摘要：偏心轴的加工效率和精度与夹具密切相关。根据三爪卡盘的结构原理对夹具结构进行优化改进，使卡盘具有调心能力，同时在卡盘中增加游标卡尺式的刻度，实现了卡盘的高精度调心。该结构设计不但解决了中心轴在同一平面内的多轴段偏心轴的加工要求，还大幅提高了偏心轴加工效率和加工精度。

Abstract:The efficiency and accuracy of machining eccentric shaft are closely related to the clamp.According to the structure principle of the three jaw chuck，the structure of the clamp is improved，so that the chuck has the ability of adjusting the center.At the same time，the vernier caliper scale is added to the chuck to realize the highprecision alignment of the chuck.The structure design not only solves the problem of machining multiaxis eccentric shaft in one plane，but also greatly improves the machining efficiency and precision of eccentric shaft.
