DEVICE FOR MACHINING PARTS OF IRREGULAR SPATIAL SHAPE

FIELD: mechanical engineering. SUBSTANCE: device that can be used for grinding, polishing, and milling parts, for instance aircraft engine blades, has machining tool installation assembly and work piece setting assembly. Work piece setting assembly is made in the form of multiple-link manipulator incorporating drive for setting work piece in rotary displacement as well as drive and slave members. Drive and slave members form plain mechanism built of two drive members each joined with base through rotary pair and coupled with respective slave member. One of slave members is joined through rotary pair with other slave member which is essentially output member of multiple-link manipulator. Multiple-link manipulator is provided with rotary motion drive set on output member and joined with work piece rotary motion drive. Machining tool installation assembly is made in the form of double-link manipulator. Output member of mentioned double-link manipulator is fastened to base and has drive coupled with output member. Output member has two rotary tool drives. Multiplelink manipulator is provided with mechanism for reducing gravitational thrusts on manipulator made in the form of pneumocylinder. EFFECT: enhanced operating reliability of device and precision of work piece machining; reduced metal input. 4 cl, 1 dwg
