Abstract

The invention belongs to the technical field of drill rod production, and relates to a three-edged drill rod machining method and automatic welding equipment thereof. According to the method, an inner connector and an outer connector are welded through forging forming and the automatic welding equipment, wherein the automatic welding equipment comprises a base, fixing sleeves, a floating welding device and a driving device; the fixing sleeves are arranged at the two ends of the base, the two fixing sleeves are rotationally connected with the base, and the fixing sleeves are connected with the driving device and driven by the driving device to rotate; a three-edged drill rod is fixedly clamped between the two fixing sleeves and rotates along with the fixing sleeves; and the floating welding device comprises a welding gun and a floating device, the welding gun is connected with the floating device and is arranged at a to-be-welded position of the three-edged drill rod, one end of the floating device is in sliding contact with the outer surface of the three-edged drill rod and floats up and down along with rotation of the three-edged drill rod, and the distance between the welding gun and the three-edged drill rod is kept unchanged. According to the three-edged drill rod machining method and the automatic welding equipment, floating positioning is carried out through the shape of the three-edged drill rod, positioning is more accurate, and the welding quality is improved.

Description

technical field [0001] The invention belongs to the technical field of drill pipe production, and relates to a processing method for a triangular drill pipe and automatic welding equipment thereof. Background technique [0002] The traditional triangular drill pipe consists of a triangular outer joint, a triangular steel pipe, and a triangular inner joint. The outer joint and inner joint of the triangular drill pipe are all processed by round steel, the machining allowance is large, the milling process is laborious and laborious, and wastes materials. After the triangular inner joint, triangular outer joint and triangular steel pipe are assembled, the tooling is positioned and spot welded first, and then manually welded in place by manual surfacing. The manual welding welding method has harsh environment and high labor intensity, and requires a high level of welding for the operator. Contents of the invention [0003] In view of this, the object of the present invention ...
