Claims

[Scope of utility model registration request]

In a rivet riveting machine used for rivet riveting work, two pressurizing cylinders are built into the tip of one end of a center column provided in the center on both sides in a vertical direction to the center column, and the two pressure cylinders are A pressure mechanism has a tip with a predetermined shape to receive a rivet at the tip of the cylinder, and one side is installed on each side in line with the pressure cylinder of the pressure mechanism and parallel to the center column. The side support has a stopper for fixing the side support to a rotating shaft that rotates around the axis of the side support, and a rod-shaped tip holder is disposed at the tip of the side support in alignment with the pressure cylinder. One piece is attached to each of the tip holders, and a stopper is provided so that the attachment position of the tip holder can be arbitrarily moved in line with the pressurizing cylinder, and one piece is attached to each of the tip holder end face processing cylinder sides.
a holding mechanism having a tip that receives a rivet and a screw provided on the tip holder side to finely adjust the height of the tip; a center column of the pressure mechanism and the other end of the side column of the holding mechanism; It consists of a main body that holds the main body, a base that supports the main body, and a pressure generator that is connected to the two pressurizing cylinders of the pressurizing mechanism and supplies pressure to the pressurizing cylinders. Two rivets can be caulked at the same time by only turning on and off the pressure supply, and even when caulking one rivet, the direction of pressure corresponding to the direction of the head attached to the workpiece can be obtained. A riveting machine featuring:
