Problems solved by technology
[0003] At present, common sealing devices have temporary sealing structures or valves. After welding and sealing, vacuum damage is often caused, and the high vacuum state after sealing cannot be guaranteed, and the reliability is poor; or the sealing can only be carried out in a full vacuum environment. If the vacuum degree of the vacuum chamber is not high, it cannot meet the requirements for use

Embodiment Construction
[0019] The following structural drawings and working principle will further describe the present invention:
[0020] like figure 1 The shown tooling for vacuum welding and sealing in an atmospheric environment includes a target vacuum container outer shell 1 and a target vacuum container inner shell 6, the target vacuum container outer shell 1 is provided with a plugging hole, and the target vacuum container outer shell 1 is provided with a plugging hole. There is a guide sleeve box 2, a through hole is arranged inside the guide sleeve box 2, and a blocking punch 3 is arranged in the through hole, and the through hole plays a guiding role for the blocking punch 3, and the bottom of the blocking punch 3 is blocked. A positioning hole is provided, and a welding plugging head 5 is movably installed in the positioning hole. The positioning hole plays a positioning and guiding role for the welding plugging head 5, and the welding plugging head 5 matches the plugging hole of the tar...

The invention belongs to the technical field of vacuum plugging devices, in particular to a tool for vacuum welding and plugging in an atmospheric environment. The tool comprises a vacuum container outer shell and a target vacuum container inner shell; a plugging hole is formed in the vacuum container outer shell; a guide sleeve box is arranged at the plugging hole of the vacuum container outer shell; a through hole is formed in the guide sleeve box; a plugging punching rod is arranged in the through hole; a positioning hole is formed in the bottom of the plugging punching rod; a welding and plugging plug is arranged in the positioning hole; the welding and plugging plug is matched with the plugging hole of the vacuum container outer shell; a vacuumizing port is formed in one side of the guide sleeve box; the vacuumizing port communicates with a through hole in the guide sleeve box; and the vacuumizing port is connected with a vacuum pump. Welding and plugging are performed on the premise of not damaging a high vacuum state; the requirement on a full-vacuum high-vacuum environment is omitted; a method is reliable; the tool is simple and convenient to use; and the requirement on high-vacuum degree after plugging can be effectively guaranteed.
Description
technical field [0001] The invention belongs to the technical field of vacuum sealing devices, and in particular relates to a tool for vacuum welding and sealing in an atmospheric environment and a method for using the same. Background technique [0002] A certain type of high vacuum container, the structure is a double-layered lining structure, which are the outer shell of the target vacuum container and the inner shell of the target vacuum container. The outer shell of the target vacuum container is used to withstand internal pressure and external pressure, and the inner shell of the target vacuum container is used to withstand The medium is corroded, the two require precise fit, and the fit rate requires 100%. During the nesting process of the inner and outer shells, the gas remaining on the bonding surface must be discharged through a plugging hole at the bottom of the outer shell, and then the depth of the bonding surface is evacuated to an absolute pressure below 10Pa ...
