VACUUM POST FOR THE MANUFACTURE OF AN ELECTROVACUUM DEVICE Russian patent published in 2022 - IPC H01J9/40 H01J9/385 

FIELD: vacuum technology.

SUBSTANCE: invention relates to vacuum technology and is intended for the manufacture and sealing of electrovacuum devices (EVD). The vacuum station for the manufacture of an electric vacuum device contains one evacuation vacuum system, a vacuum chamber with a heater and a device for fixing an electric vacuum device, a hydraulic mechanism for diffusion welding of a metal shaft. The hydraulic mechanism for diffusion welding is made in the form of a rigid self-centering frame with two hydraulic cylinders that transmit forces through sealed bellows units to pinch prisms located in the vacuum chamber, and the rods of the self-centering frame are located outside the vacuum chamber with the possibility of moving in longitudinal plain bearings, fixed relative to the vacuum chamber, chambers in a plane perpendicular to the longitudinal axis of the metal stem of the electrovacuum device.

EFFECT: increasing the reliability and quality of pumping, evacuation and diffusion welding of the EVD stem, reducing irreparable defects, simplifying the design of the post.
