Claims

[Claims for Utility Model Registration] After lowering the drift with a ram and press-fitting the object to be press-fitted into the press-fitting hole of the housing by the pressing part formed on the drift, the punch of the drift is pressed into the press-fitting hole with the upper surface of the housing. In the caulking device for caulking the press-fitted object by biting into the periphery so that the peripheral edge of the press-fit hole protrudes so as to cover the upper end of the press-fitted object, the ram is provided with a piston rod that protrudes toward the drift side, and the piston rod protrudes toward the drift side; By inserting the piston rod into the cylinder formed by the piston rod, the drift can be moved up and down with respect to the ram, and a pressure chamber is defined in the cylinder, and the drift can be moved downward between the drift and the ram. By providing a biasing spring, and inserting the punch into a guide hole formed in a drift direction so as to be inclined toward the center line of the object to be press-fitted, and which communicates with the pressure chamber, the punch can be freely advanced and retracted.
When the pressing unit completes press-fitting the press-fit object into the press-fit hole, the spring is compressed to increase the pressure in the pressure chamber, and the punch is pressed in a forward direction to caulk the press-fit object. A caulking device characterized by:
