Numerical control machine cutter head fault diagnosis system

Abstract

The invention provides a numerical control machine cutter head fault diagnosis system. A central processing device, a vibration sensor, a signal processing circuit, an A / D conversion module, an imagecollection module, an image processing module, a power supply module, a comparison module, a warning device, a wireless transmission device, a user control end, a display device and a storage device are used, so that the effective monitoring on a cutter head of a numerical control machine can be realized; the vibration parameters of the cutter head in the processing process can be tested through the vibration sensor; the vibration parameters can be combined with the preset vibration threshold; the image information of the cutter head can be collected through the image collection device; workers can effectively monitor the cutter head of the numerical control machine by combining the cutter head image information and the cutter head vibration signals collected by the vibration sensor; the image processing module sequentially performs image enhancing, image smoothening, image sharpening and image grayscale conversion processing on the collected images.

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
