河南理工大學(xué)本科畢業(yè)設(shè)計(jì)（論文）
摘要
二十一世紀(jì)的制造業(yè)面臨著顧客需求驅(qū)動(dòng)、不可預(yù)測(cè)、快速多變和來(lái)自全球不斷增加的市場(chǎng)競(jìng)爭(zhēng)，而且競(jìng)爭(zhēng)不斷加劇。市場(chǎng)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(chǎng)需求。近來(lái)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(guó)國(guó)情。作為制造系統(tǒng)重要組成部分的夾具設(shè)計(jì)部分，制造系統(tǒng)對(duì)其提出了新的要求。夾具在機(jī)械加工起著重要的作用，它直接影響著機(jī)械加工的質(zhì)量，生產(chǎn)效率和成本，因此夾具設(shè)計(jì)是機(jī)械工藝準(zhǔn)備和施工中的一項(xiàng)重要工作。
這篇畢業(yè)設(shè)計(jì)主要闡述的是一套關(guān)于電機(jī)座液壓夾緊粗鏜夾具的設(shè)計(jì)方法，這種夾具主要應(yīng)用于電機(jī)座的粗鏜工序，通過(guò)這個(gè)夾具可以保證電機(jī)座粗鏜后的加工要求和達(dá)到提高生產(chǎn)效率的目的。
在說(shuō)明書(shū)中，首先明確了設(shè)計(jì)任務(wù)并對(duì)夾具作了相關(guān)的闡述，接著根據(jù)電機(jī)座的加工工序提出了鏜床夾具的設(shè)計(jì)方法和理論，并依據(jù)這些方法和理論對(duì)夾具進(jìn)行設(shè)計(jì)和校核、驗(yàn)算。最后對(duì)夾具中某些典型或重要的零件進(jìn)行了介紹和校核。這種設(shè)計(jì)方法代表了鏜模的一般設(shè)計(jì)過(guò)程，對(duì)其他夾具的設(shè)計(jì)工作也有一定的價(jià)值。
關(guān)鍵詞：夾具、電機(jī)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.
