GSHM7060四轴联动卧式加工中心的研制

Study of GSHM7060 4-axis Linkage Horizontal Machining Center

卧式加工中心是一种高效、高性能的数控机床,在一次装夹中可进行四个面的铣削、钻孔、扩孔、镗孔、铰削、攻丝等多种工序的加工,最适用于中、小批量、多品种的箱体零件以及曲型零件的加工。本文介绍了一种四轴联动卧式加工中心的机械结构、特点及其关键技术,通过建立高速加工中心机床的三维有限元模型,利用有限元分析软件对机床进行动力学分析,找出影响整机动态性能的薄弱环节并提出结构设计修改方向,从而使机床具有更好的静态、动态特性。

Horizontal machining center is high efficiency and high performance NC machine. After clipping once, the machining center can process many working procedures for example milling, drilling, boring, reaming, tap on four surfaces of parts, and fits for middle and small batch, much variety, box and bending parts. The paper introduces mechanical structure, characteristic and key technology of a kind of 4-axis linkage horizontal machining center. Through establishing 3D FEA model of high-speed machining center, the paper uses FEA software to process machine dynamics analysis, finds out weak link of influencing whole machine, and brings forward structure design modifying direction. So the machine can have better static and dynamic characteristic.
