This utility model discloses an eccentric adjustment device for the cathode end cap and anode cylinder of a magnetron, including an indexing turntable assembly and a carrier cylinder. The indexing turntable assembly has a turntable, and the carrier cylinder is rotatably mounted on the turntable. It also includes a vision system, comprising a camera for upward imaging of the output end cap and the connecting ring; a carrier cylinder rotation drive mechanism for driving the magnetron assembly to rotate, including a carrier cylinder servo motor that drives the carrier cylinder to rotate; a pressing assembly, including a pressing block servo motor and a pressing block for pressing down the top outer periphery of the ceramic shaft, the pressing block servo motor driving the pressing block to move up and down; and a control system, which is signal-connected to the vision system and controls the indexing turntable assembly, the carrier cylinder rotation drive mechanism, and the pressing assembly. This eccentric adjustment device for the magnetron cathode end cap and anode cylinder improves the effectiveness of eccentric adjustment and increases work efficiency.

Vacuum electronic devices (VEDs) having multiple two-dimensional layers of various materials are bonded together to simultaneously form one or more VEDs. The two-dimensional material layers are machined to include features required for device operation, such that when assembled and bonded into a three-dimensional structure, three-dimensional features are formed. The two-dimensional layers are bonded together into a sandwich-like structure. The manufacturing method is capable of incorporating metal materials, magnetic materials, ceramic materials, and other materials as required for VED fabrication, while maintaining the required positional accuracy and ability to produce multiple devices per batch.

The application provides an automatic correction tool for a magnetron anode antenna, which is used for correcting an antenna of an anode assembly of a magnetron and comprises a workbench and a track horizontally arranged on the workbench, wherein a sliding die holder is arranged on the track and can slide along the track, and the anode assembly is arranged on the sliding die holder. The automatic correction tool for the magnetron anode antenna can automatically correct the assembled anode assembly in a pipeline mode without any difference. Before correction, whether the anode assembly is qualified or not and whether the antenna is inclined or not, after correction, the anode assembly is definitely qualified and the antenna is definitely vertical and perpendicular to the upper end surface of the anode shell. Compared with traditional manual quality inspection and correction, the automatic correction tool has the advantages of greatly improved correction speed and efficiency, no missed inspection, good correction quality, effectively improved production efficiency and yield of the anode, and further improved production efficiency and yield of the subsequent tube core and magnetron.

This invention discloses an assembly method and assembly fixing structure for an electron gun, belonging to the field of electron gun manufacturing. It includes a base, with a pedestal integrally formed at the center of the upper surface of the base. A turntable is rotatably connected to the outer surface of the pedestal. A slide is symmetrically fixed to the upper surface of the turntable. A cover plate is provided above the pedestal, and a sliding shaft is symmetrically fixed to the outer surface of the cover plate. A rotating sleeve is fitted around the sliding shaft. This invention drives the control grid to rotate 360 ​​degrees horizontally by rotating the turntable. Through gear meshing and threaded lifting, the lifting frame one slides to achieve left and right flipping of the control grid with the right-side rotating shaft as the fulcrum. An operating screw drives the lifting frame two and the movable rod to raise and lower, completing the forward and backward pitch of the control grid with the two sliding shafts as the fulcrums. These three adjustment dimensions are independent and can be linked, enabling precise alignment of the control grid and the shadow grid in all directions without blind spots, meeting the angle matching requirements of high-precision assembly.
