[0019] The utility model provides Figure 1-5The illustrated electron beam welding butt fastening tool comprises a long filament 1 disposed within a tube 2. Both ends of the long filament 1 extend beyond the tube 2 and are provided with a second end cap 3 and a first end cap 4, respectively. The second end cap 3 and the first end cap 4 are respectively clamped onto the ends of the tube 2. One surface of the first end cap 4 is provided with a fastening nut 7 for fastening the first end cap 4. The second end cap 3 includes a disk 31, the center of which is provided with a threaded sleeve 32. One end of the long filament 1 passes through the first end cap 4 and is threadedly connected to the threaded sleeve 32.

[0020] One end of the filament 1 is screwed into the threaded sleeve 32 so that one side of the disc 31 is in close contact with one end of the tube blank 2, and the other end is fastened to the end of the tube blank 2 by the fastening nut 7. After fastening, the end is prevented from being offset during electron beam welding.

[0021] like Figure 1 As shown, the size of the inner wall of the end piece 4 is adapted to the cross-sectional size of the tube blank 2, and the outer wall of the end piece 4 is provided with a heat dissipation hole 5, which is communicated with the inner cavity of the tube blank 2;

[0022] By providing the heat dissipation holes 5 , the heat generated by the end during electron beam welding can be discharged in time, thereby preventing the tube blank 2 from being deformed due to high temperature.

[0023] like Figure 1 and Figure 4 As shown, a through hole 6 is opened at the center of the end 1 4 , and the size of the through hole 6 is smaller than the size of the fastening nut 7 .

[0024] like Figure 2 and Figure 3 As shown, the long screw rod 1 includes a plurality of screw rods 11, and adjacent ends of the plurality of screw rods 11 are provided with plug-in components, and two adjacent screw rods 11 are connected by the plug-in components, and the plug-in components include two plug rods 8 and a socket 9 adapted to the plug rods 8, and the plug rods 8 and the socket 9 are respectively provided at adjacent ends of two adjacent screw rods 11;

[0025] By inserting the insert rod 8 into the insert hole 1 9 , the screw rod 11 can be spliced ​​into the long screw rod 1 , and then corresponding adjustments can be made when facing tube blanks 2 of different lengths.

It is only necessary to insert the plug rod 8 of one screw rod 11 into the socket 9 of the other screw rod 11 to splice it into the long screw rod 1. At this time, the plug rod 8 inserted into the socket 9 will have a certain friction to prevent the two screw rods 11 from separating. According to the length of the tube blank 2, the corresponding screw rod 11 can be added. Then, the concave surface of the end head 4 is clamped at the other end of the tube blank 2. After clamping, one end of the long screw rod 1 is extended into the tube through the through hole 6 of the end head 4.
