Rim valve hole automatic drilling equipment

The invention relates to automatic rim valve hole drilling equipment which comprises a workbench, at least one first positioning protrusion and two second positioning protrusions capable of moving towards the first positioning protrusions are arranged on the workbench, and the first positioning protrusions and the second positioning protrusions are matched with each other to position a rim. A pressing plate capable of moving up and down is arranged above the workbench and corresponds to the position above the rim fixing position, and a drill bit capable of moving towards the side wall of the rim and drilling is further arranged on the workbench. The device has the advantages that the horizontal position of the rim can be kept, radial stability and axial stability of the rim during machining are guaranteed, drilling position deviation is avoided, drilling position accuracy is effectively guaranteed, drilling stability and efficiency are guaranteed, and the like. 本发明涉及一种车圈气门孔自动钻孔设备，包括工作台，所述工作台上设有至少一个第一定位凸起和两个可朝
