Automatic team assembling and automatic spot-welding device for circular seams of shell rings of pressure containers

Abstract

The invention discloses an automatic team assembling and automatic spot-welding device for circular seams of shell rings of pressure containers. The automatic team assembling and automatic spot-welding device comprises a horizontal sliding table base, a shell ring supporting base and a shell ring conveying mechanism; a horizontal sliding table is arranged on the horizontal sliding table base; a lifting sliding table stand column is installed at the front end of the horizontal sliding table; an umbrella-rib-shaped inner supporting mechanism is installed on the lifting sliding table on the lifting sliding table stand column; the shell ring supporting mechanism is arranged on the shell ring supporting base; a length-adjustable baffle is installed at the front end of the lifting sliding table; a shell ring pushing mechanism is installed on the shell ring supporting base; a hydraulic cylinder and a rotary driving mechanism are further installed on the lifting sliding table; the hydraulic cylinder drives the umbrella-rib-shaped inner supporting mechanism to open, and the rotary driving mechanism drives the umbrella-rib-shaped inner supporting mechanism to rotate to drive the circular seams of the shell rings to rotate and shift; and a robot automatic spot-welding system is mounted on one side of the shell ring supporting base. The device disclosed by the invention can be used for automatically team assembling and spot-welding the shell rings, and the whole working process is automatically completed by adopting intelligent control, so that the manufacturing efficiency is improved and the manufacturing cost is saved.

Description

technical field [0001] The invention belongs to the technical field of pressure vessel manufacture and welding, and in particular relates to an automatic team assembly and automatic spot welding equipment for pressure vessel cylinder joint girth seams. Background technique [0002] For thin-walled cylindrical joints of pressure vessels, especially stainless steel cylindrical joints, the circular seam is usually welded by plasma welding technology or deep penetration TIG (or K-TIG) welding technology, and the weld seam with a wall thickness below 8mm may not be opened. Groove welding realizes single-sided welding and double-sided forming. This advanced and efficient welding method has high requirements for the assembly gap and misalignment of the circular seam, which cannot exceed 10% of the plate thickness, that is to say, for a plate thickness of 8mm The assembly gap and misalignment of the circular seam should be less than 0.8mm. The assembly quality of the circular seam w...
