Cleaning structure and weight stack machining and drilling device

The utility model relates to the technical field of weight stack drilling and cleaning, in particular to a cleaning structure and a weight stack machining and drilling device, which are characterized in that a fixing frame and a second positioning plate are arranged on the surface of a machining table, a bottom plate and a mounting plate are arranged on two side surfaces of the machining table, and a blowing frame is arranged on the surface of a support frame; the drilling device has the beneficial effects that when the drilling device is used, a weight stack is firstly placed on the machining table, then the clamping device is used for clamping and fixing the weight stack, then the drilling device can be used for machining and drilling the surface of the weight stack, and when many chippings are generated during drilling, a supporting frame can be pulled up to enable an air blowing frame to be aligned with the surface of the machining table; and then, an air blowing pump is started to blow chippings accumula
