SPATIAL IRREGULAR-SHAPED ITEMS MACHINING DEVICE Russian patent published in 2009 - IPC B24B19/14 B23C3/18 B25J9/08 

FIELD: engineering industry.

SUBSTANCE: invention refers to engineering industry, and can be used for grinding, polishing and milling spatial polysurfaces of details, and namely propeller blades, working part of gas, steam or hydraulic turbine blades. At the device bottom there arranged is the point for installing the machining tool with the tool rotary drive, and the point for installing the machined item in the form of multilink manipulator. There provided are two mechatronic modules of rotary and translational movements - machined item movement module and cutting tool rotary drive movement module. Each module consists of a housing, splined bush, nut and outlet shaft. Stators of two synchronous electric motors are fixed on the housing, rotor of the one synchronous electric motor - on splined bush, and rotor of the other synchronous electric motor - on the nut. Outlet shaft is connected by means of a rectilinear kinematic pair made in the form of a spline connection to splined bush, and by means of a screw pair - to nut. Outlet shaft is hollow. Nut and splined bush are connected to the housing by means of turning pair made in the form of ball bearing or slide bearings. All kinematic pairs of each mechatronic module of rotary and translational movements have a common axis. There provided is at least one kinematic pair with the appropriate drive which is intended for moving the cutting tool rotary drive movement module housing relative to machined item movement module housing.

EFFECT: improving accuracy and efficiency of processing due to decrease of a number of kinematic pairs and movable links, and decrease of mass thereof.
