    摘要:

    設(shè)計了一種微米級切削加工的微位移刀架，該刀架可滿足數(shù)控車床精密加工的需要。該刀架以壓電微位移致動器為動力源，以雙平行四桿柔性鉸鏈為彈性導(dǎo)軌，以最大輸出位移為主要參數(shù)，設(shè)計了微位移刀架的結(jié)構(gòu)，計算和選擇了微位移刀架的結(jié)構(gòu)參數(shù)。通過理論建模和有限元分析，對該鉸鏈機構(gòu)的系統(tǒng)剛度進行了計算，并對二維微位移刀架的輸出位移進行實驗測試。實驗結(jié)果表明：理論計算結(jié)果、有限元仿真計算結(jié)果與實驗測試數(shù)據(jù)吻合，驗證了設(shè)計方法的可行性。

    Abstract:

    The micro-displacement turret of ultra-precision CNC lathe was designed, which could meet the needs for precision machining. The power source of the turret was piezoelectric displacement actuators. The guide of the turret was double parallel four-pole flexible hinge institution. The main parameters of the turret were the maximum output displacement. The structure of micro-displacement turret was designed and calculated. The stiffness of flexible hinge institution was calculated by theoretical modeling and finite element analysis, and the output displacement of 2-D micro-displacement turret was tested. The results showed that the results theoretical calculations, finite element simulation coincided with experimental data, which could verify the reliable of the design method.
