The invention discloses a quick tool setting device for a numerically-controlled machine tool. The quick tool setting device comprises a plurality of laser transmitters, a first laser receiver and a second laser receiver, wherein the laser transmitters are mounted on a tool base; the first laser receiver and the second laser receiver are mounted on a workpiece base; the second laser receiver is located on the outer side of the first laser receiver and is coaxially arranged with the first laser receiver; some laser transmitters can directly radiate on the first laser receiver; the other laser transmitters radiate on the second laser receiver through the reflection of a plurality of reflectors; the first laser receiver and the second laser receiver are in communication connection with a controller. The invention also discloses a method using the tool setting device for setting tools. A transfer function is utilized to link two monitoring devices with each other so as to adjust in a following form. The quick tool setting device for the numerically-controlled machine tool can overcome the defects of the prior art, can increase the anti-interference property of the adjusting system and can increase the speed of tool setting operation.
Description
technical field [0001] The invention relates to the technical field of tool setting for numerically controlled machine tools, in particular to a rapid tool setting device and method for numerically controlled machine tools. Background technique [0002] Before machining, the CNC machine tool needs to perform tool setting operation, so as to ensure that the tool and workpiece are in the original position to be processed. In addition to the traditional trial cutting method and the detection method of the knife setting instrument, the following knife setting methods are also provided in the prior art: [0003] Chinese invention patent CN 102091969 B provides a non-contact tool setting method using voltage signals; [0004] Chinese invention patent CN 102172846 B provides a method of using a photoelectric sensor to capture light signals for knife setting; [0005] Chinese invention patent CN 102699359 B provides a method for tool setting based on image analysis and processing;...
