Abstract

The invention provides a servo driven girth welding internal supporting device for a storage tank and relates to the technical field of girth welding. The internal supporting device comprises a mounting body, a sliding table, a connecting rod, a driving ring and a servo electric cylinder. A linear guide rail is radially arranged on the mounting body, the sliding table is slidably connected to thelinear guide rail, a supporting block is arranged at the outer end of the sliding table, the inner end of the sliding table is hinged to the driving ring through the connecting rod, the driving ring is rotatably connected to the mounting body, and one end of the servo electric cylinder is hinged to the mounting body while the other end is hinged to the driving ring. In a process of positioning thebottom of the storage tank, the servo electric cylinder is started to drive the driving ring to rotate relative to the mounting body, the sliding table is pushed by the connecting rod to slide outward along the linear guide rail till the supporting block is attached to the bottom of the storage tank seamlessly to position and fix the bottom of the storage tank. Even if a certain manufacturing error occurs at the bottom of the storage tank, it can be further ensured that the internal supporting device is attached to the bottom of the storage tank seamlessly, so that the splicing and welding precision and quality of the bottom of the storage tank are improved effectively.

Description

technical field [0001] The invention relates to the technical field of girth welding, in particular to a servo-driven internal support device for girth welding of a storage tank. Background technique [0002] In the past few decades, the welding of the girth seam of the tank bottom in my country has experienced the gradual development process of manual welding, semi-automatic welding and automatic welding. However, as the demand for weight reduction of the storage tank increases, the wall thickness of the tank bottom is thin and the rigidity is weak, so the requirements for the quality of the tailor welding of the tank bottom are also getting higher and higher. [0003] At present, the internal support structure of the rod system is often used to fix and position the workpiece. The size of the external diameter of the internal support structure of the rod system cannot be changed after turning, and it has a good positioning effect on the workpiece of the rated size.
