Abstract
The utility model provides a piston for a two-way piston cam plate type compressor, which comprises a piston body, wherein, the piston body is provided with an outer surface, and the outer surface ofthe piston body includes a lubricating layer, an oxide film layer and a seal layer. When conducting reciprocating motion inside the piston hole of the cylinder block of the compressor, the piston exhibits such good traits as lubricating property, wear resisting property and corrosion resisting property.
Description
Technical field
The utility model relates to automobile air conditioner compressor, especially relates to the piston of bidirectional piston formula slant plate type compressor.
Background technique
In automobile air conditioning system, adopt the bidirectional piston oblique tray type compressor widely, and bidirectional piston places in the interior piston hole of compressor cylinder block.Better for the performance and the durability of compressor, the surface of contact of the piston hole hole wall in the outer surface of piston and the cylinder block need have good lubricity, wear resistance.
Available technology adopting is spraying teflon coating to improve lubricity and the wear resistance between piston and the piston hole hole wall on the outer circumferential face of the piston that has machined, and before the spraying teflon coating, earlier outer surface of piston is carried out shot-peening, and then repeat four times the spraying polytetrafluoroethylene, it will be dried after each spraying is finished.After the spraying polytetrafluoroethylene is finished, carry out the one-step solidification baking, last outer surface also will be carried out the size that requires that grinding reaches piston, can finish the manufacturing of piston like this.Yet prior art is to the processing method complex process of piston, and process step is many, wastes man-hour, has increased the processing cost of piston, thereby has influenced the Economy of compressor complete machine.
Summary of the invention
Be to solve the problems referred to above of prior art, the utility model provides a kind of piston of bidirectional piston oblique tray type compressor, and this piston has good lubricating property, wear-resisting property and corrosion resistance during to-and-fro motion in the piston hole of compressor cylinder block.
For realizing this purpose, the utility model provides a kind of piston of bidirectional piston oblique tray type compressor, comprises piston only, and described piston only has outer surface, and wherein, described piston only outer surface comprises lubricating layer, oxidation film layer and confined bed.
Preferably, described piston only is made by aluminum alloy material.
Preferably, described oxidation film layer is the aluminium oxide rete.
Preferably, described confined bed is made of the nanometer anti-friction agent.
Preferably, described lubricating layer is made of the solvent that contains lubricated composition.
Compare with the piston of prior art spraying teflon coating, piston with the utility model structure reduces the piston face treatment step, and technology is simple, reduced cost for manufacturing compressor, and made piston have good wear resistance, lubricity and corrosion resistance.
Brief description of drawings
Following with reference to accompanying drawing, preferred embodiment of the present utility model is made detailed description so that design of the present invention and characteristics clearly are described, wherein:
Fig. 1 is the plan view of the piston of the utility model bidirectional piston oblique tray type compressor;
Fig. 2 is the sectional view of piston shown in Figure 1; And
Fig. 3 is the surperficial organigram of the utility model piston.
Embodiment
Fig. 1 and Fig. 2 show the plan view and the sectional view of the piston of the utility model bidirectional piston oblique tray type compressor, and piston 1 of the present utility model adopts aluminum alloy material to make.Piston has good wearability in order to make, lubricity and corrosion resistance, must carry out surface treatment to piston, and therefore piston of the present utility model comprises following structure: as shown in Figure 3, the outer surface 11 of the utility model piston comprises lubricating layer 111.After piston 1 is finished machining, the piston article that machines is immersed in the solvent that contains lubricated composition, contain multiple components in this lubricated solvent to form a lubricating layer 111 at piston 1 outer surface 11.Subsequently, anodizing is carried out on the piston article surface, make outer surface of piston form oxidation film layer 112, and oxidation film layer has higher hardness to improve the wear resistance of outer surface of piston greatly, concrete processing method for example can be that piston article is placed main body as anode is the electrolytic solution of sulfuric acid, utilizes electrolysis (can add some additives on request in the electrolytic solution) to make aluminum alloy material surface form the aluminum oxide film rete.Yet, the oxidized aluminum alloy rete is a kind of porous structure, has very high adsorption performance, aggressive medium in the compressor enters the thin layer hole easily and causes and pollute and the piston face friction factor is increased, therefore in the utility model, the aluminium oxide rete has also been carried out sealing to be handled, for example adopt a kind of nanometer anti-friction agent, suction-operated by the aluminium oxide rete is filled into anti-friction agent and forms confined bed 113 in the hole on the film reaching the effect of sealing porous structure, thereby prevents that the outer surface of piston friction factor from increasing.
