Technical Field

[0002] In the field of micro-arc oxidation technology, micro-arc oxidation test equipment is used to modify the surface of metal materials. By generating micro-arc discharge on the metal surface, an oxide film layer with special properties is formed. During the test, the temperature of the chemical solution has a significant impact on the effect of micro-arc oxidation. A suitable chemical solution temperature can ensure the stable progress of the micro-arc oxidation reaction and help form a dense oxide film with excellent performance. However, if the chemical solution temperature is too high, it will lead to uneven oxide film growth, loose and porous film layer, and reduced corrosion resistance, wear resistance and other properties of the film layer.

Most existing micro-arc oxidation test devices lack an effective chemical cooling system, or the cooling system has a complex structure, is inconvenient to install and maintain, and occupies a large space, resulting in cumbersome test operations and low efficiency.

[0030] Specifically, as shown in Figure 5 and Figure 8 The support plate 402 is provided with a rotating mechanism 5.

The threaded bolt 602 is installed through the movable slot 601, so that the threaded bolt 602 is fixed to one side of the connecting plate 405, and the threaded bolt 602 is not easily loosened and falls off through the cooperation of the anti-skid pad 603. The position of the placing net 403 is adjusted through the movable slot 601 by rotating the threaded bolt 602, so that the distance between the two placing nets 403 can be adjusted according to the size of the parts, and different sizes of parts can be placed.
[0033] Specifically, as shown in Figure 7 , the limiting mechanism 7 is installed on the support plate 402, the limiting mechanism 7 includes a rotating rod 702, and the rotating rod 702 is rotatably connected in the support plate 402. The rotating rod 702 extends to the outside of both ends of the support plate 402, and the bottom of the rotating rod 702 is threadedly connected with the inside of the bottom of the fixed plate 401. The rotating rod 702 is installed, so that after the support plate 402 and the fixed plate 401 are slid downward to a certain position, the rotating rod 702 is threadedly fastened with the inside of the fixed plate 401 by rotating the rotating rod 702, so that the support plate 402 and the fixed plate 401 are limited in diameter and cannot slide, and a safety protection function is achieved.
[0034] Specifically, as shown in Figure 4 , Figure 5 , and Figure 7 , a compression spring 703 is connected between the bottom of the support plate 402 and the inside of the fixed plate 401, the bottom of the rotating rod 702 is located on the inside of the top of the compression spring 703, and a rotating knob 701 is installed on the top of the rotating rod 702.

The placing net 403 enters the inside of the sink 211 by pressing the support plate 402 to slide away from the elastic force of the compression spring 703, and the rotating knob 701 is rotated to drive the rotating rod 702, so that the bottom of the rotating rod 702 is threadedly fastened with the inside of the fixed plate 401, the support plate 402 cannot rise, and a limiting function is achieved. The support plate 402 is raised for material taking by reversely rotating the rotating rod 702.
[0035] In use, this invention first connects the power supply 201, chiller 202, and mounting base 1. With the assistance of the water tank 211, a micro-arc oxidation test is performed on the parts. Simultaneously, the assembly of the power supply 201, chiller 202, and the end of the mounting base 1 reduces the overall size of the equipment, making operation more convenient and improving testing efficiency. The outer casing 204 provides shielding protection for the outside of the water tank 211. The four ultrasonic transducers operate at frequencies of 40kHz, 80kHz, 120kHz, and 160kHz. The oscilloscope 203 and ultrasonic transducer 210 work together to break up hydrogen bubbles generated during the micro-arc oxidation process, reducing hydrogen explosions on the workpiece surface and lowering noise. A spectrometer provides clearer observation of the micro-arc process. Ultrasonic waves can alter the arrangement of metal ions in the chemical solution, resulting in a denser micro-arc oxidation film with lower porosity and improved salt spray test time. The installation of copper busbar 207 allows electrodes to be introduced into the water tank 211 for test field operation.

The installation of quartz glass allows for observation of the metallographic structure of the film during the micro-arc oxidation process using a spectrometer. The installation of cooling plate 301 encloses the outside of the water tank 211. The cooperation of guide plate 304 and guide channel 303 allows cooling water from the chiller 202 to enter the guide channel 303 through inlet pipe 305. The cooperation of multiple guide plates 304 achieves the desired cooling effect on the water tank. The external circulation cooling system 211, after heat exchange, sends the cooled water through the outlet pipe 302 into the chiller 202 for refrigeration and recirculation. The installation of the fixing plate 401 facilitates the support plate 402. The connecting shaft 404 enables the installation of the connecting plate 405. The connecting plate 405 connects multiple symmetrical placement nets 403. The placement nets 403 facilitate the placement of parts. The sliding between the support plate 402 and the fixing plate 401 allows multiple placement nets 403 to carry parts into the water tank 211 for micro-arc oxidation testing. After the test, the support plate 402 rises, lifting the placement nets 403, exposing them for easy removal of parts. This makes the operation more convenient and safer. The installation of the rotating rod 702 allows the support plate 402 and the fixed plate 401 to slide down to a certain position. Rotating the rotating rod 702 tightens the bottom of the rod into the internal thread of the fixed plate 401, thus limiting the diameter of the support plate 402 and the fixed plate 401 and preventing them from sliding, providing a safety protection function. The installation of the compression spring 703 provides support and resistance to the support plate 402, allowing it to slide to the top of the fixed plate 401 when there is no external force, separating the net 403 from the water tank 211 for easy loading and unloading.
