PURPOSE:To obtain a punch holder that can mount rectangular punches of different size quickly and surely by constituting the holder of a fixed block, two movable blocks which are in sliding contact with the one side and the end face, respectively, and a movable block that is driven by the movable blocks. CONSTITUTION:A holder 4 is formed by providing a fixed block 5 attached in a body to a fixed base 2 and movable blocks 6, 7, 8 on the face of a fixed base 2 on which a fitting part 1 is projected on the flat side end of a punch holder. The first movable block 6 is in sliding contact with the chucking face 5a of the fixed block 5 and reciprocated in the direction of arrow X by operation of a bolt and nut mechanism B1. The second movable block 7 is reciprocated in the direction of arrow Y by a bolt and nut mechanism B2. At the same time it follows the movement of the first movable block 6. The third movable block 8 is in sliding contact with the end face 5b of the fixed block 5 and is capable of reciprocating in the direction of arrow Y. |
