Abstract

The present disclosure relates to the technical field of deep hole machining, particularly to a rear-mounted deep hole machining on-line detection and deviating correction device, which provide solution to the difficulty in observing the machining site and correcting the cutter deviation in deep hole machining. The device comprises a cutter bar provided with a plurality of iron blocks mounted uniformly in a circumferential direction, wherein each of the iron blocks is provided with a heating device in the interior thereof and a wear-resistant block mounted on the top thereof, wherein mounted on an end face of the other end of the cutter bar is a pyramid prism, wherein a laser transmitter and a photosensitive sensor are mounted in a height corresponding to the height range of the pyramid prism, wherein the incident beam emitted by the laser transmitter is oriented by a laser orientating block. The advantages of the disclosure lie in that the information of the position the deep hole cutter during deep hole machining process and whether the deep hole is skewed or not can be obtained in time, thereby facilitating a solution to the difficulty in detecting the workpiece deep hole straightness and on-line deviating correction, improving the position accuracy such as straightness of the deep hole and reducing the rejection rate of the workpiece.
