COORDINATE TABLE Russian patent published in 2011 - IPC B23Q1/26 

FIELD: machine building.

SUBSTANCE: invention refers to machine building, particularly to devices facilitating linear transfer of processed item along two mutually perpendicular axes. The coordinate table consists of modules of lengthwise and crosswise transfer. The module of lengthwise transfer consists of base 1 with guides 2, of bridge made in form of carriages 3 interacting with guides, of beam 4 and of carriages drives each made in form of a linear motor with inductor 5 and anchor 6. The module of crosswise transfer consists of guides 7 mounted on the beam of the bridge, of carriage 8 interacting with guides 7, of a carriage drive and of attached to the carriage head 9 with working element 10. The drive of the module of crosswise transfer corresponds to the linear motor with the inductor and anchor. The coordinate table is equipped with flexible elements 11, 12 attached to carriages 3 of the module of lengthwise transfer. Opposite ends of the flexible elements are tied with lower and upper parts of corresponding ends 13 and 14 of beam 4.

EFFECT: upgraded accuracy of positioning at simultaneous simplification of design.
