吸盤可以有(you)很(hen)多(duo)種(zhong)，我們來看一下。

一(yi)種利用內外大氣(qi)壓力的(de)差別,吸附在物體(ti)上的(de)一(yi)種掛件,或者是抓取物體(ti)的(de)一(yi)種工具。

 另一種是(shi)磁力吸盤(pan),專門(men)用于對鐵磁性(xing)物(wu)質的吸附(fu)和固定, 大多數應用在機械(xie)加工等領域.

利用(yong)吸(xi)力(li)夾(jia)持工(gong)件(jian)(jian)(jian)(jian)的(de)機床(chuang)附件(jian)(jian)(jian)(jian)。較常用(yong)的(de)吸(xi)盤(pan)(pan)是(shi)磁(ci)(ci)(ci)(ci)力(li)吸(xi)盤(pan)(pan)，一般為矩形(xing)或圓盤(pan)(pan)形(xing)。它(ta)利用(yong)磁(ci)(ci)(ci)(ci)力(li)將鐵磁(ci)(ci)(ci)(ci)性工(gong)件(jian)(jian)(jian)(jian)吸(xi)緊，用(yong)于(yu)平面(mian)磨床(chuang)，也用(yong)于(yu)銑床(chuang)和車床(chuang), 數(shu)控機床(chuang), 加工(gong)中心(xin)等。吸(xi)盤(pan)(pan)按磁(ci)(ci)(ci)(ci)力(li)來源分有電(dian)磁(ci)(ci)(ci)(ci)吸(xi)盤(pan)(pan)和永磁(ci)(ci)(ci)(ci)吸(xi)盤(pan)(pan)兩類(lei)。①電(dian)磁(ci)(ci)(ci)(ci)吸(xi)盤(pan)(pan)：體內(nei)裝有多組線圈（圖1）,通(tong)入直(zhi)流電(dian)產生磁(ci)(ci)(ci)(ci)場，吸(xi)緊工(gong)件(jian)(jian)(jian)(jian)；切(qie)斷電(dian)源，磁(ci)(ci)(ci)(ci)場消失(shi)，松開(kai)工(gong)件(jian)(jian)(jian)(jian)。②永磁(ci)(ci)(ci)(ci)吸(xi)盤(pan)(pan)：體內(nei)裝有整(zheng)齊排(pai)列并被不導(dao)磁(ci)(ci)(ci)(ci)材料隔(ge)開(kai)的(de)永久磁(ci)(ci)(ci)(ci)鐵（圖2）,當磁(ci)(ci)(ci)(ci)鐵與吸(xi)盤(pan)(pan)面(mian)板上的(de)導(dao)磁(ci)(ci)(ci)(ci)體對準(zhun)時(shi),磁(ci)(ci)(ci)(ci)力(li)線通(tong)過工(gong)件(jian)(jian)(jian)(jian)形(xing)成閉合回路,吸(xi)緊工(gong)件(jian)(jian)(jian)(jian)；當轉動(dong)手(shou)柄使磁(ci)(ci)(ci)(ci)鐵與導(dao)磁(ci)(ci)(ci)(ci)體錯開(kai),磁(ci)(ci)(ci)(ci)力(li)線不再通(tong)過工(gong)件(jian)(jian)(jian)(jian),即可卸下工(gong)件(jian)(jian)(jian)(jian)。

以(yi)前的(de)永磁吸(xi)(xi)盤(pan)吸(xi)(xi)力(li)比電(dian)(dian)磁吸(xi)(xi)盤(pan)小. 但是現在磁性材(cai)料性能的(de)提高和(he)設(she)計生(sheng)產工(gong)(gong)藝的(de)提高, 永磁吸(xi)(xi)盤(pan)的(de)吸(xi)(xi)力(li)可以(yi)做得比電(dian)(dian)磁吸(xi)(xi)盤(pan)大. 永磁吸(xi)(xi)盤(pan)不因通電(dian)(dian)而(er)發熱和(he)變形(xing)，故不影響加工(gong)(gong)精度。但是也會因為磁致伸縮有很微小的(de)變形(xing). 另有利用真空(kong)吸(xi)(xi)力(li)的(de)真空(kong)吸(xi)(xi)盤(pan)和(he)利用工(gong)(gong)件與臺(tai)面間(jian)的(de)正負(fu)靜(jing)電(dian)(dian)荷相吸(xi)(xi)的(de)靜(jing)電(dian)(dian)吸(xi)(xi)盤(pan)。這些吸(xi)(xi)盤(pan)吸(xi)(xi)力(li)都較小，只適用于吸(xi)(xi)緊薄壁工(gong)(gong)件或非(fei)磁性工(gong)(gong)件等。

你需要什(shen)么樣(yang)的四川吸盤(pan)，你清楚嗎(ma)。
