Abstract

The invention discloses a vacuum laser welding system for a grillwork and belongs to the technical field of laser welding. The vacuum laser welding system meets the requirements for the welding environment of the zirconium alloy grillwork and high precision. A laser welding head of the vacuum laser welding system is fixed to a three-dimensional movement mechanism. The three-dimensional movement mechanism drives the laser welding head to move. A laser signal input port of the laser welding head is connected with a laser signal output port of a laser device through an optical cable. A vacuum room is arranged under the laser welding head. The vacuum room is an airtight rectangular box body. Light-transmittance glass is arranged on the upper side wall of the box body. A worktable is arranged under the light-transmittance glass. The worktable is arranged on the bottom face of the vacuum room. A servo system drives the worktable to rotate and overturn through a workpiece position-changing mechanism. An argon charging opening and an exhaust opening are formed in the left side wall of the vacuum room. The vacuum laser welding system is suitable for welding the grillwork.

Description

technical field [0001] The invention belongs to the technical field of laser welding. Background technique [0002] At present, the welding equipment for the grid structure cannot meet the requirements of the water and oxygen content of zirconium alloy welding for the atmosphere before welding, and the movement accuracy of the equipment cannot meet the welding requirements of various welds of the grid. The optical path transmits the laser light in the way of lens refraction and reflection, and the beam transmission path will be changed due to factors such as mechanical movement and environmental temperature and humidity. Long vacuuming time and long waiting time for workpiece welding cannot meet the needs of high-efficiency production. Contents of the invention [0003] The present invention proposes a grid vacuum laser welding system in order to adapt to the environment and high-precision requirements of zirconium alloy grid welding. [0004] The grid vacuum laser weldi...
