Detailed description of the invention
Below with reference to drawings and Examples, the utility model is further described:
nullSee shown in accompanying drawing 3，This kind of Superconducting Niobium Cavity threeway beam tube electron beam Clamp for welding，It is characterized in that: this fixture includes a chuck rotating shaft 1，The sill 2 of one strip is set at chuck rotating shaft 1 top，It is connected with by centre bore between chuck rotating shaft 1 and sill 2，Left socle 3 and the right support 10 of strip are installed by bolt respectively in the both sides of sill 2，The entablature 4 of strip is connected between the top of left socle 3 and right support 10，The left end of entablature 4 is bolted on the right flank of left socle 3，The right side of entablature 4 is processed into cylinder and is connected with the installing hole on right support 10，It is provided with a left side between installing hole on this cylinder and right support 10、The rotation nut 9 that dextrorotation is entered，On entablature 4, plug-in mounting fixes a threeway beam tube pull bar 7，The cover plate 8 being provided above plate-like on threeway beam tube of threeway beam tube pull bar 7，Entablature 4 is set with threeway beam tube left cover 5 and the threeway beam tube right cover plate 6 of plate-like，Wherein，The left surface of threeway beam tube left cover 5 is close on the right flank of left socle 3，Threeway beam tube right cover plate 6 press-fits by rotating nut 9 and is fixed on the step surface of entablature 4，This step surface is the list structure interface with cylindrical-shaped structure of entablature 4 right part，The axis of threeway beam tube pull bar 7 is coaxial with the center line of the centre bore of chuck rotating shaft 1.
