The inner hole of the positioning sleeve 3 is in clearance fit with the outer circle of the sheath 2 (the sheath 2 is made of insulating materials, electrolyte is allowed to leak out to a certain extent through the clearance) or in interference fit (the leakage of the electrolyte can be avoided through the fit mode), the direction is fixed through the cylindrical pin 12, a plurality of electrolysis water outlet holes are formed in the outer circle of the positioning sleeve 3, and the end face of the positioning sleeve 3 and the transition sleeve 5 are connected through the cylindrical pin 4 and then are used for determining the direction after being connected through the inner hexagon bolt 11. The prismatic locating pins 13 orient the part. The final function of the parts is to connect the directions of the parts and the cathode and complete the formation of the electrolytic complex convex plane in a matching way.
Before the electrolytic machining device for parts is used, a water inlet pipe 7, a transition sleeve 5, a first plug 6, a second plug 8, a third plug 9, an electrode plate 10, a cylindrical pin 4, an inner hexagonal bolt 11, a positioning sleeve 3, a cylindrical pin 12 and a sheath 2 are installed together to form a combined body; the external water inlet pipe is connected with the water inlet of the water inlet pipe 7, and the negative electrode of the power line is connected on the water inlet pipe 7.
When the part electrolytic machining device is used, the cushion block 1 is placed on a machine tool workbench, the part is placed on the cushion block 1, and then the assembled body which is assembled before is assembled on the part. At this time, the large outer circle of the part is matched with the middle hole of the sheath 2, and the upper end face of the part is attached to the first plug 6, the second plug 8 and the third plug 9.
During electrolytic processing, firstly, electrolyte is introduced into a water inlet of the water inlet pipe 7 and flows out from a water outlet hole of the positioning sleeve 3, and then a direct current power supply of an electrolytic machine tool is started, so that electrolytic processing is started. Electrolyte enters the first closed cavity from the water inlet of the water inlet pipe 7, flows into the second closed cavity between the transition sleeve 5 and the electrode plate 10 through each second through hole on the transition sleeve 5, and flows into the upper end surface of the part to be electrolyzed (namely, flows into the other part area of the upper end surface of the part and the cavity gap between the electrode plates) through the gap formed by clearance fit between the electrode plate 10 and each plug. The gap between the electrode plate 10 and the upper end surface of the part to be electrolyzed needs to be ensured to be 0.5mm (which can be adjusted according to the actual electrolysis condition), which is the electrolysis reaction distance, and the cavity gap is filled with charged electrolyte. The holes (cavities) of the electrode plate 10 corresponding to the first plug 6, the second plug 8 and the third plug 9 have outer diameters 1mm larger than the outer diameters of the plugs, and ensure that the gaps passing through the electrolyte are 0.5mm. The other parts of the electrode plate 10 are provided with a plurality of first through holes which are basically equidistant and have the diameter of about phi 0.5-0.8mm, and the diameter can be adjusted and designed according to the specific conditions of the parts. During electrolytic processing, electrolytic reaction occurs between the electrode plate 10 and the part through electrolyte, and as the first plug 6, the second plug 8 and the third plug 9 are attached to a part of the area of the upper end face of the part, the part of the surface corresponding to the part to be electrolyzed is not subjected to electrolytic reaction, so that 'protection' is obtained in the electrolytic process, the other exposed surface of the part is flushed by electrolyte with a certain pressure, the electrolytic reaction is removed, and the electrolyte is discharged along with flowing electrolyte through the water outlet hole of the positioning sleeve 3.
The electrolytic machining device for parts, which is related to in the scheme, is not provided with an electrode feeding mechanism, and the cutting function is achieved only through electrolyte with certain pressure and electrolytic reaction. The surface distance between the electrode plate 10 and the final formed part is kept constant, and the surface distance is unchanged, so that the surface with good roughness is formed stably. When electrolysis starts, the surface of the part to be electrolyzed has the appearance of electrolytic corrosion pits with larger roughness, and the like, and the surface of the part to be electrolyzed gradually deepens along with the increase of the electrolysis time, so that the electrolytic corrosion pits gradually become smaller, and the surface flatness is improved. The shape and depth of the protruding part reserved on the final part meet the requirement of the product. Relevant parameters in the electrolysis process are as follows: the time, the current and voltage, the electrolyte concentration, the water pressure and the like can be adjusted and determined according to the material, the hardness and the depth of the convex shape of the processed part.
In summary, the part electrochemical machining apparatus according to the present embodiment is superior to other electrolytic jigs in terms of the part machining method for the complex convex shape plane, specifically:
1. the plane processing of the complex convex shape of the part with the characteristics of difficult processing, high hardness and the like is carried out on the material, the convex plane is isolated by adopting an insulating device matched with the convex plane shape of the part, and the rest surfaces which are not isolated are removed only during electrolysis, so that the convex shape on the plane of the part attached to the blockage is reserved, and the shaping processing of the complex plane shape of the part is realized.
2. The electrode plate 10 is used as a cathode of the part electrolytic machining device, and a gap which is about 0.5mm larger than a blocking unilateral is formed on the electrode plate, the gap can ensure smooth circulation of electrolyte, and a plane convex shape can be uniformly formed during electrolysis; the rest of the electrode plate 10 is also designed with substantially equidistant water passing holes (first vias) of about 0.5-0.8mm in diameter for passing the electrolyte, which flushes onto the part plane during electrolysis, while the electrolytic reaction takes place to remove the surface to be removed.
3. Because of the diffusion effect of the electrolytic reaction, the side surface of the protruding part of the workpiece can still be removed by electrolysis, so the first plug 6, the second plug 8 and the third plug 9 should be about 0.5mm in diameter (which can be adjusted according to the actual electrolysis condition) than the part to be processed needs to be kept in the protruding shape.
4. The electrolytic machining device for the parts is not provided with an electrode feeding mechanism, and the cutting function is achieved only through electrolyte with certain pressure and electrolytic reaction. The distance between the electrode plate 10 and the surface to be finally formed is kept constant, and the surface is unchanged, so that the surface with good roughness can be formed stably. When electrolysis starts, the surface of the part to be electrolyzed has the appearance of electrolytic corrosion pits with larger roughness, and the like, and the surface of the part to be electrolyzed gradually deepens along with the increase of the electrolysis time, so that the electrolytic corrosion pits gradually become smaller, and the surface flatness is improved. The shape and depth of the protruding part reserved on the final part meet the requirement of the product.
In addition, in this embodiment, a deformation design is further performed for the technical scheme of fig. 2, that is, the cathode-anode direction positioning mechanism is cancelled, and the transition sleeve 5 of the cathode mechanism is directly connected with the sheath 2 of the anode mechanism, at this time, the transition sleeve 5 of the cathode mechanism and the sheath 2 of the anode mechanism form the aforementioned closed cavity, and the chips generated by electrolysis enter the closed cavity formed between the cathode mechanism and the anode mechanism along with flowing electrolyte, so that the chips are discharged from the water outlet hole arranged on the transition sleeve 5 of the cathode mechanism or the sheath 2 of the anode mechanism. This arrangement can achieve the same technical effects as in the above embodiment.
