Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
It is front and rear described in this example, when being used using stirring-head towards workpiece a side as front, after the side away from workpiece is
Side.
Embodiment
As shown in Figures 2 to 7, a kind of stirring header structure for agitating friction weldering, including be connected and coaxial stirring
Pin 22 and shaft shoulder body 21, mixing needle 22 protrude from 21 front end face of shaft shoulder body, and the rear portion of shaft shoulder body 21 is integrally formed with clamping part
21a, for being connected with handle of a knife.To improve the intensity of stirring-head 2 in this example, mixing needle 22 and shaft shoulder body 21 are integrally formed.
Stirring-head 2 is made of shaft shoulder body 21 and 22 two parts of mixing needle, and stirring-head 2 is by 21 rear portion of shaft shoulder body and handle of a knife 1
It is directly connected to, the larger transition portion of the volume that disappeared and coupling part, 2 overall dimensions of stirring-head significantly reduce, relative to tradition
Stirring-head 2, greatly reduce cost, saved resource.
Wherein, 21 front end face of shaft shoulder body is along the circumferential direction provided with groove 21b, to increase shaft shoulder body during agitating friction weldering
21 and hold together aggregate capabilities by the friction between weldering mother metal and to the bag of plastic metal material, improve welding effect.
In order to reduce the heat accumulation in 2 welding process of stirring-head, the service life of stirring-head 2 is improved, before shaft shoulder body 21
Thread groove 21c is along the circumferential direction provided with portion's outer wall.
In this example, the tapered structure of 22 main body of mixing needle, outer wall is provided with the raised 22a of spiral distribution, and is provided with
Three scarf 22b, without raised 22a, the front end face B of mixing needle 22 is sphere for scarf 22b positions.Mixing needle 22 is with protrusion
22a and scarf 22b, to increase during agitating friction weldering mixing needle 22 and by the friction between weldering mother metal, improve welding effect
Fruit.
Preferably, the diameter of clamping part 21a is less than the anterior diameter of shaft shoulder body 21, as shown in Figure 6；Or shaft shoulder body 21 is each
Section diameter is equal, as shown in Figure 2.
As shown in Figure 4 and shown in Fig. 7, the one or both sides milling of clamping part is flat, stop surface is formed, in order to consolidate with handle of a knife
Fixed, both relatively rotate for limitation, and corresponding clamping screw 3 is one or two, and stop surface is by removing clamping part 21a outer wall materials
