Faradic important component is transmitted in Welding, the quality of coil design is very big to heat effect.The shortcomings that presently, there are
Be sensing part (induction coil) interchangeability and adaptability it is poor, be unsuitable on some complex-shaped workpiece using etc..
In Generator Stator winding installation process, the weld quantity of stator winding can up to thousands of, weldering
Joint will not only have good electric conductivity, and vibration stress when still suffering from generator normal operation and powerful in short-term
Mechanical stress, welding quality require high, while because the construction period requires to complete hundreds of different parts within a certain period of time
Welding welding efficiency is also required.In addition because collector ring welding position is in diverse location, weld seam surrounding space size is each
Differ, existing induction coil does not adapt to the welding needs of collector ring in structure design, does not play induction brazing and is converging
Flow the advantage during boxing connects.Weld seam state observation when adjusting difficulty, welding before being welded such as collector ring between induction coil and workpiece
Difficult with filler, welding efficiency is low and induction coil is fragile, and the girth joint that confluxes of portion can not use existing induction coil.
Therefore, it is necessary to carry out technological improvement to existing induction coil according to air-cooled type generator collector ring welding engineering is actual completely.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is the provision of a kind of air-cooled type generator unit stator
Winding confluxes copper ring soldering induction coil, reasonable in design, simple in construction, meets that the heating welding requirements of the cylinder such as collector ring weldment is abundant
The advantages of playing induction brazing, adaptability of the increase induction coil in cylinder weldment, meets that air-cooled type generator collector ring is pacified
The welding of different parts needs in dress, suitable for promoting.
To achieve the above object, the utility model provides following technical scheme：
A kind of air-cooled type generator unit stator winding confluxes copper ring soldering induction coil, and corresponding with cylinder weldment, its feature exists
In：Including base, it is provided with base and induction coil is installed, the centre position of induction coil is used to observe weld seam and entered for one
The opening of row fill solder；The both sides of the induction coil are respectively arranged with magnetic conductor；The induction coil is by hollow design
Copper pipe made of, and logical coolant inside copper pipe.
As a kind of technical scheme of optimization, the induction coil uses single turn cambered design, and the surface of induction coil
Scribble insulating barrier.
As a kind of technical scheme of optimization, the end of the induction coil is cambered design, the radian of arc for 130 °-
180°。
As a kind of technical scheme of optimization, insulation board is provided with base, insulation board is arranged between induction coil.
By adopting the above-described technical solution, compared with prior art, the utility model is designed reasonably is simple in construction, it is full
The advantages of heating welding requirements of the cylinder such as sufficient collector ring weldment gives full play to induction brazing, increase induction coil is in cylinder weldment
Adaptability, meet air-cooled type generator collector ring installation in different parts welding needs, suitable for promote.
The utility model is described further with embodiment referring to the drawings.
Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of the utility model；
Fig. 2 is Fig. 1 overlooking the structure diagram.
Embodiment
Embodiment
As shown in Figure 1-2, a kind of air-cooled type generator unit stator winding confluxes copper ring soldering induction coil, with the phase of cylinder weldment 6
It is corresponding, including base 5, it is provided with base 5 and induction coil 2 is installed, the centre position of induction coil 2 is used to observe weldering for one
Seam and the opening 3 for carrying out fill solder.The both sides of the induction coil 2 are respectively arranged with magnetic conductor 1.The induction coil be by
Made of the copper pipe of hollow design, and logical coolant inside copper pipe.
The induction coil 2 uses single turn cambered design, and the surface of induction coil 2 scribbles insulating barrier.The line of induction
The end of circle is cambered design, and the radian of arc is 130 ° -180 °.Insulation board 4 is provided with base 5, insulation board 4 is arranged on sense
Answer between coil.
In the present embodiment, the monnolithic case of induction coil 2 is designed as semicircular arc, is made between the copper pipe of coil and reserves weldering
Seam observation and the opening of fill solder, meet the requirement of the cylinder such as collector ring weldment heating welding, give full play to induction brazing
Advantage, adaptability of the induction coil in cylinder weldment is added, meet different parts in the installation of air-cooled type generator collector ring
Welding need.
The induction coil 2 uses single turn cambered design, and radian between 130-180 degree, lead by the installation of induction coil both sides
Magnet 1.Induction coil surface insulation, coil inside lead to cooling water, induction coil can be moved along position while welding during use, according to remittance
Surrounding space situation is adjusted during the cylinder weldment installation such as stream ring, expands the adaptability of induction coil.Before welding, workpiece and sense
