The present invention is provided to weld a brush assembly with a terminal installed in an upper body of a motor for a fuel pump. In a parallel-gripper type terminal welding device according to the related art in which a pressing center is offset from an electrode center, pressing force cannot be effectively transmitted, so that an electrode is instantaneously delaminated due to the mechanical tolerance such as LM guide, which degrades welding quality. According to the present invention, the pressing and the separation between the electrodes are performed by an air cylinder (160) provided at a lower end thereof with two arms (130, 140) to which electrodes (110, 120) are attached, having an intermediate part hinged by a rotational pin (150), and installed at the arm (130, 140) and a compressive coil spring, so that the pressing center and the electrode are placed at the same position. Accordingly, the electrodes does not slid or are not delaminated, so that the welding quality can be improved. |
