平面磨床在工業生產上的應用日趨廣泛，我們對于平面磨床的了解也逐步加深。那對于平面磨床磨削加工的四種裝夾方式，很多人還是不太清楚。平面磨(mo)床生產廠家勤(qin)龍磨床的小編今天就來跟大家介紹一下(xia)它的四(si)種裝(zhuang)夾方(fang)式，幫助大家更好地了解平面磨床。

利用(yong)(yong)大氣(qi)的壓力(li)裝夾薄(bo)片(pian)工(gong)(gong)件(jian)來進(jin)行(xing)磨削(xue)加工(gong)(gong)。其工(gong)(gong)作原理為：夾具體上設有橡膠密(mi)封(feng)圈，把薄(bo)片(pian)工(gong)(gong)件(jian)放在橡膠密(mi)封(feng)圈上，從(cong)而使(shi)工(gong)(gong)件(jian)與夾具體之間形(xing)成密(mi)封(feng)腔。用(yong)(yong)真空泵將室內空氣(qi)從(cong)抽(chou)(chou)氣(qi)孔(kong)抽(chou)(chou)出(chu)，這時工(gong)(gong)件(jian)被夾緊(jin)。由于夾緊(jin)力(li)小(xiao)，可(ke)采用(yong)(yong)圓(yuan)周磨削(xue)方法進(jin)行(xing)磨削(xue)加工(gong)(gong)。當磨削(xue)好薄(bo)片(pian)工(gong)(gong)件(jian)一端平面(mian)后，磨削(xue)薄(bo)片(pian)工(gong)(gong)件(jian)另(ling)一端平面(mian)時，可(ke)采用(yong)(yong)上述方式進(jin)行(xing)，同樣可(ke)得到滿(man)意的結果。

采用(yong)環氧(yang)(yang)(yang)樹脂結(jie)合劑，將薄(bo)(bo)(bo)(bo)片工(gong)(gong)件(jian)(jian)(jian)在(zai)自由狀(zhuang)態下(xia)粘(zhan)(zhan)到一(yi)塊(kuai)平(ping)(ping)(ping)板(ban)(ban)上(shang)。平(ping)(ping)(ping)板(ban)(ban)連(lian)同薄(bo)(bo)(bo)(bo)片一(yi)起放到磁(ci)力(li)(li)(li)吸(xi)(xi)(xi)盤上(shang)。磨(mo)(mo)平(ping)(ping)(ping)薄(bo)(bo)(bo)(bo)片一(yi)端(duan)平(ping)(ping)(ping)面(mian)(mian)后，再(zai)將薄(bo)(bo)(bo)(bo)片工(gong)(gong)件(jian)(jian)(jian)從平(ping)(ping)(ping)板(ban)(ban)上(shang)取下(xia)來，以(yi)磨(mo)(mo)平(ping)(ping)(ping)的(de)一(yi)面(mian)(mian)放到磁(ci)力(li)(li)(li)吸(xi)(xi)(xi)盤上(shang)，再(zai)磨(mo)(mo)削薄(bo)(bo)(bo)(bo)片工(gong)(gong)件(jian)(jian)(jian)的(de)另一(yi)端(duan)平(ping)(ping)(ping)面(mian)(mian)。由于環氧(yang)(yang)(yang)樹脂在(zai)未硬化(hua)之前有(you)流(liu)動性，它(ta)可以(yi)填(tian)平(ping)(ping)(ping)薄(bo)(bo)(bo)(bo)片工(gong)(gong)件(jian)(jian)(jian)與(yu)平(ping)(ping)(ping)板(ban)(ban)之間(jian)(jian)的(de)間(jian)(jian)隙。當環氧(yang)(yang)(yang)樹脂硬化(hua)后，工(gong)(gong)件(jian)(jian)(jian)與(yu)平(ping)(ping)(ping)板(ban)(ban)粘(zhan)(zhan)結(jie)在(zai)一(yi)起，成為(wei)一(yi)個整體(ti)，從而大大增強了工(gong)(gong)件(jian)(jian)(jian)的(de)剛性。在(zai)磁(ci)力(li)(li)(li)吸(xi)(xi)(xi)引(yin)下(xia)，薄(bo)(bo)(bo)(bo)片工(gong)(gong)件(jian)(jian)(jian)不會產生(sheng)夾緊變形，為(wei)磨(mo)(mo)削出(chu)平(ping)(ping)(ping)直平(ping)(ping)(ping)面(mian)(mian)創造(zao)了條件(jian)(jian)(jian)。也可用(yong)厚油(you)脂代替環氧(yang)(yang)(yang)樹脂填(tian)充薄(bo)(bo)(bo)(bo)片工(gong)(gong)件(jian)(jian)(jian)與(yu)磁(ci)力(li)(li)(li)吸(xi)(xi)(xi)盤之間(jian)(jian)的(de)間(jian)(jian)隙，增強工(gong)(gong)件(jian)(jian)(jian)的(de)剛性，同樣(yang)可以(yi)收到良好的(de)效果。

在平(ping)面磨(mo)(mo)床(chuang)上磨(mo)(mo)削(xue)上述薄片工件(jian)時(shi)，采(cai)用彈(dan)性夾緊機構(gou)，使薄片工件(jian)在自由狀態(tai)下實現定位與夾緊。在工件(jian)與磁(ci)性工作臺之(zhi)間墊(dian)一(yi)層0.5mm厚的橡膠，當工件(jian)受(shou)磁(ci)性吸(xi)引力作用時(shi)，橡膠被壓縮，彈(dan)性變(bian)形(xing)變(bian)小(xiao)，從而可磨(mo)(mo)削(xue)出工件(jian)的平(ping)直平(ping)面。反復(fu)磨(mo)(mo)削(xue)幾次(ci)，可滿足(zu)加(jia)工精度要求。
