In industrial manufacturing, a worker usually uses a drilling machine to drill a hole in a workpiece, holds one end of the workpiece, which is not to be drilled, with one hand, and extends the other end of the workpiece below a drill bit of the drilling machine, and simultaneously turns on a switch of the drilling machine or presses down the drill bit of the drilling machine, so that the drilling machine drills the hole at a position where the hole needs to be drilled.

Because the processing mode is adopted, the workpiece is positioned only by manually holding the workpiece with one hand, and the workpiece is easy to move in the drilling process, so that the drilling position of the drill bit is deviated, the workpiece is scrapped, and workers are easy to hurt. Meanwhile, the chips generated in the drilling process fly out to scratch equipment and operators easily. And because the volume of the scraps is small, the scraps are not easy to clean after entering the equipment, the scraps accumulated for a long time often bring potential safety hazards for production, and if the scraps are sucked into the lung by mistake, the scraps can also damage the human body.

Based on the above, a wiring hole drilling device and a drilling method are urgently needed to solve the problem that when a workpiece wiring hole is drilled, the position of the wiring hole to be processed deviates from the position of a drill bit due to the movement of the workpiece, so that the quality of a finished product is influenced; and because the piece flies indiscriminately difficult problem of clearing up, prevent that the piece from flying indiscriminately simultaneously and bring the potential safety hazard to workman and equipment.
