Workpiece feeding rack limiting device for intelligent robot rolled hemming system

Abstract

The invention discloses a workpiece feeding rack limiting device for an intelligent robot rolled hemming system. The workpiece feeding rack limiting device comprises an X-direction limiting rack, wherein workpiece feeding table X-direction pressing blocks and workpiece feeding table X-direction side proximity switches are separately arranged at two ends of the X-direction limiting rack; an X-direction limiting air cylinder mounting plate is arranged in the middle of the X-direction limiting rack; a workpiece feeding table X-direction limiting air cylinder and a workpiece feeding table X-direction pressing head are arranged on the X-direction limiting air cylinder mounting plate; a workpiece feeding table X-direction middle guide frame is also arranged in the middle of the X-direction limiting rack; an X-direction guide groove and a workpiece feeding table X-direction middle proximity switch are formed in the upper surface of the workpiece feeding table X-direction middle guide frame; a workpiece feeding table muzzle brake is arranged at the tail end of the workpiece feeding table X-direction middle guide frame; the rack limiting device also comprises two Y-direction limiting racks; workpiece feeding table supporting frames are respectively arranged at the inner sides of the Y-direction limiting racks. According to the workpiece feeding rack limiting device disclosed by the invention, accurate positioning of the workpiece feeding rack of the intelligent robot rolling and hemming system is realized by accurate guiding in X, Y and Z directions; meanwhile, information about workpieces is acquired by sensing a signal of the workpiece feeding rack and is fed back to a master controller, and flexible production is realized.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing. The invention relates to an inner and outer panel hemming system in automobile manufacturing, in particular to a limit device for an upper part stand of a robot intelligent rolling hemming system. 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 impr...

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

[0003] In the robot intelligent rolling hemming system, the guidance and positioning accuracy of the workpiece directly affect the rolling quality of the workpiece, and even cause damage to the rolling equipment, resulting in huge economic benefits
