Problems solved by technology
However, due to the complex manufacturing process and difficult product design, there is no mature mass production line in the market at present. Hairpin motors are high-end products in China and even in the world; There are hundreds of pins in the Hairpin above 8 layers, and the copper wire end welding needs to be completed within the required beat
Because there is a gap between adjacent copper wires in the same slot, the welding cannot connect two copper wires, so high requirements are placed on the welding process; although there are currently some welding tools for welding the ends of the stator copper wires of Hairpin motors, these Even the tooling cannot be effectively fixed by the flat wire, resulting in inaccurate welding and low efficiency

The invention belongs to the field of flat wire motor stator welding, and specifically discloses a flat wire motor stator welding device, which includes a workbench, a controlled tungsten arc welding torch installed on the workbench, and a controlled tungsten arc welding torch installed on the workbench and driven The X-axis module and the Y-axis module for the controlled tungsten arc welding torch to reach the designated position, the clamping tool for fixing the flat wire, and the rotating tool for driving the clamping tool to rotate; the clamping tool It includes a tightening fixing plate detachably installed on the rotary tooling, an annular tightening disc assembled on the tightening fixing plate in rotation, fixed on the tightening fixing plate and sleeved on the annular tightening disc The tightening guide disc inside, the clamping disc arranged on the said tightening guide disc; the present invention has the advantages of being easy to use, capable of effectively fixing flat wires, convenient for welding operation, and high in work efficiency.
Description
Technical field [0001] The present invention belongs to the field of flat wire welding the motor stator, in particular to a flat motor stator wire welding process welders installed. Background technique [0002] Hairpin PMSM drive motor in the domestic market is gradually scale application compared to conventional winding type motor, since the characteristics of the flat copper Hairpin, at the same power, the motor is smaller, higher power, is the next generation of new energy-driven development direction of the motor. However, because the manufacturing process is complex, difficult to design the product, so now the market is not mature production lines, Hairpin motor, both in the domestic and global high-end products; in the production of motor Hairpin, Hairpin need for copper wire motor end of the stator welded portion, less than 8 Hairpin pin has hundreds of feet, complete copper end welded within the required tempo. Since the gap between the adjacent grooves with copper, lead...
