Title:
MOTOR DRIVEN RESISTANCE SPOT WELDING GUN
Document Type and Number:
WIPO Patent Application WO2002094496
Kind Code:
B1
Abstract:
A motor-driven welding gun has a servomotor (34) for displacing a movable electrode tip (30) toward and away from a fixed electrode tip (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).
