Summary: The article introduced aperture of connection of turbine rotor flange to use the treatment method that adjusts spacer to replace boring model, undertook comprehensive analysis to machining medium key, difficulty; And with machine a method formerly to undertake contrast, analyse the advantage of this method. 1 preface now the flange connection aperture of rotor of my plant turbine is to use boring model to undertake machining, but as me model of plant turbine unit is increasing, the boring model of admeasure workshop is increasing also, the boring model with frequent new addition also added very big workload to technology design. The article adjusts spacer to replace boring model to machine the process analysis of aperture of connection of turbine rotor flange through be being used to D600H low-pressure rotor, elaborated the process that this plan carries out, pass the test and verify of actual production, showed this rationality that machines plan, advantage. 2 traditions the treatment method of aperture of join of the flange between low-pressure rotor of A of 600 thousand aircrew, B pursues method of treatment of motion of aperture of join of the flange between 1 low-pressure rotor is gotten beforehand with jig adjust spacer connection aperture; spacer in flange of A low-pressure rotor dish go up, mount boring model (on boring model " A " the circle outside mark and rotor flange " A " number is right neat) , the flange connection aperture of boring A low-pressure rotor (1) seeing a picture; Get off boring model, boring model go up in B low-pressure rotor, beyond round " A " number is right neat, aperture of connection of flange of boring B low-pressure rotor. The tradition machines actor defect advantage of the method: With same the position that assured connection aperture spends an aperture of flange of boring model treatment; Defect: Technology design workload is big, increase rotor to machine tool to design a quantity. 3 jig was used when because all flange aperture that adjust spacer are getting my plant beforehand,using the treatment method that adjusts spacer to replace boring model, assured to adjust the position of spacer connection aperture, and adding what man-hour uses be same adjust spacer, because this is in theoretic can use the opening of rotor flange connection that adjusts spacer to replace boring model machine. The flange connection opening that plans working treatment to adjust spacer uses jig to machine the join aperture that adjusts spacer, make sure the position that adjusts spacer connection aperture spends contented blueprint requirement. Put gyro wheel support two bracket parallel is put and gyro wheel center connects a line to should agree with direction of boring machine main shaft, and preliminary adjustments two bracket gyro wheel, after making sure rotor is put on gyro wheel bracket, rotor center line is in horizontal position, adjust solid support base is tightened after ending. Put rotor to pursue 2 rotor are put put rotor to see a picture 2. Clean rotor journal, journal of the mount after besmear prevents rubiginous oil keeps jacket; Trice rotor, buy is put on gyro wheel bracket; With rotor of coarse adjustment of frame type gradienter, make be in horizontal position, allow is poor 0.

03; Censor cooperates to search with dial gauge rotor flange end panel and machine tool main shaft are perpendicular, requirement level and perpendicular direction allow are poor 0.

005(target cost is 0) . Graph 3 adjust spacer to install sketch map to pursue 4 adjust spacer pin Kong Jia is versed in Kong Jia of sketch map flange is versed in get flange connection aperture to press connection of rotor flange end panel beforehand position of Kong Hua line and craft requirement get connection bottom outlet beforehand; Installation adjusts spacer to adjust spacer to install sketch map to see a picture 3. Be in spacer outfit flange end panel (the directional) that notices to adjust spacer, right " A " mark, make on spacer beforehand bore should go up with flange beforehand bore is roughly right neat; Wear 4 screw 4-Ø60 aperture inside (aperture of connection hole bottom, all cloth) , bear nut gently; With dial gauge round outside adjusting spacer examination adjusts spacer and flange coaxial to spend, level and perpendicular direction all asked each at 2 o'clock dial gauge 0 - 0; When searching to adjusting spacer, allow to use jack fine tuning; Search hind close nut; Slide to prevent to adjust spacer, because this is in the plan should be pressed after close nut 4 deserve to get, Ø10 of bore with a reamer sells aperture and distribute pin; Attention: If adjust spacer to go up,the 2-Ø10 craft fixed position that already machined sells aperture, sell Kong Weiji to allow to drill the hole of 2-Ø10 in flange end panel with already having, an enlarge, bore with a reamer reachs unisonant whole spacer 2-Ø12, deserve to install fixed position to sell; If adjust spacer to go up to sell aperture without craft fixed position, show by attached drawing place undertake machining. Aperture of connection of treatment rotor flange allows aperture to machine aperture of rotor flange connection with adjusting the flange connection Kong Weiji of spacer. After finishing examination treatment is finished, the examination discovers aperture of rotor flange connection satisfies blueprint requirement completely. The 4 successes that use the advantage that adjusts spacer to replace boring model to be machined through trying, saying palpability to adjust spacer to replace the boring model that when rotor is machined, uses before is completely feasible, use adjust spacer treatment to be able to make sure position of opening of rotor flange connection spends a requirement likewise. Compare before technique, new technique reduced rotor tool to design, reduced cost. 5 ends pragmatics adjusts spacer to replace boring model to machine the treatment program of aperture of rotor flange connection, pass actual test and verify to be able to see, this technology program can accord with product blueprint requirement very well, it is certain to produce efficiency to also have rise, for me the factory added design of much program of new product technology to provide experience gradually later.
