Intelligent welding tool for blades of petroleum drill bit

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of oil drill bit manufacturing equipment, and relates to an intelligent welding tool for blades of an oil drill bit. Background technique [0002] The oil drill bit is an important tool for oil drilling and an important component used to drill oil during oil extraction. Its working performance will directly affect the drilling quality, drilling efficiency and drilling cost. [0003] The oil drill bit is butt welded by a drill shank, four flat blades, four helical blades and a round cap. The drill shank is hollow tubular, and the outer circular surface of one end has a drill shank bevel surface, and the inner circular surface has a slit inner circular surface on the corrugated surface. The round cap is a body of revolution, the size in the diameter direction is larger, and the size in the direction of the center of rotation is smaller. One end of the center line is the outer conical surface of the round cap,...
