Abstract
The utility model discloses a zero-angle stirring and abrading welding joint. The zero-angle stirring and abrading welding joint is characterized by comprising a body; the body is provided with a cutter handle, a shaft shoulder and a stirring needle; the cutter handle is provided with an annular groove; the shaft shoulder is provided with an inner concave cavity which is internally provided with a convex rib; the stirring needle is of a conical table shape and is provided with a thread. The zero-angle stirring and abrading welding joint provided by the utility model has the beneficial effects that compared with a common stirring and abrading welding joint, the shaft shoulder of the welding joint provided by the utility model is not a plane any more, but a concave surface, can guarantee that a welding material can fill a welding clearance fully after zero-angle stirring and abrading welding, and can prevent defects of the welding clearance.
Description
Technical field
The utility model relates to a kind of plumb joint, be specifically related to a kind of plumb joint of zero degree agitating friction.
Background technology
Existing friction stir welding is only applicable to common agitating friction welding, because the welding of common agitating friction can make plumb joint insert in welding material in the mode of a small angle inclination, after this mode can guarantee welding, material can fill up welding gap.But weld for zero degree agitating friction, this plumb joint is just inadaptable, insert, and the shaft shoulder of stirring-head is a plane because stirring-head is perpendicular to solder side, after friction, welding material can, toward surrounding splatter, cause welding rear material and can not fill up welding gap and produce weld defect.
Utility model content
For the deficiency existing in prior art, the utility model object is the plumb joint that is to provide a kind of zero degree agitating friction.
To achieve these goals, the utility model is to realize by the following technical solutions: a kind of plumb joint of zero degree agitating friction, it is characterized in that: comprise body, described body is provided with handle of a knife, the shaft shoulder and mixing needle, described handle of a knife is provided with annular groove, and the described shaft shoulder is provided with inner cavity, in described inner cavity, is provided with convex tendon, described mixing needle is taper type, and mixing needle is provided with screw thread.
The low 0.1mm of aspect ratio shaft shoulder outer end face of described convex tendon, convex tendon surrounding is inner cavity, when carrying out agitating friction welding, the mixing needle of rotation inserts in weldment completely, shaft shoulder outer and weldment upper surface rub, and the material of a part of solid solution condition is squeezed in inner cavity, and the convex tendon of inner cavity is proceeded friction with the material of clamp-oning, the mobility that keeps material, so that weld seam is filled up in follow-up inflow bottom.
The screw thread of described mixing needle, contributes to mixing needle material around along with lines upwards flows into the inner cavity place of the shaft shoulder, flows into afterwards the weld seam that need fill up again.
Annular groove on described handle of a knife, the contact area of increase handle of a knife and air, improves heat-sinking capability, reduces the temperature of plumb joint, improves the life-span of plumb joint.
The beneficial effects of the utility model: compare with common friction stir welding, the application's the plumb joint shaft shoulder is no longer a plane, but a concave surface can guarantee that the rear welding material of zero degree agitating friction welding can fill up welding gap, avoids the defect of weld seam.
