An automobile fuel tank processing device and method

Abstract

This invention discloses a processing apparatus and method for automotive fuel tanks, belonging to the field of irregularly shaped welded component processing technology, to solve the technical problems of low processing efficiency and high quality risk in existing automotive fuel tank processing. In this apparatus, a first support body is suspended at one end of a mounting body, and a second support body is suspended at the other end of the mounting body. A first protrusion is suspended on the side of the first support body facing the second support body, and a second protrusion is suspended on the side of the second support body facing the first support body. The first and second protrusions are respectively inserted into through holes on the front and rear ends of the fuel tank shell, allowing the fuel tank shell to be suspended above the mounting body. In this method, the horizontal center line of the fuel tank shell is initially determined by using conformal tooling and reference scribing, and the accuracy of the horizontal center line is judged; the accuracy of the horizontal center line is then verified again through trial processing. This invention can be used for the processing of automotive fuel tanks.
