A riveting structure for fixing an inlet and outlet pipe and a core body of an oil cooler comprises the inlet and outlet pipe and the core body. The inlet and outlet pipe forms a convex rib through rolling, the included angle between the lower inclined surface of the convex rib and the central line of the pipe is 50-60 degrees, the core body comprises a top plate and a chip, the top plate is provided with a flanging round hole with a guide bevel angle, and the guide bevel angle is consistent with the angle of the lower inclined surface of the convex rib of the inlet and outlet pipe. And the inlet and outlet pipe is assembled on the top plate turnup round hole with the guide bevel angle through riveting and is brazed with the chip to form the oil cooler. The lower inclined surface of the convex rib of the inlet and outlet pipe is tightly matched with the flanging round hole with the guide bevel angle of the top plate, so that manufacturing errors of parts can be compensated, the brazing area of the inlet and o
