Wheel hub polisher

The utility model belongs to the technical field of wheel hub machining equipment and relates to a polisher, in particular to a wheel hub polisher which solves the technical problem that the prior art is unreasonable. The wheel hub polisher is characterized in that a plurality of wheel hub rotation driving and feeding devices located on the periphery of a grinding material drum are arranged on a worktable; each wheel hub rotation driving and feeding device comprises a mechanical arm and a rotating clamp assembly, wherein the rotating clamp assemblies are used for fixing wheel hubs and can drive the wheel hubs to rotate; the rotating clamp assemblies are arranged on the mechanical arms, and the mechanical arms are arranged on a feeding mechanism, wherein the feeding mechanism can drive the mechanical arms to act to enable the wheel hubs arranged on the rotating clamp assemblies to enter the grinding material drum or move out of the grinding material drum, and the feeding mechanism is arranged on the worktable. Compared with the prior art, the wheel hub polisher has the advantages of being reasonable in design, simple in structure, convenient to use and operate, ideal in polishing effect, high in degree of automation, capable of meeting different machining requirements and completing rough polishing and finishing polishing on the same machine, and saving in acquisition cost of machines of enterprises.
