Abstract

The invention relates to a device and method for enhancing rigidity, in particular to a device and method for enhancing the rigidity of a moving axis shoulder length stirring head. The device comprises reinforcing ribs, the stirring head and a supporting sleeve, wherein the supporting sleeve sleeves the stirring head, one end of each reinforcing rib is fixedly connected to the supporting sleeve, and the other end of each reinforcing rib is fixedly connected to a main shaft cover of the stirring head. The deformation of the stirring head in the welding process can be limited in the welding process of the supporting sleeve, the service life of the stirring head is prolonged, and the weld joint quality is improved; the copper supporting sleeve makes contact with the steel stirring head, the main wear is concentrated on the soft supporting sleeve, the friction damage to the stirring head is low, and copper is high in heat conductivity and makes cooling easy; the supporting sleeve is internally provided with graphite, the graphite is high lubricity and high in melting point, and the friction wear between the supporting sleeve and the stirring head in the welding process is reduced.

Description

technical field [0001] The invention relates to a device and method for enhancing rigidity, more specifically, a device and method for enhancing the rigidity of a stirring head with a long shoulder of a moving shaft. Background technique [0002] The weldability of friction stir welding is average, and some welds are close to the surrounding convex parts. The ordinary stirring head cannot weld them effectively, and the stirring head needs to be lengthened to reduce the welding process equipment and parts. interference to improve the accessibility of friction stir welding. However, during the friction stir welding process, the shaft shoulder of the stirring head and the stirring needle suffer from relatively large forward resistance. When the stirring head is longer, the distance between the shoulder and the clamping part of the stirring head is relatively large, so A large bending moment will be generated, which will cause a certain deformation of the stirring head. This b...
