Abstract

A hard anode oxidation fixture for an aluminum piston of an internal combustion engine comprises a conical surface tray, a conical rubber sleeve and a locating ring; a three-section type through hole is formed in the conical surface tray in the axial direction, the diameter of the upper-section through hole is larger than the diameter of the lower-section through hole, and the middle-section through hole is a conical hole connected with the upper-section and the lower-section through holes; the locating ring is arranged inside the upper-section through hole of the conical surface tray, and the inner diameter of the locating ring is matched with the diameter of the piston; and the conical rubber sleeve consists of a conical section and a horizontal section and is arranged on the inner wall surface of the middle-section conical hole of the conical surface tray, and the horizontal section of the conical rubber sleeve is positioned between the conical surface tray and the locating ring. The hard anode oxidation fixture for the aluminum piston of the internal combustion engine can effectively realize hard oxidation treatment in the range of the whole top surface of the aluminum piston, and has good universal processability. One set of the fixture with locating rings with different diameters can meet the requirements for hard anode oxidation processing on the top surface of the aluminum piston of most medium and small sized internal combustion engines.

Description

Aluminium piston of IC engine hard anodizing anchor clamps
Technical field
The utility model relates to the clamp for machining that the aluminum alloy part hard anodizing is handled, and especially relates to a kind of clamp for machining of handling with aluminium piston of IC engine end face hard anodizing.
Background technology
The hard anodizing of aluminium piston-top surface is handled, and is to utilize the good heat-insulating property of its oxidation film layer to improve the recommendation technology of the heat-resisting serviceability of aluminium piston.The used clamp for machining of aluminium piston of IC engine hard anodizing equipment generally adopts O shape rubber sealing mode at present, it is by the mode at anchor clamps plane recessing dress O shape cushion rubber, O shape cushion rubber reaches the isolated oxidation tank liquor effect of sealing after flat compressed, encircle the non-oxidizing processing technology requirements in other positions such as bank, skirt section thereby satisfy at aluminium piston-top surface hard anodizing.The assembling condition of O shape rubber sealing oxidation clamp for machining is seen Figure of description 1.Such clamp for machining is because the sealing station of O shape cushion rubber, after hard anodizing is handled, can stay the non-oxide ring belt area of several mm wides in aluminium piston-top surface edge, can not realize fully the hard anodizing of the full end face scope of aluminium piston is handled, the heat-insulating property of aluminium piston-top surface edge is reduced.The aluminium piston of different cylinder diameters need cooperate the O shape cushion rubber of different diameter in addition, to the oxidation anchor clamps and the O shape cushion rubber of the multiple corresponding specification of the essential preparation of many kinds aluminium piston production.
The utility model content
The purpose of this utility model provides a kind of can effectively the realization hardening oxidation in the scope of the full top of aluminium-alloy piston is handled, and the good aluminium piston of IC engine hard anodizing anchor clamps of versatility.
This novel purpose is achieved in that a kind of aluminium piston of IC engine hard anodizing anchor clamps, is made up of conical surface pallet, taper gum cover and set ring; Conical surface pallet is along there being a syllogic through hole on its axis direction, the epimere through-hole diameter is greater than the hypomere through-hole diameter, and the stage casing through hole is the tapered hole that is connected mutually with upper and lower section through hole; Set ring is arranged in the epimere through hole of conical surface pallet, and the taper gum cover of being made up of a conical section and a horizontal section is arranged on the inner-wall surface of stage casing tapered hole of conical surface pallet, and the horizontal section of taper gum cover is between conical surface pallet and set ring.
The tapering of the stage casing tapered hole of above-mentioned conical surface pallet and the conical section of taper gum cover is 30 degree or is 45 degree.
The material of above-mentioned conical surface pallet and set ring is a nylon 66, and the material of taper gum cover is a silicon rubber.
Compared with prior art, this novel beneficial effect is:
1, improves the processing quality of the hard anodizing processing of aluminium piston
The aluminium piston of IC engine end face hard anodizing clamp for machining that this is novel; replace O shape cushion rubber flat seal with taper gum cover conical surface seal; because the taper gum cover is to contact with aluminium top land periphery; vacant aluminium piston-top surface position; conical surface pallet is identical with the tapering of taper gum cover; can select 30 degree or 45 degree for use; the taper gum cover covers on the conical surface pallet; aluminium top land periphery to be processed contacts with the gum cover conical surface and compresses; utilize the gum cover superior elasticity to reach the effect of the isolated oxidation tank liquor of sealing; the full end face scope of piston is carried out hard anodizing processing; and all the other positions of aluminium piston obtain effectively anti-plating protection, can realize the hard anodizing processing of the full end face scope of aluminium piston.
2, anchor clamps processing universal performance is better
Set ring is interchangeable formula (under same external diameter situation, the set ring internal diameter can have a series of different inner diameters), the general excellent processability of anchor clamps.Such clamp for machining is overlapped in preparation one, only need select to change the set ring of different inner diameters, can satisfy most middle-size and small-size aluminium piston of IC engine end face hard anodizing processing request.

Embodiment
Fig. 2 illustrates, and basis is novel to be made up of conical surface pallet 1, taper gum cover 2 and set ring 3; Conical surface pallet 1 is along there being a syllogic through hole on its axis direction, the epimere through-hole diameter is greater than the hypomere through-hole diameter, and the stage casing through hole is the tapered hole that is connected mutually with upper and lower section through hole; Set ring 3 is arranged in the epimere through hole of conical surface pallet 1, and the taper gum cover of being made up of a conical section and a horizontal section 2 is arranged on the inner-wall surface of stage casing tapered hole of conical surface pallet 1, and the horizontal section of taper gum cover 2 is between conical surface pallet 1 and set ring 3.Set ring internal diameter and piston diameter match.The tapering of the stage casing tapered hole of conical surface pallet 1 and the conical section of taper gum cover 2 is 30 degree or is 45 degree.The material of conical surface pallet 1 and set ring 3 is a nylon 66, and the material of taper gum cover 2 is a silicon rubber.
Among Fig. 1, existing anchor clamps are made up of plane pallet 10 and O shape cushion rubber 20.Aluminium piston 30 to be processed places on the O shape cushion rubber.Referring to Fig. 3, cylinder pressing plate 5 places aluminium piston 4 tops, and conical surface pallet 1 places above the hydrojet groove 6; Mouth spray is (the taper gum cover is the rubber cushion that a thickness equates) on through hole bottom (the being the hypomere through hole) opening of conical surface pallet.
