和摩托车上先进超越离合器异形滚柱的在线电解成型(ELID)磨削加工工艺试验及相关设备与装置,主要包括成型磨削的工艺实施方案,在平面磨床上实现成型磨削的工装设计及在线电解砂轮修型的装置设计与布局等问题。理论上分析了ELID成型磨削在加工中能按照理想的成型曲线自动修正砂轮母线的形状,从而达到很高的形状精度和较低的表面粗糙度。总结了影响加工质量和效率的因素和规律;同原来的成型拉削相比,采用成型磨削具有效率、质量与稳定性、工具成本和管理等方面的诸多优势。

Experimental Study of Online Electrolyte Shape-trimming and Forming Technique for Abnormal Roller

This paper describes the form grinding machining process of an irregular(special-shaped)roller on a new ad-vanced type of overrunning clutch,It illustrates and discusses the form grinding principle the layout of the machining schedule,the workpiece installation together with clamping,and the electrolytic in-process dress-ing(ELID)for the special-shaped grinding wheel with regard to the forming grinding carried out on a com-mon-used plain surface grinding machine.Theoretical analysis is given on how the ELID form grinding can dress the generatrix line of the cylinder grinding wheel according to the required standard curve for the workpiece with high shape accuracy and low surface roughness being gained.It also demonstrates some rules on machining roughness,profile accuracy,and material removal rate together with comparison with common form grinding by other dressing methods.Compared with the original broaching process,it posses various ad-vantages in machining efficiency,machining quality as well as stability,tool cost and management.
