Numerically-controlled machine tool bit fault diagnosis system

Abstract

The invention provides a numerically-controlled machine tool bit fault diagnosis system. The numerically-controlled machine tool bit fault diagnosis system comprises a central processing apparatus, avibration sensor, a signal processing circuit, an A / D conversion module, an image acquisition module, an image processing module, a solar uninterruptible power supply module, a comparison module, an alarming apparatus, a wireless transmission apparatus, a user control end, a display apparatus and a storage apparatus. By adopting the numerically-controlled machine tool bit fault diagnosis system, the tool bit of a numerically-controlled machine tool can be effectively monitored, not only can the vibration parameter of the tool bit in the machining process be tested by virtue of a vibration sensor, and the vibration parameters be compared with a preset vibration threshold value, but also the image information of the tool bit can be acquired by virtue of an image acquisition apparatus, the working personnel can effectively monitor the tool bit of the numerically-controlled machine tool according to the tool bit vibration signal and the tool bit image information acquired by the vibrationsensor, and the image processing module successively performs the image enhancing, image smoothening, image sharpening, and image grey level transformation processing for the acquired image.

Description

technical field [0001] The invention relates to the technical field of intelligent testing, in particular to a CNC machine tool head fault diagnosis system. Background technique [0002] CNC machine tool is the abbreviation of Computer numerical control machine tools. It is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions and decode them. , represented by coded numbers, input into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. CNC machine tools solve complex, precise, small-batch, and multi-variety parts processing problems. It is a flexible, high-efficiency automatic machine tool that represents the devel...

Problems solved by technology

Tool detection is divided into direct detection and indirect detection. The direct detection method needs to remove the tool from the CNC machine tool, which affects the processing efficiency of the CNC machine tool. The indirect detection has the advantages of real-time and convenience. different, the accuracy of test results obtained by using indirect detection methods is not high
