VACUUM COMPLEX FOR FIXATION OF WORKPIECES IN WORKING ZONE OF PORTAL MILLING MACHINE Russian patent published in 2024 - IPC B23Q3/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used in designs of vacuum tables for fixation of workpieces in the working zone of portal milling machines with numerical control. Complex comprises a vacuum table made with possibility of installation on a machine frame and consisting of at least two perforated modules, a vacuum pump, which by means of a high-level vacuum line with a line actuation valve located in it is connected to the perforated modules with the possibility of selective creation of a high-level vacuum on the surface of at least one perforated module. Complex is also equipped with at least one air blower, which is connected by means of an air-vacuum main line with a main line actuation valve in it to perforated modules with the possibility of creating an air cushion or low-level vacuum on their surfaces. Said connections of modules have control valves and connections with control modules connected to appropriate control units.

EFFECT: use of the invention allows extending the technological capabilities of the complex.
