The invention belongs to the technical field of
petroleum drill bit manufacturing equipment, and relates to an intelligent
welding tool for blades of a
petroleum drill bit. Three claws enclasp a drillstock, the
drill stock rotates horizontally, the tip of the center of the drill stock is propped against a top plane, a V-shaped groove is welded by a
welding robot, a water hole rotates to a position at an angle of 45 degrees, a blade compressing
assembly is close to the drill stock, flat blades and spiral blades are placed, first rapid pincers, second rapid pincers and third rapid pincers are used for compressing the blades, the
welding robot carries out point welding, the first rapid pincers, the second rapid pincers and the third rapid pincers are pulled open, the blade compressing
assembly leaves away from the drill stock and a round cap, the blades upwards overturn at an angle of 90 degrees and then stop, the foregoing steps are repeated, thus, the four flat blades and the four spiral blades are uniformly arranged on the drill stock and the round cap by point welding, then full-length welding is carried out, and the
petroleum drill bit overturns upwards to be disassembled. The intelligent welding tool for the blades of the petroleum
drill bit is accurate in positioning, specifications and dimensions of welding seams are unified, weld defects are avoided, the working efficiency is high, the intelligent welding tool is simple to operate, the
training period is short, health hazards are small, and manpower costs are saved.
