用数控车床四工位刀架控制系统的设计001详解.doc

摘 要 数控刀架是数控机床的重要组成部分，主要是完成零件加工过程中的换刀过程，它能在一次装夹中完成多工序的加工，有效地减少了刀具多次装夹带来的加工误差。随着制造工业的不断发展，对自动刀架的功能及性能要求也越来越高。数控刀架系统本身及相关结构比较复杂，会对整机的成本造价产生直接的影响。本课题对数控车床的四工位刀架进行了研究设计。分析了刀架的基本组成、对刀架的典型结构以及刀架的机械结构等进行了研究设计，由于刀架的整个机械结构比较精密复杂，为了方便我们对刀架进行设计研究，我们对试验台上的四工位刀架进行了拆装并绘制了草图，对其主要的传动部件进行选择计算。还对刀架的电气控制部分进行分析，熟悉并掌握了四工位刀架的控制电路以及四工位刀架的控制程序。我们还对四工位刀架在工作过程中出现的几种常见故障进行分析排除。 关键字：数控刀架，机械结构，电气控制 Abstract Numbers controling the knife is the importance that counts to control tool machine to constitute part, mainly is complete spare parts to process process in of change the knife process, it can in once pack clip completion many work prefaces process, reducing knife to have many times to pack to clip to bring availably of process an error margin.Develop continuously along with the manufacture industry, request to be more and more high also to the function and function of the automatic knife.The number controls the knife the system and related structure more complicated, will build direct influence of the price creation to the cost of the whole machine.This topic logarithms controled four knifes of the lather to carry on the research design.Analyze the knife of basic constitute,to the typical model structure of the knife and the knife of the machine structure etc. carry on thorough of understanding, because of the whole machine structure comparison nicety complications of the knife, the teacher led us to carry on dismantling to pack to four knifes and draw grass diagram.The electricity part that returns to the knife carries on analysis, acquaint with and control four control electric circuits of the knifes and four control procedures of the knifes. Key word:The number controls the knife, the machine structure, electricity part 目 录 毕业设计说明书（论文） 1 绪 论 1 1.刀架总述 1 2.国内外刀架研究现状 1 第一章 刀架的机械组成 3 1.1刀架的典型结构 3 1.2四工位刀架的机械结构及工作原理 4 1.2.1数控刀架机械结构 4 1.2.2工作原理 5 1.3用途及特点 6 第二章 刀架主要部件的选用 7 2.1刀架电机的选择 7 2.2涡轮-蜗杆的选择及计算 7 2.2.1蜗杆副的设计要求 7 2.2.2蜗杆型号及材料的选择 8 2.2.3涡轮-蜗杆主要参数的计算及校核 8 2
