Abstract
The utility model provides a clamp for a preposed heat source, which is applicable to a friction stir welding process in preposed heat source assistance. Four moving directions of the head part of friction stir welding equipment are respectively provided with a preposed heat source clamp which is completely the same; each preposed heat source clamp comprises a preposed heat source clamp head, a horizontal adjustable lever, a vertical adjustable lever, a fixed base, an adjusting screw A and an adjusting screw B; the preposed heat source clamp head adopts a numerical control machine universal tool clamp, and the front end of the preposed heat source clamp head is fixed with an elastic card through an inverse locking ring; the fixed base is fixed on a friction stir welding gun; one end of the vertical adjustable lever is connected with the fixed base through the adjusting screw B, and the other end of the vertical adjustable lever is connected with the horizontal adjustable lever through the adjusting screw A; and the other end of the horizontal adjusting lever is connected with the preposed heat source clamp head. The clamp has the advantages of simple structure, adjustable heat position, good vibration reduction effect and accurate positioning.
Description
Technical field: the utility model relates to a kind of anchor clamps, and especially a kind of auxiliary preposition thermal source of friction stir welding technology down of preposition thermal source that is applicable to is used anchor clamps, belongs to welding technology field.
Background technology: as a kind of solid phase interconnection technique, do not have the fusing of material and solidification phenomenon to produce in the stir friction welding process, therefore have advantages such as low stress, small deformation, high strength, green non-pollution.But for high-melting-point Materials with High Strength (titanium alloy, steel etc.); There are some problems in the friction stir welding process: 1) in order to guarantee welding temperature; Need very large upset force in the welding process, thus the anchor clamps that need enough rigidity with the clamping that guarantees test specimen to be welded with fixing; 2) be applicable to that the abrasion condition of the stirring tool (such as the tungsten-rhenium alloy stirring tool) under the condition of high temperature is very serious.Above-mentioned reason has hindered the practical engineering application of agitating friction welding technology at the high-melting-point structural member greatly.At present, select laser, plasma arc etc. to assist the process of friction stir welding to have report, but the special fixture of preposition thermal source is directed to specific preposition thermal source design often, therefore has shortcoming poor for applicability as preposition thermal source.
Summary of the invention: have in order to solve friction Stir high-melting-point Materials with High Strength that anchor clamps rigidity is big, the problem of stirring tool serious wear; Friction stir welding technology based on preposition thermal source under auxiliary, the utility model provides a kind of preposition thermal source special fixture that is applicable to multiple thermal source type.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: the preposition thermal source that is applicable to the auxiliary following friction stir welding technology of preposition thermal source is used anchor clamps; On the four direction of friction stir welding equipment head (1) motion identical preposition thermal source anchor clamps (3) are installed respectively, preposition thermal source anchor clamps (3) by preposition thermal source with anchor clamps head (4), levelling lever (5), vertical adjusting rod (6), firm banking (7), adjustment screw A (8) and adjustment screw B (9).Preposition thermal source adopts Digit Control Machine Tool universal cutter anchor clamps with anchor clamps head (4), and its front end is fixed with elastic card (11) through contrary binding ring (10).Firm banking (7) is fixed on the friction stir welding welding gun (2).Vertically adjusting rod (6) one ends are connected with firm banking (7) through adjustment screw B (9), and the other end is connected with levelling lever (5) through adjustment screw A (8).The other end of levelling lever (5) connects preposition thermal source with anchor clamps head (4).
The utility model is simple in structure, heating location is adjustable, good damping result, accurate positioning; Match with preposition thermal source (like laser, electric arc, oxy-acetylene etc.); Effectively reduce the wearing and tearing of stirring tool in welding process and the rigidity that reduces welding jigs and fixtures, help further popularization and the use of agitating friction welding technology in structures such as the titanium alloy in fields such as Aeronautics and Astronautics, automobile, steel.

Fig. 2 is the structural representation of preposition thermal source anchor clamps.
Fig. 3 is the structural representation of preposition thermal source with the anchor clamps head.
The specific embodiment:
Like Fig. 1-shown in Figure 3; The preposition thermal source that is applicable to the auxiliary following friction stir welding technology of preposition thermal source is used anchor clamps; On the four direction of friction stir welding equipment head 1 motion identical preposition thermal source anchor clamps 3 are installed respectively, preposition thermal source anchor clamps 3 by preposition thermal source with anchor clamps head 4, levelling lever 5, vertical adjusting rod 6, firm banking 7, adjustment screw A8 and adjustment screw B9.Preposition thermal source adopts Digit Control Machine Tool universal cutter anchor clamps with anchor clamps head 4, and its front end is fixed with elastic card 11 through contrary binding ring 10.Turn binding ring 10 counterclockwise and just can cause inner elastomeric card 11 loosening, take out heat power supply device, turn binding ring 10 clockwise and just can cause 11 lockings of inner elastomeric card, firmly grasp heat power supply device.Firm banking 7 is fixed on the friction stir welding welding gun 2.Vertically adjusting rod 6 one ends are connected with firm banking 7 through adjustment screw B9, and the other end is connected with levelling lever 5 through adjustment screw A8.The other end of levelling lever 5 connects preposition thermal source with anchor clamps head 4.
Before each welding, can select suitable anchor clamps as required, preposition thermal source adopts Digit Control Machine Tool universal cutter anchor clamps with anchor clamps head 4.Before implementing welding; Thermal source is clamped on the preposition thermal source anchor clamps head 4 at present; Respectively levelling lever 5 and vertical adjusting rod 6 are regulated through adjustment screw A8 and adjustment screw B9; Preposition thermal source is adjusted to suitable position, will adjust screw A8 and adjustment screw B9 locking then, just can come into effect welding.
