Title:
アーク溶接ロボットのトーチケーブル処理構造
Document Type and Number:
Japanese Patent JP4233503
Kind Code:
B2
Abstract:
A robot base (15) is installed on a ceiling (100), and a first wrist element (11) is attached to a front arm base (10) to be rotatable about a first axis A. A second wrist element (12) is attached to the first wrist element (11) to be rotatable about a second axis (B), and a welding torch (2) is supported via a transmission mechanism (13) to be rotatable about an offset axis (C). The welding torch (2) is attached so that a tip end thereof is directed downward in the illustrated posture of the robot (1). A linear guide (6a) and a slider (7) are provided via a support base (5), and an intermediate portion of a torch cable (3) or a welding wire delivery device (4) is fixed thereto to draw a tensioning device (80). Such a structure is also applicable to a wall-hanging type robot. Thereby, a structure for treating a torch cable (3) is realized in an arc welding robot (1) of a ceiling-suspension type or a wall-hanging type, capable of maintaining the behavior of the torch cable (3) in a stable state as well as minimizing the interference of the torch cable (3) with other objects.
