In order to ensure mark work quality, the spacing between stirring needle end part and the supporting surface of backing plate 6 is 0.2mm.
Embodiment 2：
As shown in figure 1, the present embodiment 2 and the difference of embodiment 1 are：When needs are beaten in cold drawing class workpiece surface
When marking but being groove below commissure, mark area can not be arranged on commissure, now mark portion 4 can be arranged on into labelling head
On, labelling head is detachably arranged on the handle of a knife of friction stir welding machine, and mark portion 4 is located in labelling head front end surface, as
Optional embodiment, mark portion 4 is the figure or word 5 caved inward.Labelling head is for circle at the top of hierarchic structure, labelling head
Fixing bolt side top surface 2 is provided with cylinder shape handle of a knife clamping part 1, the side wall of handle of a knife clamping part 1, fixing bolt side top surface 2 is flat
Labelling head is fixed under handle of a knife through being connected to fixing bolt side top surface 2 after the fixing hole on handle of a knife by face structure, fixing bolt
End, the quantity of fixing bolt side top surface 2 is at least two, and the lower end of handle of a knife clamping part 1 is labelling head body, labelling head body and knife
Vertical position limiting structure 3 is provided between handle clamping part 1, vertical position limiting structure 3 is plane, and the plane ensures handle of a knife clamping bottom
Extreme position.
When mark portion 4 is arranged on labelling head, mark work also comprises the following steps：
Step G：Processed in mark cephalic par in mark portion 4, and the figure or word 5 caved inward in mark portion 4
Smearing release agent；
Step H：It will treat that mark workpiece is fixed on the table, weld seam welding is carried out by friction stir welding machine, it is to be welded
Complete, the stirring-head on handle of a knife is removed, then labelling head is fixed on stirring-head；
Step I：Labelling head position is adjusted, is located at labelling head end and treats that mark workpiece surface is treated directly over mark area, so
After start friction stir welding machine, labelling head, which rotates at a high speed and dropped under handle of a knife drive, treats mark workpiece surface, labelling head
With treating that the friction of mark workpiece surface makes to treat that mark workpiece surface material occurs thermoplasticity and become under high speed rotation and upset force effect
Shape, the surfacing of generation pyroplastic deformation is extruded the figure caved inward in the mark portion 4 for being filled into mark cephalic par
Or in word 5；
Step J：Labelling head is stopped the rotation, and labelling head is lifted into completion after wait workpiece surface plastic deformation solidification-stable and beaten
Mark.
As a further improvement on the present invention, that treats mark workpiece treats that mark area should be flat surface, and treats that mark area should
For solid construction.
The mark location of workpiece should be flat surface, because mark process mark location is had compared with big load, should not choose
There is the surface of cavity inside as mark location, prevents the risk of the destruction workpiece such as be collapsed deformation.
Specifically used mode：
By agitating friction weldering butt welding spreading 500mm, thick 5mm 6061 material aluminium sheet sheet materials, enter at the back side of sheet material
Row mark " SCB " printed words.
Bottom support backing plate 6 when as shown in Figure 1 for welding, processes mark content for " SCB " mirror on backing plate 6
As printed words pit, depth is 0.15mm.
Step 1, thick 6061 aluminium sheets of 5mm to be welded are fixed using pressing plate, backing plate 6 is placed on below sheet material workpiece, is beaten
Marking-up sample should be in the underface of butt weld.
Step 2, mixing needle length is chosen to be mounted on handle of a knife for 4.6mm stirring-head.
Step 3, welding procedure is edited, the intrusion of stirring-head is set as 0.2mm, rotating speed is 1200rpm, and pace is
600mm/min。
Step 4, startup program, weld seam welding to be done, equipment is out of service, and mark is completed simultaneously.
Case two：Mark " SCB " printed words are carried out on the red copper cold drawing that agitating friction weldering is welded.
It is illustrated in figure 2 mark instrument schematic diagram：
Step 1, by mark workpiece place install on the table, labelling head is put into handle of a knife, vertical position limiting structure 3 with
After the end face of handle of a knife is close to, is tightened and be connected on fixing bolt side top surface 2 with side jacking nut.
Step 2, adjusting device makes labelling head in the surface of workpiece mark location, can only control device Z axis after adjusting
Movement carry out mark operation.
Step 3, edit routine, rotating speed is 1000rap, and the press-in workpiece surface depth of mark portion 4 is 0.5mm.
Step 4, startup program until equipment it is out of service, complete mark.
Step 5, changing needs mark workpiece to repeat mark.
In addition, if when beating the content for bearing serial numbers and needing to be continually changing, can first adopt the labelling head mark identical and consolidate
Fixed constant content, then this method labelling head numbered with unification group different digital, or coordinate other marking methods again as swashed
Light mark completes remaining content, so as to improve the efficiency of mark.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
