The specific embodiment;

See Fig. 1,2,6,7, the utility model structure mainly is made up of a cnc boring and milling machine and index table and special fixture.Wherein, cnc boring and milling machine is provided with column 5, is assembled with main spindle box 6, main motion gearbox 22, main servo motor 23, feeding reduction box 24, feed servo motor 10, slide 8 and the lathe bed 9 of main shaft group 7 by existing structure; Index table adopts existing structure, is provided with turntable 2, turntable slide 1, and frock clamp 3 is fixed on the index table.The improved technical scheme of the utility model is: the casing 20 of main spindle box 6 is the L type, is Open architecture; See Fig. 3,4,5, steel guideway 13 is set on lathe bed 9, two plastic-sticking guiding rail faces 11 are set on slide 8.Be to improve the positioning accuracy that column 1 moves, alleviate the wearing and tearing of the guide pass that the friction of lathe slide 8 and lathe bed steel guideway 13 causes, three hydraulic pressure relief arrangements 12 are set on every plastic-sticking guiding rail face 11.The hydraulic pressure relief arrangement is provided with 12 oil cylinders 17, connects anti-drop rod 18-1 on the oil cylinder piston 18, and the carriage 14 of band roller 15 is set on steel guideway 13, and affixed concave spherical surface pad 16 on carriage 14 cooperates the protruding ball ring 19 of assembling on concave spherical surface pad 16; On protruding ball ring 19 and the concave spherical surface pad 16 the anticreep centre bore is set, anti-drop rod 18-1 inserts in the anticreep centre bore that the free gap is arranged on protruding ball ring 19 and the concave spherical surface pad 16.Between the horizontal plane of the open casing 20 of main spindle box 6 and main shaft group 7, horizontal linear guide rail 21-2 is set, vertical line guide rail 21-1 is set between the vertical plane of open casing 20 and main shaft group 7.

Operation principle: be pressure oil by hydraulic power unit enter oil cylinder 17 act on piston 18 above, produce a downward thrust, this thrust acts on the steel guideway 13 of lathe bed 9 by the roller 15 of protruding ball ring 19, concave spherical surface pad 16 and carriage 14.Thereby produce a thrust that makes progress, with a form off-load part such as the weight of 50 tons of slide 8, column 5 and main spindle boxes 6 etc. through rolling friction, thus the frictional force when reducing 8 pairs of bed ways of slide and moving.Slide 8 slide plastic-sticking guiding rail face 11 when bed ways move contacts all the time with the bed ways face, forms the composite guide rails form of a sliding friction and rolling friction.The pressure size of the hydraulic oil of relief arrangement 12 is determined through actual detected.Because adopt convex-concave ball ring structure, the cylindrical side bus that can adjust roller under the pressure of piston automatically contacts with lathe bed steel guideway face in moving process all the time equably.Avoid causing the damage of bed ways face.Have the main spindle box 6 column guide rails of milling spindle and boring axle to move up and down in the main shaft group and be Y-axis, main shaft group 7 moves forward and backward to Z axle on main shaft casing 20.Aesthetic in appearance for the cleaning and the main spindle box 6 that keep main shaft group 7, can the shield plate (not shown) be installed in main spindle box 6 outsides.

Concrete processing mode is as follows, the wheel hub 4 of a datum level processing is installed on the index table special jig 3, and a clamping just can machine three of wind-driven generators all working positions, i.e. faying face on the blade faying face is installed, seam, combined hole etc.

At first process wheel hub B face (in fact, the processing request of the B face of wheel hub, C face, E face is consistent, earlier which face of processing can), the seam that utilizes Digit Control Machine Tool to have on circular interpolation function milling B face and the B face reaches the drawing requirement, and the processing seam can process E face navel face and corresponding hole again simultaneously.Utilize Digit Control Machine Tool to have the arbitrary indexing function then, all through holes and thread Pilot hole on B face and the E face are processed.Whole process, milling flat, the processing seam, calibration boring is all finished on a coordinate system, is easy to guarantee the specification requirement of drawing, and institute's process component consistent size.The B face machines 120 ° of back index table rotations, carries out the processing of C face behind the chucking.Carry out calibration reprocessing D face after the C face completion of processing again, after three faying faces all process, unload parts, the next processing component of preparing of clamping.Because the hub size of the wind-driven generator of different size model is in different size, so three coordinate shift motions of the dedicated numerical control milling-boring machine that manufactures and designs enough satisfy different wheel hub processing requests.
