摘要：针对三爪卡盘夹持薄壁工件时易变形的问题，介绍了一种在三爪卡盘基础上改制出原理可靠、结构简单的浮动式自定心六爪卡盘的方法，实现了改制后的卡盘在六爪联动同时能保证浮动接触、定心夹紧和稳定可靠，减少了薄壁工件夹紧变形。检测数据证明，浮动式自定心六爪卡盘能极大提高薄壁工件的加工精度。

Reform and Application of Floating Sixjaw Chuck

Zhang Fan，Tang Jun，Tian Juncheng

Abstract:Aiming at the problem that the threejaw chuck is prone to deformation when holding thinwalled work piece，a method to reform the threejaw chuck into a floating selfcentering sixjaw chuck with reliable principle and simple structur is introduced.The reformed chuck ensures floating contact，centering clamping，stability and reliability.At the same time，the deformation of thinwalled work piece is reduced.The paper also shows the test data，which proves floating selfcentering sixjaw chuck can greatly improve the processing accuracy of thinwalled work piece.
