PURPOSE:To facilitate the positioning of a clamp and to permit the mounting of a core holding jig to a core setting body with high accuracy by providing means which support the top and bottom of rods with spherical surfaces and guide the core holding jig by tapered surfaces to support said jig to the clamping members provided on the core holding jig side. CONSTITUTION:The clamping members 28 are guided by tapered supporting surfaces 34 and tapered receiving surfaces 35 and are supported in the centering state to supporting members 29 which are fixed to the core holding jig 20. Positioning recesses 32 and positioning projections 33 are fitted to each other when a core setting body 18 is lowered. The members 28 are pulled up by clamping arms 22 when the arms 22 are turned and vertically moved so that the jig 20 is clamped to the body 18 at the members 29. The jig 20 is made floatable from the core setter 18 in this clamping state as the jig is supported by the top and bottom surfaces of the rods 30. The accuracy of mounting the core holding jig is thus improved. |
