Radial feeding device of welding head of taper welding machine

Abstract

The invention provides a radial feeding device if a welding head of a taper welding machine and relates to a special welding machine used for welding tapered workpieces. The radial feeding device is arranged on the welding position of the taper welding machine to connect a welding head and a machine frame movably and comprises a main rotary disk movably connected to the machine frame, a rib-shifting mechanism and a radial feeding mechanism capable of guiding the ribs shifted by the rib-shifting mechanism to the welding position in a continuously rotating process of the main rotary disk, wherein the rib-shifting mechanism and the radial feeding mechanism are fixedly connected to the main rotary disk; the welding head is connected to the radial feeding mechanism; and the rib outlet of the rib-shifting mechanism corresponds to the welding head. The radial feeding device realizes the continuous axial motion of the workpieces, the continuous rotation of the main rotary disk and the periodical radial motion of the radial feeding device so as to keep longitudinal ribs and transverse ribs and the welding head reliably contacted to ensure the automatic welding of the tapered workpieces. The radial feeding device has the advantages of high automation, good reliability and skillful structure.

Description

technical field [0001] The invention relates to a special welding machine for welding tapered workpieces, in particular to a radial feed device of a welding head on the tapered welding machine. Background technique [0002] At present, the reinforced cages of conical electric poles are bound manually, which is very inefficient, and the strength and quality of the manually welded reinforced cages are low through binding means. If it is necessary to realize the mechanized welding process between the longitudinal reinforcement and the ring reinforcement on the steel bar skeleton cage of this conical pole, there is a difficult problem, that is, how to maintain contact between the welding head and the welding point on the tapered surface of the workpiece as the taper changes. It is necessary to move the welding head and the workpiece in the radial direction while moving axially with each other; or the welding head is fixed, and the contact point caused by the taper does not match...
