step one, rough machining of thin-wall parts:
mounting the thin-wall part on a first support base connected with a machine tool and sleeving the thin-wall part on the expandable part; the driving part simultaneously drives the upper conical block and the lower conical block to simultaneously extrude the plurality of blocks of the expandable part so as to control the plurality of blocks to simultaneously open by a first set angle, under the first set angle, the first plurality of blocks are attached to the inner wall of the thin-wall part, and the blocks are fixed on the supporting base through a plurality of connecting pieces so as to carry out rough machining on the thin-wall part;
step two, after rough machining is finished, removing the connecting pieces, and then controlling the blocks to be restored to the initial state by the driving part;
step three, fine machining of the thin-wall part:
mounting the roughly machined thin-wall part on a second support base connected with the machine tool and sleeving the thin-wall part on the expandable part; the driving part simultaneously drives the upper conical block and the lower conical block to simultaneously extrude the plurality of blocks of the expandable part so as to control the plurality of blocks to simultaneously open at a second set angle, under the second set angle, the first plurality of blocks are attached to the inner wall of the thin-wall part subjected to rough machining, and the blocks are fixed on the supporting base through a plurality of connecting pieces so as to carry out fine machining on the thin-wall part;
step three, after finishing, removing the connecting pieces, and then controlling the blocks to be restored to the initial state by the driving part;
step four, processing the upper surface and the lower surface of the thin-wall part:
before the processing of upper and lower face, carry out the regulation of a plurality of blocks opening range again after the adjustment inside lining device direction, the drive division is installed in last toper piece, the block is with in the centre bore that toper piece formed down, a plurality of block upper portions of toper piece top surface control are opened in the extrusion of drive division, and simultaneously, drive division and toper piece threaded connection down, the toper piece screw hole in-process under the drive division screw in, toper piece shifts up extrusion block lower part conical surface down, thereby control a plurality of block lower parts and open, a plurality of blocks open the back simultaneously and closely laminate with thin wall part, the drive division is unscrewed to the processing completion, a plurality of blocks of drive division control resume to initial condition.
