Tool damage detection device for vertical machining center and detection method of tool damage detection device

The invention discloses a vertical machining center cutter damage detection device and a detection method thereof, and belongs to the technical field of vertical machining centers. The vertical machining center cutter damage detection device comprises a metal processing cabin and a machine tool body, the metal processing cabin is arranged above the machine tool body, and a metal box door is arranged on the outer surface of the metal processing cabin. In order to solve the problems that in the cutting machining process of a cutter, some workpiece scraps can be attached to the surface of a cutting edge, if the scraps are not cleaned in time, the precision of picture information can be influenced when the cutter is detected, and then misjudgment occurs, an air pump is used for conveying high-pressure air to an air injection valve nozzle through a U-shaped air pipe; and the high-pressure gas is jetted out by utilizing the gas jetting valve nozzle, so that the scraps on the surface of the cutter are cleaned, and t
