銑床用組合夾具設計

　　　　　　　　　　　　　　　　　摘 要
　　　夾具是能夠使產(chǎn)品按一定的技術要求準確定位和牢固夾緊的工藝裝置，它的主要用于保證產(chǎn)品的加工質(zhì)量、減輕勞動強度、輔助產(chǎn)品檢測、展示、運輸?shù)取］S類工件是常見的工程結構，提高軸類工件銑床夾具設計效率有實際工程意義。
　　　目前，世界上許多國家在計算機輔助夾具設計方面，都做了大量工作。我國在該項領域中尚處于研究階段。計算機輔助夾具設計是通過計算機軟件程序來完成夾具結構設計、總裝圖和零件圖的繪制，以及制定出夾具零件的制造工藝等主要工作的計算機輔助機械設計的一個分支。傳統(tǒng)的機床夾具設計需要檢索許多資料，并花費許多繪圖時間，設計的效率低、成本高。機床夾具設計往往還需借助于設計者的經(jīng)驗。計算機輔助夾具設計的開發(fā)和應用，既可縮短設計周期，又能促進機床夾具的標準化和系列化。
　　　在計算機輔助夾具設計中，主要分為組合夾具和專用夾具設計二類。而國際上主要研究的對象是采用標準元件的槽系和孔系的組合夾具。當前國外正向開發(fā)夾具柔性化系統(tǒng)領域努力。夾具柔性化主要表現(xiàn)在以下兩方面：一是結構的柔性化，即廣泛采用標準元件的槽系和孔系組合夾具。二是夾具設計過程柔性化，也就是利用計算機技術和人工智能，把工程師設計夾具的過程描述為一個軟件系統(tǒng)。

Abstract
　　　Fixture is to make the products according to certain technical requirements for accurate positioning and firm clamping of the process device, its main products for processing to ensure quality, reduce labor intensity, support product testing, display and transportation. Shaft parts is a common project structure and improve the efficiency of shaft parts milling fixture design of practical engineering significance.
　　　Currently, many countries in the computer-aided fixture design, has done a great job. China in the field research stage. Computer-aided fixture design by computer software applications to do Fixture Design, assembly Tu and mapping components, and fixture parts to develop manufacturing processes and other major work in a branch of computer aided mechanical design. The traditional design of jigs and fixtures need to retrieve a lot of information, and spend too much time drawing and design of low efficiency and high cost. Tool fixture design often need the help of the designer's experience. Computer-aided fixture design development and application, can shorten the design cycle, but also to promote the standardization and serialization of jigs and fixtures.
　　　In the computer-aided fixture design, divided into modular fixture and special fixture design Type II. The major international study of the object is a standard component of the tank system and a combination of fixture holes. The current positive development of foreign systems in the field of flexible work fixture. Fixture flexibility lies in the following two aspects: First, the flexible structure, wide range of standard components that slot modular fixture system and holes. Second, the flexible fixture design process, that is using computer technology and artificial intelligence, to engineer the design process is described as a fixture of the software system.
