[0002] The steering wheel is a wheel-shaped device that controls the direction of travel of cars, ships, airplanes, etc. The steering wheel is generally connected to the steering shaft through a spline, and its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. The steering wheel is mainly composed of a frame, packaging materials, airbags, horns, etc., among which the steering wheel frame is the most important structure of the steering wheel. The airbags, horns, packaging materials, etc. must be installed based on the frame.

[0003] The steering wheel skeleton is generally formed by one-piece die-casting or sheet metal forming. The one-piece die-cast steering wheel skeleton is often rough on the surface after initial forming, with defects such as burrs and flash. In order to ensure the subsequent installation accuracy of other parts on the skeleton, the surface of the steering wheel skeleton needs to be polished and flashed. At present, the polishing and flashing operation of the steering wheel skeleton is performed by manual hand-held grinding tools. Manual grinding has good grinding accuracy and comprehensive grinding positions, but it has high labor intensity for workers, low grinding efficiency in batch processing, and low production efficiency.
