    SMC氣缸種類:氣壓傳動(dòng)中將壓縮氣體的壓力能轉(zhuǎn)換為機(jī)械能的氣動(dòng)執(zhí)行元件。氣缸有作往復(fù)直線運(yùn)動(dòng)的和作往復(fù)擺動(dòng)的兩類(見(jiàn)圖)。作往復(fù)直線運(yùn)動(dòng)的氣缸又可分為單作用、雙作用、膜片式和沖擊氣缸 4種。  ?、賳巫饔脷飧祝簝H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。  ?、陔p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。  ?、軟_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?;钊诟淄矁?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。
