FIXTURE FOR SUPPORTING END SHIELD OF TURBO GENERATOR DURING DRILLING OF HOLES ON JOINT PLANE ON RADIAL DRILL MACHINE

摘要

The invention discloses a fixture (F) for supporting on half of the end shield at a time for drilling of holes on joint plane comprising a horizontal base (1) with a vertical support (2) on which the end shield (16) is mounted in such a manner that the joint plane is towards the top. A hydraulic jack ram is attached to the plate (15) integral to the end shield while that plate rests on the plate support (9). Plurality of gussets (3) are welded on the base (1) and vertical support (2) in order to strengthen vertical support (2). To pick and place the fixture (F) on the machine bed, holes for lifting hooks (4) are used. Half end shield is completely supported on the fixture (F) in such a way that the semi-circular periphery of the end shield rests on plurality of roller (14) and thus end shield can rotate about its center axis. End shield after final adjustment is clamped rigidly at its position using clamps (12). For different rating of turbo generator, size of end shields are different and to accommodate the variation of size, rollers (14) will be placed in the plurality of threaded holes (5, 11, 13) and thereupon accordingly three threaded holes (6, 7, 8) are provided for clamping the half end shield.
