吸盤可以有很多種(zhong)，我們來看(kan)一(yi)下。

一種利(li)用(yong)內(nei)外大氣壓力的差別,吸附在物體(ti)上的一種掛(gua)件(jian),或者是抓(zhua)取(qu)物體(ti)的一種工具。

另一種(zhong)是磁(ci)力吸盤,專(zhuan)門(men)用(yong)于對鐵磁(ci)性(xing)物質的吸附(fu)和固定, 大(da)多數應用(yong)在機械加工(gong)等(deng)領域.

利(li)用吸(xi)(xi)(xi)力夾持工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)的(de)機床(chuang)(chuang)附(fu)件(jian)(jian)(jian)。較常(chang)用的(de)吸(xi)(xi)(xi)盤(pan)(pan)(pan)是磁(ci)(ci)(ci)力吸(xi)(xi)(xi)盤(pan)(pan)(pan)，一般為矩形或(huo)圓盤(pan)(pan)(pan)形。它利(li)用磁(ci)(ci)(ci)力將鐵磁(ci)(ci)(ci)性工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)吸(xi)(xi)(xi)緊(jin)，用于平面磨床(chuang)(chuang)，也用于銑床(chuang)(chuang)和車床(chuang)(chuang), 數控機床(chuang)(chuang), 加工(gong)(gong)(gong)(gong)(gong)中心等。吸(xi)(xi)(xi)盤(pan)(pan)(pan)按磁(ci)(ci)(ci)力來源分有(you)電(dian)磁(ci)(ci)(ci)吸(xi)(xi)(xi)盤(pan)(pan)(pan)和永磁(ci)(ci)(ci)吸(xi)(xi)(xi)盤(pan)(pan)(pan)兩類。①電(dian)磁(ci)(ci)(ci)吸(xi)(xi)(xi)盤(pan)(pan)(pan)：體內裝(zhuang)有(you)多(duo)組線圈（圖1）,通入直流電(dian)產生磁(ci)(ci)(ci)場，吸(xi)(xi)(xi)緊(jin)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)；切斷電(dian)源，磁(ci)(ci)(ci)場消失，松開工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)。②永磁(ci)(ci)(ci)吸(xi)(xi)(xi)盤(pan)(pan)(pan)：體內裝(zhuang)有(you)整(zheng)齊(qi)排列(lie)并被(bei)不(bu)導(dao)磁(ci)(ci)(ci)材料隔(ge)開的(de)永久磁(ci)(ci)(ci)鐵（圖2）,當磁(ci)(ci)(ci)鐵與吸(xi)(xi)(xi)盤(pan)(pan)(pan)面板(ban)上的(de)導(dao)磁(ci)(ci)(ci)體對準時,磁(ci)(ci)(ci)力線通過工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)形成閉合回(hui)路,吸(xi)(xi)(xi)緊(jin)工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)；當轉動手柄使磁(ci)(ci)(ci)鐵與導(dao)磁(ci)(ci)(ci)體錯(cuo)開,磁(ci)(ci)(ci)力線不(bu)再通過工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian),即(ji)可卸下工(gong)(gong)(gong)(gong)(gong)件(jian)(jian)(jian)。

以(yi)前(qian)的永(yong)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)吸(xi)(xi)(xi)(xi)(xi)力(li)比電(dian)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)小(xiao). 但(dan)是(shi)現在磁(ci)性材料性能的提(ti)高(gao)和(he)設計生產工(gong)(gong)藝(yi)的提(ti)高(gao), 永(yong)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)的吸(xi)(xi)(xi)(xi)(xi)力(li)可以(yi)做(zuo)得比電(dian)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)大. 永(yong)磁(ci)吸(xi)(xi)(xi)(xi)(xi)盤(pan)不因通電(dian)而發熱(re)和(he)變(bian)形(xing)(xing)，故不影響加工(gong)(gong)精度(du)。但(dan)是(shi)也會因為(wei)磁(ci)致伸縮有(you)很(hen)微(wei)小(xiao)的變(bian)形(xing)(xing). 另有(you)利用真空(kong)吸(xi)(xi)(xi)(xi)(xi)力(li)的真空(kong)吸(xi)(xi)(xi)(xi)(xi)盤(pan)和(he)利用工(gong)(gong)件(jian)(jian)與臺面間(jian)的正負靜電(dian)荷相(xiang)吸(xi)(xi)(xi)(xi)(xi)的靜電(dian)吸(xi)(xi)(xi)(xi)(xi)盤(pan)。這些吸(xi)(xi)(xi)(xi)(xi)盤(pan)吸(xi)(xi)(xi)(xi)(xi)力(li)都較(jiao)小(xiao)，只適用于吸(xi)(xi)(xi)(xi)(xi)緊薄(bo)壁工(gong)(gong)件(jian)(jian)或非磁(ci)性工(gong)(gong)件(jian)(jian)等。

你需要什么樣的四川吸盤，你清楚嗎。
