Abstract
The invention discloses a kind of stacked oil cooler vacuum brazing clamps, belong to vacuum brazing clamp；It is intended to provide a kind of vacuum brazing clamp that can effectively improve solder yield.It includes positioning component and holds down assembly；The positioning component is made of the rest pad (7) and positioning pin (8), three ladder-like support shafts (5) being fixed on lower channel steel (6) surface for being fixed on lower channel steel (6) surface, three support shaft (5) distributions triangular in shape；It is described hold down assembly by the upper channel steel (1) being supported on three support rods (5), the stud (12) for being upward through channel steel on this and being connect respectively with nut, the pressing plate (9) for being fixed on each stud (12) lower end, between the pressing plate and upper channel steel (1) and the spring (2) that is separately mounted on each stud (12) is constituted.It is the configuration of the present invention is simple, easy to operate, it is a kind of vacuum brazing clamp for oil cooler.
Description
Technical field
The present invention relates to a kind of oil cooler oil cooler welding clamp more particularly to a kind of stacked oil cooler vacuum brazing folders
Tool；Belong to vacuum brazing clamp.
Background technique
Oil cooler is a kind of a kind of radiator for accelerating lubricating oil heat dissipation, making its holding lower temperature；Mainly by bottom plate,
Radiating core and cover board etc. are constituted, and radiating core is mainly made of gusset and fin.After being assembled with upper-part usually all
Clamping is carried out using fixture, then be re-fed into vacuum brazing furnace and welded.In the welding process, due to gusset, fin
Equal components have certain elasticity, and brazing process can generate thermal expansion；Just it will appear between gusset, between gusset and fin
Gap causes weld seam the discontinuous defect such as gap, stomata occur, so as to cause leakage.In addition, each part is in brazing process
Hot mastication state, and current fixture does not have limit function；Oil cooler is caused to be constantly in pressured state in welding process,
Product height dimension is seriously partially ultralow after soldering, is unable to satisfy design requirement.
Summary of the invention
In order to overcome defect existing in the prior art, the present invention is intended to provide one kind can effectively improve welding qualification
Rate, and the stacked oil cooler vacuum brazing clamp that structure is simple and convenient to operate.
To achieve the goals above, the invention adopts the following technical scheme: it includes positioning component and holds down assembly；It is described
Positioning component is by being fixed on the rest pad and positioning pin, three ladder-like support shafts for being fixed on lower channel steel surface on lower channel steel surface
It constitutes, three support shaft distributions triangular in shape；It is described hold down assembly by be supported on three support rods upper channel steel, be upward through
Channel steel and the stud being connect respectively with nut, the pressing plate for being fixed on each stud lower end on this, between the pressing plate and upper channel steel
And it is separately mounted to the composition of the spring on each stud.
Upper channel steel passes through the bushing being fixed thereon and is connected respectively with each support rod；Left handle is fixed on upper channel steel
And right handles.
Compared with the prior art, the present invention is by adopting the above-described technical solution, realize radiating core using positioning component is determined
Body positions and guarantees that its is smooth, and Product jointing is thus prevented to be deformed distortion in the process.Since pressing plate makes in conjunction with spring
With, therefore can press and clamp to oil cooler in brazing process, the requirement being brazed to fit clearance is met, is substantially increased
Product is brazed qualification rate.Third can play support limit to upper component due to using the support shaft of step structure
Effect avoids product super in short transverse to can guarantee that radiating core no longer applies pressure to it in cooling meat rear fender
Poor (height dimension is relatively low).
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the structural schematic diagram of stacked oil cooler；
Fig. 4 is the top view of Fig. 3.
In figure: upper channel steel 1, spring 2, right handles 3, bushing 4, support shaft 5, lower channel steel 6, rest pad 7, positioning pin 8, pressing plate
9, left handle 10, screw 11, stud 12, workpiece 13.
Specific embodiment
The invention will be further described with specific embodiment with reference to the accompanying drawing:
As shown in figures 1-4, the present invention includes positioning component and holds down assembly.
The positioning component is by being fixed on the rest pad 7 on lower 6 surface of channel steel and positioning pin 8, being fixed on lower 6 surface of channel steel
The support shaft 5 of three step structures is constituted, three distributions triangular in shape of support shaft 5.
It is described hold down assembly by be supported on three support rods 5 upper channel steel 1, be upward through on this channel steel and respectively with spiral shell
The stud 12 of female (not indicated in figure) connection, the pressing plate 9 for being fixed on each 12 lower end of stud, be located at the pressing plate and upper channel steel 1 it
Between and the spring 2 that is separately mounted on each stud 12 constitute.
In order to guarantee upper channel steel 1 can level move up and down, upper channel steel 1 passes through the bushing 4 that is fixed thereon and each support
Bar 5 respectively corresponds mating connection.
For ease of operation, there is the left handle 10 fixed by screw 11 in the left side close to upper channel steel 1, close to upper slot
There are the right handles 3 fixed by screw 11 on the right side of steel 1.
In use, by the stacked oil cooler of workpiece 13() radiating core lie against on rest pad 7, and positioning pin 8 is inserted
Enter in the hole of positioning convex platform and (do not indicated in figure), then will entirely upper assembly set be led in three support shafts 5 by bushing 4
The pressure of each spring 2 of nut adjustment is crossed, guarantees that pressing plate 9 is contacted with pressing force appropriate with workpiece 13.
