Modular structure for supporting blanks

A modular structure, particularly for supporting blanks, which comprises at least one flat plate which has a plurality of seats which can be integrally and removably associated with at least one portion of a blank to be worked on by way of fixing means, said fixing means comprising at least one fixing element which can be interposed between said plate and said blank and having at least one upper portion which can be faced towards at least one among said plate and said blank and which is provided with at least one first pin which can be associated with either one of said seats or with said upper portion, and can be inserted along an axis of said first pin in a first cavity defined by said upper portion through a first circular hole defined on the surface of said upper portion which can be faced in the direction of either said plate or of said blank for the radial locking in place of said first pin relative to said upper portion, said first cavity accommodating a pair of first jaws which can be engaged with said first pin for an axial locking of said first pin in place relative to said upper portion, wherein said fixing element has at least one lower portion which can be faced towards the other among said plate and said blank and which is provided with at least one second pin which can be engaged with either one of said seats or with said lower portion, and can be inserted along an axis of said second pin in a second cavity defined by said lower portion through a second hole with a substantially elongated shape along a predefined direction which is substantially perpendicular with respect to said axis of said second pin, said second hole being defined on the surface of said lower portion which can be faced in the direction of either said plate or of said blank for the locking in place of said second pin relative to said lower portion along a radial direction of said second pin and which is substantially perpendicular to said predefined direction, said second cavity accommodating a pair of second jaws which can be engaged with said second pin for its axial locking in place relative to said lower portion and which are movable in said second cavity along a direction which is substantially parallel to said predefined direction.
