【正文】 夾具低的多，相信在不久的將來(lái)氣動(dòng)行業(yè)必定超過(guò)液壓。氣密性試驗(yàn)對(duì)于大規(guī)模生產(chǎn)的企業(yè)來(lái)說(shuō)，生產(chǎn)效率也是極其重要的。開(kāi)環(huán)控制，控制精度不是很高。在電空制動(dòng)系統(tǒng)中最重要的是電、空轉(zhuǎn)換技術(shù)。介質(zhì)毒性程度為極度、高度危害或設(shè)計(jì)上不允許有微量泄漏的壓力容器，必須進(jìn)行氣密性試驗(yàn)。氣密性試驗(yàn)與氣壓試驗(yàn)是不一樣的。該工件的工藝性比較差。這樣不僅有弧形夾，還有一面兩銷(xiāo)對(duì)工件進(jìn)行定位。需要在閥座與擋片之間插入一個(gè)密封裝置，這樣一來(lái)可以減少試驗(yàn)中的誤差。： 底座根據(jù)氣缸尺寸與定位元件的尺寸。在氣缸的設(shè)計(jì)中我們必須要了解關(guān)于氣壓傳動(dòng)的知識(shí)。在氣壓傳動(dòng)中還有用來(lái)感受和傳遞各種信息的氣動(dòng)傳感器。氣壓傳動(dòng)系統(tǒng)中的工作介質(zhì)壓縮空氣的粘性小、可壓縮性大，有利于構(gòu)成柔軟型驅(qū)動(dòng)機(jī)構(gòu)和實(shí)現(xiàn)高速運(yùn)動(dòng)。η11）選擇換向閥1 對(duì)夾具中的氣缸的換向閥選擇本設(shè)計(jì)中選用二位五通換向閥，因氣缸在中間位置需停止，所以二位五通能滿(mǎn)足要求。考慮到上漿機(jī)構(gòu)氣缸和吹掃機(jī)構(gòu)氣缸不同時(shí)工作的特點(diǎn)，由，可導(dǎo)出，取標(biāo)準(zhǔn)管徑為3mm。作為氣壓傳動(dòng)技術(shù)應(yīng)用的雛形大約開(kāi)始與1776年英國(guó)人John Wilkinson 發(fā)明了能產(chǎn)生一個(gè)大氣壓左右的空氣壓縮機(jī)。在沒(méi)有做畢業(yè)設(shè)計(jì)以前覺(jué)得畢業(yè)設(shè)計(jì)只是對(duì)這幾年來(lái)所學(xué)知識(shí)的單純總結(jié)，但是通過(guò)這次做畢業(yè)設(shè)計(jì)發(fā)現(xiàn)自己的看法有點(diǎn)太片面，這次做畢業(yè)設(shè)計(jì)發(fā)現(xiàn)畢業(yè)設(shè)計(jì)不僅是對(duì)前面所學(xué)知識(shí)的一種檢驗(yàn)，而且也是對(duì)自己能力的一種高提。這樣對(duì)我的工作也有很大的幫助，我即將所要參加的工作與我們所學(xué)習(xí)的專(zhuān)業(yè)有著非常密切的聯(lián)系，只要看懂一張圖紙就可以解決許多問(wèn)題，也可以節(jié)省許多的時(shí)間，如果，你看不懂，就不知道怎么去解決它，還需要請(qǐng)教別人，這樣就會(huì)降低工作效率。 of dynamics for inertia, acceleration, and energy。許多原則和設(shè)計(jì)方法不但適用于機(jī)器的設(shè)計(jì)，也適用于非機(jī)器的設(shè)計(jì)。只有這樣，才不致于阻斷創(chuàng)新的思路。設(shè)計(jì)的過(guò)程是重復(fù)和合作的過(guò)程，無(wú)論是正式或非正式的進(jìn)行，對(duì)設(shè)計(jì)者來(lái)說(shuō)每個(gè)階段都很重要。在近年來(lái)的許多產(chǎn)品責(zé)任訴訟案件中，由于錯(cuò)誤地使用產(chǎn)品而受到傷害的原告控告生產(chǎn)廠家，并且贏得判決）；(c)所使用的材料的數(shù)據(jù)不全或是有些數(shù)據(jù)不確定，尤其是當(dāng)其性能數(shù)據(jù)長(zhǎng)期不更新；(d)質(zhì)量控制方法不適當(dāng)和未經(jīng)驗(yàn)證；(e)由一些完全不稱(chēng)職的人員選擇材料。為了激發(fā)創(chuàng)造性思維，下列是設(shè)計(jì)和分析的建議規(guī)則。7. 選擇組合材料。5. 介紹疲勞失效理論并強(qiáng)調(diào)在壓力條件下接近高循環(huán)的疲勞設(shè)計(jì)，這通常用在旋轉(zhuǎn)機(jī)械的設(shè)計(jì)中。機(jī)械設(shè)計(jì)是一項(xiàng)創(chuàng)造性的工作。計(jì)算（圖紙尺寸）檢查是非常重要的。另一個(gè)重要問(wèn)題，設(shè)計(jì)工程師必須能夠同其他有關(guān)人員進(jìn)行交流和磋商。僅僅使用數(shù)據(jù)和公式是不足以在一個(gè)好的設(shè)計(jì)中做出所需的全部決定的。新設(shè)計(jì)本身會(huì)有許多缺陷和未能預(yù)料的問(wèn)題發(fā)生，只有當(dāng)這些缺陷和問(wèn)題被解決之后，才能體現(xiàn)出新產(chǎn)品的優(yōu)越性。由于許多人墨守成規(guī)，這樣做并不是一件容易的事。應(yīng)當(dāng)把機(jī)械設(shè)計(jì)看成是機(jī)械設(shè)計(jì)人員運(yùn)用創(chuàng)造性的才能進(jìn)行產(chǎn)品設(shè)計(jì)、系統(tǒng)分析和制定產(chǎn)品的制造工藝學(xué)的一個(gè)良機(jī)。設(shè)計(jì)人員的基本職責(zé)是努力使機(jī)器來(lái)適應(yīng)人們。仔細(xì)精確的計(jì)算是必要的，以確保設(shè)計(jì)的有效性。11. 介紹盤(pán)式和鼓式離合器以及制動(dòng)器的設(shè)計(jì)和技術(shù)說(shuō)明。3. 回顧應(yīng)力的基本規(guī)律和失效分析。5. 提供良好的應(yīng)力分布和最小的剛度條件。一些設(shè)計(jì)規(guī)則在本節(jié)中，建議要運(yùn)用創(chuàng)造性的態(tài)度來(lái)替代和改進(jìn)。產(chǎn)品的責(zé)任訴訟迫使設(shè)計(jì)人員和公司在選擇材料時(shí)，采用最好的程序。也要選擇原材料和處理原材料的方法。在設(shè)計(jì)的初始階段，應(yīng)該允許設(shè)計(jì)人員充分發(fā)揮創(chuàng)造性，不要受到任何約束。s basic responsibility is diligently causes the machine to adapt the people. This certainly is not an easy work, because certainly does not have to all people to say in fact all is the most superior operating area and the operating process. Another important question, project engineer must be able to carry on the exchange and the consultation with other concerned personnel. In the initial stage, designs the personnel to have to carry on the exchange and the consultation on the preliminary design with the administrative personnel, and is approved. This generally is through the oral discussion, the schematic diagram and the writing material carries on. If front sues, the machine design goal is the production can meet the human need the product. The invention, the discovery and technical knowledge itself certainly not necessarily can bring the advantage to the humanity, only has when they are applied can produce on the product the benefit. Thus, should realize to carries on before the design in a specific product, must first determine whether the people do need this kind of productMust regard as the machine design is the machine design personnel carries on using creative ability the product design, the system analysis and a formulation product manufacture technology good opportunity. Grasps the project elementary knowledge to have to memorize some data and the formula is more important than. The merely service data and the formula is insufficient to the pletely decision which makes in a good design needs. On the other hand, should be earnest precisely carries on all operations. For example, even if places wrong a decimal point position, also can cause the correct design to turn wrongly.A good design personnel should dare to propose the new idea, moreover is willing to undertake the certain risk, when the new method is not suitable, use original method. Therefore, designs the personnel to have to have to have the patience, because spends the time and the endeavor certainly cannot guarantee brings successfully. A brandnew design, the request screen abandons obsoletely many, knows very well the method for the people. Because many person of conservativeness, does this certainly is not an easy matter. A mechanical designer should unceasingly explore the improvement existing product the method, should earnestly choose originally, the process confirmation principle of design in this process, with has not unified it after the confirmation new idea.譯文:機(jī)械設(shè)計(jì)摘要： 機(jī)器是由機(jī)械裝置和其它組件組成的。 Z. Wang amp。這次的設(shè)計(jì)是對(duì)我四年來(lái)所學(xué)的知識(shí)的綜合應(yīng)用，很多知識(shí)都已學(xué)過(guò)，通過(guò)這次畢業(yè)設(shè)計(jì)，將理論與實(shí)際緊密結(jié)合，使我以前不明白，不清楚的地方得到了充分的補(bǔ)充。結(jié)束語(yǔ)隨著答辯時(shí)間的來(lái)臨，畢業(yè)設(shè)計(jì)也接近了尾聲。（4）氣動(dòng)裝置中的氣信號(hào)傳遞速度在聲速以?xún)?nèi)比電子及光速慢，因此，氣動(dòng)控制系統(tǒng)不宜用于元件級(jí)數(shù)過(guò)多的復(fù)雜回路；（5）目前氣壓傳動(dòng)的效率較低。油霧器的作用是當(dāng)壓縮空氣流過(guò)時(shí)，將潤(rùn)滑油噴射成霧狀，隨壓縮空氣流進(jìn)需要的潤(rùn)滑的部件，達(dá)到潤(rùn)滑的目的。： 氣壓輸出力 氣壓輸出力缸徑為63mm，為了安全取缸徑為63mm查機(jī)械設(shè)計(jì)手冊(cè)（單行本）《氣壓傳動(dòng)與控制》得：電空閥氣密性試驗(yàn)用夾具中選SC63*100型號(hào)氣缸，因此缸徑為63mm，行程為100mm. 氣缸 氣缸的相關(guān)尺寸內(nèi)徑ABCDEFGHIJKL32140479328321522176M6140142499332341524177M6150150579338421532238M161. 5M6163153579638421532238801837510847542133402610內(nèi)徑MNOPQRSTVW32141/8``764533121040141/4``675037161450141/4``776247201763143/8``777456201780173/8``995702520結(jié)合圖表最終選擇了SC63*100的氣缸，： 氣缸實(shí)體圖 空壓機(jī)的選擇 氣源裝置是向氣動(dòng)系統(tǒng)提供所需壓縮空氣的動(dòng)力源，空壓機(jī)是氣壓發(fā)生裝置，是將機(jī)械能轉(zhuǎn)換為氣體壓力能的轉(zhuǎn)換裝置。對(duì)氣缸結(jié)構(gòu)的要求一是重量盡量輕，以達(dá)到動(dòng)作靈活、運(yùn)動(dòng)速度高、節(jié)約材料和動(dòng)力，同時(shí)減少運(yùn)動(dòng)的沖擊，二是要有足夠的剛度以保證運(yùn)動(dòng)精度和定位精度。 氣壓傳動(dòng)系統(tǒng)的工作原理氣壓傳動(dòng)系統(tǒng)控制可以在高溫、腐蝕、震動(dòng)、強(qiáng)磁、輻射、多灰塵、易燃、易爆等極其惡劣的環(huán)境下安全、可靠地工作，與其繼電器強(qiáng)電電路、計(jì)算機(jī)和PLC弱電電路相結(jié)合，實(shí)現(xiàn)了
