Description

Technical Field

[0001] The utility model relates to the technical field of vacuum electron beam welding, in particular to vacuum electron beam welding equipment for composite plate blanks. Background Art

[0002] Electron beam welding is a welding process that uses an electron beam as a heat source. When the cathode in the electron beam generator is heated to a certain temperature, electrons escape. The electrons are accelerated in a high-voltage electric field and focused by an electromagnetic lens to form an electron beam with extremely high energy density. When the electron beam bombards the welding surface, most of the kinetic energy of the electrons is converted into heat energy, causing the metal at the joint of the weld to melt. When the weldment moves, a continuous weld is formed at the joint of the weldment.

[0003] For example, CN220073541U2 discloses a vacuum electron beam welding device for composite plate blanks. A water pump is set up to drive the coolant in the cooling pipe to flow. When the coolant in the cooling pipe flows, it takes away the heat on the placement plate. The coolant moves to the heat dissipation pipe to exchange heat with the water in the water tank to achieve rapid heat dissipation. The hand wheel can drive the interference screw to pressurize the plate to prevent the two plates from shaking. The ball bearing can change the sliding connection between the sleeve and the support rod into a rolling connection, making the movement of the two smoother. The screw rod is connected to the box body through the bearing, making the rotation of the screw rod smoother. By disassembling the cooling pipe and the heat dissipation pipe, and then removing the fastening bolts, the placement table can be removed and replaced with a placement table of other sizes.

[0004] However, when the welding equipment is performing welding work, since only one group of welding blanks can be placed on the placement plate at a time, frequent loading, unloading, vacuuming and welding are required during mass production, which leads to low welding efficiency. In addition, when placing the blank in the placement groove, the two ends of the blank need to contact the inner wall of the placement groove so that the contact screw can accurately push the blank to move. If the shape or size of the blank does not match the placement groove, the weld seam of the blank side pushed by a single screw is prone to tilt or offset, thereby affecting the blank processing effect.
