Abstract: The disclosure relates to a technical field of deep hole machining, particularly to a deep hole machining on-line deviating correction device based on laser detection, which solves the prior art problem of difficulty in the real-time, on-line detection and deviating correction in the process of deep hole machining. The device comprises a deep hole cutter and a cutter bar, and arranged on the cutter bar are a laser orientating block, a pyramid prism seat, the deep hole cutter and a metallic block with a heating device arranged therein. A beam emitted by a laser transmitter is orientated by the laser orientating block so as to be incident in parallel with the axis of the cutter bar, and then through a pyramid prism to form a return beam which reaches the photosensitive sensor.
