Description
Technical field
The utility model relates to a kind of electroplanting device, particularly a kind of internal combustion engine bearing axle sleeve electroplating system.
Background technology
Oil engine is a kind of power machine, and it is by making fuel burn at machine intimate, and the heat energy of being released directly is converted to the Thermal Motor of power.Sensu lato oil engine not only comprises stroke piston combustion engine, rotary engine and free piston engine, also comprise the internal combustion turbine of rotary vane type, jet engine etc., but usually said oil engine refers to piston type internal combustion engine.Piston type internal combustion engine is the most general with reciprocating piston type.Piston type internal combustion engine is by fuel and air mixed, and at its combustor inner cylinder, the heat energy discharged makes the combustion gas producing High Temperature High Pressure in cylinder.Combustion gas is expanded and is promoted piston work done, then mechanical work is exported by toggle or other mechanisms, drives follower work.Common are diesel engine and petrol motor, by being converted into mechanical energy by interior, is energy in being changed by acting.
For the bearing in internal combustion engine part, axle sleeve etc., plating one deck antifriction metal coating on the working face requiring its inner sleeve, outer peripheral surface has not then allowed coating, otherwise can centre-height be affected, impact assembling, traditional working method is: utilize one deck wrapped with insulation on the surface of outer ring, make inner ring plating one deck coating like this, and coating is not with in outer ring.But adopt aforesaid method carrying out, in the process of producing, not only wasting time and energy, and easily produce easy crossed contamination, staff finds how many outer rings all can plate coating simultaneously, and outer ring is once be covered with coating, need many unfavorable factors such as artificial sand removes again, inconvenience very.
Utility model content
The technical problems to be solved in the utility model is to provide one and can be good at preventing outer ring from covering coated internal combustion engine bearing axle sleeve electroplating system.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of internal combustion engine bearing axle sleeve electroplating system, and its innovative point is: comprise electrolytic plating pool, anode bar, axle sleeve, auxiliary cathode, hanger and electroplating rectifier;
Described hanger is positioned at electrolytic plating pool, in hanger, be mounted with axle sleeve, between hanger and electrolytic plating pool, be also provided with an auxiliary cathode;
Described axle sleeve is horizontally placed in hanger, is inserted with a right cylinder anode bar at the centre portions of axle sleeve, and the two ends up and down of anode bar all exceed the two ends up and down of axle sleeve;
Described auxiliary cathode is cylindrical netted;
Described plate commutator one has two, and be respectively rectifier A and rectifier B, the positive pole of rectifier A and rectifier B is all connected with anode bar, and the negative pole of rectifier A is connected with product, and the negative pole of rectifier B is connected with auxiliary cathode.
The utility model has the advantage of: by setting up an auxiliary cathode between the outer wall and the inwall of electrolytic plating pool of hanger, when electroplating bearing or axle sleeve, ensure that the inwall of axle sleeve is equal with the voltage of outer wall, then can ensure that axle sleeve outer wall is both without coating, be not corroded again, both be effective, time saving and energy saving again.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of internal combustion engine bearing axle sleeve electroplating system of the present utility model.
Embodiment
Schematic diagram is as shown in Figure 1 known, and internal combustion engine bearing axle sleeve electroplating system of the present utility model comprises electrolytic plating pool 4, anode bar 2, axle sleeve 5, auxiliary cathode 1, hanger 3 and electroplating rectifier.
Hanger 3 is positioned at electrolytic plating pool 4, is mounted with axle sleeve 5 in hanger 3, is also provided with an auxiliary cathode 1 between hanger 3 and electrolytic plating pool 4.
Axle sleeve 5 is horizontally placed in hanger 3, is inserted with a right cylinder anode bar 2 at the centre portions of axle sleeve 5, and the two ends up and down of anode bar 2 all exceed the two ends up and down of axle sleeve 5.
Auxiliary cathode 1 is cylindrical netted.
Electroplating rectifier one has two, is respectively rectifier A and rectifier B, and the positive pole of rectifier A and rectifier B is all connected with anode bar 2, and the negative pole of rectifier A is connected with product, and the negative pole of rectifier B is connected with auxiliary cathode 1.
Carrying out in the process of electroplating, by the positive pole of rectifier A and rectifier B all with anode bar 2 above, the negative pole tipping of rectifier A has on the hanger 3 of axle sleeve 5 makes negative electrode, rectifier B is connected with auxiliary cathode 1, wherein, anode bar 2 is inserted in the middle of axle sleeve 5 by specific hanger, even to ensure the inner thickness of coating of axle sleeve, after the current settings of electroplating rectifier A is good, observe voltage V1, V1 is the voltage of the inwall of axle sleeve 5, open another electroplating rectifier B again, main detection voltage V2, V2 is the voltage of auxiliary cathode, then V2=V1 is controlled well, after in axle sleeve 5, wall coating size reaches, take out product, then can ensure that axle sleeve outer wall is both without coating, be not corroded again, both be effective, time saving and energy saving again.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
