Description

Technical Field

[0001] This utility model relates to the field of gas flow regulation technology, and specifically to an argon gas flow regulation device. Background Technology

[0002] During the processing of diamond crystal workpieces, their surfaces often retain processing marks, microcracks, and a certain degree of roughness. These defects not only affect the appearance quality of the diamond crystal workpieces but also negatively impact their performance. In material surface treatment, argon gas cluster ion source polishing technology, as an emerging surface treatment method, has many superior performance advantages, bringing a new opportunity to solve the problem of polishing the surface of diamond crystal workpieces. Argon gas flow regulation devices play a very important role in this technology. However, existing argon gas flow regulation devices have many shortcomings in structural design and performance, which can easily lead to problems such as uneven polishing and low efficiency during the polishing process.

[0003] According to the public announcement (CN221881161U), a gas flow rate regulating device in a natural gas transmission equipment is disclosed. This technology discloses that "by rotating a knob, bevel gear one is rotated, which in turn drives bevel gear two to drive the transmission shaft and bevel gear three to rotate, thereby driving bevel gear four to drive screw one to rotate. Multiple support blocks move simultaneously to fit tightly against the inside of the gas transmission pipeline, thereby supporting the inside of the gas transmission pipeline, preventing the gas transmission pipeline from deflecting or loosening, and improving the impact resistance of the pipeline joint. By rotating a handwheel, bevel gear five is rotated, which in turn drives bevel gear six to drive screw two to rotate, thereby causing the sealing block to move left and right under the limit of the limit rod and the drive of the threaded sleeve, thereby adjusting the distance between the sealing block and the regulating plate, so that the gas flow passes through the regulating hole and the flow restriction of the sealing block and the rectification of the rectifier plate and enters the right gas transmission pipeline, thereby achieving stable regulation of the gas flow rate."

[0004] However, this device only changes the flow rate by turning a knob, which cannot precisely control the argon gas cluster ion beam, resulting in uneven polishing of the workpiece.

[0005] To address the aforementioned problems, this application proposes an argon gas flow regulating device. Utility Model Content

The second adjusting wheel 9 has a larger diameter than the third adjusting wheel 10. The second adjusting wheel 9 meshes with the third adjusting wheel 10. The bottom of the regulator 1 has an air inlet 11, and the side end of the regulator 1 has an air outlet 12. The surface of the control sleeve 3 has several control holes 13. By rotating the first adjusting wheel 7, the threaded rod 5 can be driven to move up and down along the adjusting platform 6. The threaded rod 5 drives the slide rod 4, which in turn drives the sealing plate 2 to move up and down. After the sealing plate 2 moves, the argon flow rate can be adjusted by observing the exposure of several control holes 13 when the control sleeve 3 moves up and down. The higher the control hole 13 is exposed, the greater the argon flow rate. The argon flow rate can be visually obtained by observing the leakage of the scale 16 on the slide rod 4 onto the adjusting platform 6. Alternatively, the second adjusting wheel 9 and the third adjusting wheel 10 can be adjusted step by step as needed to finely change the up and down movement of the control sleeve 3 and achieve more precise argon flow rate adjustment.

[0024] Reference Figure 2A sealing ring 14 is attached to the bottom of the sealing plate 2, and a sliding sealing ring 15 is provided on the inner wall of the adjusting platform 6. By setting the sealing ring 14, leakage can be avoided when the sealing plate 2 is pressed down to close, and gas leakage can be avoided when the sliding rod 4 slides on the inner wall of the adjusting platform 6 using the sliding sealing ring 15.

[0025] Reference Figure 2 The surface of the slide bar 4 is provided with a scale 16. By setting the scale 16, the argon flow rate can be judged according to the scale 16 that is exposed when the slide bar 4 moves up and down, so that the adjustment is more precise.

[0026] Reference Figure 3 The surfaces of the first adjusting wheel 7, the second adjusting wheel 9, and the third adjusting wheel 10 are respectively provided with anti-slip texture 21. By setting the anti-slip texture 21, the device can be adjusted more easily when adjusting the argon flow rate through the first adjusting wheel 7, the second adjusting wheel 9, and the third adjusting wheel 10, thus avoiding slippage.

[0027] Reference Figure 4 A buffer 22 is fixedly provided on the outer wall of the regulator 1. A buffer plug 23 is slidably connected to the inner wall of the buffer 22. A sliding column 24 is provided at the bottom of the buffer plug 23. The surface of the sliding column 24 is slidably connected to the buffer 22. A buffer spring 25 is provided at the bottom of the buffer plug 23. The bottom end of the buffer spring 25 is fixedly connected to the buffer 22. By setting the buffer 22, the device can use the buffer structure to relieve the force when the argon flow rate is adjusted, so that the change of argon flow rate is more stable.

[0028] Working principle:

[0029] The argon flow rate regulating device is first installed via an inlet mounting plate 17, an inlet sealing ring 19, an outlet mounting plate 18, and an outlet sealing ring 20. Initial adjustment can be made by rotating the first adjusting wheel 7. Rotating the first adjusting wheel 7 moves the threaded rod 5 up and down along the adjusting platform 6, which in turn moves the sliding rod 4 and the sealing plate 2 up and down. After the sealing plate 2 moves, the argon flow rate can be adjusted by observing the exposure of several control holes 13 as the control sleeve 3 moves up and down. The higher the position, the more control holes 13 are exposed, resulting in a larger argon flow rate. The argon flow rate can be visually obtained by observing the leakage of the scale 16 on the sliding rod 4 onto the adjusting platform 6. Furthermore, the first adjusting wheel 7 can be rotated at a slower speed by rotating the second adjusting wheel 9 using the toothed ring 8, or the first adjusting wheel 7 can be rotated by rotating the third adjusting wheel 10, which in turn moves the second adjusting wheel 9, allowing for progressively finer adjustments.

[0030] When the argon flow rate is adjusted, the argon flow will fluctuate. At this time, the argon will squeeze the buffer plug 23, and the buffer plug 23 will move along the buffer 22 with the slide column 24. The buffer spring 25 is used to balance the argon pressure and dynamically compensate for the pressure fluctuation caused by the change of argon flow rate, so that the gas output is more stable.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
