Description

[0001] The present application relates to the field of electro - machining, in particular to a conical - pendulum - like magnetic - field generating device and a method for regulating the transport of electrolytic - machining gap products. Background Art

[0002] Mechanical tooth - profile modification methods usually achieve the modification by adjusting the tool shape and motion trajectory on the basis of the original gear manufacturing process. However, mechanical tooth - profile modification is applicable to large - scale conventional full - tooth gears. For micro - sized, non - full - tooth, and highly customized high - strength micro - tooth joints, there are deficiencies such as difficulties in preparing micro - tools, easy interference between tool trajectories and other compact structures of micro - tooth joints, and limitations of the machining process by material hardness.

[0003] Using the method of electrolytic tooth - profile modification can solve the problems of insufficient tool - modification accuracy and the influence of material hardness on the modification result. Electrolytic tooth - profile modification is a non - contact machining method, which has the advantages of high flexibility, no need for complex multi - axis linkage, and is not limited by material hardness and strength. Moreover, electrochemical dissolution can also flatten the anode tooth surface while performing tooth - profile modification. This modification method is suitable for the tooth - profile modification of highly customized micro - tooth joints. However, during the electrolytic - modification process, there will be stray - corrosion phenomena, and the large viscosity of the electrolyte leads to the beam - current phenomenon, which affects the transport of electrolytic products, and further affects the electrolytic - modification accuracy and tooth - surface quality.

[0028] To make the above-mentioned objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the protection scope of the present application.

[0029] It should be noted that in any embodiment of the present invention, during the electrolytic machining process, a conical pendulum-like magnetic field is applied. Based on the calibrated magnetic field model, as well as the conical pendulum-like magnetic field data and physical boundary conditions, the convex optimization problem is solved to obtain the driving current of each electromagnet constituting the conical pendulum-like magnetic field generator, so as to generate the required conical pendulum-like magnetic field at the electrolytic machining gap, realizing the adjustable and controllable conical pendulum-like magnetic field. By changing factors such as the magnetic induction intensity, gradient, magnetic field swing frequency, and the ratio of the magnetic induction intensity in the vertical direction to that in the horizontal direction of the conical pendulum-like magnetic field, the stray corrosion and the homogenization of high-viscosity electrolyte during the electrolytic tooth profile modification process are affected, thereby improving the modification accuracy and tooth surface quality.

[0030] Refer to Figure 1-2, which shows a device for regulating the transport of electrolytic machining gap products using a conical pendulum-like magnetic field according to an embodiment of the present application. The device is used to stir the electrolyte in the electrode gap through a magnetic field, and includes an electrolytic device 4 and a conical pendulum-like magnetic field generator 1; wherein, the conical pendulum-like magnetic field generator 1 includes a plurality of electromagnets 11; the electrolytic cell in the electrolytic device 4 is arranged at the center of the conical pendulum-like magnetic field generator 1, and a plurality of the electromagnets 11 are respectively arranged at corresponding preset positions; when electrolytic machining is carried out, the specific magnetic field generated by the conical pendulum-like magnetic field generator 1 arranged around the electrolytic cell causes the electrolyte in the interelectrode gap and the stray corrosion generated during the electrolytic process to flow along with the magnetic field. In the embodiment of the present application, through a device for regulating the transport of electrolytic machining gap products using a conical pendulum-like magnetic field, the device is used to stir the electrolyte in the electrode gap through a magnetic field, and includes an electrolytic device 4 and a conical pendulum-like magnetic field generator 1; wherein, the conical pendulum-like magnetic field generator 1 includes a plurality of electromagnets 11; the electrolytic cell in the electrolytic device 4 is arranged at the center of the conical pendulum-like magnetic field generator 1, and a plurality of the electromagnets 11 are respectively arranged at corresponding preset positions; when electrolytic machining is carried out, the specific magnetic field generated by the conical pendulum-like magnetic field generator 1 arranged around the electrolytic cell improves the transport uniformity of the electrolyte and electrolytic products in the interelectrode gap and reduces the stray corrosion generated during the electrolytic process. Thereby improving the accuracy of electrolytic dressing and the quality of the machined workpiece surface.

[0031] Next, a device for regulating the transport of electrolytic machining gap products using a conical pendulum-like magnetic field in this exemplary embodiment will be further described.

[0032] In an embodiment of the present invention, the conical pendulum-like magnetic field generator is composed of at least 8 electromagnets.

[0033] It should be noted that the required magnetic field needs to be generated by exciting the magnetic field combination of the electromagnets in the conical pendulum-like magnetic field generator 1. Different directions and intensities of magnetic fields can be generated according to the arrangement of the conical pendulum-like magnetic field generator 1, so that the generated specific magnetic field acts on the electrolytic device 4. Insufficient number of the conical pendulum-like magnetic field generators will result in the inability to generate the target magnetic field, affecting the effect of magnetic field-assisted electrolytic machining.

[0034] In a specific implementation, 8 electromagnets 11 are set as the conical pendulum-like magnetic field generator 1 around the electrolytic device. The electromagnets 11 are provided with coils 12, and current is passed through the coils 12 to excite the electromagnetic field of the electromagnets.

[0035] In an embodiment of the present application, it further includes a current controller. The electromagnet 11 is connected to the current controller for controlling the current of the coil 12 and thus controlling the magnetic field.

[0036] It should be noted that the current of the electromagnet 11 that constitutes the conical pendulum-like magnetic field generator 1 can be regulated by the current controller, so as to control the distribution of the magnetic field generated by the conical pendulum-like magnetic field generator 1. The magnetic fields excited by the electromagnet 11 that constitutes the conical pendulum-like magnetic field generator 1 are superimposed to finally generate the target magnetic field. At the same time, during the electrolysis process, the magnetic field distribution can also be changed at any time according to the actual situation.

[0037] In an embodiment of the present application, it further includes a support frame 2. The support frame 2 makes the iron core end face of the electromagnet 11 enclose a spherical domain, and is used to support and fix the conical pendulum-like magnetic field generator 1; wherein, the material of the support frame 2 is aluminum profile.

[0038] It should be noted that the support frame 2 is used to fix the conical pendulum-like magnetic field generator 1. In order to make the conical pendulum-like magnetic field generator 1 fixed stably and convenient to adjust, a support block 3 is also provided on the support frame 2, which is used to fix the conical pendulum-like magnetic field generator 1 and can adjust the angle of the conical pendulum-like magnetic field generator 1. Both the support frame 2 and the support block 3 are made of non-magnetic aluminum profile material, so as to avoid affecting the magnetic field generated by the conical pendulum-like magnetic field generator 1 or being affected by the magnetic field, which may affect the electrolysis process.

[0039] In an embodiment of the present application, the iron core end face of the electromagnet that constitutes the conical pendulum-like magnetic field generator 1 does not completely cover the spherical surface, leaving an installation space for the electrolysis device.

[0040] It should be noted that the iron core end face of the electromagnet that constitutes the conical pendulum-like magnetic field generator 1 does not completely cover the spherical surface, leaving an installation space for the electrolysis device, and an intervening space can be left, which is convenient for the installation, disassembly and sealing of the electrolysis device 4. Only a simple fixture is needed to place the electrolysis device 4 at the center of the spherical domain, which is convenient for operation.

[0041] In an embodiment of the present application, the electrolysis device 4 includes an electrolytic cell, electrodes and a power supply: wherein, the material of the electrolytic cell is a non-ferromagnetic material.

[0042] It should be noted that the material of the electrolytic cell is set as a non-ferromagnetic material to avoid the electrolytic cell affecting the magnetic field generated by the conical pendulum-like magnetic field generator 1, causing the preset magnetic field direction and intensity to change, and affecting the electrolysis accuracy and electrolysis quality.

[0043] In an embodiment of the present application, an electrolytic solution is injected into the electrolytic cell during electrolysis, and the electrolytic solution is an aqueous solution or an organic electrolyte solution.

[0044] It should be noted that an electrolytic solution can be injected into the electrolytic cell. The electrolytic solution can be an aqueous solution, including acidic, neutral, and alkaline solutions, or an organic electrolytic solution, which can be specifically determined according to the material of the cathode workpiece, the material of the workpiece to be electrolyzed, and the cost.

[0045] Referring to Figure 3 , in an embodiment of the present application, a method for regulating the transport of electrolytic machining gap products by using a conical pendulum-like magnetic field generator is also proposed. The method is implemented by the device described in any one of the above;

[0046] The method includes:

[0047] S110. Calculate the required magnetic field components according to the position of the electrolytic machining gap and the electrode arrangement;

[0048] S120. Set the conical pendulum-like magnetic field generator to generate a target magnetic field that reaches the magnetic field components;

[0049] S130. Perform electrolytic machining on the electrolytic device under the target magnetic field to obtain a machined workpiece.

[0050] Next, a method for regulating the transport of electrolytic machining gap products by using a conical pendulum-like magnetic field in this exemplary embodiment will be further described.

[0051] As described in step S110, calculate the required magnetic field components according to the position of the electrolytic machining gap and the electrode arrangement.

[0052] It should be noted that according to the position of the electrolytic machining gap and the electrode arrangement in the electrolytic device, a magnetic field distribution that can minimize the stray corrosion generated during the electrolysis process is calculated. At the same time, this time-varying magnetic field can also make the viscosity of the electrolytic solution evenly distributed, improve the physical and chemical properties of the area to be machined, and improve the surface quality and accuracy of the workpiece to be machined.

[0053] As described in step S120, set the conical pendulum-like magnetic field generator to generate a target magnetic field that reaches the magnetic field components.

[0054] It should be noted that in this step, by regulating the current of the electromagnet coil that constitutes the conical pendulum-like magnetic field generator, a magnetic field with the expected intensity and direction can be obtained, so that the magnetic field can control the stray corrosion and the uniformization of the viscosity of the electrolytic solution during the electrolysis process.

[0055] As described in step S130, perform electrolytic machining on the electrolytic device under the target magnetic field to obtain a machined workpiece.

[0056] It should be noted that the conical pendulum-like magnetic field-assisted method is different from the hydrodynamic method and is an auxiliary method that can penetrate into the diffusion region on the anode surface.

[0057] In one embodiment of the present application, the magnetic field component generated by the conical pendulum-like magnetic field generator 1 is changed by setting the current of the electromagnet 11.

[0058] It should be noted that by controlling the control current of the conical pendulum-like magnetic field generator, the horizontal rotation component of the target magnetic field alternates on the anode tooth surface. The horizontal rotation component of the conical pendulum-like magnetic field alternates on the anode tooth surface. Under the alternating action of the Lorentz force, the electrolyte flow field in the convective region on the anode surface is homogenized, and the viscosity of the electrolyte is reduced, providing a stable diffusion boundary condition for the anode diffusion region; while the vertical component acts on the anode diffusion region and the diffusion-convection transition region, restricting ions near the cathode to inhibit stray corrosion, achieving the purpose of improving the physical and chemical properties of the processing area and improving the surface quality and the finishing accuracy of the part.

[0059] In one embodiment of the present application, the target magnetic field intensity is 0.2T.

[0060] Although the preferred embodiments of the embodiments of the present application have been described, those skilled in the art can make additional changes and modifications once they learn the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the embodiments of the present application.

[0061] Finally, it should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or terminal device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or terminal device comprising the element.
