Abstract
The utility model discloses a connecting base applicable to welding among round parts of a bogie, and aims at solving the problem that welding implement among the round parts of the bogie is difficult. The connecting base comprises a connecting base body, wherein a cylinder-shaped part is arranged at one end of the connecting base body, and a flange which extends along the axis direction of the cylinder-shaped part is arranged on the end face of the cylinder-shaped part. The distance between the inner wall and the outer wall of the flange is 2mm-3mm, and the extending length along the axis direction is 4mm-5mm. The structure of the flange effectively has the functions of a welding cushion board and welding locating, special tools and welding cushion boards are not required, production period is shortened, and cost is reduced.
Description
Technical field
The utility model relates to a kind of Connection Block, is specially a kind of Connection Block of welding between the bogie truck central portion of being applicable to.
Background technology
Welding in the bogie truck 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 position of weld.
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 structure 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 attaching parts, 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 right alignment between attaching parts is difficult for guaranteeing, the frock manufacturing cost is higher, the cycle is longer, and recycling rate of waterused is not high.
The utility model content
For the problem of welding performance difficulty between the bogie truck central portion, the utility model aims to provide a kind of Connection Block of welding between the bogie truck central portion of being applicable to, and this Connection Block has flange, can effectively solve the Welding Problems between circular configuration in the bogie truck design.
To achieve these goals, the technical scheme that adopts of the utility model is:
A kind of Connection Block of welding between the bogie truck central portion of being applicable to, comprise the connection pedestal, its constructional 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 utility model has the feature that wall thickness is thinner, length is shorter.
Below be the technical scheme of further improvement of the utility model:
As a kind of version, when guaranteeing welding and the stable connection of bogie truck 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 thinner thickness, the shorter feature of 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, back 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 utility model 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 utility model also can increase face of weld greatly when welding when having the backing plate effect concurrently, improved weld strength.Compared with prior art, the beneficial effects of the utility model are:
1) flanged structure of the present utility model 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 utility model, 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 utility model 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 utility model 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 utility model is simple, connection is reliable and weight is lighter, relatively is applicable to the guideway vehicle of lightweight, high speed development.
Below in conjunction with drawings and Examples the utility model is further elaborated.
