Aluminum alloy hub drilling device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing equipment, in particular to an aluminum alloy wheel hub drilling device. Background technique [0002] The wheel hub is a barrel-shaped metal part whose center is mounted on the shaft, and is also called a rim, a steel ring, a wheel, and a tire bell. Wheel hubs are divided into many types according to the diameter, width, molding method and material. In the past, the wheel hub bearings of cars mostly used single-row tapered roller or ball bearings in pairs. With the development of technology, car wheel hub units have been widely used in cars. The use range and amount of hub bearing units are increasing day by day, and it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply fit the bearing on the wheel shaft and fix it with...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an aluminum alloy wheel hub drilling device, which solves the problem of drilling first and then grinding, which requires long processing time and low efficiency. During mass production, the drill bit and the grinding head work continuously to maintain High temperature, easy to damage, and a large amount of powdery debris will be produced during grinding, which is easy to scatter around or float into the air, affecting the working environment, and being inhaled by workers will also affect the health of workers
