Abstract
The utility model discloses an assembling clamp of a high-level plate-fin engine oil cooler, which comprises an assembling clamp base, wherein assembling height limit columns are mounted on two sides of the assembling clamp base; the upper end and the lower end of the assembling height limit column are provided with an upper welding clamp board and a lower welding clamp board; the lower welding clamp board is connected with the assembling clamp base; and the top face of the upper welding clamp board is provided with a lower pressing block. According to the utility model, an original assembling clamp is redesigned by the assembling clamp; an assembling fixture including a limit structure is customized by press-mounting principle according to the shape of a high-level engine oil cooler; therefore, engine oil cooler products are kept identically at an assembling height before a brazing procedure.
Description
Technical field
The utility model relates to a kind of high-level plate fin oil cooler assembling jig.
Background technology
Existing high-level plate fin oil cooler is made up of adpting flange, chip assembly, spacer ring and end core cushion block; The cooled wafer number of plies of high-level plate fin oil cooler product is usually more than 25 layers; Because the chip number of plies is more; Oil cooler oil cooler overall height dimension level after vacuum welding is uneven, wayward, is manufacturing the more common main difficult point problem of link.
Existing high-level plate fin oil cooler manufacturing technology must let product after soldering, reserve certain allowance; Revise to the specification requirement size after compressing through external force then; Wherein correction mainly is that the cooler through soldering is placed on the hydraulic press more than 100 tons to product through external force; Through hydraulic press pressure the cooler height overall is compacted to the technical pattern claimed range; Product must pass through and compress 5 ~ 8mm and could satisfy and the coincidence pattern specification requirement, and the weld strength between the parts that connect through the soldering between the revised product chips of this technology can reduce greatly, thereby has influence on durability of products and reliability.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art; A kind of high-level plate fin oil cooler assembling jig is provided; It designs original assembling jig again; Employing press-fits principle, and the assembly tooling according to high-level oil cooler profile customization band position limiting structure is assembled the oil cooler product and highly kept unanimity before soldering.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of high-level plate fin oil cooler assembling jig; Said high-level plate fin oil cooler assembling jig comprises the assembling jig seat; The both sides of said assembling jig seat are equipped with assembling height limited post; The upper and lower end of said assembling height limited post is respectively arranged with weld jig plate and following weld jig plate, and following weld jig plate is connected with the assembling jig seat, and last weld jig plate top surface is provided with lower lock block.
The utility model is through design original assembling jig again; Employing press-fits principle, according to high-level oil cooler profile, has customized the assembly tooling of band position limiting structure; Assembling height limited post defines the cooler total height; When pressing down spacing putting in place, the height of cooler has just kept relative unanimity, the oil cooler product is assembled before soldering highly kept unanimity.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1; The utility model provides a kind of high-level plate fin oil cooler assembling jig; Said high-level plate fin oil cooler assembling jig comprises assembling jig seat 1, and the both sides of said assembling jig seat are equipped with assembling height limited post 2, and the upper and lower end of said assembling height limited post is respectively arranged with weld jig plate 3 and following weld jig plate 4; Following weld jig plate is connected with the assembling jig seat, and last weld jig plate top surface is provided with lower lock block 5.
The utility model is through design original assembling jig again; Employing press-fits principle, according to high-level oil cooler profile, has customized the assembly tooling of band position limiting structure; Assembling height limited post defines the cooler total height; When pressing down spacing putting in place, the height of cooler has just kept relative unanimity, the oil cooler product is assembled before soldering highly kept unanimity.
When utilizing the utility model; Soldering processes are adjusted; The principle that utilization is expanded with heat and contract with cold; Adjusted the pressure and the time of cooling inflation, gas-filling temperature is adjusted to 820 ℃, 40min from original 980 ℃, 30min, and oil cooler when having reduced vacuum welding is because gas-filling temperature charges into too fast with protective gas and causes that product is out of shape excessive problem.
In addition, the high temperature resistant molybdenum sheet of cushioning between adpting flange and weld jig reaches the required state of shaping after making product vacuum brazing, is convenient to follow-up shaping and handles.
The utility model adopted press-loading process to solve high-level oil cooler in high-temperature vacuum assembling and brazing process, to occur highly uppity problem easily, reduced and reduced the risk of this family machine oil cooler product reliability and durability reduction after through pressure correction after the soldering; The adjustment and optimized soldering processes, reduced product and cooled off the excessive problem of too fast distortion, as far as the high-level plate fin oil cooler product of high heat exchange power, be a kind of effective production and manufacturing process.
The utility model has solved prior art need stay the problem of welding correcting margin to high-level oil cooler product; And then farthest reduced the laggard line height correction of this family machine oil cooler soldering; Adopt external force hydraulic pressure shaping and cause the possibility of chip chamber solder side damage, guaranteed the weld strength of vacuum brazing; Because soldering is highly controlled, also reduce the workload of follow-up shaping simultaneously, improved production efficiency of products.
Only need to reserve 1～2mm allowance after the utility model soldering; And reduced the operation that external force compresses; Avoided stress property damage to solder side; Improved the welding quality and the reliability of product dramatically, for high-level oil cooler product, had bigger promotion and application and be worth.
The high-level plate fin oil cooler of the utility model production belongs to high-level plate fin oil cooler product; Be applied in peculiar to vessel or use on the super high power Diesel engine of power station as major impetus in the land more; Portioned product also is applied on the science and techniques of defence equipment, and product must possess good cooling heat dissipation performance and high reliability.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
