Abstract
The processing method of thin-walled sphere with special shape involves in the field of machining and specifically relates to the processing method of thin-walled sphere with special shape, which includes the following steps: forging and cutting stock. The Inner and outer diameter of rough turning of common lathe are left the margin from 4mm to 5mm after annealing. One side of outer diameter and semi-finishing and internal spherical surface of finishing turning are clamped by the chuck of CNC, and the auxiliary clamping fixture is used to clamp the spherical surface of rough turning. The machining center uses rotation function of B-axle to process three 30o base levels and pores and one tolerance of hole. The bench worker finishes thickening parts of tolerance of hole and uses clamping fixture to knock on the inside to let the thickening parts of tolerance of hole concave to internal spherical surface. The auxiliary fixture and the spherical outer surface of CNC and finishing turning are used to meet requirement of the dimensional tolerance. The common lathe is clamped by the frock clamp. The frock clamp is used to process three external threads, the other threads are finished by using second-tap tapping. The bench worker sands outside surface and smooth the sharp edge and spray lacquer except each interface. The invention has advantages of being easy to operate, convenient to process, and easy to cut. What's more, the invention saves production cost and ensures working accuracy.
Description
Technical field
The present invention relates to field of machining is and in particular to thin-wall special-shaped the processing of sphere method.
Background technology
Thin-wall special-shaped spheroid product material is precipitation-hardening stainless steel, requires б >=1200mp, wall thickness is after heat treatment
20mm, surface roughness is 1.6 ц m.Form and position tolerance is 0.03mm ~ 0.08mm, protrusion angles interface requirement overall processing at three,
Do not allow to weld；Seam external screw thread is processed after requiring welding；For increasing intensity, the certain increasing of each seam outer ball surface design
Thick region, and require rounding off, this just significantly increases difficulty of processing.Traditional diamond-making technique should be by five-axis robot
Center is combined with numerically controlled lathe and is completed to process, but processing charges is higher.Determine using new combinational processing method through analysis and research,
Design assistant frock clamp, does datum level and hole by machining center, and remaining position is completed to process by other lathes.Decrease to many
The dependence of Shaft and NC Machining Test processing center machine tool, reduces processing charges.There is following difficult point in the processing of this workpiece: this workpiece material is
Precipitation-hardening stainless steel, difficulty of processing is big.Following several respects of concrete manifestation: 1. processing hardening is serious；2. cutting force is big；3. cut
Temperature is high；4. cutting is not easily broken, easily bonds；5. cutter is easy to wear.(2) thin-wall part, yielding.Same fashionable dress
Folder is difficult.
Content of the invention
In order to solve the above problems, the present invention provides a kind of simple to operate, easy to process, easily cutting, and can save life
Produce cost it is ensured that the thin-wall special-shaped the processing of sphere method of machining accuracy.
The present invention thin-wall special-shaped the processing of sphere method comprises the following steps:
The first step, forging blanking, the rough turn internal-and external diameter of engine lathe after annealing, made allowance 4mm ~ 5mm；
Second step, numerical control lathe chuck clamping one end external diameter half essence, smart car Internal Spherical Surface, recycle the auxiliary rough turn ectosphere of mold clamping
Face；
3rd step, machining center is using tolerance hole at 30 degree of datum levels at b Shaft angle degree function processing three and hole and；
4th step, pincers worker machines tolerance hole and thickens section, and inwardly being tapped using mold makes it concave towards Internal Spherical Surface；
5th step, using auxiliary clamp numerical control lathe smart car spherical outside surface, reaches size tolerance requirements；
6th step, using Internal hole positioning clamping, boss external diameter and thicken at section at engine lathe rough turn three, allowance 2mm ~ 3mm,
External diameter allowance 1mm at numerical control Vehicle Processing screw thread, end face stays 0.5mm, and remaining machines, and remaining area pincers worker is according to model refine
Complete；
7th step, boss external diameter clamping centering at three pressed by engine lathe, processes Nei Tai hole；
8th step, with upper hemisphere integral solder, remaining joint weld, with a cone tapping at remaining screw thread；
9th step, aging strengthening model hrc38-40；
Tenth step, using external screw thread at frock clamp clamping engine lathe processing three, is completed with plug tap tapping at remaining screw thread；
11st step, pincers worker sanding outer surface, sharp edge is blunt；
12nd step, in addition to each seam, remaining spray painting completes.
The present invention is simple to operate, easy to process, easily cuts, and can save production cost it is ensured that machining accuracy.
