機床夾具的設計
           

摘  要
這次專業(yè)設計是專業(yè)的一個十分重要的學習環(huán)節(jié)，是對入學以來所學的機械方面的知識進行了一次全面的檢查、鞏固和提高。這次課程設計是應用所學基礎理論、專業(yè)知識與技能去分析和解決生產(chǎn)實際問題的一次綜合訓練。把所學的知識能夠綜合運用到實際零件的加工中。通過本次設計使我鞏固了已學的知識，加深了印象，使自己能夠運用所學的機械加工知識解決一些具體的問題。
此次課程設計涉及的知識面有夾具設計、零件安裝、加工工藝、數(shù)值計算、刀具的性能、測量技術、CAD制圖外還涉及到金屬材料、公差配合及加工設備等多方面的知識。通過這次課程設計我發(fā)現(xiàn)了自己還有許多知識還沒有掌握牢固。但更多的是通過這次設計使我提高、鞏固、擴大了自己所學到的理論知識與技能，提高自己設計計算、制圖、編寫技術文件的能力‘學會正確使用技術資料、標準、手冊等工具書’并在這次設計中培養(yǎng)了我對機械設計的獨立工作能力、初步樹立了正確的實際思想，掌握了一定的機械加工設計方法步驟和思路為以后的學習和設計工作打下了良好的基礎。同時，也使我體會到了老師平時對我們的諄諄教導、用心良苦。由于本人水平有限，設計還有許多不足之處，希望時老師給予批評和指正！

ABSTRACT
The professional design is one of the important link of the study, it is learned since admission knowledge of mechanical conducted a comprehensive examination, consolidate and enhance. This course is designed to apply their basic theory and specialty knowledge and skills to analyze and solve practical problems of production. Combine the knowledge to use to the actual machining. Through the design that I have learned knowledge consolidated, deepen the impression, make oneself can use some specific knowledge of mechanical processing.
This course design involves knowledge have clamp design, installation, processing, parts of numerical calculation, tools and measuring technology, the properties of the CAD drawing was involved in metal materials, tolerance and processing equipment, etc.Through this course design, I found the oneself still have many knowledge has not mastered the firm. But more and more are through this design makes me improve, consolidate and expand their knowledge to the theoretical knowledge and skills, improve their design calculation, drawings, writing ability of technical documents to correctly use the technical data ", standard, manual tool in the design of "and I trained on mechanical design of the ability to work independently, set up the correct actual preliminary thoughts, grasped certain mechanical processing design methods and steps for the future study and design work, and laid a good foundation. At the same time, also make me realize teacher usually teach in our earnestly, good intentions.Because of my limited, design has many shortcomings, hope the teacher give criticism and correct!
KEYWORDS
