Description
Technical field
The utility model belongs to body for mass transit vehicles structure member field, is specifically related to a kind of friction stir welding sleeper beam structure for car body and section bar I thereof and section bar II.
Background technology
The structure that the sleeper beam of current aluminum-alloy all-welded vehicle body mostly is adaptation arc welding and designs, adding one piece of sheet material welding by two block-type materials forms, and assembly precision is low, and must increase welding bearing rib for controlling welding deformation.Adopt this structure to need many weld seams, during welding adopt multi-pass welding, its welding capacity is large, welding stress is large, welding deformation is large and be difficult to control, cause production efficiency low, assembly precision is low.Further, because assembly precision is low, be out of shape large when adding welding, so workload is large in later stage leveling process.
In order to make in sleeper beam welding process, improve assembly precision, reduce welding deformation, the mode of friction stir welding can be adopted to carry out the welding of sleeper beam structure, but still do not have a kind of sleeper beam structure can be applicable to the needs of this welding manner of friction stir welding at present, existing sleeper beam structure carries out friction stir welding often causes yield rate low, and intensity etc. do not reach requirement.
Utility model content
For the problems referred to above, it is high that the utility model aims to provide a kind of assembly precision, can be applicable to the sleeper beam structure of friction stir welding and section bar I thereof and section bar II.
The technical scheme that the utility model is dealt with problems is: a kind of friction stir welding sleeper beam structure for car body, comprise section bar I and section bar II, described section bar II comprises upper gusset and the lower web plate of horizontally set, upper gusset is parallel with lower web plate, the right-hand member of upper and lower gusset is vertically provided with right side wall, right side wall upper end and upper link of boards, lower end is connected with lower web plate, and upper gusset is vertical with between lower web plate is provided with vertical supporting gusset.
Lower web plate on the left of vertical supporting gusset stretches out obliquely the welding bearing rib supporting gusset when being provided with for welding, the other end of this welding bearing rib is fixedly connected with upper gusset.
The upper gusset of vertical supporting gusset and section bar II, lower web plate, right side wall surround cavity.
The right side wall upper level of described section bar II is provided with floor overlap joint gusset, and right side wall is provided with bogie with the intersection horizontal-extending of lower web plate and is connected gusset.
On section bar II, the left end of gusset and lower web plate is equipped with ladder boss, is vertically provided with vertical intermediate supports gusset between two ladder boss.
Described section bar I is connected gusset formed along intermediate supports gusset symmetry by the upper gusset of section bar II, lower web plate, right side wall, welding bearing rib, vertical supporting gusset, floor overlap joint gusset, bogie, and the right-hand member of the upper gusset of section bar I and lower web plate is respectively equipped with extension, ladder boss on the upper gusset of this extension and section bar II and lower web plate overlaps, after overlap joint, on gusset and section bar I, the upper surface of gusset keeps same level height on section bar II, and the lower surface of section bar II lower web plate and section bar I lower web plate remains on same plane.
The seam formed after the upper gusset of section bar II and the upper gusset of section bar I overlap adopts friction stir welding to weld, and the seam formed after the lower web plate of section bar II and the lower web plate of section bar I overlap adopts friction stir welding to weld.
Preferably, the welding bearing rib of section bar II is arranged on the angle, right angle, left side of lower web plate and vertical supporting gusset.
In such scheme, in the cavity that the upper gusset of vertical supporting gusset and section bar II, lower web plate, right side wall surround, be provided with reinforcement gusset, be also provided with in section bar I and the reinforcement gusset of this reinforcement gusset along intermediate supports gusset symmetry.Described reinforcement gusset is the sleeper beam gusset stretching out setting in the angle, right angle, right side of lower web plate and vertical supporting gusset obliquely, and at the skewed horizontal load gusset that the angle, right angle, right side of upper gusset and vertical supporting gusset is stretched out obliquely; Described skewed horizontal load gusset is crossing on section bar II right side wall with sleeper beam gusset, and is fixedly connected with in three intersection.Strengthen the rigidity that gusset can strengthen sleeper beam in die cavity, in balance, lower cantalever gusset is stressed.
Add man-hour, first friction stir welding is carried out to the seam formed after upper gusset overlap joint, and then overturn, because upper gusset weld seam has made two block-type materials become overall, enough rigidity can be provided, meet the friction stir welding rigidity requirement of sleeper beam lower web plate.To the seam welding formed after lower web plate overlap joint, complete the connection of workpiece.Described floor overlap joint gusset is used for installation or the connection of floor panel structure, and described bogie connects gusset and bogie is installed.
Remarkable result of the present utility model is: sleeper beam structure overlap by section bar II and section bar I and forms, and the two phase mutual position limits, and makes two section bars can self-regulation, the unfitness of butt joint of control short transverse, meets the requirement of friction stir welding to flatness and linearity;
When friction stir welding is carried out to gusset on sleeper beam, bottom has two block welding bearing ribs and intermediate supports gusset to provide support, ensure that being welded with enough rigidity supports, reduce the impact of friction stir welding shaft shoulder pressure welding quality and distortion, thus be conducive to obtaining high-quality weld seam and less distortion;
The sleeper beam of this kind of structure only needs two weld seams to complete welding, and weld interval shortens greatly, and production efficiency is high, and structural strength is high and do not need other auxiliary gripper shoe of extra soldered in welding process.Total is simple, and wall thickness is thin, lightweight.
In addition, because this kind of sleeper beam structure assembly precision is high, welding deformation is little, so workload is little in later stage leveling process.
In a word, sleeper beam structure of the present utility model is applicable to agitating friction welding more.
