Description
Technical field
The present invention relates to aero-engine technical field of auxiliary equipment, especially a kind of support case component vacuum brazing is used
Tooling and its application method.
Background technique
Engine is aircraft " heart ", be push aircraft fast development motive power, be aeroplane performance, reliability and at
This deciding factor, the development of aero engine technology have extremely important effect to national defence and national economy, it every
Primary breakthrough and progress all indicate the mankind's soaring again in aviation field；Casing be aero-engine important part it
One, it is the pedestal of entire engine, is the main load component in aero-engine, and contour structures are complicated, different hairs
Motivation, engine different parts, casing shape is different, and the function of casing part determines the shape of casing, but they
Essential characteristic be cylinder-shaped or cone shell and supporting plate composition component.
In the prior art, the support case component of certain aero-engine is the core component on engine, wherein load
Casing 8 is integrally formed without surplus hot investment casting using K418 high temperature alloy, is complicated thin-section casting, support case dress
Vacuum brazing is welded after timing needs carve type cooperation by the conical surface with bearing block 9, and structure is as depicted in figs. 1 and 2, due to
Vacuum brazing is a kind of using solder thawing (workpiece is non-fusible), and the solder of melting is sucked and filled by liquid capillarity
Between full two solid workpieces, a kind of welding method of welding point is formed after condensation, so between matching before the welding method butt welding
Gap is more demanding, and clearance requirement is generally between 0.05-0.1mm, i.e., between 8 inner wall of 9 outer wall of bearing block and support case between
For gap between 0.05-0.1mm, gap is too small or excessive, and liquid capillary phenomenon can weaken, and influence quality of vacuum brazing；Soldering
Welding line joint 91 is formed in the contact surface of 9 outer wall of bearing block and 8 inner wall of support case after the completion, to guarantee subsequent assembly matter
After the completion of amount, bearing block 9 and support case 8 weld, it is desirable that 9 bottom anchor ring of bearing block to the distance between 8 bottom surface of support case L
For 20 ± 0.1mm, however since 9 basis material of bearing block is 1Cr17Ni2 stainless steel, 8 basis material of support case is that K418 is cast
Part, the two thermal expansion coefficient is different, and wherein K418 thermal expansion coefficient is slightly above 1Cr17Ni2, causes support case 8 in vacuum pricker
Expansion ratio bearing block 9 is big when weldering, if do not constrained its axial position, axial float can be generated, so that postwelding bearing block 9
Bottom anchor ring is overproof to the distance between 8 bottom surface of support case L dimension, is unable to satisfy subsequent matching requirements.
