Abstract

The invention discloses an automobile door closure corner edge covering mechanism. The automobile door closure corner edge covering mechanism is characterized in that a lower step face is arranged at one end of a base, and lug shaft supporting blocks are arranged on the two sides of the lower step face respectively; an air cylinder base of an air cylinder is hinged to the lug shaft supporting blocks through pin shafts and can swing around the lug shaft supporting blocks to provide drive force; a pressing cutter is fixedly installed on the front end face of a pressing cutter installing block through a bolt, and the tail of the pressing cutter installing block is hinged to the end of a piston rod of the air cylinder through a pin shaft; the work face of the pressing cutter is provided with a profile matched with the workpiece corner closing digital analogy; and parallel four-bar mechanisms are symmetrically arranged on the two sides of the base and composed of two pairs of parallel connecting rods, the pressing cutter installing block and the base, the bottom ends of the connecting rods are hinged to the sides of the base, and the upper ends of the connecting rods are hinged to the sides of the pressing cutter installing blocks. The pressing cutter is driven through pushing of the air cylinder to carry out the edge covering action. The automobile door closure corner edge covering mechanism is stable in edge covering effect and good in forming performance.

Description

technical field [0001] The invention relates to an automobile corner hemming mechanism, in particular to an automobile door cover corner hemming mechanism applied in the hemming process of an automobile body-in-white. Background technique [0002] With the rapid development of the automobile industry and the frequent replacement of models, automobile manufacturers are in urgent need of highly flexible and high-tempo production lines. Robot hemming technology has the characteristics of high flexibility and small working area, and is widely used in the field of automobile door cover assembly. However, at the corners of the convex edge and the door corners, because the robot hemming is a local deformation, the hemming effect is not stable and it is extremely difficult to control. It will destroy the corner ridgeline and produce defects such as sharp points, waves, and warping deformation. Therefore, in the robot hemming process, the corners of the door cover are usually in the...
