Four-axis tapping structure of vertical machining center

The four-axis tapping structure of the vertical machining center comprises a base, a stand column is fixedly connected to the side face of the base, and a spindle box is connected to the surface of the stand column in an up-down sliding mode; according to the four-axis vertical machining center, in the process of punching and tapping a workpiece through the four-axis vertical machining center, scrap iron on the surface of the workpiece and in a drilled hole is cleaned through the cleaning opening and the blowing opening, the scrap iron on the surface of the workpiece can be sucked in through the cleaning opening, cleaning of the scrap iron on the surface of the workpiece is facilitated, and then the blowing opening can move to the surface of the workpiece; when the workpiece surface is punched, air blown out by the fan can be blown out through the blowing pipe and the blowing opening, when the blowing opening moves to the punching position of the workpiece surface, the air blown out by the blowing opening can
