Abstract

The invention discloses a hub drilling device combination which comprises a workbench, a hub fixing device, a valve hole drilling device and a sensor hole drilling device. The hub fixing device, the valve hole drilling device and the sensor hole drilling device are connected to the workbench, the workbench is provided with a middle hollowed-out portion, the valve hole drilling device and the sensor hole drilling device are arranged on two sides of the hub fixing device oppositely, the hub fixing device comprises a valve slot positioning device, limited posts, an axial fixing device and a radial fixing device, the limited posts are arranged on the workbench on two sides of the middle hollowed-out portion symmetrically, and a drill bit of the valve hole drilling device, a drill bit of the sensor hole drilling device, the valve slot positioning device and the radial fixing device are arranged on vertical planes of central axes of the limited posts respectively and face toward the limited posts respectively. Two processes of atmospheric pressure sensor hole and valve hole drilling are combined to one process, a hub needs not to move, repeated positioning is not needed, machining difficulty is lowered, and qualified rate of products is improved while production efficiency is improved.

Description

technical field [0001] The invention relates to the field of wheel hub manufacturing equipment, in particular to a drilling device for drilling air valve holes and air pressure sensor holes on the wheel hub. Background technique [0002] There are valve holes and valve grooves on the hub of the car to correspond to the valves on the pneumatic tires. At the same time, there are holes on the hub for installing pressure sensors to detect the real-time pressure of the tires to ensure the safety of the vehicle. The valve groove is formed during the manufacturing process of the spoke or rim of the wheel hub, while the valve hole and the pressure sensor hole are drilled on the rim after the wheel hub is manufactured. The existing technology requires two processes to drill the valve hole and the pressure sensor hole respectively. The device hole needs to be positioned twice, the processing is difficult, the pass rate of the product is low, and the production efficiency is low. Con...
