Abstract

The invention discloses an intelligent positioning and welding system for an automobile CD column body part and a working method of the intelligent positioning and welding system, and particularly relates to the technical field of automobile part welding. After the automobile C column body part and the automobile D column body part on the two sides of a welding box move towards an overturning assembly to get close and enter opposite grooves, the end faces of the automobile C column body part and the automobile D column body part are kept to be corrected and attached; a second clamp unit and a third clamp unit conduct self-adaptive positioning according to the thickness, a bracket rotates twice, firstly, the bracket rotates by 90 degrees clockwise to drive the automobile C-column automobile body part and the automobile D-column automobile body part which are clamped together to be in the horizontal state from the vertical state, then an overturning assembly moves along with a circulating frame, and the overturning assembly is driven to rotate by 90 degrees clockwise to drive the automobile C-column automobile body part and the automobile D-column automobile body part to be in the horizontal state from the vertical state to the horizontal state. The automobile CD column automobile body parts enter different welding sealing bins, and the front faces of the joints of the automobile CD column automobile body parts are welded through an upper welding unit; and the bracket rotates to the lower position along with the circulating frame, the bracket rotates by 180 degrees anticlockwise, and the welding unit below performs reverse side welding and double side welding on the connecting position of the CD column and the automobile body part of the automobile.
