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. The advantages of the disclosure lie in that skewing of the deep hole cutter can be detected in time and skewing correction of the deep hole tool is achieved based on the heat expansion and cold contraction mechanism, and therefore the straightness and position accuracy during deep hole machining are improved.
