The invention discloses an aluminum
alloy hub drilling device which comprises a box and a clamping device. A
machine base is fixedly connected to the interior of the box, a first motor and a water pump are sequentially and fixedly installed at the upper end of the
machine base from left to right, a water tank is arranged at the position, located above the
machine base, of the upper right corner of an inner cavity of the box, a
machining chamber is arranged in the middle of the inner cavity of the box, a
sewage pool is arranged at the bottom of the inner cavity of the box, and a first gear is fixedly installed at the front end of a first motor output shaft. The aluminum
alloy hub drilling device relates to the technical field of car part manufacturing equipment. According to the aluminum
alloy hub drilling device, water is pumped from the water tank through the water pump, water is sprayed out from a double-direction spraying
nozzle by means of a drainage
pipe sequentially penetrating a hollow rack, a rotating shaft, a hollow shaft and a machine case, the water is sprayed to a
drill bit and a
polishing head at the same time, sprayed water can scour
metal chippings, and it is guaranteed that the
metal chippings cannot drift away; and meanwhile, the drilling bit and the
polishing head can be cooled, the service life of the drilling bit and the
polishing head can be prolonged, and cost losses are reduced.
