DETAILED DESCRIPTION

[0010] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only an embodiment of a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0011] Embodiment 1 See also Figure 1-Figure 5 This embodiment provides an electrolysis method based on a machine tool programmable control system, comprising: S101, configuring three positive and negative pulse combination types, wherein the three positive and negative pulse combination types correspond to different electrolyte states and workpiece processing complexities; S102, selecting one of the three positive and negative pulse combination types that is adapted to the electrolyte state and the workpiece processing complexity according to the electrolyte state and the workpiece processing complexity; S103. Control the first electrolytic machine tool and the second electrolytic machine tool to perform electrolytic processing on the workpieces at a plurality of workstations according to the selected positive and negative pulse combination type adapted to the electrolyte state and the workpiece processing complexity; the first electrolytic machine tool and the second electrolytic machine tool are separately arranged, the plurality of workstations are arranged on the first electrolytic machine tool, and when the second electrolytic machine tool is assembled to one side of the first electrolytic machine tool, it cooperates with the first electrolytic machine tool to perform electrolytic processing on the workpieces at the plurality of workstations.

[0012] It should be noted that, in the present embodiment, three positive and negative pulse combination types are configured, and the three positive and negative pulse combination types correspond to different electrolyte states and workpiece processing complexities. According to the electrolyte state and the workpiece processing complexity, one of the three positive and negative pulse combination types is selected to adapt to the electrolyte state and the workpiece processing complexity. According to the selected positive and negative pulse combination type that adapts to the electrolyte state and the workpiece processing complexity, the first electrolytic machine tool and the second electrolytic machine tool are controlled to perform electrolytic processing on workpieces on multiple stations. The first electrolytic machine tool and the second electrolytic machine tool are separately arranged, and the multiple stations are arranged on the first electrolytic machine tool. When the second electrolytic machine tool is assembled to one side of the first electrolytic machine tool, it cooperates with the first electrolytic machine tool to perform electrolytic processing on the workpieces on the multiple stations, thereby realizing multi-station workpiece electrolytic processing. Moreover, the second electrolytic machine tool and the first electrolytic machine tool can be used in combination or separately, which greatly reduces the electrolysis cost. In addition, the configuration and selection of three types of positive and negative pulse combinations can improve the intelligence level of workpiece electrolytic machining and improve the quality stability of workpiece machining.

[0013] In some preferred embodiments, after selecting one of the three positive and negative pulse combination types, the power supply of the first electrolytic machine tool is controlled to provide positive pulses to the workpieces on the multiple stations, and / or the power supply of the second electrolytic machine tool is controlled to provide positive pulses to the workpieces on the multiple stations, and electrolytic processing is performed on the workpieces on the multiple stations; during the processing, a preset time period is selected to control the power supply of the first electrolytic machine tool to provide negative pulses to the workpieces on the multiple stations, and / or the power supply of the second electrolytic machine tool is controlled to provide negative pulses to the workpieces on the multiple stations, and the electrodes of the first electrolytic machine tool and the second electrolytic machine tool are repaired. It should be noted that during the electrolysis process, the positive and negative poles of the power supply are respectively connected to the workpiece and the electrode to form an electrolytic circuit. After the electrode performs electrolytic processing on the workpiece for a long time, the residues generated by the workpiece will adhere to the surface of the electrode, resulting in a decrease in processing accuracy. In this embodiment, during the processing, a preset time period is selected to control the power supply of the first electrolytic machine tool to provide a negative pulse to the workpieces on the multiple workstations, and / or the power supply of the second electrolytic machine tool is controlled to provide a negative pulse to the workpieces on the multiple workstations, and the electrodes of the first electrolytic machine tool and the second electrolytic machine tool are repaired, thereby eliminating the residues on the electrodes and improving the processing accuracy of the workpieces.

[0014] In some preferred embodiments, the electrode repair time for repairing the electrodes of the first electrolytic machine tool and the second electrolytic machine tool is less than the workpiece processing time when the workpieces on the multiple stations are electrolytically processed; the negative pulse voltage value for repairing the electrodes of the first electrolytic machine tool and the second electrolytic machine tool is less than the positive pulse voltage value for electrolytically processing the workpieces on the multiple stations. It should be noted that if the electrode repair time is longer than the workpiece processing time, the electrolytic machine tool will not be able to continue to process the workpiece during the repair period, thereby increasing the downtime and reducing the utilization rate and overall processing efficiency of the equipment. Therefore, designing the electrode repair time to be shorter than the workpiece processing time can maximize the utilization rate of the equipment, complete the maintenance of the electrode as soon as possible while completing the electrolytic processing of the workpiece, and ensure the continuity of the processing process. By shortening the electrode repair time, a good synchronous operation can be formed with the workpiece processing time, so that the repair and processing can be seamlessly connected, ensuring that the equipment is in an efficient working state in each working cycle, reducing the waiting time of the workpiece at the processing station, and improving the overall output. When repairing the electrode, the negative pulse is mainly used to remove the residue attached to the electrode surface. This process does not require a high voltage like when processing the workpiece. By designing the negative pulse voltage value to be lower than the positive pulse, the electrode can be effectively cleaned without producing excessive electrochemical reactions, avoiding unnecessary interference to the surrounding workpieces and processing environment. The lower negative pulse voltage helps to reduce the impact on the electrode itself, thereby extending the service life of the electrode. While keeping the electrode surface clean, it can also reduce the wear rate of the electrode and reduce the maintenance and replacement costs of the equipment. The negative pulse voltage value of the repair electrode is lower than the positive pulse voltage value during processing, and this setting also meets the energy-saving requirements. During the electrode repair process, by reducing power consumption, the energy use cost can be reduced while ensuring the repair effect, thereby improving the overall economic benefits of the equipment.

[0015] In some further preferred embodiments, when selecting the positive and negative pulse combination type according to the electrolyte state and the complexity of workpiece processing, when the pH value of the electrolyte is in a neutral environment, the type A positive and negative pulse combination type is selected; when the pH value of the electrolyte is in a weakly acidic environment, the type B positive and negative pulse combination type is selected; if the complexity of workpiece processing falls within a preset complexity range, the type C positive and negative pulse combination type is selected; the number and occurrence sequence of positive and negative pulses in the type A positive and negative pulse combination type, the type B positive and negative pulse combination type, and the type C positive and negative pulse combination type are different. It should be noted that when the pH value of the electrolyte is neutral, this environment is suitable for a mild electrolysis process, so the type A positive and negative pulse combination type is selected. The type A positive and negative pulse combination type includes a preset smaller number of negative pulses, and the interval between the positive pulse and the negative pulse is a preset larger interval, ensuring that the processing of the workpiece can proceed smoothly in a neutral environment, avoiding excessive electrolysis reactions that lead to excessive removal or damage to the workpiece surface. For example: 5 positive pulses followed by 1 negative pulse, each positive pulse lasts 2 seconds, the negative pulse lasts 0.5 seconds, and the cycle is 12 seconds. In this mode, the negative pulses are less and shorter, which is suitable for mild electrolysis in a neutral electrolyte environment. In addition, when the electrolyte is in a weakly acidic environment, the B-type pulse combination type is selected. The intensity of the electrolytic reaction will increase accordingly, so the B-type pulse combination type contains more negative pulses than the A-type positive and negative pulse combination type, and the frequency of negative pulses is higher than that of the A-type positive and negative pulse combination type, and the interval between positive and negative pulses is shorter than that of the A-type positive and negative pulse combination type. This setting ensures effective control of the processing beat and timely repair of the electrode. For example: 2 positive pulses followed by 2 negative pulses, each positive pulse and negative pulse lasts 1 second each, and the cycle is 8 seconds. This rapid alternation of pulses controls the processing rate and protects the workpiece and electrode. In addition, when the processing complexity of the workpiece falls within the preset complexity range, the C-type positive and negative pulse combination type is selected. The complexity of the workpiece determines the accuracy and control requirements of the electrolysis process. The C-type combination includes preset pulse timings, such as frequent alternation of positive and negative pulses, to ensure good surface processing effects and processing accuracy during high-complexity processing. For example: 1 positive pulse is followed by 1 negative pulse, each positive pulse lasts 1.5 seconds, the negative pulse lasts 1 second, and the cycle period is 5 seconds. This mode is more suitable for the fine processing of complex workpieces, ensuring uniform surface electrolysis during processing and achieving fine control effects. It should be noted that in this embodiment, the pulse type is selected according to the pH value of the electrolyte and the processing complexity of the workpiece, and can be optimized for different processing environments and workpiece characteristics. This personalized processing method improves the adaptability and flexibility of the electrolysis process. By optimizing the frequency and timing of positive and negative pulses, the consistency and accuracy of the workpiece surface can be maintained under different processing conditions. At the same time, the reasonable setting of the frequency and timing of negative pulses can repair the electrode in a timely and effective manner and extend the service life of the electrode.At the same time, by precisely controlling the timing of the pulses, the intensity of the electrolytic reaction can be precisely controlled to ensure the consistency of processing accuracy and processing quality.

[0016] In some preferred embodiments, the first electrolysis machine tool 1 includes a planar workpiece station 11, a curved workpiece station 12, and a gantry electrolysis electrode mechanism 13 located above the planar workpiece station 11 and the curved workpiece station 12, which are arranged on the first machine platform 10; the gantry electrolysis electrode mechanism 13 is used to electrolytically process the front of the planar workpiece on the planar workpiece station 11, and is also used to electrolytically process the side wall of the curved workpiece on the curved workpiece station 12; when the second electrolysis machine tool 2 is assembled to one side of the curved workpiece station 12, it cooperates with the first electrolysis machine tool 1 to electrolytically process the side wall of the curved workpiece on the curved workpiece station 12.

[0017] It should be noted that, in the present embodiment, the first electrolysis machine tool 1 and the second electrolysis machine tool 2 are independent units and can be used alone or in combination. The split design makes the equipment more flexible and adaptable. Different workpieces can choose suitable electrolysis machine tools for processing, or they can be used in combination to expand the application range of the equipment. In addition, the first electrolysis machine tool 1 is provided with a plane workpiece station 11 and a curved workpiece station 12, and is equipped with a gantry electrolysis electrode mechanism 13. Such a configuration enables the same machine tool to process different types of workpieces, including plane and curved workpieces. This not only improves the versatility of the equipment, but also makes the processing process more efficient, and can reduce the time for equipment replacement and workpiece positioning. The design of the gantry electrolysis electrode mechanism 13 can electrolytically process plane and curved workpieces on the same machine tool: the front of the plane workpiece is processed, and the side wall of the curved workpiece can also be processed. This design can make full use of the equipment space, reduce the station adjustment and tooling replacement required when processing different workpieces, and improve the processing efficiency. In addition, when the second electrolytic machine tool 2 is assembled to one side of the curved workpiece station 12 of the first electrolytic machine tool 1, it can cooperate with the first electrolytic machine tool 1 to jointly complete the electrolytic processing of the side wall of the curved workpiece. This collaborative processing method can efficiently process complex workpieces when necessary. Since the second electrolytic machine tool 2 is independent, it can not only cooperate with the first electrolytic machine tool 1, but also be used in combination with other electrolytic machine tools. This modular combination method further reduces the overall use cost of the electrolytic equipment.

[0018] In some preferred embodiments, the workpiece electrolytically processed by the plane workpiece station 11 includes a thin plate-shaped workpiece, and the workpiece electrolytically processed by the curved workpiece station 12 includes a disc-shaped workpiece and a cylindrical workpiece. It should be noted that the thin plate-shaped workpiece usually has a large and flat surface, which is suitable for electrolytic processing on a plane station. Both the disc-shaped and cylindrical workpieces have curved surfaces, which require specific electrode mechanisms for processing to ensure uniform distribution of the electrolyte and stability of the electrolytic current. The design of the curved workpiece station 12 is precisely to meet this demand, and its electrode mechanism can adapt to different curved surface shapes, thereby ensuring high-quality electrolytic effects during processing. For example, the plane workpiece station 11 can adopt a planar electrode design to make the electrolytic processing area more uniform; while the curved workpiece station 12 can adopt an arc or annular electrode to better fit and cover the side wall of the disc or cylindrical workpiece to achieve the best electrolytic effect.

[0019] In some preferred embodiments, the planar workpiece station 11 is provided with a planar electrolysis platform 14; the planar electrolysis platform 14 is located on the table of the first machine 10, and is used to place the planar workpiece to wait for the gantry electrolysis electrode mechanism 13 to electrolytically process the front of the planar workpiece. It should be noted that the planar workpiece usually needs to maintain a high degree of stability and positioning accuracy during the processing. The planar electrolysis platform is provided to provide a stable placement surface for the planar workpiece, ensuring that the workpiece will not move or offset during the processing, thereby improving the processing accuracy. At the same time, the planar electrolysis platform 14 not only provides a stable surface for placing the workpiece, but also helps to optimize the flow of the electrolyte. During the electrolytic processing, the electrolyte needs to evenly cover the surface of the workpiece to ensure the uniformity of the electrolytic reaction. The planar platform can more easily control the flow path of the electrolyte, so that the electrolyte is evenly distributed on the surface of the workpiece, thereby improving the electrolysis effect. In addition, since the gantry electrolysis electrode mechanism 13 electrolytically processes the planar workpiece from above, the workpiece needs to remain stable and exposed in the working area of ​​the electrode mechanism during the processing. Placing the workpiece on a flat electrolysis platform and located on the tabletop of the first machine platform 10 can ensure that the workpiece is always located within the effective working area of ​​the gantry electrolysis electrode mechanism 13 .

[0020] In some preferred embodiments, the curved workpiece station 12 is provided with an electrolytic machining turntable 15; the electrolytic machining turntable 15 is located on the table of the first machine 10 and on one side of the planar electrolytic platform 14, and is used to place the curved workpiece to wait for the gantry electrolytic electrode mechanism 13 to electrolytically machine the side of the curved workpiece. Further, the electrolytic machining turntable 15 includes a support table 150 and a column turntable 151; the support table 150 is arranged on the table of the first machine 10; the column turntable 151 is arranged on the support table 150, and is used to place the curved workpiece to wait for the gantry electrolytic electrode mechanism 13 to electrolytically machine the side of the curved workpiece; during the electrolytic machining process, the column turntable 151 rotates on the support table 150 according to a preset rotation angle, so that different positions of the side of the curved workpiece are subjected to electrolytic machining. It should be noted that the side of the curved workpiece (such as a disc-shaped or cylindrical workpiece) is a surrounding surface, and the electrolytic electrode at a single position cannot cover the entire side at one time. By setting the cylindrical turntable 151, the workpiece can be rotated during the electrolytic machining process, so that the gantry electrolytic electrode mechanism 13 can gradually cover different positions on the side of the curved workpiece, and achieve all-round uniform electrolytic machining. The design of the electrolytic machining turntable 15 enables the equipment to process curved workpieces of different shapes and sizes. The combination of the support table 150 and the cylindrical turntable 151 can adjust the support and fixing method to meet the placement and fixing requirements of various curved workpieces.

[0021] In some preferred embodiments, the second electrolytic machine tool 2 includes a second machine table 20 and an electrolytic processing mechanism 21, and the electrolytic processing mechanism 21 is arranged on the second machine table 20; when the second electrolytic machine tool 2 is assembled to one side of the curved workpiece station 12, the electrolytic processing mechanism 21 cooperates with the first electrolytic machine tool 1 to electrolytically process the side wall of the curved workpiece on the curved workpiece station 12. It should be noted that the independent design of the second electrolytic machine tool 2 enables it to be flexibly cooperated with the first electrolytic machine tool 1 or used alone. This modular design enables the equipment to be freely combined according to actual processing requirements, thereby expanding the processing adaptability of the equipment. When the second electrolytic machine tool 2 cooperates with the first electrolytic machine tool 1, the side wall of the curved workpiece can be synchronously processed. This simultaneous processing method can significantly shorten the processing time and improve production efficiency. For example, when processing large curved workpieces, it may take a long time to complete the processing by relying on only one electrolytic machine tool. By introducing the second electrolytic machine tool 2, electrolytic processing can be performed simultaneously at different parts, thereby improving the overall production speed and efficiency. For some complex curved workpieces, it may be difficult to achieve uniform electrolytic machining with only one electrode. By setting up the second electrolytic machine 2, additional electrolytic machining mechanisms 21 can be placed at different positions to work synchronously with the electrode of the first electrolytic machine 1 to ensure that each part of the workpiece can receive uniform electrolytic machining.

[0022] In some preferred embodiments, the electrolytic machining mechanism 21 includes a Y-axis moving block 210 and an electrolytic machining component 211; the electrolytic machining component 211 is movably connected to the Y-axis moving block 210; the Y-axis moving block 210 is arranged on the second machine 20 and is movably connected to the table of the second machine 20, and the Y-axis moving block 210 drives the electrolytic machining component 211 to move along the Y-axis direction on the table of the second machine 20; the electrolytic machining component 211 moves toward or away from the direction of the curved workpiece station 12 on the Y-axis moving block 210; the direction of the curved workpiece station 12 is the X-axis direction. Further, the electrolytic machining assembly 211 includes a Z-axis driving module 2110 and an electrode electrolytic device 2111; the electrode electrolytic device 2111 is mounted on the Z-axis driving module 2110 and moves along the Z-axis direction under the drive of the Z-axis driving module 2110; the Z-axis driving module 2110 is movably connected to the Y-axis moving block 210. Further, the electrode electrolytic device 2111 includes a Z-axis driving connection block 21110 and a side wall electrolytic turntable 21111; the Z-axis driving connection block 21110 is connected to the Z-axis driving module 2110, and the side wall electrolytic turntable 21111 is connected to the Z-axis driving connection block 21110; an electrode is arranged on the side wall electrolytic turntable 21111, and during the electrolytic machining process, the side wall electrolytic turntable 21111 rotates on the Z-axis driving connection block 21110 according to a preset rotation angle, so that different positions of the side surface of the curved workpiece are subjected to electrolytic machining. It should be noted that by introducing the Y-axis moving block 210 and the Z-axis driving module 2110 in the electrolytic machining mechanism 21, the device can move in multiple axial directions, thereby accurately positioning the position of the electrode. This design can ensure that the electrode can be adjusted according to the shape and size of the workpiece to meet the processing requirements of different curved workpieces. Under the action of the Y-axis moving block 210, the electrolytic machining component 211 can move along the Y-axis to cover different workstation positions or adjust the machining path; the Z-axis driving module 2110 allows the electrode to be adjusted up and down along the Z-axis to adapt to the height change of the side wall of the workpiece to achieve high-precision machining. The multi-axis moving design enables the electrolytic machining mechanism 21 to accurately control the position and angle of the electrode. The Z-axis driving module 2110 can accurately adjust the distance from the electrode to the surface of the workpiece, thereby ensuring the consistency of the electric field strength and the electrolyte distribution during the electrolysis process, and improving the machining accuracy. Through the combined adjustment of the Y-axis and the Z-axis, the electrode can move along different paths and directions, which is particularly important for curved workpieces with complex geometric shapes, and helps to achieve high-precision machining effects. The movable connection between the Y-axis moving block 210 and the electrolytic machining assembly 211 enables the position of the entire mechanism to be flexibly adjusted on the second machine platform 20 .Such a design enables the equipment to realize an automated processing process, automatically adjust the electrode position according to different processing tasks, and improve production efficiency. Driven by the Z-axis drive module 2110, the electrode electrolysis device 2111 can flexibly cope with workpieces of different heights and shapes. This flexibility not only improves the adaptability of the equipment, but also provides convenience for future equipment upgrades and diversification of processing tasks. Electrodes are arranged on the side wall electrolysis turntable 21111, and during the electrolytic processing, the turntable can rotate on the Z-axis drive connection block 21110 according to a preset rotation angle. This design ensures that the electrode can conform to the curvature and shape of the curved workpiece, gradually cover the side wall surface of the workpiece, and ensure that the electrolytic processing process is uniform.

[0023] In some preferred embodiments, the gantry electrolysis electrode mechanism 13 includes a gantry 130 and a suspended electrolysis device 131; the gantry 130 is installed on the table of the first machine platform 10; the suspended electrolysis device 131 is suspended on the gantry 130, and is used to electrolytically process the front of the planar workpiece on the planar workpiece station 11, and is also used to electrolytically process the side wall of the curved workpiece on the curved workpiece station 12. It should be noted that the design of the gantry electrolysis electrode mechanism 13 enables it to process different types of workpieces on the same device. The suspended electrolysis device 131 can process the front of the planar workpiece, and can also adjust the height and position to process the side wall of the curved workpiece. In this way, one device can complete multiple processing tasks, reducing the need for multiple devices, thereby improving the utilization rate of the equipment and the overall efficiency of the production line. The suspended electrolysis device 131 can be moved along the track of the gantry 130 and adjust the position and height by being installed on the gantry 130. This design allows the electrolysis device to move flexibly in multiple directions, such as X, Y, and Z, so that it can accurately align with the processing area of ​​the workpiece. Whether it is the front of a flat workpiece or the side wall of a curved workpiece, accurate positioning and processing can be achieved. The gantry 130 is installed on the table of the first machine 10, providing a stable support structure for the suspended electrolysis device 131, ensuring the stability and accuracy of the electrode during processing.
