Problems solved by technology

[0003] Metal oil storage tanks are generally huge in size and are welded on-site by a large number of shells. In order to improve the strength of the tank, some shells need to be welded with inner ribs in advance. The inner ribs are arc-shaped, perpendicular to the shell and welded into one. The size of the workpiece is r

Abstract

The invention provides oil tank shell inner rib plate welding equipment and belongs to the field of automatic welding equipment. The welding equipment is composed of a longitudinal guide rail, a base, stand columns, a sliding plate, a cross beam, a telescopic arm and a welding mechanism. In the welding process, a touch type displacement sensor collects the relative distance between a welding gun and a shell and the distance between the welding gun and an inner rib plate in real time, a control system controls a transverse servo motor to drive the telescopic arm to move in the horizontal direction and controls a vertical servo motor to drive an installing plate to move in the vertical direction, the relative position between the welding gun and the shell and the relative position between the welding gun and the inner rib plate are kept unchanged, the welding track is not influenced by errors of a work-piece clamping position, automation of the process of welding the inner rib plate of the oil tank shell is achieved, and welding quality and welding efficiency are improved easily.

Description

technical field [0001] The invention relates to a welding equipment for ribs in an oil tank shell, in particular to automatic equipment that uses a contact displacement sensor, a servo motor and a ball screw to realize the welding process of a rib in a large oil tank shell, and belongs to the field of welding automation equipment . Background technique [0002] As the world's second largest energy consumer, stable and safe energy supply has an increasing impact on China's economy, among which oil plays a particularly prominent role. It is imperative to establish my country's strategic oil reserves to ensure energy security. Drawing on mature international experience and domestic actual conditions, the basic storage method for my country to establish strategic oil reserves is the storage method of large metal storage tanks. [0003] Metal oil storage tanks are generally huge in size and are welded on-site by a large number of shells. In order to improve the strength of the t...
