图1的填料盖、图2的法兰及弯管、三通、四通等零件,由于形状特殊,小批生产一般都用四爪卡盘来夹紧加工。这样装卡速度低,并且劳动强度大。现在我们用报废了的三爪卡盘,改制成双爪自定心卡盘,克服了以上缺点。改制的方法是:在旧三爪卡盘比较完好的原有槽对面刨一条形状相同的槽,在此两条槽中配上相应的卡爪,把另外二条槽用铁片堵住就可使用。图3是弯管装图1的填料盖、图2的法兰及弯管、三通、四通等零件,由于形状特殊,小批生产一般都用四爪卡盘来夹紧加工。这样装卡速度低,并且劳动强度大。现在我们用报废了的三爪卡盘,改制成双爪自定心卡盘,克服了以上缺点。改制的方法是:在旧三爪卡盘比较完好的原有槽对面刨一条形状相同的槽,在此两条槽中配上相应的卡爪,把另外二条槽用铁片堵住就可使用。图3是弯管装在改装好的双爪卡盘上的情况。
Figure 1, the filler cap, flange and bend in Figure 2, three links, Stone and other parts, due to the special shape, small batch production are generally claw chuck with four claw processing. This card loading speed is low, and labor-intensive. Now we use a scrapped three-jaw chuck, transformed into double-jaw self-centering chuck, to overcome the above shortcomings. The restructuring method is: In the old three-jaw chuck relatively intact original slot opposite a planing a groove, in the two slots with the corresponding claws, the other two slots with iron pieces can be used . Figure 3 is the elbow fitted with filler cover Figure 1, Figure 2 and the elbow pipe, tee, Stone and other parts, due to the special shape, small batch production are generally four claw chuck to clamp processing. This card loading speed is low, and labor-intensive. Now we use a scrapped three-jaw chuck, transformed into double-jaw self-centering chuck, to overcome the above shortcomings. The restructuring method is: In the old three-jaw chuck relatively intact original slot opposite a planing a groove, in the two slots with the corresponding claws, the other two slots with iron pieces can be used . Figure 3 is installed in the modified double-claw chuck on the situation.
