An indexing and clamping fixture for drilling operation on taper surface of core press ring of all types of turbo generators and the process for the same
The invention relates to an indexing and clamping fixture for drilling operation on taper surface of core press ring of all types of turbo generators and the process for the same. The fixture comprises of a plurality of cross arms (6), a plurality of taper seat (1), a plurality of threaded holes (2,4,5) , a plurality of adjustable slot carrier (3) and a plurality of adjustable slot (7). The taper seat (1) of the fixture accommodates the taper part of the core press ring. The fixture is placed on a rotary table. The taper seat has 15 degree taper. The rotary table is rotated to make the taper face of the job horizontal for drilling of one hole. For drilling of next hole, the rotary table is manually rotated.
