机床夹具课程设计
机械制造工艺学课程设计说明书
V形座工艺过程设计
绪论
机械加工工艺课程设计是自己学完了机械制造及相关模具课程后,对机械加工工艺过程、机械加工工艺和机床夹具结构进一步了解的实践性的教学环节,是学习深化与升华的重要过程,是对自己综合素质与工程实践的能力培养。
在教师的指导下独立完成一项给定的设计任务,编写符合要求的设计说明书,并正确绘制有关图表。
在课程设计工作中,我们应综合运用多学科的理论、知识与技能,分析及解决设计问题。
通过本次课程设计,我们应学会依据技术课题任务,进行资料的调研、收集、加工与整理和正确使用工具书;培养自己掌握有关工程设计的程序、方法与技术规范,提高工程设计计算、图纸绘制、编写技术文件的能力;培养自己掌握实验、测试等科学研究的基本方法;锻炼自己分析与解决工程实际问题的能力。
通过课程设计,希望自己能树立正确的设计思想;培养自己严肃认真的科学态度和严谨求实的工作作风;在工作设计中,应能树立正确的工程意识与经济意识,树立正确的生产观点、经济观点与全局观点
该课程设计是学完本专业课程之后的一项重要的实践,是我们步入社会的一次深刻的链接,考察了我们独立设计,计算,绘图和分析的能力,同时提高了我们查阅各种设计手册的能力,通过该课程设计我们了解了夹具设计的一般步骤,需要用到的一些结构都需要我们认真查阅后绘制到图纸上,通过课程设计我们学会了很多课本上没有的知识。

一、零件的分析
(一)零件作用
题目所给零件V形座是用于支承轴、管、套筒等圆柱形工件,使工件轴心线平行于平台工作面,并方便找正和划线的工具。
(二)零件的工艺分析
零件的结构:
该零件结构简单、对称;表面光度要求高。
零件主要有以A面,B面和V形面主要加工表面。
这3个面的要求精度高,端面粗糙度在Ra0.1um。
V形面的尺寸基准是以A面和B面为基准。
主要技术要求:
1.A面与?
150圆柱册母线不平行度误差0.003。
2.B面与?
150圆柱上母线不平行度误差0.003。
3.90?
两面全长不垂直度允差0.01与30两侧面不垂直允差0.01。
4.45?
半角不对称允差0.01/100;热处理:
淬火45~50HRC。
二.工艺规程设计
(一)确定毛坯的制造形式
零件的材料为铸铁,要求有一定的强度要求,轮廓尺寸不大,且形状亦不太复杂,做毛坯可采用铸造成型。
毛坯尺寸、形状的确定:
A模具零件毛坯应考虑为模具加工提供方便应尽可能根据所需的尺寸确定毛坯,以免浪费加工工时,增加模具成本。
B确定毛坯尺寸还应考虑毛坯在制造过程生产的各种缺陷(如裂纹、脱碳层、氧化皮等),在加工时必须完全去除以免影响模具的质量。
C毛坯形状应尽可能与模具零件形状一致,以减少机械加工的工作量。
综上所述:
毛坯尺寸确定为180×204×117(mm)
(二)基准的选择
基面的选择是工艺规程设计中的重要工作之一。
基面选择正确、合理,可以保证加工质量,提高生产率。
否则会使加工过程出现许多问题,产生废品,使生产无法进行。
