Abstract

The invention discloses a numerical control stirring friction welding system, which comprises a numerical control stirring friction welder [1] provided with control software, wherein a main shaft of the numerical control stirring friction welder [1] is provided with a stirring head [5]; a welding fixture [2] is arranged on a rotating platform [3]; the shaft center of the welding fixture is the same as that of a central shaft [7] of the rotating platform [3]; and a welding structure member [4] is arranged on the welding fixture [2]. The invention also discloses a welding method for the system, which comprises the following steps: 1, the compiling of numerical control programs; 2, system debugging; 3, assembly; 4, system centration; 5, the set of welding parameters; and 6, system zero restoring. The numerical control stirring friction welding system solves the problems of the welding of space curve welding seams and plane two-dimensional welding seams, and has the advantages of high welding precision, simple and convenient operation, and the like.

Description

technical field [0001] The invention relates to friction stir welding technology, in particular to a system for realizing friction stir welding combined with numerical control technology and a welding method thereof. Background technique [0002] The development of friction stir welding technology has become an open technology and has been widely used at home and abroad. For example, Chinese patent 95192193.2 discloses a friction stir welding method, which uses a non-consumable friction head, including a concave The bottom of the joint, attached to a replaceable pin with a threaded surface, passes the plastic zone material along the connecting element behind the friction head so that the plastic zone material solidifies to form a dense weld. Chinese patent 200410064484.2 discloses a method of friction stir welding, which is a rotary tool for friction stir welding equipped with a set of mechanical equipment, two parts to be welded are fixed on the platform, and the rotary too...
