Abstract
The invention relates to the field of machining, in particular to a machining method for a solid-retainer elliptical-spherical pocket. The machining method includes the following steps that a retainer ring blank in which an equal division hole with the diameter of 22 mm is pre-drilled is firmly clamped on a hole boring mold, and then an elliptical straight-wall hole is bored and milled with an finish milling cutter, wherein given parameters of a machine tool are the feeding rate during z coordinate cutting and x coordinate cutting of 25 mm/min and the rotating speed of a main shaft of 1,080 r/min; the finish milling cutter moves downwards along the z coordinate to directly bore two circle hole positions on two shafts; when located in the axial-position bottom dead center, the cutter is given an instruction and moves along the x coordinate, and the cutter is lifted after carrying out milling to the original shaft position from another shaft position; as the amount of excess metal between the two cylindrical holes is small, the elliptical straight-wall hole can be milled through once milling; the spherical combination finish milling cutter of the machine tool can be automatically switched to bore and mill the spherical pocket. The machining method is easy to operate, the machining quality of a workpiece can be guaranteed, the production efficiency can be improved, and the production cost can be reduced.
Description
Technical field
The present invention relates to field of machining is and in particular to the processing method in solid cage ellipsoidal surface shape pocket hole.
Background technology
Property due to aircraft bearing requires, and the pocket hole of its retainer is designed to ellipsoidal surface shape, this shape
Larger difficulty is had on manufacturing process.Typically try two kinds of processing methods: one kind is to be imitated with hard alloy form cutter
Type milling processes at one time, and second is, using oval slotting tool, the circular hole slotting of preboring is become oval straight wall hole, Ran Houyong
Hard alloy arc forming knife milling ellipsoidal surface shape part again.The dimensional accuracy of both processing methods is all unstable, especially
Be pocket hole sphere surface roughness poor.Cutter to above two processing method and frock is analyzed it is believed that the first
The hard alloy form cutter that processing method uses is difficult to manufacture although the overall dimensions of knife can be obtained with plunge grinding, but closely
Primary clearance like spiral cutter tooth can only be ground with manual operations, and at this moment the precision of milling edge is just difficult to ensure that, additionally, cutter is used
After blunt reconditioning, imitative type device need to be changed and again debug.These factors lead to the pocket hole dimensional accuracy finally milling out unstable, table
Surface roughness is poor.As for second processing method, its manufacturing process is slightly improved, the probability of realization is larger.Through technique examination
Test and know, the oval straight wall bore portion effect in slotting pocket hole is pretty good, but oval slotting tool manufacture difficulty is big, crucial spheric hard closes
The manufacture of golden milling cutter is still a difficult problem, and milling effect is poor.And the vertical wall section in a pocket hole and land portions will be respectively in hydraulic pressure
On slotting machine and milling machine, positioning processing twice, will certainly produce that the two-part axis in pocket hole is misaligned, its positional precision is undesirable.
Content of the invention
In order to solve the above problems, the present invention provides one kind simple to operate, can guarantee that the crudy of workpiece, improves and produces
Efficiency, the processing method reducing the solid cage ellipsoidal surface shape pocket hole of production cost.
The processing method in solid cage ellipsoidal surface shape pocket hole of the present invention, comprises the following steps:
The first step, the first retainer ring billet being drilled with diameter 22mm halving hole in advance is contained on bore hole mould and clips, and then uses finish-milling
With boring and Milling Process ellipse straight wall hole, the parameter that lathe gives is that feed rate when z coordinate and x coordinate cutting is to knife
25mm/min, the speed of mainshaft is 1080r/min, and milling cutter walks two circular hole positions down on straight boring two axle for the z coordinate, when cutter exists
Give instruction during one axle position bottom dead centre again to change and walk x coordinate, lift after another axle position milling to primitive axis position, due between two cylindrical holes
Excess metal few, therefore a milling just millable becomes oval straight wall hole；
Second step, lathe just changes sphere combination milling cutter automatically into, and with boring at a slow speed and milling spheric pocket hole, lathe gives
The feed rate of z coordinate and x coordinate is still 25 mm/min, but the rotating speed of main shaft is reduced to 79r/min, and during processing, cutter is first from ellipse
The center processing in hole: coordinate down boring, control sphere paper centering scale cun when reaching, cutter switchs to walk z coordinate milling immediately, to upper
State an axle position in step and return again to horizontal milling to another axle position, the center finally returning elliptical aperture lifts cutter, complete to this
Ellipsoidal surface shape pocket hole with regard to completion of processing；
3rd step, with manual switch decile, completes to hole to process in order one by one.
The present invention is simple to operate, can guarantee that the crudy of workpiece, improve production efficiency, reduces production cost.
Specific embodiment
The processing method in solid cage ellipsoidal surface shape pocket hole of the present invention is it is characterised in that comprise the following steps:
The first step, the first retainer ring billet being drilled with diameter 22mm halving hole in advance is contained on bore hole mould and clips, and then uses finish-milling
With boring and Milling Process ellipse straight wall hole, the parameter that lathe gives is that feed rate when z coordinate and x coordinate cutting is to knife
25mm/min, the speed of mainshaft is 1080r/min, and milling cutter walks two circular hole positions down on straight boring two axle for the z coordinate, when cutter exists
Give instruction during one axle position bottom dead centre again to change and walk x coordinate, lift after another axle position milling to primitive axis position, due between two cylindrical holes
Excess metal few, therefore a milling just millable becomes oval straight wall hole；
Second step, lathe just changes sphere combination milling cutter automatically into, and with boring at a slow speed and milling spheric pocket hole, lathe gives
The feed rate of z coordinate and x coordinate is still 25 mm/min, but the rotating speed of main shaft is reduced to 79r/min, and during processing, cutter is first from ellipse
The center processing in hole: coordinate down boring, control sphere paper centering scale cun when reaching, cutter switchs to walk z coordinate milling immediately, to upper
State an axle position in step and return again to horizontal milling to another axle position, the center finally returning elliptical aperture lifts cutter, complete to this
Ellipsoidal surface shape pocket hole with regard to completion of processing；
3rd step, with manual switch decile, completes to hole to process in order one by one.
The present invention is simple to operate, can guarantee that the crudy of workpiece, improve production efficiency, reduces production cost.
