Step 2：Roughing：Endoporus circumference, excircle and former and later two ends of lathe roughing steel tube blank are used first
Face provides processing positioning for following process process, and finishing is stayed in endoporus circumference, excircle and former and later two end faces of steel tube blank
Spare time measures；
Step 3：Finishing：With lathe finishing endoporus circumference and former and later two end faces, the endoporus circumference of steel pipe is made to reach
The inner arc surface size of eccentric arc panel, the length of steel pipe reach the length of eccentric arc panel；
Step 4：Bore hole：Four busbares are uniformly drawn in the external peripheral surface of steel pipe, every busbar is along the axial direction side of steel pipe
The first hole, two the second holes and the two third holes on eccentric arc panel are completed to setting with boring machine in the position bore hole of busbar
Processing；
Step 5：Cut-out：Disconnected in the centre position milling of two neighboring eccentric arc panel with milling machine, the rear and front end of steel pipe is equal
Break surplus there are milling, have no progeny in whole millings, then is with handsaw that the milling of the rear and front end of steel pipe surplus of breaking is sawed-off successively；
Step 6：Width is processed：It is two of Milling Machining bias arc panel long on milling machine using busbar as symmetrical center line
The width processing of eccentric arc panel is completed on side；
Step 7：Exterior arc surface and both ends cone face process：A pair of eccentric arc panel is symmetricly set on the upper of special fixture
Lower both ends, special fixture include two clamp bodies, front clamp, rear acrosome and eccentric top plate, and front clamp and rear acrosome are along level side
To coaxial arrangement, the upper and lower ends of front clamp and rear acrosome outer wall are respectively fixedly mounted with that there are one clamp bodies, and two clamp bodies are relative to preceding
The central axis of clamp and rear acrosome is symmetrical arranged, and cavity is equipped between front clamp and rear acrosome, and eccentric top plate pushes up after being packed in
On the outer end face of body, with processing at cavity opposite position there are two connecting hole on each clamp body,
Using two the second holes of eccentric arc panel as the Set and Positioning hole when exterior arc surface of the eccentric arc panel of processing, use
Locking stud is inserted into successively on the second hole of eccentric arc panel and the connecting hole of special fixture, and the inside of clamp body is equipped with spiral shell
Mother, nut spinning is in the end of locking stud, after completing clamping, with the exterior arc surface and two end cones of lathe turning bias arc panel
Face.
The beneficial effects of the invention are as follows：The present invention can be realized to the turnery processing of eccentric arc panel, only pass through common in-vehicle
Process can be completed in bed, and production efficiency is high, and deflection is small, ensure that the required precision of product, can be used for producing in batches.Together
When the present invention clamping tool it is simple, work efficiency is high, and the process-cycle is short, and dedicated numerical control machining center equipment need to be used by overcoming
Technical barrier reduces production cost, and the technology that can be generalized to eccentric arc class part in field of machining is worked as
In.
