Using the method for the HTGR heat exchange unit interior cartridge module outer circle finish turning of the present invention, have steps of：
S1. first the unit interior cartridge module 6 that need to be processed is hung in lathe body 1 using floating suspender 7；
S2. by adjusting apparatus 3 be set in unit interior cartridge module 6 it is cylindrical on, then unit interior cartridge module 6 is erected at auxiliary
Above support meanss 4, then adjusting apparatus 3 unit interior cartridge module 6 it is cylindrical on fix；
S3. the position of rough turn lathe tool 2 is installed, starts lathe body 1, feed carries out turnery processing unit interior cartridge module 6
Excircle dimension；
S4. in Tutrning Process, then realized using on-line measurement device 5 and detected in real time in the case of without parking
The excircle dimension of unit interior cartridge module 6, untill the excircle dimension for being directly processed to requirement.
Also include S5, before on-line measurement device 5, standard length bar is first used between its side wheel 503 and measurement head 507
Calibrated, then stir driving lever 506, make the lower end of driving lever 506 to 501 outer side oscillation of support, and drive measurement head 507 and dial gauge
508 retract, in working preparation state, during measurement, by measurer be placed on unit interior cartridge module 6 it is cylindrical on, make the upper rolling on measurer
Wheel 502 and side wheel 503 and unit interior cartridge module 6 are cylindrical tangent, then stir driving lever 506, make the lower end of driving lever 506 to support 501
Interior side oscillation, so as to drive measurement head 507 and dial gauge 508 to advance, make measurement head 507 cylindrical tangent with unit interior cartridge module 6,
Just can on dial gauge 508 the cylindrical size of read assembly.
Incorporated by reference to shown in Fig. 7, the operation principle of on-line measurement device of the invention, δ is allowance in figure, when δ is not deposited
When the present invention and three contact points of measured workpiece be A, B, C, this 3 points on the correct profile of workpiece.
In the presence of δ, the present invention and three contact points of measured workpiece are A ', B ', C ', this 3 points not in workpiece just
On true profile, but have in workpiece on the profile of surplus, BC length is the actual diameter of workpiece.B ' C ' long are not the reality of workpiece
Diameter D, but the diameter measured by the not parking measurer of the present invention is used in workpiece process, i.e. length D ' between B ' C '.D
It is systematic error of the present utility model with the difference between D ', an analysis is done to this error below, from geometry
So that allowance δ takes 0.25mm as an example, then δ=0.25, D=280, then
When δ is much smaller than D/2,It is intended to 0.I.e. in the case of allowance, interior cartridge module its
Essential shape sizeIn the case of this required precision, it is believed that D=D '.
Preferably, the anterior angle of the cutter head 202 of the rough turn lathe tool 2 is 22.5 °, the relief angle of cutter head 202 is 7.3 °, cutter head
202 two front clearances are all 10.5 °, and the cutting edge inclination of cutter head 202 is 0 °, major cutting edge protection rib band 204 and point of a knife protection rib band
205 width is 0.2mm, and the roughness on the surface of chip curling groove 203 is≤Ra0.8.
Above-mentioned institute is angled, ensure that caloric value is reduced in turning process, the increase of the intensity of cutter head 202, improves car
The durability of knife.The major cutting edge that width is 0.2mm protects rib band 204 to protect rib band 205 with point of a knife, protects blade and point of a knife,
The durability of lathe tool is improved, because the cutter material of rapidoprint 6625 is more special, also lacks corresponding forming machine folder at present
Blade, cutter mainly still rely on hand grinding, are often ground as the protection rib at point of a knife is sharpened into arc-shaped, arc radius
It is excessive and the anterior angle angle at point of a knife is changed, cause cutting force to increase, be unfavorable for ensureing the durability of cutter head, sword on the contrary
The wide rib bands of 0.2mm are worn into, beneficial to hand grinding, and are more or less the same in terms of durability with sharpening into arc-shaped.
In addition, the topical oil stone of chip curling groove 203 is polished, roughness is not more than Ra0.8, reduce caloric value, improve
The durability of lathe tool.
Preferably, the middle part bearing block 402 of the auxiliary support apparatus 4 is less than two branch relative to the height of bottom plate 401
Height of the bracer slide 404 for bottom plate 401 so that two support blocks 406 can contact, and can thus be used in
The less unit interior cartridge module 6 of outside diameter.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
