APPARATUS FOR MOUNTING AND FASTENING BLADES OF GAS TURBINE ENGINES Russian patent published in 2007 - IPC B23Q3/00 

FIELD: processes for manufacturing blades of compressor of gas turbine engines, namely operations for milling flow-through portions of blades, possibly for mounting and fastening blades with significantly large size of flow-through portions of blades.

SUBSTANCE: apparatus includes base, arranged on said base housing with groove, two mounting centers arranged on the same axle with possibility of motion along it; one closing center. Axis of closing center is normal to axes of mounting centers arranged in walls of housing groove at both sides relative to axis of closing center. On one wall of housing groove with mounting center there is basic surface. Spacing from said surface till axis of closing center is equal to distance between axis of part and its base end. Housing is in the form of frame having two struts and two cross bars. Groove for placing part is through one. Mounting centers are arranged in struts and closing center is arranged in cross bar of frame. Basic surface is formed on inner surface of one strut. Apparatus is provided with plates. Ends of plates are secured to opposite struts of frame at each side. On part of plates arranged over groove of frame threaded fastening members are mounted with possibility of axial motion.

EFFECT: increased rigidity and enhanced reliability of fastening parts at working, enlarged manufacturing possibilities of apparatus.
