Device fabrication company is widely used.
Honeycomb seal is mainly made up of sealing matrix and the soldering ring-type cellular sandwich in substrate ring.Ring-type cellular sandwich
Before vacuum brazing is in substrate ring, certain fixing welding method need to be used to be fixed with matrix by ring-type cellular sandwich
Connect as one, to ensure the mutual alignment between containment member and dimension precision requirement after soldering.Prior art is usual
The method of attachment that is welded and fixed used has the methods such as argon tungsten-arc welding, electric resistance welding, special brazing tooling.Ring-type honeycomb presss from both sides
Core is to be made up of the curved circle of cellular band, and cellular band is made up through molding, some postwelding of the foil of thickness 0.076mm.
Ring-type cellular sandwich by the curved circle of cellular band looped during, honeycomb ceramics thickness then in causing due to ring internal diameter pressurized
Increasing, ring external diameter tension causes outer honeycomb ceramics thickness then to reduce, from the point of view of the cross section of ring-type cellular sandwich, similar
One trapezium structure.The diameter of ring-type cellular sandwich is the least, and gradient is the biggest, and tack welding size is the poorest, ultimately results in zero
Part is scrapped.For diameter at the minor diameter honeycomb seal of Φ 50～100mm scope, because ring-type cellular sandwich poor location is led
The honeycomb seal scrappage caused is up to more than 50%, and production cost remains high, and is of manufacturing enterprise's urgent need solution
Technical problem.
Summary of the invention
The ring-type cellular sandwich of minor diameter honeycomb seal for prior art positions the problem existed, purpose of the present invention purport
One is being provided to be applicable to minor diameter honeycomb seal honeycomb resistance tack welding limiting tool, to reduce because of honeycomb texture itself
The dimensional accuracy of the gradients affect resistance tack welding produced, thus improve the size of minor diameter honeycomb seal structure tack welding
Precision.
What the present invention provided is applicable to minor diameter honeycomb seal assembling resistance tack welding limiting tool, and its composition includes ring
Shape cellular sandwich is limited in, from one end, the positioning seat sealed in matrix pilot hole, and ring-type cellular sandwich is spacing from the other end
The pressure ring of one end in sealing matrix pilot hole, for compressing the card orchid assembly of positioning seat and pressure ring, described positioning seat sets
In respect of respectively with ring-type cellular sandwich one end and seal matrix pilot hole end face phase separation seam, the height of seam is ring
Shape cellular sandwich is limited in and seals the degree of depth of one end in matrix pilot hole, and the ring height of described pressure ring presss from both sides not less than ring-type honeycomb
Core is defined in and seals the degree of depth of the other end in matrix pilot hole, and described card orchid assembly is arranged on by framework with by screw thread pair
The screw that compresses on framework is constituted, and described framework is the rectangle cassette framework of designed openings, is arranged on opening side

In technique scheme of the present invention, described frame openings preferentially uses asymmetric openings, the mouth end of opening
For the termination of side frame support body, the fracture that another side mouth end is opening place frame body of opening.
In technique scheme of the present invention, preferably using constitute opening frame body fracture as composition compress positioning seat,
Ring-type cellular sandwich and compressing of pressure ring compress structure described in pair.
In technique scheme of the present invention, compressing screw for compress positioning seat, its axis is preferably located at and is arranged on
Compressing between screw axis and opening place frame body on opposite side frame body.
In technique scheme of the present invention, the seam of described positioning seat is paid the utmost attention to be designed as tapered seam, with seam
Tapered end compresses ring-type cellular sandwich end face.
In technique scheme of the present invention, the ring thickness of described pressure ring is not more than ring thickness and the frame body of ring-type cellular sandwich
Wall thickness, generally no greater than 20mm.Positioning seat and pressure ring can be fabricated to by bakelite, nylon or polytetrafluoroethylmaterial material.
In technique scheme of the present invention, described mortgage screw is preferably devised with turn-knob termination.
The minor diameter honeycomb seal that is applicable to using the present invention to provide assembles resistance tack welding limiting tool, to minor diameter
Honeycomb seal assembling carries out resistance tack welding, can efficiently reduce in the process being circularized cellular sandwich by the curved circle of cellular band
In cause due to ring internal diameter pressurized in honeycomb ceramics thickness then increase, ring external diameter tension causes outer honeycomb ceramics thickness the most then to subtract
Little produced trapezoidal distortion, substantially increases the dimensional accuracy of minor diameter honeycomb seal tack welding, reduces because of ring-type
The honeycomb seal scrappage that cellular sandwich poor location causes, and then reduce production cost.Applicant is being provided without this
Minor diameter honeycomb seal is assembled, at ring-type cellular sandwich at vacuum pricker by the resistance tack welding limiting tool of bright offer
Resistance tack welding is carried out, owing to ring-type cellular sandwich trapezoidal distortion spends the scrappage caused greatly before in being welded in substrate ring
The highest, once occurred that continuous faulty part quantity was up to 11.Use present invention offer is applicable to minor diameter honeybee
After nest seals assembling resistance tack welding limiting tool, the honeycomb seal assembling resistance tack welding of minor diameter, honeycomb seal is fixed
The dimensional accuracy of position weldering is greatly improved, and a soldering qualification rate is up to more than 96%.
The present invention provide be applicable to minor diameter honeycomb seal assembling resistance tack welding limiting tool, sum up have with
Under useful technique effect effect:
1, match due to the locating dimension of limiting tool grinding final with part honeycomb size, solve honeycomb texture
The gradient deformation problem itself carried, ensures that its location dimension meets matching requirements.
