Processes the work piece when the engine bed, to guarantee the working accuracy, must install the work piece correctly, causes its relative engine bed cutting builder motion and the cutting tool holds the correct position, this process is called “the localization”. For because of exogenic processes and so on cutting force, force of inertia, gravity is not destroyed the work piece already the correct position which decides, but must exert certain cla hole the size precision, but must achieve the hole the position accuracy requirement. In single unit small batch production, after lineation adjusts the hole spool thread position method processing, because the drill bit rigidity bad, easy to distort, therefore the production efficiency is low, and the precision is bad. Uses the drill jig generally in the volume production, the drill jig calls the jig, through drills the set of guidance cutting tool to carry on the processing to be possible to determine accurately between the cutting tool and the work piece relative position, is the jig main feature.Key word: Machine manufacture, universal jig, unit clamp, drill jig, lathe fixture, pump body.第1章 緒論1.1機(jī)床夾具概述1.1.1機(jī)床夾具夾具是一種裝夾工件的工藝裝備，它廣泛地應(yīng)用于機(jī)械制造過程的切削加工、熱處理、裝配、文件。通過專用夾具的設(shè)計(jì)讓我了解了設(shè)計(jì)夾具時(shí)的大致過程，針對(duì)不同的機(jī)床和零件的被加工表面設(shè)計(jì)不同結(jié)構(gòu)形式的夾具。夾具由定位元件或定位裝置、夾緊元件或夾緊裝置、對(duì)刀及引導(dǎo)元件、夾具體組成、連接元件、其他元件或裝置。而本次設(shè)計(jì)是鏜床夾具的設(shè)計(jì)，根據(jù)零件外型及加工表面的位置要求選用一面兩銷定位，因此，定位元件用兩個(gè)定位銷；而夾緊元件用壓板以保證零件在鏜削力的作用下正確的位置不改變；次夾具的對(duì)刀及引導(dǎo)元件選用鏜套來保證夾具和鏜刀的相對(duì)位置；本夾具的夾具體主要是底座，用于支承零件及連接鏜套等；次夾具的主要連接元件是螺釘、銷等。在整個(gè)設(shè)計(jì)過程中遇到了很多的問題，通過各種途徑想方設(shè)法的解決。解決問題的過程中，不僅僅只解決了問題相關(guān)的知識(shí)還學(xué)到了很多。這次設(shè)計(jì)結(jié)束我不但了解到箱體類零件的工藝，還學(xué)到了整個(gè)工藝設(shè)計(jì)的方法和過程。 這次的畢業(yè)設(shè)計(jì)綜合了所學(xué)的專業(yè)知識(shí),對(duì)以后工作,特別是工藝規(guī)程和專用夾具的設(shè)計(jì)中起到相當(dāng)大的作用，對(duì)畢業(yè)生來說是一次相當(dāng)大的鍛煉。參考文獻(xiàn)1.李益民主編 機(jī)械制造工藝設(shè)計(jì)簡明手冊(cè) 機(jī)械工業(yè)出版社，19932.薛源順主編 機(jī)床夾具設(shè)計(jì) 機(jī)械工業(yè)出版社，20003.徐茂功主編 公差配合與技術(shù)測(cè)量 機(jī)械工業(yè)出版社，20004.趙如福主編 金屬機(jī)械加工工藝人員手冊(cè) 機(jī)械工業(yè)出版社，2000英文翻譯mplexity of the parts of the machining process to produce a set of protocols, according to teachers in a designated Road, processing a pair of dedicated fixture design and write a design specification. Students should be under the guidance of teachers and seriously, in a planned way, independent on time and complete the design mission. Students design their own mission must be recognized, as in a factory designed to accept the same mission, for their own technical solutions, data selection and calculation of results must be highly responsible and pay attention to combining theory and practice with a view to making the whole design is technically advanced in the the economy is reasonable, in production is feasible. The purpose of section II of the content of the curriculum design and the steps First the content of the curriculum design The course design has the following main elements: map of parts of the structural characteristics and technical requirements. according to production type and production of the proposed conditions, the structural analysis of parts and process analysis. to determine the type of rough and manufacturing methods, drawing rough plans. 2. According to the production program and the production of type, to determine the basic characteristics of craft. Program production and production type, product parts manufacturing processes, equipment and technology used in equipment for workers, technical requirements, technical measures and the required technical and economic effects will be different . 3. To determine the type of rough and manufacturing methods, drawing rough map . 4. Formulation process route . 5. The design of machining processes.
