Document Type and Number:
Japanese Patent JP3860365
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To execute the joining by a laser beam spot welding with which a break due to a plastic deformation hardly occurs even when frequent and extreme bending is applied to a part near welded and joined parts of a flexible pipe.
SOLUTION: Chucks 4a, 4b, and 5 which clamp a flexible pipe and a metallic part 2 are all arranged on an axis and freely and rotatably supported. Each of chucks 4a, 4b and 5 has a chuck pulley 17, 18a, and 18b, respectively. Each of the chuck pulleys 17, 18a, and 18b is connected with pulleys 13, 14a, and 14b, respectively, each of which is engaged in a splined shaft 12 via timing belts 15, 16a, and 16b, respectively. The splined shaft 12 is connected with an electric motor 10 and the electric motor 10 is connected with a motor driving controller 11. A laser beam emission head 6 is freely and movably supported on a head slider 8 via a head mounting part 7, on the axis line of the chucks 4a, 4b, and 5.
