Abstract

The invention discloses a centering and positioning fixture for automobile assembly, which comprises a positioning support provided with a workpiece positioning pin. A Z-directional support block is arranged at the bottom end of the positioning support; X-directional positioning pins are arranged on two sides of the positioning support positioned in the X direction of an automobile respectively; centering and positioning mechanisms are arranged on two sides of the positioning support positioned in the Y direction of the automobile respectively; and central lines of the centering and positioning mechanisms are overlapped. The centering and positioning fixture is used for centering and positioning workpieces when the workpieces are assembled, assembly adjusting time is shortened, assembly adjusting operation is decreased, the labor intensity of staff is reduced, errors of workpiece assembly are decreased, and production assembly efficiency, product quality and production efficiency are simultaneously improved.

Description

technical field [0001] The invention relates to the technical field of automobile assembly, in particular to a centering and positioning tool for automobile assembly. Background technique [0002] At present, in the process of automobile assembly, the matching between parts is difficult and indispensable during the assembly of automobile parts; In addition to positioning in the X and Z directions, it is also necessary to meet the clearance requirements in the Y direction. It is necessary to ensure that when the workpieces such as the engine hatch, luggage compartment cover, front and rear headlights are positioned in the Y direction, the gap between the two sides of the workpiece and the edge is equal before the assembly can be completed. Wherein, the X direction of the car is the direction from the front of the car to the rear of the car, the Z direction of the car is the direction from the chassis to the roof of the car, and the Y direction of the car is the direction from...
