To achieve these goals, the utility model uses following technical scheme：It is a kind of for weld-ring pre-coated soldering flux
Fixture, including：
One hook housing, and the hook on the hook housing top is arranged at,
The hook housing is cuboid, and the side face of the hook housing is evenly arranged with several and needs pre-coated soldering flux to hang
Circular or square weld-ring crotch；
The crotch stretches out from the side face of the hook housing, includes successively：Section of stretching out, vertical section, horizontal segment and inclination
Section.
Preferably, the hook housing is the cuboid of one of stainless steel, copper, copper alloy, aluminium, aluminum alloy materials.
Preferably, the hook is the silk material or sheet material of one of stainless steel, copper, copper alloy, aluminium, aluminium alloy.
Preferably, the crotch is the silk material of one of stainless steel, copper, copper alloy.
Preferably, the diameter of the crotch is between the 1/3 to 1/2 of preforming weld-ring internal diameter.
Preferably, the level interval of two adjacent crotches be square frame-shaped weld-ring longest edge length 1/3 to 1/2 it
Between, or between 2 times to 3 times of circular weld-ring external diameter；
The vertical spacing of two adjacent crotches is between 1.5 times to 2 times of square frame-shaped weld-ring longest edge length, or
Between 2 times to 3 times of circular weld-ring external diameter.
Preferably, between the angle of the horizontal segment of the crotch and the tilting section is 90 ° to 135 °.
The utility model using crotch due to supporting preforming weld-ring structure, and preforming weld-ring can be suspended on hook housing, in advance
Only several contact points are molded between weld-ring and hook housing, avoid preforming weld-ring from air-drying rear and fixture large area adhesion, easily
The preforming weld-ring of pre-coated soldering flux is taken out from fixture, ensure that the coating uniformity on preforming weld-ring two sides, avoid viscous
Preforming weld-ring deformation caused by even.Meanwhile the structure of crotch is applied to circular weld-ring, and square weld-ring.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of crotch shown in Fig. 1.
In figure, 1- hook housings；2- crotches；3- is linked up with；21- section of stretching out；22- vertical sections；23- horizontal segments；24- tilting sections.
Embodiment
Such scheme is described further below in conjunction with specific embodiment.It should be understood that these embodiments are to be used to illustrate
The utility model rather than limitation the scope of the utility model.The implementation condition used in embodiment can be according to specific producer
Condition does further adjustment, and unreceipted implementation condition is usually the condition in normal experiment.
As shown in figure 1, a kind of fixture for weld-ring pre-coated soldering flux of the utility model,
Including：Hook housing 1, crotch 2 and hook 3.
Above-mentioned hook housing 1 is the flat board of rectangle or square, and hook 3, the two sides of flat board are fixedly installed at the top of flat board
It is fixedly installed some crotches 2 of regular array.The material of above-mentioned hook housing 1 can be selected as stainless steel, copper, copper alloy, aluminium, aluminium
Alloy etc. not with flux reaction and with certain structural strength material.Air vent can be set on the flat board of above-mentioned hook housing 1,
Auxiliary air-dries weld-ring.
The material of above-mentioned hook 3 can select have certain structural strength for stainless steel, copper, copper alloy, aluminium, aluminium alloy etc.
Material, as long as can hang in supporting walls or support beam, facilitate pre-coated soldering flux and preforming weld-ring to air-dry.
As shown in Fig. 2 the material of above-mentioned crotch 2 is preferably copper wire, its structure can be divided into four sections：
First paragraph is section of stretching out 21, is attached with the main body of hook housing 1 and prevents preforming weld-ring and the plate face of hook housing 1 connects
Touch；
Second segment is vertical section 22；
3rd section is horizontal segment 23, preforming weld-ring main support in horizontal segment 22, pre-coated soldering flux, contact position compared with
It is small, adhesion between preforming weld-ring and fixture；
4th section is tilting section 24, prevents preforming weld-ring from sliding.
Above-mentioned crotch 2 can be replaced with materials such as stainless steel, copper alloys.
In order to avoid the touching between preforming weld-ring and crotch 2, preferably coating effect, the silk of above-mentioned crotch 2 are obtained
Material diameter is preferably between the 1/3 to 1/2 of preforming weld-ring internal diameter.
Support preforming weld-ring to be easy to pick and place in order to stable, and reduce the support between preforming weld-ring and crotch 2
Quantity, preferably：
The level interval of above-mentioned crotch 2 hang it is preforming weldering frame when, be weld frame longest edge length 1/3 to 1/2 between；
It is between 2 times to 3 times of weld-ring external diameter when hanging preforming weld-ring；
The vertical spacing of above-mentioned crotch 2 when hanging preforming weldering frame, be weld 1.5 times to 2 times of frame longest edge length it
Between；It is between 2 times to 3 times of weld-ring external diameter when hanging preforming weld-ring；
More than crotch 2 arrange spacing, it is ensured that preforming weld-ring horizontally suspends and is easy to pick and place.
Between the horizontal segment 23 of above-mentioned crotch 2 and the angle of tilting section 24 are 90 ° to 135 °, it can be prevented in dip coating process
The landing of preforming weld-ring.
Because hook housing 1 of the present utility model uses external silk material supporting construction, preforming weld-ring can be hung on crotch 2,
The contact surface very little of preforming weld-ring and fixture.After scaling powder is coated, the preforming surface of weld-ring two and the equal adhesion of fixture, wind
It is dry consistent, after preforming weld-ring surface welding-assistant air-dries, easily the preforming weld-ring of pre-coated soldering flux is taken from fixture
Go out.
The utility model is applicable not only to weld-ring, applies also for welding other hollow weld tabs such as frame.
In addition to above example, hook housing 1 of the present utility model can also use cuboid or square, in cuboid or just
Crotch 2 is set on the side face of cube.
Finally it should be noted that above example is merely to illustrate the technical solution of the utility model rather than to this practicality
The limitation of novel protected scope.Although being explained in detail with reference to preferred embodiment to the utility model, the common skill of this area
Art personnel should be appreciated that and the technical solution of the utility model can be modified or equivalent substitution, without departing from this practicality
The spirit and scope of new technique scheme.
