Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a comprehensive testing device for plasma power sources. Background Technology

[0002] A plasma power supply is an electrical device that generates plasma through high-frequency inversion. It is widely used in cutting, welding, surface treatment, and environmental protection. Its core principle is to use a high-voltage electric or magnetic field to ionize the working gas (such as nitrogen or argon), forming a high-temperature, high-energy-density plasma, thereby enabling the processing of materials or the decomposition of gaseous pollutants. The power supply typically consists of a controller, power amplifier, gas supply system, and discharge device. It features a wide-range adjustable resonant frequency (e.g., 20kHz) and high output voltage (0-12kV), and is equipped with a comprehensive protection system to ensure safety.

[0003] In the plasma power supply smoke test, the end of the plasma power supply is placed above the smoke generator, and a transparent cover is placed over the end of the plasma power supply. After passing through the smoke generator, the smoke overflows into the transparent cover, and the dissipation of the smoke inside the transparent cover is observed, thus conducting a smoke test on the plasma power supply. During this process, when the transparent cover is manually placed on and removed from the end of the plasma power supply, the end of the plasma power supply cannot be guaranteed to be placed in the same position for each test. The relative position of the transparent cover and the end of the plasma power supply is not fixed, which increases the variables during the test and affects the test results to some extent.

[0004] Therefore, it is necessary to provide a new integrated testing device for plasma power sources to solve the above-mentioned technical problems. Utility Model Content

A transparent cover 8 is mounted on the support frame 7 via two lifting devices. The transparent cover 8 can be lowered to press against the mounting base 5. The end clamping device is located inside the transparent cover 8. Smoke is generated by the smoke generator 3. The smoke is discharged through the smoke outlet 4 into the through hole 6 and enters the transparent cover 8. The dissipation of the smoke is observed, thereby testing the defogging effect of the plasma power supply. This application can achieve the clamping of the plasma power supply end through the end clamping device, which is convenient for subsequent defogging tests. In addition, the end clamping device can make the plasma power supply end located directly above the smoke outlet 4 during the test, which is convenient for the test work.

[0024] The end clamping device includes a mounting ring 9, a threaded ring 10, a collar 12, multiple first movable inclined blocks 11, and multiple movable components. The threaded ring 10 and the collar 12 are both sleeved on the mounting ring 9, with the threaded ring 10 threadedly connected to the mounting ring 9. The collar 12 is rotatably connected to the threaded ring 10. A guide block 24 is fixed inside the collar 12 and slidably disposed within a groove on the outer wall of the mounting ring 9. Multiple first movable inclined blocks 11 are fixed on the collar 12. Multiple movable components pass through the mounting ring 9 and are respectively positioned corresponding to multiple first movable inclined blocks 11. Each movable component includes a second movable inclined block 13, a top plate 14, and a spring 15. The second movable inclined block 13 movably passes through... Mounting ring 9, the inclined surface of the second moving inclined block 13 is in contact with the inclined surface of the first moving inclined block 11, the top plate 14 is fixed on the second moving inclined block 13, the two ends of the spring 15 are respectively fixed on the top plate 14 and the inner wall of mounting ring 9, rotating mounting ring 9 so that mounting ring 9 is threadedly connected to docking ring 16, placing the plasma power supply end between multiple second moving inclined blocks 13, rotating threaded ring 10, since collar 12 is limited by guide block 24, the threaded ring 10 drives collar 12 and the first moving inclined block 11 on it to move down, so that the second moving inclined block 13 is squeezed to move inward to the mounting ring 9, multiple second moving inclined blocks 13 abut against the plasma power supply end, realizing the clamping operation of plasma power supply;

[0025] The top of the mounting base 5 is fixed with a docking ring 16. The outer wall of the docking ring 16 is threadedly connected to the inner wall of the mounting ring 9. The mounting ring 9 is easy to detach from the docking ring 16 by means of the threaded connection between the outer wall of the docking ring 16 and the inner wall of the mounting ring 9.

[0026] The lifting device includes an electric cylinder 17, a guide rod 18, and a connecting plate 19. The top of the electric cylinder 17 is fixed to the support frame 7, and the telescopic end of the electric cylinder 17 is fixedly connected to the connecting plate 19. One end of the connecting plate 19 is fixed to the transparent cover 8. The guide rod 18 is fixed to the connecting plate 19 and moves through the support frame 7. The electric cylinder 17 drives the connecting plate 19 to move downward, so that the transparent cover 8 can cover the clamping device. The guide rod 18 makes the downward movement of the transparent cover 8 by the connecting plate 19 more stable.

[0027] The top of the transparent cover 8 is fixedly connected to the bellows pipe 20.

[0029] The working principle of this utility model is as follows: A plasma power supply is placed in the plasma power supply placement area 23. The voltage tester 22 is electrically connected to the plasma power supply. The end of the plasma power supply is inserted into the placement groove 25, so that the end of the plasma power supply is located at the through hole 6. The mounting ring 9 is rotated, so that the mounting ring 9 is threaded onto the mating ring 16. The end of the plasma power supply is placed between multiple second moving inclined blocks 13. The threaded ring 10 is rotated. Because the collar 12 is limited by the guide block 24, the threaded ring 10 drives the collar 12 and the first moving inclined block 11 on it to move downwards, causing the second moving inclined block 13 to be squeezed and move inwards towards the mounting ring 9. Multiple second moving inclined blocks 13 press against the end of the plasma power supply to clamp the plasma power supply. The connecting plate 19 is moved down by the electric cylinder 17 so that the transparent cover 8 can cover the clamping device. Smoke is generated by the smoke generator 3. The smoke is discharged through the smoke outlet 4 into the through hole 6 and enters the transparent cover 8. After passing through the transparent cover 8, it enters the bellows tube 20 and overflows from the bellows tube 20. The dissipation of the smoke is observed, thereby testing the defogging effect of the plasma power supply. When the plasma power supply is defogging, the voltage of the plasma power supply during defogging can be viewed by the voltage tester 22 to achieve the purpose of comprehensive testing of the plasma power supply.
