Abstract
A device for positioning a module of modular bed (4) for machine tools with respect to a reference module (41), comprising a liquid-based leveling device (2) which allows an alignment of the modules (41, 42) according to three degrees of freedom (Z,a,b) and a base support (3) which allows a spatial movement of the module to be installed (42) at least according to the three degrees of freedom (Z,a,b).
Claims9
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).
The positioning device (1) according to one or more of the preceding claims, characterized in that said positioning bulbs (21, 22, 23, 23′) and said reference bulbs (24, 24′) are graduated.
The positioning device (1) according to one or more of the preceding claims, characterized in that it comprises a system for the measurement of the level of a liquid inside said positioning bulbs (21, 22, 23, 23′) and said reference bulbs (24, 24′).
The positioning device (1) according to one or more of the preceding claims, characterized in that it comprises a tank (28) which is in hydraulic communication with the positioning bulbs (21, 22, 23, 23′) and the reference bulbs (24, 24′), said tank (28) being preferably provided with a valve in order to be filled and emptied with a measurement liquid.
The positioning device (1) according to one or more of the preceding claims, characterized in that the interface element (33) also comprises, in addition to the ball-type transfer units (34), a second plate which can slide on the ball-type transfer units (34) with the ball-type transfer units (34) interposed between the first and second plates.
A method for positioning a module of modular bed (4) for machine tools, wherein the modular bed (4) comprises a reference module (41) with at least two guide-equipped longitudinal members (45) which are parallel and are arranged on a horizontal plane, and a module to be installed (42) which is spatially aligned with the reference module (41), the positioning method comprising the following steps:
- a—providing a liquid-based leveling device (2) which comprises three positioning bulbs (21, 22, 23) and a reference bulb (24) which are mutually in fluid communication, in order to constitute a system of communicating vessels;
- b—coupling the positioning bulbs (21, 22, 23) to a module to be installed (42) and the reference bulb (24) to a reference module (41);
- c—providing a base support (3) which comprises a first plate (31) and supporting feet (32) which are connected to the first plate (31) and are each independently adjustable in extension with respect to the first plate;
- d—suspending the module to be installed (42) on the base support (3),
- e—adjusting the supporting feet (32) until the free surface levels of the fluid of the positioning bulbs (21, 22, 23) and of the reference bulb (24) are mutually aligned,
- f—locking the module to be installed (42) in position.
