磨削曲轴的快速分度定位系统设计

摘要

The crankshaft is very important in the automobile engine parts,but because of its unique structure,it is very difficult to process,multi cylinder crankshaft grinding has high requirements on the accuracy and stability of indexing positioning system.According to these characteristics,a rapid indexing and positioning system for MKS8260 CNC Crankshaft Grinder is developed and manufactured.In this paper,the structure and working principle of the fast indexing and positioning system of the crankshaft connecting rod neck are described in detail,and the reliability of each part is analyzed by finite element analysis software.%曲轴是汽车发动机中很重要的零件,但由于其结构的特殊性,却非常难以加工,多缸曲轴连杆颈的磨削对分度定位系统的精度、稳定性有很高的要求.根据这些特点,研制和生产了用于MKS8260数控曲轴磨床的快速分度定位系统.详细阐述了这种曲轴连杆颈的快速分度定位系统的结构与工作原理,通过有限元分析软件分析了各零件的工作可靠性并已在实际生产中成功应用.
