液壓系統(tǒng)結(jié)構(gòu)

液壓系統(tǒng)由信號(hào)控制和液壓動(dòng)力兩部分組成，信號(hào)控制部分用于驅(qū)動(dòng)液壓動(dòng)力部分中的控制閥動(dòng)作。

液壓動(dòng)力部分采用回路圖方式表示，以表明不同功能元件之間的相互關(guān)系。液壓源含有液壓泵、電動(dòng)機(jī)和液壓輔助元件；液壓控制部分含有各種控制閥，其用于控制工作油液的流量、壓力和方向；執(zhí)行部分含有液壓缸或液壓馬達(dá)，其可按實(shí)際要求來選擇。

 

組合機(jī)床動(dòng)力滑臺(tái)液壓系統(tǒng)

動(dòng)力滑臺(tái)是組合機(jī)床的一種通用部件，在滑臺(tái)上可以配置各種工藝用途的切削頭。機(jī)床液壓動(dòng)力滑臺(tái)可以實(shí)現(xiàn)多種不同的工作循環(huán)，其中一種比較典型的工作循環(huán)是：快進(jìn)→ 一工進(jìn)→二工進(jìn)→死擋鐵停留→快退→停止。 使液壓缸差動(dòng)聯(lián)接以實(shí)現(xiàn)快速運(yùn)動(dòng)； 系統(tǒng)中采用限壓式變量葉片泵供油； 用行程閥、液控順序閥實(shí)現(xiàn)快進(jìn)與工進(jìn)的轉(zhuǎn)換； 電液換向閥 使液壓缸差動(dòng)聯(lián)接和變量泵以實(shí)現(xiàn)快速運(yùn)動(dòng)；

（1）快進(jìn) 按下啟動(dòng)按鈕，三位五通電液動(dòng)換向閥5的先導(dǎo)電磁換向閥1YA得電，使之閥芯右移，左位進(jìn)入工作狀態(tài)。 用二位二通電磁換向閥實(shí)現(xiàn)一工進(jìn)和二工進(jìn)之間的速度換接。

（2）一次工作在快進(jìn)行程結(jié)束，滑臺(tái)上的擋鐵壓下行程閥。 用行程閥、液控順序閥實(shí)現(xiàn)快進(jìn)與工進(jìn)的轉(zhuǎn)換； 用二位二通電磁換向閥實(shí)現(xiàn)一工進(jìn)和二工進(jìn)之間的速度換接。

（3）第二次工作進(jìn)給 為保證進(jìn)給的尺寸精度，采用了死擋鐵停留來限位。

（4）死擋鐵停留 當(dāng)動(dòng)力滑臺(tái)第二次工作進(jìn)給終了碰上死擋鐵后，液壓缸停止不動(dòng)，系統(tǒng)的壓力進(jìn)一步升高，達(dá)到壓力繼電器15的調(diào)定值時(shí)，經(jīng)過時(shí)間繼電器的延時(shí)，再發(fā)出電信號(hào)，使滑臺(tái)退回。在時(shí)間繼電器延時(shí)動(dòng)作前，滑臺(tái)停留在死擋塊限定的位置上。

（5）快退 時(shí)間繼電器發(fā)出電信號(hào)后，電液換向閥右位工作。 這時(shí)系統(tǒng)的壓力較低，變量泵2輸出流量大，動(dòng)力滑臺(tái)快速退回。由于活塞桿的面積大約為活塞的一半，所以動(dòng)力滑臺(tái)快進(jìn)、快退的速度大致相等。

（6）原位停止 當(dāng)動(dòng)力滑臺(tái)退回到原始位置時(shí)，擋塊壓下行程開關(guān)，電液換向閥處于中位，動(dòng)力滑臺(tái)停止運(yùn)動(dòng)，變量泵卸荷。

液壓比例控制系統(tǒng)

以比例控制元件完成動(dòng)力與運(yùn)動(dòng)方向控制，分為比例壓力閥、比例流量閥、比例方向閥及比例方向流量閥，可為模擬量輸入或數(shù)字量輸入，視是否帶反饋分為開環(huán)控制與閉環(huán)控制，一般獲得頻率不是很高(10HZ)以內(nèi)，高頻響閥可實(shí)現(xiàn)較高頻率。

若精度要求不高可考慮使用電液比例控制系統(tǒng)，一般電液比例控制系統(tǒng)可達(dá)至以下精度

位置精度- 3 mm

速度精度帶壓力補(bǔ)償器- 3%

加減速斜坡時(shí)間-0.5秒

壓力帶位移傳感器的產(chǎn)品-比例壓力閥設(shè)定的0.3% (如壓力設(shè)定為200bar,精度可達(dá)0.6bar)

一般的多驅(qū)動(dòng)器液壓系統(tǒng)皆要求流量及壓力控制，提供比例壓力及流量控制系統(tǒng)

開環(huán)式比例壓力及流量控制可用于定量泵及變量泵系統(tǒng)。

速度和流量比例控制的分別是:

流量控制只控制供油量,并不控制驅(qū)動(dòng)元件的運(yùn)動(dòng)方向;

若系統(tǒng)負(fù)載及變速要求高，則要使用速度控制系統(tǒng)。

速度比例控制多用于自動(dòng)化控制、注塑機(jī)、壓力機(jī)等
