A precisive internal concentric clamp of centering vertical high-frequency brazing die

Abstract

A precisely centered die fixture for concentric vertical HF soldering is composed of a shelf for the workpiece to be soldered, a centered core wire, two wire clamps for fixing both ends of said core wire, the regulating screw for regulating the perpendicularity between reference plane and core wine, etc.

Description

technical field [0001] The invention relates to a mold fixture for brazing, in particular to a mold fixture requiring precision inner alignment and concentric vertical high-frequency brazing. Background technique [0002] When developing the millimeter wave distributed action oscillator, the main part of the oscillator is the cavity, such as figure 1 As shown, the cavity is a coupled cavity chain slow-wave circuit composed of multiple cavity plates superimposed. In the figure, the lower casing 22, the lower cavity body 23, the output cavity piece 24, the transition cavity piece 25, the tuning cavity piece 26, the upper cavity body 27, and the upper tube casing 28 are stacked from bottom to top to form a cavity with a common central axis. , the central holes of each component are located on the central axis, communicate with each other to form the electron injection channel 21. In order to fully exchange energy between the electron beam and the high-frequency field, it is n...

AI Technical Summary

Problems solved by technology

From the anode hole to the electron injection port of the cavity, the non-concentricity is often greater than 0.10mm, so the electron injection pass rate is generally below 50%, which cannot meet the performance requirements of tube making
