安裝氣門車床時應該怎么做?
氣門車床裝夾時我(wo)們(men)知道該(gai)怎么(me)做嗎?遇(yu)到此問題時不(bu)要驚慌(huang)。我(wo)們(men)擁(yong)有專業技術精湛的工程師,確保(bao)及時完(wan)善的售(shou)前售(shou)后服務。那么(me)讓我(wo)們(men)介紹一些方法。
(1)鉆(zhan)孔(kong)(kong),在(zai)(zai)較大(da)工件(jian)(jian)上(shang)鉆(zhan)孔(kong)(kong),工件(jian)(jian)可(ke)直(zhi)接夾(jia)(jia)緊(jin)在(zai)(zai)工作(zuo)臺(tai)(tai)面上(shang),用壓板螺栓夾(jia)(jia)緊(jin)工件(jian)(jian)。夾(jia)(jia)緊(jin)位置(zhi)(zhi)(zhi)應(ying)(ying)(ying)合理對稱。為(wei)避免損(sun)壞(huai)工作(zuo)臺(tai)(tai)面,可(ke)將(jiang)鉆(zhan)孔(kong)(kong)位置(zhi)(zhi)(zhi)置(zhi)(zhi)(zhi)于(yu)工作(zuo)臺(tai)(tai)面的(de)T型(xing)槽位置(zhi)(zhi)(zhi)。如(ru)果孔(kong)(kong)的(de)直(zhi)徑大(da)于(yu)直(zhi)槽的(de)寬度,則應(ying)(ying)(ying)在(zai)(zai)工件(jian)(jian)和工作(zuo)臺(tai)(tai)之間(jian)放(fang)置(zhi)(zhi)(zhi)一個平行(xing)墊。堵塞。注(zhu)意機器(qi)床(chuang)墊放(fang)入坐墊后,壓板的(de)夾(jia)(jia)緊(jin)位置(zhi)(zhi)(zhi)應(ying)(ying)(ying)落(luo)在(zai)(zai)坐墊上(shang)。通常采用預劃、沖(chong)孔(kong)(kong)的(de)方法求出孔(kong)(kong)的(de)基位,通過比較精確的(de)孔(kong)(kong),可(ke)以畫(hua)出試鉆(zhan)錐坑的(de)基準圓(yuan)。
(2)在(zai)(zai)軸上鉆徑(jing)向孔,在(zai)(zai)軸類(lei)零件(jian)(jian)的(de)(de)圓柱面(mian)上鉆孔,將工(gong)(gong)件(jian)(jian)夾緊(jin)在(zai)(zai)V形(xing)(xing)塊(kuai)的(de)(de)V形(xing)(xing)槽中。對于較(jiao)長的(de)(de)工(gong)(gong)件(jian)(jian),請使(shi)用等高的(de)(de)V形(xing)(xing)塊(kuai)。壓板和(he)螺栓(shuan)裝置應(ying)合理(li)。壓板的(de)(de)夾緊(jin)點應(ying)落在(zai)(zai)V形(xing)(xing)槽內。裝夾工(gong)(gong)件(jian)(jian)時,注意兩個V形(xing)(xing)塊(kuai)的(de)(de)V形(xing)(xing)槽面(mian)。圓周面(mian)接觸定(ding)位,夾緊(jin)操作應(ying)使(shi)兩壓板依次逐漸夾緊(jin)。孔的(de)(de)軸向位置由直(zhi)線確定(ding),孔的(de)(de)徑(jing)向位置通常(chang)通過在(zai)(zai)端面(mian)上畫(hua)十字線來校正。鉆孔時,應(ying)使(shi)用底鉆用樣品(pin)沖頭(tou)鉆出錐形(xing)(xing)孔,
(3)鉆等孔(kong),在工(gong)件(jian)上(shang)(shang)鉆等孔(kong),將(jiang)機(ji)床裝(zhuang)夾(jia)(jia)在分度頭或換向工(gong)作臺(tai)(tai)上(shang)(shang)。矩(ju)形(xing)工(gong)件(jian)可(ke)(ke)用四(si)爪單動卡盤夾(jia)(jia)緊。將(jiang)四(si)爪丹東(dong)卡盤夾(jia)(jia)緊在反轉(zhuan)(zhuan)工(gong)作臺(tai)(tai)上(shang)(shang),然(ran)(ran)后將(jiang)反轉(zhuan)(zhuan)工(gong)作臺(tai)(tai)夾(jia)(jia)緊在銑床上(shang)(shang)進行加(jia)工(gong)。加(jia)工(gong)完一個孔(kong)后,可(ke)(ke)以(yi)(yi)旋轉(zhuan)(zhuan)一個等角,然(ran)(ran)后就可(ke)(ke)以(yi)(yi)鉆一個孔(kong)了。孔(kong)的(de)散圓直徑尺(chi)寸可(ke)(ke)以(yi)(yi)通過預(yu)先標(biao)記(ji)來確定。
(4)鉆(zhan)通孔(kong)。在(zai)較小的(de)矩形(xing)工(gong)件(jian)(jian)(jian)上鉆(zhan)通孔(kong)。可選(xuan)用(yong)機床用(yong)平(ping)頭虎鉗(qian)(qian)夾住工(gong)件(jian)(jian)(jian),在(zai)工(gong)件(jian)(jian)(jian)與(yu)機床平(ping)頭虎鉗(qian)(qian)導軌定(ding)位(wei)(wei)面之間(jian)放置平(ping)行墊(dian)塊。注意(yi)平(ping)行墊(dian)應高度相(xiang)同(tong)且位(wei)(wei)于鉆(zhan)孔(kong)方向的(de)兩(liang)側。孔(kong)和(he)基準面的(de)方位(wei)(wei)標(biao)度是(shi)通過(guo)預先標(biao)記和(he)校對確定(ding)的(de)。
