Abstract
The utility model provides a measuring device for measuring the total long conical surface of a diaphragm stationary blade and can solve the problem that the middle position of the total long conical surface of the diaphragm stationary blade cannot be measured in the present measuring method. The measuring device can be used for accurately measuring the size of the total long conical surface of the whole blade, and has the advantages of simple structure, convenience in measurement and accurate and reliable measurement structure. The measuring device comprises a base and is characterized in that a large-head measuring seat and a small-head measuring seat are installed at both ends of the base, wherein a large-head molding surface positioning plate and a small-head molding surface positioning plate are installed on the inner sides of the large-head measuring seat and the small-head measuring seat respectively, an aligning seat is arranged among the longitudinal upper edge of the base, the large-head molding surface positioning plate and the small-head molding surface positioning plate, and an aligning top tip is installed on the aligning seat.
Description
Technical field
The utility model relates to blade testing tool field, is specially a kind of measurement mechanism that detects the total long cone surface of diaphragm nozzle.
Background technology
Along with the continuous development of blade designing technique, the manufacturing accuracy of diaphragm nozzle sheet concentric reducer length overall face requires more and more higher, and the matching requirements of diaphragm nozzle are also more and more higher.Some traditional measurement methods commonly used can not satisfy its accuracy requirement far away.At present, measurement for the total long cone surface of diaphragm nozzle sheet, it is to be that the lagging edge model that advances of 6mm detects the concentric reducer length overall face of diaphragm nozzle sheet by two thickness, its total long cone surface centre position can't be detected with model, so it can not accurately detect the size of whole length overall face, the gap of length overall face is inhomogeneous when causing blade to be assembled on the dividing plate.
Summary of the invention
At the problems referred to above, the utility model provides a kind of measurement mechanism that detects the total long cone surface of diaphragm nozzle sheet, it can solve the problem that present detection method can't detect total long cone surface centre position of dividing plate blade, can prepare to detect whole blade length overall face size, simple in structure, it is convenient to measure, and measurement structure accurately and reliably.
Its technical scheme is such, it comprises base, it is characterized in that: described base two ends are separately installed with major part measuring seat and microcephaly's measuring seat, described major part measuring seat and microcephaly's measuring seat inboard are separately installed with major part profile location-plate and microcephaly's profile location-plate, be equipped with the line seat between the vertical coboundary of described base, described major part profile location-plate and the microcephaly's profile location-plate, described top to being equipped with line on the line seat.
It is further characterized in that: described microcephaly's measuring seat is installed on microcephaly's measuring seat locating piece; Described microcephaly's measuring seat locating piece is installed on described base; On described major part profile location-plate and the microcephaly's profile location-plate blade steam admission side register pin is installed all.
A kind of measurement mechanism that detects the total long cone surface of diaphragm nozzle sheet of the present utility model, it is simple in structure, can carry out accurately and efficiently measuring to the whole profile of blade concentric reducer easily.
