Numerical control machining tapping device with cleaning function

The utility model discloses a numerical control machining tapping device with a cleaning function, which comprises a bottom table, and bottom feet are respectively fixed at four corners of the bottom end of the bottom table. According to the numerical control machining tapping device with the cleaning function, a servo motor on one side of the bottom table is started, a gear box is used for driving a connecting shaft to rotate, the connecting shaft rotates to drive fixing blocks fixed to the two sides of the outside to rotate at the same time, and the fixing blocks rotate to drive hinged connecting rods to ascend; meanwhile, a connecting rod ascends to drive a fixing foot hinged to the top end to ascend, a workbench and a tapping assembly arranged at the top end of the workbench can be driven to be lifted, and a servo motor rotates to drive a fixing block and the connecting rod to bend and stretch so that the height of the workbench can be lifted and adjusted; and meanwhile, an arranged guide rod can directio
