摘要
方滑枕类数控卧式铣镗床因其行程较大,主轴尺寸较长,拉刀机构安装在主轴内部,在松刀及主轴旋转时,拉刀机构会产生较大的变形量,对主轴产生较大的振动。通过静力学分析及振动学理论将现有拉刀机构进行优化,经实际工程应用证明:优化后的拉刀机构主轴整体性能明显改善。
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.
