Intelligent switching system for switching internal cooling and external cooling based on minimal quantity lubrication and method

An intelligent switching system for switching internal cooling and external cooling based on minimal quantity lubrication, wherein the intelligent switching system comprises a vision system, a cooling system, and a control system;

• the vision system is configured to monitor a milling state of a cutter of a machine tool in real time, collect a real-time milling depth image that the cutter mills a workpiece, and transmit the real-time milling depth image that the cutter mills the workpiece to the control system through a first wireless transmission device;
• the control system comprises a lubrication mode control center, a second wireless transmission device, a motor control center and a third wireless transmission device;
• the lubrication mode control center is connected with the second wireless transmission device;
• the second wireless transmission device is configured to receive a real-time image transmitted by an image collection control center;
• the lubrication mode control center is configured to analyze and process the real-time milling depth image that the cutter mills the workpiece to obtain real-time milling depth data of the cutter, and configured to compare the real-time milling depth data with a preset milling depth threshold to obtain a lubrication mode in current a machining condition based on a comparative result;
• the third wireless transmission device is configured to receive a signal sent by the lubrication mode control center;
• the motor control center is configured to analyze and process the signal to obtain a control instruction;
• and the third wireless transmission device transmits the control instruction to the cooling system;
• the cooling system is configured to execute a command of switching the internal cooling and the external cooling sent by the motor control center, so as to realize the internal cooling and the external cooling for the machine tool.
