Description
Technical field
The present invention relates to a kind of equipment and method of deburring, particularly a kind of Electrochemic equipment for removing burr and method that is applicable to diesel motor cylinder.
Background technology
Diesel engine is when work, lubricating oil is by oil duct, oil groove staggered in cylinder body, flow into the oilhole on bent axle, camshaft hole intermediate bushing, then pass through to intersect the duct after entering bent axle, camshaft journal oilhole, be delivered at last as positions such as connecting rods, can play like this effect of lubricated connecting rod and connecting rod bearing shell.Have the situation of plastic deformation due to metal material, so after the oil-hole drill completion, the more residual smear metals of place meeting of (passing through mutually) are intersected in two holes, Here it is " burr ".In the engine cylinder-body oil circuit, burr can come off, and not only is related to the cleaning of oil circuit, also will directly affect the performance and used life of Diesel engine.Owing to having burr in the engine cylinder-body oil circuit, the lighter will affect the service life of engine, cause wearing and tearing aggravations, Cylinder sticking, the fault such as pull; Will there be serious potential safety hazard in severe one, directly jeopardize people's life.
Certainly, the method for deburring has a lot, such as the method for machinery, and the method for abrasive particle, abrasive material, the method for chemistry, method of heat energy etc.But for diesel motor cylinder, the mechanical epilation thorn easily produces the secondary burr; The burr removing method of abrasive particle, abrasive material, cleaning for the deburring part is had higher requirement, and not only abrasive particle easily blocks in long and narrow oil duct, and because the cylinder body part material is cast iron, meeting in cast iron " storage " abrasive material totally can not aggravate the wearing and tearing of driving member on the contrary if clean; The method of chemical deburring can also can cause corrosion to the position that does not need deburring; The method of heat energy deburring does not also have for engine cylinder-body at present can supply the main equipment of processing, and after passing through the heat energy deburring, piece surface easily produces oxidation; In addition, the also secondary assembling by engine of engine production manufacturer (first pre-assembled, trial run, then take apart and clean the burr that comes off then assembling) improves the cleannes of engine (particularly oil circuit), and operation is very numerous and diverse.Therefore these several traditional burr removal technologies all can not be applicable to the deburring problem of diesel motor cylinder well.
Summary of the invention
The purpose of this invention is to provide a kind of Electrochemic equipment for removing burr and method that is applicable to diesel motor cylinder, thereby by adopting the process principle of electrochemical deburring, remove effectively in cylinder body part main oil gallery, secondary oil duct, crankshaft hole, camshaft hole that all pass through mutually, intersect, the burr at oil groove position and make its former burr seamed edge that certain rounding be arranged.
The process principle of the electrochemistry that the present invention mainly adopts (electrolysis) deburring is to utilize metal to produce the electrochemical reaction phenomenon of anodic solution in the electrolysis working solution, thereby reaches the effect of deburring.
As shown in Figure 1: take workpiece as anode, tool-electrode is negative electrode, when force make the electrolysis working solution by the burr on workpiece and and the tool-electrode of particular design between very narrow and small gap simultaneously, short time is decomposition voltage in addition, at this moment on the burr of workpiece or the electric current on seamed edge part the most concentrated, current density is also maximum, thereby makes the very fast dissolved removal of burr, and corner angle are also rounded.
In the process of electrochemical deburring, workpiece is both relative fixed with tool-electrode, namely belongs to the method for electrochemical machining of fixed tool negative electrode.
In the process of electrochemical deburring, interelectrode reaction is very complex, and influence factor is more.Take the steel components electrochemical deburring as example, when adopting NaNo
3When being the electrolysis working solution for the aqueous solution of base, exist H in the electrolysis working solution
+, OH
-, Na
+, No
3 -Plasma, this moment, anode reaction was:
Under the external power effect, anode (being workpiece) surface:
Fe-3e-＞Fe
+++
Fe
++++30H
--＞Fe(OH)
3↓
The Fe (OH) that generates
3The electrolyte that sediment is flowed is taken away.
In ideal conditions, in electrochemical reaction process, anode metal (being workpiece) is constantly dissolved, the water consumption that is decomposed, thereby the concentration that makes electrolyte has certain variation, and other ion plays electric action in electrochemical reaction process, and itself can not consume.
The technical scheme that realizes the object of the invention is: for the process principle by the employing electrochemical deburring, effectively remove in cylinder body part main oil gallery, secondary oil duct, crankshaft hole, camshaft hole that all pass through mutually, intersect, the deburring at oil groove position and make its former burr seamed edge that certain rounding be arranged, the invention provides a kind of Electrochemic equipment for removing burr that is applicable to diesel motor cylinder, this equipment mainly is comprised of main frame, power control system, electrolysis working fluid system and side direction tool-electrode.Wherein, power control system can provide manually and automatic sequence is controlled to lathe, and processes for electrochemistry processing power source is provided; The electrolysis working fluid system can be by needing the position of Electrolyzed Processing that the electrolysis working solution is provided on the infusion path alignment part in tool-electrode.
Main frame comprises the travelling table parts, inside at the travelling table parts is provided with movable working platform, when the cylinder body part is located when being placed on workbench by the modes of two pin one sides, this workbench can be by mobile and the cylinder body part is moved into the machining area that is positioned on the travelling table parts; Be separately installed with the right side in the both sides of travelling table parts and move the mobile infeed mean of infeed mean and left side, wherein the right side is mutually vertical on horizontal plane with the moving direction of the workbench of travelling table parts with mobile direction with the mobile infeed mean in left side; In addition, at the machining area that is positioned on the travelling table parts, be separately installed with the side direction tool-electrode towards an end of machining area separately in the mobile infeed mean of the left and right sides, in the outside of side direction tool-electrode, shield components be installed.The travelling table that is equipped with like this can make the electrochemistry processing of cylinder body part carry out in machining area, and charge and discharge operations carries out in the operating area of machining area outside, makes the processing of part more convenient.
Due to the Diesel engine deburring equipment not only the clean characteristics of jagged removal also have simultaneously following characteristic:
(1) the physics and chemistry performance of processing rear-bank rotor housing part is constant.
(2) cylinder body part deburring position has selectively, and other position of cylinder body part is unaffected.
(3) the cylinder body part is not subjected to cutting force in process, and is fully indeformable.
