[0002] In electrochemical jet machining, traditional technology is troubled by uneven Gaussian current distribution on the workpiece surface. From a horizontal perspective, low current density at the edge induces "stray current", corrodes the non-machining area, and reduces machining accuracy. Vertically, a hemispherical profile is formed, which increases material loss and affects shape accuracy. At the same time, due to the need for high current density for oxide film removal, the average removal depth remains at the micron level, making it difficult to achieve nanometer-level high-precision removal.

The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0026] In traditional electrochemical jet machining practice, the typical feature of the current distribution on the workpiece surface is Gaussian distribution, which brings multiple challenges. First, in the lateral dimension, the fluidity of the electrolyte causes the distribution range to spread widely, resulting in stray currents in the edge area due to the low edge current density in the Gaussian current distribution, causing unnecessary dissolution and corrosion in the area that does not need to be treated, significantly reducing the accuracy of the machined surface. Secondly, in the longitudinal level, the Gaussian current distribution tends to shape a hemispherical machining profile, which is not only easy to over-remove materials, causing economic waste, but also directly affects the shape accuracy of the machined part. Traditional methods often use extremely high current density (more than 20A / cm2) to deal with the formation of oxide film during machining. However, under the Gaussian current density distribution, this high current density strategy can often only achieve an average removal depth of micrometers, with limited effect and huge energy consumption. In order to limit the distribution range of the electrolyte, related technologies have tried to use compressed air nozzles or design suction working electrodes, but these methods not only have complex and delicate device structures, increase manufacturing costs, but also have unsatisfactory effects in practical applications, and have failed to fundamentally improve the current distribution problem. Another strategy is to use a mask to protect the non-processed area, but this undoubtedly increases the complexity and time cost of the process steps, and does not address the fundamental problem of Gaussian current distribution.

[0027] Therefore, how to effectively optimize the current distribution to achieve uniform current density during electrochemical jet machining and thereby improve machining accuracy has become a difficult problem that needs to be solved urgently.

[0028] In view of this, an embodiment of the present application provides an electrolyte ice ball jet processing system and method, which includes: a frame provided with a clamping device for clamping a workpiece, a spraying device for spraying a solid electrolyte to the workpiece, a power supply device connected to the spraying device and the workpiece, an electrolyte freezing device for freezing a liquid electrolyte into a solid electrolyte, and a driving device for driving the spraying device to move relative to the workpiece, wherein the electrolyte freezing device is arranged on an electrolyte pipeline, the electrolyte pipeline is connected to the spraying device, and the driving device is arranged on the frame. This embodiment can effectively improve the problem of uneven Gaussian current distribution on the surface of the workpiece in traditional electrochemical jet processing by using a solid electrolyte for jet processing, and significantly improve the processing accuracy. Specifically, the uniform spraying of the solid electrolyte helps to achieve a more uniform distribution of the current density, thereby significantly reducing the corrosion of the non-processing area and improving the surface accuracy. Furthermore, the uniform spraying of the solid electrolyte and the improvement of the current distribution can reduce unnecessary material loss, thereby improving the shape accuracy of the processed part. In addition, the shape, size and injection speed of the solid electrolyte can be more easily and precisely controlled by adjusting the system, thus ensuring the controllability and stability of the entire processing process.

[0029] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0030] See also Figure 1 , Figure 1 : is a schematic diagram of the structure of the electrolyte ice ball jet processing system provided in an embodiment of the present application. The electrolyte ice ball jet processing system integrates multiple key components, which are arranged on the frame and work together to achieve efficient and precise processing of the workpiece 10. These core components include: a spray device, which is responsible for accurately spraying solid electrolyte onto the workpiece; a power supply device 110, one end of which is connected to the spray device and the other end is connected to the workpiece 10, which can build an electric field environment between the spray device and the workpiece 10; an electrolyte freezing device 120, which is installed on the electrolyte pipeline and can efficiently convert liquid electrolyte into solid electrolyte 20, and directly transport it to the spray device through the electrolyte pipeline; and a driving device installed on the frame, which can drive the spray device to move relative to the workpiece according to a preset trajectory. In addition, the frame is also equipped with a workbench 100, on which a clamping device 130 is provided, which is used to firmly clamp the workpiece 10 to ensure the stability and accuracy of the processing process.

[0031] In a feasible embodiment, a nozzle 140 for spraying the solid electrolyte 20 is provided on the spray device, and the position of the nozzle 140 corresponds precisely to the position of the clamping device 130, ensuring that the solid electrolyte 20 can be accurately sprayed onto the surface of the workpiece 10 clamped thereon. Before processing, it is only necessary to place the workpiece 10 to be processed in the clamping device 130 and tighten it, and then connect the nozzle 140 to the negative pole of the power supply device 110 through the cathode connection line 30, and at the same time connect the workpiece 10 to the positive pole of the power supply device 110 through the anode connection line 40 to build a complete electrical circuit. After everything is ready, the system starts and enters the electrochemical jet processing stage. At this time, the electrolyte freezing device 120 starts to work, freezes the liquid electrolyte into a solid electrolyte 20, and transports it to the nozzle 140 through the electrolyte pipeline. The nozzle 140 sprays the solid electrolyte 20 onto the surface of the workpiece 10 at a stable flow rate and precise direction. Between the nozzle 140 and the workpiece 10, the electric field constructed by the power supply device 110 begins to work. With the spraying of the solid electrolyte 20, the electrochemical reaction in the electric field is activated, causing the expected chemical changes or physical removal on the surface of the workpiece 10, thereby achieving the processing purpose. During the entire processing process, the drive device can drive the nozzle 140 to move precisely relative to the workpiece 10 according to the preset processing path and speed, ensuring full coverage of the processing area and improved processing accuracy. At the same time, the uniform spraying of the solid electrolyte 20 and the balanced distribution of the current density effectively reduce the corrosion of the non-processing area and improve the processing accuracy.

[0032] In a feasible embodiment, the clamping device 130 can flexibly adopt a three-jaw or four-jaw clamp design. These clamps are stable, reliable and easy to operate, and can effectively clamp and fix the workpiece to be processed, ensuring that the workpiece maintains a stable position and posture during the processing, thereby further improving the processing accuracy and efficiency.

[0033] In a possible embodiment, if Figure 1 As shown, the frame is provided with an electrolyte recovery tank 150, which can be placed directly below the clamping device 130 and is closely connected to the electrolyte pipeline to form a closed-loop electrolyte circulation system. When the nozzle 140 accurately sprays the solid electrolyte 20 onto the surface of the workpiece 10, these solid electrolytes 20 react with the workpiece 10 under the action of the electric field. At this time, the electrolyte recovery tank 150 can effectively collect the electrolyte after the electrolysis reaction to prevent it from overflowing everywhere. In particular, the bottom of the electrolyte recovery tank 150 adopts an inclined structure. This design uses the natural effect of gravity to cause the collected electrolyte to gather autonomously at the bottom of the tank, which is convenient for subsequent processing. Through the connection of the electrolyte pipeline, the recovered electrolyte can be smoothly transported to the electrolyte freezing device 120 for regeneration and other treatments, and finally the electrolyte can be recycled.

[0034] In a feasible embodiment, the electrolyte pipeline includes a first electrolyte recovery pipeline 160 and a second electrolyte recovery pipeline 170, which are respectively located on both sides of the electrolyte tank 180, forming two main paths for electrolyte circulation. The electrolyte tank 180 is connected to the two recovery pipelines to ensure the smooth flow and efficient management of the electrolyte. Specifically, one end of the first electrolyte recovery pipeline 160 is directly connected to the electrolyte recovery tank 150, which is responsible for extracting the processed electrolyte from the recovery tank. The other end of the pipeline is closely connected to the electrolyte tank 180, realizing the collection and storage of the electrolyte. In order to enhance the efficiency and controllability of this process, the first electrolyte recovery pipeline 160 is specially configured with a first liquid return device 161. The first liquid return device 161 can pump the electrolyte, thereby ensuring that the electrolyte in the electrolyte recovery tank 150 can flow into the electrolyte tank 180 stably and efficiently, laying the foundation for subsequent reuse. On the other hand, the second electrolyte recovery pipeline 170 can transport the electrolyte from the electrolyte tank 180 to the injection device. Specifically, one end of the second electrolyte recovery pipeline 170 is connected to the electrolyte tank 180 and is responsible for extracting the processed electrolyte (i.e., the solid electrolyte 20) from the tank; while the other end is closely connected to the injection device to provide a continuous supply of electrolyte for the electrolytic processing process. In addition, the second electrolyte recovery pipeline 170 is also equipped with a second liquid return device 171, which is responsible for pumping the solid electrolyte 20 from the electrolyte tank 180 to the injection device, further simplifying the electrolyte circulation process and improving the automation level and operation efficiency of the entire processing system.

[0035] In a feasible embodiment, the electrolyte tank 180 incorporates the dual functions of the electrolyte freezing device 120 and the filtering device to optimize the recycling process of the electrolyte. Specifically, the electrolyte freezing device 120 can be directly installed inside the electrolyte tank 180, and the filtering device, as a key link in the electrolyte treatment, can also be set in the box. In the treatment of the recovered electrolyte, the filtering device can filter out the solid products (such as oxides, sediments, etc.) produced during the electrochemical reaction from the electrolyte to ensure the purity and recycling value of the electrolyte. The filtered electrolyte is then injected into the electrolyte freezing device 120. In the electrolyte freezing device 120, the low temperature environment causes the electrolyte to solidify rapidly to form a new solid electrolyte 20. This process realizes the continuous renewal and recycling of the solid electrolyte 20. Through continuous filtering, freezing and reuse, the system can ensure sufficient supply and high quality performance of the solid electrolyte 20 during the processing process, thereby improving the efficiency and stability of the entire electrolytic processing process.

[0036] In a feasible embodiment, the injection device introduces a speed regulating device to achieve precise regulation of the speed of the nozzle 140 spraying the solid electrolyte 20. The core components of the speed regulating device include an air source box 191, an air valve 192 and an air pipe 193. The air source box 191 serves as a power source and continuously provides a stable airflow to the nozzle 140 through the air pipe 193. The air valve 192 is installed on the air pipe 193 as a valve for regulating the air flow speed. By adjusting the opening of the air valve 192, the air flow speed entering the nozzle 140 can be flexibly controlled, thereby achieving precise regulation of the injection speed of the solid electrolyte 20. The design of this speed regulating mechanism enables the injection device to quickly respond and adjust the injection speed according to the processing requirements and material properties, thereby optimizing the processing effect. Whether it is a high-precision component that requires fine processing or a batch product that requires efficient production, different processing requirements can be met by adjusting the injection speed. At the same time, the design also improves the controllability and stability of the processing process, laying a solid foundation for the further development of electrolytic processing technology.

[0037] In a feasible embodiment, the driving device integrates three core components, namely, the Y-axis moving platform 201, the Z-axis moving platform 202 and the X-axis moving platform 203, to realize multi-dimensional precise control of the injection device. Specifically, the Y-axis moving platform 201 is firmly mounted on the workbench 100, providing a stable horizontal reference for the entire motion system. The Z-axis moving platform 202 and the X-axis moving platform 203 are arranged inside the frame, and the three work together to realize the free movement of the injection device in three-dimensional space. It is worth noting that the driving device can accurately drive the injection device to perform complex and flexible movements relative to the workpiece 10 according to the preset processing path and speed parameters. Whether it is straight-line advancement, precise positioning, or tracking of complex curves, it can be achieved through the collaborative work of these three platforms. This highly flexible and precise motion control capability enables the injection device to perform precise material removal operations at specific positions on the surface of the workpiece 10, thereby meeting various precision machining needs.

[0038] In a feasible embodiment, the solid electrolyte 20 can be in the form of electrolyte ice balls, thereby greatly improving the selectivity and processing accuracy of jet processing, and at the same time, no system upgrade is required. It should be noted that the advantages of using electrolyte ice balls include at least: (1) Although solidified into an ice ball shape, the solid electrolyte 20 still retains its essential properties as a conductive electrolyte, ensuring that it can effectively conduct current even in the solid state. (2) The electrolyte ice balls automatically connect to form a conductive loop when they come into contact with each other, and the loop is disconnected once they are separated. This feature ensures that even if a discrete single ice ball comes into contact with the surface of the workpiece, it will not easily trigger an unexpected chemical reaction, thereby greatly improving the accuracy of the processed surface. (3) When the ice ball comes into contact with the surface of the workpiece and connects into a loop, the continuous Gaussian current distribution that may have been generated is cleverly discretized into a point distribution. This change further optimizes the distribution of current in the processing area and improves the controllability of the processing process. (4) The contact point between the ice ball and the workpiece surface is dynamically moving, which brings dual advantages: first, uniform material removal is achieved through uniformly distributed current; second, the dynamic contact process minimizes the amount of material removed at a time, thereby achieving nano-level micro-machining accuracy. In addition, the rolling of the ice ball can effectively remove the products generated during the processing from the working area, keeping the processing environment clean. (5) These electrolyte ice balls can be recycled through the process of melting, filtering and re-solidification.

[0039] The working process of the electrolyte ice ball jet machining system is explained below using a specific example.

[0040] First, the workpiece 10 is placed in the clamping device 130 and firmly fastened to ensure stability during the processing. Next, the nozzle 140 is connected to the negative electrode of the power supply device 110 through the cathode connection line 30, and the workpiece 10 is connected to the positive electrode of the power supply device 110 through the anode connection line 40. At this moment, the system is fully ready and the electrochemical reaction process is about to start. With the activation of the power supply device 110, the injection device is immediately started, and the Y-axis moving platform 201, the Z-axis moving platform 202 and the X-axis moving platform 203 begin to work closely together. They accurately guide the injection device to perform a fine motion trajectory on the surface of the workpiece 10 according to the pre-set processing path and speed parameters. When the electrolyte ice ball hits the surface of the workpiece 10 at high speed and precision, the electrochemical reaction occurs immediately, and the metal material on the surface of the workpiece 10 is gradually and evenly removed, thereby accurately carving out the required fine structure or contour. During this process, the first liquid return device 161 is started, and it extracts the used electrolyte ice ball from the electrolyte recovery tank 150 through the first electrolyte recovery pipeline 160, and safely sends it to the electrolyte tank 180 for subsequent treatment. In the electrolyte tank 180, the filtering device quickly separates the solid impurities (such as metal oxides, sediments, etc.) generated by the electrochemical reaction from the electrolyte to ensure the purity and efficient use of the electrolyte. Subsequently, the filtered pure electrolyte is re-injected into the electrolyte freezing device 120 and solidified into fresh electrolyte ice balls again, realizing the closed-loop recycling of the electrolyte and the continuous supply of ice balls. At the same time, the second liquid return device 171 and the second electrolyte recovery pipeline 170 work together to accurately and accurately send the fresh electrolyte ice balls to the injection device. At this time, the high-pressure gas source in the gas source box 191 provides a stable and high-speed airflow to the injection device through the gas pipe 193, and the airflow speed is controlled in real time by the precise gas valve 192 to ensure that the electrolyte ice ball can be sprayed onto the surface of the workpiece 10 at the optimal speed, achieving efficient and accurate processing results. In the entire processing flow, the continuous and stable supply of electrolyte ice balls, the precise control of the injection speed, and the multi-dimensional precise control of the injection device complement each other and jointly ensure the high precision, high efficiency and high quality of the processing process.

[0041] See also Figure 2 , Figure 2 : is a flow chart of the electrolyte ice ball jet processing method provided in the embodiment of the present application. The method can be applied to the electrolyte ice ball jet processing system described above. The method comprises the steps of:

[0042] Step 210: freezing the liquid electrolyte into a solid electrolyte by an electrolyte freezing device;

[0043] Step 220: applying an electric field between the workpiece on the clamping device and the spraying device through the power supply device;

[0044] Step 230: spraying the solid electrolyte onto the workpiece on the clamping device at a preset spraying speed through the spraying device;

[0045] Step 240: The clamping device and the injection device are driven by the driving device to move relative to each other, so that the workpiece and the solid electrolyte undergo an electrolytic reaction under the action of the electric field.

[0046] In a feasible embodiment, a specific process of driving the clamping device and the injection device to move relative to each other by a driving device is performed, aiming at causing an electrolytic reaction between the workpiece and the solid electrolyte under the action of an electric field. This process includes: obtaining a motion trajectory; controlling the driving device to drive the clamping device and the injection device to move relative to each other according to the motion trajectory. Specifically, after the workpiece is safely and firmly clamped by the clamping device, the power supply device is activated to ensure that a stable electric field is established between the workpiece and the injection device. On this basis, the motion trajectory of the injection device is pre-planned and set, and then the driving device is used to drive the injection device to perform precise relative motion with the clamping device at a predetermined path and speed according to this trajectory, thereby achieving precise material removal operations at a specified position, ensuring the efficiency and accuracy of the processing process.

[0047] It should be noted that the electrolyte ice ball jet processing method proposed in this embodiment can be integrated and efficiently operated in the electrolyte ice ball jet processing system described previously, and its implementation method is closely aligned with the system, and they jointly exhibit functional characteristics. Therefore, the method of this embodiment and the previously described electrolyte ice ball jet processing system show a high degree of consistency and complementarity in terms of technical principles and the technical effects brought about. In order to avoid unnecessary content redundancy, the technical details and advantages shared by the two will not be repeated here.

[0048] See also Figure 3 , Figure 3: It is a schematic diagram of electrolyte ice ball jet processing provided in an embodiment of the present application. A solid electrolyte (electrolyte ice ball) is sprayed onto the surface of a workpiece through a nozzle. At a suitable spraying speed, the electrolyte ice balls in the gap between the nozzle and the surface of the workpiece can be closely connected to construct efficient charge transfer paths, thereby forming a complete electrolysis circuit. It is understandable that the removal of material follows the principle of electrochemical dissolution and is limited to the area where the electrolyte ice ball is in direct contact with the surface of the workpiece. It is worth noting that each contact point has an independent electrolysis circuit, which ensures the uniformity and consistency of material removal and effectively avoids stray corrosion caused by low current density. In particular, once the connection between the electrolyte ice balls is disconnected, the corresponding electrolysis circuit is immediately interrupted, and even if the electrolyte ice ball is still in contact with the surface of the workpiece, no further material removal will occur. This feature greatly enhances the selectivity and controllability of the machining process, so that the machining area is precisely limited to a limited range directly aimed at the nozzle, thereby achieving high-precision and high-selectivity machining of the target area.

[0049] See also Figure 4 , Figure 4 : is a schematic diagram of a material removal mode on a rough contour provided by an embodiment of the present application. In this process, the movement of the electrolyte ice ball on the surface of the workpiece includes translation and rotation. Specifically, the diameter of the electrolyte ice ball can be designed to be much larger than the gap between the peaks of the rough contour, thereby ensuring that material removal occurs only in the peak area of ​​the rough contour in contact with the electrolyte ice ball. In particular, the translational movement of the electrolyte ice ball not only achieves high efficiency similar to mechanical cutting, but also avoids the rounded corner problem that may be introduced by traditional electrical machining, thereby achieving high selectivity in machining depth. This removal mode can not only significantly improve the surface accuracy of the workpiece, but also better retain its original geometric accuracy, meeting the requirements of high-precision machining. In addition, the rotation of the electrolyte ice ball on the surface of the workpiece plays a dual key role: on the one hand, it can effectively remove the electrolysis products from the contact point, preventing the accumulation of products from interfering with the machining process; on the other hand, its rotation process can continuously bring fresh electrolyte to the contact point, ensuring the continuous, efficient and stable progress of the anodic dissolution reaction. This self-cleaning and fluid supply mechanism not only improves processing efficiency, but also ensures the cleanliness and uniformity of the processed surface.

[0050] See also Figure 5 , Figure 5 It is a schematic diagram of a material removal mode on a smooth contour provided in an embodiment of the present application. Figure 4The removal mode in the process can also achieve precise layer-by-layer stripping of materials on smooth surfaces. It is worth noting that by adjusting the composition and concentration of the electrolyte and the size of the processing current, the single processing depth can be accurately controlled. Furthermore, the dynamic contact mechanism in the electrolyte ice ball jet processing demonstrates its ability to remove nanoscale materials on smooth contours. This feature enables the processing process to go deep into the microscopic level, achieving a significant improvement in surface quality and meeting the standards for high-precision and high-quality processing requirements.
