The present invention relates to Cool-water Machine for Industry technical field, in particular to a kind of cooling-water machine brazing jig and its soldering sideMethod.
Background technique
As countries in the world propose the release of traditional energy automobile off-time table, new-energy automobile technology obtains in the whole worldThe development advanced by leaps and bounds, people have to while solving the problems, such as new-energy automobile course continuation mileage facing to the use pair of air-conditioningThe huge consumption of battery, comes that the heat management problems of battery are more prominent therefrom, a kind of completely new in battery thermal management schemeProducts C hiller (Cool-water Machine for Industry) comes into being with the development of the times, it can play constant temperature to battery and keep energy consumptionMinimum consumption and the comfort that air-conditioning can be maintained, the working condition that the birth of a new product must have, Chiller'sComplexity causes the difficulty of its production process to increase, and soldering efficiency is lower in production process, and product qualification rate is to be improved.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of cooling-water machine soldering folderTool and its method for welding, to achieve the purpose that improve soldering efficiency, improve product qualification rate.
In order to solve the above technical problems, the technical scheme is that a kind of cooling-water machine brazing jig, including it is to be weldedPart, the part to be welded include cooling-water machine lamination, flange, bottom plate, and the cooling-water machine lamination is arranged on bottom plate, the methodOrchid is arranged on cooling-water machine upper end lamination face, and the brazing jig further includes fixed mechanism, and the flange upper surface is pressed withWhole pressing plate, the whole pressing plate upper surface are connect by elastic mechanism with fixed structure.
The fixed mechanism includes support plate, balance plate, position limit arm, and the support plate is supported under the bottom plateThe top of whole pressing plate is arranged in side, the balance plate, is connected between the balance plate and support plate by position limit arm.
The position limit arm is two, is connected to the both ends of balance plate.
The both ends of the balance plate are respectively equipped with groove, and the lower end of the position limit arm is connect with support plate, position limit armUpper end protrude into the groove limit, the upper end of the position limit arm is equipped with the card slot being connected on balance plate.
The elastic mechanism includes spring, and the whole pressing plate upper surface is connected by spring and the balance plateIt connects.
The spring is two.
A method of using cooling-water machine with brazing jig be brazed, the method the following steps are included:
A) cooling-water machine lamination is arranged on bottom plate, flange is arranged on cooling-water machine upper end lamination face, cooling-water machine lamination, methodBlue, bottom plate is assembled into part to be welded；
B) support plate is placed on to the lower section of part to be welded；
C) whole pressing plate is placed in the top of part to be welded, whole pressing plate upper surface is connect by spring with balance plate；
D) position limit arm lower end is connect with support plate, the upper end of position limit arm is connected to the end of balance plate, two ends of balance platePosition limit arm is loaded onto respectively, and part to be welded is brazed.
The present invention using the above structure and method, has the advantage that 1, spring makes brazing jig have retractility, meetsPart to be welded carries out the requirement of free wxpansion during the brazing process, although balance plate makes flange and cooling-water machine lamination not in a plane energyUniform stressed, the requirement of qualification rate when position limit arm can satisfy part to be welded weld size and soldering；The present invention is efficient, at low costIt is honest and clean, the processing is simple, can significantly improve product soldering when qualification rate, reduce labor intensity of workers.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments；

Specific embodiment
A kind of cooling-water machine brazing jig as shown in Figure 1, including part to be welded, part to be welded include cooling-water machine lamination 8, flange 7,Bottom plate 2, cooling-water machine lamination 8 are arranged on a base plate 2, and flange 7 is arranged on 8 upper surface of cooling-water machine lamination, and brazing jig further includesFixed mechanism, 7 upper surface of flange are pressed with whole pressing plate 6, and whole 6 upper surface of pressing plate is connect by elastic mechanism with fixed structure.
Fixed mechanism includes support plate 1, balance plate 4, position limit arm 3, and support plate 1 is supported on 2 lower section of bottom plate, and balance plate 4 is setIt sets in the top of whole pressing plate 6, is connected between balance plate 4 and support plate 1 by position limit arm 3.Position limit arm 3 is two, is connected respectivelyIt connects at the both ends of balance plate 4.The both ends of balance plate 4 are respectively equipped with groove, and the lower end of position limit arm 3 is connect with support plate 1, position limit armGroove limit is protruded into 3 upper end, and the upper end of position limit arm 3 is equipped with the card slot being connected on balance plate 4.Elastic mechanism includes spring 5,Whole 6 upper surface of pressing plate is connect by spring 5 with balance plate 4.Spring 5 is two.
A method of using cooling-water machine with brazing jig be brazed, method the following steps are included:
A) on a base plate 2 by the setting of cooling-water machine lamination 8, flange 7 is arranged on 8 upper surface of cooling-water machine lamination, and cooling-water machine is foldedPiece 8, flange 7, bottom plate 2 are assembled into part to be welded；
B) support plate 1 is placed on to the lower section of part to be welded；
C) whole pressing plate 6 is placed in the top of part to be welded, whole to compress to part to be welded, whole 6 upper surface of pressing plate is logicalSpring 5 is crossed to connect with balance plate 4；Spring 5 makes brazing jig have retractility, meets part to be welded and carries out free wxpansion during the brazing processRequirement, although balance plate 4 make flange 7 and cooling-water machine lamination 8 not plane can uniform stressed, position limit arm 2 can expireThe requirement of qualification rate when sufficient part to be welded weld size and soldering.
D) 3 lower end of position limit arm is connect with support plate 1, the upper end of position limit arm 3 is connected to the end of balance plate 4, balance plate 4Position limit arm 3 is loaded at both ends respectively, is brazed to part to be welded.The present invention is efficient, low in cost, the processing is simple, can be largelyImprove product soldering when qualification rate, reduce labor intensity of workers.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid wayLimitation, as long as using the various improvement that technical solution of the present invention carries out, or not improved directly apply to other occasions, it is within the scope of the present invention.
