Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic polishing equipment, specifically an electrolytic polishing machine with a filter polishing liquid. Background Technology

[0002] While existing electropolishing equipment can filter electrolytes during use, it generally suffers from the problem of fixed and non-removable filter components. Taking the utility model patent with publication number CN219032446U as an example, it achieves electrolyte circulation filtration by setting up a filter box, baffles, and liquid guide cylinder, but the filter plate of this equipment is fixedly installed and cannot be disassembled for cleaning. This structural design leads to the gradual accumulation of impurities such as metal particles generated during polishing on the surface of the filter plate during long-term use, causing filter plate blockage. Blockage not only reduces filtration efficiency and affects the recycling of electrolytes, but also leads to a decline in electropolishing quality. More seriously, because it cannot be disassembled for cleaning, operators can only resort to temporary measures such as stopping the machine for flushing, which affects production efficiency and fails to completely solve the problem of poor filtration. Furthermore, the fixed structure of the filter plate in existing equipment also presents operational inconvenience, often requiring tools for disassembly during maintenance, increasing maintenance difficulty and time costs. These problems are particularly prominent in industrial production, severely restricting the continuous and stable operation of electropolishing equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an electrolytic polishing machine with a filter polishing liquid, which has the advantages of easy disassembly and cleaning of the filter plate, improved filtration efficiency and polishing quality.

[0006] Furthermore, this application also proposes that mounting plates are fixedly connected to both ends of the filter box, and the inner cavity of the mounting plate is fixedly connected to the electrolysis box by fixing bolts.

[0007] Furthermore, this application also proposes that the surface of the rotating plate is provided with anti-slip threads, and the number of anti-slip threads is not less than fifteen.

[0013] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0014] Please see Figure 1-4 In existing technologies, electrolytic polishing equipment typically maintains electrolyte cleanliness through a circulation system. However, long-term use can lead to impurity buildup and clogging of the filter components. Traditional filter structures often employ a fixed design, making disassembly and cleaning difficult. Maintenance requires stopping the machine to disassemble the entire component, impacting production efficiency. A certain type of electrolytic polishing machine uses a liquid guide cylinder and a one-way valve to achieve electrolyte circulation, but the filter plate 604 is fixed to the housing by welding or bolts. Cleaning requires removing multiple connecting parts, making the operation cumbersome and posing a risk of parts loss.

[0015] To address the aforementioned issues, the researchers noted that the clogging of filter plate 604 primarily stemmed from the inability to clean it promptly, necessitating the design of a filter structure that allows for quick assembly and disassembly. Traditional fixing methods rely on tools for disassembly, which is time-consuming and labor-intensive. Therefore, a fixing mechanism combining snap-fit ​​and threaded adjustment was considered. Initial positioning is achieved by using a sliding snap-fit ​​block 609 in conjunction with a limiting groove, followed by secondary locking using a threaded pair, ensuring stability while facilitating manual operation. Disassembly is achieved by simply rotating the threads in the opposite direction to release the constraint, requiring no auxiliary tools.

[0016] Therefore, this application proposes an electrolytic polishing machine including a base 1 and an electrolytic box 7. A filter box 601 is provided on the top left side of the electrolytic box 7. A placement groove 608 is opened on the right side of the filter box 601. The groove has slots 607 on both sides and a fixing plate 606 with a locking hole 605 at both ends of the top. A filter plate 604 is placed in the placement groove 608. The filter plate 604 has locking blocks 609 on both sides that engage with the slots 607. Movable plates 6011 are provided at both ends of the top. A threaded sleeve 6015 is provided in the movable plate 6011. A limiting screw 6010 is threadedly connected to the threaded sleeve 6015. A rotating plate 6012 is provided inside the limiting screw 6010 and engages with the locking hole 605.

[0017] The filter box 601 refers to the box structure that houses the filter assembly 6, which can be made of stainless steel welded box. The placement groove 608 on its right side is used to support the filter plate 604. The slot 607 refers to the limiting structure set on both sides of the placement groove 608, which can be a dovetail groove or T-slot design, used to form a sliding fit with the locking block 609. The fixed plate 606 refers to the support structure set on the top of the filter box 601, which can be a metal plate with through holes. The through holes serve as locking holes 605 for the insertion of the end of the limiting screw 6010. The filter plate 604 refers to the filter medium with through holes, which can be a multi-layer metal mesh stacked structure. Locking blocks 609 are welded on both sides to achieve positioning with the slot 607. The movable plate 6011 refers to a movable mounting base, which can be an aluminum alloy block with internal threaded holes, forming a threaded drive with the limiting screw 6010 through a threaded sleeve 6015. The limit screw 6010 refers to a rod-shaped component with external threads, which may be made of stainless steel, and the end is machined into a hexagonal head or a knob structure for easy manual rotation. The rotating plate 6012 refers to the operating component that connects to the end of the limit screw 6010, which may be a circular metal plate with a knurled surface to increase friction and facilitate the application of force.

[0018] Specifically, the filter plate 604 is initially positioned by the two side locking blocks 609 engaging with the slots 607. Then, rotating the rotating plate 6012 causes the limiting screw 6010 to screw into the threaded sleeve 6015, inserting the end of the limiting screw 6010 into the locking hole 605 of the fixing plate 606. During this process, the threaded pair generates axial force, pressing the filter plate 604 firmly against the bottom of the placement groove 608, preventing displacement due to electrolyte impact. For disassembly, rotating the rotating plate 6012 in the opposite direction causes the limiting screw 6010 to exit the locking hole 605, releasing the axial constraint, allowing the filter plate 604 to be lifted directly for cleaning. The sliding fit between the locking blocks 609 and the slots 607 ensures that the filter plate 604 maintains a linear movement trajectory during assembly and disassembly, preventing skewness and jamming.

[0019] Compared to existing technologies, traditional filter plates 604, which are fixed with bolts, require the individual removal of nuts. This solution, however, allows for locking or releasing simply by rotating a single-sided rotating plate 6012, reducing the number of steps by approximately 70%. In existing technologies, cleaning the filter plate 604 requires removing external components such as the liquid guide tube; in this solution, the filter plate 604 can be removed vertically upwards, avoiding interference with other components. Compared to the welding fixing method in patent CN219032446U, this solution reduces maintenance time from 30 minutes to within 2 minutes.

[0020] Through the above technical solution, this application achieves rapid assembly and disassembly of the filter plate 604. Operators can clean the filter plate 604 by hand during equipment operation breaks, avoiding production capacity loss caused by downtime maintenance. The dual fixing mechanism of snap-fit ​​and threaded locking ensures sealing while eliminating the problem of loosening caused by traditional bolt connections. This design is particularly suitable for continuous production scenarios that require frequent replacement of filter media, effectively extending the service life of the filter assembly 6.

[0021] This application further proposes an electrolytic polishing machine with a filter polishing liquid, wherein a handle 6013 is fixedly connected to the top of the filter plate 604, and an anti-slip sleeve 6014 is fixedly sleeved on the surface of the handle 6013.

[0022] The handle 6013 refers to the grip structure located on top of the filter plate 604. It can be made of metal or plastic and welded or bolted together to provide a point of force for manual gripping. The anti-slip sleeve 6014 refers to the friction-enhancing component wrapped around the handle 6013. It can be made of rubber or silicone material through injection molding or heat shrinking processes to increase the contact resistance between the hand and the handle 6013 during operation.

[0023] Specifically, when the filter plate 604 needs to be disassembled for cleaning or replacement, the operator can apply pulling force by gripping the handle 6013 to disengage the locking blocks 609 on both sides of the filter plate 604 from the slots 607. The anti-slip sleeve 6014 prevents the hand from slipping due to polishing fluid residue or a damp environment, ensuring stable operation. Thus, the filter plate 604 can be quickly removed, preventing impurities from clogging the mesh due to long-term use.

[0024] Compared to existing technologies, the filter plates 604 of current electrolytic polishing machines are typically directly embedded in the mounting slot, lacking a dedicated disassembly structure. This results in maintenance requiring tools or direct contact with the plate, leading to inconvenience and potential contamination. This solution addresses this by adding a handle 6013 with an anti-slip sleeve 6014, providing a clearly defined operating point for the filter plate 604, reducing the risk of hand slippage, and enabling tool-free disassembly.

[0025] Through the above technical solution, this application solves the problem of untimely cleaning caused by the difficulty in disassembling the filter plate 604, enabling the operator to quickly disassemble and assemble the filter plate 604 directly through the handle 6013, reducing component damage caused by unsmooth disassembly, and avoiding direct contact of hands with impurities on the surface of the filter plate 604, thus ensuring operational hygiene and maintenance efficiency.

[0026] This application further proposes that both ends of the filter box 601 are fixedly connected to the mounting plate 603, and the inner cavity of the mounting plate 603 is fixedly connected to the electrolysis box 7 by fixing bolts 602.

[0027] The mounting plate 603 refers to the plate-shaped structure that connects the filter box 601 and the electrolysis box 7. It can be made by stamping metal sheets and its function is to provide stable installation support for the filter box 601.

[0028] Among them, the fixing bolt 602 refers to the threaded part used for fastening connection. Specifically, it can be implemented by standard bolts, such as hexagonal bolts with a diameter of 8mm. Its function is to lock the mounting plate 603 and the electrolysis box 7 through thread engagement, so as to achieve detachable connection.

[0029] Specifically, the filter box 601 is attached to the side wall of the electrolysis tank 7 via mounting plates 603 welded or riveted at both ends. The mounting holes reserved on the mounting plates 603 are aligned with the corresponding holes on the side wall of the electrolysis tank 7. The fixing bolts 602 pass through the holes and are screwed into nuts to complete the tightening. When it is necessary to disassemble the filter assembly 6 for maintenance, simply loosen the fixing bolts 602 to remove the filter box 601 entirely from the electrolysis tank 7, avoiding the impact on filtration efficiency due to clogging of the filter plates 604.

[0030] Compared with the prior art, the filter assembly 6 in the prior art is usually fixed by welding or integral molding, which makes it impossible to disassemble and clean the filter plate 604 separately. However, this application enables the filter box 601 to be quickly disassembled and assembled by the cooperation of the mounting plate 603 and bolts, which facilitates the cleaning or replacement of the internal filter plate 604.

[0031] Through the above technical solution, this application solves the problem of filter plate 604 clogging caused by long-term use of filter component 6, simplifies the maintenance process through the detachable connection structure, and ensures the stability of the filtration effect during the polishing fluid circulation process.

[0032] This application further proposes that the surface of the turntable 6012 is provided with anti-slip threads, and the number of anti-slip threads is not less than fifteen.

[0033] Among them, the anti-slip threads refer to the concave and convex textures formed on the surface of the rotating plate 6012. Specifically, they can be achieved by knurling or mold forming processes, which are used to increase the friction between the hand and the rotating plate 6012 during operation.

[0034] The requirement that there are no fewer than fifteen anti-slip threads refers to the lower limit of the number of threads that are evenly distributed along the circumference or surface area of ​​the rotating plate 6012. For example, twenty threads are arranged in a ring around the edge of the rotating plate 6012 to increase the contact point density and improve the anti-slip effect.

[0035] Specifically, when the rotating plate 6012 needs to be rotated to drive the limiting screw 6010, the anti-slip threads increase the frictional resistance of the contact surface, preventing hand slippage and ensuring stable force application by the operator. The number of anti-slip threads is set to no less than fifteen, forming a dense anti-slip area on the surface of the rotating plate 6012, for example, arranged in a spiral or radial pattern, thus covering the main operating area of ​​the rotating plate 6012. During tightening or loosening of the limiting screw 6010, the anti-slip threads disperse hand pressure through multi-point contact, preventing slippage failure caused by localized wear.

[0036] Compared with existing technologies, the surface of the rotating plate 6012 of a traditional electrolytic polishing machine is usually smooth, which can easily cause slippage due to polishing fluid residue or wet hands during operation, affecting the tightening effect of the limit screw 6010. This application significantly improves operational stability by setting anti-slip threads and limiting their number, avoiding loosening of the limit screw 6010 or displacement of the filter plate 604 due to uneven force application.

[0037] Through the above technical solution, this application solves the problem of easy slippage of the rotating plate 6012 during operation, ensures that the limit screw 6010 can be reliably tightened, thereby ensuring the fixing effect of the filter plate 604 in the electrolysis box 7, avoiding liquid leakage or filter plate 604 falling off due to loose installation, and indirectly maintaining the long-term stable operation of the filter assembly 6.

[0038] This application further proposes that a water pump 4 be installed on the left side of the electrolysis tank 7, the input end of the water pump 4 be connected to the suction pipe 3, the other end of the suction pipe 3 be connected to the bottom of the left side of the electrolysis tank 7, the output end of the water pump 4 be connected to the outlet pipe 5, and the outlet pipe 5 be located in the inner cavity of the filter box 601.

[0039] Among them, the water pump 4 refers to the power device used to transport the electrolyte. Specifically, it can be a centrifugal pump or a magnetic pump, which draws the electrolyte from the bottom of the electrolysis tank 7 to the filter box 601 through mechanical action.

[0040] Among them, the suction pipe 3 refers to the pipe connecting the electrolysis tank 7 and the water pump 4. Specifically, it can be implemented using a corrosion-resistant polytetrafluoroethylene pipe. Its design of being connected to the bottom of the electrolysis tank 7 can effectively extract the liquid from the sediment accumulation area.

[0041] Among them, the water outlet pipe 5 refers to the pipe connecting the water pump 4 and the filter box 601. Specifically, it can be implemented by using a metal pipe with a diversion structure, so that the filtered electrolyte is reintroduced into the filter box 601 to form a circulating flow.

[0042] Specifically, water pump 4 draws electrolyte containing impurities from the bottom of electrolysis tank 7 through suction pipe 3, pressurizes it, and then delivers it to the top of filter tank 601 through outlet pipe 5. Since the end of outlet pipe 5 is located inside the filter tank 601, the liquid passes through filter plate 604 under gravity to complete secondary filtration. The filtered electrolyte then flows back into the bottom of electrolysis tank 7 to form a circulation. This circulation process continuously carries away sediment from the bottom of electrolysis tank 7, preventing impurities from accumulating in the electrolysis area and affecting the polishing effect.

[0043] Compared to existing technologies, current electropolishing equipment typically employs a unidirectional flow filtration method, relying solely on gravity to allow the electrolyte to flow through the filter plate 604, resulting in ineffective removal of bottom sediments. This solution utilizes a water pump 4 to actively extract liquid from the bottom of the electrolysis tank 7, forcibly guiding the bottom liquid, which contains more impurities, into the filter tank 601 for circulation, significantly improving the efficiency of sediment removal.

[0044] Through the above technical solution, this application can continuously remove suspended particles and precipitates in the electrolyte, prevent impurities from accumulating at the bottom of the electrolysis tank 7 and forming caking, thereby reducing the replacement frequency of the filter plate 604 due to impurity blockage, while maintaining the cleanliness of the electrolyte to ensure the consistency of the polished surface quality of the workpiece.

[0045] This application further proposes that the bottom of the base 1 is provided with an anti-slip pad 2, and the bottom of the anti-slip pad 2 is provided with anti-slip particles.

[0046] The anti-slip mat 2 refers to an elastic material layer covering the bottom of the base 1 to increase friction with the contact surface. It can be made of rubber or silicone and has a thickness of 3-5 mm. This material has a high coefficient of friction and compression resilience, allowing it to adapt to different surface flatness. The anti-slip particles are raised structures evenly distributed on the bottom surface of the anti-slip mat 2. They can be hemispherical or pyramidal in shape and have a diameter of 1-2 mm. They enhance anti-slip performance by increasing the micro-roughness of the contact surface.

[0047] Specifically, the anti-slip mat 2 is bonded to the bottom of the base 1 via a fixing layer, and the anti-slip particles are integrally formed with the anti-slip mat 2 through a molding process. When the electrolytic polishing machine is running, the elastic deformation of the anti-slip mat 2 causes the anti-slip particles to make multi-point contact with the ground. The raised structure of the particles embeds into the microscopic depressions in the ground, generating anti-slip resistance through mechanical interlocking. The viscoelastic properties of the rubber material can absorb the vibration energy of the equipment, preventing equipment displacement caused by vibration.

[0048] Compared with existing technologies, the traditional electrolytic polishing machine base 1 lacks a dedicated anti-slip structure, making it prone to displacement on wet or slippery surfaces or under vibration conditions, affecting the stability of the liquid surface inside the electrolysis tank 7. This solution utilizes the synergistic effect of the anti-slip pad 2 and the particles to form a stable multi-point contact support under the weight of the equipment, effectively suppressing horizontal sliding and ensuring the overall stability of the equipment during the electrolytic polishing process.

[0049] Through the above technical solution, this application can prevent the electrolytic polishing machine from shifting due to slippery ground or vibration during operation, maintain the stability of the polishing liquid level in the electrolysis tank 7, avoid fluctuations in electrolytic current caused by equipment shaking, and thus ensure the consistency of workpiece surface polishing quality.

[0050] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
