specific Embodiment approach
[0015] Referring to the accompanying drawings, the specific embodiments are as follows:
[0016] like figure 1 , 2 As shown, an electron gun protection device for a vacuum preheating electron beam welding device, the vacuum preheating electron beam welding device comprises a vacuum chamber 1, a moving platform 2 and a heating device 3 are arranged in the vacuum chamber 1, and the parts to be welded are placed On the mobile platform 2, the heating device 3 heats the workpiece to be welded by radiating heat radiation to realize pre-welding preheating of the workpiece to be welded. An electron gun 4 is installed on the side wall of the vacuum chamber 1, and one end of the electron gun 4 extends into the vacuum chamber 1. Internally, it is used for electron beam welding of parts to be welded.
[0017] like image 3 As shown, the electron gun protection device includes two sections of electrically controlled slide rails 5 that are arranged on the inner wall of the vacuum chamber...
