  • External cooling MQL manipulators and machine tools and lubrication method using machine tools
    Patent number: 11465252
    Abstract: This application relates to lubrication, and more particularly to an external cooling MQL manipulator and a machine tool and a lubrication method using the machine tool. The external cooling MQL manipulator includes a suspension structure, a robot arm, a controller and an oil mist generator. The suspension structure fixedly connects the robot arm and a frame, and a nozzle is provided on a free end of the robot arm; an oil mist generator is connected to the nozzle for ejecting oil mists to a processing area. When the machine tool works, the controller selects the corresponding lubrication parameters according to the processing parameters such as the cutter type and the workpiece material. The first motor and the second motor are controlled to rotate by the controller according to real-time changes of the processing positions detected by the detecting component, thereby adjusting the position of the nozzle.
