Anti-sputtering device for electron beam welding

Abstract

The invention relates to the field of electron beam welding, in particular to an electron beam welding anti-sputtering device. An electron beam welding anti-sputtering device comprises an anti-sputtering baffle, an expansion piece, a supporting table, a clutch hub, a sun gear and a combination part. The sun gear is a sun gear of a planetary gear mechanism, a joint surface of a clutch hub and a joint surface of the sun gear form a joint part, and the sun gear forms a welding part of electron beam EB work welding, and is formed into a circular ring shape surrounding a rotating shaft X at a predetermined interval when viewed from the direction of the rotating shaft X. The anti-splashing device solves the problems that splashing generated during welding cannot be completely prevented, deviation is still generated during welding of a clutch hub and a sun gear, and meanwhile splashing still exists.

Description

technical field [0001] The invention relates to the field of electron beam welding, in particular to an anti-sputtering device for electron beam welding. Background technique [0002] In the prior art, the electron beam is controlled by the magnetic field to move rapidly in different positions, rapidly impact the workpiece, form a molten pool, and realize the welding of the connection between the two workpieces. The magnetic field or workpiece magnetic field interference will cause trajectory deflection and affect the welding effect. Therefore, in the process of electron beam welding, vacuum conditions must be adopted. Therefore, manual participation cannot be allowed during the time when the workpiece is placed and waiting for processing and before the processing is completed; [0003] Vacuum electron beam welding uses fast moving electrons and uses kinetic energy to impact the workpiece to generate thermal energy to form a molten pool to complete the welding principle.

Problems solved by technology

[0005] The existing invention prevents the deformation of the workpiece when it is displaced to the electron beam torch by abutting the abutting part against the slope of the boss part and the connecting part, and thereby prevents the spattering problem during welding. However, due to the abutment The joints of the parts facing the clutch hub and sun gear of different sizes need to be replaced with suitable abutment parts, and the abutment parts cannot completely offset all the stress generated during the displacement process because they are against the slope of the workpiece connection;

[0006] Due to the rigid structure of the abutment parts and the inability to move laterally, there is still a distance from the welding part, which cannot completely prevent the spatter generated during welding, resulting in the deviation of the clutch hub and the sun gear during welding. sputtering problem;

[0007] Therefore, the existing technology / design is flawed;
