摘要：加工中心是一种综合加工能力较强的数控加工设备，本文研制的五轴立式加工中心集多种加工功能于一身，工件一次装夹后能对各类小型复杂零件进行多种工序加工，并且能五轴联动进行复杂曲面的加工。经过对不同运动方案和各部件的设计方案的定性分析比较确定该加工中心的总体设计方案为:采用立式布局，高速电主轴通过安装座安装在立柱导轨的滑座上，立柱导轨采用滚珠直线导轨，可以实现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轴直线进给运动。在床身工作台上安装摇篮式旋转工作台，实现A、C轴旋转进给运动。五个运动自由度均由高精度滚珠丝杠及旋转工作台配合交流伺服电机进行控制，实现精确的五轴联动加工控制。与目前国内同类型加工中心比较，具有结构紧凑、空间尺寸小、加工精度高、生产效率高等优点。7385

The overall arrangement and main spindle part design for five-axis vertical machining center
Abstract：The five axis vertical machining center is one kind of synthesis machining ability strong numerical control machining equipment, the five axis vertical machining center collect a variety of machining function at a suit, work piece after a fixture of all kinds of small complex components can perform a variety of machining and five-axis complex surface machining. Passes through quite is definite this education small vertical processing center to the different movement plan and various parts design proposal qualitative analysis the overall project design is using the vertical layout, the main spindle part installs through the installment place in on the column guide rail slide rails, the column guide rail uses the trundle guide rail, may realize the Z direction feed motion. Were installed in the column below and above the linear guide connected to the the spindle slide and machine bed, to achieve X,Y axis linear feed motion. Install the cradle rotary table on the workbench, to achieve A , C -axis rotary feed motion . Five degrees of freedom of movement are controlled by the high - precision ball screw and rotary table with AC servo motor, and accurate five-axis machining control. Compares with the present domestic same type processing center, has the structure compact, the spatial size small, the processing precision high, the production efficiency higher merit.
