Description

Technical Field

[0001] This application relates to the field of special processing technology, and in particular to a system and method for constructing an electrochemical discharge machining process. Background Technology

[0002] Electrochemical discharge machining (EDM) is an effective method commonly used for processing insulating, hard, and brittle materials (such as quartz glass). Its basic principle involves using an electrolytic circuit to form a gas film on a tool electrode. The high temperature and pressure generated by the instantaneous spark discharge within this insulating gas film, combined with physical and chemical actions within the electrolyte, results in material removal. Electrochemical discharge occurs within the gas film that isolates the tool electrode from the electrolyte. During this process, the immersion depth (i.e., the depth to which the tool electrode is immersed from the electrolyte surface) significantly influences gas film formation and the discharge state. Increasing the immersion depth enlarges the discharge channel, increasing the probability of discharge occurring on the sidewalls; however, it also increases the difficulty of forming a complete and stable gas film on the tool electrode surface from the electrolytically generated bubbles. Therefore, a thin immersion depth is required in the electrochemical discharge process to narrow the discharge channel, concentrating the discharge in a smaller area and enabling rapid gas film formation.

[0003] In related technologies, a thin immersion depth needs to be specified when forming an electrochemical discharge process. The main methods for specifying the thin immersion depth are: (1) CCD visual online measurement: After the workpiece is immersed in the electrolyte, the actual immersion depth is measured by visual observation. This method is simple to operate, but since there is no electrolyte replacement measure, the high temperature generated by the discharge will cause the electrolyte to evaporate rapidly, making the processing unable to continue. (2) Fixed height partition method: This improves the structure of the processing liquid tank by using a fixed height partition to divide the processing liquid tank into two parts. The electrolyte is continuously injected into the processing liquid tank. When the electrolyte exceeds the fixed height partition, it will overflow, thereby maintaining a stable immersion depth. The immersion depth can be adjusted by adjusting the height of the fixed height partition or the thickness of the workpiece. However, in actual application, due to the existence of electrolyte surface tension, the electrolyte often cannot form a stable thin layer on the surface of the workpiece and is prone to agglomerate into intermittent liquid droplets, which cannot form a stable discharge path. (3) Laminar flow rinsing method: This method uses a nozzle to rinsing liquid to form a thin, flowing liquid film on the workpiece surface. The thickness of the thin liquid film is adjusted by changing parameters such as the liquid flow rate, distance, and height of the nozzle, thus determining the specified immersion depth. This method is affected by numerous factors, making quantitative control of the liquid film thickness difficult. Furthermore, all three methods are only applicable to planar workpieces and are difficult to apply to the machining of rotating workpieces.

[0004] In summary, the relevant technologies have limited applicability, and the visual measurement method conflicts with the actual process requirements, making it difficult to continue the process. The fixed-height partition method is difficult to form a stable electrolyte film on the workpiece surface, and the laminar flow flushing method is difficult to accurately control the thickness of the liquid film on the workpiece surface. These issues urgently need to be improved. Summary of the Invention

[0007] Optionally, in one embodiment of this application, the electrolyte tank includes: an outer tank; and an inner tank, wherein the inner tank is placed inside the outer tank, and the height of the inner tank wall is greater than the height of the outer tank wall.

[0008] Optionally, in one embodiment of this application, it further includes: a circulating liquid pump, used to connect the inner tank and the outer tank, and to control the circulation of electrolyte in the inner tank and the outer tank, so that the liquid level of the electrolyte in the inner tank meets the second preset stability condition.

[0009] Optionally, in one embodiment of this application, the target workpiece is a rotating, non-conductive workpiece.

[0010] Optionally, in one embodiment of this application, the electrolyte is hydrophilic to the target workpiece, and the electrolyte contains a fluorescent dye.

[0012] A second aspect of this application provides a method for constructing an electrochemical discharge machining process, comprising the following steps: clamping a target workpiece on a workpiece spindle so that the target workpiece is immersed in an electrolyte in an electrolyte tank; controlling the workpiece spindle to rotate at a target speed so that when the surface of the target workpiece is removed from the electrolyte surface, an electrolyte film satisfying a first preset stability condition is attached to the surface of the target workpiece; adjusting the speed of the workpiece spindle or the relative distance between the target workpiece and the electrolyte surface to detect the thickness of the electrolyte film on the surface of the target workpiece at different speeds or relative distances; detecting the thickness of the electrolyte film attached to the surface of the target workpiece and detecting the electrochemical discharge spark state at each electrolyte film thickness; generating a thickness variation law using the electrolyte film thickness corresponding to each speed or relative distance, and generating a discharge variation law using the electrochemical discharge spark state corresponding to each electrolyte film thickness, so as to construct a corresponding electrochemical discharge machining rotary workpiece process by combining the thickness variation law and the discharge variation law.

[0016] This embodiment utilizes a workpiece spindle to clamp the target workpiece, immersing it in the electrolyte in an electrolyte bath. A control module controls the spindle's rotation, ensuring a stable electrolyte film adheres to the workpiece surface upon extraction from the electrolyte. Electrochemical discharge machining is then performed based on this electrolyte film. An adjustment module regulates the spindle's rotation speed or the relative distance between the workpiece and the electrolyte surface to adjust the electrolyte film thickness.

[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0026] The following description, with reference to the accompanying drawings, outlines a system and method for constructing an electrochemical discharge machining process according to embodiments of this application. Addressing the limitations of the aforementioned related technologies, such as the limited applicability, conflicts between visual measurement methods and actual process requirements leading to unsustainable processing, the difficulty in forming a stable electrolyte film on the workpiece surface using the constant-height partition method, and the difficulty in accurately controlling the electrolyte film thickness on the workpiece surface using the laminar flow flushing method, this application provides a system for constructing an electrochemical discharge machining process. In this system, a workpiece spindle clamps the target workpiece, immerses it in the electrolyte of an electrolyte bath, and a control module controls the rotation of the workpiece spindle. During the processing of the target workpiece, a stable electrolyte film adheres to the surface of the target workpiece when it is removed from the electrolyte surface. An electrolyte film is formed, and electrochemical discharge machining (EDM) is performed on the target workpiece based on the electrolyte film. An adjustment module regulates the spindle speed or the relative distance between the workpiece and the electrolyte surface to adjust the electrolyte film thickness. A detection module monitors the electrolyte film thickness and the electrochemical discharge spark state at each thickness. By combining the thickness variation patterns between electrolyte film thickness and spindle speed or relative distance, and the discharge variation patterns between electrolyte film thickness and electrochemical discharge spark state, a corresponding EDM process for rotating workpieces is constructed. This process is applicable to rotating workpieces, resulting in a wide range of adjustable electrolyte film thickness and simple quantitative control for generating a given electrode immersion depth. This solves the technical problems in related technologies, such as limited applicability, conflicts between visual measurement methods and actual process requirements, difficulty in continuous processing, the inability of the constant-height partition method to form a stable electrolyte film on the workpiece surface, and the difficulty of accurately controlling the electrolyte film thickness on the workpiece surface using laminar flow flushing methods.

[0027] Specifically, Figure 1 This is a schematic diagram of the structure of a system for constructing an electrochemical discharge machining process provided in an embodiment of this application.

[0028] like Figure 1 As shown, the construction system 10 of the electrochemical discharge machining process includes: a workpiece spindle 100, an electrolyte tank 200, a control module 300, an adjustment module 400, a detection module 500, and a construction module 600.

[0029] Specifically, the workpiece spindle 100 is used to clamp the target workpiece.

[0030] In actual execution, the target workpiece can be clamped by the workpiece spindle 100, wherein the target workpiece is a rotary workpiece, so that when the workpiece spindle 100 rotates, the target workpiece can rotate around its own axis under the drive of the workpiece spindle 100.

[0031] To ensure that the target workpiece can stably adhere to the electrolyte film in subsequent processes, the workpiece spindle 100 ensures that the axis of the target workpiece is in a horizontal position after clamping the target workpiece.

[0032] Optionally, in one embodiment of this application, the target workpiece is a rotating, non-conductive workpiece.

[0033] The target workpiece can be made of non-conductive material and is a rotating body so that it can rotate with the workpiece spindle 100 after being clamped.

[0034] Electrolyte tank 200 is used to hold electrolyte so that the target workpiece is partially immersed in the electrolyte.

[0035] The electrolyte tank 200 can be filled with electrolyte, so that the target workpiece is partially immersed in the electrolyte. In subsequent processing, the target workpiece can carry the electrolyte out when it rotates, forming an attached electrolyte film.

[0036] Optionally, in one embodiment of this application, the electrolyte is hydrophilic to the target workpiece, and the electrolyte contains a fluorescent dye.

[0037] In order for the target workpiece to carry out the electrolyte and form an attached electrolyte film when it rotates, the electrolyte and the material of the target workpiece are hydrophilic, that is, the contact angle of the electrolyte on the material of the target workpiece is less than 90°.

[0038] The electrolyte may contain fluorescent dyes to facilitate subsequent measurement of the electrolyte membrane thickness.

[0039] Optionally, in one embodiment of this application, the electrolyte tank 200 includes an outer tank and an inner tank.

[0040] The inner tank is located inside the outer tank, and the height of the inner tank wall is greater than the height of the outer tank wall.

[0041] As one possible implementation, the electrolyte tank 200 can be divided into an inner tank and an outer tank, wherein the inner tank is placed inside the outer tank and the height of the inner tank is higher than that of the outer tank.

[0042] Optionally, in one embodiment of this application, the electrochemical discharge processing system 10 further includes a circulating liquid pump.

[0043] The circulating liquid pump is used to connect the inner tank and the outer tank and to control the circulation of electrolyte in the inner tank and the outer tank, so that the electrolyte level in the inner tank meets the second preset stability condition.

[0044] In some embodiments, a circulating liquid pump can be used to pump the electrolyte stored in the outer electrolyte tank into the inner electrolyte tank to ensure the stability of the liquid level in the inner tank.

[0045] The second preset stability condition can be set according to the actual situation such as workpiece size and inner groove size, and no specific restrictions are imposed here.

[0046] The control module 300 is used to control the rotation of the workpiece spindle 100 so that during the processing of the target workpiece, an electrolyte film that meets the first preset stability condition is attached to the surface of the target workpiece when it is extracted from the electrolyte surface, and electrochemical discharge processing of the target workpiece is performed based on the electrolyte film.

[0047] Furthermore, in this embodiment, the control module 300 can control the rotation of the workpiece spindle 100, causing a thin, stable electrolyte film to form on the surface of the target workpiece when it is removed from the electrolyte surface. During processing, after the target workpiece rotates to form a thin electrolyte film, the tool cathode approaches the target workpiece and contacts the liquid film, thus triggering an electrolytic reaction. When electrolytic bubbles gradually accumulate to form a complete gas film, electrochemical discharge occurs to erode the workpiece material, completing the electrochemical discharge machining.

[0048] The adjustment module 400 is used to adjust the rotational speed of the workpiece spindle 100 or the relative distance between the target workpiece and the electrolyte surface.

[0049] It is understandable that different rotational speeds of the workpiece spindle 100 affect the thickness of the electrolyte film carried by the target workpiece. Similarly, the relative distance between the target workpiece and the electrolyte surface, i.e., the depth to which the target workpiece is immersed in the electrolyte, also affects the thickness of the electrolyte film carried by the target workpiece.

[0050] In order to understand the thickness variation law of the electrolyte film, the embodiments of this application can use the adjustment module 400 to adjust the rotation speed of the workpiece spindle 100 or the relative distance between the target workpiece and the electrolyte surface.

[0051] When adjusting the relative distance between the target workpiece and the electrolyte surface, the distance between the electrolyte surface and the target workpiece can be adjusted by adding pads in the electrolyte tank 200 or by adjusting the micro-motion platform, so as to change the immersion depth of the target workpiece.

[0052] The detection module 500 is used to detect the thickness of the electrolyte film attached to the surface of the target workpiece and to detect the electrochemical discharge spark state under each electrolyte film thickness.

[0053] In actual implementation, the embodiments of this application can detect the thickness of the electrolyte film attached to the surface of the target workpiece at different rotation speeds, so as to establish the variation law between rotation speed and electrolyte film thickness;

[0054] Similarly, embodiments of this application can also detect the thickness of the electrolyte film attached to the surface of the target workpiece at different relative distances between the target workpiece and the electrolyte surface, so as to establish the variation law between the relative distance and the electrolyte film thickness.

[0055] The embodiments of this application can also detect the effect of different electrolyte film thicknesses on the electrochemical discharge spark state, so as to facilitate subsequent process construction.

[0056] Optionally, in one embodiment of this application, the detection module 500 includes: a transmitting unit, a capturing unit, and a processing unit.

[0057] The emitting unit is used to emit a planar laser, which irradiates the electrolyte film attached to the target workpiece to induce the fluorescent dye in the electrolyte film to emit fluorescence.

[0058] A capture unit is used to capture image data containing fluorescence.

[0059] The processing unit is used to process image data to obtain the electrolyte film thickness.

[0060] As one possible implementation, the detection module 500 may include an emission unit (such as a continuous solid-state laser), a capture unit (high-definition digital CCD camera), and a processing unit to complete the thickness detection of the electrolyte film.

[0061] For example, in this application embodiment, a continuous solid-state laser can be used as the emitting unit to emit a planar laser. The planar laser is irradiated onto the electrolyte film attached to the target workpiece to induce the fluorescent dye in the electrolyte film to emit fluorescence. The fluorescence can be captured by a camera through a filter, and the thickness of the liquid film can be detected by image processing in the later stage.

[0062] Specifically, the emitting unit can be configured with an orthogonal optical path to the capturing unit. The planar laser emitted by the emitting unit irradiates the thin electrolyte film agitated by the rotating workpiece, thereby inducing the fluorescent dye in the electrolyte film to emit fluorescence. The fluorescence is captured by the capturing unit through a filter, and the contour of the liquid film thickness direction can be obtained through image processing by the processing unit. The physical liquid film thickness can be obtained by multiplying the physical length corresponding to each pixel by the number of pixels.

[0063] The module 600 is used to generate a thickness variation law by utilizing the electrolyte film thickness corresponding to each rotation speed or relative distance, and to generate a discharge variation law by utilizing the electrochemical discharge spark state corresponding to each electrolyte film thickness, so as to combine the thickness variation law and the discharge variation law to construct a corresponding electrochemical discharge machining process for rotating workpieces.

[0064] Furthermore, the construction module 600 can generate the electrolyte film thickness variation law based on the rotation speed-thickness variation law generated by the electrolyte film thickness at different rotation speeds and the distance-thickness variation law generated by the electrolyte film thickness at different relative distances.

[0065] The building module 600 can also generate discharge change patterns based on the electrochemical discharge spark states corresponding to different electrolyte film thicknesses.

[0066] By combining the thickness variation law and the discharge variation law, the embodiments of this application can clarify the influence of different settings on the electrolyte film thickness and the influence of different electrolyte film thicknesses on electrochemical machining. This allows the established electrochemical discharge machining process for rotating workpieces to be adjusted according to the machining requirements of the workpieces to ensure the machining accuracy of the workpieces.

[0067] Combination Figures 2 to 4 As shown, the working principle of the construction system for the electrochemical discharge processing technology of this application is explained in detail with reference to one embodiment.

[0068] like Figure 2 (a) and Figure 2 As shown in (b) of this application, the embodiments may include: target workpiece 11, workpiece spindle 100, workpiece spindle clamping mechanism 101, electrolyte tank 200, inner tank 201, outer tank 202, adjustment module 400, and circulating liquid pump 700.

[0069] Taking a cylindrical rotating quartz workpiece as an example, it includes a small cylindrical end held by the clamp of the workpiece spindle clamping mechanism 101 and a large cylindrical end for immersion and rotation. According to the embodiments of this application, the step of forming a thin liquid film on its surface includes: (1) clamping the rotating workpiece on the workpiece spindle 100, so that the workpiece axis is in a horizontal position; (2) filling the electrolyte tank 200 with electrolyte, immersing the lower part of the workpiece axis into the electrolyte, and turning on the circulating pump 700 to circulate the electrolyte in the inner tank 201 and outer tank 202 of the electrolyte tank 200; (3) rotating the workpiece spindle 100, utilizing the hydrophilic properties of the workpiece to create a thin and stable electrolyte film on its surface as it rotates away from the electrolyte surface. The height of the electrolyte tank 200 can be adjusted by the adjustment module 400, such as a micro-adjustment mechanism for tank height, thereby adjusting the immersion depth of the cylindrical workpiece.

[0070] like Figure 3As shown, when using laser-induced fluorescence to detect electrolyte film thickness, the device may include a 532nm continuous solid-state laser (emitting unit 501), a high-definition digital CCD camera (capture unit 502), a filter 503, an electrolyte containing Rhodamine B fluorescent dye, an oscilloscope, etc. The high-definition digital CCD camera (capture unit 502) and the continuous solid-state laser (emitting unit 501) are arranged in orthogonal optical paths. The planar laser emitted by the continuous solid-state laser (emitting unit 501) irradiates the thin electrolyte film stirred up by the rotating workpiece, thereby inducing the fluorescent dye in the electrolyte film to emit fluorescence. The fluorescence is captured by the high-definition digital CCD camera (capture unit 502) through the filter 503. Subsequently, image processing methods such as grayscale conversion and image segmentation are used to detect the contour of the liquid film thickness direction. The physical liquid film thickness can be obtained by multiplying the physical length corresponding to each pixel by the number of pixels.

[0071] like Figure 4 (a) and Figure 4 As shown in (b), when applying the embodiments of this application to an electrochemical discharge machining system for workpiece machining, an electrolytic circuit can be constructed based on a power source, a tool cathode, a graphite anode, and an alkaline electrolyte. During machining, the workpiece rotates to form a thin liquid film. The tool cathode approaches the workpiece and contacts the liquid film, thus triggering an electrolytic reaction. When electrolytic bubbles gradually accumulate to form a complete gas film, electrochemical discharge occurs to remove the workpiece material. The host computer control system controls the XYZ three-axis moving platform for tool setting and machining. The adjustment module 400, such as a speed-regulating motor, can control the rotation speed of the workpiece spindle, thereby controlling the workpiece's immersion rotation speed, or the liquid tank height micro-adjustment mechanism can control the electrolyte tank 200 to make fine adjustments to obtain the required electrolyte film thickness, thereby completing the workpiece machining.

[0072] According to the electrochemical discharge machining process construction system proposed in the embodiments of this application, the target workpiece can be clamped by a workpiece spindle and immersed in the electrolyte in an electrolyte tank. The spindle is rotated by a control module so that a stable electrolyte film is attached to the surface of the target workpiece when it is pulled out of the electrolyte. Electrochemical discharge machining is performed on the target workpiece based on the electrolyte film. The spindle speed or the relative distance between the target workpiece and the electrolyte surface is adjusted by an adjustment module to adjust the electrolyte film thickness. The electrolyte film thickness and the electrochemical discharge spark state at each electrolyte film thickness are detected by a detection module. By combining the thickness change law between electrolyte film thickness and speed or relative distance, and the discharge change law between electrolyte film thickness and electrochemical discharge spark state, a corresponding electrochemical discharge machining process for rotating workpieces is constructed. This process is suitable for rotating workpieces and forms a process with a large liquid film thickness adjustment range and simple quantitative control to generate a liquid film at a given electrode immersion depth. This solves the technical problems in related technologies, such as limited applicability, conflict between the processing process of visual measurement method and actual process requirements, making it difficult to carry out the processing continuously, difficulty in forming a stable electrolyte film on the workpiece surface by the fixed height partition method, and difficulty in accurately controlling the thickness of the liquid film on the workpiece surface by the laminar flow flushing method.

[0073] Next, with reference to the accompanying drawings, a method for constructing an electrochemical discharge processing technology according to an embodiment of this application is described.

[0074] Figure 5 This is a flowchart of the construction method of the electrochemical discharge processing technology according to an embodiment of this application.

[0075] like Figure 5 As shown, the method for constructing this electrochemical discharge processing technology includes the following steps:

[0076] In step S501, the target workpiece is clamped on the workpiece spindle so that the target workpiece is immersed in the electrolyte contained in the electrolyte tank.

[0077] In step S502, the workpiece spindle is controlled to rotate at the target speed so that when the surface of the target workpiece is removed from the electrolyte surface, an electrolyte film that meets the first preset stability condition is attached to the surface of the target workpiece.

[0078] In step S503, the rotational speed of the workpiece spindle or the relative distance between the target workpiece and the electrolyte surface is adjusted to detect the electrolyte film thickness on the surface of the target workpiece at different rotational speeds or relative distances.

[0079] In step S504, the thickness of the electrolyte film attached to the surface of the target workpiece is detected, and the electrochemical discharge spark state under each electrolyte film thickness is detected.

[0080] In step S505, the thickness variation law is generated by using the electrolyte film thickness corresponding to each rotation speed or each relative distance, and the discharge variation law is generated by using the electrochemical discharge spark state corresponding to each electrolyte film thickness. The corresponding electrochemical discharge machining process for rotating workpiece is constructed by combining the thickness variation law and the discharge variation law.

[0081] It should be noted that the foregoing explanation of the system embodiment for constructing the electrochemical discharge machining process also applies to the construction method of the electrochemical discharge machining process in this embodiment, and will not be repeated here.

[0082] According to the electrochemical discharge machining process construction method proposed in the embodiments of this application, the target workpiece can be clamped by a workpiece spindle and immersed in the electrolyte in an electrolyte tank. The spindle is rotated by a control module so that a stable electrolyte film is attached to the surface of the target workpiece when it is pulled out of the electrolyte. Electrochemical discharge machining is performed on the target workpiece based on the electrolyte film. The spindle speed or the relative distance between the target workpiece and the electrolyte surface is adjusted by an adjustment module to adjust the electrolyte film thickness. The electrolyte film thickness and the electrochemical discharge spark state at each electrolyte film thickness are detected by a detection module. By combining the thickness change law between electrolyte film thickness and speed or relative distance, and the discharge change law between electrolyte film thickness and electrochemical discharge spark state, a corresponding electrochemical discharge machining process for rotating workpieces is constructed. This process is suitable for rotating workpieces and forms a process with a large liquid film thickness adjustment range and simple quantitative control to generate a liquid film at a given electrode immersion depth. This solves the technical problems in related technologies, such as limited applicability, conflict between the processing process of visual measurement method and actual process requirements, making it difficult to carry out the processing continuously, difficulty in forming a stable electrolyte film on the workpiece surface by the fixed height partition method, and difficulty in accurately controlling the thickness of the liquid film on the workpiece surface by the laminar flow flushing method.
