Description

Technical Field

[0001] The present 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 Art

[0002] Electrochemical discharge machining is an effective method commonly used to process insulating hard and brittle materials (such as quartz glass). Its basic principle is to use an electrolytic circuit to electrolyze and form an air film on the tool electrode. The high temperature and high pressure generated by the instantaneous spark discharge in the insulating air film are combined with physical and chemical effects in the electrolyte to remove the material. Electrochemical discharge occurs in the air film that isolates the tool electrode from the electrolyte. In this process, the depth of immersion (that is, the depth of the tool electrode immersed from the electrolyte surface) has a great influence on the formation of the air film and the discharge state. On the one hand, increasing the immersion depth increases the discharge channel and increases the probability of discharge occurring on the side wall; on the other hand, it increases the difficulty of bubbles generated by electrolysis to form a complete and stable air film on the surface of the tool electrode. Therefore, in the electrochemical discharge process, a given thin immersion depth is required to narrow the discharge channel, so that the discharge is concentrated in a smaller area and the air film is formed quickly.

[0003] In the related art, a micro-immersion depth needs to be given when forming an electrochemical discharge process, wherein the methods for giving a micro-immersion depth mainly include: (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 renewal measure, the high temperature generated by the discharge will cause the electrolyte to evaporate quickly, making it impossible to continue the processing. (2) Fixed-height partition method: It improves the structure of the processing liquid tank, and uses 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 the surface tension of the electrolyte, the electrolyte often cannot form a stable thin layer on the surface of the workpiece, and is easily aggregated into intermittent liquid beads, and cannot form a stable discharge path. (3) Laminar flow method: Use the nozzle to flush liquid to form a thin liquid film on the surface of the workpiece. The thickness of the thin liquid film is adjusted by adjusting the liquid flow, distance, height and other parameters of the nozzle to give a specified immersion depth. There are many factors that affect the thickness of the liquid film in this method, and it is difficult to quantitatively control the thickness of the liquid film. In addition, the above three methods are only applicable to flat workpieces and are difficult to apply when processing rotating workpieces.

[0004] In summary, the scope of application of relevant technologies is limited, and there is a conflict between the processing process of the visual measurement method and the actual process requirements, which makes it difficult to continue the processing 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, which urgently needs to be improved.

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

[0026] The following describes the construction system and method of the electrochemical discharge machining process of the embodiment of the present application with reference to the accompanying drawings. In view of the technical problems such as the limited scope of application of the related technologies mentioned in the above background technology, the conflict between the machining process of the visual measurement method and the actual process requirements, which makes it difficult to continue the machining process, the difficulty in forming a stable electrolyte film on the surface of the workpiece by the fixed height partition method, and the difficulty in accurately controlling the thickness of the liquid film on the surface of the workpiece by the laminar flow flushing method, the present application provides a construction system for an electrochemical discharge machining process, in which a workpiece spindle can be used to clamp the target workpiece, and the target workpiece can be immersed in the electrolyte of the electrolyte tank, and the workpiece spindle can be controlled to rotate by a control module, so that during the machining process of the target workpiece, a stable layer of electrolyte is attached to the surface of the target workpiece when it is withdrawn from the electrolyte surface. The electrolyte film is formed, and the target workpiece is electrochemically discharged based on the electrolyte model. The rotation speed of the workpiece spindle or the relative distance between the target workpiece and the electrolyte surface is adjusted by the adjustment module to adjust the thickness of the electrolyte film. The detection module is then used to detect the electrolyte film thickness and the electrochemical discharge spark state under each electrolyte film thickness. The corresponding electrochemical discharge machining rotary workpiece process is constructed by combining the thickness variation law between the electrolyte film thickness and the rotation speed or relative distance, and the discharge variation law between the electrolyte film thickness and the electrochemical discharge spark state. It is suitable for rotating workpieces and forms a process for generating a given electrode immersion depth of the liquid film with a large liquid film thickness adjustment range and simple quantitative control. Therefore, the technical problems in the related technology such as limited scope of application, conflict between the processing process of the visual measurement method and the actual process requirements, making it difficult to continue the processing process, difficulty in forming a stable electrolyte film on the workpiece surface by the fixed height partition method, and difficulty in accurately controlling the liquid film thickness on the workpiece surface by the laminar flushing method are solved.

[0027] Specifically, Figure 1 A schematic diagram of the structure of a system for constructing an electrochemical discharge machining process provided in an embodiment of the present 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 a target workpiece.

[0030] In actual implementation, the workpiece spindle 100 may be used to clamp the target workpiece, wherein the target workpiece is a rotary workpiece, so that when the workpiece spindle 100 rotates, the target workpiece can be driven by the workpiece spindle 100 to rotate around its own axis.

[0031] In order to ensure that the target workpiece can stably adhere to the electrolyte film in the subsequent process, 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 the present application, the target workpiece is a rotating non-conductive workpiece.

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

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

[0035] The electrolyte tank 200 may be filled with electrolyte so that the target workpiece is partially immersed in the electrolyte. In the subsequent processing, the target workpiece may be rotated to bring out the electrolyte and form an attached electrolyte film.

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

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

[0038] The electrolyte may contain fluorescent dye to facilitate subsequent detection of the thickness of the electrolyte film.

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

[0040] Among them, the inner groove is placed inside the outer groove, and the groove wall height of the inner groove is greater than the groove wall height of the outer groove.

[0041] As a possible implementation method, 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 the present application, the electrochemical discharge machining process construction 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 the 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.

[0044] In some embodiments, a circulating liquid pump may be used to circulate 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] Among them, the second preset stability condition can be set accordingly according to actual conditions such as the workpiece size, the inner groove size, etc., and no specific limitation is made 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, a layer of electrolyte film that meets the first preset stability condition is attached to the surface of the target workpiece when the electrolyte surface is extracted, and electrochemical discharge machining of the target workpiece is performed based on the electrolyte model.

[0047] Furthermore, the embodiment of the present application can use the control module 300 to control the rotation of the workpiece spindle 100, so that the surface of the target workpiece drives a thin and stable electrolyte film when the electrolyte surface is extracted. Therefore, during the machining process, after the target workpiece rotates to form a thin liquid film, the tool cathode approaches the target workpiece and contacts the liquid film to generate an electrolytic reaction. When the electrolytic bubbles gradually accumulate to form a complete air film, electrochemical discharge occurs to erode the workpiece material, thereby completing the electrochemical discharge machining.

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

[0049] It is understandable that different rotation speeds of the workpiece spindle 100 affect the thickness of the electrolyte film brought up by the target workpiece. Similarly, the relative distance between the target workpiece and the electrolyte surface, that is, the depth of the target workpiece immersed in the electrolyte, also affects the thickness of the electrolyte film brought up by the target workpiece.

[0050] In order to understand the thickness variation law of the electrolyte film, the embodiment of the present 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 a pad in the electrolyte tank 200, adjusting the micro-motion platform, etc., 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 the actual implementation process, the embodiment of the present application can detect the thickness of the electrolyte film attached to the surface of the target workpiece at different rotation speeds to establish a variation law between the rotation speed and the electrolyte film thickness;

[0054] Similarly, the embodiment of the present 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 a variation law between the relative distance and the electrolyte film thickness.

[0055] The embodiment of the present application can also detect the influence of different electrolyte film thicknesses on the electrochemical discharge spark state to facilitate subsequent process construction.

[0056] Optionally, in one embodiment of the present 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, and irradiates the planar laser to 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 including fluorescence.

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

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

[0061] For example, the embodiment of the present application can use a continuous solid-state laser as an emitting unit to emit a surface laser, and irradiate the surface laser to 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 means at a later time.

[0062] Specifically, the emitting unit can be arranged in an orthogonal optical path to the capturing unit, wherein the planar laser emitted by the emitting unit irradiates the thin electrolyte film brought up by the workpiece rotation, thereby inducing the fluorescent dye in the electrolyte film to emit fluorescence. The fluorescence is captured by the capturing unit through the filter, and the profile in the thickness direction of the liquid film can be obtained by the image processing means of 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] Construction module 600 is used to generate a thickness variation law using the electrolyte film thickness corresponding to each rotation speed or each relative distance, and to generate 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 rotating workpiece process by combining the thickness variation law and the discharge variation law.

[0064] Furthermore, the construction module 600 can generate a thickness variation law of the electrolyte membrane according to a rotation speed-thickness variation law generated by the electrolyte membrane thickness at different rotation speeds and a distance-thickness law generated by the electrolyte membrane thickness at different relative distances.

[0065] The construction module 600 can also generate a discharge variation rule according to the electrochemical discharge spark state corresponding to different electrolyte film thicknesses.

[0066] By comprehensively analyzing the thickness variation law and the discharge variation law, the embodiments of the present application can clearly define the effects of different settings on the electrolyte film thickness and the effects of different electrolyte film thicknesses on electrochemical machining, so that the established electrochemical discharge machining rotating workpiece process can be adjusted according to the machining requirements of the workpiece to ensure the machining accuracy of the workpiece.

[0067] Combination Figures 2 to 4 As shown, the working principle of the construction system of the electrochemical discharge machining process of the embodiment of the present application is described in detail by taking an embodiment as an example.

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

[0069] Taking a cylindrical rotating quartz workpiece as an example, it includes a small cylindrical end clamped by the clamp of the workpiece spindle clamping mechanism 101 and a large cylindrical end for immersion and rotation. In combination with the embodiments of the present application, the steps of forming a micro-thin liquid film on its surface include: (1) clamping the rotating workpiece on the workpiece spindle 100 so that the axis of the workpiece is in a horizontal position; (2) filling the electrolyte tank 200 with electrolyte so that the lower end of the axis of the workpiece is immersed in the electrolyte, and turning on the circulating liquid pump 700 to circulate the electrolyte in the inner tank 201 and the outer tank 202 of the electrolyte tank 200; (3) rotating the workpiece spindle 100, and using the hydrophilic property of the workpiece to make its surface drive a thin and stable electrolyte film when it is self-rotated and pulled away from the electrolyte surface. Among them, the electrolyte tank 200 can adjust the height through the adjustment module 400, such as the liquid tank height micro-adjustment mechanism, so as to adjust the immersion depth of the cylindrical workpiece.

[0070] like Figure 3As shown, when laser-induced fluorescence is used to detect the thickness of the electrolyte film, a 532nm continuous solid laser (transmitting unit 501), a high-definition digital CCD camera (capturing unit 502), a filter 503, an electrolyte containing rhodamine B fluorescent dye, an oscilloscope, etc. are included. The high-definition digital CCD camera (capturing unit 502) and the continuous solid laser (transmitting unit 501) are arranged in an orthogonal optical path, and the planar laser emitted by the continuous solid laser (transmitting unit 501) irradiates the thin electrolyte film brought up by the rotation of the workpiece, thereby inducing the fluorescent dye in the electrolyte film to emit fluorescence. The fluorescence is captured by the high-definition digital CCD camera (capturing unit 502) through the filter 503, and the contour of the liquid film thickness direction is detected by graying, image segmentation and other image processing methods in the later stage. 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 the embodiment of the present application is applied to an electrochemical discharge machining system to perform workpiece machining, an electrolytic circuit can be formed based on a power supply, a tool cathode, a graphite anode, and an alkaline electrolyte. During the machining process, the workpiece self-rotates to form a thin liquid film, and the tool cathode approaches the workpiece to contact the liquid film so that an electrolytic reaction occurs. When the electrolytic bubbles gradually accumulate to form a complete air film, electrochemical discharge occurs to erode the workpiece material. The host computer control system controls the XYZ three-axis mobile platform for tool setting and mobile machining. The adjustment module 400, such as a speed regulating motor, can control the rotation speed of the workpiece spindle, thereby controlling the immersion rotation speed of the workpiece, or the liquid tank height fine-tuning mechanism can control the electrolyte tank 200 for fine-tuning to obtain the required electrolyte film thickness, thereby completing the workpiece machining.

[0072] According to the construction system of the electrochemical discharge machining process proposed in the embodiment of the present application, the workpiece spindle can be used to clamp the target workpiece, and the target workpiece can be immersed in the electrolyte of the electrolyte tank. The workpiece spindle can be controlled to rotate by the control module, so that during the machining process of the target workpiece, a layer of stable electrolyte film is attached to the surface of the target workpiece when the electrolyte surface is withdrawn, and electrochemical discharge machining of the target workpiece is performed based on the electrolyte model. The rotation speed of the workpiece spindle or the relative distance between the target workpiece and the electrolyte surface is adjusted by the adjustment module to adjust the electrolyte film thickness. The detection module is then used to detect the electrolyte film thickness and the electrochemical discharge spark state under each electrolyte film thickness, so as to construct a corresponding electrochemical discharge machining rotating workpiece process in combination with the thickness variation law between the electrolyte film thickness and the rotation speed or relative distance, and the discharge variation law between the electrolyte film thickness and the electrochemical discharge spark state, so as to be suitable for rotating workpieces, and form a process for generating a given electrode immersion depth of a liquid film with a large liquid film thickness adjustment range and simple quantitative control. As a result, technical problems in related technologies such as limited scope of application, conflict between the visual measurement method's processing and actual process requirements, which makes it difficult to continue the processing process, 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 flushing method were solved.

[0073] Next, a method for constructing an electrochemical discharge machining process according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0074] Figure 5 It is a flow chart of a method for constructing an electrochemical discharge machining process according to an embodiment of the present application.

[0075] like Figure 5 As shown, the construction method of the electrochemical discharge machining process includes the following steps:

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

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

[0078] In step S503, the rotation 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 rotation speeds or different 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 using the electrolyte film thickness corresponding to each rotation speed or each relative distance, and the discharge variation law is generated using the electrochemical discharge spark state corresponding to each electrolyte film thickness, so as to construct the corresponding electrochemical discharge machining rotating workpiece process by combining the thickness variation law and the discharge variation law.

[0081] It should be noted that the above explanation of the embodiment of the system for constructing the electrochemical discharge machining process is also applicable to the method for constructing the electrochemical discharge machining process of this embodiment, which will not be repeated here.

[0082] According to the construction method of the electrochemical discharge machining process proposed in the embodiment of the present application, the target workpiece can be clamped by a workpiece spindle, and the target workpiece can be immersed in the electrolyte of the electrolyte tank. The workpiece spindle can be controlled to rotate by a control module, so that during the machining process of the target workpiece, a layer of stable electrolyte film is attached to the surface of the target workpiece when the electrolyte surface is withdrawn, and electrochemical discharge machining of the target workpiece is performed based on the electrolyte model. The rotation speed of the workpiece spindle or the relative distance between the target workpiece and the electrolyte surface is adjusted by an adjustment module to adjust the thickness of the electrolyte film. The detection module is then used to detect the electrolyte film thickness and the electrochemical discharge spark state under each electrolyte film thickness, so as to construct a corresponding electrochemical discharge machining rotating workpiece process in combination with the thickness variation law between the electrolyte film thickness and the rotation speed or the relative distance, and the discharge variation law between the electrolyte film thickness and the electrochemical discharge spark state, so as to be suitable for rotating workpieces, and form a process for generating a given electrode immersion depth of a liquid film with a large liquid film thickness adjustment range and simple quantitative control. As a result, technical problems in related technologies such as limited scope of application, conflict between the visual measurement method's processing and actual process requirements, which makes it difficult to continue the processing process, 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 flushing method were solved.

[0083] Figure 6 A schematic diagram of the structure of an electronic device provided in an embodiment of the present application. The electronic device may include:

[0084] A memory 601 , a processor 602 , and a computer program stored in the memory 601 and executable on the processor 602 .

[0085] When the processor 602 executes the program, the method for constructing the electrochemical discharge machining process provided in the above embodiment is implemented.

[0086] Furthermore, the electronic device further comprises:

[0087] The communication interface 603 is used for communication between the memory 601 and the processor 602 .

[0088] The memory 601 is used to store computer programs that can be executed on the processor 602 .

[0089] The memory 601 may include a high-speed RAM memory, and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory.

[0090] If the memory 601, the processor 602 and the communication interface 603 are implemented independently, the communication interface 603, the memory 601 and the processor 602 can be connected to each other through a bus and communicate with each other. The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component (PCI) bus or an Extended Industry Standard Architecture (EISA) bus. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 6 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0091] Optionally, in a specific implementation, if the memory 601, the processor 602 and the communication interface 603 are integrated on a chip, the memory 601, the processor 602 and the communication interface 603 can communicate with each other through an internal interface.
