Embodiment Construction
[0059] To better explain the present invention, it will be described in detail by detail below with reference to the accompanying drawings.
[0060] Such as Figure 1 to 5 As shown, the present invention provides a registration device of a steam turbine holding ring, including the header registration device 1 and the end leaf registration device 2. The head leaf registration device 1 includes a first connecting plate 11 and a header measuring device connected to the header measuring device, the first connecting plate 11 for holding the upper half-seminated ring. The mid-bia surface is fixed, and the head leaf measuring device is used to measure the relative position of the head leaf root and the header of the semi-retired ring ring and the holding ring.
[0061] The end leaf registration device 2 includes a second connecting plate 21 and a terminal leaf measuring device, the second connecting plate 21 connected to the end of the leaflet, which is used in the middle of the lower sem...

The invention belongs to the technical field of steam turbine blade registration, and in particular relates to a registration device and method for a steam turbine ring-holding pre-twisted blade. A registration device for a ring-holding pre-twisted blade of a steam turbine provided by the present invention includes a first blade registration device and a last blade registration device. The first blade registration device includes a first connecting plate and a first blade measuring device. The leaf measuring device is connected, and the end leaf registration device includes a second connecting plate and the end leaf measuring device, and the second connecting plate is connected with the end leaf measuring device. The registration device for the ring-holding pre-twisted blade of the steam turbine solves the problem in the prior art that the amount of blade repair and removal cannot be determined efficiently and accurately during the assembly process of the stator blade.
Description
Technical field [0001] The present invention belongs to the field of steam turbine blade registration, and more particularly to a registration device and method of a steam turbine ring preceding blade. Background technique [0002] The static blasting ring is one of the main components of the steam turbine flow part. It is a multi-stage caliber carrier, an upper and lower half-injection structure; its blade is multi-strip-bearing compliance blade, T-type leaf root Arc positioning, oblique quadrangular damping belt, with pre-racing override on the backcar contact surface; the blade is loaded into the ring, the lower half of the leaf root contact, and adjacent blade leaves root contact The face is tight, and the strip is hurted and the sloppy blade is placed. At the same time, the surrounding belt causes the elasticity of the assembled torsion, and the inclined surface is slipped along its contact, and finally, the lower semicoprotic bolt is completed. Equipment. [0003] Usually, ...
