摘要

为得到热缩刀杆与刀具配合公差与其最小装夹温度之间的精确关系,对影响刀杆接触面最小热位移差值的感应加热长度、热缩刀杆壁厚、锥角、配合长度、内径等因素进行了研究。采用ANSYS参数化设计语言,构建具有过盈特征的刀杆与刀具配合的参数化有限元模型,通过试验验证了模型的可靠性。通过获取热缩刀杆接触面的位移分布,结合刀杆与刀具接触状态的表征方法对接触面上最小热位移差值进行了计算。计算结果表明,配合面最小热位移差值随着热缩刀杆壁厚、配合长度、锥角的增加而减小,随着内径的增大而增大,且适当增大感应加热长度也有利于刀具的装夹。最终建立了配合公差所对应的过盈量?与最小装夹温度T之间的计算关系式,对刀具在热缩刀杆中的装夹及刀杆的结构设计提供理论指导。

Abstract

A research of the length of induction heating, shrink-fit tool holder thickness, cone angle, length of fit and inner diameter etc. for the influence of minimum contact surface displacement difference with the holder to find the exact relationship between tolerance and minimum clamping temperature. The interference characteristics of holder and tool with the parameterized finite element model by ANSYS parametric design language and verified by experiment for the reliability of the model is built. The minimum displacement difference is calculated by getting the displacement distribution of the contact surface on tool holder with the combination of characterization methods between holder and tool contact status. Calculations indicated that the minimum thermal displacement difference of the fitting surface will decrease with the increase of holder thickness, length of fit, cone angle; it will increase with the inner diameter increasing, and it is good for the clamping if increase the length of induction heating appropriately. Finally, we established the calculating formula between interferencef and the minimum clamping temperature T, it has a practical guiding significance for the clamping process of the cutting tool and the design of the holder.
