Description
Technical field
The present invention relates to steam turbine field, is measured more particularly to the processing fitting rate in back arc lines face in a kind of assembling of blade
Method and technique segmental arc.
Background technology
Back of the body arc blade is widely used in key project steam turbine in assembling, because turbine blade fitting surface is changed by facing directly
For interior, back arc lines face, adjacent two blade contact faces are increased, security during blade operation is improved, but adds to blade
Work brings difficulty.Blade requires adjacent two blade contact areas up to more than 70% when assembling, and existing interior back of the body arc structure
Blade blade fitting rate in assembling is only capable of reaching 30% or so, to meet blade matching requirements, during assembling pincers worker need a large amount of
Reconditioning works, and every blade reconditioning quality reaches 0.2mm-0.3mm when most, and assembly period is longer.Because blade uniformity is poor, often
Blade reconditioning quality is not quite identical, and blade throat dimension size is uneven, and very big negative effect is caused to leaf quality.
By analyzing the problem of existing process is present：(1) molded line that back arc lines processing uses in existing blade assembling
Milling cutter cutting edge extends back, and area is big (as shown in Figure 3 and Figure 4), and molded line milling cutter is measured plate using milling cutter, and measurement accuracy is
0.03mm, molded line milling cutter machining accuracy are low；(2) blade is processed using plain-milling machine, during processing hanger from cutter farther out, lathe master
Axle rigidity is inadequate, is easily produced when going out knife and allows knife；(3) there is no special tooling when measuring blade fitting rate, assemble interior back of the body arc measurement
When the free degree it is larger, measuring state with assembling when measuring state have difference.Pincers worker reconditioning quality is big when causing the blade to assemble, assembling
Cycle is grown.Every blade reconditioning is inconsistent, and throat dimension is inconsistent when ultimately resulting in blade assembling, and then influences the dress of steam turbine
With quality.
It is total described, in existing blade assembling back arc lines processing it is low to there is machining accuracy, easily left after processing and allow knife
The problem of pincers worker reconditioning quality is big, and assembly period is long be present when trace, influenceing fitting rate, and assembling.
The content of the invention
The invention aims to solve low, the processing that machining accuracy be present of back arc lines processing in the assembling of existing blade
Easily leave afterwards and allow tool marks, the problem of pincers worker reconditioning quality is big, and assembly period is long when influenceing fitting rate, and assembling be present, and then provide
The processing fitting rate measuring method and technique segmental arc in back arc lines face in a kind of blade assembling.
The technical scheme is that：
The processing fitting rate measuring method in back arc lines face, the processing method include following step in a kind of blade assembling
Suddenly,
Step 1: rough mill in blade assembling, back arc lines face：
Interior, back arc lines face is assembled to blade using milling cutter and carries out rough milling, speed of mainshaft 30rpm-50rpm, is entered
It is 30mm/min-50mm/min, cutting depth 2mm-5mm, allowance 0.3mm-0.4mm to amount；
Step 2: the assembling of first time finish-milling blade is interior, back arc lines face：
Interior, back arc lines face is assembled to blade using milling cutter and carries out first time finish-milling processing, first time finish-milling blade is to walk
Knife is processed, speed of mainshaft 30rpm-50rpm, amount of feeding 40mm/min-60mm/min, cutting depth 0.3mm；
Step 3: second of finish-milling blade assembling is interior, back arc lines face：
Interior, back arc lines face is assembled to blade using milling cutter and carries out second of finish-milling processing, second of finish-milling blade is light
Knife is processed, speed of mainshaft 120rpm-150rpm, amount of feeding 90mm/min-120mm/min, cutting depth 0.05mm-
0.1mm；
Step 4: measurement blade assembling is interior, the fitting rate of back of the body arc：
Technique segmental arc can be put into eight blades simultaneously, be uniformly coated with clearance permit powder in each blade concavity to be measured first, will
First blade is suitable from the bottom to top by remaining seven blades successively to assemble inner arc location and installation in the bottom of technique segmental arc
It is secondary to be arranged in technique segmental arc, uppermost blade assembling back of the body arc is gently tapped with copper rod, makes each blade assembling inner arc and phase
Adjacent blade assembling back of the body arc fully contacts, and then takes out blade successively, and range estimation blade assembling back of the body arc red lead powder stained area accounts for assembling
Arc gross area percentage is carried on the back, as blade assembling is interior, carries on the back the fitting rate of arc；
Step 5: calculate in blade assembling, the fitting rate of back of the body arc：
To eliminate the error that nethermost blade concavity positioning belt comes, five blades are only taken to calculate measurement result, it is bottom
Two blades colour as reference data, topmost a blade without red lead powder, if blade assembling is interior, the fitting rate of back of the body arc is big
In 50%, blade can continue to process；If blade assembling is interior, the fitting rate of back of the body arc is less than 50%, the molded line part of milling cutter is entered
The overall relief grinding of row or part relief grinding, repeat step one to step 5 until in blade assembling, the fitting rate of back of the body arc be more than 50%, it is complete
The measurement of interior, back of the body arc fitting rate is assembled into blade.
Further, the first time finish-milling blade in step 2 and second of finish-milling blade are upmilling.
Further, the speed of mainshaft in step 1 is 40rpm, amount of feeding 40mm/min, cutting depth 4mm, is added
Spare time amount is 0.4mm.
Further, the speed of mainshaft in step 2 is 40rpm, amount of feeding 50mm/min, cutting depth 0.3mm.
Further, the speed of mainshaft in step 3 is 140rpm, amount of feeding 110mm/min, and cutting depth is
0.1mm。
Further, Step 1: the milling cutter in step 2 or step 3 is back of tooth step milling cutter, back of tooth step milling
Interior back arc lines are processed on knife.
The technique segmental arc of the fitting rate measurement in back arc lines face in a kind of blade assembling, it includes measurer body, molded line positions
Block and eight blade root Top fastening screws,
The side of measurer body upper surface processes T-shaped locating slot, and the both sides of T-shaped locating slot process two boss, T-shaped locating slot
Coordinate with the blade root of blade, the opposite side processing groove of measurer body upper surface, groove is oppositely arranged with T-shaped locating slot, groove and T
Amount between type locating slot particularly vertically from top to bottom sequentially processes eight screwed holes, and molded line locating piece is fixedly mounted
In the bottom of the specific T-shaped locating slot of amount, eight blade root Top fastening screws are respectively in specific eight screwed holes of the amount of being inserted into,
Further, the upper surface processing arcuate structure of molded line locating piece.
Further, the end face for measuring specific opposite side processing groove is curved end.
Further, it also includes multiple connecting pins, and molded line locating piece is affixed by multiple connecting pins and measurer body.
The present invention has the following effects that compared with prior art：
1st, the present invention assembles interior, back arc lines face using back of tooth step milling cutter to blade 3 and rough milled, for the first time successively
Finish-milling and second of finish-milling processing, back of tooth step milling cutter detect tool precision using 20 times of enlarged drawings, its profile tolerance are improved
To 0.01mm.The present invention is effectively improved blade 3 and assembles the interior, machining accuracy in back arc lines face by optimizing cutter structure.
2nd, first time finish-milling blade of the invention assembling is interior, back arc lines face and second of finish-milling blade assembling are interior, back of the body arc
