ADJUSTABLE SUPPORT OF WORKING SURFACE Russian patent published in 2020 - IPC G12B5/00 G01B21/00 G12B9/08 G01D11/30 B23Q3/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to machine building, and can be used in surface design and calibration for industrial working surfaces processing systems and printed precision 3-coordinate systems installed on controlled supports. Adjustable support of the working surface consists of a rod with a nut screwed on it, of an upper metal support plate provided with holes, of the lower support part, into the central hole of which the lower end of the rod having a thread is screwed. At that, upper part of rod is pressed into hinge ball enclosed in housing, at that housing outside is rigidly connected to center of support plate; lower support part is made in the form of a metal bushing. There are seats for key on rod. Upper support plate and sleeve are made of rigid metal.

EFFECT: high strength, reliability and degrees of freedom of the structure of the adjustable support, which enable to achieve precision flatness of the working surface.
