Background technology
Friction stir welding is a kind of novel Material Joining Technology.Make material to be welded be in a kind of fritting state in commissure by the High Rotation Speed of mixing needle in commissure and fricative heat, by the effect of mixing needle, the material on weld seam both sides is linked together afterwards.Because material does not melt completely, doing so avoids the generation of the defect that some easily occur under melting welding state.Simultaneously can not produce the pollutants such as waste gas in the process using friction stir welding, shown in say that friction stir welding is a kind of green welding technology efficiently.Based on the many merits of friction stir welding, increasing user selects friction stir welding to replace traditional melting welding to connect.But because friction stir welding is different with the mechanism of action of traditional melting welding, the auxiliary mould of friction stir welding needs larger rigidity, thus improves the design difficulty of auxiliary mould.
Large revolving body part, due to the thick and heavy property of its part self, adds that stirring friction-welding technique feature determines that the supporting die tire of needs in melon lobe fitted underneath high rigidity is to support the forging force of mixing needle.The laminating degree of mould tire and workpiece very broad aspect have impact on the quality that agitating friction welds.Simultaneously in stir friction welding process, there is very large tension force the both sides along weld seam, need to be overcome by side tension by the hold-down mechanism of frock.Due to front road production process and the design feature of self, often there is position while welding camber line low precision, the problem that deflection is large, need frock to give certain rectification in melon lobe part.Weld seam is a full circle shape, and the pressing system above weld seam cannot be connected with rectangular structure.And the specification of cylinder part is many, need the welding of compatible many kinds of specification part.
Summary of the invention
For problem existing in existing weld parts frock, a kind of structure simple revolving parts circumferential weld agitating friction is provided to weld frock.Frock of the present utility model technical problem to be solved designs the compatible multiple cylinder part hold down gag of a kind of energy, design the welded and installed mould tire of sufficient intensity, have certain correcting function to workpiece and efficiency of assembling can be improved and ensure welding quality and precision simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of revolving parts circumferential weld agitating friction welding frock, it is characterized in that, comprise: base, be connected to the supporting die tire on base, be arranged on the lower pressing system outside supporting die tire and upper pressing system, and pressure holding is at the Weighting system on upper pressing system top, lower pressing system and upper pressing system are buckled together mutually, described supporting die tire comprises some pieces and supports backing plate, described lower pressing system is provided with the lower hold down gag that screw rod regulates, described upper pressing system is provided with several hold-down mechanisms.
In the utility model preferred embodiment, described base, described supporting die tire, described upper pressing system and described lower pressing system are rotary structure.
In the utility model preferred embodiment, described upper pressing system and described lower pressing system are all around being arranged on described supporting die tire periphery.
In the utility model preferred embodiment, each described support backing plate two ends connect pneumatic mechanism and spiro rod regulating device respectively.
In the utility model preferred embodiment, described lower hold down gag is two annulus connected by several screw rods, and described in two, annulus is coaxially arranged.
In the utility model preferred embodiment, each described hold-down mechanism is arranged on several bracing frames of described upper pressing system, and described hold-down mechanism is movably fixed on support frame as described above.
In the utility model preferred embodiment, described Weighting system, described upper pressing system and described lower pressing system are coaxially arranged from top to bottom successively.
In the utility model preferred embodiment, described Weighting system comprises mandrel, and the some pieces of balancing weights through mandrel.
In the utility model preferred embodiment, described Weighting system pressure holding is on described on pressing system.
Existing welding tooling mainly exists that clamping is loaded down with trivial details, inefficiency, heavy, need many cover frocks realize the problems such as the welding of different size cylinder part.Frock of the present utility model adopts many adjustable structures, will adopt different installation site for different size cylindrical workpieces, reduces frock tricks.Weighting system provides continual and steady thrust in welding process, once completes the welding of whole piece circumferential weld, ensure that welding precision, improves the welding quality of weld seam and greatly improves welding efficiency.
