Description

technical field [0001] The invention belongs to the technical field of measurement and control of machine tool spindles on industrial sites, and relates to an intelligent online monitoring and comprehensive diagnosis system for machine tool spindles based on the Internet. Background technique [0002] With the gradual improvement of my country's industrial level, higher requirements have been put forward for industrial processing capacity. High-speed, ultra-high-speed, high-precision and high-efficiency have become the basic demands of modern industrial development. Then, the only way to improve the efficiency and precision of industrial processing is to improve the degree of industrial automation and intelligence. CNC machine tools are one of the most important equipment for industrial processing, and machine tool spindles are the core functional components of CNC machine tools. Therefore, the degree of automation and intelligence of electric spindles will directly affect ...

Problems solved by technology

[0003] Since the on-site workers do not have the ability to detect and diagnose early faults, a general mechanical failure is already a serious destructive fault. At this time, the maintenance needs to be shut down for a long time, which not only seriously affects the degree of automation of processing, but also causes unnecessary economic costs. It can be seen that automatic online monitoring and fault diagnosis have practical significance for improving industrial automation and creating economic benefits

[0004] Due to the complexity of the industrial site environment, various interferences are mixed together, which brings difficulties to accurate and effective testing and data transmission on site

The control methods of modern industry are diversified, and the combination of multiple control methods is used more to support the operation of the entire machine, especially limited by supporting technologies such as input and output equipment, frequency conversion devices, and multiple sensors, making the control The method is more complicated, which brings great difficulties to the signal transmission and management between devices

The traditional transmission method not only cannot meet the multi-task transmission requirements of the comprehensive test system, but also has poor real-time performance, which affects the improvement of automation. It can be seen that it is very necessary to adopt Internet transmission technology such as industrial Ethernet and field bus technology

[0005] Spindle vibration is an important factor to reflect the working state of the spindle. Excessive spindle vibration not only seriously affects the machining accuracy and efficiency of the machine tool, but even causes serious damage to its functional components; the temperature rise of the key parts of the spindle reflects the location of the spindle. The working state and the effect of lubrication and cooling; tool wear will have an important impact on the processing process, premature tool change will reduce processing efficiency and affect economic benefits, and late tool change will deteriorate the processing quality and produce waste products; and Tool damage will interrupt the machining process and may cause production accidents. Therefore, monitoring the vibration of the spindle, the temperature of key parts of the spindle, and the status of the tool is of great significance

[0006] There are obvious disadvantages in the regular maintenance and damage repair of the machinery and equipment used in traditional industrial processing, and it is impossible to adjust the deviation in the processing process in real time, which is easy to cause the superposition of processing errors and cannot guarantee the processing accuracy

In addition, there are usually difficult faults, which cannot be solved by ordinary technical personnel and means, and the convenient transmission diagnosis platform, so that the expert consultation cycle is longer, causing unnecessary economic losses
