An automatic tool changing system for CNC machine tools

Abstract

The invention relates to an automatic cutter changing system for a numerically-controlled machine tool. The system comprises an image acquisition module, an image processing module and a cutter changing module which are sequentially connected, wherein the image acquisition module is used for shooting an image of a cutter on a machine tool main body and transmitting the image of the cutter to the image processing module; the image processing module is used for receiving the image of the cutter and judging whether the size of the cutter on the received cutter image reaches a scrap size; and the cutter changing module is used for receiving a cutter changing instruction and selecting the same cutter to replace the scrapped cutter so as to continue a machining process. The system is simple in structure, realizes monitoring of a running state of the cutter, and can automatically change the cutter according to the monitored cutter state when the numerically-controlled machine tool is in an unattended state; the machining precision of a workpiece is not influenced; the machining time is not waste; the machining efficiency is high; and the system is suitable for extensive application in the machining field.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to an automatic tool changing system for numerical control machine tools. Background technique [0002] In the application process of CNC machine tools, various tools are often involved. During the specific use of the tool, depending on the use environment, use parameters, and use time, the tool will be worn to varying degrees, and the wear of the tool , will directly affect the precision of machining, the efficiency of machining and the economic benefits of enterprises. Especially when the CNC equipment is in a semi-closed state, it is difficult for the operator outside the equipment to observe the state of the tool. If the tool breaks during the processing of the equipment, it may even endanger the personal safety of the operator. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic too...
