摘要
设计了一种调幅式轴向低频振动刀柄,分析了振动刀柄的整体结构布局及其工作原理。采用机床主轴旋转运动作为动力输入,带动正弦曲面旋转以实现振幅输出,基于两组正弦曲面相位差实现刀柄振幅调节。基于GH4169高温合金材料,运用ABAQUS有限元软件进行了三维钻削仿真试验,对比分析了GH4169高温合金在普通钻削和轴向低频振动钻削下轴向力和钻削扭矩之间的差异。结果表明:GH4169高温合金轴向低频振动钻削可以降低最大轴向力约46%,降低最大钻削扭矩约73%,可显著改善钻削条件,提高孔加工质量。
An amplitude-modulated axial low-frequency vibration tool-holder was designed,and the overall structure layout and working principle of the vibration tool-holder were analyzed.The rotation of the machine tool spindle was used as the power input to drive the sinusoidal surface to rotate to achieve amplitude output,and the amplitude of the tool-holder was adjusted based on the phase difference between the two sets of sinusoidal surfaces.Based on super alloy GH4169,a three-dimensional drilling simulation experiment was carried out using ABAQUS finite element software.The difference between the axial force and the drilling torque of super alloy GH4169 under ordinary drilling and axial low-frequency vibration drilling was compared and analyzed.The results show that super alloy GH4169 axial low-frequency vibration drilling can reduce the maximum axial force by about 46%and the maximum drilling torque by about 73%,which can significantly improve the drilling conditions and improve the quality of hole processing.
