The workpiece does not need to be re-clamped to connect different machining processes, reducing the downtime for part replacement and positioning calibration time, and improving production efficiency.

[0023] The following combination Figures 1-4 The technical solution provided by the present invention is described in more detail.

[0024] Embodiment 1: See also Figures 1-4 The double-liquid tank type electric discharge, electrolysis and ultrasonic composite machining machine provided by the present invention includes a machine body 1, a workbench 2, a base 3, a first machining liquid tank 4 and a second machining liquid tank 5, wherein: the workbench 2 is fixed on the machine body 1 for fixing a workpiece; the machine body 1 is provided with an electric discharge machining head 11 and an electrolytic machining head 12 for machining the workpiece; the first machining liquid tank 4 and the second machining liquid tank 5 are arranged on the base 3 to be reciprocating in both horizontal and vertical directions, and when the first machining liquid tank 4 and the second machining liquid tank 5 are horizontally moved to the machining position and vertically raised and lowered, the workbench 2 can be extended therein; when the workbench 2 is extended into the first machining liquid tank 4 or the second machining liquid tank 5, the workbench 2 serves as the bottom of the first machining liquid tank 4 or the second machining liquid tank 5 to enclose a machining tank structure, and the machining tank structure can retain electrolyte or electric discharge machining fluid that can completely immerse the workpiece.

[0025] Among them, see Figure 4As shown, the “processing tank structure” refers to a structure formed by the cooperation of the first processing liquid tank 4 and the workbench 2 , or a structure formed by the cooperation of the second processing liquid tank 5 and the workbench 2 .

[0026] See also Figure 1 、 Figure 2 and Figure 4 As shown, the machine body 1 is constructed of high-strength cast iron or welded steel, providing the rigidity and vibration resistance required for high-precision machining. The worktable 2 is used for single-stage clamping and precise positioning of the workpiece throughout the entire complex machining process. The workpiece is securely secured to the worktable 2 via a clamp, fixture, or other positioning device. It will be appreciated that the workpiece's position relative to the machine bed remains constant throughout all subsequent machining steps, thus providing a stable machining reference.

[0027] As an alternative embodiment, see Figure 1 As shown, the double-liquid tank type electric spark electrolysis ultrasonic composite machining machine also includes a movable table 9, which is slidably connected to the base 3 and is movable along the X-axis direction; all external liquid tanks 6 are slidably connected to the movable table 9, and the external liquid tanks 6 are movable along the Y-axis direction.

[0028] See also Figure 1 A linear guide rail is provided on the base 3 along the horizontal X-axis direction, and a movable table 9 is installed on the linear guide rail. The movable table 9 can be driven by a servo motor via precision transmission components such as a ball screw to achieve fast, smooth and precisely positioned reciprocating motion along the X-direction.

[0029] The above structure can realize the rapid switching of the first machining fluid tank 4 and the second machining fluid tank 5 between the machining position and the position to be machined. The workbench 2 is fixed and can realize the dual processes of electrolytic machining and electric spark machining on one machine tool.

[0030] In this embodiment, see Figure 1 As shown, at least two mutually independent processing liquid tanks are arranged side by side on the upper surface of the movable platform 9 , specifically a first processing liquid tank 4 and a second processing liquid tank 5 .

[0031] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the first processing liquid tank 4 and the second processing liquid tank 5 have the same structure and both include a tank body 40. The bottom and the top of the tank body 40 are both open sides 41. When the tank body 40 is raised or lowered, the workbench 2 can extend into the corresponding tank body 40 from the open side 41.

[0032] See also Figure 1 and Figure 2As shown, the first and second machining fluid tanks 4 and 5 are characterized by their open bottoms and tops 41, forming a bottomless, topless, frame-like or cylindrical structure. The first machining fluid tank 4 is used to subsequently form a processing space for the EDM fluid and is typically made of metal with a good insulating lining. The second machining fluid tank 5 is used to form a processing space for the electrolytic machining fluid and must be made of a material that is resistant to corrosion from the electrolyte, such as stainless steel or engineering plastics with an anti-corrosion coating.

[0033] The structures of the first processing liquid tank 4 and the second processing liquid tank 5 facilitate the workbench 2 to extend into the tank body 40 from the open side 41 during the lifting and lowering of the corresponding tank body 40, forming a processing tank structure to facilitate the accommodation of the corresponding processing liquid.

[0034] As an alternative embodiment, see Figure 1 and Figure 2 As shown, a through groove 42 is provided on the side of the trough body 40 facing the fuselage 1. The through groove 42 is connected to the trough body 40 and passes through the upper and lower ends of the trough body 40; the workbench 2 includes a table body 21 and a connecting portion 22. The connecting portion 22 is fixedly connected to the table body 21 and the fuselage 1. The table body 21 can extend into the trough body 40 from the open side 41. When the table body 21 is located in the trough body 40 as the bottom of the corresponding trough body 40, the connecting portion 22 passes through the through groove 42.

[0035] When the first processing liquid tank 4 or the second processing liquid tank 5 moves to the bottom of the workbench 2, the first processing liquid tank 4 and the second processing liquid tank 5 are lifted and lowered in the vertical direction, and the workbench 2 enters the tank body 40 from the open side 41. When the workbench 2 is located in the tank body 40, see Figure 4 As shown, the platform 21 can extend into the slot 40 from the open side 41 , and the connecting portion 22 passes through the through slot 42 .

[0036] The matching structure of the above-mentioned trough body 40 and the workbench 2 can realize the rapid assembly of the trough body 40 and the workbench 2. During this process, the workbench 2 fixes the workpiece and remains motionless. The trough body 40 of the first processing liquid trough 4 or the second processing liquid trough 5 is raised or lowered horizontally or vertically to realize the switching of different processes and the assembly of the trough body 40 and the workbench 2, thereby improving the processing efficiency. There is no need to switch the workpiece back and forth, ensuring that the benchmark of the processing technology remains unchanged.

[0037] As an optional embodiment, combined with Figure 2 and Figure 3 As shown, sliders 43 are provided on opposite sides of the through slot 42 , a vertical slide rail 13 is provided on the body 1 , and the sliders 43 are slidably connected to the vertical slide rail 13 .

[0038] When the workbench 2 is inserted into the trough body 40 , the trough body 40 is vertically lifted and lowered accordingly. At this time, the trough body 40 and the fuselage 1 are slidably connected through the slider 43 and the vertical slide rail 13 , so that the position of the workpiece in the trough body 40 can be adjusted.

[0039] As an alternative embodiment, see Figure 1 and Figure 2 、 Figure 4 As shown, an external liquid tank 6 is provided below the first machining liquid tank 4 and the second machining liquid tank 5, and the external liquid tank 6 moves synchronously with the first machining liquid tank 4 or the second machining liquid tank 5 in the horizontal direction; a first liquid outlet pipe 71 for providing electrolyte and a second liquid outlet pipe 75 for providing electrospark machining fluid are provided on the fuselage 1, and the liquid outlet of the first liquid outlet pipe 71 and the liquid outlet of the second liquid outlet pipe 75 are both located above the workbench 2; fluid channels are provided between the workbench 2 and the first machining liquid tank 4, and between the workbench 2 and the second machining liquid tank 5; the external liquid tank 6 is used to receive the electrolyte or electrospark machining fluid flowing down from the corresponding machining tank structure.

[0040] In this embodiment, the function of the external liquid tank 6 is to provide support and to accommodate the processing fluid flowing down from the first processing fluid tank 4 or the second processing fluid tank 5; wherein, a fluid channel is provided between the workbench 2 and the first processing fluid tank 4 and between the workbench 2 and the second processing fluid tank 5, and the fluid channel can be a gap between the workbench 2 and the corresponding tank body 40, or a pore on the workbench 2.

[0041] With this arrangement, the machining fluid in the machining tank structure (the structure formed by the first machining fluid tank 4 and the workbench 2, or the structure formed by the second machining fluid tank 5 and the workbench 2) flows down from the fluid channel and falls into the corresponding external liquid tank 6, and the electrolyte or electrospark machining fluid flowing out of the first liquid outlet pipe 71 or the second liquid outlet pipe 75 falls into the machining tank structure, thereby realizing the replenishment of the machining fluid.

[0042] In order to further form a complete circulation path for the machining fluid, see Figure 1 As shown, as an optional embodiment, the dual-liquid tank type EDM electrolysis ultrasonic composite machining machine also includes an electrolyte storage box 72, an EDM fluid storage box 76, a first pump body 73, a first return pipe 74, a second pump body 77 and a second return pipe 78, wherein: the first liquid outlet pipe 71 and the first return pipe 74 are both connected to the electrolyte storage box 72, and form an electrolyte circulation channel, and the first pump body 73 is located on the electrolyte circulation channel; the outer liquid tank 6 below the first machining fluid tank 4 is connected to the first return pipe 74; the second liquid outlet pipe 75 and the second return pipe 78 are both connected to the EDM fluid storage box 76, and form an EDM fluid circulation channel, and the second pump body 77 is located on the EDM fluid circulation channel; the outer liquid tank 6 below the second machining fluid tank 5 is connected to the second return pipe 78.

[0043] Start the first pump body 73, and the electrolyte falls into the processing tank structure (the structure formed by the first processing liquid tank 4 and the workbench 2, or the structure formed by the second processing liquid tank 5 and the workbench 2) from the electrolyte storage box 72 and the first liquid outlet pipe 71 in turn. The electrolyte falls from the fluid channel between the workbench and the first processing liquid tank 4 to the corresponding external liquid tank 6, and the stored liquid in the external liquid tank 6 flows back to the electrolyte storage box 72 from the first return pipe 74, thereby realizing the circulation of the electrolyte.

[0044] When the second pump body 77 is started, the EDM fluid falls into the machining tank structure (the structure formed by the second machining fluid tank 5 and the workbench 2, or the structure formed by the second machining fluid tank 5 and the workbench 2) from the EDM fluid storage tank 76 and the second liquid outlet pipe 75 in sequence. The EDM fluid falls from the fluid channel between the workbench and the second machining fluid tank 5 to the corresponding external liquid tank 6. The stored liquid in the external liquid tank 6 flows back to the EDM fluid storage tank 76 from the second return pipe 78, thereby realizing the circulation of the EDM fluid.

[0045] The working fluid can be kept in the first processing tank or the second processing tank by controlling the flow rate difference between the upper liquid and the seepage liquid, and the processing fluid can completely immerse the workpiece.

[0046] Machining with circulating electrolyte or EDM fluid and completely immersing the workpiece in the fluid has the following beneficial effects: First, it can maintain a stable processing environment and consistent medium properties: immersion ensures that the processing area (especially the narrow discharge / electrolysis gap) is always filled with processing fluid, avoiding the medium properties (violent fluctuations) caused by insufficient liquid supply or gas-liquid mixing in local areas. Secondly, stable medium properties directly lead to more stable discharge (breakdown voltage, discharge energy, deionization) and electrolysis (current efficiency, dissolution rate) processes, reducing abnormal discharge (such as arcing, short circuit) and electrolysis unevenness, and improving processing efficiency and consistency. Thirdly, it can ensure excellent cooling effect, and the immersion environment provides a maximized heat exchange area. The working fluid directly surrounds the entire workpiece and electrode, which can efficiently , evenly carry away the high heat generated by discharge, Joule heat generated by electrolysis, and heat generated by ultrasonic cavitation. Effectively prevent local overheating, deformation, annealing or burning of the workpiece and electrode. And through the circulation of the machining fluid, the heat dissipation and cooling effects can be further improved. Thirdly, the flowing working fluid (usually in conjunction with a circulating filtration system) can form a continuous flushing flow in the entire machining area. Combined with the strong cavitation effect and micro-jets generated by ultrasonic vibration, the immersion environment can extremely effectively flush, stir and suspend small molten metal particles (etched materials) produced by spark erosion, metal ions produced by electrolytic dissolution, hydroxide precipitates, gases and other reaction products from the narrow machining gap.

[0047] In order to realize the assembly and separation of the machining fluid tank and the workbench 2, the machine tool of this embodiment also includes a lifting drive component. Figure 1 and Figure 2 As shown, as an optional embodiment, a telescopic push rod 8 is provided on the outer liquid tank 6, and the telescopic push rod 8 is vertically arranged. The telescopic end of the telescopic push rod 8 is fixedly connected to the corresponding first processing liquid tank 4 and the second processing liquid tank 5, and is used to drive the first processing liquid tank 4 and the second processing liquid tank 5 to rise and fall in the vertical direction.

[0048] The telescopic push rod 8, such as a pneumatic cylinder, hydraulic cylinder, or electric push rod, has one end fixedly connected to the outer liquid tank 6, and the telescopic end supports the corresponding first processing liquid tank 4 and second processing liquid tank 5. By controlling the extension and retraction of the telescopic push rod 8, the first processing liquid tank 4 or the second processing liquid tank 5 can be driven to move up and down in the vertical direction accurately.

[0049] As an optional embodiment, a rotating table 10 is provided on the fuselage 1, and the electric discharge machining head 11 and the electrolytic machining head 12 are fixed on the rotating table 10. The rotating table 10 is rotatable in the horizontal direction, so that the electric discharge machining head 11 or the electrolytic machining head 12 is moved above the workbench 2.

[0050] By controlling the rotary table 10 to rotate horizontally, either the EDM head 11 or the ECM head 12 can be quickly and accurately switched to a machining position above the workbench 2. The rotary table 10 can be driven by a motor, which will not be described in detail here.

[0051] Through the technical solution of this embodiment, the workpiece does not need to be clamped twice throughout the entire process, ensuring a constant processing reference and extremely high positioning accuracy; at the same time, by switching the physically isolated liquid tank and liquid circulation pipeline, processing fluid contamination is avoided, ensuring the process stability of each process, thereby significantly improving processing efficiency and product quality.

[0052] When switching from EDM to ECM, a servo motor or stepper motor drives the rotary table 10 to precisely rotate the corresponding angle. This rotation accurately moves the second machining fluid tank 5, previously in the non-machining area, directly below the worktable 2, to the machining position. Simultaneously, the first machining fluid tank 4, previously in the machining position, is relocated to the non-machining area.

[0053] Example 2: The present embodiment provides a dual-liquid tank type electric spark electrolysis ultrasonic composite machining method, including the dual-liquid tank type electric spark electrolysis ultrasonic composite machining machine tool of Example 1, the method comprising: fixing the workpiece on the workbench 2; horizontally moving the first machining liquid tank 4 or the second machining liquid tank 5 required to be used to the bottom of the workbench 2, and vertically raising and lowering the first machining liquid tank 4 or the second machining liquid tank 5 until the workbench 2 extends into the first machining liquid tank 4 and surrounds a machining tank structure; retaining an electrolyte or electric spark machining fluid in the machining tank structure that completely immerses the workpiece; and using the electrolytic machining head 12 or the electric spark machining head 11 to electrolytically machine or electrospark machine the workpiece in the workbench 2.
