Embodiment
For make the present invention illustrate be more fully apparent from, the present invention is described in further details below in conjunction with the accompanying drawings.
Embodiment：
Referring to figs. 1 to Fig. 4, the present embodiment provides a kind of highly-efficient processing device of dish, including dish fixture 1, the and of cutter 2
Rolling center 3, dish fixture 1 include apotting spindle 11, back-up ring 12, locking nut 13 and installation pedestal 14, installation pedestal 14
One end be plane, the relative other end of installation pedestal 14 is clamped on lathe, and one end of apotting spindle 11 is perpendicularly fixed at peace
In the plane for filling pedestal 14, locking nut 13 is installed with apotting spindle 11, and on the apotting spindle 11 of the inner side of locking nut 13
Back-up ring 12 is additionally provided with, top locating slot 15, rolling center 3 and apotting spindle are offered at the center of the other end of apotting spindle 11
11 is coaxial, and rolling center 3 is held out against in the top locating slot 15 of the other end of apotting spindle 11, and the cutter 2 passes through machine
Bed knife rest is arranged at the side of dish fixture 1,
The handle of a knife of cutter 2 matches with lathe model ensures that point of a knife and machine tool chief axis pivot are contour, with enough intensity, just
Property, form do not do excessive requirement, and tool orthogonal rake α determines according to part material, in principle the bigger resistance to cutting of tool orthogonal rake
It is smaller, it is more favourable to processing, but consider that the intensity span of cutter should not be too big.Non-ferrous metal anterior angle easily causes bundle very much greatly
Knife phenomenon.Summoning recommends tool orthogonal rake α：3 °~6 °, non-ferrous metal, nonmetallic, tool orthogonal rake α：8 °~12 °, tool clearance
γ in principle tool clearance cut more greatly with finished surface rub it is smaller, to process it is more favourable, but consider cutter intensity and radiating
Condition span should not be too big, and particularly non-ferrous metal relief angle is too big easily causes knife phenomenon, recommends tool clearance γ γ：
3 °~5 °.Angle beta span should not be too small after cutter side, when particularly part outside dimension is larger, value too little Yi with to add
Work surface, which produces friction, makes cutting heat substantially increase, and recommends angle beta after cutter side：6 °~10 °, cutter working approach angle λ values too little Yi
Cutting heat is set substantially to increase with producing friction with finished surface, the value too too big influence of the big residual ridge height of finished surface cut
The surface quality of product, recommend cutter working approach angle λ：3 °~5 °, tool inclination angle ρ determines according to part material, to ensure cutter
Intensity is principle, and the smaller tool strength of value is better, and impulsive force is larger during interrupted cut or even can select negative value, recommends cutter
Cutting edge inclination ρ：1 °~3 °, blade widths are not more than 3.5 mm, and the too big resistance to cutting of blade widths size is big, has caused process system
Vibrations, therefore blade widths size is as far as possible small, but need to ensure to cut off blank at surplus minimum during processing, do not allow clout whole
Circle comes off, keep clout peel off when chip breaking into 4 pieces of corner materials, avoid forging a knife.Chip-breaker is not less than using groove width compared with sipes type, groove width
5mm, volume bits boss is as far as possible low, not higher than 2mm, uses such groove profile to be easy to chip-flowing with finished surface, avoids flowing to be added
Work surface wrap is to causing phenomenon of forging a knife on cutter.
Apotting spindle 11 is tightened uses alloy tool steel Cr12MoV in installation pedestal 14, the material of installation pedestal 14
Be ground after roughing after quenching+tempering it is cylindrical be made, hardness range HRC50~55 after quenching+tempering, there is provided enough is wear-resisting
Property and rigidity, to ensure repetitive positioning accuracy.Internal thread does not do excessive requirement and matched with the external screw thread of apotting spindle 11, positions
The material of mandrel 11 uses steel alloy 40Cr modulation treatments after roughing, after being assembled with installation pedestal 14, with installation pedestal 14 and
Be ground on the basis of top locating slot 15 it is cylindrical be made, hardness range HRC30~35 after modulation treatment, there is provided enough wearability,
Rigidity and rotating accuracy, to ensure repetitive positioning accuracy, apotting spindle 11 is easy to be applied to not with the split of installation pedestal 14 design
With the product of endoporus requirement, when endoporus requires different, different demands can be met by changing apotting spindle 11, improve versatility and
Interchangeability, the demand of different product being met on the premise of cost-effective, the material of back-up ring 12 uses carbon steel 20# steel, without
Heat treatment directly machining is made, and the softer materials behavior of use is in order that there is back-up ring certain plasticity to be easy to part
Step up, the material of locking nut 13 is made of the machined rear modulation treatment processing of steel alloy 40Cr, hardness after modulation treatment
Scope HRC38~45, there is provided enough wearability, rigidity.
The concrete technology method of dish highly-efficient processing is as follows：
First parts to be processed 5 is drilled, multiple parts 5 are sheathed on apotting spindle 11 successively after drilling, and by apotting spindle
11 are fixed in installation pedestal 14, screw locking nut 13 and part 5 is fixed between back-up ring 12 and installation pedestal 14；
Installation pedestal 14 is clamped on lathe, and held out against using rolling center 3 in the top locating slot of the end of apotting spindle 11
In 15；
Cutter 2 is installed on the knife rest of lathe, and cutter 2 is adjusted to the side trial-mix strength of dish fixture 1, it is complete to knife
Processing is completed into latter secondary turning.
