Specific embodiment
In order that architectural feature of the invention and the effect reached have a better understanding and awareness,
Spy's preferred embodiment and cooperation detailed description, are described as follows：
Refering to Fig. 1, it is the schematic diagram of the electrochemical machining apparatus of the first embodiment of the present invention.As schemed
Shown, electrochemical machining apparatus of the invention are single comprising an electrolyte storage tank 10, the rotation of an electrode 12,
First 14, one power-supply unit 16 and a traveling units 18.Electrode 12 and a workpiece 20 vertical (Z-direction)
Electrolyte storage tank 10 is placed in, and electrode 12 corresponds to workpiece 20 and sets, between the two with a spacer
From electrolyte storage tank 10 is simultaneously equipped with electrolyte 11, i.e., electrode 12 is located at electrolyte 11 with part workpiece 20
In.In one embodiment of the invention, workpiece 20 is cylindric, and electrode 12 is a plate electrode, its surface
It is a plane, i.e., the surface profile of workpiece 20 and does not correspond to the profile of screw thread.The sun of power-supply unit 16
Pole is respectively coupled to workpiece 20 and electrode 12 with negative electrode, to supply power supply to electrode 12 and workpiece 20.Yu Benshi
Apply in example, the anode of power-supply unit 16 is coupled to workpiece 20 via rotary unit 14.
Rotary unit 14 is fixed in one end of workpiece 20, and rotary unit 14 drives workpiece 20 to rotate, so
The electrolyte flow field of the periphery of workpiece 20 can be in a spiral vortex state, and such electrode 12 carries out electricity to workpiece 20
During chemical process, the surface of workpiece 20 can form screw thread 21.Additionally, rotary unit 14 is arranged at list of dividing a word with a hyphen at the end of a line
Unit 18, traveling units 18 are rotated unit 14 in vertical (Z axis) direction movement, with movable part workpiece 20
Into or out electrolyte storage tank 10.
When workpiece 20 carries out electrical-chemistry method, it is under carrying current state, that is, current density is not
Can be when voltage rising and rising, as shown in Fig. 2 the surface of workpiece 20 will produce with the intersection of electrolyte 11
One sticky liquid interface layer, it is sticky layer 30 (viscous layer), its sun for including the dissolving of workpiece 20
Anion in ion and electrolyte 11, the resistance of the resistance ratio electrolyte 11 of sticky layer 30 is big, so sticky
Layer 30 is the non-conductor of electricity.The present invention by the rotational workpieces 20 of rotary unit 14, so under certain rotating speed,
The electrolyte flow field of the periphery of workpiece 20 is subject under the influence of the rotation of workpiece 20, and electrolyte flow field can be in a spiral shell
Bumpy flow (spiral vortex) state, such sticky layer 30 can be influenceed by electrolyte flow field and is in spiral shell
Rotation shape.
Accept above-mentioned, the integral thickness of spiral sticky layer 30 is to differ, spiral helicine sticky
The thinner thickness of the Luo Gu of layer 30, electric current is easier to pass through, therefore the Luo Gu of the sticky layer 30 of the correspondence of workpiece 20
Can be subject to larger current, the i.e. dissolution velocity of this position of workpiece 20 very fast at position, comparatively, spiral shell
The thickness for revolving the Luo Feng of the sticky layer 30 of shape is thicker, and the electric current so by the Luo Feng of sticky layer 30 is relatively small,
The dissolution velocity of the correspondence position of workpiece 20 is slower.For these reasons, the surface of workpiece 20 can be subject to difference
The electric current of intensity, and current strength is the thickness of the spiral helicine sticky layer 30 of correspondence, such workpiece 20 carries out electricity
During chemical process, the surface of workpiece 20 is not to be uniformly dissolved, but the spiral helicine sticky layer 30 of correspondence,
Form screw thread 21.As shown in figure 1, be formed at the upper tightly lower sparse of screw thread 21 of workpiece 20, i.e., near workpiece 20
The screw thread 21 of end is relatively dredged, so representing that screw thread 21 is not equidistant.The present invention can be adjusted according to use demand
Whole machined parameters, and adjust the spacing of screw thread 21.
As shown in the above description, the present invention does not correspond to the electrode of the profile of screw thread 21 using surface profile
12 pairs of workpiece 20 carry out electrical-chemistry method, you can form screw thread 21 in the surface of workpiece 20, the surface of electrode 12
Profile need not need the profile of correspondence screw thread 21 as commonly used electrode, can so reduce the design of electrode 12
With process time, and reduce the previous operations before electrical-chemistry method.Additionally, being adjusted by electrical-chemistry method
Machined parameters can adjust the profile of screw thread 21, such as angle of thread, the depth of thread or flight pitch, example
The rotating speed or machining voltage intensity of rotational workpieces 20 are such as adjusted, the angle of screw thread 21 can be adjusted；Adjustment adds
Work voltage strength or process time, the depth of screw thread 21 can be adjusted.
Also referring to Fig. 3, it is the flow chart of the method for electrochemical machining of one embodiment of the invention.
As illustrated, step S1, there is provided workpiece 20 and electrode 12, electrode 12 correspond to workpiece 20 and sets, electrode
12 profile non-corresponding in the profile of screw thread 21, and as shown in step S3, there is provided electrolyte 11 is in workpiece 20
There is spacing distance between electrode 12, and between electrode 12 and workpiece 20.Afterwards, step S5 is carried out, work is rotated
Part 20, so that the periphery electrolyte flow field of workpiece 20 reaches spiral vortex state；Then, as shown in step S7,
Electrical-chemistry method is carried out, screw thread 21 is formed in the surface of workpiece 20.As shown in the above description, electricity of the invention
Chemical processes order about the electrolyte flow field of the periphery of workpiece 20 helically turbulent state, and carry out electrochemistry
Processing, can so form screw thread 21 in the surface of workpiece 20.
