The invention provides a
deep hole machining device and method. The
deep hole machining device comprises a
machine tool body, the
machine tool body is fixedly provided with a drilling power head, a
deep hole drilling head is installed on the drilling power head, a
workbench is slidably installed on the
machine tool body through a guide rail, the
workbench and the
machine tool body are further connected through a screw rod nut mechanism, a workpiece is clamped on the
workbench, the deep hole
machining device is further provided with a
laser assisted calibration device and an electromagnetic deviation correcting device, a deviation correcting hole is punched in the position of the workpiece to be machined by
laser, a
laser beam emitted by a laser emitting device is made to fall on a photoelectric collector, and deviation of the
deep hole drilling head is corrected in real time through the electromagnetic deviation correcting device. By means of adoption of the above scheme of the deep hole machining device and method, the structure is simplified, and improvement of the machining precision is facilitated; by means of the arrangement of the
laser assisted calibration device, online precision calibration can be realized, and deviation errors can be detected in real time according to the collimating laser
shape change and different positions of the photoelectric collector where the laser falls on; and by means of the arrangement of the electromagnetic deviation correcting device, the deviation of the
deep hole drilling head can be corrected in real time, and the machining precision is further improved.
