Description
Technical field
The present invention relates to a kind of aluminium alloy fastening means, especially a kind of stirrer used for friction stir welding of aluminum alloy, tool
Say to body be a kind of no key hole Friction Stir Welding stirring-head.
Background technique
During carrying out Aluminum Alloy Friction Stir Welding, due to often there is the key hole for the end welded, significantly
The application of the welded blank in this region is affected, especially welds the plate of circumferential series, this key hole defect effect is more
Greatly, can not carry out using.In order to overcome this difficulty, present aspect has manufactured and designed a stirring-head, easy to accomplish can stir
Friction welding end is without key hole.Its is easy to operate, and expense is low, is easy to promote and apply.
Summary of the invention
The purpose of the present invention is be also easy to produce key when carrying out Aluminum Alloy Friction Stir Welding connection for existing stirring-head
The problem of keyhole, designs a kind of Friction Stir Welding stirring-head of no key hole.
The technical scheme is that
A kind of Friction Stir Welding stirring-head of no key hole, it includes shaft shoulder main body cylinder 1, mixing needle 3, controller 5 and adds
Heated filament 6, it is characterized in that the lower end of the shaft shoulder main body cylinder 1 is provided with cavity 2, one end of mixing needle 3 is located in the cavity 2
And income cavity can be moved up and down in the cavities under the control of telescoping mechanism 7 or is stretched out outside cavity, the shaft shoulder main body cylinder 1
Swollen straight long chamber 4 is opened with the center of mixing needle 3.Into being equipped with heater strip 6 in the bottom of long chamber 4, mixing needle 3, heater strip 6 and driving
The telescoping mechanism that mixing needle moves up and down is controlled by controller 5.
The heater strip 6 is connect by conducting wire I 8 with controller 5.
The telescoping mechanism is connect by conducting wire II 9 with controller 5.
The telescoping mechanism is bull electric pushrod.
The telescoping mechanism is electrostrictive mechanism.
The telescoping mechanism is hydraulic or pneumatic mechanism.
Beneficial effects of the present invention:
The present invention can be achieved weld without key hole defect to aluminum alloy plate materials, ensure that welding quality significantly, weld end
Performance is improved, at low cost, easy to make, is convenient for wide popularization and application.
Essence of the invention is exactly to squeeze semi-molten state by stirring-head and the high pressure effect of contraction in the end of welding
Aluminium alloy bar fill to form cavity fill solder and extruding, it is final to realize the weld seam without key hole.Stirring-head manufacture letter
Single, expense is low, is easy to promote and apply.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of Friction Stir Welding stirring-head of no key hole, it includes shaft shoulder main body cylinder 1, mixing needle 3, controller 5
With heater strip 6, controller 5 is conventional electrical control device, self design or can be subject to reference to pertinent texts and handbook
It realizes, the lower end of the shaft shoulder main body cylinder 1 is provided with cavity 2, and one end of mixing needle 3 is located in the cavity 2 and can stretch
Income cavity is moved up and down under the control of contracting mechanism 7 in cavity 5 or is stretched out outside cavity, in order to guarantee stirring-head and shaft shoulder main body
Cylinder 1 rotates synchronously, and cavity 5 and stirring-head 3 should design corresponding anti-rotation structure, and dual-cavity and biconvex can be used in anti-rotation structure
Swollen straight long chamber 4 is opened at platform structure (can also self design), the center of the shaft shoulder main body cylinder 1 and mixing needle 3.Into long chamber 4
Bottom, heater strip 6 is installed in mixing needle 3, the telescoping mechanism 7 that heater strip 6 and driving mixing needle move up and down is controlled by control
Device 5 processed is simultaneously connected by respective conducting wire I 8 and conducting wire II 9 with controller 5 respectively, as shown in Figure 1.When it is implemented, telescopic machine
Bull electric pushrod can be used in structure 7, and when electric pushrod stretches out, stirring-head 3, which stretches out outside cavity 2, is stirred operation, stirring structure
Afterwards, electric pushrod retracts, and stirring 3 pushes back concordant with shaft shoulder main body cylinder 1, is stayed by the extruding of shaft shoulder main body cylinder 1 elimination mixing needle 3
Under key hole.Similarly, when it is implemented, telescoping mechanism 7 can be also electrostrictive mechanism, electrostrictive mechanism rises after energization
It opens and stretches out mixing needle outside cavity, stirring terminates, and power-off, deformation disappears, and mixing needle retracts in cavity 2.Similarly, telescoping mechanism
7 can also be hydraulic or pneumatic mechanism, and those skilled in the art can be designed corresponding hydraulic mechanism or pneumatic mechanism as needed.Make
For ideal telescoping mechanism 7, no matter it is conservation mechanism, preferably pre-fill is designed in shaft shoulder main body cylinder 1 with simplifying, as
Power transmission technology in the rotation of shaft shoulder main body cylinder 1 is a kind of technological means that electrician often fences, and the present invention is not described further in detail.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
