Description

The special-purpose thin-walled machining mould of piston of automobile cylinder barrel
Technical field
The utility model relates to a kind of machining mould, relates in particular to a kind of machining mould that is suitable for turning thin-wall cylinder.
Background technology
The barrel of piston of automobile cylinder barrel is very thin, and about 2-4 millimeter, when carrying out turning processing inner surface and outer surface, easily produces distortion, affects product quality, and we always can not meet client's demand in process, are finding suitable machining mould always.
Utility model content
For adapting to the processing of piston of automobile cylinder barrel thin-walled, improve machining accuracy and quality, the utility model has designed the special-purpose thin-walled machining mould of a kind of piston of automobile cylinder barrel.Be divided into inner and outer wall processing two parts, i.e. inner surface machining mould, outer surface machining mould.
The technical solution of the utility model is:
The first car inner surface of this workpiece, first selects inner surface machining mould; Comprise two parts: base chuck, gland, in the middle of base chuck, there is circular port, the circular orientation seam groove that circular port arranged outside is corresponding with workpiece lower surface diameter of axle size, at three bolts hole of positioning spigot groove arranged outside;
Gland comprises sleeve, presses mouth, support bar, the internal diameter of sleeve and height are corresponding with workpiece, press lid in workpiece top annular upper surface, support bar end arranges the bolt corresponding with three bolts hole of base chuck tight, make fixedly clamping of workpieces of gland, then integral installation is processed on lathe spindle.
The first car outer surface of this workpiece, selects outer surface machining mould; Comprise the core that rises, the piece that rises, the piece cylinder that rises, connecting axle, bracket cup hole, double-screw bolt, nut, connecting axle, the piece cylinder that rises, the piece that rises are structure as a whole, connecting axle connects lathe chuck, by end to root chap gradually, to form interference fit with lathe spindle, axle center, connecting axle end arranges bracket cup hole, to be used for being screwed into pull bar, is convenient to install with lathe.Connecting axle root connects the piece cylinder that rises, and the piece cylinder internal diameter that rises is identical with workpiece to be processed external diameter, and the barrel of the piece cylinder that rises is evenly cut into the decile piece that rises, and a circular hole of each otch bottom processing, with stretching of the piece that guarantees to rise.In the axle center, piece cylinder bottom of rising, a double-screw bolt is set, on double-screw bolt, is going here and there the core that rises.The core that rises becomes conical cap structure, and the piece cylinder top of the rising piece inwall that rises is also pyramid type structure, and core coordinates with rising.Workpiece to be processed suit is risen outside piece, by nut inside rotation on screw rod, inwardly hold out against the core that rises, drive the piece expansion of rising, and then workpiece inwall is held out against, indeformable while processing thin outer surface of workpiece.
The beneficial effects of the utility model are: not only can be easy to operate, improve machining accuracy and quality, and be applicable to the inside and outside wall processing of thin cylinder.
Accompanying drawing explanation
The utility model has accompanying drawing 4 width.
Fig. 1 is the utility model inner surface machining mould schematic diagram.
Fig. 2 is the core schematic diagram that rises of the utility model outer surface machining mould.
Fig. 3 is the stereogram of the utility model outer surface machining mould.
Fig. 4 is the profile of the utility model outer surface machining mould.
Sequence number explanation in figure, 1. base chuck, 2. gland, 3. circular port, 4. positioning spigot groove, 5. bolt hole, 6. press mouthful, 7. support bar, 8. rise core, 9. rise piece, 10. rise piece cylinder, 11. connecting axles, 12. bracket cup holes, 13. double-screw bolts, 14. nuts, 15, circular hole.
The specific embodiment
Below in conjunction with specific embodiment explanation the utility model, the first car inner surface of this workpiece, first selects inner surface machining mould; Comprise two parts: base chuck 1, gland 2, in the middle of base chuck 1, there is circular port 3, the circular orientation seam groove 4 that circular port 3 arranged outside are corresponding with workpiece lower surface diameter of axle size, at three bolts hole 5 of positioning spigot groove 4 arranged outside;
Gland 2 comprises sleeve, presses mouth 6, support bar 7, the internal diameter of sleeve and height are corresponding with workpiece, press mouth 6 to cover in workpiece top annular upper surface, the corresponding bolt of 1 three bolts hole 5 of support bar 7 end settings and base chuck is tight, make fixedly clamping of workpieces of gland 2, then integral installation is processed on lathe spindle.
During this workpiece car outer surface, select outer surface machining mould; Comprise the core 8 that rises, the piece 9 that rises, the piece cylinder 10 that rises, connecting axle 11, bracket cup hole 12, double-screw bolt 13, nut 14, connecting axle 11, the piece cylinder 10 that rises, the piece 9 that rises are structure as a whole, connecting axle 11 connects lathe chucks, by end to root chap gradually, to form interference fit with lathe spindle, axle center, connecting axle end arranges bracket cup hole 12, to be used for being screwed into pull bar, is convenient to install with lathe.Connecting axle 11 roots connect the piece cylinder 10 that rises, and piece cylinder 10 internal diameters that rise are identical with workpiece to be processed external diameter, and the barrel of the piece cylinder that rises is evenly cut into the eight equal parts piece 9 that rises, and a circular hole 15 of each otch bottom processing, with stretching of the piece that guarantees to rise.In piece cylinder 10 axle center, bottom of rising, a double-screw bolt 13 is set, on double-screw bolt 13, is going here and there the core 8 that rises.The 8 one-tenth conical cap structures of core that rise, piece cylinder 10 tops of rising piece 9 inwalls that rise are also pyramid type structures, core 8 coordinates with rising.Workpiece to be processed suit is risen outside piece 9, by nut 14 inside rotation on screw rod, inwardly hold out against the core 8 that rises, drive piece 9 expansions of rising, and then workpiece inwall is held out against, indeformable while processing thin outer surface of workpiece.
