Embodiment 1

[0042] Such as Figure 1-8 As shown, this embodiment provides a buckle-type assembly welding tool, which includes a stationary shoulder 1, a positioning ring 12 is provided at the top of the stationary shoulder, and a welding surface 15 is provided at the bottom end of the stationary shoulder; There are at least two bending slots 11, such as Figure 5As shown, the number of bending slots 11 is set to four, which are evenly arranged around the positioning ring 12; wherein, preferably, the bending slots include a first slot vertically arranged and a second slot arranged obliquely Groove, the first slot communicates with the second slot; the above-mentioned welding tool also includes a shoulder flange 3 and a stirring pin 2 coaxially arranged with the stationary shoulder 1, and the bottom end of the shoulder flange 3 has a The positioning hole 32 of the positioning ring 12 has a clamping member adapted to the bending slot 11 in the positioning hole 32 . The snap-fit ​​assembly ...

Embodiment 2

[0058] This embodiment provides a friction stir welding device, which includes a motor, a rotating spindle, and a welding tool, and the welding tool is the snap-fit ​​assembly welding tool described in Embodiment 1. It adopts the snap-in structure to realize the clamping and dismounting of the static shoulder, and there is no need to install and disassemble the nut when assembling the shoulder, which has high efficiency; moreover, when the snap-in structure is used to ensure that the two structures are concentric, the static shoulder and the shaft can be realized. Coaxial connection of shoulder flanges.

Abstract

The invention relates to the technical field of friction stir welding, in particular to a buckle type assembly welding tool and an assembly method, wherein according to the buckle type assembly welding tool, a positioning ring is arranged at the top end of a static shaft shoulder; at least two bent clamping grooves are formed in the positioning ring; a positioning hole for accommodating the positioning ring is formed in the bottom end of a shaft shoulder flange, wherein a clamping part matched with the bent clamping grooves is arranged in the positioning hole; through the buckling type matching of the clamping part the shaft shoulder flange and the bent clamping grooves of the static shaft shoulder, connection of the shaft shoulder can be achieved through simple and convenient corner turning action, and high-efficiency disassembly is realized. According to the buckle type assembly welding tool provided by the invention, when a buckle type structure is used in manufacturing, the two structures are ensured to be concentric to realize coaxial connection of the static shaft shoulder and the shaft shoulder flange.

Description

technical field [0001] The invention relates to the technical field of friction stir welding, in particular to a buckle-type assembly welding tool and an assembly method. Background technique [0002] Static shoulder friction stir welding (SSFSW) is a new type of friction stir welding (FSW) technology developed on the basis of traditional friction stir welding. The shoulder and stirring pin of the traditional friction stir welding tool are integrated, while the shoulder and stirring pin of the static shoulder welding tool are split. During the welding process, the stirring pin is in a rotating state, but the shaft shoulder does not rotate, which requires fixing the stirring pin on the rotating shaft of the main shaft of the welding equipment, and fixing the shaft shoulder on the fixed surface of the welding equipment. [0003] As for the installation method of the static shoulder, Chinese patent CN201420240365.7 discloses a static shoulder welding device of friction stir we...
