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(mian)磨床生產廠(chang)家勤(qin)龍磨床(chuang)(chuang)的(de)小編今天(tian)就(jiu)來跟(gen)大家(jia)介(jie)紹一下它的(de)四種(zhong)裝夾(jia)方式，幫助大家(jia)更(geng)好地了解平面磨床(chuang)(chuang)。

利用大氣的壓力(li)裝夾(jia)薄(bo)片(pian)工(gong)(gong)件來進(jin)(jin)行(xing)磨(mo)(mo)(mo)削加工(gong)(gong)。其工(gong)(gong)作原理為(wei)：夾(jia)具體(ti)上(shang)設有(you)橡膠(jiao)密封(feng)圈，把薄(bo)片(pian)工(gong)(gong)件放在橡膠(jiao)密封(feng)圈上(shang)，從而使(shi)工(gong)(gong)件與夾(jia)具體(ti)之間(jian)形成(cheng)密封(feng)腔。用真空(kong)泵將室內空(kong)氣從抽(chou)氣孔抽(chou)出，這時(shi)工(gong)(gong)件被(bei)夾(jia)緊(jin)。由于夾(jia)緊(jin)力(li)小，可采(cai)用圓(yuan)周磨(mo)(mo)(mo)削方法進(jin)(jin)行(xing)磨(mo)(mo)(mo)削加工(gong)(gong)。當磨(mo)(mo)(mo)削好薄(bo)片(pian)工(gong)(gong)件一端(duan)平(ping)面后，磨(mo)(mo)(mo)削薄(bo)片(pian)工(gong)(gong)件另(ling)一端(duan)平(ping)面時(shi)，可采(cai)用上(shang)述方式進(jin)(jin)行(xing)，同(tong)樣可得到滿意的結果。

采用環(huan)氧(yang)樹(shu)脂結(jie)(jie)合劑，將薄(bo)(bo)(bo)片工(gong)件(jian)(jian)(jian)在(zai)自由(you)狀態下粘到一(yi)(yi)(yi)塊平(ping)(ping)(ping)(ping)板(ban)(ban)(ban)上。平(ping)(ping)(ping)(ping)板(ban)(ban)(ban)連同薄(bo)(bo)(bo)片一(yi)(yi)(yi)起放(fang)(fang)到磁(ci)力吸盤上。磨平(ping)(ping)(ping)(ping)薄(bo)(bo)(bo)片一(yi)(yi)(yi)端(duan)平(ping)(ping)(ping)(ping)面后(hou)，再(zai)將薄(bo)(bo)(bo)片工(gong)件(jian)(jian)(jian)從平(ping)(ping)(ping)(ping)板(ban)(ban)(ban)上取下來，以(yi)磨平(ping)(ping)(ping)(ping)的(de)(de)(de)一(yi)(yi)(yi)面放(fang)(fang)到磁(ci)力吸盤上，再(zai)磨削薄(bo)(bo)(bo)片工(gong)件(jian)(jian)(jian)的(de)(de)(de)另一(yi)(yi)(yi)端(duan)平(ping)(ping)(ping)(ping)面。由(you)于環(huan)氧(yang)樹(shu)脂在(zai)未硬(ying)化之前(qian)有流(liu)動性，它可(ke)(ke)以(yi)填(tian)平(ping)(ping)(ping)(ping)薄(bo)(bo)(bo)片工(gong)件(jian)(jian)(jian)與平(ping)(ping)(ping)(ping)板(ban)(ban)(ban)之間的(de)(de)(de)間隙。當環(huan)氧(yang)樹(shu)脂硬(ying)化后(hou)，工(gong)件(jian)(jian)(jian)與平(ping)(ping)(ping)(ping)板(ban)(ban)(ban)粘結(jie)(jie)在(zai)一(yi)(yi)(yi)起，成為一(yi)(yi)(yi)個整體，從而(er)大大增強(qiang)了工(gong)件(jian)(jian)(jian)的(de)(de)(de)剛性。在(zai)磁(ci)力吸引下，薄(bo)(bo)(bo)片工(gong)件(jian)(jian)(jian)不會產生夾緊變(bian)形(xing)，為磨削出平(ping)(ping)(ping)(ping)直平(ping)(ping)(ping)(ping)面創(chuang)造了條件(jian)(jian)(jian)。也可(ke)(ke)用厚(hou)油脂代替環(huan)氧(yang)樹(shu)脂填(tian)充薄(bo)(bo)(bo)片工(gong)件(jian)(jian)(jian)與磁(ci)力吸盤之間的(de)(de)(de)間隙，增強(qiang)工(gong)件(jian)(jian)(jian)的(de)(de)(de)剛性，同樣可(ke)(ke)以(yi)收到良好的(de)(de)(de)效果。

在平面磨(mo)床(chuang)上磨(mo)削上述薄(bo)片工(gong)(gong)件時，采(cai)用彈(dan)性(xing)夾緊機構，使(shi)薄(bo)片工(gong)(gong)件在自(zi)由狀態(tai)下實現定位與夾緊。在工(gong)(gong)件與磁(ci)性(xing)工(gong)(gong)作臺之間墊(dian)一層0.5mm厚的橡(xiang)膠，當工(gong)(gong)件受磁(ci)性(xing)吸引力作用時，橡(xiang)膠被(bei)壓縮，彈(dan)性(xing)變形變小(xiao)，從(cong)而可(ke)磨(mo)削出工(gong)(gong)件的平直平面。反(fan)復磨(mo)削幾(ji)次，可(ke)滿足加工(gong)(gong)精(jing)度要求。
