Abstract
The utility model discloses a two side dead axle shoulder stirring heads of self -adaptation has cup jointed the shaft shoulder and the lower shaft shoulder on the shank -pin of the first main part one end of stirring, the rear end of wherein going up the shaft shoulder is connected with thrust ball bearing, and the front end of the lower shaft shoulder is connected with deep groove ball bearing, is equipped with elastomeric element between the lower shaft shoulder and the deep groove ball bearing, deep groove ball bearing, elastomeric element, down the shaft shoulder, upward the shaft shoulder and thrust ball bearing fix through a chassis and concatenate on shank -pin in proper order. Beneficial effect: go up the shaft shoulder and the clearance automatically regulated between the shaft shoulder down, so not only reduced the shaft shoulder and the heat input that the mother metal friction produced, improved the mechanical properties of welding seam, too big and among the messenger welding process a large amount of overlap and the burrs of production of the first shaft shoulder clamping -force of biax shoulder stirring that has avoided traditional structure in addition. Both improved the whole quality after the automobile body is assembled, and significantly reduced again and repaired the man -hour that weld defects consumed.
Description
Technical field
The utility model relates to a kind of stirring-head, particularly a kind of self adaptation bilateral dead axle shoulder stirring-head.
Background technology
In recent years, along with the continuous research and development of high ferro technology, China has become few in number in the world can produce the country of high speed railway track passenger vehicle by designed, designed, the market share of contention world high ferro order rises to State-level, and can the quality and safety of high ferro be the inter-State prerequisite taking down order in competition.
Because current domestic manufacturing technology is more conservative, the most long straight weld of high-iron carriage car body still adopts traditional MIG welding, widget adopts agitating friction welding, and there is a big difference compared to mother metal for the mechanical property of weld seam, and therefore the mechanical property of weld seam has larger room for promotion.The arc-welding that agitating friction solder technology is more traditional is compared, and the mechanical property of weld seam improves a lot.By the research for traditional single shaft shoulder and double-shaft shoulder stirring-head soldering test, identical welding parameter place an order shaft shoulder stirring-head compared to the welding of double-shaft shoulder stirring-head after the mechanical property of weld seam high a lot, and heterogeneous microstructure improves, and for the welding of high-iron carriage aluminum alloy hollow section, single shaft shoulder stirring-head does not reach manufacture process requirement.Although double-shaft shoulder stirring-head can meet the technological requirement of the welding of aluminum alloy hollow section, easily produce a large amount of overlap and burr after welding, and mechanical property has to be hoisted.Therefore it is imperative how double-shaft shoulder stirring-head and single shaft shoulder stirring-head advantage to be separately integrated together.
Summary of the invention
The purpose of this utility model is that a kind of self adaptation bilateral dead axle provided takes on stirring-head in order to solve the problem that there is more deficiency in existing single shaft shoulder, the welding of double-shaft shoulder agitating friction.
The self adaptation bilateral dead axle shoulder stirring-head that the utility model provides is on the mixing needle of stirring-head main body one end, be socketed with the shaft shoulder and the lower shaft shoulder, the rear end of wherein going up the shaft shoulder is connected with thrust ball bearing, the front end of the lower shaft shoulder is connected with deep groove ball bearing, be provided with elastomeric element between the shaft shoulder and deep groove ball bearing down, deep groove ball bearing, elastomeric element, the lower shaft shoulder, the upper shaft shoulder and thrust ball bearing are serially connected on mixing needle successively by a chassis is fixing.
Stirring-head main body and mixing needle as a whole, adopt H13 steel to do.
Mixing needle offers three and cut sword, cut between sword spaced in hexagonal angle.
Elastomeric element is a spring, and this spring is located in the groove offered lower shaft shoulder front end.
Be fixed by being spirally connected between chassis with mixing needle and be connected.
The upper shaft shoulder, the lower shaft shoulder and chassis all adopt ordinary low-alloy steel to make.
The model of deep groove ball bearing is 6000-2RS, and the model of thrust ball bearing is 51100.
Operation principle of the present utility model:
The self adaptation bilateral dead axle shoulder stirring-head that the utility model provides can be applied to the welding of the long straight weld of the hollow extrudate of high Fe in Al-alloy car body, gap in welding process on stirring-head between the shaft shoulder and the lower shaft shoulder can adapt to the thickness of sheet material automatically, greatly reduces due to the upper shaft shoulder and lower shaft shoulder chucking power excessive and the welding burr caused and overlap.In welding process, only have mixing needle rotation to complete with mother metal frictional heat to weld, and the upper shaft shoulder and the equal non rotating of the lower shaft shoulder, greatly reduce thermal weld stress, mixing needle by remarkable crystal grain thinning, improves the mechanical property of welding product for the stirring fragmentation of weld metal greatly.
The beneficial effects of the utility model:
The self adaptation bilateral dead axle shoulder stirring-head that the utility model provides is carrying out the shaft shoulder and the equal non rotating of the lower shaft shoulder in welding process, and the gap between the upper shaft shoulder and the lower shaft shoulder regulates automatically, so not only decrease the shaft shoulder and the fricative heat of mother metal inputs, improve the mechanical property of weld seam, and the double-shaft shoulder stirring-head shaft shoulder chucking power avoiding traditional structure is excessive and make to produce a large amount of overlaps and burr in welding process.Both improve car body assembled after total quality, greatly reduce again and repair weld defect man-hour of consuming, significantly reduce manufacturing cost, the go abroad world of marching toward of high ferro is significant.

Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 2:
The self adaptation bilateral dead axle shoulder stirring-head that the utility model provides is on the mixing needle 2 of stirring-head main body 1 one end, be socketed with the shaft shoulder 3 and the lower shaft shoulder 4, the rear end of wherein going up the shaft shoulder 3 is connected with thrust ball bearing 5, the front end of the lower shaft shoulder 4 is connected with deep groove ball bearing 6, be provided with elastomeric element 7 between the lower shaft shoulder 4 and deep groove ball bearing 6, deep groove ball bearing 6, elastomeric element 7, the lower shaft shoulder 4, the upper shaft shoulder 3 and thrust ball bearing 5 are serially connected on mixing needle 2 successively by a chassis 8 is fixing.
Stirring-head main body 1 and mixing needle 2 as a whole, adopt H13 steel to do.
