Abstract

The invention relates to a strong-deformation-interface type friction stir welding soldering tool. With the tool, problems that a hook-shaped defect exists in a welding joint, weak connection occurs, and the stirring head is worn seriously according to the existing friction stir welding in overlap joint with dissimilar materials can be solved. A stirring pin mounting hole is formed in axes of an adapter sleeve and a clamping handle; a stirring pin is arranged at the top of the stirring pin mounting hole; and an adjusting bolt is arranged at the lower part of the stirring pin mounting hole. The part, exposed out of the upper end surface of the adapter sleeve, of the stirring pin is a tapered threaded surface; a concave end surface is arranged at the upper end surface of the stirring pin; three concave arcs are arranged at the concave end surface along the peripheral surface and are distributed on the concave end surface uniformly; and rigid salient points are arranged on the concave end surface. A milling unit is arranged at a lower end cylinder of the stirring; and a transition zone is formed between the stirring pin body part and the milling unit. A concave shaft shoulder is arranged at the upper end surface of the adapter sleeve; the stirring pin mounting hole is formed in the center of the adapter sleeve, wherein the diameter of the stirring pin mounting hole is identical with that of the stirring pin. The tool is used for welding of aluminium / steel dissimilar materials.

Description

technical field [0001] The invention relates to a friction stir welding tool, in particular to a friction stir welding tool with strong interface deformation and adjustable depth of exploration. Background technique [0002] Aluminum / steel dissimilar materials as body materials can reduce the weight of the car, realize the light weight and high strength of the body frame structure, improve the dynamic performance and economy of the body, improve fuel economy, reduce environmental pollution, and achieve the purpose of energy saving and emission reduction. At the same time, it also ensures the safety during driving, and its reliable connection is the key to solving the application of aluminum alloy in automobile body materials. However, the physical parameters, lattice parameters, and structure of aluminum / steel are very different, which makes the connection of aluminum / steel dissimilar metals more difficult, and brittle and hard metals are easily formed at the connection inte...
