μm的軸向峰到峰運(yùn)動(dòng)。超聲波換能器是精密設(shè)備，應(yīng)小心處理。2 超聲波變幅桿：變幅桿有兩個(gè)作用。其主要作用是放大換能器端部產(chǎn)生的機(jī)械振動(dòng)并將振動(dòng)傳給焊頭。另一作用是提供固定套件于焊接壓力機(jī)上的位置。在換能器施加超聲能量時(shí)，變幅桿也膨脹和收縮。與焊接套件中的其它零件一樣，變幅桿是調(diào)諧裝置，因而它也必須在特定頻率共振以便將超聲能量從換能器傳至焊頭。為了有效地發(fā)揮作用，變幅桿必須是超聲波在其制造材質(zhì)中的半波長(zhǎng)或半波長(zhǎng)的整數(shù)倍。一般為半波長(zhǎng)。</p><p
