DEVICE FOR MOVEMENT OF WORKING ELEMENT OF MACHINE WITH NUMERICAL PROGRAM CONTROL Russian patent published in 2019 - IPC B41F17/00 

FIELD: control systems.

SUBSTANCE: invention relates to production of process equipment with numerical program control, in which it is required to move tool working tool, at least along two coordinates to provide tool movement along complex trajectory. Examples of such equipment can be milling and engraving machines, thermal cutting machines (for example, plasma or laser), as well as 3D printers; in particular, 3D printers, in which the three-dimensional article production by digital 3D-model is implemented by extrusion deposition of the layers sequence in the product cross-section. Device for movement of working element of machine with numerical program control, comprising base, located on base of engines, two longitudinal guides located on the base along the Y axis, at least one transverse guide, located along the X axis between the longitudinal guides with possibility of movement on them, device for attachment of the working member, made with possibility to move at least one transverse guide by means of carriage, and belts, ends of which are fixed on carriage of device for attachment of working member, with possibility of belt contours formation, characterized by that it contains hinge fixed on base between longitudinal guides at equal distance from them, lever, fixed on hinge with possibility of rotation in plane XY (around axis passing through hinge perpendicular to this plane), and at least two rollers, rigidly fixed on ends of lever, through each of which passes at least one of belts.

EFFECT: disclosed device for movement of working element of machine with numerical program control.
