Welding bracket for rotating shaft of horizontal tail of airplane

Abstract

The invention provides a welding bracket for a rotating shaft of a horizontal tail of an airplane. The welding bracket comprises a supporting base, supporting rods, sliding sleeves, force bearing rods, wheels, a screw rod, a rocker arm and a braking system. The welding bracket is characterized in that the two supporting rods are welded to the two sides of the supporting base; the sliding sleeves are fixed to the lower ends of the force bearing rods; the sliding sleeves can move left and right on the supporting rods; the force bearing rods are connected with the wheels; every two force bearing rods are fixed together to form a set of supporting rolling system with the corresponding two wheels; the screw rod is installed between the two sets of supporting rolling systems; the rocker arm is installed at one end of the screw rod; the braking system is installed below the corresponding wheel; and the braking system is fixed to the corresponding force bearing rod. When the welding bracket is used for welding, the rotating shaft of the horizontal tail is rotated by hands at a constant speed so that overturning of the rotating shaft of the horizontal tail of the airplane can be achieved, operation is convenient, the welding efficiency is high, and the qualification rate can reach 98% through inspection.

Description

Technical field [0001] The invention relates to a technological equipment for welding production, in particular to an equipment for circular weld welding. Background technique [0002] At present, the circular welds of the flat tail shaft shoulders of aircraft are often produced by manual arc welding, which requires very high skills for the welding operator. After each section of the circular weld, the welding operator has to stop and flip the parts. During the welding process, more The welding operation is difficult, and the welding operation is very inconvenient. The main disadvantages are: poor welding forming, low production efficiency and difficult to guarantee welding quality. Summary of the invention [0003] In order to improve the welding production efficiency of the circular welding seam of the shaft shoulder of the plane tail shaft, reduce the difficulty of the welder's operation, and ensure the beautiful appearance of the weld seam and the welding quality, the present...

Problems solved by technology

[0002] At present, the annular weld of the shaft shoulder of the aircraft's horizontal tail shaft is often produced by manual arc welding, which requires high skills for the welding operator. After welding a section of the annular weld, the welding operator has to stop and turn the part. During the welding process, increased The welding operation is difficult, and the welding operation is very inconvenient

Its main disadvantages are: poor welding formation, low production efficiency and difficult to guarantee welding quality
