Clamping device for remote laser welding devices with stamps each being activated with a hydraulic fluid under pressure

摘要

On a clamping bed (10), plungers (26) extending telescopically, support the workpiece (14, 16). Bed and/or opposing support surface (12) include penetrations (32) for the laser welding beam (34). In novel design, the plungers are pressurized individually by hydraulic fluid. Bed and support have a mechanism for locking them together. The rods are biased toward retraction. They are arranged in groups, each individually pressurized. The bed includes a distribution block for the hydraulic fluid lines.
