吸盤可(ke)以有很多種，我們來看一下。

一(yi)種利用內(nei)外大氣壓力(li)的差別,吸(xi)附在物體(ti)上的一(yi)種掛件,或者是抓取物體(ti)的一(yi)種工具(ju)。

另一種是磁(ci)力(li)吸(xi)盤,專門用于對(dui)鐵磁(ci)性物質的吸(xi)附(fu)和(he)固定, 大多數應用在機械加(jia)工(gong)等領域.

利(li)用吸(xi)(xi)(xi)(xi)力(li)夾持工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)(de)機床(chuang)(chuang)附(fu)件(jian)(jian)(jian)。較常用的(de)(de)吸(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)是磁(ci)(ci)力(li)吸(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)，一般為矩形或圓(yuan)盤(pan)(pan)(pan)形。它利(li)用磁(ci)(ci)力(li)將鐵磁(ci)(ci)性工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)吸(xi)(xi)(xi)(xi)緊(jin)，用于平(ping)面磨床(chuang)(chuang)，也用于銑(xian)床(chuang)(chuang)和車床(chuang)(chuang), 數控機床(chuang)(chuang), 加工(gong)(gong)(gong)(gong)中心等。吸(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)按(an)磁(ci)(ci)力(li)來源(yuan)分有(you)電(dian)磁(ci)(ci)吸(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)和永(yong)磁(ci)(ci)吸(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)兩類。①電(dian)磁(ci)(ci)吸(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)：體(ti)(ti)內裝(zhuang)有(you)多組線(xian)圈(quan)（圖1）,通(tong)入直流電(dian)產(chan)生磁(ci)(ci)場，吸(xi)(xi)(xi)(xi)緊(jin)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)；切斷電(dian)源(yuan)，磁(ci)(ci)場消失，松開工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)。②永(yong)磁(ci)(ci)吸(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)：體(ti)(ti)內裝(zhuang)有(you)整齊(qi)排列(lie)并被不導(dao)磁(ci)(ci)材料隔開的(de)(de)永(yong)久磁(ci)(ci)鐵（圖2）,當磁(ci)(ci)鐵與吸(xi)(xi)(xi)(xi)盤(pan)(pan)(pan)面板(ban)上(shang)的(de)(de)導(dao)磁(ci)(ci)體(ti)(ti)對準時,磁(ci)(ci)力(li)線(xian)通(tong)過工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)形成閉合回(hui)路(lu),吸(xi)(xi)(xi)(xi)緊(jin)工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)；當轉(zhuan)動手柄(bing)使(shi)磁(ci)(ci)鐵與導(dao)磁(ci)(ci)體(ti)(ti)錯開,磁(ci)(ci)力(li)線(xian)不再通(tong)過工(gong)(gong)(gong)(gong)件(jian)(jian)(jian),即(ji)可卸下工(gong)(gong)(gong)(gong)件(jian)(jian)(jian)。

以(yi)前的(de)永磁(ci)(ci)(ci)吸(xi)(xi)(xi)盤(pan)(pan)(pan)吸(xi)(xi)(xi)力(li)比(bi)電(dian)(dian)磁(ci)(ci)(ci)吸(xi)(xi)(xi)盤(pan)(pan)(pan)小. 但(dan)是現在(zai)磁(ci)(ci)(ci)性材料性能的(de)提高(gao)和設計生產工藝的(de)提高(gao), 永磁(ci)(ci)(ci)吸(xi)(xi)(xi)盤(pan)(pan)(pan)的(de)吸(xi)(xi)(xi)力(li)可以(yi)做得比(bi)電(dian)(dian)磁(ci)(ci)(ci)吸(xi)(xi)(xi)盤(pan)(pan)(pan)大. 永磁(ci)(ci)(ci)吸(xi)(xi)(xi)盤(pan)(pan)(pan)不因通電(dian)(dian)而(er)發熱和變(bian)形，故不影響加工精度(du)。但(dan)是也會因為磁(ci)(ci)(ci)致(zhi)伸縮有(you)很(hen)微小的(de)變(bian)形. 另有(you)利(li)用真空吸(xi)(xi)(xi)力(li)的(de)真空吸(xi)(xi)(xi)盤(pan)(pan)(pan)和利(li)用工件與臺面間的(de)正負靜電(dian)(dian)荷相吸(xi)(xi)(xi)的(de)靜電(dian)(dian)吸(xi)(xi)(xi)盤(pan)(pan)(pan)。這些吸(xi)(xi)(xi)盤(pan)(pan)(pan)吸(xi)(xi)(xi)力(li)都較小，只適用于(yu)吸(xi)(xi)(xi)緊薄壁工件或非磁(ci)(ci)(ci)性工件等(deng)。

你需(xu)要(yao)什(shen)么樣的(de)四川吸盤，你清楚(chu)嗎。
