摘要： A welding gun is provided in which moisture does not penetrate inside of a motor housing due to preventing the inside of the motor housing from becoming negative pressure. The welding gun includes a feed screw mechanism (40) that is coupled to a servo motor (10) and has a hollow rod (43) that reciprocally moves in a predetermined direction by way of torque applied by the servo motor (10), and a moveable electrode tip (62) that is connected to a leading end portion of the hollow rod (43) and opens and closes relative to a fixed electrode tip (61) according to the reciprocal movement of the hollow rod (43). The servo motor 10 has a motor housing (20) in which a motor housing hollow part (25) accommodating a portion of the hollow rod (43) to be reciprocally moveable is formed. A vent (21b) that ventilates the motor housing hollow part (25) with ambient air is formed in the motor housing (20).

摘要： A welding gun precludes moisture from penetrating inside of a motor housing due by preventing development of negative pressure inside the motor housing. The welding gun includes a feed screw mechanism that is coupled to a servo motor and has a hollow rod that reciprocally moves in a predetermined direction by way of torque applied by the servo motor, and a moveable electrode tip that is connected to a leading end portion of the hollow rod and opens and closes relative to a fixed electrode tip according to the reciprocal movement of the hollow rod. The servo motor has a motor housing in which a motor housing hollow part accommodating a portion of the hollow rod to be reciprocally moveable is formed. A vent that ventilates the motor housing hollow part with ambient air is formed in the motor housing.

摘要： A moving die is held by a robot and made to approach a vehicle, and a positioning pin is inserted into a positioning hole of the vehicle. The moving die is brought into a floating state of being displaceable relative to the vehicle by reducing a force of the robot for maintaining an attitude thereof. In a state of holding the moving die by the robot, a surface of the moving die is brought into contact with the vehicle by an adsorbing mechanism including an adsorbing portion of an elastic member provided to the moving die. The moving die and the robot are cut to be separated.

摘要： In a roller hemming method for folding a flange erected from a workpiece by pressing a working roller against the flange and moving the working roller relative to the flange, the flange is folded by: a first temporary bending step of bending a tip-side portion of the flange into a state that the tip-side portion is inclined; a second temporary bending step of bending a remaining, base-side portion of the flange into a state that the base-side portion is inclined; and a full bending step of bending the thus-bent flange into a final shape so that the flange is into contact with a flange-proximate portion.

摘要： A seam welding apparatus and a seam welding method perform a seaming process on workpieces of various shapes having flange sections, by preventing a welding track formed by upper and lower rotary electrodes from becoming displaced from a welding reference line established on the flange section. The seam welding apparatus includes two rotary electrodes for gripping the flange section therebetween while seam-welding the flange section, a support for synchronizing movements of the two rotary electrodes with each other in a widthwise direction of the flange section, a turning mechanism for pressing at least one of the two rotary electrodes toward the workpiece body, a roller that abuts against an end face of the flange section, and roller adjusting means for positionally adjusting the roller.
