Description
Technical field
This utility model relates to a kind of turning adjusting sleeve, more particularly, it relates to heat exchange list in a kind of HTGR
The turning adjusting sleeve of cartridge module in unit.
Background technology
HTGR belongs to forth generation nuclear reactor technology, Shidao Bay, seat of honour HTGR demonstration project Huaneng Group, the whole world
Nuclear power plant reactor is one of 16 national science and technology key special subjects, is that First has the 4th generation of technology such as nuclear energy system safety in the world
The nuclear power generating sets of characteristic.This engineering will put into operation the end of the year 2012, plan in 2017 the end of the year power generation.Heat exchange unit is it
One important component part, interior cartridge module is the key components and parts of heat exchange unit, its essential shape a size of external diameterRoughness Ra≤3.2, length 8815mm, interior cartridge module is made up of material 6625, and this material belongs to nickel-base high-temperature
Alloy, has that Hard Inclusion is many, the feature of heat conductivity extreme difference, the feature that cutting force is big, cutting temperature is high, processing hardening tendency is big,
In turning process, vibration is big, belongs to typical difficult-to-machine material, it is very difficult to carry out turnery processing, and this assembly be again one thin
Long large-scale workpiece, must be aided with centre frame at present, and the deviation from circular from of workpiece raw material cylindrical is very big when carrying out size,
Not on a circle, when three support claws of centre frame are in direct contact with on its cylindrical, at all cannot turning of work piece,
Making cutwork cannot be carried out, secondly material 6625 can be deformed under three direct spinning of support claw of centre frame, causes
Whole workpiece bows.
Utility model content
For disadvantages mentioned above present in prior art, the purpose of this utility model is to provide in a kind of HTGR and changes
The turning adjusting sleeve of cartridge module on hot cell, it is possible to make the outer round surface formation one treating turner be available for centre frame and prop up
The circular surface of support, it is ensured that the carrying out of turnery processing rotary motion.
For achieving the above object, this utility model adopts the following technical scheme that
In a kind of HTGR, the turning adjusting sleeve of interior cartridge module on heat exchange unit, is located at the support claw of centre frame
In, including adjusting sleeve body, adjusting bolt and contact sleeve, adjusting sleeve body includes an interior annulus and is respectively connected to interior annulus two
The outer toroid of end, two outer toroid the most radially offers several screwed hole, is fed through an adjustment in each screwed hole
Bolt, each adjustment bolt is connected with a contact sleeve on the one end in the outer toroid center of circle.
The diameter of said two outer toroid is consistent, and more than the diameter of interior annulus so that the entirety of adjusting sleeve body is two
End projection, the shape under middle concave.
On described adjusting sleeve body, all of acute angle is chamfering or fillet.
The hardness of described contact sleeve is less than the hardness of interior cartridge module.
The surface of described interior annulus is provided with Quenching Treatment layer.
This utility model also has some beneficial effect following:
1. this utility model is located in outer toroid adjustment bolt and contact sleeve make workpiece fix more in adjusting sleeve
Firmly；
2. this utility model makes surface of the work no longer directly contact and relative motion occurs with the support claw of centre frame, no
Workpiece can be caused by rotary pressure deformation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram of utility model works state.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings with embodiment.
In conjunction with shown in Fig. 1 to Fig. 2, in a kind of HTGR provided by the utility model on heat exchange unit in cartridge module
Turning adjusting sleeve, be located in the support claw of centre frame 1, including adjusting sleeve body 7, adjust bolt 2 and contact sleeve 3, adjust
Set body 7 includes an interior annulus 4 and is respectively connected to the outer toroid 5 at interior annulus 4 two ends, and two outer toroid 5 are the most radially opened
Being provided with several screwed hole, be fed through one and adjust bolt 2 in each screwed hole, each adjustment bolt 2 is in outer toroid 5 center of circle
One end on be all connected with a contact sleeve 3.
During work, adjusting sleeve body 7 is sleeved on the cylindrical of workpiece 6, by adjusting the adjustment at adjusting sleeve body 7 two ends
Bolt 2, is fixed on the correct position of adjusting sleeve by workpiece 6, when this position, and interior annulus 4 surface of adjusting sleeve body 7 and car
The centre of gyration of bed 7 is consistent, and workpiece 6 rotates in this position, and adjustable workpiece 6 surface surplus is to suitable position, it is ensured that work
After part 6 surface surplus machines away, the excircle dimension of whole workpiece 6 and surface roughness reach the requirement of design.
It is also preferred that the left the diameter of said two outer toroid 5 is consistent, and more than the diameter of interior annulus 4 so that adjusting sleeve body 7
Entirety be that two ends are protruding, the shape under middle concave, interior annulus 4 thus can be clamped in three support claws of centre frame 1
Center so that whole workpiece 6 just can be at the central rotation of centre frame 1, it is thus achieved that one rotates support, can resist in processing each
The deformation that the power of kind produces.
It is also preferred that the left all of acute angle is chamfering or fillet on described adjusting sleeve body 7, it is possible to ensure adjusting sleeve body 7
It is sleeved on workpiece 6 cylindrical enterprising luggage when unloading, workpiece will not be abraded.
It is also preferred that the left the hardness of described contact sleeve 3 is less than the hardness of interior cartridge module, so enables to contact sleeve 3 and be clamped in
Time on manufactured workpiece 6 surface, will not disfiguring workpiece 6 surface, also workpiece 6 will not be caused big crimp.
It is also preferred that the left the surface of described interior annulus 4 is provided with Quenching Treatment layer, it can be ensured that the support claw of centre frame 1 supports
When the surface long term of interior annulus 4 works, it is possible to the shape that in keeping, annulus 4 is correct.
Those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to illustrate that this practicality is new
Type, and it is not used as to restriction of the present utility model, as long as in spirit of the present utility model, to the above
The change of embodiment, modification all will fall in Claims scope of the present utility model.
