SMC氣(qi)缸(gang)是氣(qi)動元部件之(zhi)一，它的構造(zao)是？

　　SMC氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)是(shi)關鍵(jian)的(de)(de)氣(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)式驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)器(qi)(qi)(qi)(qi)元器(qi)(qi)(qi)(qi)件之(zhi)一(yi)(yi)(yi)，它有各種類型。依據(ju)(ju)功(gong)(gong)效方法可分成(cheng)：單功(gong)(gong)效氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)和(he)雙功(gong)(gong)效氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)。單功(gong)(gong)效氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)就是(shi)指氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)的(de)(de)活塞桿的(de)(de)某(mou)一(yi)(yi)(yi)個方位(wei)(wei)的(de)(de)健(jian)(jian)身運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)由空(kong)氣(qi)(qi)(qi)(qi)壓縮驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)器(qi)(qi)(qi)(qi)，而(er)另一(yi)(yi)(yi)個反(fan)過來方位(wei)(wei)的(de)(de)健(jian)(jian)身運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)由彈黃驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)器(qi)(qi)(qi)(qi)校準。雙功(gong)(gong)效氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)就是(shi)指氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)活塞桿的(de)(de)2個方位(wei)(wei)的(de)(de)健(jian)(jian)身運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)都由空(kong)氣(qi)(qi)(qi)(qi)壓縮驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)器(qi)(qi)(qi)(qi)。氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)依據(ju)(ju)其運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)方式能夠分成(cheng)三類：勻(yun)速直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)、轉動(dong)(dong)(dong)(dong)(dong)(dong)氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)隨和(he)爪(zhua)。勻(yun)速直線(xian)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)器(qi)(qi)(qi)(qi)執(zhi)行(xing)(xing)器(qi)(qi)(qi)(qi)做(zuo)平(ping)行(xing)(xing)線(xian)反(fan)復(fu)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)；轉動(dong)(dong)(dong)(dong)(dong)(dong)氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)器(qi)(qi)(qi)(qi)執(zhi)行(xing)(xing)器(qi)(qi)(qi)(qi)做(zuo)轉動(dong)(dong)(dong)(dong)(dong)(dong)反(fan)復(fu)運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)；氣(qi)(qi)(qi)(qi)爪(zhua)驅(qu)(qu)動(dong)(dong)(dong)(dong)(dong)(dong)器(qi)(qi)(qi)(qi)執(zhi)行(xing)(xing)器(qi)(qi)(qi)(qi)做(zuo)開(kai)閉健(jian)(jian)身運(yun)動(dong)(dong)(dong)(dong)(dong)(dong)，關鍵(jian)用以產品工件或(huo)是(shi)商品的(de)(de)爬取(qu)、夾緊等層面(mian)。依據(ju)(ju)氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)的(de)(de)應用工作狀(zhuang)況自然(ran)環(huan)(huan)(huan)境(jing)區別，可分成(cheng)：一(yi)(yi)(yi)般(ban)(ban)氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)、防潮氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)、清(qing)潔氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)。一(yi)(yi)(yi)般(ban)(ban)氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)適用一(yi)(yi)(yi)般(ban)(ban)的(de)(de)辦(ban)公環(huan)(huan)(huan)境(jing)；防潮氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)適用具備一(yi)(yi)(yi)定水(shui)平(ping)的(de)(de)霧水(shui)和(he)環(huan)(huan)(huan)境(jing)濕度自然(ran)環(huan)(huan)(huan)境(jing)下；清(qing)潔氣(qi)(qi)(qi)(qi)缸(gang)(gang)(gang)(gang)關鍵(jian)運(yun)用于清(qing)潔房間內（Clean Room）的(de)(de)辦(ban)公環(huan)(huan)(huan)境(jing)中。

　　SMC氣缸構(gou)造(zao)：

　　1.氣(qi)缸是由缸套、端(duan)蓋(gai)、活塞、活塞桿和液(ye)壓密(mi)封件等構成：

　　2：端蓋

　　SMC氣(qi)缸端(duan)(duan)(duan)蓋(gai)(gai)上(shang)設(she)(she)有(you)進(jin)排(pai)氣(qi)管通口，有(you)的(de)(de)(de)(de)仍在(zai)端(duan)(duan)(duan)蓋(gai)(gai)內設(she)(she)有(you)緩存組織。桿(gan)(gan)側(ce)端(duan)(duan)(duan)蓋(gai)(gai)上(shang)設(she)(she)有(you)密封圈和防塵圈，以避免(mian)從活塞桿(gan)(gan)處向(xiang)外漏(lou)汽和避免(mian)外界塵土滲入主(zhu)缸。 桿(gan)(gan)側(ce)端(duan)(duan)(duan)蓋(gai)(gai)上(shang)設(she)(she)有(you)導向(xiang)性套， 以提升(sheng) 氣(qi)缸的(de)(de)(de)(de)導向(xiang)性精密度， 承(cheng)擔活塞桿(gan)(gan)上(shang)小量的(de)(de)(de)(de)橫著負荷， 減少活塞桿(gan)(gan)外伸(shen)時的(de)(de)(de)(de)下彎量， 增加氣(qi)缸使用期限。導向(xiang)性套一般(ban) 應用煅燒含油(you)量鋁合金、前伸(shen)銅鑄件。端(duan)(duan)(duan)蓋(gai)(gai)以往(wang)常見可鍛鑄鐵，為緩解(jie)凈重并防

　　銹，常(chang)應用(yong)鋁合金鑄造，小(xiao)型缸有應用(yong)紫銅原(yuan)材料的。

　　3：活塞

　　SMC氣(qi)(qi)缸活(huo)(huo)塞(sai)(sai)(sai)(sai)是氣(qi)(qi)缸中的受工作壓力零件。 為(wei)避(bi)免活(huo)(huo)塞(sai)(sai)(sai)(sai)左(zuo)右兩個腔互相竄氣(qi)(qi)， 設有(you)活(huo)(huo)塞(sai)(sai)(sai)(sai)密(mi)封圈。 活(huo)(huo)塞(sai)(sai)(sai)(sai)上的耐磨損環(huan)可提(ti)升 氣(qi)(qi)缸的主(zhu)導性，降(jiang)低活(huo)(huo)塞(sai)(sai)(sai)(sai)密(mi)封圈的摩擦系數，降(jiang)低摩阻。耐磨損環(huan)長應用聚氨酯材料(liao)、聚四氟乙(yi)烯(xi)、 編織膠(jiao)管防腐蝕(shi)涂料(liao)等(deng)原材料(liao)。 活(huo)(huo)塞(sai)(sai)(sai)(sai)的總(zong)寬(kuan)由密(mi)封圈規格和必(bi)需的滾動一部分長短來決(jue)策。

　　滾動一(yi)部分過短(duan)， 易造成(cheng)初期(qi)損(sun)壞和卡住(zhu)。 活塞的(de)材料常(chang)見鋁(lv)合金型材和生鐵， 中小型缸的(de)活塞有紫(zi)銅做(zuo)成(cheng)的(de)。

　　4：活塞桿

　　SMC氣缸活塞桿是(shi)氣缸中(zhong)最(zui)重要(yao)的承(cheng)受力零件。一般 應用(yong)中(zhong)碳(tan)鋼(gang)、表層經鍍(du)硬鉻解決、或應用(yong)不銹鋼(gang)板(ban)、以耐腐(fu)蝕，并提(ti)升 密封(feng)圈的耐磨性能。

　　5：密封圈

　　SMC氣缸或(huo)反(fan)復運動處(chu)的構件(jian)密(mi)封(feng)性(xing)稱之為(wei)動密(mi)封(feng)性(xing)，靜止不(bu)動件(jian)一部分(fen)的密(mi)封(feng)性(xing)稱之為(wei)填料密(mi)封(feng)。缸套(tao)與端蓋的聯接方(fang)式 關鍵有下列幾類(lei)：總體型、鉚合型、外螺紋(wen)連接 型、法蘭盤型、支撐桿(gan)型。

　　6：SMC氣缸工作中時(shi)要靠空氣壓縮中的焊接煙塵對活塞開展潤化(hua)。也(ye)是(shi)有小(xiao)一部分(fen)免潤化(hua)氣缸。
