平面磨床的分類


按主軸布局及工作臺(tai)形(xing)狀(zhuang)的組合(he),普通平面磨(mo)床可分為(wei)下列四(si)類:


1、臥軸矩臺式平面磨床;在這種機床中,工(gong)件由矩形電磁工(gong)作臺吸住。砂(sha)輪(lun)作旋轉(zhuan)主運(yun)動(dong),工(gong)作臺作縱向(xiang)往復運(yun)動(dong),砂(sha)輪(lun)架作間歇的豎直切入運(yun)動(dong)和橫(heng)向(xiang)進給運(yun)動(dong)。


2、立軸(zhou)矩臺式(shi)平面(mian)磨床;在這種(zhong)機床上,砂輪作旋轉主運(yun)動,矩形(xing)工(gong)作臺作縱向往復運(yun)動,砂輪架作間歇的(de)豎直切入運(yun)動。


3、立軸(zhou)圓(yuan)臺(tai)式平面磨床;在(zai)這種(zhong)機床上(shang),砂輪(lun)作(zuo)旋轉(zhuan)主運(yun)動(dong)(dong)(dong)圓(yuan)工作(zuo)臺(tai)旋轉(zhuan)作(zuo)圓(yuan)周進給運(yun)動(dong)(dong)(dong),砂輪(lun)架作(zuo)間歇的豎直切(qie)入(ru)運(yun)動(dong)(dong)(dong)。


4、臥(wo)軸(zhou)圓臺式平面(mian)磨床;在這種機床上,砂(sha)輪作旋(xuan)轉主運動(dong),圓工(gong)作臺旋(xuan)轉作圓周進給運動(dong),砂(sha)輪架作連續(xu)的徑向進給運動(dong)和(he)間歇的豎(shu)直(zhi)切(qie)入運動(dong)。此外(wai),工(gong)作臺的回轉中心線(xian)可以調整(zheng)至(zhi)傾斜位(wei)置,以便磨削錐面(mian)。


   上述四種平面(mian)(mian)(mian)(mian)磨(mo)床中,用砂輪端面(mian)(mian)(mian)(mian)磨(mo)削的(de)(de)平面(mian)(mian)(mian)(mian)磨(mo)床與(yu)用輪緣磨(mo)削的(de)(de)平面(mian)(mian)(mian)(mian)磨(mo)床相(xiang)比(bi),由(you)于(yu)端面(mian)(mian)(mian)(mian)磨(mo)削的(de)(de)砂輪直(zhi)徑(jing)(jing)往(wang)往(wang)比(bi)較(jiao)大(da),能同(tong)時(shi)磨(mo)出工件的(de)(de)全寬,磨(mo)削面(mian)(mian)(mian)(mian)積較(jiao)大(da),所以,生產率較(jiao)高。但是,端面(mian)(mian)(mian)(mian)磨(mo)削時(shi),砂輪和(he)工件表面(mian)(mian)(mian)(mian)是成(cheng)弧形(xing)線或面(mian)(mian)(mian)(mian)接觸,接觸面(mian)(mian)(mian)(mian)積大(da),冷卻困難,切屑也不(bu)(bu)易排除(chu),所以,加工精度(du)和(he)表面(mian)(mian)(mian)(mian)粗糙度(du)稍差。圓(yuan)(yuan)臺(tai)(tai)式(shi)(shi)平面(mian)(mian)(mian)(mian)磨(mo)床與(yu)矩臺(tai)(tai)式(shi)(shi)平面(mian)(mian)(mian)(mian)磨(mo)床相(xiang)比(bi)較(jiao),圓(yuan)(yuan)臺(tai)(tai)式(shi)(shi)的(de)(de)生產率稍高些,這是由(you)于(yu)圓(yuan)(yuan)臺(tai)(tai)式(shi)(shi)是連續進給(gei),而矩臺(tai)(tai)式(shi)(shi)有換(huan)向時(shi)間損失(shi)。但是,圓(yuan)(yuan)臺(tai)(tai)式(shi)(shi)只適(shi)于(yu)磨(mo)削小零(ling)件和(he)大(da)直(zhi)徑(jing)(jing)的(de)(de)環(huan)形(xing)零(ling)件端面(mian)(mian)(mian)(mian),不(bu)(bu)能磨(mo)削長零(ling)件。而矩臺(tai)(tai)式(shi)(shi)可方便地磨(mo)削各(ge)種常用零(ling)件,包括直(zhi)徑(jing)(jing)小于(yu)矩臺(tai)(tai)寬度(du)的(de)(de)環(huan)形(xing)零(ling)件。
