缸头5个螺纹孔钻孔专机设计摘 要组合机床是由通用部件及专用部件组成的,加工一种(或几种)零件的一道(或几道)工序的高效率的专用机床, 是一种自动化或半自动化的机床.无论是机械电气或液压电气控制的都能实现自动循环、半自动化的组合机床。一般采用多轴、多刀、多工序、多面和多工位同时加工，一种工序集中的高效率机床。组合机床加工,刀具是借助钻模板和镗模架,精加工机床采用高精度的导向,所以稳定的保证产品质量。组合机床“三图一卡”就是针对具体零件，在选定的工艺和结构方案的基础上进行组合机床总体图样文件设计。其内容包括：绘制被加工零件图、加工示意图、机床联系总图、机床生产率计算卡等。机床夹具通常是指装夹工件用的装置，至于装夹各种刀具用的装置,则一般称为“辅助工具”。专用夹具在生产上起着很大的作用。机床夹具设计是工艺装备设计中的一个重要组成部分，是保证产品质量和提高劳动生产率的一项重要技术措施。通过对变速箱体零件图的分析，制定其工艺过程，确定组合机床形式，绘制三图一卡；以及对专用部件多轴箱的设计。 关键词：组合机床；多轴箱设计；夹具；加工工艺AbstractBy the combination of machine tools and parts for dedicated components, a (or several) part of a (or several road) process for the high efficiency of the machine,which is an automated or semi-automated machine tools, whether electrical machinery electrical or hydraulic control can achieve automatic cycle, the combination of semi-automatic machine. General use of multi-axis, multi-tool, multi-process, multi-faceted and multi-processing at the same time, a concentration of highly efficient processes machine. Combination of machining, tool use is based on templates and planes, finishing a high-precision oriented machine tools, stable product quality assurance. Combination machine three plans and a card is for specific parts, having an overall composition of machine design on the basis of the overall composition of machine pattern design. It contents : Drawing processed parts map, diagram processing, machine tools contact the pattern, calculating productivity machine cards.Machine tool fixture is usually used in the workpiece clamping device.As for the clamping tool used in all kinds of devices, commonly known as a tool. Fixture for the production plays an important role. Machine tool fixture design process is an important part of the design of the equipment,ensuring product quality and raising labor productivity of an important technical measures. Through the analysis of gear-box patterns, We draw up the process of its craft and determine the form of combination of machine tools, drawing three patterns and a card and the design multi-axle box of dedicated devices .Key words: Modular machine tool;Multi-axle box design;Fixtures;Processing technic目 录摘 要IIIAbstractIV目 录V1 绪论11.1本课题的研究内容和意义11.2国内外的发展概况11.3本课题应达到的要求22设计专用夹具32.1夹具的功用与组成32.2 夹具设计的基本要求32.2.1 保证工件的加工精度32.2.2 提高劳动生产率32.2.3 良好的加工使用性32.2.4 经济性好32.3 设计缸头专用夹具32.3.1 调研分析32.3.2 确定夹具设计方案42.3.3 方案审查42.3.4 绘制夹具装配图52.3.5 绘制夹具零件图53 设计组合机床63.1 组合机床工艺方案确定63.1.1 确定组合机床工艺方案的基本原则63.1.2 确定组合机床工艺方案应注意的问题73.1.3 工艺方案的拟订73.1.4 工序间余量的确定83.1.5 刀具结构的选择83.2 切削用量的确定83.2.1 组合机床切削用量选择83.2.2 确定切削力、切削转矩、切削功率和刀具耐用度83.2.4 切削力、切削转矩、切削功率83.2.5 确定主轴类型、尺寸、外伸长度93.2.6 动力部件工作循环及行程的确定103.3 组合机床总体设计“三图一卡”103.3.1 被加工零件工序图103.3.2 绘制被加工零件工序图103.3.3 零件加工工序图的绘制113.3.4 加工示意图113.3.5 机床联系尺寸图133.4 组合机床方案分析193.4.1 机床加工精度和生产率193.4.2 机床使用方便性和自动化程度193.4.3 经济性与可靠性194 设计组合机床多轴箱194.1 多轴箱的基本结构及表达式
