如图所示,用一根152.4mm 长,边长为25。4mm的等边角铁,在中间开 25.4一焊接用开口,即是一种高效焊接钻头和铰刀延长部分的简易夹具。被焊接的钻头延长部分的直径应稍微小一点,为使不同直径的两部分对中,需在直径较小的延长部分垫上厚度为两直径之差的一半垫片。另外,还需将角铁的边角切成斜口,以便于标准C形夹钳夹持。 As shown, a 152.4 mm long, 25.4 mm edged iron with a 25.4-inch opening in the middle provides a simple fixture for efficient welding of drill bits and reamer extensions. The diameter of the extended drill bit to be welded should be a little smaller. To center the two parts of different diameters, half the pads of the difference between the two diameters should be padded on the smaller diameter extension. In addition, the corners of the angle iron need to be beveled so that the standard C-clamp holds.
