Abstract

The invention provides an assembly process of a magnetron anode assembly. The process comprises the following steps of S1, loading an anode plate into an anode cylinder to form an anode cylinder assembly; S2, arranging a grading ring on the anode cylinder assembly; S3, assembling the A side of a magnetic pole by utilizing an A side die; S4, assembling an antenna by using a first positioning die and a second positioning die; S5, welding; S6, disassembling the die; S7, removing a central pin, and correcting the antenna; S8, adjusting the frequency, and installing the K side of the magnetic pole,wherein the anode cylinder assembly comprises an anode cylinder, an anode plate and the center pin. According to the present invention, the anode plate is tightly pressed on the inner circumferentialsurface of the anode cylinder by adopting the center pin, so that the anode plate and the anode cylinder are ensured not to generate relative displacement in the anode assembly assembling process, the assembling precision is ensured, and the antenna groove is ensured to be formed in the middle position of an antenna hole in the magnetic pole A side through the arrangement of a magnetic pole A side positioning die; by arranging the antenna positioning die, the position precision of the antenna is ensured; and by adopting the production process formed by the die, the assembly precision of the magnetron anode assembly is ensured, and the product percent of pass is improved.

Description

technical field [0001] The invention relates to the field of magnetrons for generating microwave equipment, in particular to an assembly process of magnetron anode components. Background technique [0002] A magnetron is an electric vacuum device used to generate microwave energy. It is essentially a diode placed in a constant magnetic field. Under the control of a constant magnetic field and a constant electric field perpendicular to each other, the electrons in the tube interact with the high-frequency electromagnetic field. , Convert the energy obtained from a constant electric field into microwave energy, so as to achieve the purpose of generating microwave energy. The magnetron is characterized by high power, high efficiency, low operating voltage, small size, light weight, and low cost. [0003] More specifically, the magnetron device has a spiral cathode, a cylindrical anode body arranged with the cathode as a central axis, and radially arranged in the inner space of ...
