Description

Technical Field

[0001] The invention relates to a device and method for quantitatively detecting gas electrolysis products in laser jet electrolysis composite processing, and belongs to the field of laser-electrolysis milling composite processing. Background Art

[0002] Laser jet electrolysis composite machining not only has the advantages of good laser machining localization, high machining accuracy, high surface quality of jet electrolysis machining, and no machining stress, but also has significant coupling synergistic advantages. However, the problem of energy regulation of the laser beam in the electrolyte beam in laser jet electrolysis composite machining remains to be solved. Since the hydrogen produced by cathode hydrogen ion reduction in jet electrolysis machining will enter the jet liquid beam, the laser beam will repeatedly pass through the electrolyte and bubble interface. According to the scattering law and Ludwig Beer's law, the attenuation coefficient of the laser will increase in the electrolyte containing bubbles, which will cause the laser energy on the anode surface to be significantly lower than the laser output energy, and the coupling synergistic effect of laser jet electrolysis composite machining cannot be achieved. In addition, the recast layer caused by high laser pulse energy ablation of the anode workpiece surface will reduce the quality of the machined surface. In order to achieve the coupling synergistic effect of laser jet electrolysis composite machining and ensure the quality of the machined surface, quantitative measurement of the gas produced in jet electrolysis machining is a necessary condition for achieving precise control of laser energy.

[0003] CN108907383A proposes a device for generating and collecting electrolytic gas products, which realizes the generation and collection of electrolytic gas products through an electrolytic processing module, a gas-liquid separation module and a gas collection module. However, it is difficult to achieve quantitative measurement of gas electrolytic products by using a gas collection airbag to collect gas electrolytic products; in jet electrolytic processing, when the current density is 3.05A / cm 2 When the processing time is 180s, the volume of gas generated is about 2-3ml; the trace amount of gas electrolysis products limits the use of gas collection bags; in addition, measuring trace amounts of gas electrolysis products requires airtightness testing of the entire device to effectively ensure the accuracy of the measurement.

[0004] "Electrochimica Acta" Vol. 49, No. 13, 2004, pp. 2085-2095 designed an anode gas collection device for electrolytic processing. The water in the glass container was discharged by the drainage method to collect the gas produced by the anodic oxidation, and the gas volume was read by the scale line on the glass container. However, due to the gravity of the water, the gas pressure in the gas collection device is difficult to control. Too much drainage will cause negative pressure in the device, making the measured gas volume too large; too little drainage will cause the pressure in the device to increase, making the measured gas volume too small. In addition, measuring trace amounts of gas electrolysis products requires the entire device to be airtight to effectively ensure the accuracy of the measurement.

[0005] "Scientific Reports" Vol. 10, No. 1, 2020, Article No. 16797 uses a combination of high-speed imaging and large-scale particle image velocimetry to monitor bubbles in the gap of submerged laser jet electrochemical composite machining in real time; however, high-speed imaging technology is difficult to quantitatively measure trace bubbles flowing at high speed in non-submerged jet electrochemical machining. In addition, the overlap of bubbles along the high-speed imaging direction will result in a smaller measured gas volume.

[0006] In summary, the existing quantitative detection device and method of gas electrolysis products in laser jet electrolysis composite processing have certain limitations. Since the bubbles flow at high speed in jet electrolysis processing, the content is small and mainly concentrated between the cathode and anode during processing, it is difficult to accurately measure using the existing quantitative detection method of gas electrolysis products. Therefore, based on the existing technology, the present invention proposes a quantitative detection device and method of gas electrolysis products in laser jet electrolysis composite processing. Summary of the invention

The cathode nozzle 24 is located at a certain distance from the upper surface of the anode workpiece 22. The electrolyte 21 enters the electrolyte circulation pipeline 25 through the gear pump 7 and is sprayed from the cathode nozzle 24 to reach the anode workpiece 22. The laser beam 12 passes through the gas collecting bottle 10 and the electrolyte 21 sprayed from the cathode nozzle 24 acts on the surface of the anode workpiece 22 together; the anode workpiece 22 and the cathode nozzle 24 are respectively connected to the positive and negative electrodes of the electrolytic power supply 8.

[0012] The manual pressurizing unit includes: a manual pressurizing rod 16 allows air to flow through the second gas interface 17, the third gas interface 20, the left gas collection unit and the air pressure balance unit in sequence through the gas pipeline 19, so that the internal air pressure of the whole device increases; the third gas interface 20 is connected to the third gas interface 20 through the gas pipeline 19, and the third gas interface 20 is connected to the inside of the gas collecting bottle 10 through the second gas hose 11. The manual pressurizing rod 16 and the second gas interface 17 are connected through the gas pipeline 19, and a rotating micro-pressure regulator 18 is arranged between the two, and the rotating micro-pressure regulator 18 is used to micro-adjust the air pressure in the whole device. The second gas interface 17 is sealed and connected to a pressure gauge 15, which is powered by a DC power supply 13 and connected to an oscilloscope 14 to display the gas pressure in the device in real time.

[0013] Furthermore, the measuring range of the first syringe 5 is greater than that of the second syringe 6, and the first syringe 5 and the second syringe 6 are used sequentially for suction; the first syringe 5 can collect most of the gas electrolysis products; the second syringe 6 with an accuracy of 0.01 ml is suctioned after the first syringe 5 to ensure the measurement accuracy.

[0014] A quantitative detection method for gas electrolysis products in laser jet electrolysis composite processing is implemented based on the above-mentioned detection device. The method mainly includes two parts: device airtightness detection and gas electrolysis product quantitative measurement. The measurement accuracy of this method can reach 0.01ml, which meets the measurement requirements of gas electrolysis products in jet electrolysis processing. In the method described, the laser beam 12 is irradiated on the surface of the anode workpiece 22 through the gas collecting bottle 10; in addition, the determination of gas electrolysis products in laser jet electrolysis composite processing can accurately control the laser power, avoiding the problems of low laser jet electrolysis composite processing material removal rate caused by too small laser power and low processing surface quality caused by excessive laser power; it is achieved by the following steps:

[0015] The first step is to test the air tightness of the device;

[0016] Before quantitative detection of gas electrolysis products, it is necessary to conduct air tightness test of the device; seal all connecting pipelines and connect DC power supply 13, wait for the oscilloscope 14 connected to the pressure gauge 15 to show stable readings, and introduce air into the gas collecting bottle 10 through the manual pressure rod 16 and the rotating micro pressure regulator 18 to make the liquid level of the graduated tube 3 in the pressure balance unit greater than the theoretical gas electrolysis yield of 2.5mL; ensure that the output signal of the pressure gauge 15 does not drop continuously during the processing time, otherwise reseal all devices. The theoretical gas electrolysis yield is calculated by Faraday's law.

[0017] The second step is quantitative measurement of gas electrolysis products;

[0018] After the air tightness test of the device is completed, a quantitative measurement experiment of the gas electrolysis product is carried out; the gear pump 7 is turned on to make the electrolyte 21 flow through the electrolyte circulation pipeline 25 and be ejected from the cathode nozzle 24, and the liquid level of the electrolyte 21 in the gas collecting bottle 10 is stable, and the liquid levels on the left and right sides of the U-shaped tube 1 are consistent; the electrolysis power supply 8 is turned on, and after the processing is completed, the electrolysis power supply 8 is turned off and cooled for 15 minutes, and the gas in the gas collecting bottle 10 is sucked in turn by the first syringe 5 and the second syringe 6; finally, the liquid levels on both sides of the U-shaped tube 1 are kept horizontal, and the total volume sucked by the first syringe 5 and the second syringe 6 is recorded as the volume of the gas electrolysis product.

[0019] The beneficial effects of the present invention are:

[0020] The present invention adopts a gas pressure balance unit to avoid the phenomenon that the volume of the measured gas electrolysis product is too small due to the increase in gas pressure caused by gas generation in jet electrolysis processing. The gas collection unit ensures the measurement accuracy of the gas electrolysis product by suction through a high-precision syringe. The device realizes the detection of the airtightness of the entire device by integrating a manual pressurizing unit to avoid experimental errors. The device and method proposed can accurately regulate the laser power in laser jet electrolysis composite processing, avoiding the problems of low material removal rate in laser jet electrolysis composite processing due to too small laser power and reduced processing surface quality due to excessive laser power.

[0030] The manual pressurizing unit includes: a manual pressurizing rod 16 allows air to flow through the second gas interface 17, the gas interface 120, the left gas collection unit and the air pressure balance unit through the gas pipeline 19, so that the internal air pressure of the entire device increases, and a rotating micro-pressure regulator 18 is arranged between the manual pressurizing rod 16 and the second gas interface 20. The second gas interface 17 is sealed and connected to a pressure gauge 15. The pressure gauge 15 is powered by a DC power supply 13 and is connected to an oscilloscope 14 to display the gas pressure in the device in real time.

[0031] The quantitative detection method of gas electrolysis products based on the above device includes the following specific steps:

[0032] The first step is to build the device;

[0033] Before the experiment, an insulating boss 23 is placed in the gas collecting bottle 10 to realize non-immersion electrolyte jet processing, and the electrolyte 21 is introduced into the gas collecting bottle 10 and the liquid level of the electrolyte 21 is lower than the upper surface of the insulating boss 23. The anode workpiece 22 is fixed above the insulating boss 23 and connected to the positive electrode of the electrolytic power supply 8. The cathode nozzle 24 is connected to the negative electrode of the electrolytic power supply 8 and connected to one end of the electrolyte circulation pipeline 25. The gear pump 7 is connected in the middle of the electrolyte circulation pipeline 25, and the other end is immersed below the liquid level of the electrolyte 21 in the gas collecting bottle 10. The bottle mouth of the gas collecting bottle 10 is sealed with a second rubber plug 9 with multiple holes, and the first syringe 5 and the second syringe 6 penetrate into the gas collecting bottle 10 through the holes on the insulating rubber 27. In addition, the gas collecting bottle 10 is connected to the right side of the U-shaped tube 1 through the first gas guide hose 4, and the left side of the U-shaped tube 1 is connected to the graduated tube 3. Both sides of the U-shaped tube 1 are sealed with rubber plugs 2. The gas collecting bottle 10 is connected to the gas interface 120 through the second gas hose 11, and the gas interface 120 is connected to the second gas interface 17, the rotary micro pressure regulator 18 and the manual pressure rod 16 in sequence through the gas pipeline 19. The second gas interface 17 is connected with a pressure gauge 15 to monitor the gas pressure in the device in real time. The pressure gauge 15 is powered by a DC power supply 13 and displays and records the output signal through an oscilloscope 14. The second step is quantitative measurement of gas electrolysis products;

[0034] After the device is built, it is necessary to monitor the air tightness. Air is introduced into the device through the manual pressure rod 16 and the rotating micro pressure regulator 18, and the changes in the liquid level in the graduated tube 3 are observed; when the liquid level in the graduated tube 3 is greater than the theoretical value of the volume of the gas electrolysis product of the jet electrolysis processing, the pressurization is stopped, the output signal of the pressure gauge 15 is recorded in real time, and it is observed whether there is a continuous signal drop in the output signal within the processing time range; if there is, the device needs to be resealed; if the output signal is stable at a certain value for a long time, it proves that the air tightness of the device is good, and the next step of quantitative measurement of the gas electrolysis product can be carried out.

[0035] Figure 2 This is a flow chart for air tightness detection. Before quantitative detection of gas electrolysis products, it is necessary to conduct an air tightness test on the device; seal all connecting pipelines and connect the DC power supply 13. After the reading of the oscilloscope 14 connected to the pressure gauge 15 is stable, air is introduced into the gas collecting bottle 10 through the manual pressurizing rod 16 and the rotating micro-pressure regulator 18 to make the liquid level of the graduated tube 3 in the air pressure balance unit greater than the theoretical gas electrolysis output; ensure that the output signal of the pressure gauge 15 does not drop continuously during the processing time, otherwise reseal all devices.

[0036] The third step is quantitative measurement of gas electrolysis products;

[0037] After the air tightness test of the device, the second gas-conducting hose 11 is closed, and the quantitative measurement of the electrolysis products of the jet electrolysis gas is performed. Turn on the gear pump 7 to allow the electrolyte 21 to flow through the electrolyte circulation pipeline 25 and be ejected from the cathode nozzle 24, until the liquid level of the electrolyte 21 in the gas collecting bottle 10 is stable and the liquid levels on the left and right sides of the U-shaped tube 1 are consistent; turn on the electrolysis power supply 8 to make the electrolysis voltage 30V, adopt a constant pressure processing method, after the 180s processing time is over, first turn off the electrolysis power supply 8 and then turn off the gear pump 7, after cooling for 15 minutes, first use the first syringe 5 to suck the gas electrolysis product in the gas collecting bottle 10, and observe the liquid level of the graduated tube 3 in real time; when the liquid level in the graduated tube 3 is close to the liquid level on the right side of the U-shaped tube 1, stop the suction of the first syringe 5, and use the second syringe 6 with an accuracy of 0.01mL to suck the gas electrolysis product in the gas collecting bottle 10; finally, keep the liquid levels on both sides of the U-shaped tube 1 horizontal, and record the total volume sucked by the first syringe 5 and the second syringe 6 as the volume of the gas electrolysis product.

[0038] Figure 3 This is a diagram of the air tightness test results. In the air tightness test, the output signal of the pressure gauge 15 described in the process does not drop continuously during the processing time, indicating that the constructed quantitative detection device for gas electrolysis products in laser jet electrolysis composite processing has good air tightness.

[0039] Figure 4 : is a flow chart for measuring gas electrolysis products. After the air tightness test of the device is completed, the gas electrolysis products are quantitatively measured; the gear pump 7 is turned on to make the electrolyte 21 flow through the electrolyte circulation pipeline 25 and be ejected from the cathode nozzle 24, and the liquid level of the electrolyte 21 in the gas collecting bottle 10 is stable, and the liquid levels on the left and right sides of the U-shaped tube 1 are consistent; the electrolysis power supply 8 is turned on and the electrolysis power supply 8 is turned off after the processing time is over and cooled for 15 minutes, and the gas in the gas collecting bottle 10 is sucked in turn by the first syringe 5 and the second syringe 6; finally, the liquid levels on both sides of the U-shaped tube 1 are kept horizontal, and the total volume sucked by the first syringe 5 and the second syringe 6 is recorded as the volume of the gas electrolysis products.

[0040] Figure 5 The graph shows the measurement results of gas electrolysis products. The gas electrolysis products generated by jet electrolysis gradually increase during the 180s processing time. After cooling for 15 minutes after the processing, the current density within 180s is 3.05A / cm 2 The volume of the gas electrolysis product produced is 2.51 mL.
