AI Technical Summary

Technical Problem

Existing progressive multi-point lubrication systems in machine tool tool changing mechanisms suffer from insufficient oil supply accuracy control, leading to under-lubrication or over-lubrication at some lubrication points. This is particularly problematic under conditions of limited tool change intervals, differences in branch pipeline characteristics, and temperature fluctuations, where the final oil supply volume deviates significantly.

Method used

By pre-calibrating each lubrication branch, the relationship between pipeline resistance and oil supply parameters is obtained, a basic compensation coefficient is established, and the compensation coefficient is dynamically corrected in combination with real-time temperature and available time window to determine the target oil supply parameters and achieve quantitative control of multi-point lubrication.

Benefits of technology

It effectively solves the problem of deviation in the oil inlet volume at the end caused by the characteristics of the working conditions, ensures that the actual oil inlet volume of each lubrication branch is consistent with the demand, improves lubrication reliability, and extends the service life of the tool changing mechanism.

Abstract

The present application relates to the technical field of machine tool intelligent lubrication, and particularly relates to a multi-point lubrication control method and system for tool changing of a machine tool and a storage medium, the method comprising: pre-calibrating each lubrication branch of a progressive multi-point lubrication system, obtaining the corresponding relationship between the pipeline resistance and oil supply parameters of each lubrication branch and the actual oil inlet amount at the end, and obtaining the basic compensation coefficient of each lubrication branch; obtaining the available time window of tool changing of the machine tool and the real-time temperature of the lubricating medium in real time; dynamically correcting the basic compensation coefficient according to the real-time temperature to obtain the real-time compensation coefficient of each lubrication branch; determining the target oil supply parameter of the lubrication actuator based on the real-time compensation coefficient and the available time window, and controlling the lubrication actuator to execute oil supply according to the target oil supply parameter. Through the present application, lubrication control within the tool changing gap of the machine tool can be realized, oil supply and tool changing actions can be avoided from being in conflict, and the deviation of the oil inlet amount at the end caused by working condition fluctuations can be offset, thereby ensuring the lubrication reliability.
