The invention discloses a processing technology of an aluminum alloy workpiece and a full-automatic binding machine. The processing technology is characterized in that the steps of sealing and blocking a hole head and removing a rubber plug are added in an existing aluminum alloy workpiece technology, wherein pores in the workpiece are sealed and blocked through rubber nails after the mechanical processing, and the rubber nails are automatically removed through a clamp after the surface treatment processing is completely completed, so that the pores in the workpiece can be effectively protected and can be prevented from being polluted or blocked during the processing. The automatic blocking machine for the pores in the workpiece comprises a rubber nail positioning jig, a rubber nail blowing mechanism and a rubber nail pressing mechanism, wherein the rubber nail blowing mechanism and the rubber nail pressing mechanism are mounted on a rack; an elastic rubber nail clamping hole is formed in a position, corresponding to each pore in the workpiece, on the rubber nail positioning jig; the rubber nails are temporarily fixed above the pores in the workpiece through the rubber nail positioning jig, so that the rubber nails can be pressed into the corresponding pores in the workpiece through nail pressing needles, and as a result, the work of sealing and blocking the pores in the workpiece can be fully automatically finished; the rubber nails can be stably and reliably pressed, so that the production efficiency is improved, and the production cost is reduced.
