Description
Technical field
The utility model relates to a kind of Friction welding technique, is specifically related to a kind of agitating friction jockey that can reduce overlap.
Background technology
Friction stir welding (FSW) is a kind of novel solid phase joining technique, when using this technology to weld, stirring-head rotates with constant speed and presses setting track uniform motion, insert material internal by mixing needle to stir, and the strong friction effect of the shaft shoulder of stirring-head and mother metal, the metal material in heat affected area is made to be in a kind of solid solution condition, mother metal maximum temperature is no more than fusing point, under the acting in conjunction of stirring-head and mixing needle, the metal of welded seam area is joined together, and finally completes whole welding process.
In welding process, when the shaft shoulder press-in materials to be welded of stirring-head is excessive, easily causes side or both sides metal to overflow the stirring-head shaft shoulder, form skim metal in shaft shoulder periphery after cooling, be overlap.Although the existence of overlap does not affect the mechanical property of joint usually, affect the attractive in appearance of weld seam.Meanwhile, the formation of overlap occurs with sheet material thinning often simultaneously, weld seam upper surface shaft shoulder place can be caused like this to form stress and concentrate, if do not carry out processing and directly test splice mechanical property will cause certain error.Therefore remove overlap and have its necessity.Welding of being everlasting in production terminates rear another increase deflashing operation, compares and wastes time and energy.The utility model will provide one to reduce workpiece deformation exactly, removes overlap, improves welding quality, reduces the jockey of follow-up deflashing workload.
Utility model content
The utility model provides a kind of energy fixation workpiece, reduces workpiece deformation, removes overlap, and can improve the agitating friction jockey of welding quality.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of agitating friction jockey that can reduce overlap, comprise stirring-head main body and sleeve 7, stirring-head main body comprises shaft 1, be fixed on the big column 2 on friction-welding machine, shaft below big column 2 is fixed with the first gear 3, the stirring-head shaft shoulder 4 and mixing needle 5 are set below first gear, shaft 1, first gear 3, the stirring-head shaft shoulder 4 and mixing needle 5 coaxial rotation, first gear 3 is outside equipped with the second gear 6 engaged with the first gear 3, second gear 6 axle center apertured, central shaft 9 is provided with in hole, central shaft 9 is fixed on big column 2, outside second gear 6, cylindrical shape sleeve 7 is set, sleeve 7 inner surface arranges the internal tooth 8 engaged with the second gear 6.
Preferably, the second gear 6 quantity is 4.
Preferably, leave appropriate gap between sleeve 7 and stirring-head main body, ensure not contact between sleeve and stirring-head main body, so in the course of the work, sleeve does not rotate with stirring-head.
Preferably, described mixing needle 5 is space curve revolving structure.
Preferably, the material of the described stirring-head shaft shoulder 4 bottom surface is polishing sand.
Preferably, the material of described sleeve 7 bottom surface is polishing sand.
The advantage that the utility model has and beneficial effect: a kind of agitating friction jockey removing overlap that the utility model proposes, by improving the external device (ED) of stirring-head, increase sleeve, by the bottom of sleeve and the contact of workpiece, the greasy dirt, oxide etc. of surface of the work to be welded is eliminated in stirring-head direction of advance, the impurity of weld seam is reduced, contribute to the raising of weldquality, remove overlap, smooth in appearance is smooth, also eliminate the impact of overlap welding quality, and save follow-up deflashing operation, time saving and energy saving.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the sectional view of Figure 1A-A;
Fig. 3 is the schematic diagram of mixing needle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of agitating friction jockey that can reduce overlap, comprise stirring-head main body and sleeve 7, stirring-head main body comprises shaft 1, be fixed on the big column 2 on friction-welding machine, shaft below big column 2 is fixed with the first gear 3, the stirring-head shaft shoulder 4 and mixing needle 5 are set below first gear, shaft 1, first gear 3, the stirring-head shaft shoulder 4 and mixing needle 5 coaxial rotation, first gear 3 is outside equipped with the second gear 6 engaged with the first gear 3, second gear 6 axle center apertured, central shaft 9 is provided with in hole, central shaft 9 is fixed on big column 2, outside second gear 6, cylindrical shape sleeve 7 is set, sleeve 7 inner surface arranges the internal tooth 8 engaged with the second gear 6, second gear 6 quantity is 4, appropriate gap is left between sleeve 7 and stirring-head main body, ensure not contact between sleeve and stirring-head main body, so in the course of the work, sleeve does not rotate with stirring-head, described mixing needle 5 is space curve revolving structure, the material of the described shaft shoulder 4 bottom surface is polishing sand, the material of described sleeve 7 bottom surface is polishing sand.
The implementation process of welding job is as follows:
Welding starts, main shaft drives stirring-head to rotate, first gear synchronous rotates, first gear driven second pinion rotation, second gear driven sleeve rotates, because big column going down pressure is on sleeve, such sleeve just can workpiece pressing in workpiece motion s process, remove overlap, because sleeve is positioned at the second gear exterior, its rotating speed is lower than the rotating speed of main shaft, the wearing and tearing of sleeve bottom surface are less, in the region of postwelding, the overlap that stirring-head and workpiece agitating friction process produce, just can be removed by the contact of sleeve bottom.
