Description

Technical Field

[0001] The utility model relates to the field of electrolytic polishing equipment, and more particularly to a lifting electrolytic device. Background Art

[0002] Electropolishing is a method for finishing the surface of a metal workpiece by passing an electrolyte through a circuit. As the electrolysis proceeds, a highly viscous liquid film forms on the workpiece's surface. The film's thickness is uneven across the workpiece's uneven surface, with a thin film on raised areas and a thicker film on the rest of the surface. Consequently, the resistance varies across the anode surface. The raised areas of the metal workpiece have lower resistance and higher current density, causing them to dissolve faster than the concave areas. As a result, the rough surface of the workpiece becomes smooth and shiny, achieving a polished finish.

[0004] In the electrolytic polishing device described in the aforementioned prior art, a cup-shaped workpiece is formed and electrolyte is injected into its interior in an inverted manner for electrolytic polishing. In order to seal the cup mouth of the inverted state of the workpiece, a seal is required. The seal is usually made of elastic materials such as silicone or rubber.

[0012] The lifting seat includes a mounting plate and a support plate. The mounting plate is vertically mounted on the upper surface of the supporting plate. The support plate is a right-angled triangular plate body and the two right-angled sides of the support plate are respectively in contact with the side wall of the support plate and the upper surface of the supporting plate.

[0027] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.

[0028] Ginseng Figures 1 to 8This is a specific embodiment of a lifting electrolysis device disclosed by the utility model. The beneficial effect of the utility model is that after the workpiece 3 is placed on the first electrode 11 of the supporting plate 1 with the opening 32 facing upward, the lifting frame 41 of the lifting device 4 drives the second electrode 2 to extend into the opening 32 of the workpiece 3. Since the second electrode 2 has a liquid inlet 21 with a larger diameter than the liquid outlet 22, and the liquid inlet 21 and the liquid outlet 22 are connected to each other, electrolyte is injected into the liquid inlet 21 of the second electrode 2 so that the electrolyte fills the interior of the workpiece 3 from the liquid outlet 22 and then stops. The second electrode 2 maintains the state in which the liquid outlet 22 extends into the opening 32 of the workpiece 3, and power is applied to the first electrode 11 and the second electrode 2 to electrolytically polish the inner surface of the workpiece 3 with the electrolyte until the inner surface of the workpiece 3 reaches a smooth state after a sufficient electrolytic polishing time. The lifting frame 41 then drives the second electrode 2 to rise so that the liquid outlet 22 is moved out of the opening 32 of the workpiece 3. Compared with the prior art, the workpiece 3 is placed on the support plate 1 with the opening 32 facing upward, and the electrolyte is injected into the workpiece 3 and the workpiece 3 is used as an electrode for electrolytic polishing by raising and lowering the second electrode 2. First, the forward placement of the workpiece 3 effectively avoids the problem of electrolyte leakage, omits the seals that may have poor sealing in the prior art, and further avoids the problem of poor electrolytic polishing of the inner surface of the workpiece due to gas entering the workpiece when the electrolyte is injected into the workpiece 3.

[0029] Ginseng Figures 1 to 8 As shown, in this embodiment, the lifting electrolytic polishing device includes a first electrode 11, a second electrode 2, and a support plate 1. The first electrode 1 is formed on the upper surface of the support plate 1. The bottom 31 of the workpiece 3 contacts the first electrode 11 and forms a passage. The second electrode 2 is assembled to the upper surface of the support plate 1 by a lifting device 4. The lifting device 4 includes a lifting frame 41 and a lifting seat 42. The lifting seat 42 is fixed to the upper surface of the support plate 1. The second electrode 2 has a liquid inlet 21 and a liquid outlet 22. The diameter of the liquid inlet 21 is larger than that of the liquid outlet 22, and the liquid inlet 21 and the liquid outlet 22 are interconnected. The lifting frame 41 drives the second electrode 2 to slide along the height direction of the lifting seat 42 so that the liquid outlet 22 of the second electrode 2 extends into the opening 32 of the workpiece 3. It should be noted that the first electrode 11 is a conductive metal plate. The workpiece 3 is placed in a positive direction so that its bottom 31 contacts the first electrode 11 to achieve the purpose of forming a passage.

[0030] When electrolytic polishing is required on the inner surface of the workpiece 3, the workpiece 3 is placed on the upper surface of the support plate 1 with the opening 32 facing upward. The bottom 31 of the workpiece 3 is in contact with the first electrode 11 formed on the surface of the support plate 1. At this time, the lifting frame 41 is located at the highest point of the lifting base 42, and the liquid outlet 22 of the second electrode 2 is located above the opening 32 of the workpiece 3. After the workpiece 3 is placed on the surface of the first electrode 11, the lifting frame 41 drives the second electrode 2 downward along the lifting base 42 until the liquid outlet 22 of the second electrode 2 is inserted into the opening 32 of the workpiece 3. Electrolyte is injected into the liquid inlet 21 of the second electrode 2 through a metering valve (not shown) or other liquid-injecting device. The electrolyte is then filled into the interior of the workpiece 3 through the liquid outlet 22, and injection is stopped. The second electrode 2 is maintained in a state where the liquid outlet 22 is inserted into the opening 32 of the workpiece 3. Power is then supplied to the first electrode 11 and the second electrode 2, allowing the electrolyte to electrolytically polish the inner wall of the workpiece 3. After the electrolytic polishing of the inner wall of the workpiece 3 is completed, the lifting frame 41 drives the second electrode 2 to slide upward along the lifting base 42 to the liquid outlet 22 and be lifted out of the opening 32 of the workpiece 3. Compared to the prior art method of injecting electrolyte into the workpiece 3 for electrolytic polishing in an inverted manner, this method achieves the purpose of electrolytic polishing by injecting the correct amount of electrolyte into the workpiece 3 without the need for a seal, thereby effectively preventing leakage of electrolyte from the workpiece 3 and the ingress of external air into the workpiece 3, and effectively ensuring the electrolytic polishing effect on the inner surface of the workpiece 3.

[0031] Ginseng Figure 5 and Figure 6 As shown, the lifting frame 41 includes a lifting plate 413 and a frame body 414, the lifting plate 413 slides with the lifting seat 42, the frame body 414 is vertically fixed to the lifting plate 413 away from the lifting seat 42, the second electrode 2 is vertically passed through and fixed in the frame body 414, and the force-bearing member 411 is assembled on the side of the lifting plate 413 away from the second electrode 2; the lifting seat 42 includes a mounting plate 421 and a support plate 422, the mounting plate 421 is vertically assembled on the upper surface of the supporting plate 1, the support plate 422 is a right-angled triangle plate body and the two right-angled sides of the support plate 422 are respectively fitted with the side wall of the support plate 422 and the upper surface of the supporting plate 1, a guide rail 423 is provided in the height direction on the side of the mounting plate 421 away from the support plate 422, the lifting plate 413 slides with the mounting plate 421 through the guide block 4121 and the guide rail, and the frame body 414 is vertically assembled on the side of the lifting plate 413 away from the mounting plate 421. The lifting plate 413 is located below the force-bearing member 411 and fixedly connected to the positioning member 412 . When the liquid outlet 22 of the second electrode 2 extends into the opening 32 of the workpiece 3 , the positioning member 412 abuts against the upper surface of the guide rail 423 .

[0032] Ginseng Figures 1 to 8As shown, the electrolytic polishing device also includes: a driving mechanism 6 and a frame 5, the driving mechanism 6 includes a driving cylinder 61 and a flip member 63, the driving end of the driving cylinder 61 is arranged downwardly perpendicular to the plane where the supporting plate 1 is located and is connected to the flip member 63 through a lifting plate 62, and a force-bearing member 411 is provided on the side of the lifting frame 41 away from the second electrode 2, the flip member 63 abuts against the lower surface of the force-bearing member 411 to drive the lifting frame 41 and the second electrode 2 to rise in a direction away from the first electrode 11, and the driving end of the driving cylinder 61 drives the flip member 63 to move downward until it is separated from the force-bearing member 411 so that the liquid outlet 22 of the second electrode 2 extends into the opening 32 of the workpiece 3. Specifically, the top wall of the frame 1 is vertically fixed to the support 64 via the base plate 641. The lifting plate 62 is fixed to the slide rail 621 in the height direction. The side wall of the support 64 in the height direction is connected to the slider 6411. The support plate 642 is disposed on the side of the support 64 away from the slider 6411. The support plate 642 is a right-angled triangular plate, and its two right-angled sides are respectively attached to and fixed to the support 64 and the base plate 641. The slider 6411 and the slide rail 621 are interlocked and slidably engaged with each other. The driving end of the driving cylinder 61 is connected to the lifting plate 62 via the connecting member 611. The driving end of the driving cylinder 61 drives the lifting plate 62 to slide relative to the support 64 in the height direction via the slide rail 621 and the slider 6411 through the connecting member 611, so that the flip member 63 drives the force-bearing member 411 to rise or to disengage from the force-bearing member 411.

[0033] It should be noted that Figure 2 、 Figure 4 as well as Figure 7 As shown, the turning portion 63 is configured as a plate-like member with a certain length and thickness, and a wedge-shaped surface 632 is formed between the bottom surface of the turning portion 63 and the connection portion thereof away from the connecting shaft 631. The workpiece 3 is placed on the first electrode 11, and the driving end of the driving cylinder 61 is extended; when the liquid outlet 22 of the first electrode 2 is located above the opening 32 of the workpiece 3 (as shown in FIG. Figure 1 and Figure 2 As shown), at this time, the driving end of the driving cylinder 61 is in a fully extended state, and the lifting plate 62 connected to the driving end of the driving cylinder 61 through the connecting piece 611 drives the flip member 63 to move to the lowest point. At this time, the flip member 63 and the force-bearing member 411 are in a mutually separated state. At this time, the lifting frame 41 is subjected to the action of gravity as a whole, and the guide block 4121 assembled on the lifting plate 413 slides downward along the guide rail 423 of the mounting plate 421 until the positioning piece 412 assembled on the lifting plate 413 abuts against the upper edge of the guide rail 423. In addition, the flip member 63 loses the gravity applied by the force-bearing member 411 and flips upward with the connecting shaft 631 as the axis. Figure 4As shown in the state. Since the flip member 63 is completely separated from the force-bearing member 411, it can be seen that there is no contact between the driving mechanism 6 and the lifting device 4 at this time, and the electrolyte is injected into the liquid inlet 21 of the first electrode 2 until the interior of the workpiece 3 is filled. In this embodiment, the connecting shaft 631 is selected as a flip pin. When the flip member 63 loses the downward pulling force applied by the force-bearing member 411, the connecting shaft 631 drives the force-bearing member 411 to flip to Figure 4 The position shown in the figure is held until the next driving cylinder 61 drives the flip member 63 to rise to contact the force-bearing member 411, and the flip member 63 rotates in the opposite direction with the connecting shaft 631 as the axis. Figure 2 Status shown.

[0034] Ginseng Figure 5 and Figure 6 As shown, the second electrode 2 includes an electrolytic rod 23 and a liquid guide 24 connected to the top of the electrolytic rod 23. The liquid inlet 21 is formed at the top of the liquid guide 24. The liquid guide 24241 defines a liquid guide cavity. The cross-section of the liquid guide cavity 241 is formed in an inverted cone. The electrolytic rod 23 of the second electrode 2 is vertically fixed to the frame 414 via an assembly 415. The frame 414 has an installation opening (not marked) for the assembly part 415 to pass through. The assembly part 415 includes: an electrode fixing part 4151, an insulating sleeve 4152, a locking nut 4153 and a clamping part 4154. The electrolytic rod 23 constituting the first electrode 2 passes through the electrode fixing part 4151 in the axial direction. The insulating sleeve 4152 is assembled on the outside of the electrode fixing part 4151. The protrusion (not marked) of the electrode fixing part 4151 is in contact with the bottom end of the insulating sleeve 4152. The top end of the insulating sleeve 4152 has a protrusion (not marked). The outer wall of the insulating sleeve 4152 is in contact with the inner wall of the installation opening (not marked). The lower surface of the protrusion (not marked) of the insulating sleeve 4152 is in contact with the upper surface of the frame 414. The locking nut 4153 is assembled on the top end of the electrode fixing part 4151 and abuts against the upper surface of the insulating sleeve 4152. The clamping part 4154 is as shown in FIG. Figure 5 and Figure 6 As shown, it is mounted on the bottom end of the electrode fixing member 4151, thereby achieving the purpose of stably mounting the electrolysis rod 23 on the frame 414. Furthermore, the electrode fixing member 4151 also has a conductive function. A power source (not shown) is electrically connected to the electrode fixing member 4151 to achieve the purpose of supplying power to the second electrode 2 as a whole.

[0035] It should be noted that in this embodiment, the liquid guide 24 and the electroplating rod 23 are both made of conductive metal. The liquid guide 24 is formed in a funnel shape with a larger top and a smaller bottom. After the electroplating liquid is injected into the liquid guide 24 from the liquid inlet 21, it is guided into the electroplating rod 23 by the liquid guide cavity 241 formed in the device, and is injected into the workpiece through the liquid outlet 22 under the guidance of the electroplating rod 23. The electrolyte is injected into the liquid inlet 21 through a metering pump (not shown) or any other device capable of liquid injection. Since the liquid inlet 21 has a larger diameter than the liquid outlet 22, the electrolyte can be injected to smoothly guide the electrolyte into the workpiece 3. It should be noted that the metering pump or other liquid injection device is arranged directly below the drive device 6 (not shown) to achieve the purpose of injecting the electrolyte into the workpiece 3 located on the first electrode 11 through the second electrode 2.

It should be noted that in this embodiment, the positioning seat 16 is provided with two workpieces whose bottoms 31 are in contact with the first electrode 11. The frame 414 is provided with two or more second electrodes 2 in parallel. It should be noted that since the positioning seat 16 in this embodiment places two workpieces 3 in total, two second electrodes 2 are arranged in parallel in the frame 414, the number of which is the same as the number of the workpieces 3, and the liquid outlets 22 of the two second electrodes 2 extend into the openings 32 of the two workpieces 3 at the same time. It should be noted that in this embodiment, the positioning seat 16 is selected to be a cup-shaped flower basket made of an elastic material (such as plastic, etc.), and the two workpieces 3 are placed into the positioning seat 16 from top to bottom at the same time so that their bottoms 31 are simultaneously in contact with the first electrode 31, and the liquid outlets 22 of the two second electrodes 2 are simultaneously extended into the openings 32 of the two workpieces 3, so as to achieve the purpose of electrolytic polishing the inner surfaces of the two workpieces 3 at the same time.
