五轴立式加工中心进给传动部件结构设计+CAD图纸
加工中心的性能在较大程度上取决于进给传动部分的设计，因此有一个有良好的高效的进给系统是影响加工设计成败的关键之一。在详细分析了加工中心进给传动系统的设计方法和步骤后，介绍它的结构选择和刚度计算，并在验算后确保了进给系统设计的可靠性。加工中心采用立式布局，高速电动主轴通过安装插座安装在立柱导轨的滑座上，立柱导轨采用滚珠直线导轨，能够实现Z方向的进给运动。在立柱下方及上方分别安装直线导轨连接主轴滑座和机床床身，实现X、Y、Z轴直线进给运动。20215

Design of feed system on five-axis vertical machining center
Abstract：Five axis vertical machining center is a collection of a variety of functions in one of the numerical control processing equipment, a clamping workpiece can be carried out after the processing of a variety of process and more process for complex curved surface parts processing. So it has the characteristics of processing ability and excellent comprehensive performance. This paper studies the five axis feed drive system of the vertical machining center.Machining center adopts the vertical layout, high-speed motorized spindle by installing seat installed in the column on the slide guide rail, column guideway adopt ball linear guide, can realize the Z direction of the feed movement. And respectively installed above the line at the bottom of the column guide rail connects the spindle slide and machine tool lathe bed, X, Y axis linear feed movement.
It is an important fact for NC machining center to have a feed system with high performance. An integrated method of feed system on a vertical machining canter was developed. Its design method and procedure were analyzed in detail. How to choose the construction of the feed system was introduced and the rigidity of the system was vertified. The reliability of the design is ensured.
