Abstract

The invention provides a measuring device for detecting the overall-length conical surface of a clapboard stator blade, capable of solving the problem that the middle position of the overall-length conical surface of the clapboard blade cannot be detected by current detection methods, the measuring device can accurately detect the overall-length plane size of the whole blade and has the advantages of simple structure, convenient and quick measurement, accurate and reliable measurement result. The measuring device comprises a base and is characterized in that two ends of the base are respectively provided with a big-head measurement base and a small-head measurement base, wherein the inner sides of the big-head measurement base and the small-head measurement base are respectively provided with a big-head molded surface locating plate and a small-head molded surface locating plate; an alignment base is arranged on the upper longitudinal edge of the base and between the small-head molded surface locating plate and the big-head molded surface locating plate; and an alignment apex is installed on the alignment base.

Description

Detect the measurement mechanism of the total long cone surface of diaphragm nozzle sheet
Technical field
The present invention relates to blade testing tool field, be specially a kind of measurement mechanism that detects the total long cone surface of diaphragm nozzle sheet.
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 invention provides the 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.
The measurement mechanism of the total long cone surface of detection diaphragm nozzle sheet of the present invention, it is simple in structure, can carry out accurately and efficiently measuring to the whole profile of blade concentric reducer easily.
