BOTTOM PART OF CAR BODY WELDING DEVICE IN CAR WELDING LINE

摘要

The present invention is an apparatus for welding the lower panel in the main buck jig process of the assembly line of the automobile to apply a multi-joint 6-axis robot to extend the welding range and shorten the cycle time by the effect and attach to the jig The jig was simplified by eliminating the pile gun, and the continuous welding operation of the tip of the car, and the automatic tip dressing device can be installed when the wear on the car body welding line to maximize the line operating time The structures (1) and (1 ') are installed on the left and right sides of the vehicle (C) mounted on the welding line of the vehicle, and the upper joint 6-axis robot (2) (2') for welding the upper panel of the vehicle (C). ) In the welding line of a vehicle equipped with), the articulated six-axis robot (4) (4 ') is installed at the bottom of the main buck without attaching a dummy gun to the main buck jig (3) for fixing the side panel. A part who can weld up to a part Underbody welding device in the car welding line.
