The soft shell in conical tubular, in the top of whole device, the top central authorities of soft shell arrange by Installing hole, the main tapping for connecting welding equipment is simultaneously sealed, and the lower surface of soft shell and flange connect, using connection Clip is connected, and the soft shell is mainly made using silica gel or PVC material, and its height can disappearing with stopper Consumption and pushing for main tapping and reduce, and have certain transparency to observe drainage situation and welding process.Soft shell, Flange, foam mat and surface of the work constitute air chamber, are substantially carried out the draining sealing of welding region.
The flange is in toroidal, and upper surface is connected with the lower surface of soft shell, uniform along circumference of flange Air inlet is set, and such as 4-6 air inlets using air inlet with draining, and maintain the shape of air chamber, keep the storage needed for air chamber Tolerance.
The flange lower surface is connected with the foam mat of toroidal, to keep air-tightness, prevent aqueous reflux.
The magnetic suction disc is connected with backing plate, and the backing plate is connected to the bottom of flange, the magnetic suction disc and backing plate Quantity is consistent, and the magnetic suction disc is uniformly distributed along circumference of flange direction, such as 4-6 magnetic suction discs;Magnetic suction disc can be with machine Tool is adjusted, and its major function is to fix the position of drainage arrangement, prevents not caused enough the water of soft shell rigidity in drainage procedure Cover is tumbled, or the vibrations in welding process cause drainage arrangement change in location etc..
The technical scheme of this method can be used for friction stitch welding welder equipment and various materials tested, in welding process The formation of welding overlap and the observation of welding stability, friction stitch welding welder equipment is capable of achieving under water using the equipment of the present invention The welding of optional position:Certain dimensioned sample is first according to, is assembled on welding machine main tapping, spring chuck is fixed, will Soft shell is fixed on main tapping, by clamp connection, then flange and soft shell is connected, and is equally connected using clip Connect, sponge is pasted in farad bottom, then assemble four connectors and be connected on magnetic stand, by magnetic-adsorption in workpiece table Face.Connection gas circuit is installed after sample and can be carried out experiment.Simultaneously start-up frequency, before welding starts draining is given, so that Horizontal plane is located under workpiece.Start friction stitch welding equipment, welding machine main shaft will be moved downward, soft shell short transverse is shunk, Sample and mother metal absorption surface, welding process starts, and whole process can pass through transparent soft shell and observe.By the present invention Technical scheme can obtain the joint of local dry underwater welding.
The present invention is for needed for the friction stitch welding under water Welding experiment of local dry cavity.It is folded that the experimental facilitiess are mainly used in friction The welding of weldering local dry cavity, can observe to ensureing the smooth enforcement of local dry cavity and intuitively welding process very much, from And the mechanism for more profoundly analyzing friction stitch welding is reached, optimize the effect of friction stitch welding technological parameter, the reason to friction stitch welding There is important meaning by research aspect.
