Description
Technical Field
[0001] The utility model relates to a welding gun moving assembly for transmission shaft welding. Background Art
[0002] The drive shaft is a mechanical element used to transmit power and torque, and is commonly found in various vehicles and mechanical equipment. Its main function is to transfer power from the engine or motor to the wheels or other working parts to make them rotate or move. The drive shaft is usually made of one or more metal materials, such as steel or aluminum alloy. It has a long strip shape, with different parts connected at both ends, such as the engine output shaft and the wheel shaft. Drive shaft welding refers to connecting different parts of the drive shaft together through a welding process to form an integral structure. The drive shaft is usually composed of multiple parts, such as axle tubes, shaft heads, bearings, etc., which need to be connected before assembly.

In addition, the drive shaft usually has a complex geometric shape, including curves, inclination angles, etc. The traditional welding gun moving device is difficult to meet the welding requirements of complex shapes, resulting in increased welding costs.
