A modular structure (1), particularly for supporting blanks, which comprises at least one flat plate (2) which has a plurality of seats (3) which can be integrally and removably associated with at least one portion (7, 52, 53) of a blank (50, 51) to be worked on by way of fixing means (9). In more detail, the fixing means (9) comprise at least one fixing element (10, 11) which can be interposed between the plate (2) and the blank (50, 51) and has at least one upper portion (10a, 11a) which can be faced towards at least one among the plate (2) and the blank (50, 51). The upper portion (10a, 11a) is moreover provided with at least one first pin (12) which can be associated, respectively, with a seat (3) or with the portion (7, 52, 53) and can be inserted along its axis (12a) in a first cavity (13) defined by the upper portion (10a, 11a) through a first circular hole (14) defined on the surface of the upper portion (10a, 11a) which can be faced in the direction, respectively, of the plate (2) or of the blank (50, 51) for the radial locking in place of the first pin (12) relative to the upper portion (10a, 11a). The first cavity (13) accommodates a pair of first jaws (16) which can be engaged with the first pin (12) for its axial locking in place relative to the upper portion (10a, 11a). The distinctive characteristic of the invention consists in the fact that the fixing element (11) has at least one lower portion (11b) which can be faced towards the plate (2) and which is provided with at least one second pin (23) which can be engaged, respectively, with a seat (3) of the plate (2), and can be inserted along its axis (23a) in a second cavity (24) defined by the lower portion (11b) through a second hole (25) with a substantially elongated shape along a predefined direction (26) and is substantially perpendicular with respect to the axis (23a) of the second pin (23). In more detail, the second hole (25) is defined on the surface of the lower portion (11b) which can be faced in the direction of the plate (2) for the locking in place of the second pin (23) relative to the lower portion (11b) along a radial direction of the second pin (23) which is substantially perpendicular to the predefined direction (26). Moreover, the second cavity (24) accommodates a pair of second jaws (27) which can be engaged with the second pin (23) for its axial locking in place relative to the lower portion (11b) and which are movable in the second cavity (24) along a direction which is substantially parallel to the predefined direction (26).
