设计简介
摘要
数控加工中心是目前世界上产量最高、应用最广泛的数控机床之一。它的综合加工能力较强，工件一次装夹后能完成较多的加工内容，加工精度较高，就中等加工难度的批量工件，其效率是普通设备的5～10倍，特别是它能完成许多普通设备不能完成的加工，对形状较复杂，精度要求高的单件加工或中小批量多品种生产更为适用。
JCS-018型立式加工中心是一种工序高度集中，自动化程度高的机电一体化设备。工件在一次装夹后，可连续地进行铣，钻，镗，铰，攻螺纹等多种工序的加工。该机床适用于小型板件，盘件，壳体件，模具和箱体件等复杂零件的多品种，小批量加工。 主轴是主轴箱的重要组成部分。它的结构尺寸和形状、制造精度、材料及其热处理，对主轴箱的工作性能有很大的影响。为了提高主轴的刚度和便于安装，将JCS—018立式加工中心的主轴设计成阶梯圆柱形，前端外径大，后端外径小，为实现更换刀具时能自动夹紧，主轴内部设计成空心。
Z向工作台的设计主要是对滚珠丝杠和直线导轨的设计，在计算设计过程要通过刚度，扭矩和载荷等条件来选择相应的零件型号和尺寸。BF-3系统是功能比较简单的标准型数控系统。该系统采用8086微处理器芯片，8284时钟发生器，总线控制器8288，中断控制器8259，串行接口8251A，可编程计时器8253，ROM，RAM以及缓冲器，译码器等电路，此外还有一些专用芯片。

Abstract
CNC Machining Center is the world's highest yield, the most widely used one of CNC machine tools. It's comprehensive processing ability, the workpiece can be completed after a single setup process more content, higher precision, the difficulty to medium batch processing jobs, and its efficiency is the common equipment 5 to 10 times, in particular, it can be completed many common processing equipment can not be completed on more complex shapes, high precision single piece or small batch processing of many varieties produce more applicable. JCS-018 Vertical Machining Center is a highly centralized process, a high degree of automation, electromechanical integration equipment. After the workpiece in a fixture can be continuously milling, drilling, boring, reaming, tapping and other machining processes. The machine is suitable for small plates, plate pieces, shell parts, molds and complex parts such as cabinet fittings and more variety, small batch processing. Spindle is an important part of the headstock. Size and shape of its structure, manufacturing precision, material and heat treatment, the performance of the work of the headstock has a great influence. In order to improve the stiffness of the spindle and easy to install, the JCS-018 vertical machining center spindle designed to step cylindrical, large diameter front end, back-end small diameter, for the realization of the tool can automatically replace the clamp, the spindle into the interior design hollow. Z key to the design table is the design of ball screw and linear guide rail, through the design process in the calculation of stiffness, torque and load conditions to select the appropriate type and size of parts. BF-3 system is a relatively simple function of the standard CNC system. The system uses 8086 microprocessor chip, 8284 clock generator, bus controller 8288, interrupt controller 8259, serial interface 8251A, programmable timer 8253, ROM, RAM, and buffers, decoders and other circuits, in addition to There are some special chips.
