Patent ID: 7871064

Claim:
A repair fixture for supporting large cylindrical objects, such as a generator rotor, for disassembly, assembly and/or machining, that can vary the height of a centerline of the cylindrical object to accommodate various operations comprising: a plurality of spaced, parallel Vee-block supports having inclined upper surfaces defining a “V” with the nadir of “V” shape of each Vee-block aligned along the same axis so that the cylindrical object can be supported within the “V” groove; a stanchion positioned on either side of each Vee-block having a vertical groove that receives an end of the Vee-block so that the end of the Vee-block can translate vertically within the stanchion groove and be supported against movement in other directions; a plurality of devises rotatably affixed at a lower end respectively to a front side and a rear side of each Vee-block at each end of the Vee-block, so the clevises at each end are opposed to each other with the clevises at each end that are opposed being attached to each other at an upper end of the clevises with a brace therebetween to maintain the upper end of the devises spaced apart; a plurality of hydraulic or pneumatic cylinders each having a piston with an end of each piston connected to an upper end of the corresponding clevis, which upper end is spaced from the lower end, and with an end of the cylinder supported by a floor; and means for activating the pistons in unison so that the Vee-blocks are raised or lowered at the same time and at the same rate to maintain the cylindrical object level.
