1. A device (1) for positioning a module of modular bed (4) for machine tools, wherein the modular bed (4) comprises a reference module (41), with two longitudinal members (45) equipped with guides, which are parallel and arranged on a horizontal plane, and a module to be installed (42) which is spatially aligned with the reference module (41), the positioning device (1) comprising:
a liquid-based leveling device (2) which comprises
at least three positioning bulbs (21, 22, 23)
at least one reference bulb (24),
the three positioning bulbs (21, 22, 23) and the reference bulb (24) being mutually in fluid communication, so as to constitute a system of communicating vessels,
the three positioning bulbs (21, 22, 23) being associable with the module to be installed (42) and the reference bulb (24) being associable with the reference module (41), so as to allow an alignment of the modules (41, 42) according to three degrees of freedom (Z,a,b);
a base support (3) which comprises
a first plate (31) and
supporting feet (32) which are connected to the first plate (31),
the feet (32) being each adjustable independently in extension with respect to the first plate (31)
so that the base support (3) allows a spatial movement of the module to be installed (42) at least along said three degrees of freedom (Z,a,b).
