[0048] In the related art, a mechanical structure is used to measure the hole depth. The mechanical structure is complex, requires maintenance, and is troublesome to measure. In addition, the measurement accuracy is not high.

A measuring table is arranged on the outer wall of the tailstock of a lathe, and a laser measuring component is arranged on the measuring table. The measuring end of the laser measuring component is consistent with the direction of the drill bit. When the drill bit starts drilling, the laser measuring component uses a laser to measure and record the distance between the end face of the drill hole and itself. After the drilling is completed, the drill bit penetrates into the end face of the drill hole, and then uses the laser measuring component to measure the distance between itself and the end face of the drill hole. The drilling depth can be obtained by subtracting the distance measured after the drilling is completed from the distance measured at the beginning of the drilling. This allows the measuring mechanism to perform measurements without using a mechanical structure, so that the device has a simple structure, does not require maintenance, can perform measurements quickly, and has high laser measurement accuracy.
