Description
Technical field
It is the present invention relates to a kind of clamp art, in particular to a kind of to improve certain and obturage ring assemblies class part soldering clamping
The clamp structure of precision.
Background technique
The component honeycomb ring sheet-metal formed that certain obturages ring assemblies class part is bad, and circularity is inadequate, obturages outer ring with core
Be bonded bad, when soldering assembly before is to need artificial school shape that can just install, easily lead to when positioning is welded surely since stress is big and
Problem in spot welding not.
Summary of the invention
In order to solve the above technical problems, certain obturages ring assemblies class part soldering dress the object of the present invention is to provide a kind of raising
The clamp structure of precision is pressed from both sides, specific technical solution is as follows:
It is a kind of to improve certain clamp structure for obturaging ring assemblies class part soldering clamping precision, including pedestal, expansion block, guiding
Block, cone, voussoir, mandrel, screw and handle；
The pedestal is in boss shape, and lower end installs side both ends and is equipped with handle, and raised head face is laid with groove, sets in groove
There is threaded hole, boss center is equipped with mandrel mounting hole；
The mandrel is fixed in the mandrel mounting hole at boss center；
The cone is socketed on mandrel；
The expansion block is fan-shaped, and one end is bonded with the taper-face contact of cone, and one end bottom side is equipped with step and part is bonded, in
The heart is provided with strip grooves；
The expansion block is placed on the groove upper end of pedestal, and is stuck on base boss at step；
The guide pad is T-shaped, across expansion block strip grooves be plugged on pedestal groove on, fixed by screw, and swollen
Block can slide on guide pad；
Expansion block tensioner part is passed downwardly through by cone, voussoir is compressed cone by the hole in mandrel.
It is described it is a kind of improve certain clamp structure for obturaging ring assemblies class part soldering clamping precision, preferred embodiment is institute
The boss for stating chassis is hollow structure, and uniformly distributed four mouths, are used for loss of weight and mounting screw below groove.
It is described it is a kind of improve certain clamp structure for obturaging ring assemblies class part soldering clamping precision, preferred embodiment is institute
The taper for stating cone is 20 °.
It is described it is a kind of improve certain clamp structure for obturaging ring assemblies class part soldering clamping precision, preferred embodiment is institute
The material that pedestal uses is stated as Cr25Ni20, the material that expansion block, guide pad, cone, mandrel and voussoir use is GH4169.
A kind of course of work improving the clamp structure that certain obturages ring assemblies class part soldering clamping precision: zero will be processed
Part is attached on chassis, is first shifted four expansion blocks onto recline with honeycomb ring position, is refilled upper cone, voussoir is squeezed into the slot of mandrel
In, until part is swollen to position, it checks that honeycomb ring and core obturage outer ring and whether closely to recline, furnace weldering is reentered after composite demand
It connects.
Beneficial effects of the present invention: honeycomb ring may be implemented in technical solution of the present invention and core obturages the accurate fixed of outer ring
Position, to reach the precision for improving assembly soldering.This fixture is applied at the scene, after a tooling is improved, work
Dress has been able to the requirement for meeting technique, the assembly precision before not only ensure that welding, also improves honeycomb ring and outer ring is brazed
Precision afterwards.
Detailed description of the invention
Fig. 1 is that core obturages outer ring and honeycomb boxing connects schematic diagram；
Fig. 2 is chassis structure schematic diagram；
Fig. 3 is that mandrel and cone cooperate schematic diagram；
Fig. 4 improves certain clamp structure schematic diagram for obturaging ring assemblies class part soldering clamping precision to be a kind of；
Fig. 5 is the cross-sectional view of Fig. 4.
In figure, the chassis 1-, 2- groove, 3- expansion block, 4- guide pad, 5- cone, 6- voussoir, 7- mandrel, 8- screw, 9- handle
Hand, 10- mandrel mounting hole, 11- core obturage outer ring, 12- honeycomb ring.
Specific embodiment
The part as shown in Figs. 1-5 belongs to annular welds fitting, and internal diameter only has 200mm, and internal honeycomb ring passes through high temperature pricker
Weldering is obturaged outer ring with core and is welded together.Since component is that lower mouth is small, big structure suitable for reading, therefore to consider that expansion block receives most
Part is loaded onto after small, receives the limitation of the size of internal diameter, if wanting that honeycomb ring is made to keep fitting closely with outer ring, one kind is needed to mention
It is high certain obturage the clamp structure of ring assemblies class part soldering clamping precision, including pedestal 1, expansion block 3, guide pad 4, cone 5, voussoir
6, mandrel 7, screw 8 and handle 9；
The pedestal 1 is in boss shape, and lower end installs side both ends and is equipped with handle 9, and raised head face is laid with groove 2, groove 2
In be equipped with threaded hole, boss center be equipped with mandrel mounting hole 10；
The mandrel 7 is fixed in the mandrel mounting hole 10 at boss center；
The cone 5 is socketed in mandrel 7；
The expansion block 3 is fan-shaped, and one end is bonded with the taper-face contact of cone 5, and one end bottom side is equipped with step and part is bonded,
Center is provided with strip grooves；
The expansion block 3 is placed on 2 upper end of groove of pedestal 1, and is stuck on 1 boss of pedestal at step；
The guide pad 4 is T-shaped, across expansion block 3 strip grooves be plugged on pedestal 1 groove 2 on, it is fixed by screw 8,
And expansion block 3 can be slided on guide pad 4；
Due to carrying out in high temperature furnace, helicitic texture cannot be used, therefore 3 tensioner zero of expansion block is passed downwardly through by cone 5
Cone 5 is compressed voussoir 6 by the hole in mandrel 7 by part.
The boss on the chassis 1 is hollow structure, and uniformly distributed four mouths, are used for loss of weight and mounting screw 8 below groove 2.
The taper of the cone 5 is 20 °.
For Cr25Ni20, expansion block 3, guide pad 4, cone 5, mandrel 7 and voussoir 6 use the material that the pedestal 1 uses
Material is GH4169.
A kind of course of work improving the clamp structure that certain obturages ring assemblies class part soldering clamping precision: zero will be processed
Part is attached on chassis 1, is first shifted four expansion blocks 3 onto recline with honeycomb ring position, is refilled upper cone 5, and voussoir 6 is squeezed into mandrel
In 7 slot, until part is swollen to position, check that whether closely, after composite demand again honeycomb ring and core obturage outer ring and recline
Enter furnace welding.
