Pressing rivet structure of automobile engine wind shielding ring assembly

Abstract

The invention provides a pressing rivet structure of an automobile engine wind shielding ring assembly. The open-type pressing rivet structure is arranged on the outer wall or the inner wall of a journal of a wind shielding ring. The pressing rivet structure is characterized in that the opening of the open-type pressing rivet structure faces outwards or inwards; the included angle between the opening direction of the open-type pressing rivet structure and the outer wall or the inner wall of the journal of the wind shielding ring ranges from 0-90 degrees; the number of the opening of the open-type pressing rivet structure is one or two, and a boss is arranged on the inner wall of the opening; and the side edge of the outer circumference or the inner circumference of the opening of the open-type pressing rivet structure is folded upwards so that the opening of the open-type pressing rivet structure can be in a half-surrounded structure. The pressing rivet structure is convenient to implement, and the pressing rivet force application direction is parallel to the axis direction of the wind shielding ring, that is, the force application direction ranges from 0-90 degrees. Thus, limitation of pressing rivet equipment and pressing rivet operation space on pressing rivet force application is small, the opening of the pressing rivet structure can shrink easily, proper elastic deformation of a rubber sealing ring is ensured, that is, the opening of the pressing rivet structure shrinks so that the rubber sealing ring can be deformed elastically, then the rubber sealing ring is tightly clamped, and the wind shielding ring is formed.

Description

technical field [0001] The invention relates to a heat dissipation device of an automobile engine, in particular to a pressure riveting structure of an automobile engine wind protection ring assembly. Background technique [0002] The assembly diagram of the existing wind protection ring and related assembly parts is attached figure 1 , 2 shown. The windshield 1 is made of two materials, metal and plastic, and most of them are made of steel plate materials. The specific process is: blanking → rounding → shaping → welding → flanging → punching → trimming. Radiator windshield 5 adopts injection molding process to make mostly, is a plastic part. During the assembly process, first put the American throat clamps 2 and 4 (the clamps are standard parts with one-way sliding locking function) in the corresponding grooves of the sealing ring 3, and the clamps are in the "loose" state at this time. The small end of the sealing ring 3 (diameter) is placed on the wind protection ring...
