Abstract
The utility model discloses a kind of condenser soldering fixture, including fixture base, two groups of elasticity clamping mechanisms of longitudinally spaced setting, every group of elasticity clamping mechanism include the collet of at least two laterally spaced settings in fixture base.The utility model fixture steps up condenser product using collet, collet heats up with core in welding expands and compresses or shrink and stretch with core cooling, the elastic spacing to the header of product is realized, to avoid header deformation caused by due to limiting condenser collecting pipe using rigid dieback and bound edge can not be with the defect problem of header soldering.
Description
Technical field
The utility model relates to air conditioning for automobiles production field, especially a kind of automotive air-conditioning condenser brazing jig.
Background technique
Existing condenser soldering fixture is all made of stainless steel plate rigid top and extremely limits, and stainless steel plate is to condenser
Clamping force is uncontrollable in brazing process.
Since condenser collecting pipe material is aluminum component, the expansion of brazing process high temperature softens, and uses stainless steel plate rigidity
Dieback limit, easily causes header to deform, and then cause scrap of the product；In addition, extremely limited using stainless steel plate rigid top,
Condenser bound edge easily occurs can not be with header soldering defect.
Summary of the invention
Goal of the invention: the utility model aim is to provide a kind of automotive air-conditioning condenser brazing jig, to avoid because right
Condenser collecting pipe using rigid dieback limit caused by header deformation and bound edge can not be with header soldering defect problem.
To achieve the goals above, the utility model uses a kind of the following technical solution: condenser soldering fixture, packet
Fixture base is included, two groups of elasticity clamping mechanisms of longitudinally spaced setting, every group of elasticity clamping mechanism include in the fixture base
The collet of at least two laterally spaced settings.
Further, the collet includes high temperature resistant spring, limit loose piece sleeve, limit loose piece and positioning pin, institute
It states limit loose piece sleeve to be horizontally fixed in fixture base, limits the closed at one end of loose piece sleeve, limit the another of loose piece sleeve
End insertion limit loose piece, limit loose piece sleeve lateral wall are equipped with positioning pin, the bar shaped positioning pin of positioning pin insertion limit loose piece side
Slot, limit loose piece sleeve inner are equipped with high temperature resistant spring, and one end of high temperature resistant spring is resistance to against the closed end of limit loose piece sleeve
The other end of high temperature spring is against limit loose piece.
Further, every group of elasticity clamping mechanism includes two collets.
Further, the collet position of two groups of elasticity clamping mechanisms corresponds.
The utility model has the advantages that the utility model fixture steps up condenser product using collet, collet is with core in welding
Body heating expansion and compress or cool down with core and shrink and stretch, the elastic spacing to the header of product is realized, to avoid
Header deformation caused by due to being limited condenser collecting pipe using rigid dieback and bound edge can not be scarce with header soldering
The problem of falling into.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of collet；
In figure: 1- fixture base, 2- collet, 2-1- high temperature resistant spring, 2-2- limit loose piece sleeve, and 2-3- limit is lived
Block, 2-4- positioning pin, 2-5- bar shaped position cotter way.
Specific embodiment:
Further explanation is done to the utility model with reference to the accompanying drawing.
As shown in Figure 1, a kind of condenser soldering fixture of the utility model, including fixture base 1, the fixture base 1
Upper two groups of elasticity clamping mechanisms of longitudinally spaced setting, every group of elasticity clamping mechanism includes at least two laterally spaced settings
Collet 2.In the present embodiment, every group of elasticity clamping mechanism includes two collets 2 and two groups of elasticity step up machine
2 position of collet of structure corresponds.
As shown in Fig. 2, the collet 2 includes high temperature resistant spring 2-1, limit loose piece sleeve 2-2, limit loose piece 2-3
It is horizontally fixed in fixture base 1 with positioning pin 2-4, the limit loose piece sleeve 2-2, limits an end seal of loose piece sleeve 2-2
It closes, the other end insertion limit loose piece 2-3 of limit loose piece sleeve 2-2, limit loose piece sleeve 2-2 side wall is equipped with positioning pin 2-4, fixed
The bar shaped of the position pin 2-4 insertion limit side loose piece 2-3 positions cotter way 2-5, is equipped with high temperature resistant spring inside limit loose piece sleeve 2-2
One end of 2-1, high temperature resistant spring 2-1 against the closed end of limit loose piece sleeve 2-2, the other end of high temperature resistant spring 2-1 against
Limit loose piece 2-3.
The condenser soldering fixture working principle: condenser product group is placed in 1 top of fixture base after installing, pass through four
A collet 2 applies four elastic forces to the header of product, can change application by adjusting high temperature resistant spring 2-1 size
The size of power, in soldering, limit loose piece 2-3 heats up with condenser core to be expanded and shrinks or shrink and stretch with core cooling
The elastic spacing to the header of product is realized in exhibition.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
