Abstract

PURPOSE:To reduce screw fastening steps so as to enhance the working efficiency by holding two members to be fastened and a fastening member with the use of a taper pin on a robot hand body and a chuck when the two members to be fastened are coupled and fastened together by the fastening member. CONSTITUTION:A taper pin 2 on a robot hand body 1 is inserted in a hole 7b in a fastening member 5 which is clamped by a chuck 8 that can be moved in a horizontal direction. In this condition, the robot hand body 1 is moved so that the taper pin 2 is inserted into a threaded hole 10b in a member to be fastened 9b so as to align a hole 7a with a threaded hole 10a, and accordingly, a screw 12a is fastened by use of a driver 11. Thereafter, the clamp of the fastening member 5 is released so as to move the robot hand body 1 upward, and the tapered pin 2 is taken out from the hole 7b and the threaded hole 10b. Then, a screw 12b is fastened into the threaded hole 10b in the member 19b to be fastened through the other hole 7b in the fastening member 5.
