摘 要
本文是关于立式加工中心床身系统结构设计及排屑系统结构设计,分为两大部分主要内容。
第一部分主要介绍床身系统。主要从床身基本形式的确定到床身材料的选择和处理,对床身进行了结构方面的设计及计算,并利用CATIA软件对床身受力、变形等方面进行了有限元分析,对设计结果进行校验。
第二部分主要介绍排屑系统。排屑装置是以电机带动链轮,链轮牵引链板在排屑机箱体中做回转运动,加工中心加工过程中产生的切屑落到链板上,由链板运输到立式加工中心外落入排屑车中。进而实现了对立式加工中心在加工过程中产生切屑的运送、收集和对切屑进行进一步处理的能力。
另外,本文也对数控立式加工中心以及床身系统和排屑装置的发展现状及趋势进行了相应的阐述。

Abstract
This article is a design manual that mainly about the vertical CNC machining canter’s bed system and chip-removal system,and it can be divided into two parts。
The first part mainly talk about the Bed system,working on the structural design and the calculations。Meanwhile,use CATIA to do some finite element analysis(FEA)about the stress and displacement in order to verify the design results。
The second part mainly talk about the Chip-removal system。Device of chip-removal work in the box through scroll wheel dragging the transporting steel plate the traction conveyor chain plate,the scraps which processed in the operation of the machining center can fall to the chain belt,transported out of the machine by a chain belt and then fall into the litter box。This system can be used for the collection,transportation and further processing。
In addition, this article also talks about the development of CNC Vertical machining center and bed system and chip-removal system.
