PURPOSE: A hole machining jig for a press die is provided to be compatible with various sorts and standards of workpieces and to improve work efficiency by accurately and easily setting a machining point of a workpiece. CONSTITUTION: In the case of a hole machining jig of a press die, a workpiece setting jig(3) is mounted on a base plate(1) having a rectangular section. Left and right slide plate guides(5,7) are parallel placed at one side of the workpiece setting jig on the base plate. A slide rail(9) is placed between the slide plate guides. One end of the slide rail is fixed on the side of the workpiece setting jig while the other end of the slide rail is fixed on the base plate. A slide plate(17) is fitted into the slide rail along two rail guides. The rear end of the slide plate has an inclined face(25) inclining against a press die. Upon lifting up and down of the press die, an inclined face of the press die contacts with the inclined face of the slide plate and enables the slide plate to forward and rearward slide between the left and right slide plates. Then, a hole punch(29) mounted in the front side of the slide plate machines a hole of a machining point on a workpiece(13) set on a setting plate(15) of the setting jig. The hole machining jig offers compatibility with various sorts and standards of workpieces, and machining point of the workpiece is set up easily.
