Embodiment Construction

[0018] See figure 1 , figure 2 and image 3 , the present invention comprises a bottom plate 10, on which a blade positioning device, a blade tightening device, and a blade measuring template assembly are arranged, and a plurality of transverse key grooves 11 and longitudinal key grooves 12 perpendicular to each other and cross-connected are evenly distributed on the bottom plate 10, so that A grid-shaped keyway structure is formed on the bottom plate 10, and the blade positioning device, blade tightening device and blade measuring sample assembly are connected and positioned with the horizontal key groove 11 and the longitudinal key groove inner 12 on the bottom plate 10 through positioning keys 13, respectively.

[0019] Preferably, equal intervals are provided between adjacent horizontal keyways and between adjacent longitudinal keyways.

[0020] Preferably, the distance d1 between adjacent transverse keyways is equal to the distance d2 between adjacent longitudinal keyw...

Abstract

The invention provides a universal type steam turbine diaphragm stator blade total length measuring device, which can solve the problems of poor universality and high tooling cost of the existing steam turbine diaphragm stator blade total length measuring device. The universal type steam turbine diaphragm stator blade total length measuring device comprises a bottom plate, wherein a blade positioning device, a blade jacking device and a blade measuring template assembly are arranged on the bottom plate, a plurality of transverse keyways and longitudinal keyways which are perpendicular to one another and in cross connection are formed in the bottom plate uniformly, thus a latticed keyway structure is formed on the bottom plate, and the blade positioning device, the blade jacking device and the blade measuring template assembly are connected with the transverse keyways and the longitudinal keyways by means of positioning keys.

Description

technical field [0001] The invention relates to the field of blade processing and detection, in particular to a general-purpose measuring tool for the overall length of stationary blades of diaphragms of steam turbines. Background technique [0002] Most of the existing measuring tools for the overall length of the static blades of the steam turbine diaphragm are positioned by the blade profile and the inlet edge, and the axial direction is measured based on the profile line. Since the processing and production of the stator blades of the steam turbine diaphragm has the characteristics of many varieties and small batches, it is necessary to design and assemble the corresponding overall length measuring tools for different sizes of the steam turbine diaphragm stator blades, which leads to poor versatility of the overall length measuring tools , The problem of high cost of tooling. Contents of the invention [0003] In view of the above problems, the present invention provi...
