The invention belongs to the technical field of gear processing, and concretely discloses a cleaning device for basin teeth processing. The cleaning device for basin teeth processing comprises a box body, a telescopic rod, a stepping motor, support rods, connecting rods and multiple spray heads. The telescopic rod is fixed onto the bottom part in the box body; a cavity is arranged in the telescopic rod; a screw hole communicating with the cavity is formed in the upper end of the telescopic rod; a screw rod vertically stretching into the screw hole is fixed onto an output shaft of the steppingmotor; a support sleeve for placing basin teeth is fixed to the upper part of the telescopic rod; sliding chutes are arranged on the bottom part of the box body and located under the support rods along a radial direction of the telescopic rod; the middle parts of the spray heads are hinged onto fulcrum bars; nozzles of the spray heads face the support sleeve; the lower ends of the support rods areslidably connected into the sliding chutes; the upper ends of the support rods are hinged onto the support sleeve; the lower ends of the connecting rods are hinged onto the support rods; and the upper ends of the connecting rods are hinged with one ends, far away from the nozzles, of the spray heads. Compared with the prior art, the device is time and labor saving, thorough in cleaning, and better in cleaning effect when being used for cleaning the basin teeth.
