Embodiment 1

[0019] A spiral cylindrical grinding processing method, the specific steps of the spiral cylindrical grinding processing method are as follows:

[0020] S1: To fix the helix, the helix is ​​tightly wound on the round shaft, and the interval between each turn of the wound helix needs to be kept the same. At the same time, the ends of the helix and the round shaft need to be clamped and connected by clamps, and When the helical wire is wound on the round shaft, it is necessary to wrap a layer of tin foil tightly on the round shaft first, and then the helical wire is wound on the tin foil;

[0021] S2: Test the cylindrical grinder, test the outer edge grinder, adjust the accuracy, and use diamond pen to dress the grinding wheel;

[0022] S3: The circular shaft and the helical wire are integrated as a workpiece and installed on the track of the cylindrical grinding machine to perform surface grinding;

Abstract

The invention discloses a grinding method for an excircle of a helical line. The grinding method for the excircle of the helical line comprises the specific steps: S1, fixing the helical line; S2, testing an excircle grinder; S3, mounting a circular shaft and the helical line integrally as a workpiece on a track of the excircle grinder; S4, setting the rotation number of the integrated circular shaft and the helical line workpiece at 20r / m; S5, rough grinding; S6, primary finish grinding; S7, secondary finish grinding; S8, treatment after grinding; and S9, oil seal storage of the helical line. By way of fixing the helical line and the circular shaft integrally as the workpiece, a tinfoil is also arranged between the helical line and the circular shaft to separate to avoid adhesion under a pressure action of the helical line and the circular shaft. Meanwhile, as the workpiece, the workpiece can be roughly and finely ground under the action of the excircle grinder to achieve grinding of the helical line, so that the processing effect is better.

Description

technical field [0001] The invention relates to the technical field of helical wire processing, in particular to a helical wire cylindrical grinding processing method. Background technique [0002] In the microwave field, traveling wave tubes are the best combination of bandwidth and gain, among which helical traveling wave tubes are the most widely used. The high-frequency circuit of the helical TWT is generally a helical metal wire or metal strip, which is clamped by three or more dielectric rods and fixed in the metal tube shell. The basic role of the helical wire is to provide a high-frequency electromagnetic wave with an axial propagation speed close to the electron motion speed and a sufficiently strong axial electric field, so that the electromagnetic wave interacts with the electron beam to amplify the signal. The metal wire is called a helix, which is the carrier of high-frequency energy and electron beam energy exchange and high-frequency energy transmission. The ...
