Embodiment 1

[0042] like Figure 1-8 As shown, the present embodiment provides a snap-fit ​​welding tool, which includes a stationary shaft shoulder 1, the top end of the stationary shaft shoulder has a positioning ring 12, and the bottom end has a welding surface 15; There are at least two bending slots 11, such as Figure 5As shown, the number of the bending slots 11 is four, and they are evenly arranged around the positioning ring 12; wherein, preferably, the bending slots include a vertically arranged first slot and an obliquely arranged second slot. The first slot and the second slot are communicated; the above-mentioned welding tool also includes a shoulder flange 3 and a stirring needle 2 arranged coaxially with the stationary shaft shoulder 1, and the bottom end of the shoulder flange 3 has an accommodating The positioning hole 32 of the positioning ring 12 has a clamping member in the positioning hole 32 that is adapted to the bending and clamping groove 11 . The snap-on assembl...

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-on assembly welding tool described in Embodiment 1. It adopts the snap-type structure to realize the clamping and dismounting of the stationary shaft shoulder. There is no need to install and remove the nut when assembling the axle shoulder, and the efficiency is high; Coaxial connection of shoulder flanges.

Abstract

The invention relates to the technical field of friction stir welding, in particular to a snap-on assembling welding tool and an assembling method. The snap-fit ​​welding tool has a positioning ring at the top of the stationary shoulder, and at least two bending slots are arranged on the positioning ring; the bottom end of the shoulder flange has a positioning hole for accommodating the positioning ring , wherein, in the positioning hole, there is a clamping piece adapted to the bending slot; through the snap fit of the clamping piece of the shoulder flange and the bending slot of the stationary shoulder, Shaft-shoulder connection can be achieved through simple corner action, and disassembly is efficient; the snap-on assembly welding tool provided by the present invention adopts snap-on structure to ensure that the two structures are concentric, so that the stationary shaft shoulder and the shaft shoulder can be realized. Coaxial connection of flanges.

Description

technical field [0001] The invention relates to the technical field of friction stir welding, in particular to a snap-on assembling welding tool and an assembling 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 needle of traditional friction stir welding tools are integrated, while the shoulder and stirring needle of static shoulder welding tools are separate. During the welding process, the stirring needle is in a rotating state, but the shaft shoulder does not rotate, which requires fixing the stirring needle on the rotating shaft of the main shaft of the welding equipment and the shoulder on the fixing surface of the welding equipment respectively. [0003] For the installation method of the stationary shaft shoulder, Chinese patent CN201420240365.7 discloses a static shaft shoulder welding devi...
