Gear cleaning device for machining

The invention belongs to the technical field of machining, particularly relates to a gear cleaning device for machining. The gear cleaning device aims at solving the problems that most traditional gear cleaning devices are simple in structure, lack direct brushing treatment on gears and are poor in cleaning effect. According to the following scheme, the gear cleaning device comprises a cleaning cylinder, a transmission bottom box is fixed to the outer wall of the bottom of the cleaning cylinder through bolts, the transmission bottom box and the cleaning cylinder are rotationally connected withthe same rotating column through bearings, a protruding key is welded to one side of the circumferential outer wall of the rotating column, and gears and separation cylinders are sequentially arranged on the outer wall of the rotating column in a staggered mode; and a first-order cleaning mechanism and a second-order cleaning mechanism are installed on the two sides of the cleaning cylinder correspondingly.
