The invention discloses a gravity self-feed
welding feeding mechanism, and belongs to the field of machines. The gravity self-feed
welding feeding mechanism comprises an upper rack, a lower rack, telescopic shafts, springs, shafts, a driving wheel, a driven wheel, anti-slipping teeth, nuts, a rotating shaft, a
pulley, a friction wheel, a
rope and a weight. The upper rack and the lower rack are provided with rectangular grooves respectively, through holes are formed in each rectangular groove, the telescopic shafts penetrate through the through holes of the rectangular groove in the upper rack or the rectangular groove in the lower rack, one ends of the telescopic shafts are connected with the driven wheel, the other ends of the telescopic shafts are matched with the nuts, the two ends of the rotating shaft are provided with the driving wheel and the
pulley respectively, the rotating shaft is assembled on the upper rack or the lower rack, the
rope is wound in a groove in the outer edge of the
pulley, and the weight is connected with the
tail end of the
rope. The problem that a
copper material is fed unevenly in the existing
copper brazing process of a wear plate and a
cutting ring is solved, and the gravity self-feed
welding feeding mechanism has the advantages of being simple in structure, reasonable in design and easy to manufacture.
