Abstract

The application discloses a vacuum welding device and its installation and use method. There are side wall adjustment columns on the left and right sides of the bottom base of the vacuum welding device. There is a top pressure plate above the base, and the top pressure plate and the bottom base are connected and fixed by the first fixing piece; the upper part of the side wall adjustment column is located in front of the upper part of the longitudinal part of the U-shaped structure of the main body, and the upper part of the side wall adjustment column has front and rear respectively. The adjustment screw in the direction; the bottom base outside the side wall adjustment column is connected with a magnetic shield adjustment screw; it ensures that the vacuum sealing of multiple key parts of the main body is completed at the same time, and avoids uncontrollable shape and position tolerances caused by multiple processes; applicable The assembly is welded in a high-temperature vacuum environment to ensure the shape and position tolerances of its key positions, and to ensure that the path of cesium atoms is smooth and does not deviate; the main body can be welded once and can be used for a long time, and the yield of cavity components can be improved.

Description

technical field [0001] The present application relates to the technical field of main body welding and manufacturing, and relates to a vacuum welding device and an installation and use method. Background technique [0002] At present, the main body is a key component of cesium clock physics. How to assemble and weld the various structures of the main body is a key issue in its application process. For this reason, a vacuum welding device is needed so that the main body can be smoothly placed in a high-temperature vacuum environment. The assembly is welded down to ensure the shape and position tolerances of its key positions, thereby ensuring that the path of the cesium atoms is smooth and does not deviate. The Chinese utility model patent document whose notification number is CN204248234U discloses a welding device for cesium release agent for electric vacuum, including a material tube box, a material tube feeding device, two casing boxes, two sets of casing feeding devices,...
