摘 要：方滑枕類數(shù)控臥式銑鏜床因其行程較大，主軸尺寸較長，拉刀機(jī)構(gòu)安裝在主軸內(nèi)部，在松刀及主軸旋轉(zhuǎn)時，拉刀機(jī)構(gòu)會產(chǎn)生較大的變形量，對主軸產(chǎn)生較大的振動。通過靜力學(xué)分析及振動學(xué)理論將現(xiàn)有拉刀機(jī)構(gòu)進(jìn)行優(yōu)化，經(jīng)實際工程應(yīng)用證明：優(yōu)化后的拉刀機(jī)構(gòu)主軸整體性能明顯改善。

Abstract：Due to long travel and large-sized spindle of horizontal milling and boring machines， and its automatic broach mechanism installed in the spindle， the automatic broach mechanism will cause deformation amount in spindle rotating or processing， resulting in vibration to spindle. With statics analysis and vibration theory， automatic broach mechanism is optimized. Practical application verifies the remarkable improvement in the overall performance of the optimized automatic broach mechanism spindle.

Keywords：horizontal milling and boring machines；automatic broach mechanism；finite element analysis；vibration；optimization
