Description
Technical field
The utility model relates to a kind of connection components, belong to engine exhaust system technical field.
Background technique
In recent years, target for energy-saving and emission-reduction has all been formulated in the multiple countries and regions in the world, and it is riding that China also clearly arrives the year two thousand twenty
Vehicle new car average fuel consumption reaches 5L/100km, and the pressure of energy-saving and emission-reduction is larger.In current many energy-saving and emission-reduction modes,
Automotive light weight technology is to be easiest to realization, the relatively large mode of potentiality.For riding gasoline car, every reduction 100kg can at most be saved
Oily 0.39L/100km.
So-called automotive light weight technology refers to and is guaranteeing that every important indicator such as automotive safety all meets country and professional standard is wanted
In the case where asking, in order to increase the utilization efficiency of the energy, make that its is more energy saving, safety, by using various advanced technologies or
Special material mitigates the process of car mass as much as possible.In the above context, automobile vendor is to the light-weighted requirement of components
It increases year by year.
The components of automobile exhaust system mostly use stainless steel material, realize that the most effective means of its lightweight are maximum limits
The wall thickness of the reduction material of degree.But while material wall thickness reduces, increase the difficulty of welding.In the relatively thin situation of base material wall thickness
Under, if welding current is big when welding, it is easy to base material burn-through；If welding current is small, base material fusion penetration is small, and welding is strong
It spends low, influences product quality.So gap is smaller for the welded connecting of thin-wall part, be more conducive to improve welding quality.
Common welding connecting mode mainly has the double-deck base material welding and three layers of base material welding, wherein three layers of base material welding
When, common mode is to snap into two layers of base material on bottom base material, certain gap (weld seam) is kept among two layers of base material, really
Welding arc can fuse together three layers of base material when protecting welding.Base material wall thickness is thinner, intermediate space (weld seam) require it is smaller and
Gap required precision is higher.To ensure the requirement, a salient point is designed generally on flange, plays the role of axial limiting.
It please join shown in Fig. 1 to Fig. 4, existing connection component 100 ' includes the first connecting tube 1 ', is socketed in first company
It the second connecting tube 2 ' on adapter tube 1 ' and is socketed in first connecting tube 1 ' and has between second connecting tube 2 '
There is the flange 3 ' in gap 20 '.First connecting tube 1 ', the second connecting tube 2 ' and flange 3 ' are referred to as " base material ".It is described
Flange 3 ' is equipped with the salient point 31 ' being located in gap 20 ', to play the role of adjusting gap 20 '.
However, being further thinned with wall thickness, the requirement to the radial clearance between three layers of base material is increased therewith, but former
The salient point 31 ' come only plays the position-limiting action of circumferential and axial, is unable to satisfy radial limit and requires.The way that industry uses is usual
Be control three layers of base material machining accuracy, thus come be the problem of controlling radial clearance, but thus bring difficulty of processing increase, report
Useless rate is higher, and processing cost is high.

To achieve the above objectives, the present invention adopts the following technical solutions: a kind of connection component comprising the first connection
It the second connecting tube for manage, being socketed in first connecting tube and is socketed in first connecting tube and connects with described second
There is the flange in gap, the flange is equipped with the spacing block set being located in the gap, and the spacing block set includes between adapter tube
Along it is axial with second connecting tube leans first compress face and be radially pressed against each other with first connecting tube the
Two compress face.
As the further improved technical solution of the utility model, the spacing block set and the flange are integrally formed.
As the further improved technical solution of the utility model, the spacing block set and the flange are non-coplanar.
As the further improved technical solution of the utility model, the spacing block set is along described in the radially protruding second
Connecting tube.
As the further improved technical solution of the utility model, the spacing block set is several.
As the further improved technical solution of the utility model, the spacing block set is evenly distributed on the week of the flange
Upwards.
As the further improved technical solution of the utility model, first connecting tube, second connecting tube and
The flange is made of stainless steel material.
As the further improved technical solution of the utility model, first connecting tube, second connecting tube and
The flange with a thickness of 0.8 ± 0.2 millimeter.
Welding material is filled as the further improved technical solution of the utility model, in the gap to by described the
One connecting tube, second connecting tube and the flange connect.
As the further improved technical solution of the utility model, the connection component includes partition, and the partition is equipped with
Mounting hole, the flange are located on the partition and are centered around around the mounting hole.
Compared to the prior art, the spacing block set of the utility model includes leaning along axial with second connecting tube
First compress face and be radially pressed against each other with first connecting tube second compress face, so set, can play simultaneously
The axial position-limiting action with radial direction.
