Intelligent rolled edge pressing system for robot and process method

Abstract

The invention discloses an intelligent rolled edge pressing system for a robot and a process method. The intelligent rolled edge pressing system for the robot comprises a six-degree-of-freedom parallel robot, a rolling mechanism, a rotary workbench, a pressing bottom die, automatic-control equipment and safe equipment, wherein the rolling mechanism consists of a flange plate, a connecting rod, a rolling head mounting block, a flat idler wheel, a straight idler wheel and a step wheel, and the flat idler wheel, the straight idler wheel and the step wheel are installed on the mounting block. The connection relationship of a main body is as follows: the six-degree-of-freedom parallel robot is connected by the flange plate and drives the rolling mechanism to enable a roller to move along the wrapping direction, a workpiece is arranged on the rotary workbench, and the other edge of the workpiece becomes an edge to be wrapped due to the rotation of the rotary workbench. The intelligent rolled edge pressing system for the robot, which is disclosed by the invention, has the advantage of high precision, and the wrapped edge forming quality is enabled to be good; a workbench has a bigger flexibility on workpieces of various shapes due to the controllability of the workbench; arrangement errors introduced in by multi-time clamping are avoided; and the processing time is shortened so as to improve the wrapping efficiency and the wrapping quality.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a robot intelligent hemming pressing system and a process method in the automobile manufacturing industry. Background technique [0002] At present, the connection of the inner and outer panels of the automobile body door cover usually uses the hemming process. When using traditional molds and presses for stamping and hemming, since the hemming contour of the outer panel changes according to the shape of the vehicle body, the angle of hemming along the entire contour is also different, and the area where the hemming transition is sharp and the hemming angle is too high In a large area, it will be very difficult to wrap the edge. At the same time, traditional stamping hemming molds occupy a large area, are costly, and have poor flexibility. In order to shorten the automobile development cycle and improve product competitiveness, new inner and outer panel connection technol...

Problems solved by technology

When using traditional molds and presses for stamping and hemming, since the hemming contour of the outer panel changes according to the shape of the vehicle body, the angle of hemming along the entire contour is also different, and the area where the hemming transition is sharp and the hemming angle is too high For large areas, hemming will be very difficult

At the same time, traditional stamping hemming molds occupy a lot of land, have high cost and poor flexibility. In order to shorten the automobile development cycle and improve product competitiveness, new inner and outer panel connection technology and robot hemming technology are gradually applied in body production
