①單作用氣缸:僅一端有活塞桿,從活塞一側(cè)供氣聚能產(chǎn)生氣壓,氣壓推動(dòng)活塞產(chǎn)生推力伸出,靠彈簧或自重返回
②雙作用氣缸:從活塞兩側(cè)交替供氣,在一個(gè)或兩個(gè)方向輸出力。
③膜片式氣缸:用膜片代替活塞,只在一個(gè)方向輸出力,用彈簧復(fù)位。它的密封性能好,但行程短。
④沖擊氣缸:這是一種新型元件。它把壓縮氣體的壓力能轉(zhuǎn)換為活塞高速(10~20米/秒)運(yùn)動(dòng)的動(dòng)能,借以作功。沖擊氣缸增加了帶有噴口和泄流口的中蓋。中蓋和活塞把氣缸分成儲(chǔ)氣腔、頭腔和尾腔三室。它廣泛用于下料、沖孔、破碎和成型等多種作業(yè)。作往復(fù)擺動(dòng)的氣缸稱擺動(dòng)氣缸,由葉片將內(nèi)腔分隔為二,向兩腔交替供氣,輸出軸作擺動(dòng)運(yùn)動(dòng),擺動(dòng)角小于 280°。此外,還有回轉(zhuǎn)氣缸、氣液阻尼缸和步進(jìn)氣缸等。

SMC氣缸結(jié)構(gòu)
氣缸是由缸筒、端蓋、活塞、活塞桿和密封件組成,其內(nèi)部結(jié)構(gòu)如圖所示: SMC氣缸原理圖
1)缸筒 缸筒的內(nèi)徑大小代表了氣缸輸出力的大小。活塞要在缸筒內(nèi)做平穩(wěn)的往復(fù)滑動(dòng),缸筒內(nèi)表面的表面粗糙度應(yīng)達(dá)到Ra0.8um。對(duì)鋼管缸筒,內(nèi)表面還應(yīng)鍍硬鉻,以減小摩擦阻力和磨損,并能防止銹蝕。缸筒材質(zhì)除使用高碳鋼管外,還是用高強(qiáng)度鋁合金和黃銅。小型氣缸有使用不銹鋼管的。帶磁性開(kāi)關(guān)的氣缸或在耐腐蝕環(huán)境中使用的氣缸,缸筒應(yīng)使用不銹鋼、鋁合金或黃銅等材質(zhì)。 SMC CM2氣缸活塞上采用組合密封圈實(shí)現(xiàn)雙向密封,活塞與活塞桿用壓鉚鏈接,不用螺母。 2)端蓋 端蓋上設(shè)有進(jìn)排氣通口,有的還在端蓋內(nèi)設(shè)有緩沖機(jī)構(gòu)。桿側(cè)端蓋上設(shè)有密封圈和防塵圈,以防止從活塞桿處向外漏氣和防止外部灰塵混入缸內(nèi)。桿側(cè)端蓋上設(shè)有導(dǎo)向套,以提高氣缸的導(dǎo)向精度,承受活塞桿上少量的橫向負(fù)載,減小活塞桿伸出時(shí)的下彎量,延長(zhǎng)氣缸使用壽命。導(dǎo)向套通常使用燒結(jié)含油合金、前傾銅鑄件。端蓋過(guò)去常用可鍛鑄鐵,現(xiàn)在為減輕重量并防銹,常使用鋁合金壓鑄,微型缸有使用黃銅材料的。

根據(jù)工作所需力的大小來(lái)確定活塞桿上的推力和拉力。由此來(lái)選擇氣缸時(shí)應(yīng)使氣缸的輸出力稍有余量。若缸徑選小了,輸出力不夠,氣缸不能正常工作;但缸徑過(guò)大,不僅使設(shè)備笨重、成本高,同時(shí)耗氣量增大,造成能源浪費(fèi)。在夾具設(shè)計(jì)時(shí),應(yīng)盡量采用增力機(jī)構(gòu),以減少氣缸的尺寸。

SMC 氣缸所設(shè)緩沖裝置種類很多,上述只是其中之一,當(dāng)然也可以在氣動(dòng)回路上采取措施,達(dá)到緩沖目的。 組合組合氣缸一般指氣缸與液壓缸相組合形成的氣-液阻尼缸、氣-液增壓缸等。*,通常氣缸采用的工作介質(zhì)是壓縮空氣,其特點(diǎn)是動(dòng)作快,但速度不易控制,當(dāng)載荷變化較大時(shí),容易產(chǎn)生“爬行”或“自走”現(xiàn)象;而液壓缸采用的工作介質(zhì)是通常認(rèn)為不可壓縮的液壓油,其特點(diǎn)是動(dòng)作不如氣缸快,但速度易于控制,當(dāng)載荷變化較大時(shí),采用措施得當(dāng),一般不會(huì)產(chǎn)生“爬行”和“自走”現(xiàn)象。把氣缸與液壓缸巧妙組合起來(lái),取長(zhǎng)補(bǔ)短,即成為氣動(dòng)系統(tǒng)中普遍采用的氣-液阻尼缸。氣-液阻尼缸工作原理見(jiàn)圖42.2-5。實(shí)際是氣缸與液壓缸串聯(lián)而成,兩活塞固定在同一活塞桿上。液壓缸不用泵供油,只要充滿油即可,其進(jìn)出口間裝有液壓?jiǎn)蜗蜷y、節(jié)流閥及補(bǔ)油杯。當(dāng)氣缸右端供氣時(shí),氣缸克服載荷帶動(dòng)液壓缸活塞向左運(yùn)動(dòng)(氣缸左端排氣),此時(shí)液壓缸左端排油,單向閥關(guān)閉,油只能通過(guò)節(jié)流閥流入液壓缸右腔及油杯內(nèi),這時(shí)若將節(jié)流閥閥口開(kāi)大,則液壓缸左腔排油通暢,兩活塞運(yùn)動(dòng)速度就快,反之,若將節(jié)流閥閥口關(guān)小,液壓缸左腔排油受阻,兩活塞運(yùn)動(dòng)速度會(huì)減慢。這樣,調(diào)節(jié)節(jié)流閥開(kāi)口大小,就能控制活塞的運(yùn)動(dòng)速度??梢钥闯觯瑲庖鹤枘岣椎妮敵隽?yīng)是氣缸中壓縮空氣產(chǎn)生的力(推力或拉力)與液壓缸中油的阻尼力之差。
