D. auxiliary mould is pulled down and is fixed on boring machine, carry out areole processing;
E. carry out six equation graduation line;
F. the auxiliary mould after line is pulled down and is again fixed on vertical lathe workstation, thin-wall ring part is cut from auxiliary mould, and the upper surface of the flat auxiliary mould of car, in order to using next time.
G. according to the bisector pulling, thin-wall annular part line is cut into six equal portions.
Preferably, in steps A, be welded on auxiliary mould disconnected thin-wall annular part
Preferably, in steps A, before welding, make thin-wall annular part center and auxiliary mould center superposition.
Preferably, in steps A, the height of thin-wall annular part is greater than designing requirement 15mm at the most.
Preferably, in step B, by pressing plate, bolt, auxiliary parallels, packing ring and nut, auxiliary mould is fixed on vertical lathe workstation, the thickness of auxiliary parallels is greater than the thickness of auxiliary mould.
The invention has the beneficial effects as follows:
(1) by being welded on auxiliary mould before thin-wall annular part processing, make thin-wall annular part and auxiliary mould form an entirety, add and only need man-hour auxiliary mould to be fixed, avoided fixture in existing technique directly fix the thin-wall annular part distortion of thin-wall annular part generation and process the problem that oscillation mark appears in rear thin-wall annular part.
(2) auxiliary mould is a steel annulus, simple in structure, with low cost, has enough rigidity and reusable.
(3) this frock has effectively reduced the circularity requirement of workpiece after turning processing, and the situation of the pore size distribution inequality causing because of workpiece deformation in the time of process side cinclides.
(4) this frock has effectively ensured that workpiece is divided into the halving precision after six parts.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the present invention will be further described.
Embodiment 1: a kind of auxiliary mould of thin-wall ring part processing, described auxiliary mould 2 is an annulus, and the internal diameter of described annulus is less than the internal diameter of thin-wall ring part 3, and the external diameter of described annulus is greater than the external diameter of thin-wall annular part 3; Described auxiliary mould 2 is steel, and annealed processing; The external diameter of described annulus is greater than the external diameter 60mm of thin-wall annular part 3.
The technique that adopts the processing thin-walled annular element of above-mentioned auxiliary mould, step is as follows
A. thin-wall annular part 3 is welded on auxiliary mould 2;
