Problems solved by technology

However, after the auxiliary positioning is pulled out, there will still be displacement between the product parts; and the transportation process will also cause secondary displacement between the parts, which are unavoidable
Due to the displacement of parts, the installation size is dislocated, and the user cannot use it

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 [0001] The invention relates to the field of automobile manufacturing, in particular to a stainless steel plate-fin type engine oil cooler component on an automobile. Background technique [0002] At present, the stainless steel plate-fin oil cooler has the characteristics of high thermal conductivity, large bearing pressure, and compact structure. If the structure is compact, the dimensional accuracy of the required installation and connection will also increase correspondingly, which will bring difficulties to the manufacture of the oil cooler. The stainless steel plate-fin oil cooler adopts the vacuum brazing process. In order to ensure the installation and connection dimensions, brazing fixtures are required to maintain the mutual positional relationship between the parts. During the brazing process, the solder in the vacuum melting state will generate capillary phenomenon under the action of the surface tension of the material, and flow to the place wit...
