Fig. 2 is the structural schematic diagram of the welding main body of blade weld assembly in Fig. 1；
Fig. 3 is the cross-sectional view that the mounting hole of main body is welded in Fig. 2.
Specific embodiment
The object of the present invention is to provide the nozzle rings that one kind can reduce blade weld assembly frictionally damage, prolong the service life
Component.
Please refer to Fig. 1, Fig. 2, a kind of nozzle ring assemblies of the invention comprising blade weld assembly 1 is set in blade weldering
Shifting disc 2 on connected components 1 and the backing plate 3 being installed under blade weld assembly 1.
Referring to Fig. 1, Fig. 2, blade weld assembly 1 includes welding main body 11, the circle first in 11 center of welding main body
Hollow-out parts 12, are opened in the mounting hole 14 welded in main body 11, solid at the boss 13 to be formed that raises upward from welding 11 upper end of main body
Due to several actively shift forks 15 in mounting hole 14 and it is installed on several blades 16 of welding 11 lower end of main body, and the present embodiment
Middle actively shift fork 15 and blade 16 are equipped with 10, can change corresponding number according to practical situation in other embodiments.It is described
Welding 11 lower end of main body opens up that there are five the fixing grooves 17 that are recessed inwardly, and fixing groove 17 is located on the outside of mounting hole 14.The peace
Filling hole 14 includes upper hole 18 and the next hole 19 below upper hole 18, and the upper hole 18 is penetrated through with the next hole 19
It is distributed in welding main body 11, and 18 internal diameter of upper hole is greater than 19 internal diameter of the next hole.
2 upper end of shifting disc is uniformly provided with several U-shaped first card slots 21, and the first card slot 21 is equipped with 10 in the present embodiment,
And the first card slot 21 it is several set with the number of actively shift fork 15 as reference.One the is wherein opened up between two first card slots 21 again
Two draw-in groove 22.
If backing plate 3 include circular second hollow-out parts 31, the round first through hole 32 of five on backing plate 3 perforations and
The second circular through hole 33 is done, 33 numbers of the second circular through hole are identical as 16 numbers of blade in the present embodiment.
Shifting disc 2 is socketed in 1 one side end of blade weld assembly, and the actively shift fork 15 on blade weld assembly 1 assigns into
In first card slot 21 of shifting disc 2.Connecting rod 161 is welded on the blade 16, one end of connecting rod 161 passes through welding main body
11 mounting hole 14 and one end of actively shift fork 15 rivet, and enhance synchronism when blade 16 and the rotation of actively shift fork 15, institute
Being housed in the upper hole 18 of mounting hole 14 for connecting rod 161 is stated, since upper 18 internal diameter of hole is greater than 19 internal diameter of the next hole,
