Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a center-of-gravity adjustment mechanism of a workpiece transfer machine shared by multiple vehicle models, which is mainly suitable for improving stability and reducing maintenance costs. Background technique [0002] Among the existing automobile body-in-white welding fixtures, the solution for the transfer machine shared by multiple models is to use a clamping unit with multiple movable cylinders to achieve different widths and lengths. The bearing switches the overall center of gravity. The grabbing mechanism is connected to the lower part of the center of gravity adjustment mechanism composed of springs and ball linear bearings. When the grabbing mechanism grabs parts, due to the diversity of parts, the center of gravity is different, and the center of gravity will move forward, backward, left, and right. The offset mechanism of the center of the center of g...
