Abstract
The invention discloses a connecting seat suitable for welding between circular parts of a bogie. In order to solve the problem that the welding between the circular parts of the bogie is difficult to implement, the connecting seat comprises a connecting seat body, wherein one end of the connecting seat body is provided with a cylindrical part; a flange which extends along the axis direction of the cylindrical part is formed on the end face of the cylindrical part; the distance between the inner wall and outer wall of the flange is 2 to 3mm; and the extension length of the flange along the axis direction is 4 to 5mm. According to the flange structure, the welding base plate function and the welding positioning function are effectively realized, a special fixture and a welding base plate are not required, the production period is shortened, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of Connection Block, be specially a kind of Connection Block of welding between the bogie central portion of being applicable to.
Background technology
Welding in the bogie design between central portion is common in the key part structure such as the welding, drawing pull bar of truck transom steel pipe and curb girder, has relatively high expectations in welding quality and welding position.
As shown in Figure 4, welding between traditional central portion is often inserted in the circular connected piece inner core by thicker long flange, thickness of flange is generally the wall thickness of circular connected component, and the length of flange is generally about the twice of circular connected component wall thickness, is about 20mm.The problem that this structure exists is as follows:
1, can not complete penetration between thicker flange and circle are connected, the weld seam anti-fatigue ability is not high;
2, long flange and circle are in contact with one another between being connected, and cause weld seam and flange and circular connected piece to act on simultaneously, and this is relatively to abstain from the structural design.
Therefore in engineering practice, the Connection Block of this thick long flange is also impracticable.
In view of above-mentioned problem with Connection Block existence of thick long flanged structure, this area has been given up this connecting base structure gradually, as shown in Figure 5, adopt at present ceramic backing or steel plate backing plate 6 to guarantee the welding quality of butt weld, but this structure also there are the following problems:
1, ceramic backing or steel plate backing plate 6 are difficult fixing with respect to the position between connector, and can occurring pad in the welding, to cooperate inhomogeneous, weld seam back to be shaped bad, reduced to a certain extent the weld seam anti-fatigue ability.
2, the axial location of 1 of central portion must the special frock of design, otherwise the axiality between connector is difficult for guaranteeing that the frock manufacturing cost is higher, the cycle is longer, and recycling rate of waterused is not high.
Summary of the invention
For the problem of welding performance difficulty between the bogie central portion, the present invention aims to provide a kind of Connection Block of welding between the bogie central portion of being applicable to, and this Connection Block has flange, can effectively solve the Welding Problems between circular configuration in the bogie design.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of Connection Block of welding between the bogie central portion of being applicable to, comprise the connection pedestal, its design feature is: an end of described connection pedestal has cylinder-like part, have a flange along the extension of cylinder-like part axis direction on the end face of this cylinder-like part, the distance L between described flange inner wall and the outer wall is 2mm～3mm.
Flange of the present invention has the feature that wall thickness is thinner, length is short.
Below be the technical scheme of further improvement of the present invention:
As a kind of version, when guaranteeing welding and the stable connection of bogie central portion to be welded reliable, it is circular that described flange preferably is, and this flange and cylinder-like part coaxial line.
Further, described flange is 4mm～5mm along the length that the cylinder-like part axis direction extends; Whole flange has the short feature of thinner thickness, length.
In order to guarantee to weld accurate positioning, reliable in quality, a part of length of described flange places in the cavity that is connected central portion when welding, and the outer wall of flange is close to the cavity inner wall that is connected central portion, thereby guarantees that the location is reliable; The other a part of length of flange is positioned at the attachment weld downside, serves as composition backing, and even weld, sealing run are shaped good, thereby guarantees reliable welding quality.
The bearing of trend of the internal face of described flange is parallel with the cylinder-like part axis direction, is one section arc transition between flange inner and Connection Block, makes transition of stress smoother, has improved the anti-fatigue ability of weld seam.
By said structure, flanged structure of the present invention effectively plays composition backing effect and welding positioning action, does not need special frock and composition backing, has shortened the production cycle, has reduced cost.
Flanged structure of the present invention also can increase solder side greatly when welding when having the backing plate effect concurrently, improved weld strength.Compared with prior art, the invention has the beneficial effects as follows:
1) flanged structure of the present invention effectively plays composition backing effect and welding positioning action, does not need special frock and composition backing, has shortened the production cycle, has reduced cost.
2) flanged structure thinner thickness of the present invention, length is shorter, welding stress is low after the welding, avoided traditional flanged structure be connected between between be in contact with one another and produced the phenomenon of locating.
3) flanged structure of the present invention cooperates evenly with the central portion inner face, efficiently solves composition backing and cooperates the difficult problems such as inhomogeneous, that the weld seam back shape is undesirable.
4) be one section arc transition between flanged structure inboard of the present invention and Connection Block, make between weld seam and Connection Block transition of stress smoother, improved the anti-fatigue ability of weld seam.
5) flanged structure of the present invention is simple, connection is reliable and weight is lighter, relatively is applicable to the rail vehicle of lightweight, high speed development.
The present invention is further elaborated below in conjunction with drawings and Examples.
