  • Motor driven resistance spot welding gun
    Patent number: 7067768
    Abstract: A motor-driven welding gun has a servomotor for displacing a movable electrode tip toward and away from a fixed electrode tip. The servomotor has a motor housing with a copper pipe which is inserted therein when the motor housing is cast. The copper pipe provides a coolant passage in the motor housing for supplying a coolant therethrough. When the coolant passage is supplied with the coolant, the motor housing is forcibly cooled, reducing the amount of heat generated by the servomotor.

  • Motor driven resistance spot welding gun
    Publication number: 20040208031
    Abstract: A motor-driven welding gun has a servomotor (34) for displacing a movable electrode tip (30) toward and away from a fixed electrode (32). The servomotor (34) has a motor housing (38) with a copper pipe (72) which is inserted therein when the motor housing (38) is cast. The copper pipe (72) provides a coolant passage (70) in the motor housing (38) for supplying a coolant therethrough. When the coolant passage (70) is supplied with the coolant, the motor housing (38) is forcibly cooled, reducing the amount of heat generated by the servomotor (34).
