液壓缸的介紹
液(ye)壓(ya)(ya)(ya)缸是將(jiang)液(ye)壓(ya)(ya)(ya)能轉變為機(ji)(ji)械(xie)能的(de)、做直線往復(fu)運(yun)動(dong)（或擺(bai)動(dong)運(yun)動(dong)）的(de)液(ye)壓(ya)(ya)(ya)執行元件。它結構簡單、工作可(ke)靠。用(yong)它來實現往復(fu)運(yun)動(dong)時，可(ke)免去(qu)減速(su)裝(zhuang)(zhuang)置(zhi)，并且沒有(you)傳(chuan)動(dong)間隙(xi)，運(yun)動(dong)平穩，因(yin)此在(zai)各(ge)種機(ji)(ji)械(xie)的(de)液(ye)壓(ya)(ya)(ya)系統(tong)中得到廣泛(fan)應(ying)用(yong)。液(ye)壓(ya)(ya)(ya)缸輸(shu)出(chu)力(li)和活塞(sai)有(you)效面積及其(qi)兩邊的(de)壓(ya)(ya)(ya)差(cha)成正比；液(ye)壓(ya)(ya)(ya)缸基本(ben)上(shang)由缸筒和缸蓋(gai)、活塞(sai)和活塞(sai)桿、密(mi)封裝(zhuang)(zhuang)置(zhi)、緩(huan)沖裝(zhuang)(zhuang)置(zhi)與排氣(qi)裝(zhuang)(zhuang)置(zhi)組成。緩(huan)沖裝(zhuang)(zhuang)置(zhi)與排氣(qi)裝(zhuang)(zhuang)置(zhi)視具體應(ying)用(yong)場合而定，其(qi)他裝(zhuang)(zhuang)置(zhi)則很重要。
液壓缸(gang)結構基本(ben)上可(ke)以分為缸(gang)筒和缸(gang)蓋(gai)、活塞(sai)和活塞(sai)桿、密(mi)封裝(zhuang)置(zhi)、緩沖裝(zhuang)置(zhi)和排氣裝(zhuang)置(zhi)五(wu)個部分。今天威(wei)海力建小編著重帶著大家了(le)解(jie)一下缸(gang)筒和缸(gang)蓋(gai)。
缸(gang)筒和缸(gang)蓋
一般來(lai)說(shuo)，缸筒(tong)和(he)缸蓋的(de)(de)結(jie)構(gou)形(xing)式(shi)和(he)其使用(yong)(yong)的(de)(de)材料有關。工作壓力(li)p＜10MPa時(shi)(shi)，使用(yong)(yong)鑄(zhu)鐵；p＜20MPa時(shi)(shi)，使用(yong)(yong)無縫鋼(gang)(gang)管(guan)；p＞20MPa時(shi)(shi)，使用(yong)(yong)鑄(zhu)鋼(gang)(gang)或鍛(duan)鋼(gang)(gang)。法蘭連(lian)(lian)(lian)接式(shi)，結(jie)構(gou)簡(jian)單，容(rong)(rong)易(yi)加(jia)工，也容(rong)(rong)易(yi)裝(zhuang)拆(chai)(chai)(chai)，但外(wai)形(xing)尺寸和(he)重(zhong)(zhong)(zhong)量(liang)都(dou)較(jiao)大(da)(da)，常(chang)用(yong)(yong)于鑄(zhu)鐵制(zhi)的(de)(de)缸筒(tong)上(shang)。半(ban)環(huan)連(lian)(lian)(lian)接式(shi)，它(ta)(ta)(ta)的(de)(de)缸筒(tong)壁部因開了環(huan)形(xing)槽(cao)而削弱了強度(du)，為(wei)此有時(shi)(shi)要(yao)加(jia)厚(hou)缸壁，它(ta)(ta)(ta)容(rong)(rong)易(yi)加(jia)工和(he)裝(zhuang)拆(chai)(chai)(chai)，重(zhong)(zhong)(zhong)量(liang)較(jiao)輕，常(chang)用(yong)(yong)于無縫鋼(gang)(gang)管(guan)或鍛(duan)鋼(gang)(gang)制(zhi)的(de)(de)缸筒(tong)上(shang)。螺紋連(lian)(lian)(lian)接式(shi)，它(ta)(ta)(ta)的(de)(de)缸筒(tong)端部結(jie)構(gou)復雜，外(wai)徑(jing)加(jia)工時(shi)(shi)要(yao)求(qiu)保證內外(wai)徑(jing)同心，裝(zhuang)拆(chai)(chai)(chai)要(yao)使用(yong)(yong)工具，它(ta)(ta)(ta)的(de)(de)外(wai)形(xing)尺寸和(he)重(zhong)(zhong)(zhong)量(liang)都(dou)較(jiao)小(xiao)(xiao)，常(chang)用(yong)(yong)于無縫鋼(gang)(gang)管(guan)或鑄(zhu)鋼(gang)(gang)制(zhi)的(de)(de)缸筒(tong)上(shang)。拉桿連(lian)(lian)(lian)接式(shi)，結(jie)構(gou)的(de)(de)通(tong)用(yong)(yong)性大(da)(da)，容(rong)(rong)易(yi)加(jia)工和(he)裝(zhuang)拆(chai)(chai)(chai)，但外(wai)形(xing)尺寸較(jiao)大(da)(da)，且(qie)較(jiao)重(zhong)(zhong)(zhong)。焊接連(lian)(lian)(lian)接式(shi)，結(jie)構(gou)簡(jian)單，尺寸小(xiao)(xiao)，但缸底處內徑(jing)不(bu)易(yi)加(jia)工，且(qie)可(ke)能引起變(bian)形(xing)。
零部件加(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度(du)(du)(du)的影響問(wen)題(ti)，在液壓缸的制造(zao)過程中應嚴格控制缸體內(nei)壁(bi)(bi)和(he)活塞(sai)桿(gan)表面(mian)加(jia)工(gong)(gong)(gong)(gong)(gong)精(jing)度(du)(du)(du)，特(te)別是(shi)幾何(he)精(jing)度(du)(du)(du)，尤其(qi)直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)(du)是(shi)關鍵，在國內(nei)加(jia)工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝中，活塞(sai)桿(gan)表面(mian)的加(jia)工(gong)(gong)(gong)(gong)(gong)基(ji)本上是(shi)車后(hou)磨(mo)削(xue)，保證直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)(du)問(wen)題(ti)不大，但對(dui)于缸體內(nei)壁(bi)(bi)的加(jia)工(gong)(gong)(gong)(gong)(gong)，其(qi)加(jia)工(gong)(gong)(gong)(gong)(gong)方法很多，有(you)鏜削(xue)-滾(gun)壓、鏜削(xue)-珩(heng)磨(mo)、直(zhi)(zhi)接(jie)珩(heng)磨(mo)等，但由于國內(nei)材(cai)料的基(ji)礎水平較國外有(you)差距，管(guan)材(cai)坯(pi)料直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)(du)差，壁(bi)(bi)厚不均勻(yun)、硬度(du)(du)(du)不均勻(yun)等因(yin)素，往(wang)往(wang)直(zhi)(zhi)接(jie)影響缸體內(nei)壁(bi)(bi)加(jia)工(gong)(gong)(gong)(gong)(gong)后(hou)的直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)(du)，因(yin)此建(jian)議采用鏜削(xue)-滾(gun)壓、鏜削(xue)-珩(heng)磨(mo)工(gong)(gong)(gong)(gong)(gong)藝，如直(zhi)(zhi)接(jie)珩(heng)磨(mo)，則必須首先(xian)提高管(guan)材(cai)坯(pi)料的直(zhi)(zhi)線(xian)(xian)(xian)度(du)(du)(du)。

在允許(xu)的情(qing)況(kuang)下(xia)(xia)(xia)，液(ye)壓缸(gang)的缸(gang)體(ti)壁厚安全系數盡量選大(da)一些，使缸(gang)體(ti)厚壁增加(jia)，特別(bie)是高壓工況(kuang)下(xia)(xia)(xia)使用(yong)的油(you)缸(gang)，以減小油(you)壓下(xia)(xia)(xia)的缸(gang)體(ti)變形，變形后的缸(gang)體(ti)也會(hui)引起液(ye)壓缸(gang)低(di)速爬行。
