Cross the technological parameter to realize significantly improving.
Agitating friction welding is compared the welding of other forms and there may be some advantages.For example, agitating friction welding is not related to
And soldered part is heated to as the so high degree of the welding of other forms（Reach material melting point temperature）.In addition, stirring
Mix friction welding and need not use the solder flux or gas for being possible to pollutant be introduced weld seam.But with agitating friction welding technology
The expansion of application and becoming more meticulous for product manufacturing, propose higher requirement, table in the processing of existing product to solder technology
Reveal problems with：
1st, weld seam can be produced when tradition agitating friction weldering stirring tool is welded thinning, this will cause structural bearing section to reduce, and lead
Enable power declines.
2nd, in the occasion that Welded Joints mechanical property requirements are high, traditional agitating friction weldering stirring tool weld properties
It is difficult to pass through to change welding procedure realization raising.
3rd, traditional agitating friction weldering stirring tool can produce substantial amounts of overlap, and shaping surface is not good.
The content of the invention
It is an object of the invention to provide a kind of agitating friction welder and its method, to solve traditional agitating friction weldering
When stirring tool is welded, the weld seam that exists is thinning, weld properties are limited, weld seam has overlap.

Connection device head spindle connects；Mounting seat, is rigidly fixed with the ultrasonic generator.
Further, the mixing needle selects dimension according to weld size.
Further, the mixing needle is passed through from the axle center of the ultrasonic generator and the static shaft shoulder of the luffing, is passed through
The bearing of the mounting seat is co-axially mounted with ultrasonic generator, the static shaft shoulder of the luffing.
The present invention also provides the method that friction welding (FW) is stirred to workpiece using agitating friction welder, mixing needle rotation
Turn, stretch into inside weld seam, stirring metal is welded, and ultrasonic generator produces the dither of axial direction, by luffing stationary shaft
Shoulder amplifies and is applied to surface of the work, while power ultrasonic is input into inside weld metal, the static shaft shoulder of the luffing does not rotate,
It is pressed on the weld metal around the mixing needle.
The present invention provide agitating friction welder, simple structure, by arrange mounting seat, by ultrasonic generator,
The static shaft shoulder of luffing and mixing needle are combined into one, and are installed on agitating friction welder head spindle.
The method that the utilization agitating friction welder that the present invention is provided is stirred friction welding (FW) to workpiece, non-rotary change
The static shaft shoulder can be prevented effectively from the thinning generation of weld seam；By the dither of the static shaft shoulder of luffing, weldering can be thoroughly eliminated
Connect the generation of overlap；By the static shaft shoulder of luffing, Resistance of Weld Metal input power ultrasound, can preferentially improve seam organization, improve
The mechanical performance of weld seam.
