The invention relates to the technical field of water-jet-guided
laser processing, in particular to a water-jet-guided
laser processing head based on a telescopic probe and an in-situ measurement method, and the water-jet-guided
laser processing head comprises a base which is used for being fixedly connected with a
machine tool motion unit of water-jet-guided
laser processing equipment; the processing head mounting part is fixed on the base and is used for mounting a water-jet-guided
laser processing head; and the measuring module is attached to the
machining head mounting part and is rigidly fixed on the base, so that the relative spatial position between the measuring module and the
machining head mounting part is fixed. The measuring module and the
machining head are rigidly integrated on the unified base and fixed to the
tail end of the main shaft, time waste and reference errors caused by tool changing are fundamentally eliminated, the built-in precise linear driving and
servo closed-
loop control ensure the micron-order repeated precision of probe stretching, the independent rotating air cylinder drives the protective door structure, and the working efficiency is improved. The core protection problem under the severe water-guided laser machining environment is solved, and the long-term reliability of the
system is guaranteed.
