Big shoulder locating piece 10 is fixed on the front end face of frame 6 by the cooperation of waist typed through hole 103 and outer-hexagonal bolt 11.Due to forked type
14 precision prescribed of blade is high, and is assembled using the big shoulder face of forked type blade 14 as benchmark face when assembly, therefore fixed with the big shoulder of root
Positioning datum when position block 10 is processed as forked type blade 14 on length direction.
Further, as shown in figure 17, it is equipped with and prolongs to the left along its width direction in the front end face for carrying on the back radial flute profile cushion block 12
End is stretched, double convex nipper 121 is equipped on the front end face of elongated end, radial flute profile cushion block 12 is carried on the back and is used to auxiliary positioning forked type leaf
The root cap of piece 14 carries on the back radial direction, and double 121 part of convex nipper can offset the stress generated when processing, prevent forked type blade 14
The deformation of rooted tooth type, while avoiding generating blade root vibration when interfering and process forked type blade 14 with process tool and blade root is caused
It influences.It carries on the back soket head cap screw 2 of the radial direction flute profile cushion block 12 by screwing on frame 6 to it to exert a force to forked type blade 14, make
The radial flute profile cushion block 12 of back plays the role of support to forked type blade 14 and steps up with stress, thus the root cap of fixed forked type blade 14
And flute profile.
Further, as shown in Figure 6 and Figure 7, spaced lug there are two being set on the side end face that frame 6 is open
4, the cover board 5 is rotatablely connected by straight pin 3 and lug 4, can be real after cover board 5 is closed with frame 6 by outer-hexagonal bolt 11
The totally-enclosed clamping of existing forked type blade 14.
The course of work:
When installing and using, it will first carry on the back radial flute profile cushion block 12 and be mounted between retention bead 61 and the side wall of frame 6, then
Steam output side cushion block 7 is mounted on to the left side for carrying on the back radial flute profile cushion block 12, the big shoulder locating piece 10 of blade root is passed through into outer-hexagonal bolt 11
It is fixed on frame 6, then the big shoulder of forked type blade 14 and the limited block 102 on the big shoulder locating piece 10 of blade root is adjacent to, make blade root
Positioned at 6 outside of frame, steam admission side cushion block 9 is placed on forked type blade 14, flute profile compact heap 8 is mounted on steam output side cushion block 7
On, finally by cover board 5 be closed after, respectively by the jackscrew 13 cooperated on cover board 5 with flute profile compact heap 8, frame 6 with steam admission side pad
Soket head cap screw 2 that block 9 cooperates is screwed with the soket head cap screw 2 for carrying on the back radial 12 cooperation of flute profile cushion block on frame 6, makes to pitch
Interior radial, the back radial direction of the root cap of type blade 14, steam admission side, steam output side direction are under pressure in frame type clamp.
The preferable specific embodiment of the above, only the utility model, these specific embodiments are all based on this
Different implementations under utility model general idea, and the protection scope of the utility model is not limited thereto, it is any ripe
