During the processing of automobile wheel hub, after the wheel hub is cast, it is usually necessary to perform fine processing on the bolt holes of the wheel hub, such as expanding the hole, deburring, etc. The specific operation process is to use a clamping device to clamp the wheel hub on the workbench, and then use a drilling tool to process the bolt holes of the wheel hub.

[0003] In order to improve the efficiency of drilling holes in automobile wheel hubs, the prior art has made many improvements to the drilling device for automobile wheel hubs, such as the patent publication number CN219464814U, which discloses an automobile wheel hub drilling device, including a base, the upper surface of the base is equipped with a clamping assembly for clamping the automobile wheel hub, one side of the upper surface of the base is fixedly equipped with a right angle frame, the lower surface of the right angle frame is rotatably equipped with a rotating shaft, the lower surface of the rotating shaft is fixedly equipped with a rotating plate, and one side of the lower surface of the rotating plate is equipped with a drilling assembly for drilling holes in the automobile wheel hub. After the drilling work is completed, the staff rotates the rotating plate so that the cleaning assembly follows the rotating plate to rotate above the center hole of the automobile wheel hub, and then the staff starts the cleaning assembly to clean the burrs at the center hole position, so that after the drilling assembly drills the automobile wheel hub, the staff does not need to remove the wheel hub and then place it in the burr cleaning device, the steps are simple, and there is no need to constantly move the wheel hub, which reduces the workload of the staff.
