Problems solved by technology

The former has great advantages for welding small-size products, but the problems of moment of inertia and inter-mechanism synchronization caused by the rotation of large-size products with super large diameter and long length make the welding quality not well guaranteed. It is easy to be damaged; the latter is due to the movement of the gantry and the inability of the gantry foundation to sink, resulting in a higher working axis, which brings difficulties for workers to operate and poor operating safety. There is no good technical solution in the prior art to solve the problem. this problem

Abstract

The invention discloses a circular seam milling and friction stir welding integrated device for an aluminum alloy storage tank. The circular seam milling and friction stir welding integrated device comprises a friction stir welding machine head and a milling machine head and further comprises an annular gantry, a lathe bed, a headstock and a tailstock. The annular gantry is arranged in the middle of the lathe bed. Transmission sliding rails are arranged at the positions, on the two sides of the annular gantry, of the lathe bed. The headstock and the tailstock are installed on the transmission sliding rails on the two sides of the annular gantry correspondingly. A swing mechanism is arranged on the annular gantry, and the friction stir welding machine head and the milling machine head are installed on the swing mechanism. When the circular seam milling and friction stir welding integrated device is used for carrying out circular seam milling and friction stir welding on the aluminum alloy storage tank, a workpiece is mounted on the headstock and the annular gantry as well as the tailstock and the annular gantry, the workpiece does not need to rotate, the friction stir welding machine head and the milling machine head rotate around the workpiece through the swing mechanism to carry out milling machining or welding machining, the problem of device abrasion or precision reduction caused by large inertia brought by workpiece rotation is avoided, and the milling machining quality and the welding quality are guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to an integrated device for milling the circumferential seam of an aluminum alloy storage tank and friction stir welding. Background technique [0002] In recent years, with the development of aerospace technology, there is an urgent need for efficient and rapid manufacturing of large-size aluminum alloy cylinders. Compared with fusion welding, friction stir welding has higher welding strength, less welding deformation, and is greener. It can be applied to the manufacture of storage tanks. [0003] Friction stir welding has been hailed as the most creative invention in the welding field for 30 years. It is a high-quality, efficient, green, low-cost, and low-distortion solid-phase welding method that completely solves the problems caused by welding of various non-ferrous metals. A series of problems, and gradually replaced the fusion welding method, has been ...
