Summary of the invention
The purpose of this utility model be to provide a kind of can avoid in welding process stirring-head to come off and stirring-head under the problem that comes off of the shaft shoulder, and there is the twin shaft shoulder stirring-head of easy-to-dismount advantage.To solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of agitating friction welding is takeed on stirring-head with twin shaft, comprises and stirs on headgear, stirring-head reducing sleeve, stirring-head the shaft shoulder, bolt under the shaft shoulder, mixing needle, stirring-head.Described stirring-head reducing sleeve is connected to the centre position of stirring headgear and stirring-head, and on described stirring-head, on the shaft shoulder, part is connected with stirring-head reducing sleeve, and under described stirring-head, the shaft shoulder is threaded connection with mixing needle and is connected as a single entity.
As further program of the utility model: described mixing needle Cross section Design is three tangent planes and four tangent planes, designs the screw thread of different rotation directions on mixing needle cylindrical.
As further scheme of the utility model: described stirring headgear is connected on machine tool chief axis by eight bolts, stir headgear connecting machine tool and stirring-head.
As further program of the utility model: described stirring-head reducing sleeve is connected to stirring-head by four bolts and puts.
As further program of the utility model: on stirring-head, under the shaft shoulder, stirring-head, the shaft shoulder and mixing needle are threaded connection.
As further program of the utility model: under described stirring-head, the shaft shoulder and pre-load nut are made of one.
Compared with prior art, the beneficial effects of the utility model are: the problem that can effectively avoid stirring-head in twin shaft shoulder stir friction welding process headgear comes off from stirring, the shaft shoulder comes off from mixing needle stirring-head; And the utility model is convenient to change stirring-head, is saved the soldering appliance clamping time.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-5, in the utility model embodiment, the welding of a kind of agitating friction is takeed on stirring-head with twin shaft, comprises and stirs on headgear 1, stirring-head reducing sleeve 2, stirring-head the shaft shoulder 5 and bolt 6 under the shaft shoulder 3, mixing needle 4, stirring-head.Described stirring-head reducing sleeve 2 is connected to the centre position of stirring headgear 1 and stirring-head by four bolts 6, on described stirring-head, on the shaft shoulder 3, part is connected with stirring-head reducing sleeve 2, under described stirring-head, the shaft shoulder 5 is made of one with pre-load nut, be threaded connection with mixing needle 4 and be connected as a single entity, the shaft shoulder 3 on described stirring-head, under stirring-head, the shaft shoulder 5 is threaded connection with mixing needle 4, described stirring headgear 1 is connected on machine tool chief axis by eight bolts 6, stir headgear 1 connecting machine tool and stirring-head, described mixing needle 4 Cross section Design are three tangent planes and four tangent planes, on mixing needle 4 cylindricals, design the screw thread of different rotation directions.
Operation principle of the present utility model is: stir headgear 1 and be connected on machine tool chief axis by eight M6 bolts, stir headgear 1 connecting machine tool and stirring-head, transferring power.Stirring-head reducing sleeve 2 is connected to stirring-head by four M4 bolts and puts, and ensures that stirring-head reducing sleeve is enclosed within process and does not separate with stirring-head; Its lower end is connected with stirring-head matched in clearance, the unthreaded hole that partly runs through in 90 ° in side, connecting bolt head 6.On mixing needle 4 and stirring-head, under the shaft shoulder 3, stirring-head, the shaft shoulder 5 is threaded connection, and thread rotary orientation can ensure that, in stirring-head rotary course, the shaft shoulder does not separate with mixing needle.On stirring-head, two planes of cutting in 90 ° are divided on the shaft shoulder 3 tops, beat respectively M5 screwed hole in plane, after the shaft shoulder on stirring-head 3 coordinates with stirring-head reducing sleeve 2, position carry-over moment by side bolt.Shaft shoulder surface design is counterclockwise groove, is conducive to material and draws close to center.Under stirring-head, the shaft shoulder 5 is made of one with pre-load nut, prevent mixing needle from nut because thermal deformation is different, the phenomenon that causes nut to come off.Mixing needle 4 Cross section Design are three tangent planes or four tangent planes, can play effective stirring action to material; At the contrary screw thread of mixing needle surface design rotation direction, be conducive to plastic material and draw close to intermediate cross-section simultaneously.
