AI Technical Summary

Technical Problem

The sealing structure of existing local vacuum welding devices is prone to suction and detachment during vacuum welding, as well as circumferential movement or radial rolling caused by uneven friction, resulting in the inability to maintain a stable vacuum level.

Method used

It adopts an inverted trapezoidal structure that combines an insert ring with an assembly ring groove, combined with a filling ring cavity and an anti-slip structure. It uses high-temperature resistant elastic materials and is equipped with an active cooling circulation system to form a wedge-shaped anti-detachment and redundant sealing barrier, ensuring the stability of the sealing structure.

Benefits of technology

It effectively reduces the probability of the sealing structure detaching and shifting during vacuum welding, ensuring the stability of the vacuum level and the welding quality, and improving welding efficiency and reliability.

Abstract

本发明提供一种局部真空激光焊接装置,属于真空激光焊接设备设计领域,焊接装置包括真空罩以及密封结构,真空罩具有与待焊工件相对设置的罩孔,罩孔的外周罩体朝向待焊工件一侧的端面上形成有环绕罩孔设置的组装环槽,密封结构包括弹性密封环件,弹性密封环件包括处于其远离待焊工件的一侧的嵌装环,嵌装环过盈嵌装于组装环槽内,组装环槽的横截面为上大下小的倒梯形,嵌装环与组装环槽形状适配。本发明有效降低在焊接过程中内外压差作用下弹性密封环件与真空罩发生脱离的概率,同时还能够有效降低焊接过程中弹性密封环件与待焊工件之间的摩擦力不均导致周向窜动或者径向翻滚的发生概率,确保焊接过程中真空度稳定维持。
