This invention relates to a gear
welding device and method for a press, belonging to the field of press manufacturing. The technical solution is as follows: A gear
welding device for a press includes a work platform with a ground rail. A transfer trolley is movably mounted on the ground rail to carry the gear to be welded. Positioners are mounted on both sides of the ground rail, each equipped with a rotatable gripper. A gantry frame is also mounted on the work platform, spanning the ground rail. A
welding robot is movably mounted on the gantry frame, its movement direction being horizontal and perpendicular to the ground rail. The welding
robot is equipped with a
machine vision module. This solution, through the positioner
grippers, can precisely achieve 180° rotation of the gear, providing a stable posture adjustment basis for double-sided welding. The welding
robot, combined with the
machine vision module, enables automated and high-precision acquisition of weld information, providing data support for intelligent welding path planning.
