A kind of plane window as above and a bracer assembly-welding device, wherein, two, left and right gripper shoe in described three gripper shoes is arranged symmetrically with, close end in two gripper shoes in left and right arranges locating piece, and the phase backside in two gripper shoes in left and right arranges the fastening assembly being made up of bolt and regulation fastening block.
A kind of plane window as above and a bracer assembly-welding device, wherein, described channel-section steel is offered the screwed hole of 14 M20, is used for penetrating depression bar and compresses it.
A kind of plane window and a bracer assembly welding method, comprise the steps:
Step one: workpiece is placed
Soldered midplane window is placed on special plane window with supporting block assembly and props up on bracer assembly-welding device so that midplane window is placed in two, the left and right gripper shoe of plane window and a bracer assembly-welding device, and a bracer is placed on intermediate support plate；
Step 2: fixing
By soldered midplane window and the tight locating piece of medial roof supporting block assembly, midplane window inside contraction distortion during to prevent from welding, with bolt and regulation fastening block, soldered midplane window is fixed with supporting block assembly,
The screwed hole of 14 M20 on channel-section steel penetrates depression bar；
Step 3: welding
Centering plane window welds with supporting block assembly.
This is the most novel have the advantage that in a vacuum chamber plane window and bracer assembly welding time, ensure that its relative size controls welding deformation while requiring by this device and welding method thereof, the concordance simultaneously ensureing 5 midplane windows and support block assembly size, improves welding efficiency.
