Abstract
Solid cage elliptical pocket hole forming method of the present invention is related to field of machining, and in particular to solid cage elliptical pocket hole forming method, comprises the following steps：First the retainer ring billet for being drilled with halving hole in advance is clipped on bore hole mould, then with milling cutter with boring and Milling Process ellipse straight wall hole, the feed rate when parameter that lathe gives is Z coordinate and X-coordinate cutting is 25mm/min, and the speed of mainshaft is 1080 r/min；Milling cutter walks two circular hole positions of the Z coordinate down on straight two axis of boring, instruction is given again when cutter is in 2 axle position bottom dead centre to change and walk X-coordinate, a milling is to lifting after the first axle position from after the second axis, since the excess metal between two cylindrical holes is few, therefore a milling can milling into oval straight wall hole；The present invention is easy to operate, and Product Precision is high, and production efficiency is high, reduces production cost, increases economic benefit.
Description
Technical field
The present invention relates to field of machining, and in particular to solid cage elliptical pocket hole forming method.
Background technology
Due to the property requirement of aircraft bearing, the pocket hole of its retainer is designed to ellipsoidal surface shape, this shape
There is larger difficulty in manufacturing process.Generally try two kinds of processing methods：One kind is imitated with hard alloy form cutter
Type milling processes at one time, and is for second using oval slotting tool into oval straight wall hole, Ran Houyong by the circular hole slotting of preboring
Hard alloy arc forming knife milling ellipsoidal surface shape part again.The dimensional accuracy of both processing methods is unstable, especially
Be pocket hole sphere surface roughness it is poor.
The hard alloy form cutter that the first processing method uses is difficult manufacture, although the appearance and size of knife can use shaping
Grinding obtains, but the primary clearance of approximate helical formula cutter tooth can only be ground with manual operations, and at this moment the precision of milling edge is just difficult to protect
Card, in addition, cutter, with after blunt reconditioning, imitative type device is needed to change and debugged again.These factors cause the pocket hole ruler finally milled out
Very little precision is unstable, and surface roughness is poor.As for second of processing method, its manufacturing process is slightly improved, the possibility of realization
Property is larger.Know through engineer testing, the oval straight wall bore portion effect in slotting pocket hole is pretty good, but oval slotting tool manufacture difficulty is big, closes
The manufacture of the spheric carbide-tipped milling cutter of key is still problem, and milling effect is poor.And the vertical wall section and sphere in a pocket hole
Part will the positioning processing twice on hydraulic pressure slotting machine and milling machine respectively, it is misaligned to produce the two-part axis in pocket hole, its
Positional precision is undesirable.
The content of the invention
To solve the above-mentioned problems, the present invention provides a kind of easy to operate, and Product Precision is high, and production efficiency is high, reduces life
Cost is produced, increases the solid cage elliptical pocket hole forming method of economic benefit.
Solid cage elliptical pocket hole forming method of the present invention, comprises the following steps：
The first step, first clips the retainer ring billet for being drilled with halving hole in advance on bore hole mould, then with milling cutter with boring
With Milling Process ellipse straight wall hole, the feed rate when parameter that lathe gives is Z coordinate and X-coordinate cutting is 25mm/min, main
Rotating speed is 1 080 r/min；
Second step, milling cutter are walked two circular hole positions of the Z coordinate down on straight two axis of boring, are given again when cutter is in 2 axle position bottom dead centre
Fixed instruction, which changes, walks X-coordinate, and a milling is to lifting after the first axle position from after the second axis, due to the excess metal between two cylindrical holes not
It is more, thus a milling can milling into oval straight wall hole；
3rd step, lathe change sphere combination milling cutter, with boring at a slow speed and milling spheric pocket hole, the Z coordinate that lathe gives into
Feed rate with X-coordinate is still 25 mm/min, but the rotating speed of main shaft is reduced to 79 r/min, and cutter is first from elliptical aperture during processing
Center axle position is walked, coordinate down boring, and after control sphere paper centering scale cun is reached, cutter switchs to walk X-coordinate milling immediately, to the
One axis axle position returns again to horizontal milling to the second axis axle position, and the center axle position finally returned to elliptical aperture lifts cutter, complete to this
Ellipsoidal surface shape pocket hole with regard to completion of processing；
4th step, with manual switch decile, completes to process to hole one by one in order.
Preferably, used equipment is MOOG points position digital-control boring-milling machine.
Preferably, the cylinder blade of the cutter allows maximum inverted cone degree to be 0.005mm.
The present invention is easy to operate, and Product Precision is high, and production efficiency is high, reduces production cost, increases economic benefit.
