Abstract

The invention provides an inductive coupling bar adjusting device and a coaxial cavity radio frequency device. The inductive coupling bar adjusting device comprises an inductive coupling bar, expansion screw rods, cover plate locking screw rods, a cover plate and nuts, wherein the cover plate locking screw rods can be rotatably adjusted and drive the expansion screw rods to expand up and down; and the expansion screw rods drive the inductive coupling bar to expand up and down in a horizontal linear mode so as to adjust the vertical height of the inductive coupling bar. By the inductive coupling bar adjusting device and the coaxial cavity radio frequency device, the vertical height of the inductive coupling bar can be quickly and accurately adjusted, and accurate and reliable data is provided for researching and developing conversion to mass production, so that the requirements on indexes of the product are met to the maximum extent, and the risk of poor production is reduced.

AI Technical Summary

Problems solved by technology

[0011] First, in the prior art, only the middle part of the inductive coupling rod can be moved to make it deform, so as to achieve the purpose of adjusting its height

However, it is very inconvenient to adjust in this way. Since the horizontal direction of the inductive coupling rod is a non-linear rod with a raised or concave middle, the data of the vertical height of the measuring instrument is very unreliable. Therefore, it is necessary to adjust the inductive coupling rod. The vertical height value for cannot be measured precisely

[0012] Second, in the process of product production, the inductive coupling rod is a U-shaped rod that is in a straight line in the horizontal direction. Design choices can be made based on the experience of R&D personnel, which undoubtedly poses a great risk to production
