Development of fixture for axial movement of roller support system for coupling with carden shaft of weld overlay machine for performing weld overlay on turbine rotor shafts

摘要

The invention relates to a fixture for providing axial movement to the roller support of Weld Overlay System in loaded condition in such a way that the flange of the rotor can be coupled with carden shaft of the weld overlay machine. The fixture comprises a support plate which is used to transmit the force to stem of roller support system, a hydraulic jack which is used to push roller support to couple with carden shaft, a base plate which is used to form the base for hydraulic jack, a pipe with adjustable length which is used for initial adjustment of fixture device & a rigid support which is used for generating reactive force to push the roller support system using the fixture.
