[0002] The oil cooler is a heat dissipation device that accelerates the heat dissipation of lubricating oil and keeps it at a low temperature. It is mainly composed of a base plate, a heat dissipation core and a cover plate, and the heat dissipation core is mainly composed of a rib plate and a fin. After the above components are assembled, they are usually clamped by a fixture and then sent to a vacuum brazing furnace for welding. After searching the stacked oil cooler vacuum brazing fixture with the publication number CN109551076A, the scheme discloses a positioning component and a clamping component; the positioning component is composed of a support block and a positioning pin fixed on the surface of the lower channel steel, and three stepped support shafts fixed on the surface of the lower channel steel. Although this scheme can clamp the oil cooler, the tooling is large in size and requires more energy for heating and welding, resulting in high energy consumption during the production process, which no longer meets the existing low-consumption production needs. In addition, since the pressure plate is made of stainless steel, it will deform as the temperature rises during the heating process, resulting in uneven clamping, causing some welds to be unable to be effectively welded, seriously affecting product quality.

[0005] As a further improvement, the base plate is provided with mounting holes for positioning the oil cooler.

[0006] Furthermore, a plurality of pin holes matching with the positioning pins in the brazing furnace are provided around the bottom plate.

[0007] Furthermore, the gusset plate is in an I-shaped structure, and both ends of the bottom plate and the clamping plate are movably sleeved in the gusset plate.

[0008] Furthermore, the graphite pressing plate is provided with an arc-shaped giving way groove.

[0009] Furthermore, the limiting member is a clip, and the clip is connected to the sliding rod above the clamping plate.

[0010] Furthermore, the number of the sliding rods is two, and the two sliding rods are symmetrically arranged on the cross pressure plate.

The oil cooler 10 is pressed by the graphite pressing plate 21. Compared with stainless steel, the graphite pressing plate 21 has a smaller density and better thermal conductivity, so that on the one hand, the weight can be reduced, thereby reducing the energy consumption required for the oil cooler 10 to reach the welding temperature. On the other hand, the graphite pressing plate 21 will not deform at high temperature, thereby ensuring the flatness of the product and effectively improving the quality of the product. The entire tooling structure is simple, the number of parts is small, and the weight is effectively reduced by 50% compared with traditional tooling, so that the power consumption of brazing is reduced by 30%, thereby effectively reducing energy consumption and playing a role in reducing costs and increasing efficiency.

[0019] Specifically, the base plate 1 is provided with mounting holes 5 for positioning the oil cooler 10 , so that the oil cooler 10 is positioned and fixed on the base plate 1 , thereby preventing deviation during the pressing process and improving the welding quality.

The oil cooler 10 is pressed by the graphite pressing plate 21. Compared with stainless steel, the graphite pressing plate 21 has a smaller density and better thermal conductivity, so that on the one hand, the weight can be reduced, thereby reducing the energy consumption required for the oil cooler 10 to reach the welding temperature. On the other hand, the graphite pressing plate 21 will not deform at high temperature, thereby ensuring the flatness of the product and effectively improving the quality of the product. The entire tool has a simple structure and a small number of parts. Compared with traditional tooling, it can effectively reduce the weight by 50%, so that the power consumption of brazing is reduced by 30%, thereby effectively reducing energy consumption, playing a role in reducing costs and increasing efficiency.
