Embodiment 1
[0049] like Figure 1-3As shown, this embodiment provides a friction stir welding device, which includes a shaft shoulder assembly structure and a waste collector 3 . Wherein, the shaft shoulder combination structure includes a stationary shaft shoulder 2 and a stirring needle (not shown) arranged coaxially with the stationary shaft shoulder, and a plurality of circular discharge holes 2-1 are provided on the side wall of the lower end of the stationary shaft shoulder; The cutting tool 1 has a rotating housing 1-1 that can be driven independently by a motor, and has a cavity therein for accommodating a stationary shaft shoulder 2, wherein the rotating housing 1-1 can be connected to the rotating housing 1-1 through a bearing. The stationary shaft shoulder 2 is installed coaxially; the bottom of the rotating casing 1-1 has an opening, which is communicated with the cavity structure and is suitable for guiding the stationary shaft shoulder 2 to protrude from the cavity; several ...
Embodiment 2
[0057] like Figure 4-6 As shown, this embodiment provides a friction stir welding device, which is different from the friction stir welding device shown in Embodiment 1 in that the discharge hole 2-1 of the stationary shaft shoulder is a groove-shaped structure. like Figure 4 and 5 As shown, two discharge holes 2-1 with elongated groove-shaped structures are provided on the side wall of the lower end of the stationary shaft shoulder, and correspondingly, two cutting blades 1-3 are also provided.
Embodiment 3
[0059] This embodiment provides a friction stir welding system, which includes a friction stir welding tool, the friction stir welding tool has a stationary shaft shoulder and a stirring needle, and a number of discharge holes are provided on the side wall of the lower end of the stationary shaft shoulder; The casing is driven by a motor, and the rotating casing has a cavity inside, and the cavity is used for accommodating the stationary shaft shoulder; the bottom of the rotating casing has an opening, which is communicated with the cavity structure and is suitable for In order to guide the extension of the stationary shaft shoulder from the cavity; the bottom of the rotating casing is provided with a plurality of cutting blades, which are arranged at intervals around the opening and extend along the extension direction of the stationary shaft shoulder; the cutting blades can be combined with Fitting of static shoulder for the removal of waste outside the static shoulder;
