Description

Technical Field

[0001] The utility model relates to the technical field of beam welding machine tooling, in particular to an auxiliary fixing tooling for beam welding machines. Background Art

[0002] Electron beam welding (EBW) is a sophisticated welding device that utilizes a high-speed electron beam to bombard the workpiece, representing the highest level of welding performance. Vacuum EBW utilizes a directed, high-speed electron beam to impact the workpiece, converting kinetic energy into thermal energy, melting the workpiece and forming the weld. The electron beam's energy density reaches as high as 108 watts / cm², rapidly heating the weld metal to very high temperatures and capable of melting any refractory metal or alloy. It requires no filler material and is typically performed in a vacuum, resulting in clean, smooth welds free of oxidation defects.

[0003] Regarding the existing related technologies, the inventors believe that the following defects often exist: when the beam welding machine welds the workpiece, the shape of the workpiece may be square or round, and the current fixed tooling may only be able to clamp square workpieces when fixing the workpiece. When welding a round workpiece, the fixed tooling needs to be replaced to adapt to the round shape, and it cannot adapt to the fixing of square and round workpieces.

[0004] To this end, we propose an auxiliary fixing tool for beam welding machine welding. Utility Model Content

At the same time, under the threaded transmission action of the bidirectional screw rod 210 and the transmission bar 2 28, the two transmission bars 28 drive the clamping bars 2 29 to move toward the middle at the same time, clamping the workpiece between the two clamping bars 29.
