Joint structure, have many advantages, such as it is easy to process, reduce cost, productivity and qualification rate be provided.
The purpose of the present invention can be achieved through the following technical solutions:
It is a kind of for weld positioning joint structure, including the first hollow connector, first connector include according to
Upper clamping portion, transition part and the lower clamping portion of secondary connection, further include the second hollow connector, second connector includes phase
The sleeved part of connection and expanding unit, the upper clamping portion and pipeline are clamped, and the lower clamping portion is connect with product interface, the set
If portion is set on lower clamping portion, the setting of product interface peripherals is close in the expanding unit.
The end of the lower clamping portion forms the flaring with the riveting of product interface.
First connector is an integral structure.
Second connector is an integral structure.
The expanding unit is cyclic structure.
The internal diameter of the upper clamping portion is greater than the internal diameter of lower clamping portion.
The upper clamping portion, lower clamping portion and sleeved part are hollow cylindrical-shaped structure.
The upper clamping portion and pipeline weld.
The expanding unit and product interface peripherals weld.
Compared with prior art, the invention has the following advantages that
1) present invention is by being changed to two by original special-shaped overall structure to the related improvement on tradition connection header structure
Component: the first connector and the second connector, while fastening, process, produce it is more convenient.
2) sealed end of external pipeline can be connect without processing with inventive joint structure, without using sealing ring, side
Just the preparation of material.
3) inventive joint structure can be effectively reduced development cost, improve the productivity and qualification rate of product.
4) end of lower clamping portion forms the flaring with the riveting of product interface in the present invention, so that the first connector and product
Interface is tightly fastened, and upper clamping portion and pipeline welding and expanding unit are welded with product interface peripherals, and structure is reliable, service life
It is long.
5) it is widely used, the piping connection of radiator, intercooler and steam air heater suitable for full aluminium class etc. is practical.

Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to
Following embodiments.
As shown in Figures 2 and 3, a kind of joint structure for welding positioning includes the first connector 7 and the second connector
8, the first connector 7 is hollow integral structure, including sequentially connected upper clamping portion 9, transition part 10 and lower clamping portion 11,
Second connector 8 is hollow integral structure, and the second connector 8 includes the sleeved part 12 being connected and expanding unit 13, upper card
Socket part 9 and pipeline 1 are clamped, and lower clamping portion 11 is connect with product interface, and sleeved part 12 is set on lower clamping portion 11, expanding unit 13
It is close to the setting of product interface peripherals, upper clamping portion 9 is welded with pipeline 1, and expanding unit 13 and product interface peripherals weld, in which: under
