【正文】 。改造后的車(chē)床，應(yīng)具有高的靜、動(dòng)態(tài)剛度；運(yùn)動(dòng)副之間的摩擦因數(shù)??；傳動(dòng)無(wú)間隙；功率大；便于操作和維修。（2） 將主軸進(jìn)行改造，使之能與標(biāo)準(zhǔn)部件 KEF250 型動(dòng)力卡盤(pán)相配套；同時(shí)具有符合數(shù)控車(chē)床的加工精度。對(duì)機(jī)械部分的改造主要包括下列部分：（1） 對(duì)車(chē)床的傳動(dòng)系統(tǒng)進(jìn)行改造：去掉冗余的齒輪。 數(shù)控在改造中的機(jī)械部件改造機(jī)床數(shù)控改造時(shí)應(yīng)盡量達(dá)到上述要求，應(yīng)對(duì)主要部件進(jìn)行相應(yīng)的改造，使其達(dá)到要求，這樣才能達(dá)到預(yù)期的改造目的。經(jīng)濟(jì)性數(shù)控車(chē)床，主要依靠?jī)煞矫鎭?lái)保證和提高被加工零件的精度：一是系統(tǒng)的控制精度；二是機(jī)床本身的機(jī)械傳動(dòng)精度。數(shù)控機(jī)床改造一般是對(duì)普通機(jī)床某些部位做一定的改造，配上數(shù)控裝置，從而使機(jī)床具有數(shù)控加工能力。（5）擁有自動(dòng)報(bào)警，自動(dòng)監(jiān)控，自動(dòng)補(bǔ)償?shù)榷喾N自律功能，因而可實(shí)現(xiàn)長(zhǎng)時(shí)間無(wú)人看管加工。（3）加工零件的精度高，尺寸分散度小，使裝配容易，不再需要“修配” 。由于計(jì)算機(jī)有高超的運(yùn)算能力，可以瞬時(shí)準(zhǔn)確的計(jì)算出每個(gè)坐標(biāo)軸瞬時(shí)應(yīng)該運(yùn)動(dòng)的運(yùn)動(dòng)量，因此可以復(fù)合成復(fù)雜的曲線或曲面。 普通機(jī)床數(shù)控化改造的必要性 數(shù)控機(jī)床比較傳統(tǒng)機(jī)床有以下突出的優(yōu)越性。要較好的解決上述我問(wèn)題，要走普通機(jī)床數(shù)控改造之路。但是數(shù)控機(jī)床的應(yīng)用也受到其他條件的限制。數(shù)控機(jī)床就是這樣的背景下產(chǎn)生的。通過(guò)單片機(jī)的設(shè)計(jì)，構(gòu)成控制系統(tǒng)。對(duì)進(jìn)給系統(tǒng)，我把原先的滑動(dòng)絲杠換成滾珠絲杠，以提高精度和效率，并由原先的手動(dòng)控制，改造成由電動(dòng)機(jī)控制。 本設(shè)計(jì)是對(duì) C618 普通臥式車(chē)床進(jìn)行數(shù)控化改造。即在不改變?cè)瓉?lái)功能的前提條件下，還要特別講究經(jīng)濟(jì)性、可靠性、性能優(yōu)越等。 數(shù)控機(jī)床的工作過(guò)程是將加工零件的幾何信息和工藝信息進(jìn)行數(shù)字化處理，即對(duì)所有的操作步驟和刀具與工件之間的相對(duì)位移，以及進(jìn)給速度等都用數(shù)字化的代碼表示。機(jī)械加工工藝過(guò)程的自動(dòng)化成為實(shí)現(xiàn)上述要求的最重要的措施之一。xxxxxxx畢 業(yè) 設(shè) 計(jì)（論 文）設(shè)計(jì)（論文）題目：C618 型臥式車(chē)床橫向進(jìn)給數(shù)控化改造 2022年 4 月 7 日摘要20 世紀(jì)中葉數(shù)控技術(shù)和數(shù)控機(jī)床的誕生標(biāo)志著生產(chǎn)和控制領(lǐng)域的一個(gè)嶄新時(shí)代的到來(lái)。 科學(xué)技術(shù)和社會(huì)生產(chǎn)力的迅速發(fā)展，對(duì)機(jī)械產(chǎn)品的質(zhì)量和生產(chǎn)率提出了越來(lái)越高的要求。它不僅能夠提高產(chǎn)品的質(zhì)量、提高生產(chǎn)率、降低生產(chǎn)成本，還能夠極大地改善生產(chǎn)者的勞動(dòng)條件。而經(jīng)濟(jì)型的數(shù)控改造則對(duì)數(shù)控機(jī)床有了更新的要求。所以，在改造的同時(shí)，盡量不要改變?cè)瓉?lái)的結(jié)構(gòu)。為了實(shí)現(xiàn)把 C618 普通臥式車(chē)床改造成經(jīng)濟(jì)型數(shù)控車(chē)床，我針對(duì)此車(chē)床的主傳動(dòng)系統(tǒng)，X 向進(jìn)給系統(tǒng)進(jìn)行數(shù)控改造，并增加了 CNC 裝置和伺服系統(tǒng)。通過(guò)變頻器實(shí)現(xiàn)主軸傳動(dòng)和進(jìn)給機(jī)構(gòu)的無(wú)級(jí)變速。關(guān)鍵詞：數(shù)控改造，滾珠絲杠.ABSTRACTNaissance that 20 century middle period few technique is with the few machine the bed scribe to produce with control ing of a brandnew ages of realm. The science technique bring upped with rate of production to the quantity of the machine product with the quick development of the social productivity more and more high automation that machine process the craft process one of the most important measure of being to realizes the above can not only increase the product quantity,increase the rate of production ,lower the production cost ,and can be still biggest ameliorative production of labor term. Work process that few machine the bed will process the spare parts several why the information proceedswith the craft informations the arithmetic figure handle,then operation allly the step have with knife with of the work piece the code for of opposite moving,and entering giving the speed waiting all using the arithmetic figure few of the economic types then reform the logarithms achine bed contain new request.Namelystillwant the superior particular about and economic,dependable,function under not changes originally the function’s prior ,at reform at the same time ,and as far as possible don’t change original construction. This design is C618 ordinary vertical horizontal machine NC transformation. In order to achieve the C618 vertical horizontal machine into the general economy CNC milling machine, I am against this horizontal the main drive system, X to the feed system NC transformation, and to increase the CNC servo devices and systems. The feed system, I replaced the original sliding screw ball screws, to improve accuracy and efficiency, and the original manual control, into the motor control. Converter to achieve through the main transmission and feed the CVT. SCM through the design of a control system. Key words: NC transformation, ball screw.目錄摘要 ..................................................................................................................1ABSTRACT .....................................................................................................2第一章 普通機(jī)床數(shù)控化改造的概況 ............................................................1 數(shù)控機(jī)床的產(chǎn)生 ..............................................1 普通機(jī)床數(shù)控化改造的必要性 ..................................1 數(shù)控在改造中的機(jī)械部件改造 ..................................2 數(shù)控在改造中的電氣部分改造 ..................................2第二章 緒論 ..................................................................................................4 ................................4 ....................................................5第三章 進(jìn)給伺服機(jī)械部分設(shè)計(jì)與計(jì)算 ........................................................7 .................
