AI Technical Summary
In the prior art, rotary tools used for friction stirring are complex in structure and expensive when load control is required, making them difficult to apply in machining centers that can only perform position control.
A rotary tool was designed, comprising a main body, a stirring pin, a shoulder, and an elastic component. Load control is achieved through the action of the elastic component, the main body transmits rotational force, and the stirring pin and shoulder perform friction stirring and pressing, respectively. Precise insertion is achieved in conjunction with a position control component.
Load control was achieved in the machining center, ensuring accurate insertion depth and position of the stirring pin and the shaft shoulder, improving the joint quality and reducing burr generation.
