Abstract
The utility model discloses a limiting structure for a rivet head of a riveting machine. The limiting structure for the rivet head can avoid the phenomenon that a lower riveting air cylinder of the riveting machine impacts on a rivet on a riveted product and consequentially, an upper rivet head of an upper riveting air cylinder displace upwards and comprises a supporting frame of the riveting machine, the upper riveting air cylinder and the lower riveting air cylinder. The front end of a piston rod of the upper riveting air cylinder is provided with a pushing block which moves horizontally. An exerting block which can vertically move downwards and exert impacting force on the riveted product is arranged in front of the pushing block. When the upper riveting air cylinder pushes the pushing block forwards, under the action of the pushing block, the exerting block moves downwards to impact on the riveted product. When the exerting block carries out riveting on the rivet on the riveted product, the lower bottom face of the pushing block is just in rigid face contact with the upper end face of the exerting block and at the same time, the lower riveting air cylinder impacts on the riveted product and will not shake the exerting block to displace upwards, so that even and uniform acting force is obtained. Thus, the height difference between an upper end and a lower end of the rivet is minimal.
