Abstract
The embodiment of the invention provides a friction stir welding device, comprising a supporting assembly that comprises a longitudinal beam; a forward mounting supporting plate and a reverse mounting supporting plate fixedly mounted on two side faces of the longitudinal beam respectively; and a longitudinal beam rotating device connected with the longitudinal beam, wherein the longitudinal beam rotating device can drive the longitudinal beam to rotate, so that the forward mounting supporting plate or the reverse mounting supporting plate faces upwards, wherein the forward mounting supporting plate is used for supporting the edges of the concave curved surfaces of two arc-shaped profiles to be welded, and the reverse mounting inner supporting plate is used for supporting the edges of the convex curved surfaces of the arc-shaped profiles to be welded. The friction stir welding device solves the technical problem that in the prior art, in order to achieve friction stir welding of the arc-shaped profiles, two sets of special friction stir welding devices are needed.
Description
technical field [0001] The present application relates to the technical field of friction stir welding, and in particular, relates to a friction stir welding device. Background technique [0002] Welding is an important processing method in the manufacturing process of complex structures, and it is the most widely used and most efficient structural connection technology in the manufacturing process of metal structural parts. With the development requirements of modern lightweight and high-reliability structures, aluminum alloys are more and more used in engineering structure industries such as railways, automobiles, and aerospace due to their light specific gravity and excellent processing performance. Large coefficient, large shrinkage rate during solidification, uneven force and local plastic deformation during welding, resulting in large deformation after welding, affecting the dimensional accuracy of structural parts and product quality. The research and application of ...
