Description

Technical Field

[0001] The invention belongs to the technical field of motor production equipment, and particularly relates to a welding clamping device for motor connecting wires. Background Art

[0002] New energy vehicles and other applications have improved the stator and rotor design of their motors, gradually improving torque, power, and efficiency while reducing noise. For example, the stator winding method has been changed to a hairpin-type winding. After inserting the hairpin-type connecting wires into the stator, the corresponding hairpin-type connecting wires need to be soldered to form the winding. Because the hairpin-type connecting wires are numerous and closely arranged, the copper hairpin-type connecting wires are easily deformed, making it difficult to locate the welding points, which not only affects welding efficiency but also quality.

[0003] In the utility model patent application with publication number "CN213304556U", it relates to a motor connecting wire welding positioning tool, which solves the shortcomings of difficult positioning and low work efficiency in the prior art. It includes a motor body and a positioning seat. The motor body is provided with a plurality of connecting wires, and the motor body is provided with symmetrically arranged positioning grooves. The interior of the positioning seat is provided with a circular groove. The top of the positioning seat is fixed with symmetrically arranged guide pillars by bolts. The guide pillars are externally provided with a movable seat for sliding. The movable seat is rotatably provided with a rotating column. Through the arrangement of the positioning groove, positioning block, positioning seat, positioning plate, positioning hole, push rod and fixed pressure plate, when welding the motor connecting wires, the positioning block is used to cooperate with the positioning groove to position the motor connecting wires, while ensuring that the two welded connecting wires are inserted into the positioning hole. The positioning of the connecting wires is completed by pressing the push rod, which is convenient to operate and improves the welding accuracy. This patent application can realize the welding operation of the motor connecting wires, but because the motor connecting wires are often somewhat messy and the application does not have a structure to straighten the motor connecting wires, it has certain limitations.

[0004] In the invention patent application with the publication number "CN110102946A", a hairpin-type connecting wire welding and positioning tool for a motor is disclosed, which includes an upper turntable, a lower turntable, a rotating shaft and a locking device. A through hole is provided in the middle of the upper turntable, and the upper turntable is provided with a plurality of slots. The slots include two opposite long sides, one end of the long side points to the through hole, and the middle of one long side protrudes toward the middle of the other long side to form a partition bar. All the slots are arranged in a circle with the through hole as the center. The upper turntable and the lower turntable have the same structure. The rotating shaft can rotate through the through hole of the upper turntable and the through hole of the lower turntable in turn. Nuts are fixed at both ends of the rotating shaft. The upper turntable and the lower turntable are locked and kept relatively fixed by the locking device. The hairpin-type connecting wire welding and positioning tool for a motor of the present invention can realize the rapid positioning of the hairpin-type connecting wire of the motor, facilitate welding by the welding device, improve the welding efficiency of the hairpin-type winding of the motor, and ensure the welding quality. This patent application can use the relative movement of the slots of the upper turntable and the lower turntable to straighten the motor connecting wires, but if the rotation force of the upper turntable and the lower turntable is not well controlled, it is easy to cause damage to the motor connecting wires.

[0031] Working principle: First, fix the motor 120 to be processed in the middle of the first support ring 210 (it can be fixed using conventional technology, and the fixing method of the motor 120 to be processed is not a protection point of this application, so it will not be described in detail). At this time, the first shifting tooth 331 on the second swing rod 330 is facing downward (that is, the spacing between adjacent second swing rods 330 is relatively large), start the first drive motor 110, and the first drive motor 110 controls the rotation of the first gear 111.

Since the first sleeve is installed and restricted in the first through hole 441 on the third supporting ring 440, moving the first swinging ball 321 can make the first rotating rod 310 rotate, thereby making the second swinging rod 330 rotate, and the first moving gear 331 turns to the horizontal direction, and at the same time, the spacing between adjacent second swing arms 330 gradually decreases, combing the motor connecting wires 121 together in pairs, wherein the spacing between the first shifting teeth 331 on the second swing arm 330 is equivalent to the two motor connecting wires 121, which can ensure that the motor connecting wires 121 are stably combed together in pairs and are not easy to shake during welding. Through the change in the distance before and after the rotation of the second swing arm 330, the motor connecting wires 121 are combed together in pairs and neatly arranged, which is convenient for accurately positioning the welding points, helps to improve welding efficiency, and also improves welding quality.
