Abstract

The invention relates to a multifunctional composite movable gantry friction stir welding device, and belongs to the technical field of machine tool equipment. The multifunctional composite movable gantry friction stir welding device comprises a machine head, wherein a friction stir welding tool is arranged on the machine head; a follow-up welding pressing system and a weld joint flash milling system are further arranged on the machine head; the follow-up welding pressing system comprises a first follow-up compression roller device positioned in front of the friction stir welding tool and a second follow-up compression roller device positioned behind the friction stir welding tool; and the weld joint flash milling system comprises a milling cutter positioned behind the second follow-up compression roller device and a milling driving device connected with the milling cutter. The multifunctional composite movable gantry friction stir welding device realizes online flattening, polishing and grinding of workpieces before and after welding, and improves the welding quality and the welding production efficiency.

Description

technical field [0001] The invention belongs to the technical field of machine tool equipment, and relates to a multifunctional compound moving gantry friction stir welding equipment. Background technique [0002] The friction stir welding process is the most eye-catching welding method since the advent of laser welding. Its appearance will lead to major changes in the connection technology of non-ferrous metals such as aluminum alloys. Welding aluminum alloys with friction stir welding has achieved good results. At present, friction stir welding has reached a large-scale and industrialized application level in many fields such as shipbuilding, rail vehicles, aerospace manufacturing, automobile industry, and aviation industry. Correspondingly, higher requirements are put forward for friction stir welding equipment. The dynamic gantry friction stir equipment with high welding speed, large stroke and multi-dimensional curved surface welding came into being. [0003] Howeve...
