Abstract
A kind of arc welded tube structure, comprise a hollow arc welded tube and a hollow sleeve, sleeve upper end is arranged in arc welded tube, and the periphery wall of sleeve upper end matches with the inner circle wall of arc welded tube, adopt laser bonding between cannula tip and arc inner wall of welded pipe, its lower end periphery wall is provided with outside thread.A kind of arc welded tube structure that the utility model provides, the upper end of its sleeve pipe to be arranged in arc welded tube and to mate with arc shrouds, laser bonding is adopted between cannula tip and arc inner wall of welded pipe, the weld of arc welded tube can be made to be out of shape, and the smooth outer surface of the arc welded tube of weld, avoid polishing, save manpower and materials, reduce cost of production, improve manufacturing efficiency, the beautiful shape of arc welded tube can not be affected; Its lower end periphery wall is provided with outside thread, and outside thread can be spirally connected with miscellaneous part, removes and installs conveniently, is convenient for changing arc welded tube, avoids destructive dismounting arc welded tube and parts interconnective with arc welded tube.
Description
Technical field
The utility model relates to a kind of arc welded tube structure.
Background technique
At present, due to the particularity of arc welded tube profile, arc welded tube is when being connected with miscellaneous part, be all adopt welding Placement, but arc welded tube and miscellaneous part welding after weld surface roughness, need the surface finish of weld, just can make weld beautiful shape, but polishing weld is not only time-consuming but also require great effort, cost of labor is large, and efficiency is low; And, destructive dismounting can only be adopted when arc welded tube changed by needs, also have infringement to the miscellaneous part welded with it.
Model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of weld smooth outer surface, does not need the arc welded tube structure of polishing.
The utility model realizes like this, a kind of arc welded tube structure, comprise a hollow arc welded tube and a hollow sleeve, described sleeve upper end is arranged in described arc welded tube, the periphery wall of described sleeve upper end matches with the inner circle wall of described arc welded tube, adopt laser bonding between described cannula tip and described arc inner wall of welded pipe, described its lower end periphery wall is provided with outside thread.
The arc welded tube structure that the utility model provides, the upper end of its sleeve pipe to be arranged in arc welded tube and to mate with arc shrouds, weld between sleeve upper end top with arc inner wall of welded pipe, adopt laser bonding in arc welded tube inside, the smooth outer surface of the arc welded tube of weld, avoids polishing, save manpower and materials, reduce cost of production, improve manufacturing efficiency, also do not affect the beautiful shape of arc welded tube; Its lower end periphery wall is provided with outside thread, and outside thread can be spirally connected with miscellaneous part, removes and installs conveniently, is convenient for changing arc welded tube, avoids destructive dismounting arc welded tube and parts interconnective with arc welded tube.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram of the arc pipe welding mechanism that the utility model provides;
Fig. 2 is A place enlarged view in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
As depicted in figs. 1 and 2, a kind of arc welded tube structure that the utility model embodiment provides, comprise hollow arc welded tube 1 and a hollow sleeve 2, sleeve pipe 2 upper end is arranged in arc welded tube 1, the periphery wall of sleeve pipe 2 upper end matches with the inner circle wall of arc welded tube 1, adopt laser bonding between sleeve pipe 2 top and arc welded tube 1 inwall, sleeve pipe 2 lower end periphery wall is provided with outside thread 21.
The arc welded tube structure that the utility model provides, the upper end of its sleeve pipe 2 to be arranged in arc welded tube 1 and to mate with arc shrouds 1, because sleeve pipe 2 is hollow structure, therefore, laser welding system (not shown) can in threading 2, and laser bonding is carried out between sleeve pipe 2 top and arc welded tube 1 inwall, adopt the mode of laser bonding, the weld 3 of arc welded tube 1 can be made to be out of shape, and the smooth outer surface of the arc welded tube 1 of weld, avoid polishing, save manpower and materials, reduce cost of production, improve manufacturing efficiency, the beautiful shape of arc welded tube 1 can not be affected, sleeve pipe 2 lower end periphery wall is provided with outside thread 21, and outside thread 21 can be spirally connected with miscellaneous part, removes and installs conveniently, is convenient for changing arc welded tube 1, avoids destructive dismounting arc welded tube 1 and parts interconnective with arc welded tube 1.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
