<p>In a die positioning /74 fixing device that positions and fixes a die (M) on the surface (2a) of a plate member (2) in directions parallel to the surface and in the direction orthogonal to the surface: the die and the plate member include a first positioning mechanism (10P) that positions the die in directions parallel to the surface, a second positioning mechanism (20P) that performs positioning and that is disposed at a position apart from the first positioning mechanism (10P), and an orthogonal direction positioning mechanism (5P) that positions the die in the direction orthogonal to the surface; each of the positioning mechanisms (10P, 20P) includes a plate member side tapered convex engagement portion (12, 22) and an annular engagement portion (31, 41) that is provided on the side of the die and that is capable of engaging with the tapered convex engagement portion; there are provided with a plurality of bolt holes (13, 23) that are formed on the plate member side, a plurality of bolt through holes (7a) that are formed on the die, and a plurality of clamping bolts (9) each of which can be passed through one of these bolt through holes and can be screwingly engaged into one of the bolt holes; and, due to the engaging operation of the clamping bolts, each of the annular engagement portions (31, 41) is elastically deformed so as to increase its diameter, so that it is closely engaged with the corresponding tapered convex engagement portion (12, 22).</p> |
