The invention discloses a motor hairpin type connecting line welding positioning tool. The tool comprises an upper rotating disc, a lower rotating disc, a rotating shaft and a locking device, whereina through hole is formed in the middle of the upper rotating disc, and a plurality of inserting grooves are formed in the upper rotating disc; each inserting groove comprises two opposite long edges,one ends of the long edges point to the through hole, and the middle of one long edge protrudes towards the middle of the other long edge to form a separation strip; and all the insertion grooves arearranged in a circumferential entire row by taking the through hole as the circle center, the upper rotating disc and the lower rotating disc are the same in structure, the rotating shaft penetrates through the through hole of the upper rotating disc and a through hole of the lower rotating disc in sequence in a rotating mode, the two ends of the rotating shaft are correspondingly and fixedly provided with nuts, and the upper rotating disc and the lower rotating disc are locked through the locking device to kept relative fixation. According to the motor hairpin type connecting line welding positioning tool, rapid positioning of motor hairpin type connecting lines can be realized so as to facilitate welding by a welding device, the welding efficiency of a motor hairpin type winding is improved, and the welding quality is ensured.
Description
technical field [0001] The invention belongs to the technical field of motor production equipment, and in particular relates to a welding and positioning tool for a hairpin-type connecting wire of a motor. Background technique [0002] New energy vehicles, etc. have improved the stator and rotor design methods of the motors they use, gradually improving the motor torque, power, and efficiency performance, while reducing noise. For example, the winding method of the stator is changed to a hairpin winding. After the hairpin-type connecting wires are inserted into the stator, the corresponding hairpin-type connecting wires need to be welded to form the winding. Due to the large number of hairpin-type connecting wires arranged closely, the copper hairpin-type connecting wires are easily deformed elastically, and the welding points are difficult to locate, which not only affects the welding efficiency, but also affects the welding quality. Contents of the invention [0003] In...
