Abstract

The invention provides a method and device for self-adaptive machining of a motor base and vibration monitoring of a vertical feed shaft and a computer readable storage medium. The method comprises the following steps: detecting voltage and current of a spindle motor loop of a numerical control machine tool; calculating the real-time power of a spindle of the numerical control machine tool according to the voltage and the current; sending the real-time power of the main shaft to an industrial computer, and analyzing the real-time power through the industrial computer to obtain the feed multiplying power of the feed shaft of the machine tool; controlling the cutting speed of the feed shaft of the numerical control machine tool according to a feed multiplying power signal of the feed shaft of the machine tool; detecting a mechanical vibration value of the vertical feed shaft of the numerical control machine tool; and performing real-time analysis on the mechanical vibration value to obtain an alarm type. According to the provided method and device for self-adaptive machining of the motor base and vibration monitoring of the vertical feed shaft and the computer readable storage medium, the cutting speed of the feed shaft of the numerical control machine tool can be automatically adjusted, and the mechanical vibration value of the vertical feed shaft of the numerical control machine tool can be analyzed in real time to give an alarm.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a method, device and computer-readable storage medium for self-adaptive processing of a motor base and vibration monitoring of a vertical feed shaft. Background technique [0002] The processing time of the asynchronous motor base is often long, and because different batches of base castings have different materials, if the programmed feed rate is too high during rough machining in the processing program, it will easily cause CNC machine tool alarms or tool life shortened, and the programmed feed rate is too small, it will seriously affect the processing efficiency. In addition, the vibration of the CNC machine tool not only affects the final processing quality of the base, but also affects the mechanical life of the CNC machine tool. [0003] In the traditional processing process, the feed ratio of the CNC machine tool is at 100%. The operator manually adjusts the f...

[0002] The processing time of the asynchronous motor base is often long, and because different batches of base castings have different materials, if the programmed feed rate is too high during rough machining in the processing program, it is easy to cause CNC machine tool alarms or tool life Shorter, and the programmed feed rate is too small, it will seriously affect the processing efficiency

In addition, the vibration of the CNC machine tool not only affects the final processing quality of the base, but also affects the mechanical life of the CNC machine tool

[0003] In the traditional processing process, the feed ratio of the CNC machine tool is at 100%. The operator manually adjusts the feed ratio by listening to the processing sound of the machine tool, thereby slowing down or speeding up the processing speed of the machine tool. The operator is in a high tension easily fatigued, and at the same time cannot handle some emergencies quickly, nor can it judge the state of CNC machine tools in advance
