The utility model belongs to the technical field of
polishing devices, and particularly relates to a tricycle spindle
polishing device which comprises a
workbench and a
polishing box, and a polishing mechanism and a dust collecting mechanism are arranged above the
workbench. The
grinding mechanism moves transversely and longitudinally, adjusts the
grinding depth and moves in the length direction of the tricycle main shaft, and the action of
grinding the surface of the tricycle main shaft is achieved. And the dust collecting mechanism is arranged above the grinding mechanism and is used for sucking dust generated by grinding the workpiece, so that the action of intensively collecting the dust generated by grinding is realized. According to the grinding device for the tricycle spindle, the grinding mechanism and the dust collecting mechanism are arranged, the grinding mechanism grinds the surface of the tricycle spindle, the dust collecting mechanism is arranged above the grinding mechanism, dust generated by grinding workpieces is collected in a centralized mode, and the problem that when an existing grinding
machine works, the grinding efficiency is high is solved. And a large amount of dust damages operators and components of the grinding
machine.
