At shelves endoporus；
One end of No. two bolts passes through No. two bolt holes.
A kind of steam turbine high-pressure cylinder described in the utility model opens a grade application method for finishing of internal diameter servicing unit：Will
The open slot of clamping support is placed in the flange of high pressure cylinder horizontal flange；Clamping support is fixed by swivel bolt；Adjustment
Measure briquetting so that one of face of measurement briquetting is overlapped with the tangent plane that grade inner port edge selects of opening to be processed；Pass through rotation
Measurement briquetting is fixed a number bolt；To measurement briquetting with opening grade endoporus while carrying out in perforate finishing, process
A grade diameter of bore is opened high pressure cylinder using inside micrometer to measure, and is required until measurement result is met.
The beneficial effects of the utility model carry out subsidiary when being shelves finishing of internal diameter split using measurement briquetting so that
The finishing scope of grade endoporus is opened more than 180 °, while inside micrometer easy to use is measured, can also reduce measurement
Error, meets the tolerance that steam turbine high-pressure cylinder opens grade endoporus；Clamping support it is simple in construction, manufacturing cost is low, is easy to big model
Enclose popularization；Clamping support to clamp position unrestricted, clamp conveniently.
