加工中心是一种带有刀库并能自动更换刀具,对工件能够在一定的范围内进行多种加工操作的机床.本课题研究了立式加工中心国内外发展的现状,分析比较了相同类型机床的结构,着眼于本课题设计的参数及其工作状态的紧密结合.首先对加工中心进行了总体设计,随后对主轴传动方式及主轴组件进行了设计,并且对Z轴进给系统中的滚珠丝杠、轴承、伺服电机等进行了选型计算及校核,最后对刀库系统进行了结构设计和换刀时间校核等.设计结果表明本次设计基本达到工程设计的要求,具有一定的实用价值.

Answer 1

CNC is such a machine tool that contains a kind of cutter with magazine tool which can change automatically,can operate varoius manufacturingOperations in a certain range.This topic researches the developing current situation of VMC at home and abroad,analyses and compares the structure with same type of machine types,with a view to this topic which designs the close integration of the parameters and working state.Firstly,it conducts overall design for the CNC,then,it designs for the principal axis driving method and principal axis assembly,and conducts the lectotype calculation and check for the ball-screw,bearing,servo motor in the Z axis feed system,finally,it conducts the structure design and tool changing time check for the magazine tool system.The disigning result shows this design reaches the requirements of engineering design,has a definite practical value.
