Automatic steel cylinder girth welding device

Abstract

The invention relates to the technical field of steel cylinder girth welding, and specifically relates to an automatic steel cylinder girth welding device. The automatic steel cylinder girth welding device comprises an operation table, wherein an opposite driving assembly is arranged at the bottom of the operation table; the opposite driving assembly comprises two movable bottom plates; a movablenotch used for allowing each movable bottom plate to move is formed in the operation table; a rotary table is arranged at the top of each movable bottom plate; a left side rotating assembly and a right side auxiliary rotating assembly are arranged on the two rotary tables correspondingly; clamping jaw assemblies are arranged at the adjacent ends of the left side positioning rotating assembly and the right side rotating assembly correspondingly; lifting adjusting assemblies are arranged above the left side rotating assembly and the right side auxiliary rotating assembly correspondingly; a vertical support is arranged between the two clamping jaw assemblies; and a welding gun capable of lifting is arranged on the vertical support. According to the device, the height of each steel cylinder needing to be welded can be adjusted correspondingly, butt joint is automatically carried out, the height of the welding gun can be automatically adjusted, and the welding precision is improved.

Description

Technical field [0001] The invention relates to the technical field of steel cylinder circumferential seam welding, in particular to an automatic steel cylinder circumferential seam welding device. Background technique [0002] At present, the Chinese patent document with the authorized announcement number CN201900395U in the prior art discloses a liquefied petroleum gas cylinder circumferential seam welding device, including a bracket and a steel cylinder circumferential seam welding device arranged on the bracket. The steel cylinder circumferential seam welding device Including bottom welding torch and cover welding torch. The bracket is also provided with a steel cylinder clamping device, which is hinged to the bracket and connected with the rotating shaft through a key. When the rotating shaft rotates, the steel cylinder clamping device is driven to rotate. The steel cylinder clamping device is two installed on both sides of the steel cylinder. Clamps, the two clamps squeeze...

AI Technical Summary

Problems solved by technology

There is also a steel cylinder clamping device on the bracket, which is hinged with the bracket and connected with the rotating shaft through a key. When the rotating shaft rotates, it drives the steel cylinder clamping device to rotate. The steel cylinder clamping devices are two Two clamps press the steel cylinder towards the middle to clamp and fix the steel cylinder. After the steel cylinder clamping device clamps the steel cylinder, it is driven by the rotating shaft and rotates on the bracket, while the welding torch does not move, so as to realize the welding of the steel cylinder. In existing technologies, the height of each steel cylinder to be welded cannot be automatically adjusted, so it is inevitable that the two steel cylinders will be offset when they are docked, which will affect the quality of the steel cylinder after welding, and the welding torch is fixed and cannot be adjusted when welding. The welding height of the welding torch, therefore, we propose an automatic steel cylinder girth welding device in order to solve the problems raised above
