Description

Technical Field

[0001] This invention relates to the field of metal parts processing technology, specifically to a micro-arc chamfering device for the edges and corners of equipment-type metal parts. Background Technology

[0002] Chamfering the edges and corners of metal parts is a key process to improve their assembly compatibility and safety of use. It can effectively avoid problems such as stress concentration and scratches caused by sharp edges and corners during use. Micro-arc chamfering has become the mainstream process for processing the edges and corners of metal parts because it combines chamfering and surface ceramic strengthening effects.

[0003] Existing micro-arc chamfering devices still have many shortcomings in industrial mass production. Their electrolyte filtration is mostly a single-path structure, and the electrolyte circulation needs to be cut off when cleaning and maintaining the filter components, which leads to process interruption and significantly reduces production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a micro-arc chamfering device for the edges and corners of metal accessories for equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a micro-arc chamfering device for metal parts of equipment, comprising an electrolytic cell and a valve, wherein the electrolytic cell is provided with an auxiliary component for limiting the position, and the auxiliary component includes a connecting rod, an upper clamping plate, a polytetrafluoroethylene (PTFE) positioning pin, and a lower clamping plate. The lower clamping plate is installed at the bottom of the connecting rod, and the upper clamping plate is provided above the lower clamping plate. The upper clamping plate is provided with a PTFE positioning pin inside. A pipe body is installed at the bottom of the electrolytic cell, and the valve is located on one side of the pipe body. A filter pipe is fixedly installed at the bottom of the pipe body through a flange, and a filter disc is provided inside the filter pipe.

[0006] Furthermore, the filter discs are provided in two sets, and an internal column is installed in the middle of the two sets of filter discs.

[0007] Furthermore, the filter tube has an internal base plate at its inner bottom, and the internal base plate has a circular structure.

[0008] Furthermore, the filter tube is fixedly mounted with a bottom frame via a flange, and the bottom frame has a hollow internal structure.

[0009] Furthermore, a conduit is provided on one side of the bottom frame, and a fluoroplastic self-priming pump is installed at the end of the conduit.

[0010] Furthermore, a water storage frame is provided on the outside of the electrolytic cell, and a top cover is snapped onto the top of the water storage frame. Water pipes are installed on both sides of the water storage frame, and a water pump is provided at the end of a set of water pipes.

[0011] Furthermore, the auxiliary assembly also includes a top rod and an end cap, with the top rod slidably mounted on the top of the connecting rod and the end cap threadedly mounted on the end of the top rod.

[0012] Furthermore, an auxiliary loading and unloading drive assembly is installed at the end of the top rod away from the end cover, and the drive assembly includes a base plate, a hydraulic rod and a top plate. The hydraulic rod is installed on the outer surface of the base plate, and the top plate is installed at the output end of the hydraulic rod.

[0013] This invention provides a micro-arc chamfering device for the edges and corners of metal parts used in equipment, which has the following advantages: 1. This invention achieves uninterrupted electrolyte filtration by arranging three sets of filter tubes in parallel and equipping each corresponding tube with an independent valve. This effectively improves the continuity and production efficiency of the micro-arc chamfering process. Under normal operating conditions, the three sets of filter tubes simultaneously perform double-layer filtration, significantly improving the electrolyte filtration efficiency and cleanliness. When a single set of filter tubes needs cleaning, only the corresponding valve needs to be closed to complete the disassembly and maintenance, while the other two sets continue filtration, avoiding process interruptions caused by filtration pauses. At the same time, the closed-loop circulation system continuously supplies clean electrolyte to the electrolytic cell, effectively preventing waste residue from clogging the gaps of the auxiliary component clamps and adhering to the edges of metal parts. This avoids problems such as uneven discharge and rough chamfered surfaces from the source, ensuring the stability of electrolyte circulation and the uniformity of micro-arc discharge.

[0014] 2. This invention achieves automated and precise clamping and loading / unloading of metal parts through the linkage design of the drive component and the auxiliary component. The hydraulic rod drives the auxiliary component to rise and fall, and with the precise limiting of the PTFE positioning pin, it effectively prevents the workpiece from shifting during the micro-arc chamfering process, ensuring the consistency of the chamfering dimensions of each edge and corner of the part, and meeting the positioning accuracy requirements of batch processing of metal parts for equipment. At the same time, the cooling system composed of the water storage frame and the water pump provides constant temperature protection for the electrolytic cell throughout the process, and removes the heat generated by the micro-arc discharge in time, maintaining the stability of the electrolyte temperature.

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figures 1-5As shown, a micro-arc chamfering device for metal fittings of an equipment category includes a water storage frame 1, a top cover 2, an electrolytic cell 3, a bottom frame 4, a water pipe 5, a water pump 6, a conduit 7, a fluoroplastic self-priming pump 8, a pipe body 9, a flange 10, a filter pipe 11, a drive assembly 12, a base plate 1201, a hydraulic rod 1202, a top plate 1203, a valve 13, a filter disc 14, an internal base plate 15, an auxiliary assembly 16, a top rod 1601, an end cap 1602, a connecting rod 1603, an upper clamping plate 1604, a polytetrafluoroethylene positioning pin 1605, a lower clamping plate 1606, and an internal column 17. The electrolytic cell 3 is internally equipped with a limiting device. The auxiliary component 16 includes a connecting rod 1603, an upper clamping plate 1604, a polytetrafluoroethylene (PTFE) positioning pin 1605, and a lower clamping plate 1606. The auxiliary component 16 also includes a push rod 1601 and an end cap 1602. The push rod 1601 is slidably mounted on the top of the connecting rod 1603. An auxiliary loading / unloading drive component 12 is mounted on the end of the push rod 1601 away from the end cap 1602. The drive component 12 includes a base plate 1201, a hydraulic rod 1202, and a top plate 1203. The hydraulic rod 1202 is mounted on the outer surface of the base plate 1201, and the top plate 1203 is mounted on the output end of the hydraulic rod 1202. 3. The hydraulic rod 1202 of the drive assembly 12 extends, driving the top plate 1203 and auxiliary assembly 16 to rise and fall, removing the chamfered workpiece from the electrolyte in the electrolytic cell 3. Workers can directly remove the processed metal parts from between the upper clamping plate 1604 and the lower clamping plate 1606 of the auxiliary assembly 16. An end cap 1602 is threaded onto the end of the top rod 1601. The lower clamping plate 1606 is installed at the bottom of the connecting rod 1603, and an upper clamping plate 1604 is positioned above the lower clamping plate 1606. A polytetrafluoroethylene (PTFE) positioning pin 1605 is installed inside the upper clamping plate 1604. The bottom of the electrolytic cell 3 is equipped with... The tube body 9 and valve 13 are located on one side of the tube body 9. The bottom of the tube body 9 is fixedly installed with a filter tube 11 via flange 10. The filter tube 11 is fixedly installed with a bottom frame 4 via flange 10. The bottom frame 4 has a hollow internal structure. A conduit 7 is provided on one side of the bottom frame 4. A fluoroplastic self-priming pump 8 is installed at the end of the conduit 7. The three sets of filter tubes 11 ensure uninterrupted filtration and improve process continuity. The bottom of the electrolytic cell 3 corresponds to the three sets of filter tubes 11. Three independent tube bodies 9 are set. Each tube body 9 is equipped with a valve 13 to independently control the electrolyte flow of the corresponding tube body 9 and filter tube 11.Each tube 9 is rigidly connected to its corresponding filter tube 11 via a flange 10. The three sets of filter tubes 11 are arranged in parallel and are all connected to the hollow bottom frame 4 via flanges 10, ensuring that the filtered electrolyte can flow into the bottom frame 4 uniformly. The internal structure of each set of filter tubes 11 is consistent. The inner bottom ring-shaped built-in base plate 15 provides bottom support for the two sets of filter discs 14. The built-in column 17 passes through the middle of the two sets of filter discs 14 to axially limit the filter discs 14 and prevent the filter discs 14 from shifting due to electrolyte impact. The two sets of filter discs 14 perform double-layer filtration of waste residue in the electrolyte, effectively removing impurities such as metal oxides and precipitates generated by the micro-arc reaction, improving the electrolyte filtration accuracy. During normal operation, the three sets of filters... When pipe 11 is opened, the corresponding valves 13 are also opened. The electrolyte flows into the three sets of filter pipes 11 through the three pipes 9, and after double-layer filtration, it flows into the bottom frame 4. When it is necessary to clean a certain set of filter pipes 11, simply close the valve 13 corresponding to that set of filter pipes 11 to cut off the electrolyte passage for that set. Then, it can be disassembled and cleaned, such as replacing the filter disc 14 and removing waste residue. At this time, the valves 13 of the other two sets of filter pipes 11 remain open, and the electrolyte filtration continues, ensuring that the closed-loop circulation of the electrolyte is uninterrupted. This avoids affecting the progress and processing quality of the micro-arc chamfering process due to filtration interruption. The bottom frame 4 provides temporary storage space for the filtered clean electrolyte. The fluoroplastic self-priming pump 8 draws the clean electrolyte from the bottom frame 4 through the conduit 7. The electrolyte is then returned to the electrolytic cell 3 to continuously supply clean electrolyte for the micro-arc chamfering process. This prevents waste residue from clogging the gaps in the clamping plates of the auxiliary component 16, ensuring the flow of electrolyte around the edges of the metal parts. An internal base plate 15 with a circular structure is installed at the bottom inner side of the filter tube 11. Two sets of filter plates 14 are installed inside the filter tube 11, with an internal column 17 installed in the middle of each set. The drive component 12 is the core of the device's loading and unloading power. Its base plate 1201 serves as the mounting foundation, providing fixed support for the hydraulic rod 1202. When the hydraulic rod 1202 extends and retracts, it drives the top plate 1203 to rise and fall synchronously. The top plate 1203 and the top rod of the auxiliary component 16... A rigid connection 1601 enables the vertical lifting of the entire auxiliary component 16, facilitating automated workpiece loading and unloading. The auxiliary component 16 is the core component for workpiece clamping and positioning. The end cap 1602, through a threaded connection, secures the push rod 1601 and connecting rod 1603. Connecting rod 1603 provides connection support between the upper clamping plate 1604 and the lower clamping plate 1606, forming a workpiece clamping frame. A PTFE positioning pin 1605 passes through the upper clamping plate 1604, precisely limiting the positioning of metal parts placed between the upper and lower clamping plates 1604 and 1606, preventing workpiece displacement during micro-arc chamfering, ensuring consistent chamfer dimensions across all edges of the parts, and meeting the positioning accuracy requirements for batch processing.

[0019] like Figure 1 and Figure 2 As shown, an external water storage frame 1 is provided for the electrolytic cell 3, and a top cover 2 is snapped onto the top of the water storage frame 1. Water pipes 5 are installed on both sides of the water storage frame 1, and a water pump 6 is installed at the end of one set of water pipes 5. The electrolytic cell 3 is the core process cavity for micro-arc chamfering, and contains the electrolyte required for micro-arc discharge, ensuring that the clamped metal parts can be completely immersed in the electrolyte, realizing immersion micro-arc chamfering. The water storage frame 1 is fitted outside the electrolytic cell 3 and filled with cooling medium to provide full-process cooling protection for the electrolytic cell 3. The top cover 2 is snapped onto the top of the water storage frame 1 to effectively prevent the cooling medium from evaporating and escaping. The water pipes 5 on both sides of the water storage frame 1 and the water pump 6 form a circulation loop for the cooling medium. The water pump 6 drives the cooling medium to flow continuously between the two sets of water pipes 5 and the water storage frame 1, which can promptly remove the heat generated by the micro-arc discharge in the electrolytic cell 3, maintain the temperature stability of the electrolyte in the electrolytic cell 3, and avoid problems such as uneven discharge and rough surface of the chamfered parts caused by excessive electrolyte temperature.

[0020] In summary, the micro-arc chamfering device for the edges and corners of this type of equipment's metal fittings is first based on... Figures 1-5In the structure shown, during use, the drive assembly 12 is the core of the device's loading and unloading power. Its base plate 1201 serves as the mounting foundation, providing fixed support for the hydraulic rod 1202. When the hydraulic rod 1202 extends and retracts, it drives the top plate 1203 to rise and fall synchronously. The top plate 1203 is rigidly connected to the top rod 1601 of the auxiliary assembly 16, thereby realizing the vertical lifting of the entire auxiliary assembly 16 and completing the automated loading and unloading of workpieces. The auxiliary assembly 16 is the core component for workpiece clamping and positioning. The end cap 1602 achieves the tight linkage between the top rod 1601 and the connecting rod 1603 through a threaded connection. The connecting rod 1603 provides connection support for the upper clamping plate 1604 and the lower clamping plate 1606, forming a workpiece clamping frame. The polytetrafluoroethylene positioning pin 1605 is inserted. Inside the upper clamping plate 1604, the metal parts of the equipment placed between the upper clamping plate 1604 and the lower clamping plate 1606 are precisely positioned to prevent the workpiece from shifting during the micro-arc chamfering process, ensuring that the chamfering dimensions of each corner of the part are consistent and meeting the positioning accuracy requirements of batch processing. The electrolytic cell 3 is the core process cavity for micro-arc chamfering, containing the electrolyte required for micro-arc discharge, ensuring that the clamped metal parts can be completely immersed in the electrolyte, realizing immersion micro-arc chamfering. The water storage frame 1 is fitted outside the electrolytic cell 3 and filled with cooling medium to provide full-process cooling protection for the electrolytic cell 3. The top cover 2 is snapped onto the top of the water storage frame 1 to effectively prevent the cooling medium from evaporating and leaking. The water pipes 5 on both sides of the water storage frame 1 and the water pump 6 form the cooling medium. In the circulation loop, the water pump 6 drives the cooling medium to continuously flow between the two sets of water pipes 5 and the water storage frame 1, promptly removing the heat generated by the micro-arc discharge in the electrolytic cell 3, maintaining the stable temperature of the electrolyte in the electrolytic cell 3, and avoiding problems such as uneven discharge and rough surface of the chamfered parts caused by excessively high electrolyte temperature. During the micro-arc chamfering process, the electrolyte will generate waste residue due to the discharge reaction of the metal parts. To ensure the cleanliness of the electrolyte and the stability of the discharge, the device forms a closed-loop filtration circulation system for the electrolyte through the linkage of multiple components, and the three sets of filter pipes 11 ensure uninterrupted filtration process and improve process continuity: the bottom of the electrolytic cell 3 corresponds to the three sets of filter pipes 11, with three independent pipe bodies 9, each pipe body 9 equipped with a corresponding valve 13 for independent control. Electrolyte flow in and out of the tube body 9 and filter tube 11; each tube body 9 is rigidly connected to the corresponding filter tube 11 through a flange 10. The three sets of filter tubes 11 are distributed in parallel and are all connected to the hollow bottom frame 4 through flanges 10 to ensure that the filtered electrolyte can flow into the bottom frame 4. The internal structure of each set of filter tubes 11 is the same. The inner bottom ring-shaped built-in base plate 15 provides bottom support for the two sets of filter discs 14. The built-in column 17 passes through the middle of the two sets of filter discs 14 to axially limit the filter discs 14 and prevent the filter discs 14 from shifting due to electrolyte impact. The two sets of filter discs 14 perform double-layer filtration of waste residue in the electrolyte, effectively removing impurities such as metal oxides and precipitates generated by the micro-arc reaction and improving the electrolyte filtration accuracy.

[0021] During normal operation, the three sets of filter tubes 11 are opened simultaneously (corresponding valves 13 are all open). The electrolyte flows into the three sets of filter tubes 11 through the three tubes 9 respectively. After double-layer filtration, it flows into the bottom frame 4. When a set of filter tubes 11 needs to be cleaned, only the valve 13 corresponding to that set of filter tubes 11 needs to be closed to cut off the electrolyte passage of that set. Then it can be disassembled and cleaned (such as replacing the filter disc 14 and removing waste residue). At this time, the valves 13 of the other two sets of filter tubes 11 are still kept open to continue the electrolyte filtration work, ensuring that the closed-loop circulation of electrolyte is not interrupted. This avoids affecting the progress and processing quality of the micro-arc chamfering process due to filtration pause. The bottom frame 4 provides a temporary storage space for the filtered clean electrolyte. The fluoroplastic self-priming pump 8 draws clean electrolyte from the bottom frame 4 through the conduit 7 and sends it back to the electrolytic tank 3 to continuously supply clean electrolyte for the micro-arc chamfering process. At the same time, it avoids waste residue clogging the gap of the clamping plate of the auxiliary component 16 and ensures the flow of electrolyte at the edges and corners of the metal parts. When the auxiliary component 16, with the workpiece clamped, is fully immersed in the electrolyte of the electrolytic cell 3 under the drive of the drive component 12, the electrolytic cell 3 is connected to a high-voltage pulse power supply. Using the metal part workpiece as the anode and the pre-set cathode plate inside the electrolytic cell as the cathode, a high-voltage pulse electric field is formed in the electrolyte medium. Due to the concentrated electric field, uniform micro-arc discharge is generated at the corners of the metal parts. The high temperature and pressure at the moment of discharge cause localized melting of the metal at the corners of the parts, and a ceramic reaction occurs with the effective ions in the electrolyte, achieving a micro-arc chamfer at the corners. Throughout the discharge process, the water storage frame 1 continuously cools the electrolytic cell 3, the closed-loop electrolyte filtration circulation system (three sets of filter tubes working as needed) continuously supplies clean electrolyte, and the auxiliary component 16 maintains the precise positioning of the workpiece. These three elements work together to ensure the uniformity of the micro-arc discharge, resulting in a smooth and dense chamfered surface at the corners of the metal parts, meeting the requirements for metal parts in equipment. The chamfering process requires that after the micro-arc chamfering process of the metal parts is completed, the hydraulic rod 1202 of the drive assembly 12 extends, driving the top plate 1203 and the auxiliary assembly 16 to rise and fall, removing the chamfered workpiece from the electrolyte in the electrolytic cell 3. The operator can directly remove the processed metal parts from between the upper clamping plate 1604 and the lower clamping plate 1606 of the auxiliary assembly 16. At the same time, the fluoroplastic self-priming pump 8 and all valves 13 can be closed to cut off the electrolyte circulation loop, realizing the recovery and retention of electrolyte in the electrolytic cell 3 for reuse in subsequent processes. If the electrolyte needs to be replaced, the waste electrolyte can be discharged through the three pipes 9 and the corresponding filter pipes 11 to complete the electrolyte replacement operation. If only some filter pipes 11 need to be cleaned, the corresponding valves 13 can be closed separately. After cleaning, the valves 13 can be opened to restore the synchronous operation of the three sets of filter pipes 11.
