河南理工大學本科畢業(yè)設計（論文）
摘要
二十一世紀的制造業(yè)面臨著顧客需求驅(qū)動、不可預測、快速多變和來自全球不斷增加的市場競爭，而且競爭不斷加劇。市場的不斷變化要求制造系統(tǒng)加工的產(chǎn)品品種能夠快速變換以滿足市場需求。近來的制造業(yè)發(fā)展表明，夾具能比較好的滿足上述要求并符合我國國情。作為制造系統(tǒng)重要組成部分的夾具設計部分，制造系統(tǒng)對其提出了新的要求。夾具在機械加工起著重要的作用，它直接影響著機械加工的質(zhì)量，生產(chǎn)效率和成本，因此夾具設計是機械工藝準備和施工中的一項重要工作。
這篇畢業(yè)設計主要闡述的是一套關于電機座液壓夾緊粗鏜夾具的設計方法，這種夾具主要應用于電機座的粗鏜工序，通過這個夾具可以保證電機座粗鏜后的加工要求和達到提高生產(chǎn)效率的目的。
在說明書中，首先明確了設計任務并對夾具作了相關的闡述，接著根據(jù)電機座的加工工序提出了鏜床夾具的設計方法和理論，并依據(jù)這些方法和理論對夾具進行設計和校核、驗算。最后對夾具中某些典型或重要的零件進行了介紹和校核。這種設計方法代表了鏜模的一般設計過程，對其他夾具的設計工作也有一定的價值。
關鍵詞：夾具、電機座、工序
Abstract
Manufacturing companies in the 21s' century will face unpredictable, high-frequency market changes driven by global competition. The continuous changes of market require a rapid change of product varieties in order to meet the market demands. Recent surveys have showed that fixture are the cornerstones of this new manufacturing paradigm. Fixture is also suitable to our country. After reconfiguration manufacturing system puts new requirements on fixture design, an important component of the traditional manufacturing system. Fixture is very important equipment in process of machine manufacturing because it can directly affect the quality of products and productivity and cost. So fixture designing is also a base portion in machine process.
This paper of graduation mainly presents a systematic approach for the design of Electrical Block hydraulic upholding tool rough noise of drums .this upholding tool are mainly used in the working procedure of Electrical Block hydraulic rough noise of drums . It can accomplished the purpose what this fixture can be satisfy after Electrical Block hydraulic upholding tool rough noise of drums produce demand and approach to improve production efficiency.
First ,we define the design of assignment and represent something about fixture. The next ,Accordingly to the processing of workpiece of motor cabinet ,we extract the method and way of boring lathe of fixture. And then ,we practice into design the fixture according to the method and way .After this design ,we take some canonical workpiece for example to check the strength.. The method of this fixture represent the process of canonical fixture. Of course ,the design of our fixture also can guide the design of fixture.
