END SUPPORT CLAMP FOR ELIMINATING DEFORMATION AND VIBRATION OF FREE STANDING LP TURBINE BLADES DURING TIP END CUTTING ON VERTICAL MILLING MACHINE

摘要

An end support clamp for eliminating deformation and vibration of free standing LP turbine blades during tip end cutting on vertical milling machine is made of a base (1) fixed to the machine base, a unit (2) having a slotted portion (12) at the top for accommodating unit (3), a unit (3) having a window slot (13) and a slot (14) for accommodating unit (4) when unit (3) is fixed with unit (2) using T- nut and a bolt. The T-nut fits into the T-slot P2 of unit (2). Unit (4) bolted to unit (3), is having slot (9) for facilitating the unit (5) to move up and down. A unit 6 is placed over unit (5) with the help of a hinge pin (15), spring (7) and a bolt (10) for clamping the blade (11). All units are hardened and ground.
