AI Technical Summary
Technical Problem
Existing welding fixtures cannot accommodate the uneven warping of the inner cylinder caused by flatness errors and thermal expansion deformation, resulting in increased clamping force or ineffective clamping in local warped areas, affecting welding quality and sealing performance.
Method used
Pneumatic clamps are used to achieve dynamic air pressure balance through multiple displaceable pressing components and gas linkage components, and adaptively adjust the clamping force to compensate for workpiece deformation and ensure uniform welding gap.
Benefits of technology
It achieves dynamic and balanced clamping force during the welding process, avoids workpiece damage, improves welding strength and sealing performance, and ensures welding quality.

Abstract
本发明公开了一种空气弹簧盖板焊接用气动夹具，其中盖板与构成空气弹簧的内筒进行焊接，气动夹具包括多个搭接于内筒顶端并可位移的压合组件，以及用于驱动每一压合组件位移的驱动组件。焊接作业时，外部气源通过所述气体联动组件向所有气动驱动件同步供给压力气体，各气动驱动件进而驱动对应的联动件，带动搭条向下直线运动，使其抵压于内筒的顶端，由于各气动驱动件通过气体联动组件相互连通，其内部气压处于动态平衡状态，当某一处内筒的顶端因焊接热影响出现翘边时，该处的搭条会被翘起的部位反向顶升。
