Abstract
The invention discloses molten-loss type brazing auxiliary positioning for an oil cooler. The molten-loss type brazing auxiliary positioning for the oil cooler comprises a clamp body, the oil cooler, an upper clamp body, center positioning, a screw nut and circular hole positioning, wherein the oil cooler is placed on the clamp body and is positioned on the clamp body through the center positioning and the circular hole positioning; and the upper clamp body is tightly pressed on the oil cooler through the screw nut. According to the invention, the molten-loss type brazing auxiliary positioning is used for the center positioning and the circular hole positioning, thus the tightly pressing and the carrying after the oil cooler is assembled can be ensured; and the reliable position can be ensured prior to melting of the solder of a product by brazing, thus the mounting position for the product is ensured to be accurate.
Description
Technical field
The present invention relates to automobile manufacturing field,, be specifically related to fine-type stainless steel plate oil cooler parts on a kind of automobile.
Background technology
The fine-type stainless steel plate oil cooler has coefficient of heat conduction height at present, and bearing pressure is big, characteristics such as compact conformation.Compact conformation, also corresponding the increasing of installation size for connection precision that then needs, the manufacturing that this gives oil cooler brings difficulty.The fine-type stainless steel plate oil cooler adopts vacuum brazing technique, in order to guarantee to install size for connection, needs to adopt brazing jig, to keep the mutual alignment relation between each part.In the brazing process, scolder can be under the effect of material surface tension force at the vacuum fusion state; Produce capillarity, flow brazing jig and oil cooler contact surface to the place that the gap is little; Also can receive capillary influence; Produce welding, cause anchor clamps can't separate with product, final products are scrapped.In order to prevent the generation of above-mentioned situation, during general jig Design, adopt assist location.Shown in accompanying drawing one, during assembling, on clamp body 1, place oil cooler 2 each parts; Through center assist location 4 and auxiliary circular hole location 6, confirmed the position of parts, when assembling finishes; Assist location 4 and 6 is extracted, will go up clamp body 3 again, clamp through nut 5.Assist location is extracted in employing, reduces anchor clamps and contacts with product, prevents the welding of anchor clamps and product.But, after assist location is extracted, between the product component, still can produce displacement; Also have transportation, can cause the second displacement between the parts equally, these all are difficult to avoid.Because the displacement of parts causes the installation dimension dislocation, the user can't use.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, provide a kind of oil cooler to melt mistake formula soldering assist location.
The technical scheme that the present invention adopts is: a kind of oil cooler melts mistake formula soldering assist location; Comprise clamp body, oil cooler, last clamp body, centralized positioning, nut and circular hole location; Said oil cooler is placed on the clamp body; And be positioned on the clamp body through centralized positioning and circular hole and locate, the said clamp body of going up is pressed on the oil cooler through nut.
Fine-type stainless steel plate oil cooler of the present invention melts mistake formula soldering assist location; Its centralized positioning and circular hole location; The material that adopts is the T2 copper the same with the product scolder, can guarantee to have identical soldering fusion temperature with the oil cooler product, the assist location material of fusing; Can directly apply to welding, strengthen the weld strength of product.What molten mistake formula soldering assist location material adopted is T2 band material, and the material bandwidth is consistent with assembling rear-locating face height, material thickness 0.1-0.15mm.During making, will be with circular or other shapes of material circle, be wrapped on the mash welder special core rod, through spot welding, fixing corresponding shape and size.
Beneficial effect: centralized positioning of the present invention and circular hole location, use be molten mistake formula soldering assist location, can guarantee to compress, carry after the assembling, before product scolder soldering fusing, all can guarantee to locate reliably.Therefore, guaranteed the accurate of product installation site.
Description of drawings
Fig. 1 is original oil cooler soldering assist location sketch map;
Fig. 2 is molten mistake formula soldering assist location sketch map.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described further:
As shown in Figure 2: a kind of oil cooler melts mistake formula soldering assist location; Comprise clamp body 1, oil cooler 2, last clamp body 3, centralized positioning 7, nut 5 and circular hole location 8; Said oil cooler 2 is placed on the clamp body 1; And through centralized positioning 7 and location on clamp body 1, circular hole location 8, the said clamp body 3 of going up is pressed on the oil cooler 2 through nut 5.
Said centralized positioning 7 is a T2 copper with the material of circular hole location 8.
Claims (2)
