Automatic welding machine for clamping ring of piston rod of CDC shock absorber and control method

The invention discloses a CDC shock absorber piston rod clamping ring automatic welding machine and a control method, and relates to the technical field of automatic welding, the CDC shock absorber piston rod clamping ring automatic welding machine comprises a positioning tool, an auxiliary pressing mechanism, a symmetric synchronous welding mechanism and an automatic welding controller, the auxiliary pressing mechanism is used for positioning the to-be-welded clamping ring and the to-be-welded piston rod, provides rotating power during welding and is located on one side of the positioning tool. The positioning tool has the first effects that the to-be-welded clamping ring and the to-be-welded piston rod are positioned correspondingly, the auxiliary pressing mechanism presses the to-be-welded clamping ring and the to-be-welded piston rod correspondingly during welding, and the symmetrical synchronous welding mechanism is matched to achieve two-time welding and symmetrical surrounding type welding of four weld
