Description

Technical Field

[0001] The utility model relates to the technical field of motor end - cover welding, in particular to a welding device for a motor end - cover and a wire. Background Technique

[0002] A motor is a common electric motor, and its structure mainly includes two major parts: a stator and a rotor. The stator is the stationary part of the motor, and it includes a motor end - cover. As Figure 10 shown, when assembling the motor end - cover 71, it is generally necessary to insert a wire 72 and then perform welding. The seat body of the motor end - cover 71 is provided with end - cover positioning notches 73 at intervals around an arc. After user feedback, it is found that the welding part between the motor end - cover 71 and the wire 72 is prone to looseness and is extremely easy to be pulled off, and the safety performance is poor. After analysis, it is because when welding the motor end - cover, manual threading is adopted and then transferred to the next station for ordinary welding. Manual operation is likely to cause poor consistency of the welding position, low qualified rate of the welded products, and the wire at the welding point is exposed to the outside during welding. Therefore, improvements and optimizations are carried out. Summary of the Utility Model
