Description

Technical Field

[0001] The utility model relates to the technical field of vacuum electron beam welding, and more specifically, it relates to a vacuum electron beam welding machine. Background Art

[0002] An electron beam welding machine is a relatively precise welding device that uses the principle of bombarding a workpiece with a high-speed electron beam current for welding processing, and basically represents the highest performance welding level. In vacuum electron beam welding, during the welding process, a directed high-speed electron beam current impacts the workpiece, converting kinetic energy into heat energy to melt the workpiece and form a weld seam.

[0003] Currently, the Chinese patent with the application number CN202320233113.0 discloses a vacuum electron beam welding machine that is convenient for loading and unloading. It includes a beam welding machine body and a platform. A welding chamber is fixedly installed on the platform, the beam welding machine body is arranged above the welding chamber, a welding chamber door is movably installed on the side wall of the welding chamber, a first electric telescopic rod is fixedly installed on the platform, and the telescopic end of the first electric telescopic rod is fixedly connected to the welding chamber door. An installation rod is fixedly installed on the inner wall of the welding chamber door, and one end of the installation rod is rotatably installed with a welding table through a connecting shaft. By the contraction of the telescopic end of the first electric telescopic rod, the welding chamber door can be driven to open while pulling the welding table out of the welding chamber. By the extension of the first electric telescopic rod, the welding chamber door can be closed while pushing the welding table into the welding chamber, thus facilitating the placement and taking of workpieces to be welded. However, usually only one group of workpieces can be welded at a time. After the welding of the workpieces in the welding chamber is completed, the workpieces are taken out, and then the welding of the next group of workpieces is carried out. It is inconvenient to quickly switch multiple groups of weldments, making the welding process too cumbersome and complex. Summary of the Utility Model

[0006] A vacuum electron beam welding machine includes a beam welding machine body and a workbench. It is characterized in that it further includes a welding chamber and a movable door. The welding chamber is fixed on the workbench, the beam welding machine body is placed on the top of the welding chamber, the movable door is hinged to the welding chamber. A rotating mechanism is provided on the workbench. The rotating mechanism includes a welding table, a rotating disk, a rotating shaft, a first motor, a second motor, and a gear. The first motor is fixed in an installation groove, the bottom of the rotating disk is fixedly connected to the output end of the first motor, a receiving groove is opened on the top of the rotating disk, the welding table is placed on the rotating disk, and the output end of the second motor passes through the welding table and extends into the receiving groove. The gear is placed in the receiving groove and sleeved on the output end of the second motor. A number of teeth meshing with the gear are provided in the receiving groove.

[0007] Further, it is arranged that the moving mechanism includes two slide rails, two sliders and a cylinder. The two slide rails are fixedly arranged in parallel in the welding chamber.
