從廣義上講,氣(qi)(qi)動(dong)(dong)工(gong)(gong)(gong)(gong)(gong)具(ju)主要是利用壓(ya)縮(suo)空氣(qi)(qi)帶動(dong)(dong)氣(qi)(qi)動(dong)(dong)馬達(da)而(er)對外輸(shu)出(chu)動(dong)(dong)能工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)的(de)一(yi)種工(gong)(gong)(gong)(gong)(gong)具(ju),根據其基本工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)(zuo)方(fang)式(shi)(shi)可(ke)分(fen)為:1)旋轉式(shi)(shi)(偏心可(ke)動(dong)(dong)葉(xie)片式(shi)(shi)). 2)往復式(shi)(shi)(容積活(huo)塞式(shi)(shi))一(yi)般(ban)氣(qi)(qi)動(dong)(dong)工(gong)(gong)(gong)(gong)(gong)具(ju)主要由動(dong)(dong)力輸(shu)出(chu)部(bu)(bu)分(fen)、作(zuo)(zuo)(zuo)業形(xing)式(shi)(shi)轉化部(bu)(bu)分(fen)、進(jin)排氣(qi)(qi)路(lu)部(bu)(bu)分(fen)、運作(zuo)(zuo)(zuo)開啟與停止控制部(bu)(bu)分(fen)、工(gong)(gong)(gong)(gong)(gong)具(ju)殼體(ti)等(deng)主體(ti)部(bu)(bu)分(fen),當然氣(qi)(qi)動(dong)(dong)工(gong)(gong)(gong)(gong)(gong)具(ju)運作(zuo)(zuo)(zuo)還必須(xu)有能源(yuan)供(gong)給部(bu)(bu)分(fen)、空氣(qi)(qi)過(guo)濾與氣(qi)(qi)壓(ya)調節部(bu)(bu)分(fen)以(yi)及(ji)工(gong)(gong)(gong)(gong)(gong)具(ju)附件等(deng)。
1、 動(dong)力輸出(chu)(chu)部分:它(ta)(ta)是(shi)氣動(dong)工具主要組(zu)成(cheng)部件之一(yi),主要有氣動(dong)馬(ma)(ma)(ma)(ma)達(da)(da)及動(dong)力輸出(chu)(chu)齒輪(lun)組(zu)成(cheng),它(ta)(ta)依(yi)靠(kao)高(gao)(gao)壓力的(de)壓縮空氣吹動(dong)馬(ma)(ma)(ma)(ma)達(da)(da)葉片(pian)(pian)而(er)使馬(ma)(ma)(ma)(ma)達(da)(da)轉(zhuan)(zhuan)子(zi)轉(zhuan)(zhuan)動(dong),對外輸出(chu)(chu)旋轉(zhuan)(zhuan)運動(dong),并通過齒輪(lun)帶動(dong)整個作業形(xing)式轉(zhuan)(zhuan)化部分運動(dong)。按(an)定子(zi)與(yu)轉(zhuan)(zhuan)子(zi)是(shi)否同(tong)心,氣動(dong)馬(ma)(ma)(ma)(ma)氣動(dong)馬(ma)(ma)(ma)(ma)達(da)(da)可分為(wei)(wei)同(tong)心馬(ma)(ma)(ma)(ma)達(da)(da)和偏心馬(ma)(ma)(ma)(ma)達(da)(da),按(an)進(jin)氣孔的(de)數量多(duo)少,可分為(wei)(wei)單進(jin)氣孔馬(ma)(ma)(ma)(ma)達(da)(da)、雙進(jin)氣孔馬(ma)(ma)(ma)(ma)達(da)(da)和多(duo)進(jin)氣孔馬(ma)(ma)(ma)(ma)達(da)(da)等。無論是(shi)何種形(xing)式的(de)氣動(dong)馬(ma)(ma)(ma)(ma)達(da)(da),都(dou)是(shi)依(yi)靠(kao)壓縮空氣吹動(dong)馬(ma)(ma)(ma)(ma)達(da)(da)葉片(pian)(pian)帶動(dong)轉(zhuan)(zhuan)子(zi)旋轉(zhuan)(zhuan)的(de),馬(ma)(ma)(ma)(ma)達(da)(da)葉片(pian)(pian)在高(gao)(gao)速旋轉(zhuan)(zhuan)時(shi),時(shi)刻與(yu)定子(zi)內壁(bi)發生摩擦,它(ta)(ta)是(shi)馬(ma)(ma)(ma)(ma)達(da)(da)內最為(wei)(wei)常見的(de)易損(sun)部件,因而(er)它(ta)(ta)對壓縮空氣的(de)質量和壓縮空氣中是(shi)否含潤滑油分子(zi)要求很高(gao)(gao);
2、 作業(ye)形式(shi)轉化部(bu)分(fen):它主要(yao)是(shi)(shi)將馬達輸出的(de)旋轉運動(dong)(dong)進(jin)行相應的(de)轉化。在汽(qi)車(che)制造業(ye)中,由(you)于以螺紋聯接的(de)方式(shi)甚多,大部(bu)分(fen)是(shi)(shi)旋轉運動(dong)(dong),當然也(ye)有(you)直線往復(fu)運動(dong)(dong)。對于不同類型(xing)的(de)氣(qi)動(dong)(dong)工具(ju)(ju),作業(ye)形式(shi)轉化部(bu)分(fen)主要(yao)分(fen)為機械式(shi)離合器及行星齒輪組、摩(mo)擦片(pian)式(shi)離合器及行星齒輪組、液壓油缸、扭力桿及錘打塊組等(deng)。以上(shang)部(bu)件均以旋轉運動(dong)(dong)為基礎(chu)的(de)重要(yao)部(bu)件,它決定著該氣(qi)動(dong)(dong)擰緊(jin)工具(ju)(ju)的(de)扭力大小、轉速快(kuai)慢、擰緊(jin)精(jing)度等(deng)重要(yao)參數,由(you)于它不停的(de)離合、受(shou)壓或扭矩轉變,故它的(de)組成部(bu)件易受(shou)損壞;
3、 進排氣路部分:顯而易(yi)見,進排氣路部分是(shi)壓縮空氣進出的相(xiang)關通道,是(shi)保障馬達(da)正常運動的能源(yuan)供給系統;
4、 運動開(kai)啟與停止控制部分,即通(tong)常所述(shu)的氣動開(kai)關(guan),由于它時(shi)刻(ke)和操作人(ren)員及外界物體直接接觸(chu),且多工程塑料(liao)制品,故易出現損壞;
5、 能(neng)源供給部分:壓(ya)(ya)(ya)縮空(kong)氣主要是空(kong)壓(ya)(ya)(ya)機將大氣進行(xing)壓(ya)(ya)(ya)縮后而形(xing)成的,由(you)壓(ya)(ya)(ya)縮空(kong)氣管道輸送至相(xiang)關的用氣電,且呈脈動狀;
6、 空(kong)(kong)氣(qi)過(guo)濾(lv)及氣(qi)壓(ya)(ya)(ya)調(diao)節(jie)(jie)部(bu)(bu)分(fen):由于壓(ya)(ya)(ya)縮(suo)(suo)空(kong)(kong)氣(qi)通(tong)常是通(tong)過(guo)無縫鋼(gang)管制造的管道進行(xing)輸送的,在長期(qi)使(shi)(shi)用時,其內壁的銹蝕物、壓(ya)(ya)(ya)縮(suo)(suo)空(kong)(kong)氣(qi)中(zhong)的水分(fen)、粉塵等(deng)將(jiang)不(bu)斷形成(cheng)。若(ruo)這樣(yang)的壓(ya)(ya)(ya)縮(suo)(suo)空(kong)(kong)氣(qi)不(bu)進行(xing)任何處(chu)理,直接(jie)進入氣(qi)動(dong)馬(ma)達(da),則將(jiang)導(dao)致(zhi)馬(ma)達(da)壽命(ming)大大縮(suo)(suo)短,從而(er)致(zhi)使(shi)(shi)整把(ba)工(gong)具動(dong)力(li)輸出不(bu)足(zu)、且不(bu)穩(wen)定,易造成(cheng)馬(ma)達(da)等(deng)零部(bu)(bu)件(jian)(jian)連環損(sun)壞的現象,為此(ci)在由管道輸送的壓(ya)(ya)(ya)縮(suo)(suo)空(kong)(kong)氣(qi)至氣(qi)動(dong)工(gong)具之間,必須設置(zhi)壓(ya)(ya)(ya)縮(suo)(suo)空(kong)(kong)氣(qi)過(guo)濾(lv)、調(diao)節(jie)(jie)裝置(zhi),氣(qi)動(dong)三聯件(jian)(jian)承擔了該項任務(wu)。氣(qi)動(dong)三聯件(jian)(jian)主要(yao)由氣(qi)壓(ya)(ya)(ya)表(biao)、過(guo)濾(lv)器(qi)(qi)、油霧器(qi)(qi)、調(diao)壓(ya)(ya)(ya)器(qi)(qi)等(deng)部(bu)(bu)分(fen)組成(cheng),其中(zhong)過(guo)濾(lv)器(qi)(qi)中(zhong)內置(zhi)濾(lv)芯(xin),在使(shi)(shi)用一段時間后(hou)要(yao)進行(xing)維護清洗、定期(qi)更換(huan);
7、 工(gong)具附件(jian):這里的(de)工(gong)具附件(jian)是指(zhi)安裝在氣(qi)動(dong)(dong)工(gong)具本(ben)體上(shang)直(zhi)接與工(gong)件(jian)直(zhi)接接觸的(de)工(gong)具,氣(qi)動(dong)(dong)三聯件(jian)承擔了該項任務。氣(qi)動(dong)(dong)三聯件(jian)主(zhu)要(yao)由(you)氣(qi)壓(ya)表、過濾器(qi)、油霧(wu)器(qi)、調(diao)壓(ya)器(qi)等(deng)部分組成(cheng),其中過濾器(qi)中內置(zhi)濾芯,在使(shi)用一段時間后要(yao)進行維護(hu)清洗、定期更(geng)換;這樣(yang)的(de)壓(ya)縮(suo)空氣(qi)不進行任何處理,直(zhi)接進入氣(qi)動(dong)(dong)馬(ma)達,則將(jiang)導致馬(ma)達壽命大(da)大(da)縮(suo)短,從而致使(shi)整(zheng)把工(gong)具動(dong)(dong)力輸出不足、且(qie)不穩定,易造成(cheng)馬(ma)達等(deng)零部件(jian)連(lian)環損壞的(de)現象(xiang),為此在由(you)管道(dao)輸送的(de)壓(ya)縮(suo)空氣(qi)至氣(qi)動(dong)(dong)工(gong)具之間,必須設置(zhi)壓(ya)縮(suo)空氣(qi)過濾、調(diao)節裝置(zhi),包(bao)括各類(lei)氣(qi)動(dong)(dong)套筒、接桿、轉換接頭、刀頭等(deng);
上述各部分相互依存、相互制約、不能單獨孤立存在實現作業。【詳細>>】
氣動工具優點:
(1)、空氣(qi)作(zuo)為氣(qi)壓傳動的工作(zuo)介(jie)質,取之不(bu)盡(jin),來源方便,用過以(yi)后直接(jie)排入大氣(qi),不(bu)會污染(ran)環境。
(2)、工(gong)作(zuo)(zuo)環(huan)境(jing)適應性好。在易燃、易爆、多塵埃(ai)、輻射、強磁、振(zhen)動、沖(chong)擊等(deng)惡劣環(huan)境(jing)中(zhong),氣壓傳動系(xi)統(tong)工(gong)作(zuo)(zuo)是(shi)安(an)全可(ke)靠(kao)的。
(3)、空氣粘度小(xiao),流動阻力(li)小(xiao),便(bian)于介質集中供應和遠距(ju)離輸送(song)。
(4)、氣動(dong)控(kong)制動(dong)作迅速(su),反應快,可在較短的時間內達(da)到所需的壓(ya)力(li)和速(su)度。
(5)、氣動(dong)元件(jian)結構(gou)簡單,易(yi)于加工(gong),使用壽(shou)命長(chang),可靠性高(gao),易(yi)于實(shi)現(xian)標準化(hua)、系列(lie)化(hua)、通(tong)用化(hua)。
氣動工具缺點:
當然(ran),由(you)于氣(qi)動工(gong)具運用到的(de)氣(qi)動技術是(shi)以壓(ya)縮空氣(qi)作為工(gong)作介質,必然(ran)存在(zai)一些缺點:
(1)、由于空氣(qi)壓縮性大,氣(qi)缸(gang)的動作速(su)度(du)易(yi)隨外(wai)加負載的變化而(er)變化,穩定(ding)性差,給(gei)位置(zhi)和速(su)度(du)控(kong)制帶(dai)來(lai)較大影響。
(2)、目(mu)前氣(qi)動系統(tong)的壓(ya)力(li)級(一般小于0.8MPa)不高(gao),總(zong)的輸出力(li)不大。
(3)、工作介(jie)質(空氣)沒(mei)有潤滑性,系(xi)統中(zhong)必須采取措(cuo)施進(jin)行(xing)給油(you)潤滑。
(4)、噪聲大,一般需要加裝消聲器。【詳細>>】
通常氣(qi)(qi)動工(gong)具(ju)分為:(1)回(hui)轉(zhuan)式氣(qi)(qi)動工(gong)具(ju);(2)沖擊(ji)式氣(qi)(qi)動工(gong)具(ju);(3)氣(qi)(qi)動馬(ma)達、氣(qi)(qi)動機械;這三類(lei)大分類(lei)下(xia)面又(you)有如下(xia)小分類(lei):

1、DIY級(ji)別(bie)的(de),這樣(yang)級(ji)別(bie)的(de)氣動工具(ju)主要是用(yong)于私人使(shi)用(yong),在(zai)氣動工具(ju)的(de)使(shi)用(yong)中占的(de)比例不(bu)(bu)大,工具(ju)本身(shen)就(jiu)不(bu)(bu)具(ju)備長(chang)時(shi)間(jian)操作的(de)質量,適(shi)用(yong)于不(bu)(bu)是常用(yong)但能(neng)在(zai)突(tu)然需要使(shi)用(yong)的(de)時(shi)候(hou)發揮作用(yong)的(de)情況(kuang),使(shi)用(yong)時(shi)長(chang)一般不(bu)(bu)超過2個小時(shi)左右,家具(ju)自用(yong)多。
2、專業級別的(de)(de),就是每天(tian)就使用3、4個小時,有些(xie)是專門針對(dui)某些(xie)行業而(er)設計的(de)(de),這(zhe)樣(yang)的(de)(de)行業有個共同點,每天(tian)都要(yao)用,但(dan)是都在(zai)3到4個小時左右。
3、工(gong)業級,這級別就常出現在工(gong)廠(chang)流水作業了,工(gong)具(ju)本身具(ju)備了耐磨耐損的(de)(de)(de)優(you)點,質量也是比以(yi)上兩(liang)種(zhong)較優(you)。就以(yi)通常的(de)(de)(de)來分析(xi),連續不停的(de)(de)(de)工(gong)作8小(xiao)時(shi),甚至有(you)的(de)(de)(de)分兩(liang)班一天工(gong)作12小(xiao)時(shi),對工(gong)具(ju)是一種(zhong)極大的(de)(de)(de)考驗。
4、品牌,目前氣動工具品牌繁多,一些新客戶因此不知道購買哪一種品牌氣動工具最好。選擇一款好的氣動工具,必須要從以下幾點出發來考慮是否要購買:該氣動工具在目前市場上的排名、該氣動工具使用者的口碑、售后的質量保障服務。【詳細>>】
