See also Fig. 4 A to Fig. 4 E, it is the using state figure of the electrode structure of the first embodiment of the present invention; As shown in the figure, when using electrode structure 1 pair of workpiece 2 to carry out electrical-chemistry method processing procedure, as shown in Figure 4 A, workpiece 2 is set up in an electrolytic cell 4, the main shaft 51 of processing machine 5 clamps and grips unit 13, and namely electrode body 12 is connected to processing machine 5, with the top making electrode structure 1 be positioned at workpiece 2.In the present embodiment, a loading plate 41 is arranged in electrolytic cell 4, to carry workpiece 2.The present embodiment further comprises at least one stationary fixture 43, and it is arranged at loading plate 41 and for fixation workpiece 2.
The material of electrode structure 1 removes before electrode unit 100 carries out electrical-chemistry method processing procedure, and first carry out contraposition program, processing machine 5 orders about electrode structure 1 to the prefabricated hole 21 being positioned at workpiece 2.Contraposition program means that material removes a center line of the prefabricated hole 21 of the axis alignment pieces 2 of electrode unit 100.After completing contraposition program, as shown in Fig. 4 B figure, the main shaft 51 of processing machine 5 drives electrode structure 1 axially to move toward workpiece 2 along it, makes material remove electrode unit 100 and enters in prefabricated hole 21.When material removes predetermined machining area 211 (i.e. the inner surface of hole 21) of processing district (namely material removes the surface 120 of the axis of electrode unit 100) corresponding prefabricated hole 21 of electrode unit 100, the main shaft 51 stop band moving electrode structure 1 of processing machine 5 moves along its axis.So, an anode 31 of a power-supply unit 3 connects workpiece 2, a negative electrode 32 connecting electrode structure 1 of power-supply unit 3.
As shown in Figure 4 C, one electrolyte supplying device 6 provides in electrolyte 61 a to electrolytic cell 4 through a transfer conduit 63, electrolyte 61 can be provided in prefabricated hole 21, and is positioned at the inner surface (predetermined machining area 211) of prefabricated hole 21 and material removes between electrode unit 100.In the present embodiment, transfer conduit 63 injects electrolyte 61 from the bottom of electrolytic cell 4, and jet electrolytic liquid 61 is in prefabricated hole 21, and electrolyte 61 like this can flow from the bottom of prefabricated hole 21 toward top.While supply electrolyte 61 to prefabricated hole 21 and material remove between electrode unit 100, power-on feeding unit 3 and supply power supply, material like this removes electrode unit 100 and carries out electrical-chemistry method processing procedure to predetermined machining area 211, processing process is removed to carry out material to predetermined machining area 211, and expanding the aperture of prefabricated hole 21, in figure, dotted portion is the part that predetermined machining area 211 is removed.
The axial distance that the axial distance that the material of the present embodiment removes electrode unit 100 is more than or equal to the predetermined machining area 211 of workpiece 2 is good, the processing district making material remove electrode unit 100 can contain predetermined machining area 211 completely, material like this remove electrode unit 100 can equably to predetermined machining area 211 carry out material remove processing process.
To complete after material removes processing process to predetermined machining area 211 when material removes electrode unit 100, i.e. powered-down feeding unit 3, removes electrode unit 100 to stop material and continues to carry out electrical-chemistry method processing procedure to predetermined machining area 211.It is circular hole that the hole 21 of the present embodiment removes after processing process through material, it is mainly a cylinder because material removes electrode unit 100, so material removes the cross sectional shape of electrode unit 100 for circular, so remove electrode unit 100 through material and process the cross sectional shape of the hole 21 after processing for circular, and allow hole 21 become circular hole.Certain hole 21 also can become an irregularly-shaped hole by material removes processing process, the cross sectional shape system respective material of hole 21 removes the cross sectional shape of electrode unit 100, so material removes the cross sectional shape of electrode unit 100 under abnormity (non-circular), through material remove electrode unit 100 process process after the cross sectional shape of hole 21 be abnormity (non-circular), namely hole 21 like this becomes irregularly-shaped hole.
The above-mentioned prefabricated hole 21 originally not yet carrying out the workpiece 2 of electrical-chemistry method processing procedure is use general machining to be formed, namely the procedure for processing of high accuracy and low surface roughness must do not used especially on workpiece 2 to form prefabricated hole 21, the predetermined machining area 211 removing the prefabricated hole 21 of electrode unit 100 pairs of workpiece 2 because of later use material carries out electrical-chemistry method processing procedure, so can revise the aperture of prefabricated hole 21, to reach predetermined aperture, also allow prefabricated hole 21 reach high accuracy and surface reaches great surface quality simultaneously, so do not need additionally to carry out burr removing process to predetermined machining area 211.
When material remove electrode unit 100 complete material remove processing process after, first powered-down feeding unit 3, the main shaft 51 of processing machine 5 drives electrode structure 1 axially to move toward workpiece 2 along it again, as shown in Fig. 4 D figure, make the predetermined machining area 211 of the corresponding hole 21 in the processing district of figure line electrode unit 102, those conductive pattern lines 1023 referring in particular to figure line electrode unit 102 must corresponding predetermined machining area 211.Now, the main shaft 51 stop band moving electrode structure 1 of processing machine 5 moves.As shown in Fig. 4 E figure, then power-on feeding unit 3, the predetermined machining area 211 of those conductive pattern lines 1023 pairs of holes 21 of figure line electrode unit 102 carries out electrical-chemistry method processing procedure, to carry out figure line processing process to the predetermined machining area 211 of hole 21, and then multiple figure lines 22 of formation those conductive pattern lines 1023 corresponding are in the predetermined machining area 211 of hole 21.As illustrated in figure 4f, those figure lines 22 are namely formed in the inner surface of hole 21.After figure line electrode unit 102 completes figure line processing process, first powered-down feeding unit 3, then drive electrode structure 1 to exit from the hole 21 of workpiece 2, namely complete multiple processing process of electrical-chemistry method processing procedure.
From the above, the electrode structure 1 of the present embodiment only must carry out a contraposition program, the difference processing process of electrical-chemistry method processing procedure sequentially can be carried out to workpiece 2, such as: material removes processing process and figure line processing process, in process like this, reduce the number of times changed other electrode structure and carry out contraposition program, and effectively reduce overall process time, also can promote overall machining accuracy.
Refer to Fig. 5 and Fig. 6, it is using state figure and the profile of the electrode structure of the third embodiment of the present invention; As shown in the figure, the electrode structure 1 of the present embodiment is different from the first embodiment to be, the electrode structure 1 of the present embodiment more comprises an insulating unit 101, insulating unit 101 is arranged in material and removes between electrode unit 100 and figure line electrode unit 102, namely be arranged between two adjacent electrode units, and insulating unit 101 comprises a body and an insulating barrier 1011.The body of the present embodiment is be positioned at material to remove electrode body 12 between electrode unit 100 and figure line electrode unit 102, and insulating barrier 1011 is formed at the surface of body, and namely insulating barrier 1011 is positioned at the surface 120 of electrode body 12.The axial distance system that the material be wherein arranged in before insulating unit 100 removes electrode unit 100 is less than the axial distance of the predetermined machining area 211 of workpiece 2.
When the predetermined machining area 211 of electrode structure 1 pair of workpiece 2 carries out electrical-chemistry method processing procedure, material removes before electrode unit 100 do not enter the hole 21 of workpiece 2, first start power-supply unit 3, the main shaft 51 of processing machine 5 drives electrode structure 1 to continue axially to move in the hole 21 of workpiece 2 along it, and material removes electrode unit 100 and removes processing process along with the movement of electrode structure 1 to the material that the predetermined machining area 211 of the hole 21 corresponding with it carries out electrical-chemistry method processing procedure.When material remove electrode unit 100 along electrode structure 1 in hole 21, axially continue movement time, be arranged in material remove the insulating unit 101 after electrode unit 100 also along electrode structure 1 axially continue in hole 21 mobile, can be corresponding with the insulating barrier 1011 of insulating unit 101 so previously remove through material the predetermined machining area 211 processing process, insulating unit 101 like this can prevent from removing the predetermined machining area 211 of processing process by dispersion corrosion through material.When material remove electrode unit 100 to continue along the axis of electrode structure 1 mobile and by the hole 21 of workpiece 2 after, material remove electrode unit 100 namely complete to hole 21 carry out material remove processing process, the now main shaft 51 stop band moving electrode structure 1 of processing machine 5.
