X6132铣床的夹具设计 摘 要 机械结构设计能力是从事机械制造专业的科研、工程技术人员必须具备的基本素质之一。机床夹具设计作为高等工科院校教学的基本尊连科目，在实践中占有极其重要的位置；夹具结构设计在加深对专业课程基本理论的理解和加强对解决工程实际问题的能力的培养方面所发挥的作用是显而易见的；机床夹具又是保证机械产品质量高、数量多、成本低的一种重要的工艺装备，夹具设计和制造的工作量就显得更为突出，因此中小型零件加工的专用夹具常被选作毕业设计的主要内容之一。本次的设计任务为铣床夹具。对于夹具设计来说，参考现有机床结构是极其重要的一环，这次设计的主要尺寸都是围绕X6132卧式铣床进行的。 关键词：液压系统、专用夹具、卧式铣床。 Abstract The abstract mechanism congratulating machine ability is engaged in one of basic qualities which the machine manufacture specialized scientific research, the engineers and technicians must have. The engine bed jig design took the higher engineering course colleges and universities teaching basically reveres continually the subject,Holds the extremely important position in the practice; The jig structural design is deepening to the specialized curriculum elementary theory understanding and strengthens to solves the function which the project actual problem ability raise aspect displays is obvious；The engine bed jig also is the guarantee mechanical product quality high, the quantity are many, the cost low one kind of important craft equipment，the jig design and the manufacture work load appears prominently，therefore the middle and small scale components processing unit clamp often chooses to do one of graduation project main contents。This design duty for milling jig，designs regarding the jig said，refers to the existing engine bed structure is an extremely important link，this design main dimension all is revolves the X6132 horizontal milling machine to carry on. Key words: hydraulic system, unit clamp, Horizontal milling machine. 目 录 1 绪 论 ………………………………………………………………………………1 2 原始资料以及工件工艺分析 …………………………………………………… 3 2.1原始资料的分析…………………………………………………………………… 3 2.2工件的工艺分析 ………………………………………………………………… 4 3 夹具元件和液压系统设计 ……………………………………………………… 5 3.1确定定位方案，设计定位元件…………………………………………………… 5 3.2定位元件的设计…………………………………………………………………… 5 3.2.1固定V形块设计……………………………………………………………… 5 3.2.2定位板的设计………………………………………………………………… 6 3.2.3 定位误差分析……………………………………………………………… 7 3.3夹紧方式的
