Description
Technical field
The present invention relates to a kind of large-sized aluminium alloy flat board agitating friction welding clamp, clamping is produced particular by electromagnet
The weld jig of power.
Background technology
Friction welding (FW) be mutually moved using workpiece end face, the heat produced by phase mutual friction, end is reached hot plastic state,
Then rapid upset, completes a kind of method of welding, is mainly used in solving the welding of the low melting materials such as aluminium alloy.
In rail traffic vehicles, a large amount of structural members using aluminum alloy materials.Limited by manufacturing process, its producer
Method produces the section bar similar to member structure generally by extruding aluminium alloy, then produces big chi by modes such as welding
Very little plate.Agitating friction has been welded into the major way of aluminium alloy panels welding.
The size of the aluminium alloy panels used when being manufactured due to rail traffic vehicles is generally larger, and fusion length is close to 20
Rice, the width of plate is close to 3 meters, it is necessary to arrange that 4 to 6 parallel weld seams could complete the welding of plate.As a result of certainly
Dynamicization manipulator carries out automatic welding, and the clamping of workpiece need to be completed once.To avoid fixture from being interfered with mixing needle, it will usually
Using two kinds of method of clamping.First, can only implement to fix by clamping the section bar on both sides, section bar in an intermediate position can only be
Fixed on the table in the presence of the section bar on side.Due to the deficiency of clamping force, aluminium alloy is stirred in welding process
The power of pin or thermal deformation cause weldment to tilt, and produce substandard product.Second, being entered by the telescopic arm of large span
Row clamping, but interference can be produced to mixing needle and machine tool chief axis, each weld seam is required for changing a clip position, influences work
Efficiency.
The content of the invention
For the deficiency of above-mentioned large-sized aluminium alloy flat board agitating friction welding clamp, the present invention provides one kind and passes through electromagnet
Produce the aluminum alloy welding welding fixture of absorption affinity.
To achieve these goals, present invention employs following technical scheme：
A kind of large-sized aluminium alloy flat board agitating friction weldering work clamping method, step is as follows：
(1) in welding bench floor installation electromagnet,
(2) the large-sized aluminium alloy flat board for needing to weld is well placed according to the status requirement of welding,
(3) the built-in cored length dimension press strip suitable with large-sized aluminium alloy flat board is attached to the upper of instrument
Side,
(4) it is powered to electromagnet and produces magnetic force so that electromagnet and the press strip being placed on above large-sized aluminium alloy flat board
Produce suction between interior iron core, by etc. large-sized aluminium alloy flat board to be welded be fixed on welding bench, it is to avoid weldering
Because the power by mixing needle or thermal deformation cause workpiece to tilt when connecing.
Compared with prior art, the beneficial effect that the present invention possesses：
The present invention can apply clamping force in the centre position of large-sized aluminium alloy plate, while the movement of Butt welding gun is not produced
Raw influence, drastically increases production efficiency, reduces the holding time of weldering bed.During large-sized Welded,
Press strip can be moved easily above aluminium alloy panels, according to the difference of welding position, quickly change its placement location.It is pressed from both sides
Clamp force is not influenceed by clamped position with the excessive generation of workbench Edge Distance.
Brief description of the drawings
Fig. 1 is the scene photo that large-sized aluminium alloy plate is welded.
Fig. 2 is the location diagram of the fixture.
Embodiment
Technical scheme is further elaborated below by embodiment.
Intend 20 meters of one block length of welding, wide 2.8 meters of flat aluminium alloy plate, the floor for producing rail traffic vehicles.Welding
The material of the flat board is 20 meters long by 5 pieces, 0.56 meter wide, aluminium alloy extrusions composition 0.03 meter thick.Design 4 20 meters long altogether
Stir friction welding seam.
A kind of large-sized aluminium alloy flat board agitating friction weldering work clamping method, step is as follows：
(1) in the floor installation electromagnet 4 of welding bench 3,
(2) the large-sized aluminium alloy flat board for needing to weld is well placed according to the status requirement of welding.
(3) the built-in cored length dimension press strip 1 suitable with large-sized aluminium alloy flat board is attached to large scale aluminium
The top of alloy plate, be specially：In five blocks of aluminium alloy extrusions 2, two pieces of outermost is carried out by the plain clamp 6 originally welded on bed
Clamping.The top placement iron core press strip 1 of middle three pieces, wherein heart position.The size of iron core press strip 1 is 21 meters of length, wide
It is 0.15 meter, high 0.3 meter.Wherein one end of iron core press strip 1 is designed with guide wheel 5, can be quick from wherein one end of aluminium alloy extrusions 2
It is routed to the top of aluminium sheet.Corresponding to the placement location of press strip 1, it is provided with the welding bench 3 of the lower section of aluminium alloy extrusions 2
Electromagnet 4, the length of electromagnet 4 is 20 meters, and width is 0.15 meter.
(4) it is powered to electromagnet and produces magnetic force so that electromagnet and the press strip being placed on above large-sized aluminium alloy flat board
Produce suction between interior iron core, by etc. large-sized aluminium alloy flat board to be welded be fixed on welding bench, it is to avoid weldering
Because the power by mixing needle or thermal deformation cause workpiece to tilt when connecing.Specially：Press strip 1 is placed on correct position
Afterwards, electromagnet 4 is powered, then proceeds by welding.After the completion of welding, electromagnet 4 is powered off, electromagnet 4 loses magnetism, then
Press strip 1 is taken out.
Present invention is mainly used for the welding that length and width reaches aluminium alloy panels below more than 2.5m, 0.05 meter of thickness, welding position
With the Edge Distance of welding bench 3 more than 2 meters, plain clamp 6 leads to not enter on the position periphery of weld seam 7 because span is excessive
The situation that row is clamped.The profile of press strip 1 is the rod member of square section, and installation direction is consistent with bead direction when using, and it is provided
Clamping force perpendicular to aluminium alloy panels.
