Description
Technical field
The invention belongs to engineering manufacturing technology fields, are related to a kind of assist type agitating friction weldering for collecting mechanical stitch and polishing
It picks.
Background technology
After agitating friction welding, workpiece can generate residual stress, and can so that the plate thickness of commissure is slightly below original
Thickness of slab value.Residual stress can be reduced and improved by heat treatment, but cannot be completely eliminated, and cost is higher.It stirs
Mixing friction welding component residual stress has tensile stress also to have compression, and compression is normally at except weld seam, and tensile stress will appear
Near stirring area, heat-mechanical affected zone and heat affected area, and peak value can generally generate the range near shaft shoulder outer edge, stretch
Residual stress can with workpiece be on active service working stress be superimposed, reduce the workpiece service life after military service.
Invention content
The problem to be solved in the present invention is residual stress and increase welding region geometric height in weld seam, is proposed a kind of
Collect mechanical stitch and the assist type agitating friction bonding machine of polishing, its significance lies in that improving agitating friction welded unit welding region
Tensile stress distribution, reduce tensile stress numerical value and residual tension be even converted into compression, and realize welding and polished
Journey, which synchronizes, to be carried out.
Technical scheme of the present invention：
It is a kind of to collect mechanical stitch and the assist type agitating friction bonding machine of polishing, including welding system, polishing system, rolling
System, workpiece 2 and increasing material plate 8；
The welding system, including live spindle 1, the shaft shoulder 10 and mixing needle 9；The shaft shoulder 10 is fixedly mounted on rotation
Turn the lower face of main shaft 1, the mixing needle 9 is fixedly mounted on the lower face of the shaft shoulder 10, live spindle 1, the shaft shoulder 10 and stirring
The center of needle 9 is on same axis；The live spindle 1 drives the shaft shoulder 10 and then mixing needle 9 is driven to rotate, and is the shaft shoulder 10
Pressure under being provided in welding process is stirred with mixing needle 9, live spindle 1 itself do translational motion along weld seam 3；
The polishing system, including polishing pad 4, idler wheel 5, motor 6 and slide plate 13；After the polishing pad 4 and welding
And the upper surface for carrying out the weld seam 3 of mechanical stitch is in contact, and rotation is driven by motor 6；The slide plate 13 is equipped with
The frame structure of through-hole, through-hole thereon connect for motor 6 with polishing pad 4；The bottom both ends at 13 both ends of slide plate are equipped with idler wheel
5, making it, the i.e. direction of weld seam 3 is moved forward and backward along 2 boundary slip of workpiece；
The rolling system, including mechanical rollers 7；The mechanical rollers 7 are placed in the lower section of slide plate 13, weld seam 3
Top, width are consistent with the diameter of the shaft shoulder 10；
The workpiece 2 is plate to be welded；
The increasing material plate 8 is the thin plate that 3 upper surface of weld seam is layed in before welding.
During work, two pieces of workpiece 2 to be welded are fixed on the table, is laid on weld seam 3 and is increased material plate 8 and fix,
Polishing system and rolling system are installed；Mixing needle 9 is pressed into workpiece 2, and revolving using the pressure that the shaft shoulder 10 applies by material plate 8 is increased
Turn to carry out high speed rotation under the driving of main shaft 1, sufficient heat for welding process is provided, passes through the rotation and translation of mixing needle 9
Realize solid State Welding；
Polishing system and rolling system keep translational motion along weld seam 3, are remained unchanged with the relative position of welding system；It is first
It polishes first with 4 butt welding rear region 12 of polishing pad, makes 11 surfacing of polishing rear region, rolled convenient for mechanical rollers；So
Polishing rear region 11 is rolled using mechanical rollers 7 afterwards, weld seam 3 is compacted, 3 tensile stress of weld seam is reduced and is even changed into pressure
Stress so as to improve the mechanical property of weld seam 3 and fatigue strength, improves prepared welding workpiece service life.
Beneficial effects of the present invention：The collection mechanical stitch of the present invention is fully tied with the assist type agitating friction bonding machine polished
The advantage of the subjects such as structural mechanics, Machine Design is closed, above-mentioned welding function can be fully realized and improve the mechanics of weld seam
Performance improves welding quality, reduces production cost.The present invention effectively prevents in a manner that advance laying increases material plate
Welding process is since shaft shoulder press-in workpiece reduces the problem of welding region geometric height is less than former workpiece height, so as to greatly improve
The mechanical performance of agitating friction welded unit.
Description of the drawings
Fig. 1 is a kind of assist type agitating friction bonding machine for collecting mechanical stitch and polishing.
In figure：1 live spindle；2 workpiece；3 weld seams；4 polishing pads；5 idler wheels；6 motors；7 mechanical rollers；8 increase material plate；9 stir
Mix needle；10 shaft shoulders；11 polishing rear regions；12 postwelding regions；13 slide plates.
Specific embodiment
Below in conjunction with attached drawing and technical solution, the specific embodiment further illustrated the present invention.
Two pieces of workpiece 2 to be welded are fixed on the table, is laid on weld seam 3 and increases material plate 8 and fixed, installation polishing system
System and rolling system；The pressure press-in that mixing needle 9 is applied using the shaft shoulder 10 increases in material plate 8 and workpiece 2, and in live spindle 1
Driving is lower to carry out high speed rotation, and sufficient heat is provided for welding process, and solid-state welding is realized by the rotation and translation of mixing needle 9
