Abstract
The invention discloses a kind of fillet weld Friction Stir Welding flexible frocks, realize the Friction Stir Welding of the inner side and outer side fillet weld of different-thickness workpiece.Two identical cushion blocks are bolted by fixed block, form workpiece mounting platform.By adjusting being screwed into depth and adjusting splint position for bolt, and then the workpiece is driven to move upwards along cushion block surface, to be aligned fillet weld.Pressing plate is fixed workpiece by fastening bolt, clamps, and realizes the clamping of fillet weld on the outside of workpiece.The position for exchanging two cushion blocks, ressembles remaining parts, can carry out the clamping of fillet weld on the inside of workpiece.The tooling realizes the clamping of inner side and outer side fillet weld workpiece, and can realize the clamping and positioning of different-thickness workpiece by set of parts.By replacing various sizes of cushion block, it can be achieved that the fillet weld workpiece of different angle welds.
Description
Technical field
The present invention relates to welding toolings, in particular to a kind of to be used for fillet weld Friction Stir Welding, it can be achieved that different-thickness
The flexible frock of the inner side and outer side fillet weld seam of workpiece.
Background technique
Agitating friction welding technology makes its application in the huge technical advantage that low-melting alloy structure manufacturing field embodies
Extension rapidly.Its exclusive solid diffusivity feature, so that in bonding strength, deformation and residual stress level, corrosion resistance
Energy etc. has advantage.It has been widely used in the neck such as aerospace, high speed railway car, automobile, ship, weapons at present
Domain.
In practical structures, largely there is that fillet weld is this kind of non-planar or the joint form of non-approximated plane.Due to stirring
In friction welding process, workpiece needs solid back-supported, is used for the tooling of fillet weld fusion welding not in existing patent
It is applicable in agitating friction weldering.And it is directed to the Friction Stir Welding of fillet weld, the prior art passes through mostly increases technique cushion block, is converted into
It is realized similar to the butt-welded measure of plane.But this tooling easily causes welded seam area lack of penetration, Weak link etc. occur
Defect, and the utilization rate of technique cushion block is low, the welding of inner side and outer side fillet weld usually requires two sets of toolings and realizes respectively, cost
It is higher.Not yet occur the related patents of fillet weld Friction Stir Welding special tooling at present.Therefore, develop a kind of structure it is simple,
Versatility it is good, it can be achieved that the inner side and outer side fillet weld Friction Stir Welding of different-thickness workpiece flexible frock, for reduce
Cost improves Product jointing quality and qualification rate, has great importance.
Summary of the invention
Present invention aim to address above-mentioned the deficiencies in the prior art, provide that a kind of structure is simple, different-thickness can be achieved
The flexible frock of the inner side and outer side fillet weld Friction Stir Welding of workpiece.
A kind of fillet weld Friction Stir Welding flexible frock, comprising: two identical cushion blocks, link block, fixed block, tune
Locking nub, clamping plate and pressing plate；The cushion block is installed by the bolt connection on the link block by the cushion block surface composition workpiece
Platform；The fixed block is mounted on the cushion block by screw, and is fixed by bolt and platen；The pressing plate is logical
It crosses screw to be mounted on the cushion block, the bolt on the pressing plate can be to different-thickness Workpiece clamping and positioning；The clamping plate is put
It sets on the surface of the cushion block, to clamp workpiece, and workpiece is driven to move along the workpiece mounting platform, thus alignment angle
Weld seam, the clamping plate are contacted with the adjusting block；It is screwed into adjusting bolt in the tapped through hole of the adjusting block, passes through the adjusting
Bolt adjusts the position of the clamping plate, and the adjusting block is mounted on the cushion block by screw.
Preferably, link block is at least arranged 2 in the junction of the cushion block.
Preferably, there are gap between two adjacent link blocks, interstice coverage is about 2mm~4mm.
Preferably, the welding of the fillet weld workpiece of different angle is adjusted by adjusting the cushion block of different surfaces.
A kind of application method of fillet weld Friction Stir Welding flexible frock,
Step 1: after identical two cushion blocks connect bolt fastening by the bolt on the link block, described two
A cushion block fitting, surface composition workpiece mounting platform；
Step 2: the fixed block is mounted on the cushion block by screw, and is fixed by bolt and platen,
Complete the fixation of the flexible frock；
Step 3: the clamping plate is placed on the surface of the cushion block；Adjusting is screwed into the tapped through hole of the adjusting block
Bolt, the position of the clamping plate is adjusted by the adjusting bolt, and the adjusting block is mounted on the cushion block by screw；
Step 4: workpiece is placed on clamping plate, by the position for being screwed into depth adjustment clamping plate for adjusting bolt, in turn
Workpiece is driven to move along the workpiece mounting platform, to be aligned fillet weld；
Step 5: the pressing plate is mounted on the cushion block by screw, and the bolt is screwed into the tapped through hole of pressing plate,
The bolt is tightened, the clamping of workpiece is completed.
Preferably, the position of cushion block is exchanged, the clamping of different fillet welds can be carried out.
A kind of fillet weld Friction Stir Welding flexible frock provided by the invention and its application method and prior art phase
Than the advantage is that: flexible high, at low cost, a set of tooling can realize the inner side and outer side fillet weld of different-thickness workpiece
Clamping；It can be directly realized by the Friction Stir Welding of fillet weld, without being converted to plane butt welding, welded seam area is avoided and do not weld
Thoroughly, the defects of Weak link, welding quality is improved.
