钻攻零件侧孔机床的攻丝左主轴箱设计 摘 要 本文是关于钻攻零件侧孔机床的攻丝左主轴箱设计设计的说明。此机床要求在两个面同时进行自动攻丝。主要内容包括设计的必要性分析，通过对设计的机床的功能分解与功能合成以及对方案的设计从而提出新的加工方案。通过对定位方式的选择和对工件工艺性的分析以及对零件工序图、加工示意图、机床联系尺寸图和生产率计算卡，还有任务书的分析绘制主轴箱设计原始依据图确定主轴结构形式及齿轮模数，拟定主轴箱传动系统，计算主轴及传动轴坐标，设计并绘制钻攻零件侧孔机床的攻丝左主轴箱的总图及重要零件的工作图。文中对攻丝机床的通用部件及专用部件的选择都做了较为详细的说明。 关键词：组合机床；攻丝；左主轴箱 ABSTRACT This paper is about the auger attack parts of the machine tool, tapping side holes left spindle box design design instructions. This machine tools required in two sides simultaneously to be au- tomatic tapping. The main contents include the necessity of design analysis, through to the desig- n of the function of machine decomposition and synthesis and the function of the scheme design- and then puts forward new processing scheme. Through the choice of the ways of in the location- of the workpiece and the analysis of the technology of parts and working procedure chart, the pr- ocessing schemes, machine tool contact size chart and productivity calculation card, and the ana- lysis of the commitments to draw spindle box design original according to figure sure spindle str- ucture form and gear module, draws up the spindle box transmission system, the calculation of s- pindle drive shaft and coordinate, design and drawing auger attack parts of the machine tool, tap- ping side holes left spindle box the layout and important components of the working drawing. Th e general tapping machine parts and special parts option are done in a more detailed explanation. Keywords: combination machine；tools tapping ；left spindle box 目 录 绪 论 1 1 组合机床概述 2 1.1 组合机床的概念 2 1.2 组合机床的发展历史 2 1.2.1 国外组合机床的发展历史 2 1.2.2 国内组合机床的发展历史 2 1.2.3 组合机床的特点 2 2 主轴箱概述 3 2.1 主轴箱概念 3 2.1.1 通用主轴箱的组成 3 2.1.2 通用主轴箱的通用零件 3 2.2 本课题研究目的 3 3 攻丝左主轴箱设计 4 3.1 原始数据与技术条件 4 3.2 攻丝左主轴箱原始依据图 5 3.3 传动路线拟定 5 3.4 主轴箱体内各主轴的坐标计算 6 3.5 主轴及传动轴轴颈估算及校核 7 3.5.1 主轴及传动轴轴颈估算 7 3.5.2 校核中间传动轴 8 3.6 主轴及传动轴明细 8 3.7 多轴箱的传动系统设计 9 3.7.1 齿轮模数的估算及其校核 10 3.8 通用轴类零件 13 4 主轴箱总图设计 13 4.1 绘制主轴箱总图 13 4.2 主轴箱补充加工图设计 14 4.3 主轴箱的装配 14 结束语 16
