Abstract
The processing method of the oblique oil-way of a kind of internal ring, belongs to machining technique field.Step is as follows: 1) selecting diameter D 2 3mms more smaller than the sphere diameter of workpiece of metal saw, the cutting edge of metal saw is identical with the shape of oil groove；(2) metal saw is arranged in CNC milling machine；(3) universal dividing head is manually tilted, fixing after gyroaxis being tilted by oil-way angle α；(4) at the manual scroll chuck of the index dial colonel a diameter of 250mm of positive clamping；(5) after clamping workpiece, starting nc program, CNC milling machine main shaft quickly moves on x, y, z three direction of principal axis, until the center of metal saw overlaps with the workpiece to be processed centre of sphere；(6) metal saw enters inner hole of workpiece, mills out an oil-way；(7) adjust index dial, by index dial fixed angle mouth circular index, then clamp workpiece, repeat step (5) (7), until all oil-way completion of processing.Present invention achieves the digital control processing of a plurality of discontinuous oblique oil groove, efficiency is high, low cost.Shortage special processing equipment or Single unit job lot production there is the best economic benefit.
Description
Technical field
The processing method that the present invention relates to the oblique oil-way of a kind of internal ring, belongs to machining technique field.
Background technology
General linear oil groove is adding man-hour, only need to be directly installed on knife rest by hook groove cutter on lathe, pass through middle carriage
The regulation degree of depth, then drags saddle back and forth with hands.So, linear oil groove just machines.However as machine-building
Development and the rigors of part time job environment, the axle sleeve of some engineering machinery, for improving lubricant effect, designs oil groove
Become tilt to be interrupted oil groove groove or the crossed oil grooves of X font crossed oil grooves replacement 8-shaped shape.
Shown in internal ring (such as Fig. 1), it is that aircraft actively falls the lower intersection point of frame, packs up at main landing gear, when putting down, as
Main support point, internal ring makees angular movement at a slow speed in race ring, it is ensured that main landing gear completes folding and unfolding.Part surfaces externally and internally is except having
Article two, outside annular oil groove, being also dispersed with three discrete oblique oil grooves on endoporus, this kind is designed to axle is effectively ensured in hole
Interior sufficient lubrication, but this structure is compared with the crossed oil grooves of common 8-shaped shape, it is impossible to process on lathe, to part
Manufacture brings great difficulty.
Summary of the invention
In order to solve the processing problems of above-mentioned existence, the present invention provides the processing method of the oblique oil-way of a kind of internal ring.
It is an object of the invention to be achieved through the following technical solutions: the processing method of the oblique oil-way of a kind of internal ring, its
It is characterised by:
(1) the diameter D 2-3mm more smaller than the sphere diameter of workpiece of metal saw, the cutting edge of metal saw and oil groove are selected
Shape is identical；
(2) metal saw is arranged in CNC milling machine；
(3) universal dividing head is manually tilted, fixing after gyroaxis being tilted by oil-way angle α；
(4) at the manual scroll chuck of the index dial colonel a diameter of 250mm of positive clamping；
(5) after clamping workpiece, starting nc program, CNC milling machine main shaft quickly moves on x, y, z three direction of principal axis
It is dynamic, until the center of metal saw overlaps with the workpiece to be processed centre of sphere；
(6) metal saw enters inner hole of workpiece, mills out an oil-way；
(7) adjust index dial, by index dial fixed angle mouth circular index, then clamp workpiece, repeat step (5)-(7),
Until all oil-way completion of processing.
Beneficial effects of the present invention: the present invention uses said method to process, is processing side oil groove, after upset part,
After height gauge centering oil groove, then being processed groove at next, 3 oil grooves are uniformly distributed relative to 120 °, position.Make a plurality of non-company
Continuous oblique oil groove is also applied for digital control processing, and efficiency is high, low cost.Shortage special processing equipment or Single unit job lot production are had
The best economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the processing workpiece internal ring that the present invention relates to.
Fig. 2 is clamping view in the course of processing.
Detailed description of the invention
Oil-way is the space oil groove on interior annular distance face, becomes a fixed angle with inner ring axis, and the centre of sphere leans at workpiece
Nearly workpiece end face, and the radius of oil groove is the least, the degree of depth is the most shallow, if workpiece can be pressed oil groove fixed angle, makes oil groove be in
Horizontal level, uses formed cutter milling processing cutting force not too large.Therefore the diameter D ball than workpiece of metal saw is selected
The smaller 2-3mm in footpath, the cutting edge of metal saw is identical with the shape of oil groove.Concrete processing method is as in figure 2 it is shown, by omnipotent indexing
1 manually tilts, fixing after being tilted by gyroaxis (the i.e. the 4th axle) by oil-way angle α, for ease of quick-clamping workpiece,
The manual scroll chuck of a diameter of 250mm of the positive clamping of index dial colonel 2.After clamping workpiece 3, start nc program, numerical control
Milling machine spindle is rotated by the rotating speed set, and the center that x, y, z three axle quickly moves to metal saw just overlaps with the workpiece centre of sphere,
Now, metal saw enters inner hole of workpiece, but will not touch inner hole of workpiece surface, because the diameter D of metal saw compares workpiece
The smaller 2-3mm of sphere diameter.Add man-hour, mill out an oil-way, after then index dial presses fixed angle mouth circular index again
Clamping workpiece, continues next oil-way of milling, and go round and begin again circulation, until all oil-way machines.
