It is placed on the mounting plane of fixture, two of which cushion block A is located at the both ends of outer hat segmental arc respectively, and another is located at interior hat segmental arc
Middle part；
（c）Carry out side end face and radial positioning to static cascade segmental arc, levelling static cascade segmental arc steam admission side, and from attachment strap pair
Static cascade segmental arc carries out pre-pressing；
（d）Three Height Adjustable cushion block B, two of which cushion block B difference position are placed between fixture and static cascade segmental arc
In the both ends of interior hat segmental arc, another is located at the middle part of outer hat segmental arc, and the height for adjusting cushion block B makes which be affixed with steam output side,
And levelling static cascade segmental arc steam admission side again；
（e）Static cascade segmental arc is compressed from the attachment strap of outer hat and interior hat, complete the clamping centering of static cascade segmental arc.
Further, the step（b）In, static cascade is primarily determined that by round wires are delineated on the mounting plane of fixture
The initial riding position of segmental arc and cushion block A, the round wires are close or consistent with hat circular arc outside static cascade segmental arc.
The step（c）And step（d）During levelling static cascade segmental arc steam admission side, go out vapour at each cushion block A places by adjusting
The distance between side and fixture mounting plane, make the maximum difference of distance at three be less than 0.5mm.
A kind of static cascade segmental arc Milling Process quick-clamping centering fixture, including plate body, one group of height be fixed and consistent
The Height Adjustable cushion block B of cushion block A and one group；It is provided with what is radially positioned with side end face for static cascade segmental arc on the plate body
Detent mechanism, the radial direction jacking mechanism radially held out against for static cascade segmental arc and the pressing machine installed for static cascade segmental arc compression
Structure.
Further, the press-loading device includes connecting screw rod, pressing plate and studdle, and the connecting screw rod passes through screw thread
It is connected on plate body, the pressing plate is sheathed in connecting screw rod, and studdle is threadedly coupled with pressing plate and is arranged at after pressing plate
End.
Further, the detent mechanism includes the pin of main body block and eccentric setting in main body block, the main body block
