所述的(de)(de)爪型(xing)轉(zhuan)臂4-8的(de)(de)下表(biao)面通過連接(jie)孔(kong)連接(jie)有上(shang)定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)(wei)塊(kuai)4-2，上(shang)定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)(wei)塊(kuai)4-2的(de)(de)下定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)(wei)面與下定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)(wei)塊(kuai)、豎向鋼(gang)絲(si)定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)(wei)塊(kuai)位(wei)(wei)(wei)(wei)(wei)置相對。豎向鋼(gang)絲(si)定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)(wei)塊(kuai)4-5、下定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)(wei)塊(kuai)4-4和彎曲(qu)鋼(gang)絲(si)定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)(wei)塊(kuai)4-6的(de)(de)上(shang)表(biao)面設(she)置有鋼(gang)絲(si)定(ding)(ding)(ding)(ding)位(wei)(wei)(wei)(wei)(wei)凹槽。上(shang)述部件配合(he)使用(yong)，用(yong)于夾緊組合(he)式多種鋼(gang)絲(si)位(wei)(wei)(wei)(wei)(wei)置。

所述的爪型(xing)轉臂4-8與上(shang)定(ding)位塊4-2之(zhi)間(jian)設置(zhi)有間(jian)隙調整墊4-7。通過間(jian)隙調整墊4-7能夠(gou)微調上(shang)定(ding)位塊4-2的高度，增強設備的適用性能。

所述的(de)爪型轉臂(bei)4-8F型上(shang)端的(de)橫向臂(bei)的(de)自由頂在靠(kao)背骨架(jia)待焊接圓管(guan)的(de)內(nei)(nei)側面，同時固定(ding)鋼絲和圓管(guan)的(de)位置。在有(you)限的(de)空間(jian)內(nei)(nei)實現多定(ding)位面，對(dui)待加工(gong)零(ling)件進行定(ding)位和夾緊。

使用時(shi)，通過旋(xuan)(xuan)轉(zhuan)(zhuan)氣缸II4-1帶(dai)動(dong)爪(zhua)型轉(zhuan)(zhuan)臂4-8進(jin)行(xing)側向旋(xuan)(xuan)轉(zhuan)(zhuan)，當(dang)導向塊4-9與導向滑(hua)槽4-8-2接觸時(shi)，限定極限位置。當(dang)焊接結(jie)束后，通過旋(xuan)(xuan)轉(zhuan)(zhuan)氣缸II4-1帶(dai)動(dong)爪(zhua)型轉(zhuan)(zhuan)臂4-8旋(xuan)(xuan)轉(zhuan)(zhuan)離開圓管和鋼絲，在進(jin)行(xing)取件。實(shi)現裝夾和拆卸的自(zi)動(dong)化。

縱向旋轉導(dao)向夾緊機構5結構如(ru)圖7所示(shi)，用于在內部夾緊鋼絲(si)，并(bing)且為圓管提供側面(mian)支撐。
