The operation of the electroplanting device of present embodiment below will be described.
Be installed on the work erecting bed 17 on the crankcase surface 110 that has under the vertical sensing with cylinder head 104 bonded cylinder body 100.At this moment, the steady brace 14 of work erecting bed 17 is fitted to the dowel hole 115 of cylinder body 100, therefore, cylinder body 100 is positioned, and the latch 15 of work erecting bed 17 by the close property of liquid fit within oil duct 112 in the cylinder body 100, in the end of crankcase side.In this state, crankcase surface 110 contact work erecting beds 17.
Then, cylindrical electrode 12 is inserted in the cylinder-bore 103 of cylinder body 100, and first containment member 11 contacts with the valve seat 109 of the valve seat 108 that is attached to cylinder head 104, and the following end in contact of second containment member 16 and cylinder inner peripheral surface 106.

Afterwards, closed cell 20 keeps anchor clamps 18 to slide with respect to work, and is installed in the peristome 111 in the oil duct 112 of the 3rd containment member 19 closed cylinder body 100 on the closed cell 20.According to above-mentioned successive operation, be installed on the electroplanting device 10 with cylinder head 104 bonded cylinder body 100.
Being installed in cylinder body 100 under the state of electroplanting device 10, is that the cylinder inner peripheral surface 106 of cylinder body 100 is implemented pre-electroplating processes and clean continuously.On the other hand, be installed in cylinder body 100 under the state of another electroplanting device 10, carry out electroplating processes and clean for the cylinder inner peripheral surface 106 of cylinder body 100 equally continuously.
In pre-electroplating process, implement Japanese Patent Application and disclose 2005-206948 number described anode electrolysis etch processing (anodic electrolytic etching treatment).In the anode electrolysis etch was handled, the electrolytic solution of use such as phosphoric acid, sulfuric acid and thionamic acid was as treatment solution.By suction operation, treatment solution flows to inter-process liquid passage 21 from external treatment liquid passage 22.In this state, the power subsystem that electric energy is never shown is fed to cylindrical electrode 12 and cylinder body 100, makes cylindrical electrode 12 become negative pole and cylinder body 100 becomes positive pole.Therefore, handle by etch (corrosion), the cylinder inner peripheral surface 106 of cylinder body 100 stands the surface roughening operation, and the set effect of uneven surface (anchor effect) can increase the tack of electroplating film to cylinder inner peripheral surface 106.
On the other hand, in electroplating process, by using and the pre-similar electroplanting device 10 of electroplating process, by treatment solution and the power on condition of selecting to be scheduled to, electroplating film is formed on the cylinder inner peripheral surface 106 of cylinder body 100, still, and in this electroplating processes, the flow direction of treatment solution in the treatment solution passage is inverted, and positive and negative electrode also becomes opposite with positive and negative electrode in the above-mentioned pre-electroplating process.Particularly, in electroplating process, treatment solution treatment solution passage 21 internally flows to external treatment liquid passage 22 and switches on, and cylinder body 100 becomes negative pole thereby cylindrical electrode 12 becomes positive pole.
The reason that the treatment solution passage of pre-electroplating process (anode electrolysis etch processing) and electroplating process differs from one another is, pre-electroplating process needs alap treatment solution flow velocity, thereby the temperature of reaction of the cylinder inner peripheral surface 106 by improving cylinder body 100 promotes etch to handle.Therefore, as a kind of method that treatment solution is contacted with cylinder inner peripheral surface 106, treatment solution flows to inter-process liquid passage 21 from external treatment liquid passage 22.On the other hand, the treatment solution flow velocity that electroplating process is need be on cylinder inner peripheral surface 106 high as far as possible, thus the film that improves electroplating film forms speed.Therefore, treatment solution internally treatment solution passage 21 flow to external treatment liquid passage 22.
Finish after each of pre-plating and electroplating process, stop supplies treatment solution and electric energy, and to being installed in the cylinder body enforcement cleaning course on the electroplanting device 10.Do not have in cylinder body 100 in the configuration of oil duct 112, by the water pump that operation does not show, cleaning water is fed to inter-process liquid passage 21 and external treatment liquid passage 22 by the water tank that directly never shows, thus the cylinder inner peripheral surface 106 of cleaning cylinder body 100.In cylinder body 100, be formed with in the configuration of oil duct 112, by oil duct 112 supply cleaning water.
Promptly, after finishing pre-plating or electroplating, water pump begins by tube unit cleaning water to be fed to latch 15 and oil duct 112 from water tank, continue to make cleaning water to flow to external treatment liquid passage 22 and inter-process liquid passage 21 then, thereby clean oil duct 112 and cylinder inner peripheral surface 106 simultaneously from oil duct 112.The exhausted cleaning water is guided the treatment solution case that does not show by external treatment liquid passage 22 and inter-process liquid passage 21.It is identical with the water-content of the treatment solution evaporation that causes by heating that the amount of the cleaning water that will be supplied this moment is adjusted to.Therefore, the strength of fluid of treatment solution case remains unchanged.After finishing cleaning course, switch the valve that does not show, and air is supplied to oil duct 112, thereby discharges the cleaning water that accumulates in the oil duct 112.
Pre-electroplate or electroplating processes in, cleaning water is full of from tube unit to latch 15 zone.Therefore, although treatment solution enters oil duct 112, owing to the pressure of cleaning water for latch 15, treatment solution can not enter in latch 15 and the tube unit yet.

(1) first containment member 11 that is used to seal the combustion chamber 105 that is communicated with the cylinder-bore 103 of cylinder body 100 is attached to the top of cylindrical electrode 12, thereby is set in the combustion chamber 105.Therefore, the reactant gases that produces in the process of pre-plating or plating cylinder inner peripheral surface 106 can be stayed in the combustion chamber 105, thereby prevents to stay in the upper area 117 of cylinder-bore 103.Therefore, cylinder-bore 103 is full of treatment solution fully, and can form good electroplating film in the entire cylinder of cylinder-bore 103 on the perimeter surface 106.
Especially, under the situation of the pre-electroplating process of handling by the anode electrolysis etch that wherein produces very a large amount of reactant gasess, reactant gases can be accumulated in the combustion chamber 105, thereby can form good electroplating film near the entire cylinder the upper end 116 that comprises cylinder inner peripheral surface 106 on the perimeter surface 106.
In addition, because slip on the internal surface 114 of combustion chamber 105 of piston, so there is no need to electroplate internal surface 114.Therefore, even because problem can not take place in reactant gases gathering and do not form electroplating film on internal surface 114 in combustion chamber 105 yet.
(2) first containment member 11 that is used for the combustion chamber 105 of blanket gas cylinder cap 104 contacts with valve seat 109 pressure of the valve seat 108 that is installed to cylinder head 104, thus direct seal valve seat surface 109.Therefore, pre-electroplate or electroplating process in, can prevent that treatment solution from contacting with valve seat 109, thereby prevent the corrosion at interface between the corrosion of valve seat 108 and cylinder head 104 (aluminum) and the valve seat 108 (iron material).Therefore, can prevent to cause coming off or fault that heat conductivity descends effectively such as valve seat 108.
(3) upper end 24 of cylindrical electrode 12 is positioned as with the upper end 116 of the cylinder inner peripheral surface 106 of cylinder body 100 and aligns, perhaps 105 internal ratios upper end, the 116 more close cylinder head (104) in the combustion chamber.Therefore, in pre-electroplating process, may strengthen the galvanized tack on the perimeter surface 106 near the entire cylinder the upper end 116 that comprises cylinder inner peripheral surface 106.In addition, in electroplating process, can near the entire cylinder the upper end 116 that comprises cylinder inner peripheral surface 106, form good electroplating film on the perimeter surface 106.
(4) because the cleaning water in the treating processes is fed to external treatment liquid passage 22 and inter-process liquid passage 21 by the latch 15 of oil duct 112 from be positioned at work erecting bed 17 by cylinder body 100, so may clean oil duct 112 and cylinder inner peripheral surface 106 reliably.Therefore, can prevent because the tack that remains in after the pre-electroplating process in the caused electroplating process of treatment solution in the oil duct 112 descends, and also can prevent since pre-electroplate or electroplating process after remain in caused oil duct 112 corrosion of treatment solution in the oil duct 112.
