T6113電氣控制系統(tǒng)的設(shè)計(jì)(論文+DWG圖紙)

T6113電氣控制系統(tǒng)的設(shè)計(jì)(論文+DWG圖紙),t6113,電氣,控制系統(tǒng),設(shè)計(jì),論文,dwg,圖紙 摘要 隨著機(jī)械工業(yè)的發(fā)展，作為工作母機(jī)的各類(lèi)機(jī)床得到了廣泛的應(yīng)用，而這些機(jī)床的自動(dòng)化和精密程度卻有很大差異。在歐美、日本等國(guó)家里，他們的機(jī)床數(shù)控化程度都相對(duì)比較高，但在我國(guó)國(guó)內(nèi)的機(jī)床大約有90%多還處于老式的繼電器控制下。由于繼電器控制的機(jī)床有耗材、耗能、故障率高的缺陷，從而浪費(fèi)了很多的人力、物力和財(cái)力。如果說(shuō)把這些機(jī)床全部都更新?lián)Q代，那樣會(huì)需要很大一筆資金，就目前情況上來(lái)說(shuō)是不現(xiàn)實(shí)的，所以就有人開(kāi)始嘗試從控制部分的改造方面來(lái)下手，將它們的性能提升一個(gè)檔次，更可以解決它的一些弊端。 基于以上情況，我選擇了用PLC來(lái)完成T6113臥式鏜床的電氣控制部分這個(gè)題目，目的是使機(jī)床能快速響應(yīng)動(dòng)作，靈活可靠的完成生產(chǎn)任務(wù)，而故障率要相應(yīng)降低。PLC以?xún)?nèi)部的邏輯觸點(diǎn)代替了繼電器的機(jī)械觸點(diǎn)，來(lái)控制機(jī)床的動(dòng)作，邏輯觸點(diǎn)與機(jī)械觸點(diǎn)相比動(dòng)作時(shí)間大大縮短，連接快而可靠，還有就是它的壽命比機(jī)械觸點(diǎn)有很大幅度的增長(zhǎng)，可達(dá)到幾百萬(wàn)次到千萬(wàn)次。 經(jīng)過(guò)設(shè)計(jì)并作了實(shí)物的演示，結(jié)果證明了設(shè)計(jì)的成功。 關(guān)鍵詞：繼電器 故障率 邏輯觸點(diǎn) Abstract Was each kind of tool machine of the machine tool to get an extensive application along with the development of the machine industry, but the automation and precise degree of these tool machines contain very big difference. In the Europe and America, Japanese etc. nation, their tool machine number controls to turn degree all opposite higher, but at our country the local tool machine has 90% about to still be placed in old style much of after electric appliances control under. In order to hasing already consumed a material, consume an ability and breaking down high blemish of rate after the tool machine of the electric appliances control, waste a lot of man powers, material resource and financial power thus. If say that all renewing these tool machines changes generation, will need so very greatly one fee for writing gold, the circumstance comes up to say to be not realistic currently, so start try for someone to start from the reformation aspect of the control part, promote their function a file time, can even solve some of its irregularities. According to the above circumstance, I chose to use parts of this topics of the electricity control that the PLC completes the T6113 lie type beds, the purpose makes the tool machine be able to respond to action quickly, the vivid and dependable completion production mission, but break down a rate and correspond to lower. The PLC touched to order to replace by the logic of the inner part after the machine of the electric appliances touch a point, control the action of the tool machine, the logic touches to order to touch with machine to order to compare action time to shorten consumedly, conjunction quick but credibility, also have to be its life span ratio machine to touch to order to have a very significant growth, can attain several million times arrive the ten million time. Through design and made real object to play to show, success proven a design as a result.
