中型数控机床防护轻量化设计

Lightweight Design for Protection of Medium-sized CNC Machine Tool

数控机床轻量化设计是实行绿色制造的一条有效途径,机床防护是机床的一个功能部件,也应该进行轻量化设计。为探寻中型数控机床防护轻量化的一种有效途径,文中采取有限元静力分析的方法,选择一款量产数控机床防护的一扇维修门作为研究对象,通过对同结构不同板厚强度、同结构不同形式加强筋的比较,优选出最佳防护结构设计方案。优选出来的最佳设计方案不仅比实际量产的方案质量明显减轻,而且在强度方面也有所提升,证实了文中采取途径的可行性与有效性。

The lightweight design of CNC machine tool is an effective way to pursue green manufacturing.The machine tool shield is a functional part of machine tool,and the lightweight design should also be implemented.This paper uses finite element analysis method to find an effective way for the lightweight of medium-sized CNC machine tool.The maintenance shield door of a mass-produced CNC machine tool is selected as the research object.By comparing the strength of different plate thickness with the same structure and the stiffeners of different forms with the same structure,the optimal design scheme of protective structure is selected.The optimal design scheme is not only significantly lighter than the actual mass production scheme,but also the strength of the machine tool shield is improved,which substantiates the feasibility and effectiveness of the adopted approach in this paper.
