离心力驱动液压膨胀式高速刀柄设计
Design of Highspeed Tool Holder with Hydraulic Expansion System Driven by Centrifugal Force
摘要
Abstract
Against the centrifugal expansion mismatch of highspeed tool holder and taper hole of the spindle,a new type of highspeed tool holder was designed.It had the structure of short solid tapershank and doublesided positioning.A hydraulic elastic expansion system driven by centrifugal force was installed on the tool holder so as to compensate difference of the centrifugal expansions.The structure principle of tool holder was introduced herein.The geometrical parameters and interference were designed.The limit rotate speed and connection stiffness were analyzed by use of ANSYS.The reG search results prove that the limit rotate speed of new type of tool holder is 38% higher than that of the same specification HSK tool holder,and the radial connection stiffness is also improved to some extents,so this new type of tool holder is suitable to high speed machining.关键词
