[0002] The wheel hub is a round metal part that supports the tire with its inner contour. The wheel hub of an electric vehicle is mainly made by cutting a steel strip, rolling it into a circle, and then welding the two ends of the steel strip together to form a weld between the two ends of the steel strip. At present, when welding the wheel hub of an electric vehicle, workers need to clamp the two ends of the wheel hub in place by operating a fixture. When the laser head welds the two ends of the wheel hub, the worker pushes the fixture to drive the wheel hub forward so that the laser head can complete the overall welding of the wheel hub.

The top of the support 11 is provided with an X-axial driving cylinder 131 drivingly connected to the X-axial slide 130.
