Abstract
The invention discloses a processing technology for thin annular parts. The problems that the out-of-tolerance of size and geometric tolerance of the thin annular parts is easily caused in the traditional processing technology are solved. The processing technology for thin annular parts comprises the following steps of: installing a core shaft, and turning an outer circle; sleeving the outer circle and turning an inner circle; carrying out aging treatment. The processing technology for the thin annular parts is reasonable, and the finishing quality of the thin annular parts is improved.
Description
Technical field
The present invention relates to processing technology field, particularly thin ring-shaped work pieces processing technology.
Background technology
Current, the volume of engineering goods is tending towards miniaturization, part is also corresponding to " little ", " thin ", " gently " future development. therefore, the thin ring-shaped work pieces that run in process etc. are more and more. because this class part self rigidity is not enough, flexibility is had a surplus, adopt conventional clamping not only cannot meet machining accuracy, and produce form error because clamping force causes part elastic deformation, become one of difficult point in processing.
What in processing, thin ring-shaped work pieces the most easily occurred is size distortion and the excessive temperature distortion causing of the depth of cut causing because of chuck location.In view of the situation, in design, avoid during frock directly workpiece location itself, and by adopt auxiliary mould internally, external diameter locates and processes, because workpiece is subject to the workpiece radial dimension that claw clamping force produces, be out of shape effectively avoiding.
Summary of the invention
Technical problem to be solved by this invention can realize by following processing step: upper mandrel car external diameter, cover cylindrical car internal diameter, timeliness.
Step 1: upper mandrel turning
(1) after the blank exocuticle of car coring axle, go up again soft three-jaw clamping and positioning, according to the internal diameter size of workpiece and tolerance, the outside dimension of mandrel is dwindled to 0.01mm～0.015mm, allow workpiece on mandrel, have a basic centralized positioning.
(2) at the dark 2mm of outer cover plate one end car, on circumference, stay 1 width and the suitable annulus of thin ring-shaped work pieces wall thickness, and make a call to a through hole in outer cover plate center, pore size can pass through lock-screw naturally.
(3) with the outer end circle of annulus part " withstanding " workpiece on outer cover plate, and by screw lock, make workpiece in process in center, to guarantee the axiality of workpiece.
(4) cylindrical of outer cover plate and mandrel should be more lower slightly than the cylindrical of workpiece, is less than workpiece outside dimension 0.80～1.0mm;
Step 2: cover cylindrical boring
(5) thin ring-shaped work pieces is loaded in core sleeve, screws the inner diameter wall that workpiece is close to mandrel locate processing with locking cover plate by screw thread.Its internal diameter is less than core sleeve and the internal diameter size 0.80～1.0mm that locks cover plate.Cutter is at processing abundant turning surface during finish turning, and the frock of can " not swiping " is again surperficial;
Step 3: timeliness
(6) should between finishing step, arrange Ageing Treatment, take 2～3d as 1 timeliness cycle.Like this, both can make the metallographic structure of material tend to balance stable, can eliminate the internal stress that preceding working procedure left behind again, guarantee dimensional tolerance and required precision;

The specific embodiment
(1) while locking with soket head cap screw, do not exert oneself, only need be wrenched slightly, because workpiece compressive deformation can make the radial dimension after processing less than normal;
(2) locking cover plate overwinds in order to avoid workpiece stress deformation;
(3) depth of cut is controlled at 0.03～0.08mm according to workpiece material difference;
(4) rotating speed is controlled at 400～1200r/min according to workpiece material difference.
Claims (1)
