Title:
SEAM WELD LINE AUTOMATIC COPYING DEVICE
Document Type and Number:
Japanese Patent JP3434122
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To eliminate a high cost copying jig required for seam welding and complicated program, etc., for a robot to support a work.
SOLUTION: An XY table 50 as a support means of a fuel tank 2, which allows movement in arbitrary horizontal direction and restricts movement in horizontal turning direction, and a copying control shaft 84 having a spindle in the direction orthogonal to the moving allowable direction of XY table 50 are stacked up/down. Either one of the XY table 50 or copying control shaft 84 is supported with the tip of a robot arm 82, on the other, a special jig 6 to support the fuel tank 2 having a part to be seam welded is mounted. A forming direction of the weld line in fuel tank 2 is changed/controlled by rotation of the copying control shaft 84. Control of the copying control shaft 84 is executed based on the output of a range sensor 98 to detect the interval between a template 92 mounted to the special jig 6 and a reference member 96.
