Hemming working method and working apparatus
A moving die is held by a robot and made to approach a vehicle, and a positioning pin is inserted into a positioning hole of the vehicle. The moving die is brought into a floating state of being displaceable relative to the vehicle by reducing a force of the robot for maintaining an attitude thereof. In a state of holding the moving die by the robot, a surface of the moving die is brought into contact with the vehicle by an adsorbing mechanism including an adsorbing portion of an elastic member provided to the moving die. The moving die and the robot are cut to be separated.
1. A hemming working apparatus having a hemming roller for carrying out hemming working for a flange of a work, the hemming working apparatus comprising:
a rotating shaft that rotatably supports the hemming roller so as to define a hemming roller rotation axis;
a moving mechanism that supports the hemming roller through the rotating shaft and moves the hemming roller to a predetermined position; and
a guide member that guides the hemming roller along the flange while restricting a displacement of the hemming roller relative to the flange along the hemming roller rotation axis;
wherein the hemming roller is displaceable along the hemming roller rotation axis relative to the moving mechanism while the hemming working apparatus is hemming the flange.
