Abstract
The present invention provides an automatic wheel rim online drilling device, comprising a frame, an air cylinder, a profiling drill jig, a drill bush, a servo electric cylinder, a drilling power head, etc. Firstly, a sensor enables a wheel to be positioned, and the air cylinder causes left clamping blocks to move rightward by two guide rods and guide sleeves so as to clamp the wheel jointly with a right clamping block; the servo electric cylinder causes a drilling system to move toward the wheel and the profiling drill jig can first come into good contact with the wheel rim and then the servo electric cylinder moves continuously to compress upper and lower springs so that the drill bit enters the drill bush, and at this time the drilling power head drives the drill bit to rotate, thus starting drilling on the wheel rim. By using the device of the present invention, X-ray rejects of wheels can be automatically marked by drilling, and the device can adapt to flow casting spun blanks with thick rims; and through orientation of the drill bush, the situation that the drill bit is frequently broken when drilling on the arc surface of the outer side of the wheel rim can be effectively avoided.
