Background technology
Low pressure second last stage blade in steam-turbine unit is provided with lacing wire boss, and this lacing wire boss is in order to ensure that blade is contained in
The stability rotated under spacing between rotor blade and duty, during blade processing, lacing wire land length direction is all
Leave surplus, for the first time with rotor trial assembly time, ensure that the spacing of whole circle blade is uniform, measure every blade lacing boss processing
Surplus, more above boring machine is processed surplus, owing to blade construction is irregular, clamping difficulty.Existing processing lacing wire boss
Clamping device be with a L-type ferropexy on platen, blade is leaned against LXing Tie corner and mixes up position, blade top
Portion's pressing plate, screw rod etc. are pushed down, and this fixed form does not has blade installing plate, artificially puts by lathe centering lacing wire end face position
Put.
Summary of the invention
The present invention is solid for solving existing low pressure second last stage blade lacing wire boss Boring machine processing clamping device employing L-type ferrum
Being scheduled on platen, put by lathe centering lacing wire endface position, it is big to there is correct error in this installation way, and clamping takes
The problem of thing, and a kind of supercritical gas-turbine low-pressure last stage blade lacing wire boss Boring machine processing clamping device is provided.
The present invention solves that above-mentioned technical problem adopts the technical scheme that:
The supercritical gas-turbine low-pressure last stage blade lacing wire boss Boring machine processing clamping device of the present invention include supporter,
Blade installing plate, the first bolt, the second bolt and four the 3rd bolts, supporter is made up of substrate, L shaped plate and top board, top board,
L shaped plate and substrate from top to bottom set gradually and are formed integrally, and each side of substrate is provided with two U-type groove, the side of L shaped plate
Plate face is provided with side tapped through hole, and top board is provided with tapped through hole, and the upper surface of blade installing plate is provided with mate with blade oblique
Line style blade root slot, described blade installing plate is arranged on the upper surface of substrate and is positioned at the inner side of L shaped plate, blade installing plate and substrate
Being connected by four the 3rd bolts, the first bolt is threadeded with upper tapped through hole, and the second bolt is with side tapped through hole screw thread even
Connect.
The present invention compared with prior art has the effect that
One, the clamping device utilizing the present invention carries out clamping to blade, and clamping is easy, compares employing L-type ferropexy blade
Correct error decreases more than 80%, the most error free, overcomes a difficult problem for blade construction irregularly difficult clamping.
Two, present configuration is simple, manufactures easily, low cost, it is simple to use on a large scale.

Detailed description of the invention
Detailed description of the invention one: combine Fig. 1～Fig. 5 and illustrate that present embodiment, present embodiment include supporter 1, blade
Installing plate the 2, first bolt the 3, second bolt 4 and four the 3rd bolts 5, supporter 1 is by substrate 1-1, L shaped plate 1-2 and top board 1-3
Forming, top board 1-3, L shaped plate 1-2 and substrate 1-1 from top to bottom set gradually and are formed integrally, and each side of substrate 1-1 sets
Having two U-type groove 1-1-1 (eight U-type groove altogether), the side plate face of L shaped plate 1-2 is provided with side tapped through hole 1-2-1, top board 1-3
Being provided with tapped through hole 1-3-1, the upper surface of blade installing plate 2 is provided with the bias type blade root slot 2-1 mated with blade, described
Blade installing plate 2 is arranged on the upper surface of substrate 1-1 and is positioned at the inner side of L shaped plate 1-2, and blade installing plate 2 passes through with substrate 1-1
Four the 3rd bolts 5 connect, and the first bolt 3 is threadeded with upper tapped through hole 1-3-1, the second bolt 4 and side tapped through hole 1-
2-1 is threaded.
Detailed description of the invention two: combine Fig. 4 and Fig. 5 and present embodiment is described, the upper surface of the substrate 1-1 of present embodiment
Be provided with the tapped blind hole 1-1-2 of four quadrate arrays along corner, blade installing plate 2 is provided with and four tapped blind hole 1-1-2
The most just to installing plate tapped through hole 2-2.Other composition and annexation are identical with detailed description of the invention one.
The installation method of back of the body arc lacing wire boss processing: U-type groove 1-1-1 on substrate 1-1 and platen by bolt,
Nut fastens, by the back of the body arc of bias type blade root slot 2-1 outwardly to main spindle's, with four the 3rd bolts 5 by blade installing plate 2 and
Substrate 1-1 fastens, and is inserted along bias type blade root slot 2-1 by the blade root 8 of blade 6, until the side of bias type blade root 8 is attached to L-shaped
On plate 1-2, then by the first bolt 3 through upper tapped through hole 1-3-1, hold out against at the integral shroud of blade 6 by the revolving force of screw thread,
After again by the second bolt 4 through side tapped through hole 1-2-1, hold out against blade lacing boss inner arc side 10 by the revolving force of screw thread,
Thus can be with the lacing wire boss of machining back arc side.
The installation method of inner arc lacing wire boss processing: first pull down the low pressure blade 6 processing back of the body arc lacing wire boss, by oblique line
The blade root 8 of blade 6 to main spindle's, is inserted, to bias type by the inner arc of type blade root slot 2-1 outwardly along bias type blade root slot 2-1
The side of blade root 8 is attached in L shaped plate 1-2 (carry on the back lacing wire head after arc inserts with inner arc can pass through along oblique trunking site error with screw 4
Adjust at shimming herein, it is ensured that hold out against screw 4 consistent with lacing wire head position degree), then by the first bolt 3 through upper tapped through hole
1-3-1, holds out against at the integral shroud of blade 6 by the revolving force of screw thread, the most again by the second bolt 4 through side tapped through hole 1-2-1,
Held out against the lacing wire boss back of the body arc side 9 of blade by the revolving force of screw thread, thus can process the lacing wire boss of inner arc side.
