Abstract

The invention discloses a passive spring hemming assembly, which is in contact with the plate body to be hemmed of the automobile, and includes a bracket, the upper part of which is provided with a flange top cover connected with a mechanical arm, and the lower part is hinged with the bottom plate through a first hinge; a spring buffer , which is arranged between the flange top cover and the bottom plate; a cylinder, which is arranged between the spring buffer and the bottom plate, and the upper part of the cylinder is connected with the lower part of the spring buffer , the cylinder has an inner space for accommodating the guide rod, the upper end of the guide rod is in conflict with the spring buffer; the first rolling body is arranged on the lower part of the bottom plate, and the first rolling body includes multiple rollers of different shapes. The invention has the advantages of stable rolling force, simple debugging, low cost and the like.

Description

technical field [0001] The present invention relates to clamps for use in automobile manufacturing, and more particularly, the present invention relates to a passive spring hemming assembly. Background technique [0002] Car door cover hemming technology has now become an important process in the automobile manufacturing process. The application of hemming technology in the car body mainly includes car doors, machine covers, fenders and sunroof top covers, etc., and the hemming of door cover lines The methods mainly include press molding edging, desktop edging machine edging and robot rolling edging. Robot hemming technology is a new type of hemming technology, which has remarkable characteristics such as beautiful shape, easy realization of flexible production, low investment and maintenance costs, small working area, stable hemming quality and relatively short commissioning cycle. [0003] At present, the rollers in the robot hemming equipment are directly in contact with...
