一:機械的夾緊方式;
用平面磨床附件中的(de)(de)平(ping)(ping)(ping)口鉗(qian)(qian)從磁(ci)臺吸(xi)出薄(bo)片工(gong)件,用(yong)小(xiao)型平(ping)(ping)(ping)口鉗(qian)(qian)吸(xi)出。由(you)于平(ping)(ping)(ping)口鉗(qian)(qian)有(you)一定的(de)(de)高(gao)度,鉗(qian)(qian)口的(de)(de)磁(ci)力很小(xiao)。用(yong)進(jin)給逐漸減少的(de)(de)方法磨(mo)(mo)平(ping)(ping)(ping)一平(ping)(ping)(ping)面(mian)薄(bo)片后取下,此時(shi)將已磨(mo)(mo)好的(de)(de)一平(ping)(ping)(ping)面(mian)放入磁(ci)性(xing)工(gong)作臺,再將另(ling)一平(ping)(ping)(ping)面(mian)薄(bo)片磨(mo)(mo)平(ping)(ping)(ping),反(fan)復(fu)磨(mo)(mo)數次,兩平(ping)(ping)(ping)面(mian)的(de)(de)平(ping)(ping)(ping)度達到要求。
二:真空裝夾方式。
用(yong)空(kong)氣壓(ya)裝(zhuang)夾(jia)緊(jin)薄片(pian)工(gong)(gong)(gong)件(jian)進行研(yan)(yan)磨(mo)加工(gong)(gong)(gong)。該方(fang)(fang)法(fa)的(de)(de)工(gong)(gong)(gong)作原理是在夾(jia)具的(de)(de)具體部分設置橡膠密(mi)封圈,將(jiang)片(pian)狀工(gong)(gong)(gong)件(jian)放置在橡膠密(mi)封圈上(shang),在工(gong)(gong)(gong)件(jian)和夾(jia)具之(zhi)間形成密(mi)封室。利用(yong)真空(kong)泵從抽氣孔(kong)抽出室內空(kong)氣時,夾(jia)緊(jin)工(gong)(gong)(gong)件(jian)。磨(mo)削夾(jia)緊(jin)力小,可采用(yong)環形磨(mo)削法(fa)加工(gong)(gong)(gong)。將(jiang)薄片(pian)工(gong)(gong)(gong)件(jian)的(de)(de)一端面研(yan)(yan)磨(mo)后(hou),再將(jiang)另(ling)一端面研(yan)(yan)磨(mo),利用(yong)上(shang)述方(fang)(fang)法(fa)可對工(gong)(gong)(gong)件(jian)進行研(yan)(yan)磨(mo),同(tong)樣(yang)也可得到滿意的(de)(de)結果。
三:采用臨時措施使薄片工件的剛度增強。
使用環氧(yang)樹(shu)(shu)脂(zhi)結合劑,可(ke)使薄(bo)片(pian)在(zai)自由狀態下粘(zhan)附于平(ping)板上(shang)。板材和(he)薄(bo)片(pian)一起(qi)放(fang)入磁(ci)(ci)性(xing)(xing)吸(xi)盤。把(ba)薄(bo)片(pian)一端磨(mo)平(ping)后(hou),再(zai)(zai)把(ba)薄(bo)片(pian)工(gong)件(jian)(jian)(jian)(jian)從平(ping)板上(shang)取下來,把(ba)磨(mo)平(ping)的一邊(bian)放(fang)到(dao)磁(ci)(ci)性(xing)(xing)吸(xi)盤上(shang),再(zai)(zai)把(ba)另一端的薄(bo)片(pian)工(gong)件(jian)(jian)(jian)(jian)磨(mo)平(ping)。因(yin)為環氧(yang)樹(shu)(shu)脂(zhi)在(zai)未硬化前是流(liu)動的,所以它(ta)能填平(ping)薄(bo)片(pian)和(he)板材之間(jian)的間(jian)隙(xi)(xi)。在(zai)硬化環氧(yang)樹(shu)(shu)脂(zhi)后(hou),將工(gong)件(jian)(jian)(jian)(jian)與平(ping)板結合成一體,從而(er)大大提高了(le)工(gong)件(jian)(jian)(jian)(jian)的剛度。在(zai)磁(ci)(ci)吸(xi)作用下,薄(bo)片(pian)工(gong)件(jian)(jian)(jian)(jian)不(bu)會發生夾緊變形(xing),從而(er)為磨(mo)削加工(gong)平(ping)面創造了(le)條件(jian)(jian)(jian)(jian)。也可(ke)以用厚脂(zhi)代替(ti)環氧(yang)樹(shu)(shu)脂(zhi)填充(chong)薄(bo)片(pian)工(gong)件(jian)(jian)(jian)(jian)和(he)磁(ci)(ci)吸(xi)盤之間(jian)的間(jian)隙(xi)(xi),提高工(gong)件(jian)(jian)(jian)(jian)的剛度,同樣可(ke)以取得良好的效果。
四:彈性墊片的夾緊方式。
對上述薄片工件在平面磨床上進行磨(mo)削時,采(cai)用彈性夾緊(jin)機構,使其在自由(you)狀態下進行定位夾緊(jin)。工件(jian)(jian)與磁性工作臺之(zhi)間用0.5mm厚的(de)(de)橡膠墊墊,當工件(jian)(jian)被磁力吸引時,橡膠會被擠壓,彈性變形減(jian)小,從(cong)而(er)磨(mo)出(chu)工件(jian)(jian)的(de)(de)平直平面(mian)。多(duo)次多(duo)次的(de)(de)研磨(mo),可以滿(man)足(zu)加工精度的(de)(de)要(yao)求(qiu)。
