The invention relates to a multi-
station welding fixture with external power supply used in the gas shielded weld, the
laser weld, and the vacuum election beam
welding. Without extra electromechanical
control system, the invention adopts common
welding revolving table as power supply and is not provided with
momentum and
control system, so the invention utilizes the revolving table
momentum to drive a plurality of components to spin and transform work stations, and realizes automatic multi-work-
station welding process. The design of the stopping step and the locking
handle realizes the transform between the work
station transformation and the component spin and matched revolving table, which can satisfy the welding requirements of gyrating
welding joint at any angle form 0 to 90 degrees. The invention has the advantages that: when welding, in particular to precision welding such as the
laser welding and the election beam welding, the standby time due to
assembly is decreased, and work efficiency is improved.
